2022-01-24xfrm: fix MTU regressionJiri Bohac1-4/+7
Commit 749439bfac6e1a2932c582e2699f91d329658196 ("ipv6: fix udpv6 sendmsg crash caused by too small MTU") breaks PMTU for xfrm. A Packet Too Big ICMPv6 message received in response to an ESP packet will prevent all further communication through the tunnel if the reported MTU minus the ESP overhead is smaller than 1280. E.g. in a case of a tunnel-mode ESP with sha256/aes the overhead is 92 bytes. Receiving a PTB with MTU of 1371 or less will result in all further packets in the tunnel dropped. A ping through the tunnel fails with "ping: sendmsg: Invalid argument". Apparently the MTU on the xfrm route is smaller than 1280 and fails the check inside ip6_setup_cork() added by 749439bf. We found this by debugging USGv6/ipv6ready failures. Failing tests are: "Phase-2 Interoperability Test Scenario IPsec" / 5.3.11 and 5.4.11 (Tunnel Mode: Fragmentation). Commit b515d2637276a3810d6595e10ab02c13bfd0b63a ("xfrm: xfrm_state_mtu should return at least 1280 for ipv6") attempted to fix this but caused another regression in TCP MSS calculations and had to be reverted. The patch below fixes the situation by dropping the MTU check and instead checking for the underflows described in the 749439bf commit message.

2022-01-24pinctrl: baytrail: Clear direct_irq_en flag on broken configsHans de Goede1-2/+53
Some boards set the direct_irq_en flag in the conf0 register without setting the correct trigger bits. The direct_irq_en flag just means that the GPIO will send IRQs directly to the APIC instead of going through the shared interrupt for the GPIO controller, in order for the pin to be able to actually generate IRQs the trigger flags must configure the IRQ as a level-high or level-low active IRQ. Note testing shows that using edge trigger add the conf0 register level does NOT work, instead edge triggering should be set at the IO-APIC level. I believe that the direct_irq_en flag connects the output of the GPIO's IRQ trigger block, which normally sets the status flag in the IRQ status reg at 0x800 to one of the IO-APIC pins according to the direct IRQ mux. This means that the TRIG_LVL bit *must* be set, so that the GPIO's input value is directly passed (1:1 or inverted) to the IO-APIC pin, if TRIG_LVL is not set, selecting edge mode operation then on the first edge the selected IO-APIC pin goes high, but since no write-to-clear write will be done to the IRQ status reg at 0x800, the detected edge condition will never get cleared. This APIC pin stuck high condition can be observed with the pin configured as level-high active, in the form of an interrupt storm. Clearing the TRIG_MASK bits of conf0 stops the storm, reconfiguring them as edge again results in a storm again as soon as the edge is triggered once. Detect invalid trigger flags, log a FW_BUG warning when encountering this and clear the direct_irq_en flag so that a driver can actually use the pin as IRQ through gpiod_to_irq(). Specifically this allows the edt-ft5x06 touchscreen driver to use INT33FC:02 pin 3 as touchscreen IRQ on the Nextbook Ares 8 tablet, accompanied by the following new log message byt_gpio INT33FC:02: [Firmware Bug]: pin 3: direct_irq_en set without trigger, clearing The new byt_direct_irq_sanity_check() function also checks that the pin is actually appointed to one of the 16 direct-IRQs which the GPIO controller supports and on success prints debug messages like these: byt_gpio INT33FC:02: Pin 0: uses direct IRQ 0 (IO-APIC 67) byt_gpio INT33FC:02: Pin 15: uses direct IRQ 2 (IO-APIC 69) This is useful to figure out the GPIO pin belonging to ACPI resources like this one: "Interrupt () { 0x00000043 }" or the other way around. The strict checking of valid trigger flags this introduces does result in FW_BUG messages on quite a few devices. E.g. on the Yoga Tablet 2 1051L: byt_gpio INT33FC:00: [Firmware Bug]: pin 92: direct_irq_en set but no IRQ assigned, clearing byt_gpio INT33FC:00: [Firmware Bug]: pin 93: direct_irq_en set but no IRQ assigned, clearing These 2 also have mux set to 7 and fall + rise + level trigger bits set, presumably something has written 0xffffffff to their conf0 registers byt_gpio INT33FC:02: Pin 3: uses direct IRQ 1 (IO-APIC 68) byt_gpio INT33FC:02: [Firmware Bug]: pin 3: direct_irq_en set without trigger (conf0: 2803cc00h), clearing Most tablets seem to have this, looking at DSDTs this seems intended for use with an I2C HID sensor-hub and is still set on devices without one.

