Extract all the resource related operations to analogix_dp_probe() and analogix_dp_remove(), then call them before/after registration of the device components from the main Exynos DP and Rockchip DP drivers. Also move the plat_data initialization to the probe() to make it available for the analogix_dp_probe() function.

Ultimately linking both buses to a same dma-ranges property. The patch (and author) missed the fact that a bus' #address-cells and #size-cells properties are not inherited, but set to a fixed value which, in this case, doesn't match /soc's. This, although not breaking Linux's DMA mapping functionality, generates ugly dtc warnings. Fix the issue by adding the correct address and size cells properties under the firmware bus.

Unfortunately, this change was made for *all* tablets, even those which aren't generic. Because `wacom_wac_report` ignores reports from non- generic devices, the contact count never gets initialized. Ultimately this results in the touch device itself failing to probe, and thus the loss of touch input. This commit adds back the fixed-offset extraction for non-generic devices.

Both bytes of the 16-bit command need to be written in turn to a single 8-bit data register. However, the driver currently only writes the low 8-bits. It is broken and appears to have always been broken. Electronic copies of the DT2815 User's Manual seem impossible to find online, but looking at the source code, a best guess for the sequence the driver intended to use to write the analog output command is as follows: 1. Wait for the status register to read 0x00. 2. Write the low byte of the command to the data register. 3. Wait for the status register to read 0x80. 4. Write the high byte of the command to the data register. Step 4 is missing from the driver. Add step 4 to (hopefully) fix the driver. Also add a "FIXME" comment about setting bit 0 of the low byte of the command. Supposedly, it is used to choose between voltage output and current output, but the current driver always sets it to 1.

That is because when plugging, the headphone triggers a unsol event first, and about 0.7s later (on the Lenovo X1 Carbon 7th), the Mic triggers a unsol event. But if the codec driver enters runtime suspend within 0.7s, the Mic can't trigger the unsol event. If we don't set autosuspend_delay to a non-zero value for the hda codec driver, it will enter runtime suspend immediately after the headphone triggers the unsol event. Follow the sequence of legacy hda driver and set a autosuspend delay of 1sec after card registration (refer to pci/hda/hda_intel.c and pci/hda/hda_codec.c).

The resolved slot can be invalid if the binary search loop terminated because the search index was incremented beyond the number of used slots. This bug has existed since the binary search algorithm was introduced, but went unnoticed because KVM statically allocated memory for the max number of slots, i.e. the access would only be truly out-of-bounds if all possible slots were allocated and the specified gfn was less than the base of the lowest memslot. Commit 36947254e5f98 ("KVM: Dynamically size memslot array based on number of used slots") eliminated the "all possible slots allocated" condition and made the bug embarrasingly easy to hit.

The first time the test is ran, the initial index value of 0 is valid and the test is able to complete. The index value of 0 is not valid in subsequent test runs and the loop attempts to try index values of 1, 2, 3, and so on until a valid index value is found that corresponds to the message queue created earlier in the test. The msgctl() syscall returns -1 and sets errno to EINVAL when invalid index values are used. The test failure is caused by incorrectly comparing errno to -EINVAL when cycling through possible index values. Fix invalid test failures on subsequent runs of the msgque test by correctly comparing errno values to a non-negated EINVAL.

This prevents the PCI core from assigning resources for the Apex BARs because __dev_sort_resources() ignores classless devices, host bridges, and IOAPICs.

But on some architectures, firmware does *not* assign BARs, and since the PCI core didn't do it either, the Apex device didn't work correctly: apex 0000:01:00.0: can't enable device: BAR 0 [mem 0x00000000-0x00003fff 64bit pref] not claimed apex 0000:01:00.0: error enabling PCI device f390d08d8b87 ("staging: gasket: apex: fixup undefined PCI class") added a quirk to fix the class code, but it was in the apex driver, and if the driver was built as a module, it was too late to help. Move the quirk to the PCI core, where it will always run early enough that the PCI core will assign resources if necessary.

When siw_fastreg_mr() returns, "mem" becomes invalid, so the refcount should be decreased to keep refcount balanced. The issue happens in one error path of siw_fastreg_mr(). When "base_mr" equals to NULL but "mem" is not NULL, the function forgets to decrease the refcnt increased by siw_mem_id2obj() and causes a refcnt leak.

However, if L1 has not set the 'monitor trap flag' VM-execution control, KVM fails to reflect the subsequent MTF VM-exit into L1. Fix this by consulting the VM-entry interruption-information field of vmcs12 to determine if L1 has injected the MTF VM-exit.

The register region of this controller is much smaller, and there is no other hardware register interleaved. There is no good reason to split it into two regions. Just use a single, contiguous register region. While I am here, I made the 'dma-channels' property mandatory because otherwise there is no way to determine the number of the channels.

The firmware definition was changed to a fixed 32 byte compiler description string. This length covers all released firmware binaries and thus only a minor ABI change is needed. As the same structure is used in IPC messages between driver and firmware, the kernel needs to be aligned to firmware change.

Host ---> Proc----> Selector0 --> Buf0 ---- > DAI Playback | v Buf1 | v Host <---------------Selector1 <----- Buf2 <----- Echo Ref DAI In the example above we two host PCMs that can be independently started/stopped thereby causing buf1 to either underrun or overrun (and stop the pipelines). Buf1 should be permitted to underrun or overrun without invoking pipeline XRUN logic and should over write oldest data (for overrun) and readback 0s (for underrun). 2 flags have been added for use during buffer instantiation: SOF_BUF_OVERRUN_PERMITTED and SOF_BUF_UNDERRUN_PERMITTED, along with struct sof_ipc_buffer member fields: flags and reserved. Flags field is supposed to hold the above-mentioned flags to allow some control over XRUN behaviour. Also added reserved field to the structure in case it comes in handy some time in the future. This is an incremental ABI change as the new fields are ignored by older versions of the firmware.

Here this kind of combination is called a "set". Lately we've seen more complex widget definitions with multiple identical sets of tuple arrays. One example is the dmic pdm configuration, which is currently handled as a special case in token parsing. This is not scalable for other components with multiple sets. So add a new function sof_parse_token_sets, which can be used to parse multiple sets. This function defines the number of sets and an offset to copy the tokens to correct positions in the destination ipc struct. Old sof_parse_token function will be a special case of calling sof_parse_token_sets to parse 1 set with offset 0. Finally modify the dmic dai link loading to use the new sof_parse_array_sets to load multiple pdm configs.

This prevents a matching of a capable hardware endpoint during configuration. Below is the minimum recommended HW configuration to support a particular endpoint setup from the databook: For OUT endpoints, the databook recommended the minimum RxFIFO size to be at least 3x MaxPacketSize + 3x setup packets size (8 bytes each) + clock crossing margin (16 bytes). For IN endpoints, the databook recommended the minimum TxFIFO size to be at least 3x MaxPacketSize for endpoints that support burst. If the endpoint doesn't support burst or when the device is operating in USB 2.0 mode, a minimum TxFIFO size of 2x MaxPacketSize is recommended. Base on these recommendations, we can calculate the MaxPacketSize limit of each endpoint. This patch revises the IN endpoint MaxPacketSize limit and also sets the MaxPacketSize limit for OUT endpoints.

When that happens, usb_sg_cancel() may continue to access the transfer's URBs after usb_sg_wait() has freed them. The bug is caused by the fact that usb_sg_cancel() does not take any sort of reference to the transfer, and so there is nothing to prevent the URBs from being deallocated while the routine is trying to use them. The fix is to take such a reference by incrementing the transfer's io->count field while the cancellation is in progres and decrementing it afterward. The transfer's URBs are not deallocated until io->complete is triggered, which happens when io->count reaches zero.

The spec at https://www.intel.com/content/dam/www/public/us/en/documents/technical-specifications/extensible-host-controler-interface-usb-xhci.pdf says in section "4.5.1 Device Context Index" that the Context Index, also known as Endpoint ID according to section "1.6 Terms and Abbreviations", is normally computed as `DCI = (Endpoint Number * 2) + Direction`, which matches the current definitions of XDBC_EPID_OUT and XDBC_EPID_IN. However, the numbering in a Debug Capability Context data structure is supposed to be different: Section "7.6.3.2 Endpoint Contexts and Transfer Rings" explains that a Debug Capability Context data structure has the endpoints mapped to indices 0 and 1. Change XDBC_EPID_OUT/XDBC_EPID_IN to the spec-compliant values, add XDBC_EPID_OUT_INTEL/XDBC_EPID_IN_INTEL with Intel's incorrect values, and let xdbc_handle_tx_event() handle both. I have verified that with this patch applied, the USB3 early console works on both an Intel and an AMD machine.

The referenced commit broke pen and touch input for a variety of devices such as the Cintiq Pro 32. Affected devices may appear to work normally for a short amount of time, but eventually loose track of actual touch state and can leave touch arbitration enabled which prevents the pen from working. The commit is not itself required for any currently-available Bluetooth device, and so we revert it to correct the behavior of broken devices. This breakage occurs due to a mismatch between the order of collections and the order of usages on some devices. This commit tries to read the contact count before processing events, but will fail if the contact count does not occur prior to the first logical finger collection. This is the case for devices like the Cintiq Pro 32 which place the contact count at the very end of the report. Without the contact count set, touches will only be partially processed. The `wacom_wac_finger_slot` function will not open any slots since the number of contacts seen is greater than the expectation of 0, but we will still end up calling `input_mt_sync_frame` for each finger anyway. This can cause problems for userspace separate from the issue currently taking place in the kernel. Only once all of the individual finger collections have been processed do we finally get to the enclosing collection which contains the contact count. The value ends up being used for the *next* report, however. This delayed use of the contact count can cause the driver to loose track of the actual touch state and believe that there are contacts down when there aren't. This leaves touch arbitration enabled and prevents the pen from working. It can also cause userspace to incorrectly treat single- finger input as gestures.

However, when we reload the target, there could be another active instance running on the same device. This is the sequence of operations when doing a reload: 1. construct new target 2. suspend old target 3. resume new target 4. destroy old target Metadata that were written by the old target between steps 1 and 2 would not be visible by the new target. Fix the data corruption by loading the metadata in the resume handler. Also, validate block_size is at least as large as both the devices' logical block size and only read 1 block from the metadata during target constructor -- no need to read entirety of metadata now that it is done during resume.

Fix this by having that call be reached through a different label. Additionally, if qcom_add_sysmon_subdev() returns an error, the subdevs that had already been added will not be properly removed. Fix this by having the added subdevs (including the IPA notify one) be removed in this case. Finally, arrange for the sysmon subdev to be removed before the rest in the event rproc_add() returns an error. Have cleanup activity done in q6v5_remove() be done in the reverse order they are set up in q6v5_probe() (the same order they're done in the q6v5_probe() error path). Use a local variable for the remoteproc pointer, which is used repeatedly. Remove errant semicolons at the end of two function blocks.

Such backchannel Calls are aggressively retried until the client reconnects. Backchannel Calls should use RPC_TASK_NOCONNECT rather than RPC_TASK_SOFTCONN. If there is no forward connection, the server is not capable of establishing a connection back to the client, thus that backchannel request should fail before the server attempts to send it. Commit 58255a4e3ce5 ("NFSD: NFSv4 callback client should use RPC_TASK_SOFTCONN") was merged several years before RPC_TASK_NOCONNECT was available. Because setup_callback_client() explicitly sets NOPING, the NFSv4.0 callback connection depends on the first callback RPC to initiate a connection to the client. Thus NFSv4.0 needs to continue to use RPC_TASK_SOFTCONN.

Without this fix, each RPC whose Reply cannot be sent leaks one svc_rdma_recv_ctxt. This is a 2.5KB structure, a 4KB DMA-mapped Receive buffer, and any pages that might be part of the Reply message. The leak is infrequent unless the network fabric is unreliable or Kerberos is in use, as GSS sequence window overruns, which result in connection loss, are more common on fast transports.

On top of that, set SHIM registers to their recommended defaults during D0 and D3 proceduces as HW does not reset registers for us. Connected to: [alsa-devel][BUG] bdw-rt5650 DSP boot timeout https://mailman.alsa-project.org/pipermail/alsa-devel/2019-July/153098.html Github issue ticket reference: https://github.com/thesofproject/linux/pull/1842 Tested on: - BDW-Y RVP with rt286 - SAMUS with rt5677 Proposed solution (both in July 2019 and on github): 'Revert "ASoC: Intel: Work around to fix HW d3 potential crash issue"' is NAKed as it only covers the problem up and actually brings back the undefined behavior: some registers (e.g.: APLLSE) are describing LPT offsets rather than WPT ones. In consequence, during power-transitions driver issues incorrect writes and leaves the regs of interest alone. Existing patch - the non-revert - does not resolve the HW D3 issue at all as it ignores the recommended sequence and does not initialize hardware registers as expected. And thus, leaving things as are is also unacceptable.

At each clock cycle, the value of the addend register is added to the accumulator. Currently, we use 20ns = 1e09ns / 50MHz as this value whatever the frequency of the ptp clock actually is. The adjustment is then done on the addend register, only incrementing every X clock cycles X being the ratio between 50MHz and ptp_clock_rate (addend = 2^32 * 50MHz/ptp_clock_rate). This causes the following issues : - In case the frequency of the ptp clock is inferior or equal to 50MHz, the addend value calculation will overflow and the default addend value will be set to 0, causing the clock to not work at all. (For instance, for ptp_clock_rate = 50MHz, addend = 2^32). - The resolution of the timestamping clock is limited to 20ns while it is not needed, thus limiting the accuracy of the timestamping to 20ns. Fix this by setting sub-second increment to 2e09ns / ptp_clock_rate. It will allow to reach the minimum possible frequency for ptp_clk_ref, which is 5MHz for GMII 1000Mps Full-Duplex by setting the sub-second-increment to a higher value. For instance, for 25MHz, it gives ssinc = 80ns and default_addend = 2^31. It will also allow to use a lower value for sub-second-increment, thus improving the timestamping accuracy with frequencies higher than 100MHz, for instance, for 200MHz, ssinc = 10ns and default_addend = 2^31. v1->v2: - Remove modifications to the calculation of default addend, which broke compatibility with clock frequencies for which 2000000000 / ptp_clk_freq is not an integer. - Modify description according to discussions.

We currently run in an overflow when assigning the value 16 to it. According to the standard a value of 16 can be interpreted as a full elided address which isn't possible to set as compression value. A reason why this cannot be set is that the current ipv6 header destination address should never show up inside the segments of the rpl header. In this case we run in a overflow and the address will have no compression at all. Means cmpri or compre is set to 0. As we handle cmpri and cmpre sometimes as unsigned char or 4 bit value inside the rpl header the current behaviour ends in an invalid header format. This patch simple use the best compression method if we ever run into the case that the destination address is showed up inside the rpl segments. We avoid the overflow handling and the rpl header is still valid, even when we have the destination address inside the rpl segments. Signed-off-by: Alexander Aring Signed-off-by: David S.

Since the headphone jack can only be used for audio when in `headphone out` position this commit changes the headphone detect GPIO logic to be correct for that case rather than for the debug UART.

Otherwise it is possible that it was still set from a previous capture. If that is the case the interrupt would fire immediately even though no conversion has been done yet and stale data is being read from the device. The old code only clears the interrupt if the interrupt was previously unmasked. Which does not make much sense since the interrupt is always masked at this point and in addition masking the interrupt does not clear the interrupt from the status register. So the clearing needs to be done unconditionally.

Depending on the mode it is operating in either one or both of them are used. The device manual calls this continuous (one ADC) and simultaneous (both ADCs) mode. The meaning of the sequencing register for the aux channels changes depending on the mode. In continuous mode each bit corresponds to one of the 16 aux channels. And the single ADC will convert them one by one in order. In simultaneous mode the aux channels are split into two groups the first 8 channels are assigned to the first ADC and the other 8 channels to the second ADC. The upper 8 bits of the sequencing register are unused and the lower 8 bits control both ADCs. This means a bit needs to be set if either the corresponding channel from the first group or the second group (or both) are set. Currently the driver does not have the special handling required for simultaneous mode. Add it.

Unfortunately the hardware does not have a FIFO, which means it generates an interrupt for each conversion sequence. At one 1MSPS this creates an interrupt storm that causes the system to soft-lock. For this reason the driver limits the maximum samplerate to 150kSPS. Currently this check is only done when setting a new samplerate. But it is also possible that the initial samplerate configured in the FPGA bitstream exceeds the limit. In this case when starting to capture data without first changing the samplerate the system can overload. To prevent this check the currently configured samplerate in the probe function and reduce it to the maximum if necessary.

After looking into codes, I found this issue is still due to the union definition: union { /* * Only commands that never go async can use the below fields, * obviously. Right now only IORING_OP_POLL_ADD uses them, and * async armed poll handlers for regular commands. The latter * restore the work, if needed. */ struct { struct callback_head task_work; struct hlist_node hash_node; struct async_poll *apoll; }; struct io_wq_work work; }; When task_work_run has multiple work to execute, the work that calls io_poll_remove_all() will do req->work restore for non-poll request always, but indeed if a non-poll request has been added to a new callback_head, subsequent callback will call io_async_task_func() to handle this request, that means we should not do the restore work for such non-poll request. Meanwhile in io_async_task_func(), we should drop submit ref when req has been canceled. Fix both issues.

This uncovered that the ->card_busy() op in the Meson SDIO driver was never working right: while polling the busy status with ->card_busy() meson_mx_mmc_card_busy() reads only one of the two MESON_MX_SDIO_IRQC register values 0x1f001f10 or 0x1f003f10. This translates to "three out of four DAT lines are HIGH" and "all four DAT lines are HIGH", which is interpreted as "the card is busy". It turns out that no situation can be observed where all four DAT lines are LOW, meaning the card is not busy anymore. Upon further research the 3.10 vendor driver for this controller does not implement the ->card_busy() op. Remove the ->card_busy() op from the meson-mx-sdio driver since it is not working. At the time of writing this patch it is not clear what's needed to make the ->card_busy() implementation work with this specific controller hardware. For all use-cases which have previously worked the MMC_CAP_WAIT_WHILE_BUSY flag is now taking over, even if we don't have a ->card_busy() op anymore.

In the case of cqhci we might report "CQE stuck on" even if it wasn't stuck on. You'd just need this sequence of events to happen in cqhci_off(): 1. Call ktime_get(). 2. Something happens to interrupt the CPU for > 100 us (context switch or interrupt). 3. Check time and; set "timed_out" to true since > 100 us. 4. Read CQHCI_CTL. 5. Both "reg & CQHCI_HALT" and "timed_out" are true, so break. 6. Since "timed_out" is true, falsely print the error message. Rather than fixing the polling loop, use readx_poll_timeout() like many people do. This has been time tested to handle the corner cases.

Tsirkin" Date: Mon, 6 Apr 2020 08:12:47 -0400 Subject: vhost: disable for OABI vhost is currently broken on the some ARM configs. The reason is that the ring element addresses are passed between components with different alignments assumptions. Thus, if guest selects a pointer and host then gets and dereferences it, then alignment assumed by the host's compiler might be greater than the actual alignment of the pointer. compiler on the host from assuming pointer is aligned. This actually triggers on ARM with -mabi=apcs-gnu - which is a deprecated configuration. With this OABI, compiler assumes that all structures are 4 byte aligned - which is stronger than virtio guarantees for available and used rings, which are merely 2 bytes. Thus a guest without -mabi=apcs-gnu running on top of host with -mabi=apcs-gnu will be broken. The correct fix is to force alignment of structures - however that is an intrusive fix that's best deferred until the next release. We didn't previously support such ancient systems at all - this surfaced after vdpa support prompted removing dependency of vhost on VIRTULIZATION. So for now, let's just add something along the lines of depends on !ARM || AEABI to the virtio Kconfig declaration, and add a comment that it has to do with struct member alignment. Note: we can't make VHOST and VHOST_RING themselves have a dependency since these are selected. Add a new symbol for that. We should be able to drop this dependency down the road.

Specifically my writes seem to be happening at ~15 MB/s and I've got ~4 GB of RAM in my system that can be used for buffering. To write 4 GB of buffer to disk thus takes ~4000 MB / ~15 MB/s = ~267 seconds. The 267 second number is a problem because in __blkdev_put() we call sync_blockdev() while holding the bd_mutex. Any other callers who want the bd_mutex will be blocked for the whole time. The problem is made worse because I believe blkdev_put() specifically tells other tasks (namely udev) to go try to access the device at right around the same time we're going to hold the mutex for a long time. Putting some traces around this (after disabling the hung task detector), I could confirm: dd: 437.608600: __blkdev_put() right before sync_blockdev() for sdb udevd: 437.623901: blkdev_open() right before blkdev_get() for sdb dd: 661.468451: __blkdev_put() right after sync_blockdev() for sdb udevd: 663.820426: blkdev_open() right after blkdev_get() for sdb A simple fix for this is to realize that sync_blockdev() works fine if you're not holding the mutex. Also, it's not the end of the world if you sync a little early (though it can have performance impacts). Thus we can make a guess that we're going to need to do the sync and then do it without holding the mutex. We still do one last sync with the mutex but it should be much, much faster. With this, my hung task warnings for my test case are gone.

So if i915 takes the BIOS state and don't do a modeset any following link retraing will fail. In the case that i915 needs to do a modeset, the DDI disable sequence will write to a wrong register not disabling DP 'Transport Enable' in DP_TP_CTL, making a HDMI modeset in the same port/transcoder to not light up the monitor. So here for GENs older than 12, that have those registers fixed at port offset range it is loading at encoder/port init while for GEN12 it will keep setting it at encoder pre_enable() and during HW state readout.

If the mode module is not inserted, it calls the request_module(). In the request_module(), it creates a child process, which is the "modprobe" process and waits for the done of the child process. At this point, the following locks were used. down_read(&cb_lock()); by genl_rcv() genl_lock(); by genl_rcv_msc() rtnl_lock(); by team_nl_cmd_options_set() mutex_lock(&team->lock); by team_nl_team_get() Concurrently, the team module could be removed by rmmod or "modprobe -r" The __exit function of team module is team_module_exit(), which calls team_nl_fini() and it tries to acquire following locks. down_write(&cb_lock); genl_lock(); Because of the genl_lock() and cb_lock, this process can't be finished earlier than request_module() routine. The problem secenario. CPU0 CPU1 team_mode_get request_module() modprobe -r team_mode_roundrobin team <--(B) modprobe team <--(A) team_mode_roundrobin By request_module(), the "modprobe team_mode_roundrobin" command will be executed. At this point, the modprobe process will decide that the team module should be inserted before team_mode_roundrobin. Because the team module is being removed. By the module infrastructure, the same module insert/remove operations can't be executed concurrently. So, (A) waits for (B) but (B) also waits for (A) because of locks. So that the hang occurs at this point. Test commands: while : do teamd -d & killall teamd & modprobe -rv team_mode_roundrobin & done The approach of this patch is to hold the reference count of the team module if the team module is compiled as a module. If the reference count of the team module is not zero while request_module() is being called, the team module will not be removed at that moment. So that the above scenario could not occur.

