Since commit 10a68cdf10 (nfsd: fix performance-limiting session
calculation) (Linux 5.1-rc1 and 4.19.31), shares from NFS servers with
1 TB of memory cannot be mounted anymore. The mount just hangs on the
client.
The gist of commit 10a68cdf10 is the change below.
-avail = clamp_t(int, avail, slotsize, avail/3);
+avail = clamp_t(int, avail, slotsize, total_avail/3);
Here are the macros.
#define min_t(type, x, y) __careful_cmp((type)(x), (type)(y), <)
#define clamp_t(type, val, lo, hi) min_t(type, max_t(type, val, lo), hi)
`total_avail` is 8,434,659,328 on the 1 TB machine. `clamp_t()` casts
the values to `int`, which for 32-bit integers can only hold values
−2,147,483,648 (−2^31) through 2,147,483,647 (2^31 − 1).
`avail` (in the function signature) is just 65536, so that no overflow
was happening. Before the commit the assignment would result in 21845,
and `num = 4`.
When using `total_avail`, it is causing the assignment to be
18446744072226137429 (printed as %lu), and `num` is then 4164608182.
My next guess is, that `nfsd_drc_mem_used` is then exceeded, and the
server thinks there is no memory available any more for this client.
Updating the arguments of `clamp_t()` and `min_t()` to `unsigned long`
fixes the issue.
Now, `avail = 65536` (before commit 10a68cdf10 `avail = 21845`), but
`num = 4` remains the same.

Michal Suchanek reported [1] that running the pcrypt_aead01 test from
LTP [2] in a loop and holding Ctrl-C causes a NULL dereference of
alg->cra_users.next in crypto_remove_spawns(), via crypto_del_alg().
The test repeatedly uses CRYPTO_MSG_NEWALG and CRYPTO_MSG_DELALG.
The crash occurs when the instance that CRYPTO_MSG_DELALG is trying to
unregister isn't a real registered algorithm, but rather is a "test
larval", which is a special "algorithm" added to the algorithms list
while the real algorithm is still being tested. Larvals don't have
initialized cra_users, so that causes the crash. Normally pcrypt_aead01
doesn't trigger this because CRYPTO_MSG_NEWALG waits for the algorithm
to be tested; however, CRYPTO_MSG_NEWALG returns early when interrupted.
Everything else in the "crypto user configuration" API has this same bug
too, i.e. it inappropriately allows operating on larval algorithms
(though it doesn't look like the other cases can cause a crash).
Fix this by making crypto_alg_match() exclude larval algorithms.

WRITE SAME corrupts data on the block device behind iblock if the command
is emulated. The emulation code issues (M - 1) * N times more bios than
requested, where M is the number of 512 blocks per real block size and N is
the NUMBER OF LOGICAL BLOCKS specified in WRITE SAME command. So, for a
device with 4k blocks, 7 * N more LBAs gets written after the requested
range.
The issue happens because the number of 512 byte sectors to be written is
decreased one by one while the real bios are typically from 1 to 8 512 byte
sectors per bio.

I ran into an intriguing bug caused by
commit ""spi: gpio: Don't request CS GPIO in DT use-case"
affecting all SPI GPIO devices with an active high
chip select line.
The commit switches the CS gpio handling over to the GPIO
core, which will parse and handle "cs-gpios" from the OF
node without even calling down to the driver to get the
job done.
However the GPIO core handles the standard bindings in
Documentation/devicetree/bindings/spi/spi-controller.yaml
that specifies that active high CS needs to be specified
using "spi-cs-high" in the DT node.
The code in drivers/spi/spi-gpio.c never respected this
and never tried to inspect subnodes to see if they contained
"spi-cs-high" like the gpiolib OF quirks does. Instead the
only way to get an active high CS was to tag it in the
device tree using the flags cell such as
cs-gpios = <&gpio 4 GPIO_ACTIVE_HIGH>;
This alters the quirks to not inspect the subnodes of SPI
masters on "spi-gpio" for the standard attribute "spi-cs-high",
making old device trees work as expected.
This semantic is a bit ambigous, but just allowing the
flags on the GPIO descriptor to modify polarity is what
the kernel at large mostly uses so let's encourage that.