2022-01-24pinctrl: intel: Fix a glitch when updating IRQ flags on a preconfigured lineAndy Shevchenko1-8/+2
The commit af7e3eeb84e2 ("pinctrl: intel: Disable input and output buffer when switching to GPIO") hadn't taken into account an update of the IRQ flags scenario. When updating the IRQ flags on the preconfigured line the ->irq_set_type() is called again. In such case the sequential Rx buffer configuration changes may trigger a falling or rising edge interrupt that may lead, on some platforms, to an undesired event. This may happen because each of intel_gpio_set_gpio_mode() and __intel_gpio_set_direction() updates the pad configuration with a different value of the GPIORXDIS bit. Notable, that the intel_gpio_set_gpio_mode() is called only for the pads that are configured as an input. Due to this fact, integrate the logic of __intel_gpio_set_direction() call into the intel_gpio_set_gpio_mode() so that the Rx buffer won't be disabled and immediately re-enabled.

2022-01-24pinctrl: intel: fix unexpected interruptŁukasz Bartosik1-20/+34
ASUS Chromebook C223 with Celeron N3350 crashes sometimes during cold booot. Inspection of the kernel log showed that it gets into an inifite loop logging the following message: ->handle_irq(): 000000009cdb51e8, handle_bad_irq+0x0/0x251 ->irq_data.chip(): 000000005ec212a7, 0xffffa043009d8e7 ->action(): 00000 IRQ_NOPROBE set unexpected IRQ trap at vector 7c The issue happens during cold boot but only if cold boot happens at most several dozen seconds after Chromebook is powered off. For longer intervals between power off and power on (cold boot) the issue does not reproduce. The unexpected interrupt is sourced from INT3452 GPIO pin which is used for SD card detect. Investigation relevealed that when the interval between power off and power on (cold boot) is less than several dozen seconds then values of INT3452 GPIO interrupt enable and interrupt pending registers survive power off and power on sequence and interrupt for SD card detect pin is enabled and pending during probe of SD controller which causes the unexpected IRQ message. "Intel Pentium and Celeron Processor N- and J- Series" volume 3 doc mentions that GPIO interrupt enable and status registers default value is 0x0. The fix clears INT3452 GPIO interrupt enabled and interrupt pending registers in its probe function.

2022-01-24video: hyperv_fb: Fix validation of screen resolutionMichael Kelley1-13/+3
In the WIN10 version of the Synthetic Video protocol with Hyper-V, Hyper-V reports a list of supported resolutions as part of the protocol negotiation. The driver calculates the maximum width and height from the list of resolutions, and uses those maximums to validate any screen resolution specified in the video= option on the kernel boot line. This method of validation is incorrect. For example, the list of supported resolutions could contain 1600x1200 and 1920x1080, both of which fit in an 8 Mbyte frame buffer. But calculating the max width and height yields 1920 and 1200, and 1920x1200 resolution does not fit in an 8 Mbyte frame buffer. Unfortunately, this resolution is accepted, causing a kernel fault when the driver accesses memory outside the frame buffer. Instead, validate the specified screen resolution by calculating its size, and comparing against the frame buffer size. Delete the code for calculating the max width and height from the list of resolutions, since these max values have no use. Also add the frame buffer size to the info message to aid in understanding why a resolution might be rejected.