Looking at mlx5_fw_tracer_save_trace(), it is actually the driver itself that copies the debug data into the trace array and there is no need for the allocation to be contiguous in physical memory. We can therefor use kvzalloc() instead of kzalloc() and get rid of the large contiguous allcoation.

When the command "cat /sys/class/net/NIC/statistics/tx_packets" is run, before updating 802_3 data layout with ppcnt register, the monitor counters are tested. The test result will decide the 802_3 data layout is updated or not. Actually the monitor counters do not support to monitor rx/tx stats of 802_3 in switchdev mode. So the rx/tx counters change will not trigger monitor counters. So the 802_3 data layout will not be updated in ppcnt register.

Because that case wasn't checked for, we could misinterpret the non-present PTE as being a cache-inhibited PTE. That could mismatch with the corresponding hash PTE, which would cause the function to fail with -EFAULT a little further down. That would propagate up to the KVM_RUN ioctl() generally causing the KVM userspace (usually qemu) to fall over. This addresses the problem by catching that case and returning to the guest instead. For completeness, this fixes the radix page fault handler in the same way. For radix this didn't cause any obvious misbehaviour, because we ended up putting the non-present PTE into the guest's partition-scoped page tables, leading immediately to another hypervisor data/instruction storage interrupt, which would go through the page fault path again and fix things up.

However, since the placeholder value -1 is passed as `value_regno`, check_stack_read() can only return a binary decision and can't return the type of the value that was read. The intent here is to verify whether the value read from the stack slot may be used as a SCALAR_VALUE; but since check_stack_read() doesn't check the type, and the type information is lost when check_stack_read() returns, this is not enforced, and a malicious user can abuse XADD to leak spilled kernel pointers. Fix it by letting check_stack_read() verify that the value is usable as a SCALAR_VALUE if no type information is passed to the caller. To be able to use __is_pointer_value() in check_stack_read(), move it up. Fix up the expected unprivileged error message for a BPF selftest that, until now, assumed that unprivileged users can use XADD on stack-spilled pointers. This also gives us a test for the behavior introduced in this patch for free. In theory, this could also be fixed by forbidding XADD on stack spills entirely, since XADD is a locked operation (for operations on memory with concurrency) and there can't be any concurrency on the BPF stack; but Alexei has said that he wants to keep XADD on stack slots working to avoid changes to the test suite [1].

The current implementation for BPF_STX BPF_B in emit_stx saves one REX byte when the operands can be encoded using Mod-R/M alone. The lower 8 bits of registers %rax, %rbx, %rcx, and %rdx can be accessed without using a REX prefix via %al, %bl, %cl, and %dl, respectively. Other registers, (e.g., %rsi, %rdi, %rbp, %rsp) require a REX prefix to use their 8-bit equivalents (%sil, %dil, %bpl, %spl). The current code checks if the source for BPF_STX BPF_B is BPF_REG_1 or BPF_REG_2 (which map to %rdi and %rsi), in which case it emits the required REX prefix. However, it misses the case when the source is BPF_REG_FP (mapped to %rbp). The result is that BPF_STX BPF_B with BPF_REG_FP as the source operand will read from register %ch instead of the correct %bpl. This patch fixes the problem by fixing and refactoring the check on which registers need the extra REX byte. Since no BPF registers map to %rsp, there is no need to handle %spl.

Per the devicetree spec cache-line-size is only needed if it differs from the block size. Originally the code would fallback from block size to line size. An error message was printed if both properties were missing. Later the code was refactored to use clearer names and logic but it inadvertently made line size a required property, meaning on systems without a line size property we fall back to the default from the cputable. On powernv (OPAL) platforms, since the introduction of device tree CPU features (5a61ef74f269 ("powerpc/64s: Support new device tree binding for discovering CPU features")), that has led to the wrong value being used, as the fallback value is incorrect for Power8/Power9 CPUs. The incorrect values flow through to the VDSO and also to the sysconf values, SC_LEVEL1_ICACHE_LINESIZE etc. Fixes: bd067f83b084 ("powerpc/64: Fix naming of cache block vs. cache line") Cc: stable@vger.kernel.org # v4.11+ Signed-off-by: Chris Packham Reported-by: Qian Cai [mpe: Add even more detail to change log] Signed-off-by: Michael Ellerman Link: https://lore.kernel.org/r/20200416221908.7886-1-chris.packham@alliedtelesis.co.nz --- arch/powerpc/kernel/setup_64.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/arch/powerpc/kernel/setup_64.c b/arch/powerpc/kernel/setup_64.c index 438a9befce41..8105010b0e76 100644 --- a/arch/powerpc/kernel/setup_64.c +++ b/arch/powerpc/kernel/setup_64.c @@ -534,6 +534,8 @@ static bool __init parse_cache_info(struct device_node *np, lsizep = of_get_property(np, propnames[3], NULL); if (bsizep == NULL) bsizep = lsizep; + if (lsizep == NULL) + lsizep = bsizep; if (lsizep != NULL) lsize = be32_to_cpu(*lsizep); if (bsizep != NULL) -- cgit v1.2.3-59-g8ed1b From fd0c42c4dea54335967c5a86f15fc064235a2797 Mon Sep 17 00:00:00 2001 From: George Spelvin Date: Sun, 8 Mar 2020 09:44:59 -0400 Subject: batman-adv: fix batadv_nc_random_weight_tq and change to pseudorandom numbers, as this is a traffic dithering operation that doesn't need crypto-grade. The previous code operated in 4 steps: 1. Generate a random byte 0 <= rand_tq <= 255 2. Multiply it by BATADV_TQ_MAX_VALUE - tq 3. Divide by 255 (= BATADV_TQ_MAX_VALUE) 4. Return BATADV_TQ_MAX_VALUE - rand_tq This would apperar to scale (BATADV_TQ_MAX_VALUE - tq) by a random value between 0/255 and 255/255. But! The intermediate value between steps 3 and 4 is stored in a u8 variable. So it's truncated, and most of the time, is less than 255, after which the division produces 0. Specifically, if tq is odd, the product is always even, and can never be 255. If tq is even, there's exactly one random byte value that will produce a product byte of 255. Thus, the return value is 255 (511/512 of the time) or 254 (1/512 of the time). If we assume that the truncation is a bug, and the code is meant to scale the input, a simpler way of looking at it is that it's returning a random value between tq and BATADV_TQ_MAX_VALUE, inclusive. Well, we have an optimized function for doing just that.

So far, the VP assist page is used by hv_apic_eoi_write(), and is also used in the case of nested virtualization (running KVM atop Hyper-V). For hv_apic_eoi_write(), when the page is not properly re-enabled, hvp->apic_assist is always 0, so the HV_X64_MSR_EOI MSR is always written. This is not ideal with respect to performance, but Hyper-V can still correctly handle this according to the Hyper-V spec; nevertheless, Linux still must update the Hyper-V hypervisor with the correct VP assist page to prevent Hyper-V from writing to the stale page, which causes guest memory corruption and consequently may have caused the hangs and triple faults seen during non-boot CPUs resume. Fix the issue by calling hv_cpu_die()/hv_cpu_init() in the syscore ops. Without the fix, hibernation can fail at a rate of 1/300 ~ 1/500. With the fix, hibernation can pass a long-haul test of 2000 runs. In the case of nested virtualization, disabling/reenabling the assist page upon hibernation may be unsafe if there are active L2 guests. It looks KVM should be enhanced to abort the hibernation request if there is any active L2 guest.

This seems to not have caused any issues right now, likely because the hardware no longer supports putting multiple entries into a single RB, and practically all of the entries should be smaller than 2k. Nevertheless, it's a bug, and we must advertise the right size to the device. Note that right now we can only tell it 2k vs. 4k, so for the cases where we have more, still use 4k. This needs to be fixed by the firmware first.

However, the firmware API and queue allocation code assumes that there are 32 queues, and if something actually attempts to use #31 this leads to a NULL-pointer dereference since it's not allocated. Fix this by limiting to 31 in the IWL_MVM_DQA_MAX_DATA_QUEUE, and also add some code to catch this earlier in the future, if the configuration changes perhaps.

On CPU1 thread 1 does e.g. strnlen_user(). That gets to old_fs = enable_sacf_uaccess(); len = strnlen_user_srst(src, size); and " la %2,0(%1)\n" " la %3,0(%0,%1)\n" " slgr %0,%0\n" " sacf 256\n" "0: srst %3,%2\n" in strnlen_user_srst(). At that point we are in secondary space mode, control register 1 points to kernel page table and instruction fetching happens via c1, rather than usual c13. Interrupts are not disabled, for obvious reasons. On CPU2 thread 2 does MAP_FIXED mmap(), forcing the upgrade of page table from 3-level to e.g. 4-level one. We'd allocated new top-level table, set it up and now we hit this: notify = 1; spin_unlock_bh(&mm->page_table_lock); } if (notify) on_each_cpu(__crst_table_upgrade, mm, 0); OK, we need to actually change over to use of new page table and we need that to happen in all threads that are currently running. Which happens to include the thread 1. IPI is delivered and we have static void __crst_table_upgrade(void *arg) { struct mm_struct *mm = arg; if (current->active_mm == mm) set_user_asce(mm); __tlb_flush_local(); } run on CPU1. That does static inline void set_user_asce(struct mm_struct *mm) { S390_lowcore.user_asce = mm->context.asce; OK, user page table address updated... __ctl_load(S390_lowcore.user_asce, 1, 1); ... and control register 1 set to it. clear_cpu_flag(CIF_ASCE_PRIMARY); } IPI is run in home space mode, so it's fine - insns are fetched using c13, which always points to kernel page table. But as soon as we return from the interrupt, previous PSW is restored, putting CPU1 back into secondary space mode, at which point we no longer get the kernel instructions from the kernel mapping.

This halted endpoint was not handled correctly by xhci driver as events on empty rings were all assumed to be spurious events. xhci driver refused to restart the ring with EP_HALTED flag set, so class driver was never informed the endpoint halted even if it queued new URBs. The host side of the endpoint needs to be reset, and dequeue pointer should be moved in order to clear the cached TRBs and resetart the endpoint. Small adjustments in finding the new dequeue pointer are needed to support the case of stall on an empty ring and unknown current TD.

When we initialize the boot task's APIAKey in boot_init_stack_canary() via ptrauth_keys_switch_kernel() we miss the necessary ISB, and so there is a window where instructions are not guaranteed to use the new APIAKey value. This has been observed to result in boot-time crashes where PACIASP and AUTIASP within a function used a mixture of the old and new key values. Fix this by having ptrauth_keys_switch_kernel() synchronize the new key value with an ISB. At the same time, __ptrauth_key_install() is renamed to __ptrauth_key_install_nosync() so that it is obvious that this performs no synchronization itself.

This happens because do_notify_parent is called from the last thread to exit in a process after that thread has been reaped. The bigger issue is that do_notify_parent can be called from any process that manages to wait on a thread of a multi-threaded process from wait_task_zombie. So any logic based upon current for do_notify_parent is just nonsense, as current can be pretty much anything. So change do_notify_parent to call __send_signal directly. Inspecting the code it appears this problem has existed since the pid namespace support started handling this case in 2.6.30. This fix only backports to 7a0cf094944e ("signal: Correct namespace fixups of si_pid and si_uid") where the problem logic was moved out of __send_signal and into send_signal.

This bring a problem that EASRC accept format directly from devicetree, but ASRC accept width from devicetree. In order to align with new ESARC, we add new property fsl,asrc-format. The fsl,asrc-format can replace the fsl,asrc-width, then driver can accept format from devicetree, don't need to convert it to format through width.

Content-Transfer-Encoding: 8bit Systemtap 4.2 is unable to correctly interpret the "u32 (*missed_ppm)[2]" argument of the iocost_ioc_vrate_adj trace entry defined in include/trace/events/iocost.h leading to the following error: /tmp/stapAcz0G0/stap_c89c58b83cea1724e26395efa9ed4939_6321_aux_6.c:78:8: error: expected ‘;’, ‘,’ or ‘)’ before ‘*’ token , u32[]* __tracepoint_arg_missed_ppm That argument type is indeed rather complex and hard to read. Looking at block/blk-iocost.c. It is just a 2-entry u32 array. By simplifying the argument to a simple "u32 *missed_ppm" and adjusting the trace entry accordingly, the compilation error was gone.

but hugetlbfs_file_setup() calls user_shm_lock() with interrupts enabled, and might be interrupted by a writeback endio wanting xa_lock on i_pages. This may not risk an actual deadlock, since shmem inodes do not take part in writeback accounting, but there are several easy ways to avoid it. Requiring interrupts disabled for shmlock_user_lock would be easy, but it's a high-level global lock for which that seems inappropriate. Instead, recall that the use of info->lock to guard info->flags in shmem_lock() dates from pre-3.1 days, when races with SHMEM_PAGEIN and SHMEM_TRUNCATE could occur: nowadays it serves no purpose, the only flag added or removed is VM_LOCKED itself, and calls to shmem_lock() an inode are already serialized by the caller. Take info->lock out of the chain and the possibility of deadlock or lockdep warning goes away.

NETDEV_UNREGISTER of dummy1 notification is sent to macvlan module. 3. ->dellink() of macvlan1 is called. 4. NETDEV_UNREGISTER of macvlan1 notification is sent to bond module. 5. __bond_release_one() is called and it internally calls dev_set_mac_address(). 6. dev_set_mac_address() calls the ->ndo_set_mac_address() of macvlan1, which is macvlan_set_mac_address(). 7. macvlan_set_mac_address() calls the dev_set_mac_address() with dummy1. 8. NETDEV_CHANGEADDR of dummy1 is sent to macvlan module. 9. In the macvlan_device_event(), it calls list_first_entry_or_null(). At this point, dummy1 and macvlan1 were removed. So, list_first_entry_or_null() will return NULL.

However, from reading the code, I think the APIs don't really work for aacraid, because, in the resume path of hibernation, when aac_suspend() -> scsi_host_block() is called, scsi_device_quiesce() has set the state to SDEV_QUIESCE, so aac_suspend() -> scsi_host_block() returns -EINVAL.

This is done to avoid changing the value for different boards. Putting aside the merits of this approach, it is clear the eMMC's mask of supported driver strengths is more reliable than the value provided by BIOS. Add validation accordingly.

This means that if such an interrupt lives in a List Register on another CPU, we fail to obsertve the latest active state for this interrupt. In order to remedy this, stop all the other vcpus so that they exit and we can observe the most recent value for the state. This is similar to what we are doing for the write side of the same registers, and results in new MMIO handlers for userspace (which do not need to stop the guest, as it is supposed to be stopped already).

This change fixes a bug by which the key was enabled every time cpu0 is started, even as a secondary CPU during cpu hotplug. Secondary CPUs are started from the idle thread: setting a static key from there means acquiring a lock and may result in sleeping in the idle task, causing CPU lockup. Another consequence of this change is that init_counter_refs() is now called on each CPU correctly; previously the function on_each_cpu() was used, but it was called at boot when the only online cpu is cpu0.

It also checks whether the task has a RT policy, and sets its uclamp.min to 1024 accordingly. However, during reset-on-fork, the task's policy is lowered to SCHED_NORMAL right after, hence leading to an erroneous uclamp.min setting for the new task if it was forked from RT. Fix this by removing the unnecessary check on rt_task() in uclamp_fork() as this doesn't make sense if the reset-on-fork flag is set.

If that tcon is used multiple times e.g. 2 mounts using it with different prefixpath, each will need a different dfs_path but there is only one tcon. The other solution would be to split the tcon in 2 tcons during failover but that is much harder. tcons could not be shared with DFS in cifs.ko because in a DFS namespace like: //domain/dfsroot -> /serverA/dfsroot, /serverB/dfsroot //serverA/dfsroot/link -> /serverA/target1/aa/bb //serverA/dfsroot/link2 -> /serverA/target1/cc/dd you can see that link and link2 are two DFS links that both resolve to the same target share (/serverA/target1), so cifs.ko will only contain a single tcon for both link and link2. The problem with that is, if we (auto)mount "link" and "link2", cifs.ko will only contain a single tcon for both DFS links so we couldn't perform failover or refresh the DFS cache for both links because tcon->dfs_path was set to either "link" or "link2", but not both -- which is wrong.

I believe we should not impose any include order restriction. We often sort include directives alphabetically, but it is just coding style convention. Technically, we can include header files in any order by making every header self-contained. Currently, arch-specific MODULE_ARCH_VERMAGIC is defined in , which is not included from .

With this, and will be orthogonal, and the location of MODULE_ARCH_VERMAGIC definitions will be consistent. For arc and ia64, MODULE_PROC_FAMILY is only used for defining MODULE_ARCH_VERMAGIC. I squashed it. For hexagon, nds32, and xtensa, I removed entirely because they contained nothing but MODULE_ARCH_VERMAGIC definition. Kbuild will automatically generate at build-time, wrapping .

This bundling was broken by commit 4ff40b86262b ("sctp: set chunk transport correctly when it's a new asoc"), which assigns a transport for the COOKIE-ACK, but not for the SHUTDOWN. Fix this by passing a reference to the COOKIE-ACK chunk as an argument to sctp_sf_do_9_2_start_shutdown() and onward to sctp_make_shutdown(). This way the SHUTDOWN chunk is assigned the same transport as the COOKIE-ACK chunk, which allows them to be bundled. In sctp_sf_do_9_2_start_shutdown(), the void *arg parameter was previously unused. Now that we're taking it into use, it must be a valid pointer to a chunk, or NULL. There is only one call site where it's not, in sctp_sf_autoclose_timer_expire(). Fix that too.

Since we do not clear all the mptcp sock RX options in a socket free/alloc cycle, we can end-up with a stray data_fin value while parsing e.g. MPC packets. That would lead to mapping data corruption and will trigger a few WARN_ON() in the RX path. Instead of adding a costly memset(), fetch the data_fin flag only for DSS packets - when we always explicitly initialize such bit at option parsing time.

The problem it tried to fix was that if a connect-change event occurred while the system was asleep (such as a device disconnecting itself from the bus when it is suspended and then reconnecting when it resumes) requiring a reset-resume during the system wakeup transition, the hub port's change_bit entry would remain set afterward. This would cause the hub driver to believe another connect-change event had occurred after the reset-resume, which was wrong and would lead the driver to send unnecessary requests to the device (which could interfere with a firmware update). The commit tried to fix this by not setting the change_bit during the wakeup. But this was the wrong thing to do; it means that when a device is unplugged while the system is asleep, the hub driver doesn't realize anything has happened: The change_bit flag which would tell it to handle the disconnect event is clear. The commit needs to be reverted and the problem fixed in a different way. Fortunately an alternative solution was noted in the commit's Changelog: We can continue to set the change_bit entry in hub_activate() but then clear it when a reset-resume occurs. That way the the hub driver will see the change_bit when a device is disconnected but won't see it when the device is still present. That's what this patch does.

Instead of using the "new" enumeration scheme first and switching to the "old" scheme if that doesn't work, we start with the "old" scheme. In theory this is better because the "old" scheme is slightly faster -- it involves resetting the device only once instead of twice. However, for a long time Windows used only the "new" scheme. Zeng Tao said that Windows 8 and later use the "old" scheme for high-speed devices, but apparently there are some devices that don't like it. William Bader reports that the Ricoh webcam built into his Sony Vaio laptop not only doesn't enumerate under the "old" scheme, it gets hung up so badly that it won't then enumerate under the "new" scheme! Only a cold reset will fix it. Therefore we will revert the commit and go back to trying the "new" scheme first for high-speed devices.

This can be triggered from user space. Since there is no point having a physically contiguous buffer here, let's avoid the above issue as well as reducing pressure on high order allocations by using vmalloc() instead.

To prove this theory, Andre suggested to use "clk_ignore_unused" in kernel commnd line and it worked (Kernel happily lands into RAMFS world :)).

Each member has 8 submembers. * we can have more than 4 (PCI) boards, i.e. [board] can be OOB * line is not modulo-ed by anything, so the first line on the second board can be 4, on the 3rd 12 or alike (depending on previously registered boards). It's zero only on the first line of the first board. So even [line] can be OOB, quite soon (with the 2nd registered board already). This code is broken for ages, so just avoid the OOB accesses and don't try to fix it as we would need to find out the correct line number. Use the default: RS232, if we are out. Generally, if anyone needs to set the interface types, a module parameter is past the last thing that should be used for this purpose. The parameters' description says it's for ISA cards anyway.

Since the tcs_cmd structures passed to this function aren't zero-initialized, then we're left with random wait values. This results in waiting for completion for more commands than is necessary, depending on what's on the stack at the time. Removing the unnecessary if-condition fixes this, but add an explicit memset of the tcs_cmd structure as well to ensure predictable behavior if more tcs_cmd members are added in the future.

This is because we were doing IO after we had stopped all of the worker threads, because we do the log tree cleanup on roots at drop time. Cleaning up the log tree will always need to do reads if we happened to have evicted the blocks from memory. Because of this simply add a helper to btrfs_cleanup_transaction() that will go through and drop all of the log roots. This gets run before we do the close_ctree() work, and thus we are allowed to do any reads that we would need.

This order of checking for errors reflects more accuratly the behavior of physical zoned devices. Furthermore, the write pointer position of the target zone should be incremented only and only if no errors are reported by badblocks and memory backing handling. To fix this, introduce the small helper function null_process_cmd() which execute null_handle_badblocks() and null_handle_memory_backed() and use this function in null_zone_write() to correctly handle write requests to zoned null devices depending on the type and state of the write target zone. Also call this function in null_handle_zoned() to process read requests to zoned null devices. null_process_cmd() is called directly from null_handle_cmd() for regular null devices, resulting in no functional change for these type of devices. To have symmetric names, the function null_handle_zoned() is renamed to null_process_zoned_cmd().

This fixes a bug where attempting to do VFIO_IOMMU_MAP_DMA on an arbitrary PFNMAP'd region of memory calculates garbage for the PFN. Hilariously, this only got detected because the first "PFN" calculated by vaddr_get_pfn() is PFN 0 (vma->vm_pgoff==0), and iommu_iova_to_phys() uses PA==0 as an error, which triggers a WARN in vfio_unmap_unpin() because the translation "failed". PFN 0 is now unconditionally reserved on x86 in order to mitigate L1TF, which causes is_invalid_reserved_pfn() to return true and in turns results in vaddr_get_pfn() returning success for PFN 0. Eventually the bogus calculation runs into PFNs that aren't reserved and leads to failure in vfio_pin_map_dma(). The subsequent call to vfio_remove_dma() attempts to unmap PFN 0 and WARNs.