LINE6 drivers allocate the buffers based on the value returned from
usb_maxpacket() calls. The manipulated device may return zero for
this, and this results in the kmalloc() with zero size (and it may
succeed) while the other part of the driver code writes the packet
data with the fixed size -- which eventually overwrites.
This patch adds a simple sanity check for the invalid buffer size for
avoiding that problem.

Thomas reported that:
| Background:
|
| In preparation of supporting IPI shorthands I changed the CPU offline
| code to software disable the local APIC instead of just masking it.
| That's done by clearing the APIC_SPIV_APIC_ENABLED bit in the APIC_SPIV
| register.
|
| Failure:
|
| When the CPU comes back online the startup code triggers occasionally
| the warning in apic_pending_intr_clear(). That complains that the IRRs
| are not empty.
|
| The offending vector is the local APIC timer vector who's IRR bit is set
| and stays set.
|
| It took me quite some time to reproduce the issue locally, but now I can
| see what happens.
|
| It requires apicv_enabled=0, i.e. full apic emulation. With apicv_enabled=1
| (and hardware support) it behaves correctly.
|
| Here is the series of events:
|
| Guest CPU
|
| goes down
|
| native_cpu_disable()
|
| apic_soft_disable();
|
| play_dead()
|
| ....
|
| startup()
|
| if (apic_enabled())
| apic_pending_intr_clear() <- Not taken
|
| enable APIC
|
| apic_pending_intr_clear() <- Triggers warning because IRR is stale
|
| When this happens then the deadline timer or the regular APIC timer -
| happens with both, has fired shortly before the APIC is disabled, but the
| interrupt was not serviced because the guest CPU was in an interrupt
| disabled region at that point.
|
| The state of the timer vector ISR/IRR bits:
|
| ISR IRR
| before apic_soft_disable() 0 1
| after apic_soft_disable() 0 1
|
| On startup 0 1
|
| Now one would assume that the IRR is cleared after the INIT reset, but this
| happens only on CPU0.
|
| Why?
|
| Because our CPU0 hotplug is just for testing to make sure nothing breaks
| and goes through an NMI wakeup vehicle because INIT would send it through
| the boots-trap code which is not really working if that CPU was not
| physically unplugged.
|
| Now looking at a real world APIC the situation in that case is:
|
| ISR IRR
| before apic_soft_disable() 0 1
| after apic_soft_disable() 0 1
|
| On startup 0 0
|
| Why?
|
| Once the dying CPU reenables interrupts the pending interrupt gets
| delivered as a spurious interupt and then the state is clear.
|
| While that CPU0 hotplug test case is surely an esoteric issue, the APIC
| emulation is still wrong, Even if the play_dead() code would not enable
| interrupts then the pending IRR bit would turn into an ISR .. interrupt
| when the APIC is reenabled on startup.
From SDM 10.4.7.2 Local APIC State After It Has Been Software Disabled
* Pending interrupts in the IRR and ISR registers are held and require
masking or handling by the CPU.
In Thomas's testing, hardware cpu will not respect soft disable LAPIC
when IRR has already been set or APICv posted-interrupt is in flight,
so we can skip soft disable APIC checking when clearing IRR and set ISR,
continue to respect soft disable APIC when attempting to set IRR.