2022-01-24KVM: VMX: Zero host's SYSENTER_ESP iff SYSENTER is NOT usedSean Christopherson1-3/+7
Zero vmcs.HOST_IA32_SYSENTER_ESP when initializing *constant* host state if and only if SYSENTER cannot be used, i.e. the kernel is a 64-bit kernel and is not emulating 32-bit syscalls. As the name suggests, vmx_set_constant_host_state() is intended for state that is *constant*. When SYSENTER is used, SYSENTER_ESP isn't constant because stacks are per-CPU, and the VMCS must be updated whenever the vCPU is migrated to a new CPU. The logic in vmx_vcpu_load_vmcs() doesn't differentiate between "never loaded" and "loaded on a different CPU", i.e. setting SYSENTER_ESP on VMCS load also handles setting correct host state when the VMCS is first loaded. Because a VMCS must be loaded before it is initialized during vCPU RESET, zeroing the field in vmx_set_constant_host_state() obliterates the value that was written when the VMCS was loaded. If the vCPU is run before it is migrated, the subsequent VM-Exit will zero out MSR_IA32_SYSENTER_ESP, leading to a #DF on the next 32-bit syscall. double fault: 0000 [#1] SMP CPU: 0 PID: 990 Comm: stable Not tainted 5.16.0+ #97 Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 0.0.0 02/06/2015 EIP: entry_SYSENTER_32+0x0/0xe7 Code: <9c> 50 eb 17 0f 20 d8 a9 00 10 00 00 74 0d 25 ff ef ff ff 0f 22 d8 EAX: 000000a2 EBX: a8d1300c ECX: a8d13014 EDX: 00000000 ESI: a8f87000 EDI: a8d13014 EBP: a8d12fc0 ESP: 00000000 DS: 007b ES: 007b FS: 0000 GS: 0000 SS: 0068 EFLAGS: 00210093 CR0: 80050033 CR2: fffffffc CR3: 02c3b000 CR4: 00152e90 Fixes: 6ab8a4053f71 ("KVM: VMX: Avoid to rdmsrl(MSR_IA32_SYSENTER_ESP)") Cc: Lai Jiangshan <laijs@linux.alibaba.com> Signed-off-by: Sean Christopherson <seanjc@google.com> Message-Id: <20220122015211.1468758-1-seanjc@google.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2022-01-24gpio: crystalcove: Set IRQ domain bus token to DOMAIN_BUS_WIREDHans de Goede1-1/+8
For the CRC PMIC we end up with multiple irq-domains with the same fwnode. One for the irqchip which demultiplexes the actual PMIC interrupt into interrupts for the various cells (known as the level 1 interrupts); And 2 more for the irqchips which are part of the crystal_cove_gpio and crystal_cove_charger cells. This leads to the following error being printed when CONFIG_GENERIC_IRQ_DEBUGFS is enabled: debugfs: File '\_SB.I2C7.PMIC' in directory 'domains' already present! Set the bus token of the main IRQ domain to DOMAIN_BUS_WIRED to avoid this error, this also allows irq_find_matching_fwspec() to find the right domain if necessary. Note all 3 domain registering drivers need to set the IRQ domain bus token. This is necessary because the IRQ domain code defaults to creating the debugfs dir with just the fwnode name and then renames it when the bus token is set. So each one starts with the same default name and all 3 must be given a different name to avoid problems when one of the other drivers loads and starts with the same default name.

When we fail to expand inode from inline format to a normal format, we restore inode to contain the original inline formatting but we forgot to set i_lenAlloc back. The mismatch between i_lenAlloc and i_size was then causing further problems such as warnings and lost data down the line.

2022-01-24udf: Fix NULL ptr deref when converting from inline formatJan Kara1-5/+3
udf_expand_file_adinicb() calls directly ->writepage to write data expanded into a page. This however misses to setup inode for writeback properly and so we can crash on inode->i_wb dereference when submitting page for IO like: BUG: kernel NULL pointer dereference, address: 0000000000000158 #PF: supervisor read access in kernel mode ... <TASK> __folio_start_writeback+0x2ac/0x350 __block_write_full_page+0x37d/0x490 udf_expand_file_adinicb+0x255/0x400 [udf] udf_file_write_iter+0xbe/0x1b0 [udf] new_sync_write+0x125/0x1c0 vfs_write+0x28e/0x400 Fix the problem by marking the page dirty and going through the standard writeback path to write the page.

2022-01-24spi: s3c24xx: Convert to GPIO descriptorsLinus Walleij2-49/+3
This driver has a bunch of custom oldstyle GPIO number-passing fields and a custom set-up callback. The good thing is: nothing in the kernel is using it. Convert the driver to use GPIO descriptors with a SPI_MASTER_GPIO_SS flag so that the local CS callback also get invoked as the hardware needs this. New users of this driver can provide GPIO descriptor tables like the other converted drivers.