When x25_lapb_receive_frame() returns, local variable "nb" becomes invalid, so the refcount should be decreased to keep refcount balanced. The reference counting issue happens in one path of x25_lapb_receive_frame(). When pskb_may_pull() returns false, the function forgets to decrease the refcnt increased by x25_get_neigh(), causing a refcnt leak. Fix this issue by calling x25_neigh_put() when pskb_may_pull() returns false.

We noticed that this issue is related to bad DCC metadata from user space which may generate hangs and consequently an underflow on HUBP. After taking a deep look at the code path we realized that after resume we try to restore the commit with the DCC enabled framebuffer but the framebuffer is no longer valid. [how] This problem was only reported on Raven based system and after suspend, for this reason, this commit adds a new parameter on fill_plane_dcc_attributes() to give the option of disabling DCC programmatically. In summary, for disabling DCC we first verify if is a Raven system and if it is in suspend; if both conditions are true we disable DCC temporarily, otherwise, it is enabled.

This is due to passing all the schema files on the command line to dt-mk-schema. It currently is only with out of tree builds and is intermittent depending on the file path lengths. Commit 2ba06cd8565b ("kbuild: Always validate DT binding examples") made hitting this proplem more likely since the example validation now always gets the full list of schemas. Fix this by passing the schema file list in a pipe and using xargs. We end up doing the find twice, but the time is insignificant compared to the dt-mk-schema time.

This is clearly a core dumping problem, but we've never fixed it the right way, and instead have the notion of "check that the mm is still ok" using mmget_still_valid() after getting the mmap_sem for writing in any situation where we're not the original VM thread. See commit 04f5866e41fb ("coredump: fix race condition between mmget_not_zero()/get_task_mm() and core dumping") for more background on this whole mmget_still_valid() thing. You might want to have a barf bag handy when you do. We're discussing just fixing this properly in the only remaining core dumping routines. But even if we do that, let's make do_madvise() do the right thing, and then when we fix core dumping, we can remove all these mmget_still_valid() checks.

This means that the first 3 bytes of the next instruction will be treated as the rest of the immediate, breaking the stream of instructions. This patch fixes the problem by instead emitting "xor dst_hi,dst_hi" to clear the upper 32 bits. This fixes the problem and is more efficient than using MOV to load a zero immediate. This bug may not be currently triggerable as BPF_REG_AX is the only register not stored on the stack and the verifier uses it in a limited way, and the verifier implements a zero-extension optimization. But the JIT should avoid emitting incorrect encodings regardless.

However, for freplace programs, the attach type was not propagated along with the verifier ops, so the expected_attach_type would always be zero for freplace programs. This in turn caused the verifier to sometimes make the wrong call for freplace programs. For all existing uses of expected_attach_type for this purpose, the result of this was only false negatives (i.e., freplace functions would be rejected by the verifier even though they were valid programs for the target they were replacing). However, should a false positive be introduced, this can lead to out-of-bounds accesses and/or crashes. The fix introduced in this patch is to propagate the expected_attach_type to the freplace program during verification, and reset it after that is done.

If an NMI or exception hits after a register is cleared, but before the UNWIND_HINT_REGS annotation, the ORC unwinder will wrongly think the previous value of the register was zero. This can confuse the unwinding process and cause it to exit early. Because ORC is simpler than DWARF, there are a limited number of unwind annotation states, so it's not possible to add an individual unwind hint after each push/clear combination. Instead, the register clearing instructions need to be consolidated and moved to after the UNWIND_HINT_REGS annotation.

[ unwind stack ] When the unwinder goes through the NMI and the IRQ on the stack, and then sees fsnotify(), it doesn't have access to the value of R10, because it only has the five IRET registers. So the unwind stops prematurely. However, because the interrupt_entry() code is careful not to clobber R10 before saving the full regs, the unwinder should be able to read R10 from the previously saved full pt_regs associated with the NMI. Handle this case properly. When encountering an IRET regs frame immediately after a full pt_regs frame, use the pt_regs as a backup which can be used to get the C register values. Also, note that a call frame resets the 'prev_regs' value, because a function is free to clobber the registers. For this fix to work, the IRET and full regs frames must be adjacent, with no FUNC frames in between. So replace the FUNC hint in interrupt_entry() with an IRET_REGS hint.

Because of the ->ip_summed value, udp_manip_pkt() tries to update the outer checksum with the new address and port, leading to an invalid checksum sent on the wire, as the original null checksum obviously didn't take the old address and port into account. So, we can't take ->ip_summed into account in udp_manip_pkt(), as it might not refer to the checksum we're acting on. Instead, we can base the decision to update the UDP checksum entirely on the value of hdr->check, because it's null if and only if checksum is disabled: * A fully computed checksum can't be 0, since a 0 checksum is represented by the CSUM_MANGLED_0 value instead. * A partial checksum can't be 0, since the pseudo-header always adds at least one non-zero value (the UDP protocol type 0x11) and adding more values to the sum can't make it wrap to 0 as the carry is then added to the wrapped number. * A disabled checksum uses the special value 0. The problem seems to be there from day one, although it was probably not visible before UDP tunnels were implemented.

Setting au_rslack == au_ralign is probably correct for kerberos_v1 privacy, but kerberos_v2 privacy adds additional GSS data after the clear text RPC message. au_ralign needs to be smaller than au_rslack in that fairly common case. When xdr_buf_trim() is restored to gss_unwrap_kerberos_v2(), it does exactly what I feared it would: it trims off part of the clear text RPC message. However, that's because rpc_prepare_reply_pages() does not set up the rq_rcv_buf's tail correctly because au_ralign is too large. Fixing the au_ralign computation also corrects the alignment of rq_rcv_buf->pages so that the client does not have to shift reply data payloads after they are received.

The computed checksum on the retransmitted request does not match the cached checksum, resulting in the server performing the retransmitted request again instead of returning the cached reply. The assumptions made when removing xdr_buf_trim() were not correct. In the send paths, the upper layer has already set the segment lengths correctly, and shorting the buffer's content is simply a matter of reducing buf->len. xdr_buf_trim() is the right answer in the receive/unwrap path on both the client and the server. The buffer segment lengths have to be shortened one-by-one. On the server side in particular, head.iov_len needs to be updated correctly to enable nfsd_cache_csum() to work correctly. The simple buf->len computation doesn't do that, and that results in checksumming stale data in the buffer. The problem isn't noticed until there's significant instability of the RPC transport. At that point, the reliability of retransmit detection on the server becomes crucial.

Consider the following example with comments explaining how and why it happens. $ mkfs.btrfs -f /dev/sdb $ mount /dev/sdb /mnt # Create our test file with 2 consecutive prealloc extents, each with a # size of 128Kb, and covering the range from 0 to 256Kb, with a file # size of 0. $ xfs_io -f -c "falloc -k 0 128K" /mnt/foo $ xfs_io -c "falloc -k 128K 128K" /mnt/foo # Fsync the file to record both extents in the log tree. $ xfs_io -c "fsync" /mnt/foo # Now do a redudant extent allocation for the range from 0 to 64Kb. # This will merely increase the file size from 0 to 64Kb. Instead we # could also do a truncate to set the file size to 64Kb. $ xfs_io -c "falloc 0 64K" /mnt/foo # Fsync the file, so we update the inode item in the log tree with the # new file size (64Kb). This also ends up setting the number of bytes # for the first prealloc extent to 64Kb. This is done by the truncation # at btrfs_log_prealloc_extents(). # This means that if a power failure happens after this, a write into # the file range 64Kb to 128Kb will not use the prealloc extent and # will result in allocation of a new extent. $ xfs_io -c "fsync" /mnt/foo # Now set the file size to 256K with a truncate and then fsync the file. # Since no changes happened to the extents, the fsync only updates the # i_size in the inode item at the log tree. This results in an implicit # hole for the file range from 64Kb to 128Kb, something which fsck will # complain when not using the NO_HOLES feature if we replay the log # after a power failure. $ xfs_io -c "truncate 256K" -c "fsync" /mnt/foo So instead of always truncating the log to the inode's current i_size at btrfs_log_prealloc_extents(), check first if there's a prealloc extent that starts at an offset lower than the i_size and with a length that crosses the i_size - if there is one, just make sure we truncate to a size that corresponds to the end offset of that prealloc extent, so that we don't lose the part of that extent that starts at i_size if a power failure happens.

[CAUSE] This is because we're calling btrfs_join_transaction() without re-using the current running one: btrfs_finish_ordered_io() |- btrfs_join_transaction() <<< Call #1 |- btrfs_record_root_in_trans() |- btrfs_reserve_extent() |- btrfs_join_transaction() <<< Call #2 Normally such btrfs_join_transaction() call should re-use the existing one, without trying to re-start a transaction. But the problem is, in btrfs_join_transaction() call #1, we call btrfs_record_root_in_trans() before initializing current::journal_info. And in btrfs_join_transaction() call #2, we're relying on current::journal_info to avoid such deadlock. [FIX] Call btrfs_record_root_in_trans() after we have initialized current::journal_info.

When channels are randomly plugged and unplugged out of order, the serial indexing breaks. Convert channel indexing to using IDA tracking in order to allow dynamic assignment. The previous code does not cause any regression bug for existing channel allocation besides idxd driver since the hotplug usage case is only used by idxd at this point. With this change, the chan->idr_ref is also not needed any longer. We can have a device with no channels registered due to hot plug. The channel device release code no longer should attempt to free the dma device id on the last channel release.

The history of this bug is interesting. I though that the commit 2d88ce76eb98 ("dmatest: add a 'wait' parameter") is a culprit, but looking closer to the code I think it simple revealed the broken logic from the day one, i.e. in the commit 0a2ff57d6fba ("dmaengine: dmatest: add a maximum number of test iterations") which adds iterations parameter. So, to the point, the conditional of checking the thread to be stopped being first part of conjunction logic prevents to check iterations. Thus, we have to always check both conditions to be able to stop after given iterations. Since it wasn't visible before second commit appeared, I add a respective Fixes tag.

This causes the same packet to be delivered multiple times to monitoring devices. We want to continue to deliver packets to monitoring devices before it is put in the virtqueue, to avoid that replies can appear in the packet capture before the transmitted packet. This patch fixes the issue, adding a new flag (tap_delivered) in struct virtio_vsock_pkt, to check if the packet is already delivered to monitoring devices.

Fix the logic that sets the enable/disable flag for the source MAC filter according to firmware spec 1.7.1. In the original firmware spec. before 1.7.1, the VF spoof check flags were not latched after making the HWRM_FUNC_CFG call, so there was a need to keep the func_flags so that subsequent calls would perserve the VF spoof check setting. A change was made in the 1.7.1 spec so that the flags became latched.

It's also questionable whether the GPIO specifier with GPIO_ACTIVE_HIGH is even correct, since the FUSB302 datasheet says INT_N is an "Active-LOW open-drain interrupt output", and the Pinebook Pro schematic shows it wired directly to the GPIO pin.

When tcp_bpf_recvmsg() returns, local variable "psock" becomes invalid, so the refcount should be decreased to keep refcount balanced. The reference counting issue happens in several exception handling paths of tcp_bpf_recvmsg(). When those error scenarios occur such as "flags" includes MSG_ERRQUEUE, the function forgets to decrease the refcnt increased by sk_psock_get(), causing a refcnt leak. Fix this issue by calling sk_psock_put() or pulling up the error queue read handling when those error scenarios occur.

The reference counting issue happens in one exception handling path of davinci_mcasp_get_dma_type().

When this is done, and crashdump is triggered, it will crash on null pointer dereference, since we make assumptions over what call_usermodehelper_exec() did. This has been reported by Sergey when one triggers a a coredump with the following configuration: ``` CONFIG_STATIC_USERMODEHELPER=y CONFIG_STATIC_USERMODEHELPER_PATH="" kernel.core_pattern = |/usr/lib/systemd/systemd-coredump %P %u %g %s %t %c %h %e ``` The way disabling the umh was designed was that call_usermodehelper_exec() would just return early, without an error. But coredump assumes certain variables are set up for us when this happens, and calls ile_start_write(cprm.file) with a NULL file.

However, if a consumer is waiting for mandatory suppliers to register, that could still block a consumer from probing. This commit fixes that by making sure in permissive mode, all suppliers to a consumer are treated as a optional suppliers. So, even if a consumer is waiting for suppliers to register and link itself (using the DL_FLAG_SYNC_STATE_ONLY flag) to the supplier, the consumer is never blocked from probing.

However, Yoshihiro Shimoda reported that on his device that expects to have unmet dependencies (due to "optional links" in its devicetree), was failing to mount the NFS root. In digging further, it seemed the problem was that while the device properly probes after waiting 30 seconds for any missing modules to load, the ip_auto_config() had already failed, resulting in NFS to fail. This was due to ip_auto_config() calling wait_for_device_probe() which doesn't wait for the driver_deferred_probe_timeout to fire. Fixing that issue is possible, but could also introduce 30 second delays in bootups for users who don't have any missing dependencies, which is not ideal. So I think the best solution to avoid any regressions is to revert back to a default timeout value of zero, and allow systems that need to utilize the timeout in order for userland to load any modules that supply misisng dependencies in the dts to specify the timeout length via the exiting documented boot argument.

This means folks are now seeing a big backtrace in their boot logs if there a entry in their dts that doesn't have a driver. To fix this, lets use dev_warn(), instead of dev_WARN() to match the previous error path. Cc: "David S. Miller" Cc: Alexey Kuznetsov Cc: Hideaki YOSHIFUJI Cc: Jakub Kicinski Cc: Rafael J.

However, Yoshihiro Shimoda reported that on his device that expects to have unmet dependencies (due to "optional links" in its devicetree), was failing to mount the NFS root. In digging further, it seemed the problem was that while the device properly probes after waiting 30 seconds for any missing modules to load, the ip_auto_config() had already failed, resulting in NFS to fail. This was due to ip_auto_config() calling wait_for_device_probe() which doesn't wait for the driver_deferred_probe_timeout to fire. This patch tries to fix the issue by creating a waitqueue for the driver_deferred_probe_timeout, and calling wait_event() to make sure driver_deferred_probe_timeout is zero in wait_for_device_probe() to make sure all the probing is finished. The downside to this solution is that kernel functionality that uses wait_for_device_probe(), will block until the driver_deferred_probe_timeout fires, regardless of if there is any missing dependencies. However, the previous patch reverts the default timeout value to zero, so this side-effect will only affect users who specify a driver_deferred_probe_timeout= value as a boot argument, where the additional delay would be beneficial to allow modules to load later during boot. Thanks to Geert for chasing down that ip_auto_config was why NFS was failing in this case! Cc: "David S. Miller" Cc: Alexey Kuznetsov Cc: Hideaki YOSHIFUJI Cc: Jakub Kicinski Cc: Rafael J.

The rpciod workqueue is on the write-out path for freeing dirty memory, so it is important that it never block waiting for memory to be allocated - this can lead to a deadlock. rpc_execute() - which is often called by an rpciod work item - calls rcp_task_release_client() which can lead to rpc_free_client(). rpc_free_client() makes two calls which could potentially block wating for memory allocation. rpc_clnt_debugfs_unregister() calls into debugfs and will block while any of the debugfs files are being accessed. In particular it can block while any of the 'open' methods are being called and all of these use malloc for one thing or another. So this can deadlock if the memory allocation waits for NFS to complete some writes via rpciod. rpc_clnt_remove_pipedir() can take the inode_lock() and while it isn't obvious that memory allocations can happen while the lock it held, it is safer to assume they might and to not let rpciod call rpc_clnt_remove_pipedir(). So this patch moves these two calls (together with the final kfree() and rpciod_down()) into a work-item to be run from the system work-queue. rpciod can continue its important work, and the final stages of the free can happen whenever they happen. I have seen this deadlock on a 4.12 based kernel where debugfs used synchronize_srcu() when removing objects. synchronize_srcu() requires a workqueue and there were no free workther threads and none could be allocated. While debugsfs no longer uses SRCU, I believe the deadlock is still possible.

[How] Apply the Raven workaround generically. When close enough to VUPDATE block cursor updates from occurring from the dc_stream_set_cursor_* helpers. This could perhaps be a little smarter by checking if there were pending updates or flips earlier in the frame on the HUBP side before applying the delay, but this should be fine for now. This fixes the kms_cursor_legacy test.

This results in a silent lockup in printk("%pg") called via warnf() from get_tree_bdev() under some circumstances when there's a race with the blockdev being frozen. This can be caused by xfstests/tests/generic/085 in combination with Lukas Czerner's ext4 mount API conversion patchset. It looks like it ought to occur with other users of get_tree_bdev() such as XFS, but apparently doesn't. Fix this by switching the order of the lines.

The problem is that __map_bio reads the flag before it potentially being modified by choose_pgpath, and ends up using the older value. The WARN_ON below is not trivially linked to the issue. It goes like this: The activate_path delayed_work is not initialized for non-scsi_dh devices, but we always set MPATHF_QUEUE_IO, asking for initialization. That is fine, since MPATHF_QUEUE_IO would be cleared in choose_pgpath. Nevertheless, only for BIO-based mpath, we cache the flag before calling choose_pgpath, and use the older version when deciding if we should initialize the path. Therefore, we end up trying to initialize the paths, and calling the non-initialized activate_path work.

In particular, usbhid_stop() does: usb_free_urb(usbhid->urbin); ... usbhid->urbin = NULL; /* don't mess up next start */ and usbhid_close() does: usb_kill_urb(usbhid->urbin); with no mutual exclusion. If the two routines happen to run concurrently so that usb_kill_urb() is called in between the usb_free_urb() and the NULL assignment, it will access the deallocated urb structure -- a use-after-free bug. This patch adds a mutex to the usbhid private structure and uses it to enforce mutual exclusion of the usbhid_start(), usbhid_stop(), usbhid_open() and usbhid_close() callbacks.

MPTCP however uses mptcp_stream_connect, not inet_stream_connect, for the mptcp-socket connect call. inet_stream_connect only gets called indirectly, for the tcp socket, so any ->disconnect() calls end up calling tcp_disconnect for that tcp subflow sk. This also explains why syzkaller has not yet reported a problem here. So for now replace this with a stub that doesn't do anything.

However, the spec has since been updated in RFC6040 to recommend slightly different decapsulation semantics. This was implemented in the kernel as a set of common helpers for ECN decapsulation, so let's just switch over WireGuard to using those, so it can benefit from this enhancement and any future tweaks. We do not drop packets with invalid ECN marking combinations, because WireGuard is frequently used to work around broken ISPs, which could be doing that.

Donenfeld" Date: Wed, 22 Apr 2020 17:18:53 -0600 Subject: crypto: arch/lib - limit simd usage to 4k chunks The initial Zinc patchset, after some mailing list discussion, contained code to ensure that kernel_fpu_enable would not be kept on for more than a 4k chunk, since it disables preemption. The choice of 4k isn't totally scientific, but it's not a bad guess either, and it's what's used in both the x86 poly1305, blake2s, and nhpoly1305 code already (in the form of PAGE_SIZE, which this commit corrects to be explicitly 4k for the former two). Ard did some back of the envelope calculations and found that at 5 cycles/byte (overestimate) on a 1ghz processor (pretty slow), 4k means we have a maximum preemption disabling of 20us, which Sebastian confirmed was probably a good limit. Unfortunately the chunking appears to have been left out of the final patchset that added the glue code. So, this commit adds it back in.

O_TRUNC is one of these. Normally this is not a problem as VFS calls ->setattr() with zero size and underlying filesystem sets file size to 0. But when overlayfs is running on top of virtiofs, it has an optimization where it does not send setattr request to server if dectects that truncation is part of open(O_TRUNC). It assumes that server already zeroed file size as part of open(O_TRUNC). fuse_do_setattr() { if (attr->ia_valid & ATTR_OPEN) { /* * No need to send request to userspace, since actual * truncation has already been done by OPEN. But still * need to truncate page cache. */ } } IOW, fuse expects O_TRUNC to be passed to it as part of open flags. But currently overlayfs does not pass O_TRUNC to underlying filesystem hence fuse/virtiofs breaks. Setup overlayfs on top of virtiofs and following does not zero the file size of a file is either upper only or has already been copied up. fd = open(foo.txt, O_TRUNC | O_WRONLY); There are two ways to fix this. Either pass O_TRUNC to underlying filesystem or clear ATTR_OPEN from attr->ia_valid so that fuse ends up sending a SETATTR request to server. Miklos is concerned that O_TRUNC might have side affects so it is better to clear ATTR_OPEN for now. Hence this patch clears ATTR_OPEN from attr->ia_valid. I found this problem while running unionmount-testsuite. With this patch, unionmount-testsuite passes with overlayfs on top of virtiofs.

Ensure these arguments are evaluated before user access is allowed. This improves security by reducing code with access to userspace, but it also fixes a PREEMPT bug with KUAP on powerpc/64s: stable_page_flags() is currently called with AMR set to allow writes, it ends up calling spin_unlock(), which can call preempt_schedule. But the task switch code can not be called with AMR set (it relies on interrupts saving the register), so this blows up. It's fine if the code inside allow_user_access() is preemptible, because a timer or IPI will save the AMR, but it's not okay to explicitly cause a reschedule.

My solution now ensures that the two drivers can only be enabled when the dependencies are met: - When the platform specific drivers are built-in, everything is fine, as SOC_SOF_OF is either =y or =m - When both are loadable modules, it also works, both for Kconfig and at runtime - When the hardware drivers are loadable modules or disabled, and SOC_SOF_OF=y, prevent the IMX_SOF_OF drivers from being turned on, as this would be broken. It seems that this is just an elaborate way to describe two tristate symbols that have straight dependencies, but maybe I'm missing some subtle point. It seems to always build for me now.

It's better to pr_warn() all user of ioctl_fibmap() and return a proper error code rather than silently letting a FS corruption happen if the user tries to fiddle around with the returned block map address. We fix this by returning an error code of -ERANGE and returning 0 as the block mapping address in case if it is > INT_MAX. Now iomap_bmap() could be called from either of these two paths. Either when a user is calling an ioctl_fibmap() interface to get the block mapping address or by some filesystem via use of bmap() internal kernel API. bmap() kernel API is well equipped with handling of u64 addresses. WARN condition in iomap_bmap_actor() was mainly added to warn all the fibmap users. But now that we have directly added this warning for all fibmap users and also made sure to return 0 as block map address in case if addr > INT_MAX. So we can now remove this logic from iomap_bmap_actor(). Signed-off-by: Ritesh Harjani Reviewed-by: Christoph Hellwig Reviewed-by: Jan Kara Reviewed-by: Darrick J. Wong Signed-off-by: Darrick J.