Currently KVM_STATE_NESTED_EVMCS is used to signal that eVMCS
capability is enabled on vCPU.
As indicated by vmx->nested.enlightened_vmcs_enabled.
This is quite bizarre as userspace VMM should make sure to expose
same vCPU with same CPUID values in both source and destination.
In case vCPU is exposed with eVMCS support on CPUID, it is also
expected to enable KVM_CAP_HYPERV_ENLIGHTENED_VMCS capability.
Therefore, KVM_STATE_NESTED_EVMCS is redundant.
KVM_STATE_NESTED_EVMCS is currently used on restore path
(vmx_set_nested_state()) only to enable eVMCS capability in KVM
and to signal need_vmcs12_sync such that on next VMEntry to guest
nested_sync_from_vmcs12() will be called to sync vmcs12 content
into eVMCS in guest memory.
However, because restore nested-state is rare enough, we could
have just modified vmx_set_nested_state() to always signal
need_vmcs12_sync.
From all the above, it seems that we could have just removed
the usage of KVM_STATE_NESTED_EVMCS. However, in order to preserve
backwards migration compatibility, we cannot do that.
(vmx_get_nested_state() needs to signal flag when migrating from
new kernel to old kernel).
Returning KVM_STATE_NESTED_EVMCS when just vCPU have eVMCS enabled
have a bad side-effect of userspace VMM having to send nested-state
from source to destination as part of migration stream. Even if
guest have never used eVMCS as it doesn't even run a nested
hypervisor workload. This requires destination userspace VMM and
KVM to support setting nested-state. Which make it more difficult
to migrate from new host to older host.
To avoid this, change KVM_STATE_NESTED_EVMCS to signal eVMCS is
not only enabled but also active. i.e. Guest have made some
eVMCS active via an enlightened VMEntry. i.e. vmcs12 is copied
from eVMCS and therefore should be restored into eVMCS resident
in memory (by copy_vmcs12_to_enlightened()).

As comment in code specifies, SMM temporarily disables VMX so we cannot
be in guest mode, nor can VMLAUNCH/VMRESUME be pending.
However, code currently assumes that these are the only flags that can be
set on kvm_state->flags. This is not true as KVM_STATE_NESTED_EVMCS
can also be set on this field to signal that eVMCS should be enabled.
Therefore, fix code to check for guest-mode and pending VMLAUNCH/VMRESUME
explicitly.

Despite what I think the prm recommends, commit f2253bd9859b
("drm/i915/ringbuffer: EMIT_INVALIDATE after switch context") turned out
to be a huge mistake when enabling Ironlake contexts as the GPU would
hang on either a MI_FLUSH or PIPE_CONTROL immediately following the
MI_SET_CONTEXT of an active mesa context (more vanilla contexts, e.g.
simple rendercopies with igt, do not suffer).
Ville found the following clue,
"[DevCTG+]: For the invalidate operation of the pipe control, the
following pointers are affected. The
invalidate operation affects the restore of these packets. If the pipe
control invalidate operation is completed
before the context save, the indirect pointers will not be restored from
memory.
1. Pipeline State Pointer
2. Media State Pointer
3. Constant Buffer Packet"
which suggests by us emitting the INVALIDATE prior to the MI_SET_CONTEXT,
we prevent the context-restore from chasing the dangling pointers within
the image, and explains why this likely prevents the GPU hang.

The widget_mutex was introduced to serialize callers to
hda_widget_sysfs_{re}init. However, its protection of the sysfs widget array
is incomplete. For example, it is acquired around the call to
hda_widget_sysfs_reinit(), which actually creates the new array, but isn't
still acquired when codec->num_nodes and codec->start_nid is updated. So
the lock ensures one thread sets up the new array at a time, but doesn't
ensure which thread's value will end up in codec->num_nodes. If a larger
num_nodes wins but a smaller array was set up, the next call to
refresh_widgets() will touch free memory as it iterates over codec->num_nodes
that aren't there.
The widget_lock really protects both the tree as well as codec->num_nodes,
start_nid, and end_nid, so make sure it's held across that update. It should
also be held during snd_hdac_get_sub_nodes(), so that a very old read from that
function doesn't end up clobbering a later update.