However on bare metal targets (aarch64-none-elf), and on old gcc, async and sync unwind tables are not enabled by default to avoid runtime memory costs. This means if linux is built with a baremetal toolchain the vdso.so may not have unwind tables which breaks the gcc platform ABI guarantee in userspace. Add -fasynchronous-unwind-tables explicitly to the vgettimeofday.o cflags to address the ABI change.

However, this range does not include any direct map aliases changed in cpa_process_alias(). So small set_memory_() calls that touch that alias don't get the direct map changes flushed. This situation can happen when the virtual address taking variants are passed an address in vmalloc or modules space. In these cases, force a full TLB flush. Note this issue does not extend to cases where the set_memory_() calls are passed a direct map address, or page array, etc, as the primary target. In those cases the direct map would be flushed.

Client-driven CRQ initialization fails due to partner’s CRQ closed, causing client to enqueue a reset task for FATAL_ERROR. Then passive (server-driven) CRQ initialization succeeds, causing client to release CRQ and enqueue a reset task for failover. If the passive CRQ initialization occurs before the FATAL reset task is processed, the FATAL error reset task would try to access a CRQ message queue that was freed, causing an oops. The problem may be most likely to occur during DLPAR add vNIC with a non-default MTU, because the DLPAR process will automatically issue a change MTU request.

Since the FPU may not be usable in the softirq context, the call to decrypt may be scheduled on the cryptd work queue. The cryptd work queue does not provide ordering guarantees. Therefore, preserving order requires masking out ASYNC implementations of gcm(aes). For instance, an Intel CPU with AES-NI makes available the generic-gcm-aesni driver from the aesni_intel module to implement gcm(aes). However, this implementation requires the FPU, so it is not always available to use from a softirq context, and will fallback to the cryptd work queue, which does not preserve frame ordering. With this change, such a system would select gcm_base(ctr(aes-aesni),ghash-generic). While the aes-aesni implementation prefers to use the FPU, it will fallback to the aes-asm implementation if unavailable. By using a synchronous version of gcm(aes), the decryption will complete before returning from crypto_aead_decrypt(). Therefore, the macsec_decrypt_done() callback will be called before returning from macsec_decrypt(). Thus, the order of calls to macsec_post_decrypt() for the frames is preserved. While it's presumable that the pure AES-NI version of gcm(aes) is more performant, the hybrid solution is capable of gigabit speeds on modest hardware. Regardless, preserving the order of frames is paramount for many network protocols (e.g., triggering TCP retries). Within the MACsec driver itself, the replay protection is tripped by the out-of-order frames, and can cause frames to be dropped. This bug has been present in this code since it was added in v4.6, however it may not have been noticed since not all CPUs have FPU offload available. Additionally, the bug manifests as occasional out-of-order packets that are easily misattributed to other network phenomena. When this code was added in v4.6, the crypto/gcm.c code did not restrict selection of the ghash function based on the ASYNC flag. For instance, x86 CPUs with PCLMULQDQ would select the ghash-clmulni driver instead of ghash-generic, which submits to the cryptd work queue if the FPU is busy. However, this bug was was corrected in v4.8 by commit b30bdfa86431afbafe15284a3ad5ac19b49b88e3, and was backported all the way back to the v3.14 stable branch, so this patch should be applicable back to the v4.6 stable branch.

This stops all further parsing of the parmeter by VFS. Furthermore, if an LSM hook returns a success, the remaining LSM hooks are not invoked for the parameter. The current default behavior of returning success means that all the parameters are expected to be parsed by the LSM hook and none of them end up being populated by vfs in fs_context This was noticed when lsm=bpf is supplied on the command line before any other LSM. As the bpf lsm uses this default value to implement a default hook, this resulted in a failure to parse any fs_context parameters and a failure to mount the root filesystem.

This isn't great, as userspace can then observe this value and get a bit confused. Conversly, userspace can do things like (in the context of a 64bit guest that is capable of 32bit EL0) setting PSTATE to AArch64-EL0, set PC to a 64bit value, change PSTATE to AArch32-USR, and observe that PC hasn't been truncated. More confusion. Fix both by: - truncating PC increments for 32bit guests - sanitizing all 32bit regs every time a core reg is changed by userspace, and that PSTATE indicates a 32bit mode.

UNAME_M = $(shell uname -m) variable is used to define the target programs and libraries to be built from arch specific sources in sub-directories. For cross-builds to work, UNAME_M has to map to ARCH and arch specific directories and targets in this Makefile. UNAME_M variable to used to run the compiles pointing to the right arch directories and build the right targets for these supported architectures. TEST_GEN_PROGS and LIBKVM are set using UNAME_M variable. LINUX_TOOL_ARCH_INCLUDE is set using ARCH variable. x86_64 targets are named to include x86_64 as a suffix and directories for includes are in x86_64 sub-directory. s390x and aarch64 follow the same convention. "uname -m" doesn't result in the correct mapping for s390x and aarch64. Fix it to set UNAME_M correctly for s390x and aarch64 cross-builds. In addition, Makefile doesn't create arch sub-directories in the case of relocatable builds and test programs under s390x and x86_64 directories fail to build. This is a problem for native and cross-builds. Fix it to create all necessary directories keying off of TEST_GEN_PROGS.

The initial printk cannot trigger this because that happens during boot when the local APIC timer is set up on the boot CPU. Prevent it by moving the printk to a place which is guaranteed to be only called once during boot. Mark the deadline timer check related functions and data __init while at it.

IPv4 has a per-network namespace generation id (rt_genid) that is bumped on changes to the FIB. Checking if a dst_entry is still valid means comparing rt_genid in the rtable to the current value of rt_genid for the namespace. IPv6 also has a per network namespace counter, fib6_sernum, but the count is saved per fib6_node. With the per-node counter only dst_entries based on fib entries under the node are invalidated when changes are made to the routes - limiting the scope of invalidations. IPv6 uses a reference in the rt6_info, 'from', to track the corresponding fib entry used to create the dst_entry. When validating a dst_entry, the 'from' is used to backtrack to the fib6_node and check the sernum of it to the cookie passed to the dst_check operation. With the inline format (nexthop definition inline with the fib6_info), dst_entries cached in the fib6_nh have a 1:1 correlation between fib entries, nexthop data and dst_entries. With external nexthops, IPv6 looks more like IPv4 which means multiple fib entries across disparate fib6_nodes can all reference the same fib6_nh. That means validation of dst_entries based on external nexthops needs to use the IPv4 format - the per-network namespace counter. Add sernum to rt6_info and set it when creating a pcpu dst entry. Update rt6_get_cookie to return sernum if it is set and update dst_check for IPv6 to look for sernum set and based the check on it if so. Finally, rt6_get_pcpu_route needs to validate the cached entry before returning a pcpu entry (similar to the rt_cache_valid calls in __mkroute_input and __mkroute_output for IPv4).

As a result it is possible to build PTP-capable Ethernet drivers without the PTP subsystem by deselecting PTP_1588_CLOCK. Drivers are required to handle the missing dependency gracefully. Some PTP-capable Ethernet drivers (e.g., TI_CPSW) factor their PTP code out into separate drivers (e.g., TI_CPTS_MOD). The above commit also changed these PTP-specific drivers to `imply PTP_1588_CLOCK`, making it possible to build them without the PTP subsystem. But as Grygorii Strashko noted in [1]: On Wed, Apr 22, 2020 at 02:16:11PM +0300, Grygorii Strashko wrote: > Another question is that CPTS completely nonfunctional in this case and > it was never expected that somebody will even try to use/run such > configuration (except for random build purposes). In my view, enabling a PTP-specific driver without the PTP subsystem is a configuration error made possible by the above commit. Kconfig should not allow users to create a configuration with missing dependencies that results in "completely nonfunctional" drivers. I audited all network drivers that call ptp_clock_register() but merely `imply PTP_1588_CLOCK` and found five PTP-specific drivers that are likely nonfunctional without PTP_1588_CLOCK: NET_DSA_MV88E6XXX_PTP NET_DSA_SJA1105_PTP MACB_USE_HWSTAMP CAVIUM_PTP TI_CPTS_MOD Note how these symbols all reference PTP or timestamping in their name; this is a clue that they depend on PTP_1588_CLOCK. Change them from `imply PTP_1588_CLOCK` [2] to `depends on PTP_1588_CLOCK`. I'm not using `select PTP_1588_CLOCK` here because PTP_1588_CLOCK has its own dependencies, which `select` would not transitively apply. Additionally, remove the `select NET_PTP_CLASSIFY` from CPTS_TI_MOD; PTP_1588_CLOCK already selects that.

The unconditional timeout was caused by VSOCK_DEFAULT_CONNECT_TIMEOUT of connecting from the client side. The vhost vsock client tries to connect an initializing virtio vsock server. The abnormal flow looks like: host-userspace vhost vsock guest vsock ============== =========== ============ connect() --------> vhost_transport_send_pkt_work() initializing | vq->private_data==NULL | will not be queued V schedule_timeout(2s) vhost_vsock_start() <--------- device ready set vq->private_data wait for 2s and failed connect() again vq->private_data!=NULL recv connecting pkt Details: 1. Host userspace sends a connect pkt, at that time, guest vsock is under initializing, hence the vhost_vsock_start has not been called. So vq->private_data==NULL, and the pkt is not been queued to send to guest 2. Then it sleeps for 2s 3. After guest vsock finishes initializing, vq->private_data is set 4. When host userspace wakes up after 2s, send connecting pkt again, everything is fine. As suggested by Stefano Garzarella, this fixes it by additional kicking the send_pkt worker in vhost_vsock_start once the virtio device is started. This makes the pending pkt sent again. After this patch, kata-runtime (with vsock enabled) boot time is reduced from 3s to 1s on a ThunderX2 arm64 server.

The crash is in interrupt_return() where we check lazy_irq_pending(), which calls get_paca() and with CONFIG_DEBUG_PREEMPT=y that goes to check_preemption_disabled() via debug_smp_processor_id(). As Nick explained on the list: Problem is MSR[RI] is cleared here, ready to do the last few things for interrupt return where we're not allowed to take any other interrupts. SLB interrupts can happen just about anywhere aside from kernel text, global variables, and stack. When that hits, it appears to be unrecoverable due to RI=0. The problematic access is in preempt_count() which is: return READ_ONCE(current_thread_info()->preempt_count); Because of THREAD_INFO_IN_TASK, current_thread_info() just points to current, so the access is to somewhere in kernel memory, but not on the stack or in .data, which means it can cause an SLB miss. If we take an SLB miss with RI=0 it is fatal. The easiest solution is to add a version of lazy_irq_pending() that doesn't do the preemption check and call it from the interrupt return path.

This is the really low-hanging fruit of removing a couple of zero-sized arrays in some core code.

The re-entrancy happens because the irq state is the OR of the interrupt state and the resamplefd state. That is, we don't want to show the state as 0 until we've had a chance to set the resamplefd. But if the interrupt has _not_ gone low then ioapic_set_irq is invoked again, causing an infinite loop. This can only happen for a level-triggered interrupt, otherwise irqfd_inject would immediately set the KVM_USERSPACE_IRQ_SOURCE_ID high and then low. Fortunately, in the case of level-triggered interrupts the VMEXIT already happens because TMR is set. Thus, fix the bug by restricting the lazy invocation of the ack notifier to edge-triggered interrupts, the only ones that need it.

However, there is one omission in the connection handling that when the connection or application is orderly shutdown (e.g. via SIGQUIT, etc.), the connection is not closed in kernel, the 'tipc_subscription' objects are not freed too. This results in: - The maximum number of subscriptions (65535) will be reached soon, new subscriptions will be rejected; - TIPC module cannot be removed (unless the objects are somehow forced to release first); The commit fixes the issue by closing the connection if the 'recvmsg()' returns '0' i.e. when the peer is shutdown gracefully.

Namely, during the reset we call usb_ep0_reinit() because the characteristics of ep0 may have changed (if the reset follows a firmware update, for example). While usb_ep0_reinit() is running there is a brief period during which the pointers stored in udev->ep_in[0] and udev->ep_out[0] are set to NULL, and if an URB is submitted to ep0 during that period, usb_urb_ep_type_check() will report it as a driver bug. In the absence of those pointers, the routine thinks that the endpoint doesn't exist. The log message looks like this: ------------[ cut here ]------------ usb 2-1: BOGUS urb xfer, pipe 2 != type 2 WARNING: CPU: 0 PID: 9241 at drivers/usb/core/urb.c:478 usb_submit_urb+0x1188/0x1460 drivers/usb/core/urb.c:478 Now, although submitting an URB while the device is being reset is a questionable thing to do, it shouldn't count as a driver bug as severe as submitting an URB for an endpoint that doesn't exist. Indeed, endpoint 0 always exists, even while the device is in its unconfigured state. To prevent these misleading driver bug reports, this patch updates usb_disable_endpoint() to avoid clearing the ep_in[] and ep_out[] pointers when the endpoint being disabled is ep0. There's no danger of leaving a stale pointer in place, because the usb_host_endpoint structure being pointed to is stored permanently in udev->ep0; it doesn't get deallocated until the entire usb_device structure does.

If these pages are then remapped into userspace as cacheable, they may not be coherent with the non-cacheable mappings. In particular this happens with libusb, when it attempts to create zero-copy buffers for use by rtl-sdr (https://github.com/osmocom/rtl-sdr/). On low end arm devices with non-coherent USB ports, the application will be unexpectedly killed, while continuing to work fine on arm machines with coherent USB controllers. This bug has been discovered/reported a few times over the last few years. In the case of rtl-sdr a compile time option to enable/disable zero copy was implemented to work around it. Rather than relaying on application specific workarounds, dma_mmap_coherent() can be used instead of remap_pfn_range(). The page cache/etc attributes will then be correctly set in userspace to match the kernel mapping.

However, at the moment the lpass-cpu driver has SD0 hard-coded for mono/stereo (or additional fixed SD lines for more channels). For weird reasons there seems to be hardware that uses one of the other SD lines for mono/stereo. For example, some Samsung devices use an external Speaker amplifier connected to Quaternary MI2S. For some reason, the SD line for audio playback was connected to SD1 rather than SD0. (I have no idea why...) At the moment, the lpass-cpu driver cannot be configured to work for the Speaker on these devices. The q6afe driver already allows configuring the MI2S SD lines through the "qcom,sd-lines" device tree property, but this works only when routing audio through the ADSP. This commit adds a very similar configuration for the lpass-cpu driver. It is now possible to add additional subnodes to the lpass device in the device tree, to configure the SD lines for playback and/or capture. E.g. for the Samsung devices mentioned above: &lpass { dai@3 { reg = ; qcom,playback-sd-lines = <1>; }; }; qcom,playback/capture-sd-lines takes a list of SD lines (0-3) in the same format as the q6afe driver. (The difference here is that q6afe has separate DAIs for playback/capture, while lpass-cpu has one for both...) For backwards compatibility with older device trees, the lpass-cpu driver defaults to LPAIF_I2SCTL_MODE_8CH if the subnode for a DAI is missing. This is equivalent to the previous behavior: Up to 8 channels can be configured, and SD0/QUAT01 will be chosen when setting up a stream with fewer channels. This allows the speaker to work on Samsung MSM8916 devices that use an external speaker amplifier.

They have detachable keyboards, so the hotkeys are send through a HID device (and handled by the hid-asus driver) and also the rfkill functionality is not used on these devices. Besides not adding any extra functionality, initializing the WMI interface on these devices actually has a negative side-effect. For some reason the \_SB.ATKD.INIT() function which asus_wmi_platform_init() calls drives GPO2 (INT33FC:02) pin 8, which is connected to the front facing webcam LED, high and there is no (WMI or other) interface to drive this low again causing the LED to be permanently on, even during suspend. This commit adds a blacklist of DMI system_ids on which not to load the asus-nb-wmi and adds these Transformer books to this list. This fixes the webcam LED being permanently on under Linux.

All in all, this is pretty pointless, and racy. There are no good reasons for this, and only drawbacks. Its pointless because chances are, the controller is going to do the same thing to determine if the link is down - attempt a PCI access and compare the result. This does not make the link status decision any smarter. Its racy because its possible that the link was down at the time of the MHI core access, but then recovered before the controller access. In this case, the controller will indicate the link is not down, and the MHI core will precede to use a bad value as the MHI core does not attempt to retry the access. Retrying the access in the MHI core is a bad idea because again, it is racy - what if the link is down again? Furthermore, there may be some higher level state associated with the link status, that is now invalid because the link went down. The only reason why the MHI core could see "invalid" data when doing a PCI access, that is actually valid, is if the register actually contained the PCI spec defined sentinel for an invalid access. In this case, it is arguable that the MHI implementation broken, and should be fixed, not worked around. Therefore, remove the link_status() callback before anyone attempts to implement it.

This assumption may not hold for all MHI devices. The controller knows what is the physical link (ie PCI, I2C, SPI, etc), and therefore knows the proper methods to access that link. The controller can also handle link specific error scenarios, such as reading -1 when the PCI link went down. Therefore, it is appropriate that the MHI core requests the controller to make register accesses on behalf of the core, which abstracts the core from link specifics, and end up removing an unnecessary assumption.

This is because the device names assigned to the MHI channel devices are non-unique. They consist of the channel's name, and the channel's pipe id. For identical products, each instance is going to have the same set of channel (both in name and pipe id). To fix this, we prepend the device name of the parent device that the MHI channels belong to. Since different instances of the same product should have unique device names, this makes the MHI channel devices for each product also unique. Additionally, remove the pipe id from the MHI channel device name. This is an internal detail to the MHI product that provides little value, and imposes too much device specific internal details to userspace. It is expected that channel with a specific name (ie "SAHARA") has a specific client, and it does not matter what pipe id that channel is enumerated on. The pipe id is an internal detail between the MHI bus, and the hardware. The client is not expected to make decisions based on the pipe id, and to do so would require the client to have intimate knowledge of the hardware, which is inappropiate as it may violate the layering provided by the MHI bus. The limitation of doing this is that each product may only have one instance of a channel by a unique name. This limitation is appropriate given the usecases of MHI channels.

Once a cgroup goes over budget from forced IOs, it has to pay it back with its future budget. The progress guarantee on debt paying comes from the iocg being active - active iocgs are processed by the periodic timer, which ensures that as time passes the debts dissipate and the iocg returns to normal operation. However, both iocg activation and vdebt handling are asynchronous and a sequence like the following may happen. 1. The iocg is in the process of being deactivated by the periodic timer. 2. A bio enters ioc_rqos_throttle(), calls iocg_activate() which returns without anything because it still sees that the iocg is already active. 3. The iocg is deactivated. 4. The bio from #2 is over budget but needs to be forced. It increases abs_vdebt and goes over the threshold and enables use_delay. 5. IO control is enabled for the iocg's subtree and now IOs are attributed to the descendant cgroups and the iocg itself no longer issues IOs. This leaves the iocg with stuck abs_vdebt - it has debt but inactive and no further IOs which can activate it. This can end up unduly punishing all the descendants cgroups. The usual throttling path has the same issue - the iocg must be active while throttled to ensure that future event will wake it up - and solves the problem by synchronizing the throttling path with a spinlock. abs_vdebt handling is another form of overage handling and shares a lot of characteristics including the fact that it isn't in the hottest path. This patch fixes the above and other possible races by strictly synchronizing abs_vdebt and use_delay handling with iocg->waitq.lock.

This is probably because the modem first uses gpio_149 to signal the SoC that data will be sent, and the CTS will only get used later when the data transfer is starting. Let's fix the issue by configuring the gpio_149 pad as the wakeirq for UART. We have gpio_149 managed by the USB PHY for powering up the right USB mode, and after that, the gpio gets recycled as the modem wake-up pin. If needeed, the USB PHY can also later on be configured to use gpio_149 pad as the wakeirq as a shared irq. Let's also configure the missing properties for uart-has-rtscts and current-speed for the modem port while at it. We already configure the hardware flow control pins with uart1_pins pinctrl setting.

But this is not correct because apply_bytes is itself modified in the main loop doing the mem_charge. Then at the end of this we have sg.size incorrectly set and out of sync with actual sk values. Then we can get a splat if we try to cork the data later and again try to redirect the msg to ingress. To fix instead of trying to track msg.size do the easy thing and include it as part of the sk_msg_xfer logic so that when the msg is moved the sg.size is always correct.

Instead of renting multiple VMs from a Cloud + Provider, using nested KVM lets you rent a large enough "guest + hypervisor" (level-1 guest). This in turn allows you to create + multiple nested guests (level-2 guests), running different OSes, on + which you can develop and test your software. + +- Live migration of "guest hypervisors" and their nested guests, for + load balancing, disaster recovery, etc. + +- VM image creation tools (e.g. ``virt-install``, etc) often run + their own VM, and users expect these to work inside a VM. + +- Some OSes use virtualization internally for security (e.g. to let + applications run safely in isolation). + + +Enabling "nested" (x86) +----------------------- + +From Linux kernel v4.19 onwards, the ``nested`` KVM parameter is enabled +by default for Intel and AMD. (Though your Linux distribution might +override this default.) + +In case you are running a Linux kernel older than v4.19, to enable +nesting, set the ``nested`` KVM module parameter to ``Y`` or ``1``. To +persist this setting across reboots, you can add it in a config file, as +shown below: + +1. On the bare metal host (L0), list the kernel modules and ensure that + the KVM modules:: + + $ lsmod | grep -i kvm + kvm_intel 133627 0 + kvm 435079 1 kvm_intel + +2. Show information for ``kvm_intel`` module:: + + $ modinfo kvm_intel | grep -i nested + parm: nested:bool + +3. For the nested KVM configuration to persist across reboots, place the + below in ``/etc/modprobed/kvm_intel.conf`` (create the file if it + doesn't exist):: + + $ cat /etc/modprobe.d/kvm_intel.conf + options kvm-intel nested=y + +4. Unload and re-load the KVM Intel module:: + + $ sudo rmmod kvm-intel + $ sudo modprobe kvm-intel + +5. Verify if the ``nested`` parameter for KVM is enabled:: + + $ cat /sys/module/kvm_intel/parameters/nested + Y + +For AMD hosts, the process is the same as above, except that the module +name is ``kvm-amd``. + + +Additional nested-related kernel parameters (x86) +------------------------------------------------- + +If your hardware is sufficiently advanced (Intel Haswell processor or +higher, which has newer hardware virt extensions), the following +additional features will also be enabled by default: "Shadow VMCS +(Virtual Machine Control Structure)", APIC Virtualization on your bare +metal host (L0). Parameters for Intel hosts:: + + $ cat /sys/module/kvm_intel/parameters/enable_shadow_vmcs + Y + + $ cat /sys/module/kvm_intel/parameters/enable_apicv + Y + + $ cat /sys/module/kvm_intel/parameters/ept + Y + +.. note:: If you suspect your L2 (i.e. nested guest) is running slower, + ensure the above are enabled (particularly + ``enable_shadow_vmcs`` and ``ept``). + + +Starting a nested guest (x86) +----------------------------- + +Once your bare metal host (L0) is configured for nesting, you should be +able to start an L1 guest with:: + + $ qemu-kvm -cpu host [...] + +The above will pass through the host CPU's capabilities as-is to the +gues); or for better live migration compatibility, use a named CPU +model supported by QEMU. e.g.:: + + $ qemu-kvm -cpu Haswell-noTSX-IBRS,vmx=on + +then the guest hypervisor will subsequently be capable of running a +nested guest with accelerated KVM. + + +Enabling "nested" (s390x) +------------------------- + +1. On the host hypervisor (L0), enable the ``nested`` parameter on + s390x:: + + $ rmmod kvm + $ modprobe kvm nested=1 + +.. note:: On s390x, the kernel parameter ``hpage`` is mutually exclusive + with the ``nested`` paramter — i.e. to be able to enable + ``nested``, the ``hpage`` parameter *must* be disabled. + +2. The guest hypervisor (L1) must be provided with the ``sie`` CPU + feature — with QEMU, this can be done by using "host passthrough" + (via the command-line ``-cpu host``). + +3. Now the KVM module can be loaded in the L1 (guest hypervisor):: + + $ modprobe kvm + + +Live migration with nested KVM +------------------------------ + +Migrating an L1 guest, with a *live* nested guest in it, to another +bare metal host, works as of Linux kernel 5.3 and QEMU 4.2.0 for +Intel x86 systems, and even on older versions for s390x. + +On AMD systems, once an L1 guest has started an L2 guest, the L1 guest +should no longer be migrated or saved (refer to QEMU documentation on +"savevm"/"loadvm") until the L2 guest shuts down. Attempting to migrate +or save-and-load an L1 guest while an L2 guest is running will result in +undefined behavior. You might see a ``kernel BUG!`` entry in ``dmesg``, a +kernel 'oops', or an outright kernel panic. Such a migrated or loaded L1 +guest can no longer be considered stable or secure, and must be restarted. +Migrating an L1 guest merely configured to support nesting, while not +actually running L2 guests, is expected to function normally even on AMD +systems but may fail once guests are started. + +Migrating an L2 guest is always expected to succeed, so all the following +scenarios should work even on AMD systems: + +- Migrating a nested guest (L2) to another L1 guest on the *same* bare + metal host. + +- Migrating a nested guest (L2) to another L1 guest on a *different* + bare metal host. + +- Migrating a nested guest (L2) to a bare metal host. + +Reporting bugs from nested setups +----------------------------------- + +Debugging "nested" problems can involve sifting through log files across +L0, L1 and L2; this can result in tedious back-n-forth between the bug +reporter and the bug fixer. + +- Mention that you are in a "nested" setup. If you are running any kind + of "nesting" at all, say so. Unfortunately, this needs to be called + out because when reporting bugs, people tend to forget to even + *mention* that they're using nested virtualization. + +- Ensure you are actually running KVM on KVM. Sometimes people do not + have KVM enabled for their guest hypervisor (L1), which results in + them running with pure emulation or what QEMU calls it as "TCG", but + they think they're running nested KVM.

Issue Can be reproduced by: arecord -D hw:2,0 -f dat -d 60 /tmp/test0 & arecord -D hw:2,2 -f dat -d 60 /tmp/test1 & cat /proc/asound/card2/pcm?c/sub0/status Actual issue is : When we open one capture stream on one instance lets say I2S_SP and then once again if we open other capture on other instance lets say I2S_BT while first capture is in progress and when we try to read the status of both running instances by below command cat /proc/asound/card2/pcm?c/sub0/status we observe that avail_max is being doubled on first opened capture(I2S_SP in the example). This is because our previous implementation was like when any instance is opened it gets initialized in dma_open irrespective of on what instance it called open. For example: First I2S_SP called opened it initializes both SP/BT capture streams irrespective of on which instance the stream opened.next time I2S_BT called opened and it initializes both SP/BT this corrupts the behaviour . So with this patch the stream gets initialized only on specific instance when ever it gets opened calls hw_params. This rectifies the issue.

This turns out to be a problem because function signal_our_withdraw() repeatedly calls check_journal_clean() which reads the metadata (both its dinode and indirect blocks) to see if the entire journal is mapped. The dinode read works, but reading the indirect blocks returns -EIO which gets sent back up and causes a consistency error. This results in withdraw-from-withdraw, which becomes a deadlock. This patch changes the test in gfs2_meta_read() to allow all metadata reads for the journal. Instead of checking the journal block, it now checks for the journal inode glock which is the same for all blocks in the journal. This allows check_journal_clean() to properly check the journal without trying to withdraw recursively.

When fed a signal with 50% duty cycle, it will timestamp both the rising and the falling edge. When fed a short pulse signal, only the timestamp of the falling edge will be seen in the PTPSYNCTS register, because that of the rising edge had been overwritten. So the moral is: don't feed it short pulse inputs. Luckily this is not a complete deal breaker, as we can still work with 1 Hz square waves. But the problem is that the extts polling period was not dimensioned enough for this input signal. If we leave the period at half a second, we risk losing timestamps due to jitter in the measuring process. So we need to increase it to 4 times per second. Also, the very least we can do to inform the user is to deny any other flags combination than with PTP_RISING_EDGE and PTP_FALLING_EDGE both set.

We can unmask that interrupt and so respond to a semaphore wait by yielding the timeslice, if we have another context to yield to! The only real complication is that the interrupt is only generated for the start of the semaphore wait, and is asynchronous to our process_csb() -- that is, we may not have registered the timeslice before we see the interrupt. To ensure we don't miss a potential semaphore blocking forward progress (e.g. selftests/live_timeslice_preempt) we mark the interrupt and apply it to the next timeslice regardless of whether it was active at the time. v2: We use semaphores in preempt-to-busy, within the timeslicing implementation itself! Ergo, when we do insert a preemption due to an expired timeslice, the new context may start with the missed semaphore flagged by the retired context and be yielded, ad infinitum. To avoid this, read the context id at the time of the semaphore interrupt and only yield if that context is still active.

Once upon a time, it said that it uses the upper 32b to decide if it should perform a lite-restore, and so we must ensure that each unique context submitted to HW is given a unique CCID [for the duration of it being on the HW]. Currently, this is achieved by using a small circular tag, and assigning every context submitted to HW a new id. However, this tag is being cleared on repinning an inflight context such that we end up re-using the 0 tag for multiple contexts. To avoid accidentally clearing the CCID in the upper 32bits of the LRC descriptor, split the descriptor into two dwords so we can update the GGTT address separately from the CCID.

However, if we continually preempt an active context such that it always remains inflight, it can be resubmitted with an arbitrary number of paired contexts. As each of its paired contexts will use a new CCID, eventually it will wrap and submit two ELSP with the same CCID. Rather than use a simple circular counter, switch over to a small bitmap of inflight ids so we can avoid reusing one that is still potentially active.

While that change should not make any difference it confuses GCC which fails to work out that oldval is not referenced when the return value is not zero. GCC fails to properly analyze arch_futex_atomic_op_inuser(). It's not the early return, the issue is with the assembly macros. GCC fails to detect that those either set 'ret' to 0 and set oldval or set 'ret' to -EFAULT which makes oldval uninteresting. The store to the callsite supplied oldval pointer is conditional on ret == 0. The straight forward way to solve this is to make the store unconditional. Aside of addressing the build warning this makes sense anyway because it removes the conditional from the fastpath. In the error case the stored value is uninteresting and the extra store does not matter at all.

RFC8754 (section 4.1) defines the SR source node behavior which encapsulates packets into an outer IPv6 header and SRH. The SR source node encodes the full list of Segments that defines the packet path in the SRH. Then, the first segment from list of Segments is copied into the Destination address of the outer IPv6 header and the packet is sent to the first hop in its path towards the destination. If the Segment list has only one segment, the SR source node can omit the SRH as he only segment is added in the destination address. RFC8754 (section 4.1.1) defines the Reduced SRH, when a source does not require the entire SID list to be preserved in the SRH. A reduced SRH does not contain the first segment of the related SR Policy (the first segment is the one already in the DA of the IPv6 header), and the Last Entry field is set to n-2, where n is the number of elements in the SR Policy. RFC8754 (section 4.3.1.1) defines the SRH processing and the logic to validate the SRH (S09, S10, S11) which works for both reduced and non-reduced behaviors. This patch updates seg6_validate_srh() to validate the SRH as per RFC8754. Signed-off-by: Ahmed Abdelsalam Signed-off-by: David S.

Donenfeld" Date: Wed, 6 May 2020 15:33:03 -0600 Subject: wireguard: socket: remove errant restriction on looping to self It's already possible to create two different interfaces and loop packets between them. This has always been possible with tunnels in the kernel, and isn't specific to wireguard. Therefore, the networking stack already needs to deal with that. At the very least, the packet winds up exceeding the MTU and is discarded at that point. So, since this is already something that happens, there's no need to forbid the not very exceptional case of routing a packet back to the same interface; this loop is no different than others, and we shouldn't special case it, but rather rely on generic handling of loops in general. This also makes it easier to do interesting things with wireguard such as onion routing. At the same time, we add a selftest for this, ensuring that both onion routing works and infinite routing loops do not crash the kernel. We also add a test case for wireguard interfaces nesting packets and sending traffic between each other, as well as the loop in this case too. We make sure to send some throughput-heavy traffic for this use case, to stress out any possible recursion issues with the locks around workqueues.

That turned out not to be okay on systems without forced preemption, which Sultan observed. This commit adds a cond_resched() to the bottom of each loop iteration, so that these workers don't hog the core. Note that we don't need this on the napi poll worker, since that terminates after its budget is expended.

Donenfeld" Date: Wed, 6 May 2020 15:33:06 -0600 Subject: wireguard: send/receive: use explicit unlikely branch instead of implicit coalescing It's very unlikely that send will become true. It's nearly always false between 0 and 120 seconds of a session, and in most cases becomes true only between 120 and 121 seconds before becoming false again. So, unlikely(send) is clearly the right option here. What happened before was that we had this complex boolean expression with multiple likely and unlikely clauses nested. Since this is evaluated left-to-right anyway, the whole thing got converted to unlikely. So, we can clean this up to better represent what's going on. The generated code is the same.

The FLOW_ACTION_HW_STATS_DISABLED type explicitly requests the driver to disable the stats, however, if the driver cannot disable counters, it bails out. TCA_ACT_HW_STATS_* maintains the 1:1 mapping with FLOW_ACTION_HW_STATS_* except by disabled which is mapped to FLOW_ACTION_HW_STATS_DISABLED (this is 0 in tc).

This, unfortunately, does not take into account the ability of enabling "sig_enforce" on the boot command line (module.sig_enforce=1). Including the IMA module appraise rule results in failing the finit_module syscall, unless the module signing public key is loaded onto the IMA keyring. This patch fixes secure boot policy rules to be based on CONFIG_MODULE_SIG instead.

Tsirkin" Date: Thu, 7 May 2020 03:25:56 -0400 Subject: virtio_net: fix lockdep warning on 32 bit When we fill up a receive VQ, try_fill_recv currently tries to count kicks using a 64 bit stats counter. Turns out, on a 32 bit kernel that uses a seqcount. sequence counts are "lock" constructs where you need to make sure that writers are serialized. In turn, this means that we mustn't run two try_fill_recv concurrently. Which of course we don't. We do run try_fill_recv sometimes from a softirq napi context, and sometimes from a fully preemptible context, but the later always runs with napi disabled. However, when it comes to the seqcount, lockdep is trying to enforce the rule that the same lock isn't accessed from preemptible and softirq context - it doesn't know about napi being enabled/disabled. This causes a false-positive warning: WARNING: inconsistent lock state ... inconsistent {SOFTIRQ-ON-W} -> {IN-SOFTIRQ-W} usage. As a work around, shut down the warning by switching to u64_stats_update_begin_irqsave - that works by disabling interrupts on 32 bit only, is a NOP on 64 bit.

Mappings may happen at boot up, and if nothing synchronizes the page tables, those page mappings may not be synced till they are used. This causes issues for anything that might touch one of those mappings in the path of the page fault handler. When one of those unmapped mappings is touched in the page fault handler, it will cause another page fault, which in turn will cause a page fault, and leave us in a loop of page faults. Commit 763802b53a42 ("x86/mm: split vmalloc_sync_all()") split vmalloc_sync_all() into vmalloc_sync_unmappings() and vmalloc_sync_mappings(), as on system exit, it did not need to do a full sync on x86_64 (although it still needed to be done on x86_32). By chance, the vmalloc_sync_all() would synchronize the page mappings done at boot up and prevent the per cpu area from being a problem for tracing in the page fault handler. But when that synchronization in the exit of a task became a nop, it caused the problem to appear.

I managed to find a reproducer for this: ip li set bond0 up ifenslave bond0 eth0 brctl addbr br0 ethtool -K eth0 lro off brctl addif br0 bond0 ip li set br0 up When a NETDEV_FEAT_CHANGE event is triggered on a bonding slave, it captures this and calls bond_compute_features() to fixup its master's and other slaves' features. However, when syncing with its lower devices by netdev_sync_lower_features() this event is triggered again on slaves when the LRO feature fails to change, so it goes back and forth recursively until the kernel stack is exhausted. Commit 17b85d29e82c intentionally lets __netdev_update_features() return -1 for such a failure case, so we have to just rely on the existing check inside netdev_sync_lower_features() and skip NETDEV_FEAT_CHANGE event only for this specific failure case.

With that wakeup removed, if we add to ovflist here, we may never wake up. Rather than adding back the ep_scan_ready_list wakeup - which was resulting in unnecessary wakeups, trigger a wake-up in ep_poll_callback. We noticed that one of our workloads was missing wakeups starting with 339ddb53d373 and upon manual inspection, this wakeup seemed missing to me. With this patch added, we no longer see missing wakeups. I haven't yet tried to make a small reproducer, but the existing kselftests in filesystem/epoll passed for me with this patch.

That is safe in some contextes but not on others where allowing fs reclaim could lead to a deadlock because we are either holding some btrfs lock needed for a transaction commit or holding a btrfs transaction handle open. Because of that we surround the call to the function that initializes the percpu counter with a NOFS context using memalloc_nofs_save() (this is done at btrfs_init_fs_root()). However it turns out that this is not enough to prevent a possible deadlock because percpu_alloc() determines if it is in an atomic context by looking exclusively at the gfp flags passed to it (GFP_KERNEL in this case) and it is not aware that a NOFS context is set. Because percpu_alloc() thinks it is in a non atomic context it locks the pcpu_alloc_mutex. This can result in a btrfs deadlock when pcpu_balance_workfn() is running, has acquired that mutex and is waiting for reclaim, while the btrfs task that called percpu_counter_init() (and therefore percpu_alloc()) is holding either the btrfs commit_root semaphore or a transaction handle (done fs/btrfs/backref.c: iterate_extent_inodes()), which prevents reclaim from finishing as an attempt to commit the current btrfs transaction will deadlock.

Therefore this change makes pcpu_alloc() look up into an existing nofs/noio context before deciding whether it is in an atomic context or not.

Each thread can harvest only 1 event. 1 producer fires all 10 events at once and waits that all 10 events will be observed by 10 threads. In case of lost wakeup epoll_wait() will timeout and 0 will be returned. Test case catches two sort of problems: forgotten wakeup on event, which hits the ->ovflist list, this problem was fixed by: 5a2513239750 ("eventpoll: fix missing wakeup for ovflist in ep_poll_callback") the other problem is when several sequential events hit the same waiting thread, thus other waiters get no wakeups. Problem is fixed in the following patch.

The description of the problem is the following: if N (>1) threads are waiting on ep->wq for new events and M (>1) events come, it is quite likely that >1 wakeups hit the same wait queue entry, because there is quite a big window between __add_wait_queue_exclusive() and the following __remove_wait_queue() calls in ep_poll() function. This can lead to lost wakeups, because thread, which was woken up, can handle not all the events in ->rdllist. (in better words the problem is described here: https://lkml.org/lkml/2019/10/7/905) The idea of the current patch is to use init_wait() instead of init_waitqueue_entry(). Internally init_wait() sets autoremove_wake_function as a callback, which removes the wait entry atomically (under the wq locks) from the list, thus the next coming wakeup hits the next wait entry in the wait queue, thus preventing lost wakeups. Problem is very well reproduced by the epoll60 test case [1]. Wait entry removal on wakeup has also performance benefits, because there is no need to take a ep->lock and remove wait entry from the queue after the successful wakeup. Here is the timing output of the epoll60 test case: With explicit wakeup from ep_scan_ready_list() (the state of the code prior 339ddb53d373): real 0m6.970s user 0m49.786s sys 0m0.113s After this patch: real 0m5.220s user 0m36.879s sys 0m0.019s The other testcase is the stress-epoll [2], where one thread consumes all the events and other threads produce many events: With explicit wakeup from ep_scan_ready_list() (the state of the code prior 339ddb53d373): threads events/ms run-time ms 8 5427 1474 16 6163 2596 32 6824 4689 64 7060 9064 128 6991 18309 After this patch: threads events/ms run-time ms 8 5598 1429 16 7073 2262 32 7502 4265 64 7640 8376 128 7634 16767 (number of "events/ms" represents event bandwidth, thus higher is better; number of "run-time ms" represents overall time spent doing the benchmark, thus lower is better) [1] tools/testing/selftests/filesystems/epoll/epoll_wakeup_test.c [2] https://github.com/rouming/test-tools/blob/master/stress-epoll.c Signed-off-by: Roman Penyaev Signed-off-by: Andrew Morton Reviewed-by: Jason Baron Cc: Khazhismel Kumykov Cc: Alexander Viro Cc: Heiher Cc: Link: http://lkml.kernel.org/r/20200430130326.1368509-2-rpenyaev@suse.de Signed-off-by: Linus Torvalds --- fs/eventpoll.c | 43 ++++++++++++++++++++++++------------------- 1 file changed, 24 insertions(+), 19 deletions(-) diff --git a/fs/eventpoll.c b/fs/eventpoll.c index d6ba0e52439b..aba03ee749f8 100644 --- a/fs/eventpoll.c +++ b/fs/eventpoll.c @@ -1822,7 +1822,6 @@ static int ep_poll(struct eventpoll *ep, struct epoll_event __user *events, { int res = 0, eavail, timed_out = 0; u64 slack = 0; - bool waiter = false; wait_queue_entry_t wait; ktime_t expires, *to = NULL; @@ -1867,21 +1866,23 @@ fetch_events: */ ep_reset_busy_poll_napi_id(ep); - /* - * We don't have any available event to return to the caller.

On Arm64, with 64K pages and 512M huge pages, this is 8192 pages or 512M. It does this regardless of the number of managed pages managed in the zone or the likelihood of success. This can put the zone immediately under water in terms of allocating pages from the zone, and can cause a small machine to fail immediately due to OoM. Unlike set_recommended_min_free_kbytes(), which substantially increases min_free_kbytes and is tied to THP, boost_watermark() can be called even if THP is not active. The problem is most likely to appear on architectures such as Arm64 where pageblock_nr_pages is very large. It is desirable to run the kdump capture kernel in as small a space as possible to avoid wasting memory. In some architectures, such as Arm64, there are restrictions on where the capture kernel can run, and therefore, the space available. A capture kernel running in 768M can fail due to OoM immediately after boost_watermark() sets the min in zone DMA32, where most of the memory is, to 512M. It fails even though there is over 500M of free memory. With boost_watermark() suppressed, the capture kernel can run successfully in 448M. This patch limits boost_watermark() to boosting a zone's min watermark only when there are enough pages that the boost will produce positive results. In this case that is estimated to be four times as many pages as pageblock_nr_pages. Mel said: : There is no harm in marking it stable. Clearly it does not happen very : often but it's not impossible. 32-bit x86 is a lot less common now : which would previously have been vulnerable to triggering this easily. : ppc64 has a larger base page size but typically only has one zone. : arm64 is likely the most vulnerable, particularly when CMA is : configured with a small movable zone.

Nevertheless this patch fixes an issue with it. Commit ad73d6feadbd7b ("mmc: complete requests from ->timeout") preserved the existing functionality, to complete the request. However that had only been necessary because the block layer timeout handler had been marking the request to prevent it from being completed normally. That restriction was removed at the same time, the result being that a request that has gone will have been completed anyway. That is, the completion was unnecessary. At the time, the unnecessary completion was harmless because the block layer would ignore it, although that changed in kernel v5.0.

Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] sizeof(flexible-array-member) triggers a warning because flexible array members have incomplete type[1]. There are some instances of code in which the sizeof operator is being incorrectly/erroneously applied to zero-length arrays and the result is zero. Such instances may be hiding some bugs.

On Intel, #DB exceptions transmit the DR6 value via the exit qualification field of the VMCS, and the exit qualification only contains the description of the precise event that caused a vmexit. On AMD, instead the DR6 field of the VMCB is filled in as if the #DB exception was to be injected into the guest. This has two effects when guest debugging is in use: * the guest DR6 is clobbered * the kvm_run->debug.arch.dr6 field can accumulate more debug events, rather than just the last one that happened (the testcase in the next patch covers this issue). This patch fixes both issues by emulating, so to speak, the Intel behavior on AMD processors. The important observation is that (after the previous patches) the VMCB value of DR6 is only ever observable from the guest is KVM_DEBUGREG_WONT_EXIT is set. Therefore we can actually set vmcb->save.dr6 to any value we want as long as KVM_DEBUGREG_WONT_EXIT is clear, which it will be if guest debugging is enabled. Therefore it is possible to enter the guest with an all-zero DR6, reconstruct the #DB payload from the DR6 we get at exit time, and let kvm_deliver_exception_payload move the newly set bits into vcpu->arch.dr6. Some extra bits may be included in the payload if KVM_DEBUGREG_WONT_EXIT is set, but this is harmless. This may not be the most optimized way to deal with this, but it is simple and, being confined within SVM code, it gets rid of the set_dr6 callback and kvm_update_dr6.

However, in single-user cases with lock_nolock, there are no other nodes to recover the journal. Function signal_our_withdraw() was recognizing the lock_nolock situation, but not until after it had evicted its journal inode. Since the journal descriptor that points to the inode was never removed from the master list, when the unmount occurred, it did another iput on the evicted inode, which resulted in a BUG_ON(inode->i_state & I_CLEAR). This patch moves the check for this situation earlier in function signal_our_withdraw(), which avoids the extra iput, so the unmount may happen normally.