In IEC 61883-6, 8 MIDI data streams are multiplexed into single
MIDI conformant data channel. The index of stream is calculated by
modulo 8 of the value of data block counter.
In fireworks, the value of data block counter in CIP header has a quirk
with firmware version v5.0.0, v5.7.3 and v5.8.0. This brings ALSA
IEC 61883-1/6 packet streaming engine to miss detection of MIDI
messages.
This commit fixes the miss detection to modify the value of data block
counter for the modulo calculation.
For maintainers, this bug exists since a commit 18f5ed365d3f ("ALSA:
fireworks/firewire-lib: add support for recent firmware quirk") in Linux
kernel v4.2. There're many changes since the commit. This fix can be
backported to Linux kernel v4.4 or later. I tagged a base commit to the
backport for your convenience.
Besides, my work for Linux kernel v5.3 brings heavy code refactoring and
some structure members are renamed in 'sound/firewire/amdtp-stream.h'.
The content of this patch brings conflict when merging -rc tree with
this patch and the latest tree. I request maintainers to solve the
conflict to replace 'tx_first_dbc' with 'ctx_data.tx.first_dbc'.

sys_move_mount() crashes by dereferencing the pointer MNT_NS_INTERNAL,
a.k.a. ERR_PTR(-EINVAL), if the old mount is specified by fd for a
kernel object with an internal mount, such as a pipe or memfd.
Fix it by checking for this case and returning -EINVAL.
[AV: what we want is is_mounted(); use that instead of making the
condition even more convoluted]
Reproducer:
#include <unistd.h>
#define __NR_move_mount 429
#define MOVE_MOUNT_F_EMPTY_PATH 0x00000004
int main()
{
int fds[2];

I'm not entirely sure why this is, but for some reason:
921935dc6404 ("drm/amd/powerplay: enforce display related settings only on needed")
Breaks runtime PM resume on the Radeon PRO WX 3100 (Lexa) in one the
pre-production laptops I have. The issue manifests as the following
messages in dmesg:
[drm] UVD and UVD ENC initialized successfully.
amdgpu 0000:3b:00.0: [drm:amdgpu_ring_test_helper [amdgpu]] *ERROR* ring vce1 test failed (-110)
[drm:amdgpu_device_ip_resume_phase2 [amdgpu]] *ERROR* resume of IP block <vce_v3_0> failed -110
[drm:amdgpu_device_resume [amdgpu]] *ERROR* amdgpu_device_ip_resume failed (-110).
And happens after about 6-10 runtime PM suspend/resume cycles (sometimes
sooner, if you're lucky!). Unfortunately I can't seem to pin down
precisely which part in psm_adjust_power_state_dynamic that is causing
the issue, but not skipping the display setting setup seems to fix it.
Hopefully if there is a better fix for this, this patch will spark
discussion around it.

If MTD_NAND_JZ4780 is y and MTD_NAND_JZ4780_BCH is m,
which select CONFIG_MTD_NAND_INGENIC_ECC to m, building fails:
drivers/mtd/nand/raw/ingenic/ingenic_nand.o: In function `ingenic_nand_remove':
ingenic_nand.c:(.text+0x177): undefined reference to `ingenic_ecc_release'
drivers/mtd/nand/raw/ingenic/ingenic_nand.o: In function `ingenic_nand_ecc_correct':
ingenic_nand.c:(.text+0x2ee): undefined reference to `ingenic_ecc_correct'
To fix that, the ingenic_nand and ingenic_ecc modules have been fused
into one single module.
- The ingenic_ecc.c code is now compiled in only if
$(CONFIG_MTD_NAND_INGENIC_ECC) is set. This is now a boolean instead
of tristate.
- To avoid changing the module name, the ingenic_nand.c file is moved to
ingenic_nand_drv.c. Then the module name is still ingenic_nand.
- Since ingenic_ecc.c is no more a module, the module-specific macros
have been dropped, and the functions are no more exported for use by
the ingenic_nand driver.