The whole story is a little longer. The legacy clone() syscall is odd in a bunch of ways and here two things interact. First, legacy clone's flag argument is word-size dependent, i.e. it's an unsigned long whereas most system calls with flag arguments use int or unsigned int. Second, legacy clone() ignores unknown and deprecated flags. The two of them taken together means that users on 64bit systems can pass garbage for the upper 32bit of the clone() syscall since forever and things would just work fine. Just try this on a 64bit kernel prior to v5.7-rc1 where this will succeed and on v5.7-rc1 where this will fail with EBADF: int main(int argc, char *argv[]) { pid_t pid; /* Note that legacy clone() has different argument ordering on * different architectures so this won't work everywhere. * * Only set the upper 32 bits. */ pid = syscall(__NR_clone, 0xffffffff00000000 | SIGCHLD, NULL, NULL, NULL, NULL); if (pid < 0) exit(EXIT_FAILURE); if (pid == 0) exit(EXIT_SUCCESS); if (wait(NULL) != pid) exit(EXIT_FAILURE); exit(EXIT_SUCCESS); } Since legacy clone() couldn't be extended this was not a problem so far and nobody really noticed or cared since nothing in the kernel ever bothered to look at the upper 32 bits. But once we introduced clone3() and expanded the flag argument in struct clone_args to 64 bit we opened this can of worms. With the first flag-based extension to clone3() making use of the upper 32 bits of the flag argument we've effectively made it possible for the legacy clone() syscall to reach clone3() only flags. The sign extension scenario is just the odd corner-case that we needed to figure this out. The reason we just realized this now and not already when we introduced CLONE_CLEAR_SIGHAND was that CLONE_INTO_CGROUP assumes that a valid cgroup file descriptor has been given. So the sign extension (or the user accidently passing garbage for the upper 32 bits) caused the CLONE_INTO_CGROUP bit to be raised and the kernel to error out when it didn't find a valid cgroup file descriptor. Let's fix this by always capping the upper 32 bits for all codepaths that are not aware of clone3() features. This ensures that we can't reach clone3() only features by accident via legacy clone as with the sign extension case and also that legacy clone() works exactly like before, i.e. ignoring any unknown flags. This solution risks no regressions and is also pretty clean.

R. Silva" Date: Thu, 7 May 2020 13:56:08 -0500 Subject: tools/testing: Replace zero-length array with flexible-array The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] sizeof(flexible-array-member) triggers a warning because flexible array members have incomplete type[1]. There are some instances of code in which the sizeof operator is being incorrectly/erroneously applied to zero-length arrays and the result is zero. Such instances may be hiding some bugs. So, this work (flexible-array member conversions) will also help to get completely rid of those sorts of issues. This issue was found with the help of Coccinelle.

That kept the glock locked, so it could not be given away, which correctly avoids file system corruption. However, it never set the withdraw bit or requeueing the glock work. So it would hang forever, unable to ever demote the glock. This patch changes to goto to a new label, skip_inval, so that errors from go_sync are treated the same way as errors from go_inval: The delayed withdraw bit is set and the work is requeued. That way, the logd should eventually figure out there's a problem and withdraw properly there.

This patch fixes a regression: patch df5db5f9ee112 allowed function run_queue() to bypass its call to do_xmote() if revokes were queued for the glock. That's wrong because its call to do_xmote() is what is responsible for calling the go_sync() glops functions to sync both the ail list and any revokes queued for it. By bypassing the call, gfs2 could get into a stand-off where the glock could not be demoted until its revokes are written back, but the revokes would not be written back because do_xmote() was never called. It "sort of" works, however, because there are other mechanisms like the log flush daemon (logd) that can sync the ail items and revokes, if it deems it necessary. The problem is: without file system pressure, it might never deem it necessary.

The implementation in DM was previously correct *before* we started sending vblank events from VSTARTUP unconditionally to handle cases where HUBP was off, OTG was ON and userspace was still requesting some DRM planes enabled. As part of that patch series we dropped VUPDATE since it was deemed close enough to VSTARTUP, but there's a key difference betweeen VSTARTUP and VUPDATE - the VUPDATE signal can be blocked if we're holding the pipe lock. There was a fix recently to revert the unconditional behavior for the DCN VSTARTUP vblank event since it was sending the pageflip event on the wrong frame - once again, due to blocking VUPDATE and having the address start scanning out two frames later. The problem with this fix is it didn't update the logic that calls drm_crtc_handle_vblank(), so the timestamps are totally bogus now. [How] Essentially reverts most of the original VSTARTUP series but retains the behavior to send back events when active planes == 0. Some refactoring/cleanup was done to not have duplicated code in both the handlers.

One of the callers was inside nfs_fscache_get_super_cookie() and was changed to use the full struct nfs_fscache_key as the index_key. However, a couple members of this structure contain pointers and thus will change each time the same NFS share is remounted. Since index_key is used for fscache_cookie->key_hash and this subsequently is used to compare cookies, the effectiveness of fscache with NFS is reduced to the point at which a umount occurs. Any subsequent remount of the same share will cause a unique NFS super_block index_key and key_hash to be generated for the same data, rendering any prior fscache data unable to be found. A simple reproducer demonstrates the problem. 1. Mount share with 'fsc', create a file, drop page cache systemctl start cachefilesd mount -o vers=3,fsc 127.0.0.1:/export /mnt dd if=/dev/zero of=/mnt/file1.bin bs=4096 count=1 echo 3 > /proc/sys/vm/drop_caches 2. Read file into page cache and fscache, then unmount dd if=/mnt/file1.bin of=/dev/null bs=4096 count=1 umount /mnt 3.

Check for READ ops in mountstats - there should be none grep READ: /proc/self/mountstats Looking at the history and the removed function, nfs_super_get_key(), we should only use nfs_fscache_key.key plus any uniquifier, for the fscache index_key.

The problem can be seen easily on a heavy loaded system (for example many processes reading files continually on an NFS share covered by fscache triggered this problem within a few minutes). The race is due to cachefiles_read_waiter() adding the op to the monitor to_do list and then then drop the object->work_lock spinlock before completing fscache_enqueue_operation().

Since rate_tokens is cleared after a redirect silence, and never incremented on redirects, if the host keeps receiving packets requiring redirect it will reply ignoring the backoff. Additionally, the 'rate_last' field will be updated with the cadence of the ingress packet requiring redirect. If that rate is high enough, that will prevent the host from generating any other kind of ICMP messages The check for a zero 'rate_tokens' value was likely a shortcut to avoid the more complex backoff algorithm after a redirect silence period.

This can cause odd behavior where we never reclaim all the trbs in the sg list, so we never call giveback on a usb req, and that will causes transfer stalls. This effectively resovles the adb stalls seen on HiKey960 after userland changes started only using AIO in adbd.

For example, we consider it unreliable for gcc versions < 4.9, but also if -O3 is enabled, or if optimizing for size. And then various kernel config options disabled it, because they know that they trigger that warning by confusing gcc sufficiently (ie PROFILE_ALL_BRANCHES). And now gcc-10 seems to be introducing a lot of those warnings too, so it falls under the same heading as 4.9 did. At the same time, we have a very straightforward way to _enable_ that warning when wanted: use "W=2" to enable more warnings. So stop playing these ad-hoc games, and just disable that warning by default, with the known and straight-forward "if you want to work on the extra compiler warnings, use W=123". Would it be great to have code that is always so obvious that it never confuses the compiler whether a variable is used initialized or not? Yes, it would. In a perfect world, the compilers would be smarter, and our source code would be simpler. That's currently not the world we live in, though.

Yes, they are getting converted to flexible arrays, but in the meantime the gcc-10 warning about zero-length bounds is very verbose, and is hiding other issues. I missed one actual build failure because it was hidden among hundreds of lines of warning. Thankfully I caught it on the second go before pushing things out, but it convinced me that I really need to disable the new warnings for now. We'll hopefully be all done with our conversion to flexible arrays in the not too distant future, and we can then re-enable this warning.

Because C didn't historically support flexible array members, we have code that instead uses a one-sized array, the same way we have cases of zero-sized arrays. The one-sized arrays come from either not wanting to use the gcc zero-sized array extension, or from a slight convenience-feature, where particularly for strings, the size of the structure now includes the allocation for the final NUL character. So with a "char name[1];" at the end of a structure, you can do things like v = my_malloc(sizeof(struct vendor) + strlen(name)); and avoid the "+1" for the terminator. Yes, the modern way to do that is with a flexible array, and using 'offsetof()' instead of 'sizeof()', and adding the "+1" by hand. That also technically gets the size "more correct" in that it avoids any alignment (and thus padding) issues, but this is another long-term cleanup thing that will not happen for 5.7. So disable the warning for now, even though it's potentially quite useful. Having a slew of warnings that then hide more urgent new issues is not an improvement.

That's actually a great warning, and if we ever start using 'restrict' in the kernel, it might be quite useful. But right now we don't, and it turns out that the only thing this warns about is an idiom where we have declared a few functions to be "printf-like" (which seems to make gcc pick up the restricted pointer thing), and then we print to the same buffer that we also use as an input. And people do that as an odd concatenation pattern, with code like this: #define sysfs_show_gen_prop(buffer, fmt, ...) \ snprintf(buffer, PAGE_SIZE, "%s"fmt, buffer, __VA_ARGS__) where we have 'buffer' as both the destination of the final result, and as the initial argument. Yes, it's a bit questionable. And outside of the kernel, people do have standard declarations like int snprintf( char *restrict buffer, size_t bufsz, const char *restrict format, ... ); where that output buffer is marked as a restrict pointer that cannot alias with any other arguments. But in the context of the kernel, that 'use snprintf() to concatenate to the end result' does work, and the pattern shows up in multiple places. And we have not marked our own version of snprintf() as taking restrict pointers, so the warning is incorrect for now, and gcc picks it up on its own. If we do start using 'restrict' in the kernel (and it might be a good idea if people find places where it matters), we'll need to figure out how to avoid this issue for snprintf and friends. But in the meantime, this warning is not useful.

This results in warnings like: crypto/xts.c:325:13: warning: conflicting types for built-in function ‘free’; expected ‘void(void *)’ [-Wbuiltin-declaration-mismatch] because the crypto layer had its local freeing functions called 'free()'. Gcc-10 is in the wrong here, since that function is marked 'static', and thus there is no chance of confusion with any standard library function namespace. But the simplest thing to do is to just use a different name here, and avoid this gcc mis-feature. [ Side note: gcc knowing about 'free()' is in itself not the mis-feature: the semantics of 'free()' are special enough that a compiler can validly do special things when seeing it. So the mis-feature here is that gcc thinks that 'free()' is some restricted name, and you can't shadow it as a local static function. Making the special 'free()' semantics be a function attribute rather than tied to the name would be the much better model ] Signed-off-by: Linus Torvalds --- crypto/lrw.c | 6 +++--- crypto/xts.c | 6 +++--- 2 files changed, 6 insertions(+), 6 deletions(-) diff --git a/crypto/lrw.c b/crypto/lrw.c index 376d7ed3f1f8..3c734b81b3a2 100644 --- a/crypto/lrw.c +++ b/crypto/lrw.c @@ -287,7 +287,7 @@ static void exit_tfm(struct crypto_skcipher *tfm) crypto_free_skcipher(ctx->child); } -static void free(struct skcipher_instance *inst) +static void free_inst(struct skcipher_instance *inst) { crypto_drop_skcipher(skcipher_instance_ctx(inst)); kfree(inst); @@ -400,12 +400,12 @@ static int create(struct crypto_template *tmpl, struct rtattr **tb) inst->alg.encrypt = encrypt; inst->alg.decrypt = decrypt; - inst->free = free; + inst->free = free_inst; err = skcipher_register_instance(tmpl, inst); if (err) { err_free_inst: - free(inst); + free_inst(inst); } return err; } diff --git a/crypto/xts.c b/crypto/xts.c index dbdd8af629e6..6d8cea94b3cf 100644 --- a/crypto/xts.c +++ b/crypto/xts.c @@ -322,7 +322,7 @@ static void exit_tfm(struct crypto_skcipher *tfm) crypto_free_cipher(ctx->tweak); } -static void free(struct skcipher_instance *inst) +static void free_inst(struct skcipher_instance *inst) { crypto_drop_skcipher(skcipher_instance_ctx(inst)); kfree(inst); @@ -434,12 +434,12 @@ static int create(struct crypto_template *tmpl, struct rtattr **tb) inst->alg.encrypt = encrypt; inst->alg.decrypt = decrypt; - inst->free = free; + inst->free = free_inst; err = skcipher_register_instance(tmpl, inst); if (err) { err_free_inst: - free(inst); + free_inst(inst); } return err; } -- cgit v1.2.3-59-g8ed1b From e99332e7b4cda6e60f5b5916cf9943a79dbef902 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Sat, 9 May 2020 17:50:03 -0700 Subject: gcc-10: mark more functions __init to avoid section mismatch warnings It seems that for whatever reason, gcc-10 ends up not inlining a couple of functions that used to be inlined before. Even if they only have one single callsite - it looks like gcc may have decided that the code was unlikely, and not worth inlining. The code generation difference is harmless, but caused a few new section mismatch errors, since the (now no longer inlined) function wasn't in the __init section, but called other init functions: Section mismatch in reference from the function kexec_free_initrd() to the function .init.text:free_initrd_mem() Section mismatch in reference from the function tpm2_calc_event_log_size() to the function .init.text:early_memremap() Section mismatch in reference from the function tpm2_calc_event_log_size() to the function .init.text:early_memunmap() So add the appropriate __init annotation to make modpost not complain.

If the task does some network thing then the v2 cgroup can never be freed after the session exited. One of our machines ran into OOM due to this memory leak. In the scenario described above when sk_alloc() is called cgroup_sk_alloc() thought it's in v2 mode, so it stores the cgroup pointer in sk->sk_cgrp_data and increments the cgroup refcnt, but then sock_update_netprioidx() thought it's in v1 mode, so it stores netprioidx value in sk->sk_cgrp_data, so the cgroup refcnt will never be freed. Currently we do the mode switch when someone writes to the ifpriomap cgroup control file. The easiest fix is to also do the switch when a task is attached to a new cgroup.

Wysocki" Date: Sat, 9 May 2020 10:44:41 +0200 Subject: ACPI: EC: PM: Avoid premature returns from acpi_s2idle_wake() If the EC GPE status is not set after checking all of the other GPEs, acpi_s2idle_wake() returns 'false', to indicate that the SCI event that has just triggered is not a system wakeup one, but it does that without canceling the pending wakeup and re-arming the SCI for system wakeup which is a mistake, because it may cause s2idle_loop() to busy spin until the next valid wakeup event. [If that happens, the first spurious wakeup is still pending after acpi_s2idle_wake() has returned, so s2idle_enter() does nothing, acpi_s2idle_wake() is called again and it sees that the SCI has triggered, but no GPEs are active, so 'false' is returned again, and so on.] Fix that by moving all of the GPE checking logic from acpi_s2idle_wake() to acpi_ec_dispatch_gpe() and making the latter return 'true' only if a non-EC GPE has triggered and 'false' otherwise, which will cause acpi_s2idle_wake() to cancel the pending SCI wakeup and re-arm the SCI for system wakeup regardless of the EC GPE status. This also addresses a lockup observed on an Elitegroup EF20EA laptop after attempting to wake it up from suspend-to-idle by a key press.

This can cause problems with some fileservers with calls to the cache manager in the afs filesystem being dropped from the fileserver because a packet goes missing and the retransmission timeout is greater than the call expiry timeout. Fix this by: (1) Copying the RTT/RTO calculation code from Linux's TCP implementation and altering it to fit rxrpc. (2) Altering the various users of the RTT to make use of the new SRTT value. (3) Replacing the use of rxrpc_resend_timeout to use the calculated RTO value instead (which is needed in jiffies), along with a backoff. Notes: (1) rxrpc provides RTT samples by matching the serial numbers on outgoing DATA packets that have the RXRPC_REQUEST_ACK set and PING ACK packets against the reference serial number in incoming REQUESTED ACK and PING-RESPONSE ACK packets. (2) Each packet that is transmitted on an rxrpc connection gets a new per-connection serial number, even for retransmissions, so an ACK can be cross-referenced to a specific trigger packet. This allows RTT information to be drawn from retransmitted DATA packets also. (3) rxrpc maintains the RTT/RTO state on the rxrpc_peer record rather than on an rxrpc_call because many RPC calls won't live long enough to generate more than one sample. (4) The calculated SRTT value is in units of 8ths of a microsecond rather than nanoseconds. The (S)RTT and RTO values are displayed in /proc/net/rxrpc/peers.

When support for clashing entries was added, the assumption that all nf_conn objects are added twice, once in original, once for reply tuple no longer holds -- NF_CLASH_BIT entries are only added in the non-clashing reply direction. Thus, if at least one NF_CLASH entry is in the list then nf_conntrack_cleanup_net_list() always skips it completely. During normal netns destruction, this causes a hang of several seconds, until the gc worker removes the entry (NF_CLASH entries always have a 1 second timeout). But in the rmmod case, the gc worker has already been stopped, so ct.count never becomes 0. We can fix this in two ways: 1. Add a second test for CLASH_BIT and call iterator for those entries as well, or: 2. Skip the original tuple direction and use the reply tuple. 2) is simpler, so do that.

The fix for this was to call kthread_stop() after creating the thread to make sure it finishes before allowing the module to be removed. Now this caused the opposite problem on fast machines. What now happens is the kthread_stop() can cause the kthread never to execute and the test never to run. To fix this, add a completion and wait for the kthread to execute, then wait for it to end. This issue caused the ftracetest selftests to fail on the preemptirq tests.

It however missed another case. user_sdma_send_pkts() has two calls from hfi1_user_sdma_process_request(). If the first one fails as indicated by -EBUSY, the pq will be placed on the waitlist as by design. If the second call then succeeds, the pq is still on the waitlist setting up a race with the interrupt handler if a subsequent request uses a different SDMA engine Fix by deleting the first call. The use of pcount and the intent to send a short burst of packets followed by the larger balance of packets was never correctly implemented, because the two calls always send pcount packets no matter what. A subsequent patch will correct that issue.

Initially, the pkey cache pointer is NULL. ib_cache_update allocates a buffer and populates it with the device's pkeys, via repeated calls to procedure ib_query_pkey(). If there is a failure in populating the pkey buffer via ib_query_pkey(), ib_cache_update does not replace the old pkey buffer cache with the updated one -- it leaves the old cache as is. Since initially the pkey buffer cache is NULL, when calling ib_cache_update the first time, a failure in ib_query_pkey() will cause the pkey buffer cache pointer to remain NULL. In this situation, any calls subsequent to ib_get_cached_pkey(), ib_find_cached_pkey(), or ib_find_cached_pkey_exact() will try to dereference the NULL pkey cache pointer, causing a kernel panic. Fix this by checking the ib_cache_update() return value.

R. Silva" Date: Mon, 11 May 2020 12:46:47 -0500 Subject: ASoC: Intel: Skylake: Replace zero-length array with flexible-array The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] sizeof(flexible-array-member) triggers a warning because flexible array members have incomplete type[1]. There are some instances of code in which the sizeof operator is being incorrectly/erroneously applied to zero-length arrays and the result is zero. Such instances may be hiding some bugs. So, this work (flexible-array member conversions) will also help to get completely rid of those sorts of issues. This issue was found with the help of Coccinelle.

While at that, we can initialize the snd_dmaengine_dai_dma_data structures earlier. Let's also stop offsetting the source/destination of the DMA transfer by phys_base.

That's because TI_CPTS_MOD (which is the symbol gating the _compilation_ of cpts.c) now depends on PTP_1588_CLOCK, and so is not enabled in these configurations, but TI_CPTS (which is the symbol gating _calls_ to the cpts functions) _is_ enabled. So we end up compiling calls to functions that don't exist, resulting in the linker errors. This patch fixes build errors and restores previous behavior by: - ensure PTP_1588_CLOCK=y in TI specific configs and CPTS will be built - remove TI_CPTS_MOD and, instead, add dependencies from CPTS in TI_CPSW/TI_KEYSTONE_NETCP/TI_CPSW_SWITCHDEV as below: config TI_CPSW_SWITCHDEV ... depends on TI_CPTS || !TI_CPTS which will ensure proper dependencies PTP_1588_CLOCK -> TI_CPTS -> TI_CPSW/TI_KEYSTONE_NETCP/TI_CPSW_SWITCHDEV and build type selection. Note. For NFS boot + CPTS all of above configs have to be built-in.

However, when ib_uverbs_free_hw_resources() pushes IB_EVENT_DEVICE_FATAL and then immediately goes to destroy all uobjects this causes ib_uverbs_free_event_queue() to discard the queued event if userspace hasn't already read() it. Unlike all other event queues async FD needs to defer the ib_uverbs_free_event_queue() until FD release. This still unregisters the handler from the IB device during disassociation.

The cause is the "ftrace=function" would register the function tracer and create a trampoline, and it will set it as executable and read-only. Then the "trace_options=func_stack_trace" would then update the same trampoline to include the stack tracer version of the function tracer. But since the trampoline already exists, it updates it with text_poke_bp(). The problem is that text_poke_bp() called while system_state == SYSTEM_BOOTING, it will simply do a memcpy() and not the page mapping, as it would think that the text is still read-write. But in this case it is not, and we take a fault and crash. Instead, lets keep the ftrace trampolines read-write during boot up, and then when the kernel executable text is set to read-only, the ftrace trampolines get set to read-only as well.

As a result of this invalid configuration, Jetson TK1 fails to resume from suspend. This used to get papered over because the ASoC driver would force audio clocks to a 44.1 kHz configuration on boot. However, that's not really necessary and was hence removed in commit ff5d18cb04f4 ("ASoC: tegra: Enable audio mclk during tegra_asoc_utils_init()").

In do_handle_to_path() we know that "handle->handle_bytes" is non-zero and we do: handle_dwords = handle->handle_bytes >> 2; So values 1-3 become zero. Then in ovl_fh_to_dentry() we do: int len = fh_len << 2; So now len is in the "0,4-128" range and a multiple of 4. But if "buflen" is zero it will try to copy negative bytes when we do the memcpy in ovl_fid_to_fh(). memcpy(&fh->fb, fid, buflen - OVL_FH_WIRE_OFFSET); And that will lead to a crash.

Both of those are bugs: the entry is likely to be shorter than 255 bytes, and zero-termination is not guaranteed. With Acer SF314-42 firmware these issues manifest visibly in dmesg: AMD-Vi: ivrs, add hid:AMDI0020, uid:\_SB.FUR0\xf0\xa5, rdevid:160 AMD-Vi: ivrs, add hid:AMDI0020, uid:\_SB.FUR1\xf0\xa5, rdevid:160 AMD-Vi: ivrs, add hid:AMDI0020, uid:\_SB.FUR2\xf0\xa5, rdevid:160 AMD-Vi: ivrs, add hid:AMDI0020, uid:\_SB.FUR3>\x83e\x8d\x9a\xd1... The first three lines show how the code over-reads adjacent table entries into the UID, and in the last line it even reads garbage data beyond the end of the IVRS table itself. Since each entry has the length of the UID (uidl member of ivhd_entry struct), use that for memcpy, and manually add a zero terminator. Avoid zero-filling hid and uid arrays up front, and instead ensure the uid array is always zero-terminated. No change needed for the hid array, as it was already properly zero-terminated.

It can be read with XSAVE and written with XRSTOR. So, if we don't set the guest PKRU value here(kvm_load_guest_xsave_state), the guest can read the host value. In case of kvm_load_host_xsave_state, guest with CR4.PKE clear could potentially use XRSTOR to change the host PKRU value.

However, on the receiving side, the ACK is issued only when application really reads the whole data. Even if part of the last buffer is received, we will not do the ACK as required. This might cause an unnecessary delay since the receiver does not always fetch the message as fast as the sender, resulting in a large latency in the user message sending, which is: [one RTT + the receiver processing time]. The commit makes Nagle ACK as soon as possible i.e. when a message with the 'ack_required' arrives in the receiving side's stack even before it is processed or put in the socket receive queue... This way, we can limit the streaming latency to one RTT as committed in Nagle mode. Acked-by: Ying Xue Acked-by: Jon Maloy Signed-off-by: Tuong Lien Signed-off-by: David S.

Also, in case of any failure, the connection will be shutdown and all the pertaining 'sub' objects will be freed. However, there is a race condition as follows resulting in memory leak: receive-work connection send-work | | | sub-1 |<------//-------| | sub-2 |<------//-------| | | |<---------------| evt for sub-x sub-3 |<------//-------| | : : : : : : | /--------| | | | * peer closed | | | | | | | |<-------X-------| evt for sub-y | | |<===============| sub-n |<------/ X shutdown | -> orphan | | That is, the 'receive-work' may get the last subscription request while the 'send-work' is shutting down the connection due to peer close. We had a 'lock' on the connection, so the two actions cannot be carried out simultaneously. If the last subscription is allocated e.g. 'sub-n', before the 'send-work' closes the connection, there will be no issue at all, the 'sub' objects will be freed. In contrast the last subscription will become orphan since the connection was closed, and we released all references. This commit fixes the issue by simply adding one test if the connection remains in 'connected' state right after we obtain the connection lock, then a subscription object can be created as usual, otherwise we ignore it.

However, there are two issues in code that can cause such an unused subscription to persist: 1) The 'tipc_conn_delete_sub()' has a loop on the subscription list but it makes a break shortly when the 1st subscription differs from the one specified, so the subscription will not be deleted. 2) In case a subscription is canceled, the code to remove the 'TIPC_SUB_CANCEL' flag from the subscription filter does not work if it is a local subscription (i.e. the little endian isn't involved). So, it will be no matches when looking for the subscription to delete later. The subscription(s) will be removed eventually when the user terminates its topology connection but that could be a long time later. Meanwhile, the number of available subscriptions may be exhausted. This commit fixes the two issues above, so as needed a subscription can be deleted correctly. Acked-by: Ying Xue Acked-by: Jon Maloy Signed-off-by: Tuong Lien Signed-off-by: David S.

This avoids allocation of a buffer and return of the full EFI memory map, which is not needed here and would otherwise need to be freed. Routine allocate_e820() only needs to know how many EFI memory descriptors there are in the map to allocate an adequately sized e820ext buffer, if it's needed. Note that since efi_get_memory_map() returns a memory map buffer sized with extra headroom, allocate_e820() now needs to explicitly factor that into the e820ext size calculation.

Raw Gadget tries iterating over the list of available endpoints and finding one that has the right direction and transfer type. Unfortunately selecting arbitrary gadget endpoints (even if they satisfy feature requirements) doesn't work, as (depending on the UDC driver) they might have fixed addresses, and one also needs to provide matching endpoint addresses in the descriptors sent to the host. The composite framework deals with this by assigning endpoint addresses in usb_ep_autoconfig() before enumeration starts. This approach won't work with Raw Gadget as the endpoints are supposed to be enabled after a set_configuration/set_interface request from the host, so it's too late to patch the endpoint descriptors that had already been sent to the host. For Raw Gadget we take another approach. Similarly to GadgetFS, we allow the user to make the decision as to which gadget endpoints to use. This patch adds another Raw Gadget ioctl USB_RAW_IOCTL_EPS_INFO that exposes information about all non-control endpoints that a currently connected UDC has. This information includes endpoints addresses, as well as their capabilities and limits to allow the user to choose the most fitting gadget endpoint. The USB_RAW_IOCTL_EP_ENABLE ioctl is updated to use the proper endpoint validation routine usb_gadget_ep_match_desc(). These changes affect the portability of the gadgets that use Raw Gadget when running on different UDCs. Nevertheless, as long as the user relies on the information provided by USB_RAW_IOCTL_EPS_INFO to dynamically choose endpoint addresses, UDC-agnostic gadgets can still be written with Raw Gadget.

This causes a warning and deactivation of the ring buffer code. Looking at the other cases of failure to get an event, it appears that there's a chance that the writer could cause them too. Since the iterator is a "best effort" to read the ring buffer if there's an active writer (the consumer reader is made for this case "see trace_pipe"), if it fails to get an event after three tries, simply give up and return NULL. Don't warn, nor disable the ring buffer on this failure.

What arch/sky/lib/usercopy.c is doing is broken - it can lead to e.g. data corruption on write(2). raw_copy_to_user() is inaccurate about return value, which is a bug, but consequences are less drastic than for raw_copy_from_user(). And just what are those access_ok() doing in there? I mean, look into linux/uaccess.h; that's where we do that check (as well as zero tail on failure in the callers that need zeroing). AFAICS, all of that shouldn't be hard to fix; something like a patch below might make a useful starting point. I would suggest moving these macros into usercopy.c (they are never used anywhere else) and possibly expanding them there; if you leave them alive, please at least rename __copy_user_zeroing(). Again, it must not zero anything on failed read. Said that, I'm not sure we won't be better off simply turning usercopy.c into usercopy.S - all that is left there is a couple of functions, each consisting only of inline asm. Guo Ren reply: Yes, raw_copy_from_user is wrong, it's no need zeroing code. unsigned long _copy_from_user(void *to, const void __user *from, unsigned long n) { unsigned long res = n; might_fault(); if (likely(access_ok(from, n))) { kasan_check_write(to, n); res = raw_copy_from_user(to, from, n); } if (unlikely(res)) memset(to + (n - res), 0, res); return res; } EXPORT_SYMBOL(_copy_from_user); You are right and access_ok() should be removed. but, how about: do { ...

It's just that copy_to_user() and friends are on fairly hot codepaths, and in quite a few situations they will dominate the speed of e.g. read(2). So I tried to keep the fast path unchanged. Up to the architecture maintainers, obviously. Which would be you... As for the fixups size increase (__ex_table size is unchanged)... You have each of those macros expanded exactly once. So the size is not a serious argument, IMO - useless complexity would be, if it is, in fact, useless; the size... not really, especially since those extra subi will at least offset it. Again, up to you - asm optimizations of (essentially) memcpy()-style loops are tricky and can depend upon the fairly subtle details of architecture. So even on something I know reasonably well I would resort to direct experiments if I can't pass the buck to architecture maintainers.

But oom_kill event is a special one as it is used in both cgroup1 and cgroup2. In cgroup1, it is displayed in memory.oom_control. The file memory.oom_control is in both root memcg and non root memcg, that is different with memory.event as it only in non-root memcg. That commit is okay for cgroup2, but it is not okay for cgroup1 as it will cause inconsistent behavior between root memcg and non-root memcg. Here's an example on why this behavior is inconsistent in cgroup1. root memcg / memcg foo / memcg bar Suppose there's an oom_kill in memcg bar, then the oon_kill will be root memcg : memory.oom_control(oom_kill) 0 / memcg foo : memory.oom_control(oom_kill) 1 / memcg bar : memory.oom_control(oom_kill) 1 For the non-root memcg, its memory.oom_control(oom_kill) includes its descendants' oom_kill, but for root memcg, it doesn't include its descendants' oom_kill. That means, memory.oom_control(oom_kill) has different meanings in different memcgs. That is inconsistent. Then the user has to know whether the memcg is root or not. If we can't fully support it in cgroup1, for example by adding memory.events.local into cgroup1 as well, then let's don't touch its original behavior.

It is quite likely that ep_events_available() observes empty lists and goes to sleep. Since commit 339ddb53d373 ("fs/epoll: remove unnecessary wakeups of nested epoll") we are conservative in wakeups (there is only one place for wakeup and this is ep_poll_callback()), thus ep_events_available() must always observe correct state of two lists. The easiest and correct way is to do the final check under the lock. This does not impact the performance, since lock is taken anyway for adding a wait entry to the wait queue. The discussion of the problem can be found here: https://lore.kernel.org/linux-fsdevel/a2f22c3c-c25a-4bda-8339-a7bdaf17849e@akamai.com/ In this patch barrierless __set_current_state() is used. This is safe since waitqueue_active() is called under the same lock on wakeup side. Short-circuit for fatal signals (i.e. fatal_signal_pending() check) is moved to the line just before actual events harvesting routine. This is fully compliant to what is said in the comment of the patch where the actual fatal_signal_pending() check was added: c257a340ede0 ("fs, epoll: short circuit fetching events if thread has been killed").

When we get the 2nd+ retry, we'll be with TRIED flag set. Current code will bail out on the 2nd retry because the !TRIED check will fail so the retry logic will be skipped. What's worse is that, it will also return zero which errornously hints the caller that the page is faulted in while it's not. The !TRIED flag check seems to not be needed even before the mutliple retries change because if we get a VM_FAULT_RETRY, it must be the 1st retry, and we should not have TRIED set for that. Fix it by removing the !TRIED check, at the meantime check against fatal signals properly before the page fault so we can still properly respond to the user killing the process during retries.

This patch also explicitly added return value checking for tracing/raw_tp, tracing/fmod_ret, and freplace programs such that these program return values can be anything. The purpose are two folds: 1. to make it explicit about return value expectations for these programs in verifier. 2. for tracing prog_type, if a future attach type is added, the default is -ENOTSUPP which will enforce to specify return value ranges explicitly.

The new pcistb_mio/pcstg_mio/pcilg_mio instructions are executed similiarly to normal load/store instructions and do address translation in the current address space. That means inside the kernel they are aware of mappings into kernel address space while outside the kernel they use user space mappings (usually created through mmap'ing a PCI device file). Now when existing user space applications use the s390_pci_mmio_write and s390_pci_mmio_read syscalls, they pass I/O addresses that are mapped into user space so as to be usable with the new instructions without needing a syscall. Accessing these addresses with the old instructions as done currently leads to a kernel panic. Also, for such a user space mapping there may not exist an equivalent kernel space mapping which means we can't just use the new instructions in kernel space. Instead of replicating user mappings in the kernel which then might collide with other mappings, we can conceptually execute the new instructions as if executed by the user space application using the secondary address space. This even allows us to directly store to the user pointer without the need for copy_to/from_user().

This scenario arises very reliably when using persistent handles and a reconnect occurs while writing. cifs_writev_requeue only releases the reference if the write fails (rc != 0).

The rm command hangs in transport_clear_lun_ref() at wait_for_completion(&lun->lun_shutdown_comp) The reason is, that transport_lun_remove_cmd() is not called at the end of target_tmr_work(). It seems, that in other fabrics this call happens implicitly when the fabric drivers call transport_generic_free_cmd() during their ->queue_tm_rsp(). Unfortunately Loopback seems to not comply to the common way of calling transport_generic_free_cmd() from ->queue_*(). Instead it calls transport_generic_free_cmd() from its ->check_stop_free() only. But the ->check_stop_free() is called by transport_cmd_check_stop_to_fabric() after it has reset the se_cmd->se_lun pointer. Therefore the following transport_generic_free_cmd() skips the transport_lun_remove_cmd(). So this patch re-adds the transport_lun_remove_cmd() at the end of target_tmr_work(), which was removed during commit 2c9fa49e100f ("scsi: target/core: Make ABORT and LUN RESET handling synchronous"). For fabrics using transport_generic_free_cmd() in the usual way the double call to transport_lun_remove_cmd() doesn't harm, as transport_lun_remove_cmd() checks for this situation and does not release lun_ref twice.

R. Silva" Date: Thu, 7 May 2020 13:53:29 -0500 Subject: i2c: mux: Replace zero-length array with flexible-array The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] sizeof(flexible-array-member) triggers a warning because flexible array members have incomplete type[1]. There are some instances of code in which the sizeof operator is being incorrectly/erroneously applied to zero-length arrays and the result is zero. Such instances may be hiding some bugs. So, this work (flexible-array member conversions) will also help to get completely rid of those sorts of issues. This issue was found with the help of Coccinelle.

The whole story started with Sergei reporting a boot crash with a kernel built with gcc-10: Kernel panic — not syncing: stack-protector: Kernel stack is corrupted in: start_secondary CPU: 1 PID: 0 Comm: swapper/1 Not tainted 5.6.0-rc5—00235—gfffb08b37df9 #139 Hardware name: Gigabyte Technology Co., Ltd. To be filled by O.E.M./H77M—D3H, BIOS F12 11/14/2013 Call Trace: dump_stack panic ? start_secondary __stack_chk_fail start_secondary secondary_startup_64 -—-[ end Kernel panic — not syncing: stack—protector: Kernel stack is corrupted in: start_secondary This happens because gcc-10 tail-call optimizes the last function call in start_secondary() - cpu_startup_entry() - and thus emits a stack canary check which fails because the canary value changes after the boot_init_stack_canary() call. To fix that, the initial attempt was to mark the one function which generates the stack canary with: __attribute__((optimize("-fno-stack-protector"))) ... start_secondary(void *unused) however, using the optimize attribute doesn't work cumulatively as the attribute does not add to but rather replaces previously supplied optimization options - roughly all -fxxx options. The key one among them being -fno-omit-frame-pointer and thus leading to not present frame pointer - frame pointer which the kernel needs. The next attempt to prevent compilers from tail-call optimizing the last function call cpu_startup_entry(), shy of carving out start_secondary() into a separate compilation unit and building it with -fno-stack-protector, was to add an empty asm(""). This current solution was short and sweet, and reportedly, is supported by both compilers but we didn't get very far this time: future (LTO?) optimization passes could potentially eliminate this, which leads us to the third attempt: having an actual memory barrier there which the compiler cannot ignore or move around etc. That should hold for a long time, but hey we said that about the other two solutions too so...

The problem described in v5.6 commit 1208f9e1d758c9 ("USB: hub: Fix the broken detection of USB3 device in SMSC hub") applies solely to the USB5534B hub [2] present on the Kingfisher Infotainment Carrier Board, manufactured by Shimafuji Electric Inc [3]. Despite that, the aforementioned commit applied the quirk to _all_ hubs carrying vendor ID 0x424 (i.e. SMSC), of which there are more [4] than initially expected. Consequently, the quirk is now enabled on platforms carrying SMSC/Microchip hub models which potentially don't exhibit the original issue. To avoid reports like [1], further limit the quirk's scope to USB5534B [2], by employing both Vendor and Product ID checks. Tested on H3ULCB + Kingfisher rev. M05.

Reference: https://www.spinics.net/lists/linux-usb/msg194331.html This bug occurs when a size variable used for a buffer is misused to access its strcpy-ed buffer. Given a buffer along with its size variable (taken from user input), from which, a new buffer is created using kstrdup(). Due to the original buffer containing 0 value in the middle, the size of the kstrdup-ed buffer becomes smaller than that of the original. So accessing the kstrdup-ed buffer with the same size variable triggers memory access violation. The fix makes sure no zero value in the buffer, by comparing the strlen() of the orignal buffer with the size variable, so that the access to the kstrdup-ed buffer is safe.

To generally fix the situation, we've recently added new helper variants bpf_probe_read_{user,kernel}() and bpf_probe_read_{user,kernel}_str(). For details on them, see 6ae08ae3dea2 ("bpf: Add probe_read_{user, kernel} and probe_read_{user,kernel}_str helpers"). Given bpf_probe_read{,str}() have been around for ~5 years by now, there are plenty of users at least on x86 still relying on them today, so we cannot remove them entirely w/o breaking the BPF tracing ecosystem. However, their use should be restricted to archs with non-overlapping address ranges where they are working in their current form.

While the helpers have been addressed through work in 6ae08ae3dea2 ("bpf: Add probe_read_{user, kernel} and probe_read_{user, kernel}_str helpers"), we need an option for bpf_trace_printk() as well to fix it. Similarly as with the helpers, force users to make an explicit choice by adding %pks and %pus specifier to bpf_trace_printk() which will then pick the corresponding strncpy_from_unsafe*() variant to perform the access under KERNEL_DS or USER_DS. The %pk* (kernel specifier) and %pu* (user specifier) can later also be extended for other objects aside strings that are probed and printed under tracing, and reused out of other facilities like bpf_seq_printf() or BTF based type printing. Existing behavior of %s for current users is still kept working for archs where it is not broken and therefore gated through CONFIG_ARCH_HAS_NON_OVERLAPPING_ADDRESS_SPACE. For archs not having this property we fall-back to pick probing under KERNEL_DS as a sensible default.

That is because SA learning on the CPU port is disabled, so the switch ignores the client's frames from the CPU port and still thinks it is at the user port. Fix it by enabling SA learning on the CPU port. To prevent the switch from learning from flooding frames from the CPU port, set skb->offload_fwd_mark to 1 for unicast and broadcast frames, and let the switch flood them instead of trapping to the CPU port. Multicast frames still need to be trapped to the CPU port for snooping, so set the SA_DIS bit of the MTK tag to 1 when transmitting those frames to disable SA learning.

We get an event log in the SHA-1 format, which doesn't have a tcg_efi_specid_event_head in the first event, and there is a final events table which doesn't match the crypto agile format. __calc_tpm2_event_size reads bad "count" and "efispecid->num_algs", and either fails, or loops long enough for the machine to be appear frozen.

Biederman" Date: Sat, 16 May 2020 16:29:20 -0500 Subject: exec: Move would_dump into flush_old_exec I goofed when I added mm->user_ns support to would_dump. I missed the fact that in the case of binfmt_loader, binfmt_em86, binfmt_misc, and binfmt_script bprm->file is reassigned. Which made the move of would_dump from setup_new_exec to __do_execve_file before exec_binprm incorrect as it can result in would_dump running on the script instead of the interpreter of the script. The net result is that the code stopped making unreadable interpreters undumpable. Which allows them to be ptraced and written to disk without special permissions. Oops. The move was necessary because the call in set_new_exec was after bprm->mm was no longer valid. To correct this mistake move the misplaced would_dump from __do_execve_file into flos_old_exec, before exec_mmap is called. I tested and confirmed that without this fix I can attach with gdb to a script with an unreadable interpreter, and with this fix I can not.

The reason was to avoid UBSAN warning. However, this change has caused performance degrade and in GCC-8, fno-strict-overflow is now mapped to -fwrapv -fwrapv-pointer and signed integer overflow is now undefined by default at all optimization levels[1]. Moreover, it was a bug in UBSAN vs -fwrapv /-fno-strict-overflow, so Let's revert it safely.

If that happens, the machine cannot be woken up from suspend-to-idle by the power button or lid status change and it needs to be woken up in some other way (eg. by a key press).

The module removal entails DSP power down, disabling of IRQs and more. Therefore it is highly recommended to inform the DSP about this upcoming event. Due to hardware limitations on some Intel platforms it is necessary to power gate all LPSRAM banks that were enabled prior to controller reset. Otherwise, an attempt to write LPSRAM control registers may have no effect.

Whilst this might speed up the application a bit, it's a problem if there's a network failure and the operation has to be reissued. If this happens, an oops occurs because afs_readpages_page_done() clears the pointer to each page it unlocks and when a retry happens, the pointers to the pages it wants to fill are now NULL (and the pages have been unlocked anyway). Instead, wait till the operation completes successfully and only then release all the pages after clearing any terminal gap (the server can give us less data than we requested as we're allowed to ask for more than is available).

In this case we want to expose perfmon information for both cores. The driver has one array which contains all possible perfmon domains with some meta data - doms_meta. Here we can see that for the GC860 two elements of that array are relevant: doms_3d: is at index 0 in the doms_meta array with 8 perfmon domains doms_2d: is at index 1 in the doms_meta array with 1 perfmon domain The userspace driver wants to get a list of all perfmon domains and their perfmon signals. This is done by iterating over all domains and their signals. If the userspace driver wants to access the domain with id 8 the kernel driver fails and returns invalid data from doms_3d with and invalid offset. This results in: Unable to handle kernel paging request at virtual address 00000000 On such a device it is not possible to use the userspace driver at all. The fix for this off-by-one error is quite simple.

This is needed in kdump kernels where the new domain must not be attached to a device before the device driver takes it over. When the AMD IOMMU driver got converted to use the dma-iommu implementation, the deferred attaching got lost. The code in dma-iommu.c has support for deferred attaching, but it calls into iommu_attach_device() to actually do it. But iommu_attach_device() will check if the device should be deferred in it code-path and do nothing, breaking deferred attachment. Move the is_deferred_attach() check out of the attach_device path and into iommu_group_add_device() to make deferred attaching work from the dma-iommu code.

This causes multiple issues: - The device link is lost forever from driver core if the caller didn't keep track of it (caller typically isn't expected to). This is a memory leak. - The device link is also never visible to any other code path after device_link_add() returns. If we fix the "device link" list handling, that exposes a bunch of issues. 1. The device link "status" state management code rightfully doesn't handle the case where a DL_FLAG_MANAGED device link exists between a supplier and consumer, but the consumer manages to probe successfully before the supplier. The addition of DL_FLAG_SYNC_STATE_ONLY links break this assumption. This causes device_links_driver_bound() to throw a warning when this happens. Since DL_FLAG_SYNC_STATE_ONLY device links are mainly used for creating proxy device links for child device dependencies and aren't useful once the consumer device probes successfully, this patch just deletes DL_FLAG_SYNC_STATE_ONLY device links once its consumer device probes. This way, we avoid the warning, free up some memory and avoid complicating the device links "status" state management code. 2. Creating a DL_FLAG_STATELESS device link between two devices that already have a DL_FLAG_SYNC_STATE_ONLY device link will result in the DL_FLAG_STATELESS flag not getting set correctly. This patch also fixes this. Lastly, this patch also fixes minor whitespace issues.

There is a case where the first for_each_sched_entity loop exits due to on_rq, having incompletely updated the list. In this case the second for_each_sched_entity loop can further modify se. The later code to fix up the list management fails to do what is needed because se does not point to the sched_entity which broke out of the first loop. The list is not fixed up because the throttled parent was already added back to the list by a task enqueue in a parallel child hierarchy. Address this by calling list_add_leaf_cfs_rq if there are throttled parents while doing the second for_each_sched_entity loop.

Given the number of sites where %p is used (over 10000) and the fact that NULL pointers aren't uncommon, it probably wouldn't take long for an attacker to find the hash that corresponds to 0. Although harder, the same goes for most common error values, such as -1, -2, -11, -14, etc. The NULL part actually fixes a regression: NULL pointers weren't obfuscated until commit 3e5903eb9cff ("vsprintf: Prevent crash when dereferencing invalid pointers") which went into 5.2. I'm tacking the IS_ERR() part on here because error pointers won't leak kernel addresses and printing them as pointers shouldn't be any different from e.g. %d with PTR_ERR_OR_ZERO(). Obfuscating them just makes debugging based on existing pr_debug and friends excruciating. Note that the "always print 0's for %pK when kptr_restrict == 2" behaviour which goes way back is left as is.

(This is since ext4_extent's ee_block is __le32). This means that EXT4_MAX_LOGICAL_BLOCK should be 0xfffffffe (starting from 0 logical offset). This patch fixes this. The issue was seen when ext4 moved to iomap_fiemap API and when overlayfs was mounted on top of ext4. Since overlayfs was missing filemap_check_ranges(), so it could pass a arbitrary huge length which lead to overflow of map.m_len logic. This patch fixes that.

That makes the driver useful on Device Tree based systems, with audio-graph-card or simple-card. The aforementioned card drivers control the master clock themselves and don't call the set_dai_sysclk() or set_dai_pll(), thus the respective handlers don't serve any purpose anymore. Instead, they return early and the hw_params() handler sets the appropriate bitclk itself. The register range is split into two -- for the RX block and for the TX block. On a MMP2 there are two pairs of them; the first one has the clock controller in the middle, while the second just has a hole: 0xd42a0c00 - 0xd42a0c30 RX1 0xd42a0c30 - 0xd42a0c40 Clocks 0xd42a0c80 - 0xd42a0cb0 TX1 0xd42a0d00 - 0xd42a0d30 RX2 0xd42a0d80 - 0xd42a0cb0 TX2 For this reason, mmp_sspa_write_reg() and mmp_sspa_read_reg() are replaced with direct calls to I/O routines. Tested on a MMP2-based OLPC XO-1.75 laptop with rt5631 coded, mmp_tdma DMA engine and MMP2 clock controller glued together with audio-graph-card.

The tb->fast* caches the address of a sk which has successfully been binded with SO_REUSEPORT ON. The idea is to avoid the expensive conflict search in inet_csk_bind_conflict(). There is an issue with wildcard matching where sk_reuseport_match() should have returned false but it is currently returning true. It ends up hiding bind conflict. For example, bind("[::1]:443"); /* without SO_REUSEPORT. Succeed. */ bind("[::2]:443"); /* with SO_REUSEPORT. Succeed. */ bind("[::]:443"); /* with SO_REUSEPORT. Still Succeed where it shouldn't */ The last bind("[::]:443") with SO_REUSEPORT on should have failed because it should have a conflict with the very first bind("[::1]:443") which has SO_REUSEPORT off. However, the address "[::2]" is cached in tb->fast* in the second bind. In the last bind, the sk_reuseport_match() returns true because the binding sk's wildcard addr "[::]" matches with the "[::2]" cached in tb->fast*. The correct bind conflict is reported by removing the second bind such that tb->fast* cache is not involved and forces the bind("[::]:443") to go through the inet_csk_bind_conflict(): bind("[::1]:443"); /* without SO_REUSEPORT. Succeed. */ bind("[::]:443"); /* with SO_REUSEPORT. -EADDRINUSE */ The expected behavior for sk_reuseport_match() is, it should only allow the "cached" tb->fast* address to be used as a wildcard match but not the address of the binding sk. To do that, the current "bool match_wildcard" arg is split into "bool match_sk1_wildcard" and "bool match_sk2_wildcard". This change only affects the sk_reuseport_match() which is only used by inet_csk (e.g. TCP). The other use cases are calling inet_rcv_saddr_equal() and this patch makes it pass the same "match_wildcard" arg twice to the "ipv[46]_rcv_saddr_equal(..., match_wildcard, match_wildcard)".

This of course leads to the BUG halt in add_timer getting called. Fix seems pretty straightforward, just check before the timer is added if its already been started. If it has mod the timer instead to min(current expiration, new expiration) Its been tested but not confirmed to fix the problem, as the issue has only occured in production environments where test kernels are enjoined from being installed.

Therefore, set_huge_pte_at() does a conversion from a normal pte to the corresponding large pmd/pud. So, when converting an empty pte, this should result in an empty pmd/pud, which would return true for pmd/pud_none(). However, after conversion we also mark the pmd/pud as large, and therefore present. For empty ptes, this will result in an empty pmd/pud that is also marked as large, and pmd/pud_none() would not return true. There is currently no issue with this behaviour, as set_huge_pte_at() does not seem to be called for empty ptes. It would be valid though, so let's fix this by not marking empty ptes as large in set_huge_pte_at(). This was found by testing a patch from from Anshuman Khandual, which is currently discussed on LKML ("mm/debug: Add more arch page table helper tests").

This was found with a zfcpdump kernel config, where CONFIG_MODULES=n and CONFIG_VFIO=n. In that case, symbol_get() is used on undefined __weak symbols in virt/kvm/vfio.c, which results in the generation of R_390_JMP_SLOT relocation types.

However, at this point, it reflects which method was used to re-start the syscall at the entry stop, rather than the method that was used to reach it. Fix that by recording the original flag before performing the ptrace stop, bringing the behavior in line with documentation and x86/powerpc.

This reverts commit 697ece78f8f749aeea40f2711389901f0974017a. The implementation of SWAP on powerpc requires page protection bits to not be one of the least significant PTE bits. Until the SWAP implementation is changed and this requirement voids, we have to keep at least _PAGE_RW outside of the 3 last bits. For now, revert to previous PTE bits order.

Sometimes it contains the serial number of the last DATA packet received, sometimes the sequence number of the last DATA packet received and sometimes the highest sequence number so far received. AF_RXRPC is using this to weed out ACKs that are out of date (it's possible for ACK packets to get reordered on the wire), but this does not work with OpenAFS which will just stick the sequence number of the last packet seen into previousPacket. The issue being seen is that big AFS FS.StoreData RPC (eg. of ~256MiB) are timing out when partly sent. A trace was captured, with an additional tracepoint to show ACKs being discarded in rxrpc_input_ack().

We then end up in a continuous cycle of retransmit/discard. kafs fails to update its window because it's discarding the ACKs and can't transmit an extra packet that would clear the issue because the window is full. OpenAFS doesn't change the previousPacket value in the ACKs because no new DATA packets are received with a different previousPacket number. Fix this by altering the discard check to only discard an ACK based on previousPacket if there was no advance in the firstPacket. This allows us to transmit a new packet which will cause previousPacket to advance in the next ACK. The check, however, needs to allow for the possibility that previousPacket may actually have had the serial number placed in it instead - in which case it will go outside the window and we should ignore it.

The cursor update can be delayed indefinitely if the cursor update repeatedly happens right around VUPDATE. The underflow issue can happen if we do a viewport update on a pipe on the same frame where a cursor update happens around VUPDATE - the old cursor registers are retained which can be in an invalid position. This can cause a pipe hang and indefinite underflow. [How] The complex, ideal solution to the problem would be a software triple buffering mechanism from the DM layer to program only one cursor update per frame just before VUPDATE. The simple workaround until we have that infrastructure in place is this change - bring back the delay until VUPDATE before locking, but with some corrections to the calculations. This didn't work for all timings before because the calculation for VUPDATE was wrong - it was using the offset from VSTARTUP instead and didn't correctly handle the case where VUPDATE could be in the back porch. Add a new hardware sequencer function to use the existing helper to calculate the real VUPDATE start and VUPDATE end - VUPDATE can last multiple lines after all. Change the udelay to incorporate the width of VUPDATE as well.

So copy that part of the state into a temporary like we do with the rest of the handshake state variables. Then we can release the lock, operate on the temporary, and zero it out at the end of the function. In performance tests, the impact of this was entirely unnoticable, probably because those bytes are coming from the same cacheline as other things that are being copied out in the same manner.

But, for encapsulation, it's wrong to clear skb->hash, since it's used by fq_codel and flow dissection in general. Without it, classification does not proceed as usual. This change might make it easier to estimate the number of innerflows by examining clustering of out of order packets, but this shouldn't open up anything that can't already be inferred otherwise (e.g. syn packet size inference), and fq_codel can be disabled anyway. Furthermore, it might be the case that the hash isn't used or queried at all until after wireguard transmits the encrypted UDP packet, which means skb->hash might still be zero at this point, and thus no hash taken over the inner packet data. In order to address this situation, we force a calculation of skb->hash before encrypting packet data. Of course this means that fq_codel might transmit packets slightly more out of order than usual. Toke did some testing on beefy machines with high quantities of parallel flows and found that increasing the reply-attack counter to 8192 takes care of the most pathological cases pretty well.

Donenfeld" Date: Tue, 19 May 2020 22:49:30 -0600 Subject: wireguard: noise: separate receive counter from send counter In "wireguard: queueing: preserve flow hash across packet scrubbing", we were required to slightly increase the size of the receive replay counter to something still fairly small, but an increase nonetheless. It turns out that we can recoup some of the additional memory overhead by splitting up the prior union type into two distinct types. Before, we used the same "noise_counter" union for both sending and receiving, with sending just using a simple atomic64_t, while receiving used the full replay counter checker. This meant that most of the memory being allocated for the sending counter was being wasted. Since the old "noise_counter" type increased in size in the prior commit, now is a good time to split up that union type into a distinct "noise_replay_ counter" for receiving and a boring atomic64_t for sending, each using neither more nor less memory than required. Also, since sometimes the replay counter is accessed without necessitating additional accesses to the bitmap, we can reduce cache misses by hoisting the always-necessary lock above the bitmap in the struct layout. We also change a "noise_replay_counter" stack allocation to kmalloc in a -DDEBUG selftest so that KASAN doesn't trigger a stack frame warning. All and all, removing a bit of abstraction in this commit makes the code simpler and smaller, in addition to the motivating memory usage recuperation. For example, passing around raw "noise_symmetric_key" structs is something that really only makes sense within noise.c, in the one place where the sending and receiving keys can safely be thought of as the same type of object; subsequent to that, it's important that we uniformly access these through keypair->{sending,receiving}, where their distinct roles are always made explicit. So this patch allows us to draw that distinction clearly as well. Fixes: e7096c131e51 ("net: WireGuard secure network tunnel") Signed-off-by: Jason A. Donenfeld Signed-off-by: David S.

To fix that, adding function __kboject_del() that does everything that kobject_del() does except release the parent reference. kobject_cleanup() then calls __kobject_del() instead of kobject_del(), and separately decrements the reference count of the parent kobject after kobj->release() has been called.

Various paths in our ftrace, kprobes and other patching code need to be hardened against patching failures, otherwise we can end up running with partially/incorrectly patched ftrace paths, kprobes or jump labels, which can then cause strange crashes. Although fixes for those are in development, they're not -rc material. There also seem to be problems with the underlying strict RWX logic, which needs further debugging.

In effect, we're in the same situation as if userspace had requested a PF_UNSPEC dump. For RTM_GETROUTE, that handler is rtnl_dump_all, which calls all the registered RTM_GETROUTE handlers. The requested table id may or may not exist for all of those families. commit ae677bbb4441 ("net: Don't return invalid table id error when dumping all families") fixed the problem when userspace explicitly requests a PF_UNSPEC dump, but missed the fallback case. For example, when we pass ipv6.disable=1 to a kernel with CONFIG_IP_MROUTE=y and CONFIG_IP_MROUTE_MULTIPLE_TABLES=y, the (PF_INET6, RTM_GETROUTE) handler isn't registered, so we end up in rtnl_dump_all, and listing IPv6 routes will unexpectedly print: # ip -6 r Error: ipv4: MR table does not exist. Dump terminated commit ae677bbb4441 introduced the dump_all_families variable, which gets set when userspace requests a PF_UNSPEC dump. However, we can't simply set the family to PF_UNSPEC in rtnetlink_rcv_msg in the fallback case to get dump_all_families == true, because some messages types (for example RTM_GETRULE and RTM_GETNEIGH) only register the PF_UNSPEC handler and use the family to filter in the kernel what is dumped to userspace. We would then export more entries, that userspace would have to filter. iproute does that, but other programs may not. Instead, this patch removes dump_all_families and updates the RTM_GETROUTE handlers to check if the family that is being dumped is their own. When it's not, which covers both the intentional PF_UNSPEC dumps (as dump_all_families did) and the fallback case, ignore the missing table id error.

In parallel, it unwinds the stack with unwind_next_frame(). If the stack address matches the pointer returned by unwind_get_return_address_ptr() for the current frame, the text address is printed normally without a question mark. Otherwise it's considered a breadcrumb (potentially from a previous call path) and it's printed with a question mark to indicate that the address is unreliable and typically can be ignored. Since the following commit: f1d9a2abff66 ("x86/unwind/orc: Don't skip the first frame for inactive tasks") ... for inactive tasks, show_trace_log_lvl() prints *only* unreliable addresses (prepended with '?'). That happens because, for the first frame of an inactive task, unwind_get_return_address_ptr() returns the wrong return address pointer: one word *below* the task stack pointer. show_trace_log_lvl() starts scanning at the stack pointer itself, so it never finds the first 'reliable' address, causing only guesses to being printed. The first frame of an inactive task isn't a normal stack frame. It's actually just an instance of 'struct inactive_task_frame' which is left behind by __switch_to_asm(). Now that this inactive frame is actually exposed to callers, fix unwind_get_return_address_ptr() to interpret it properly.

Meaning that after it computes the final physical start address it saves the address for no reason in the static tables. This doesn't affect the first driver probing after reboot, but it breaks consecutive driver reloads (i.e. driver unbind & bind) because the initialization tables no longer have the correct initial values. So the next probe() will map the device registers to wrong physical addresses, causing ARM SError async exceptions. This patch fixes all of the above.

The analysis is below: I've been investigating this afternoon, and what I've found, comparing a kernel without 895586d5dc32 and with 895586d5dc32 applied is: - The table programmed into the hardware via mvpp22_rss_fill_table() appears to be identical with or without the commit. - When rxhash is enabled on eth2, mvpp2_rss_port_c2_enable() reports that c2.attr[0] and c2.attr[2] are written back containing: - with 895586d5dc32, failing: 00200000 40000000 - without 895586d5dc32, working: 04000000 40000000 - When disabling rxhash, c2.attr[0] and c2.attr[2] are written back as: 04000000 00000000 The second value represents the MVPP22_CLS_C2_ATTR2_RSS_EN bit, the first value is the queue number, which comprises two fields. The high 5 bits are 24:29 and the low three are 21:23 inclusive. This comes from: c2.attr[0] = MVPP22_CLS_C2_ATTR0_QHIGH(qh) | MVPP22_CLS_C2_ATTR0_QLOW(ql); So, the working case gives eth2 a queue id of 4.0, or 32 as per port->first_rxq, and the non-working case a queue id of 0.1, or 1. The allocation of queue IDs seems to be in mvpp2_port_probe(): if (priv->hw_version == MVPP21) port->first_rxq = port->id * port->nrxqs; else port->first_rxq = port->id * priv->max_port_rxqs; Where: if (priv->hw_version == MVPP21) priv->max_port_rxqs = 8; else priv->max_port_rxqs = 32; Making the port 0 (eth0 / eth1) have port->first_rxq = 0, and port 1 (eth2) be 32. It seems the idea is that the first 32 queues belong to port 0, the second 32 queues belong to port 1, etc. mvpp2_rss_port_c2_enable() gets the queue number from it's parameter, 'ctx', which comes from mvpp22_rss_ctx(port, 0). This returns port->rss_ctx[0]. mvpp22_rss_context_create() is responsible for allocating that, which it does by looking for an unallocated priv->rss_tables[] pointer. This table is shared amongst all ports on the CP silicon. When we write the tables in mvpp22_rss_fill_table(), the RSS table entry is defined by: u32 sel = MVPP22_RSS_INDEX_TABLE(rss_ctx) | MVPP22_RSS_INDEX_TABLE_ENTRY(i); where rss_ctx is the context ID (queue number) and i is the index in the table. If we look at what is written: - The first table to be written has "sel" values of 00000000..0000001f, containing values 0..3. This appears to be for eth1. This is table 0, RX queue number 0. - The second table has "sel" values of 00000100..0000011f, and appears to be for eth2. These contain values 0x20..0x23. This is table 1, RX queue number 0. - The third table has "sel" values of 00000200..0000021f, and appears to be for eth3. These contain values 0x40..0x43. This is table 2, RX queue number 0. How do queue numbers translate to the RSS table? There is another table - the RXQ2RSS table, indexed by the MVPP22_RSS_INDEX_QUEUE field of MVPP22_RSS_INDEX and accessed through the MVPP22_RXQ2RSS_TABLE register. Before 895586d5dc32, it was: mvpp2_write(priv, MVPP22_RSS_INDEX, MVPP22_RSS_INDEX_QUEUE(port->first_rxq)); mvpp2_write(priv, MVPP22_RXQ2RSS_TABLE, MVPP22_RSS_TABLE_POINTER(port->id)); and after: mvpp2_write(priv, MVPP22_RSS_INDEX, MVPP22_RSS_INDEX_QUEUE(ctx)); mvpp2_write(priv, MVPP22_RXQ2RSS_TABLE, MVPP22_RSS_TABLE_POINTER(ctx)); Before the commit, for eth2, that would've contained '32' for the index and '1' for the table pointer - mapping queue 32 to table 1. Remember that this is queue-high.queue-low of 4.0. After the commit, we appear to map queue 1 to table 1. That again looks fine on the face of it. Section 9.3.1 of the A8040 manual seems indicate the reason that the queue number is separated. queue-low seems to always come from the classifier, whereas queue-high can be from the ingress physical port number or the classifier depending on the MVPP2_CLS_SWFWD_PCTRL_REG. We set the port bit in MVPP2_CLS_SWFWD_PCTRL_REG, meaning that queue-high comes from the MVPP2_CLS_SWFWD_P2HQ_REG() register... and this seems to be where our bug comes from. mvpp2_cls_oversize_rxq_set() sets this up as: mvpp2_write(port->priv, MVPP2_CLS_SWFWD_P2HQ_REG(port->id), (port->first_rxq >> MVPP2_CLS_OVERSIZE_RXQ_LOW_BITS)); val = mvpp2_read(port->priv, MVPP2_CLS_SWFWD_PCTRL_REG); val |= MVPP2_CLS_SWFWD_PCTRL_MASK(port->id); mvpp2_write(port->priv, MVPP2_CLS_SWFWD_PCTRL_REG, val); Setting the MVPP2_CLS_SWFWD_PCTRL_MASK bit means that the queue-high for eth2 is _always_ 4, so only queues 32 through 39 inclusive are available to eth2. Yet, we're trying to tell the classifier to set queue-high, which will be ignored, to zero. Hence, the queue-high field (MVPP22_CLS_C2_ATTR0_QHIGH()) from the classifier will be ignored. This means we end up directing traffic from eth2 not to queue 1, but to queue 33, and then we tell it to look up queue 33 in the RSS table. However, RSS table has not been programmed for queue 33, and so it ends up (presumably) dropping the packets. It seems that mvpp22_rss_context_create() doesn't take account of the fact that the upper 5 bits of the queue ID can't actually be changed due to the settings in mvpp2_cls_oversize_rxq_set(), _or_ it seems that mvpp2_cls_oversize_rxq_set() has been missed in this commit. Either way, these two functions mutually disagree with what queue number should be used. Looking deeper into what mvpp2_cls_oversize_rxq_set() and the MTU validation is doing, it seems that MVPP2_CLS_SWFWD_P2HQ_REG() is used for over-sized packets attempting to egress through this port. With the classifier having had RSS enabled and directing eth2 traffic to queue 1, we may still have packets appearing on queue 32 for this port. However, the only way we may end up with over-sized packets attempting to egress through eth2 - is if the A8040 forwards frames between its ports. From what I can see, we don't support that feature, and the kernel restricts the egress packet size to the MTU. In any case, if we were to attempt to transmit an oversized packet, we have no support in the kernel to deal with that appearing in the port's receive queue. So, this patch attempts to solve the issue by clearing the MVPP2_CLS_SWFWD_PCTRL_MASK() bit, allowing MVPP22_CLS_C2_ATTR0_QHIGH() from the classifier to define the queue-high field of the queue number. My testing seems to confirm my findings above - clearing this bit means that if I enable rxhash on eth2, the interface can then pass traffic, as we are now directing traffic to RX queue 1 rather than queue 33. Traffic still seems to work with rxhash off as well.

However, the rationale stated in that commit applies also when in SHUTDOWN-SENT state - we don't want to move an association to ESTABLISHED state when the socket has been closed, because that results in an association that is unreachable from user space. The problem scenario: 1. Client crashes and/or restarts. 2. Server (using one-to-one socket) calls close(). SHUTDOWN is lost. 3. Client reconnects using the same addresses and ports. 4. Server's association is restarted. The association and the socket move to ESTABLISHED state, even though the server process has closed its descriptor. Also, after step 4 when the server process exits, some resources are leaked in an attempt to release the underlying inet sock structure in ESTABLISHED state: IPv4: Attempt to release TCP socket in state 1 00000000377288c7 Fix by acting the same way as in SHUTDOWN-PENDING state.

The previous implementation called netif_device_detach(). This however causes the initial activation of the netdevice to fail precisely because it's detached. For details, see [1]. A possible workaround was the revert of commit net: linkwatch: add check for netdevice being present to linkwatch_do_dev However, the check introduced in the above commit is correct and shall be kept. The netif_device_detach() is thus replaced with netif_tx_stop_all_queues() that prevents any tranmission. This allows to perform mac config change required by the link change, without detaching the corresponding netdevice and thus not preventing its initial activation.

Add SW mechanism that once the CREATE_EQ command is about to be executed, all other commands will return error without being sent to the FW. Allow sending other commands only after successfully changing the driver's internal command mode metadata. We can safely return error to all other commands while creating the command EQ, as all other commands might be sent from the user/application during driver load. Application can rerun them later after driver's load was finished.

One note here is that soc_cleanup_card_resources() will be called as (A) formal cleanup or as (B) error handling, thus, it needs to distinguish these. In (A) case, card will have "instantiated" flag if all probe callback functions were called without error. Thus, snd_soc_unbind_card() is using it to judging card was probed.
