2023-04-27intel_idle: improve C-state flags handling robustnessArtem Bityutskiy1-10/+18
The following C-state flags are currently mutually-exclusive and should not be combined: * IRQ_ENABLE * IBRS * XSTATE There is a warning for the situation when the IRQ_ENABLE flag is combined with the IBRS flag, but no warnings for other combinations. This is inconsistent and prone to errors. Improve the situation by adding warnings for all the unexpected combinations. Add a couple of helpful commentaries too.

2023-04-27intel_idle: further intel_idle_init_cstates_icpu() cleanupArtem Bityutskiy1-11/+13
Introduce a temporary 'state' variable for referencing the currently processed C-state in the intel_idle_init_cstates_icpu() function. This makes code lines shorter and easier to read.

2023-04-27intel_idle: clean up intel_idle_init_cstates_icpu()Artem Bityutskiy1-5/+5
The intel_idle_init_cstates_icpu() function includes a loop that iterates over every C-state. Inside the loop, the same C-state data is referenced 2 ways: 1. as cpuidle_state_table[cstate] 2. as drv->states[drv->state_count] (but it is a copy of #1, not the same object). Make the code be more consistent and easier to read by using only the 2nd way. So the code structure would be as follows: 1. Use cpuidle_state_table[cstate] 2. Copy cpuidle_state_table[cstate] to drv->states[drv->state_count] 3. Use only drv->states[drv->state_count] from this point. Note, this change introduces a checkpatch.pl warning (too long line), but it will be addressed in the next patch.

2023-04-27ACPI: thermal: Move to dedicated function sysfs extra attr creationDaniel Lezcano1-19/+31
The ACPI thermal driver creates extra sysfs attributes in its own directory pointing to the thermal zone it is related to and add a pointer to the sysfs ACPI thermal device from the thermal zone sysfs entry. This is very specific to this ACPI thermal driver, let's encapsulate the related creation/deletion code to group it inside a function we can identify later for removal if needed.

2023-04-27thermal: core: Encapsulate tz->device fieldDaniel Lezcano2-0/+7
There are still some drivers needing to play with the thermal zone device internals. That is not the best but until we can figure out if the information is really needed, let's encapsulate the field used in the thermal zone device structure, so we can move forward relocating the thermal zone device structure definition in the thermal framework private headers. Some drivers are accessing tz->device, that implies they need to have the knowledge of the thermal_zone_device structure but we want to self-encapsulate this structure and reduce the scope of the structure to the thermal core only. By adding this wrapper, these drivers won't need the thermal zone device structure definition and are no longer an obstacle to its relocation to the private thermal core headers.

2023-04-27PM: hibernate: Do not get block device exclusively in test_resume modeChen Yu2-4/+12
The system refused to do a test_resume because it found that the swap device has already been taken by someone else. Specifically, the swsusp_check()->blkdev_get_by_dev(FMODE_EXCL) is supposed to do this check. Steps to reproduce: dd if=/dev/zero of=/swapfile bs=$(cat /proc/meminfo | awk '/MemTotal/ {print $2}') count=1024 conv=notrunc mkswap /swapfile swapon /swapfile swap-offset /swapfile echo 34816 > /sys/power/resume_offset echo test_resume > /sys/power/disk echo disk > /sys/power/state PM: Using 3 thread(s) for compression PM: Compressing and saving image data (293150 pages)...

This is not an issue for normal hibernation, because software_resume()->swsusp_check() happens before the block device(rootfs) mount. But it is a problem for the test_resume mode. Because when test_resume happens, the block device has been mounted already. Thus remove the FMODE_EXCL for test_resume mode. This would not be a problem because in test_resume stage, the processes have already been frozen, and the race condition described in Commit 39fbef4b0f77 ("PM: hibernate: Get block device exclusively in swsusp_check()") is unlikely to happen.

2023-04-27ACPI: PM: Do not turn of unused power resources on the Toshiba Click MiniHans de Goede1-0/+19
The CPR3 power resource on the Toshiba Click Mini toggles a GPIO which is called SISP (for SIS touchscreen power?) on/off. This CPR3 power resource is not listed in any _PR? lists, let alone in a _PR0 list for the SIS0817 touchscreen ACPI device which needs it. Before commit a1224f34d72a ("ACPI: PM: Check states of power resources during initialization") this was not an issue because since nothing referenced the CPR3 power resource its state was always ACPI_POWER_RESOURCE_STATE_UNKNOWN and power resources with this state get ignored by acpi_turn_off_unused_power_resources(). This clearly is a bug in the DSDT of this device. Add a DMI quirk to make acpi_turn_off_unused_power_resources() a no-op on this model to fix the touchscreen no longer working since kernel 5.16 . This quirk also causes 2 other power resources to not get turned off, but the _OFF method on these already was a no-op, so this makes no difference for the other 2 power resources.

2023-04-27mm/mremap: fix vm_pgoff in vma_merge() case 3Vlastimil Babka1-1/+1
After upgrading build guests to v6.3, rpm started segfaulting for specific packages, which was bisected to commit 0503ea8f5ba7 ("mm/mmap: remove __vma_adjust()"). rpm is doing many mremap() operations with file mappings of its db. The problem is that in vma_merge() case 3 (we merge with the next vma, expanding it downwards) vm_pgoff is not adjusted as it should when vm_start changes. As a result the rpm process most likely sees data from the wrong offset of the file. Fix the vm_pgoff calculation. For case 8 this is a non-functional change as the resulting vm_pgoff is the same.

After creating SecYs, SCs and SAs a SecY can be modified to change attributes like validation mode, protect frames mode etc. During this SecY update, packet number is reset to initial user given value by mistake.

Commit 4fe815850bdc ("ixgbe: let the xdpdrv work with more than 64 cpus") adds support to allow XDP programs to run on systems with more than 64 CPUs by locking the XDP TX rings and indexing them using cpu % 64 (IXGBE_MAX_XDP_QS). Upon trying this out patch on a system with more than 64 cores, the kernel paniced with an array-index-out-of-bounds at the return in ixgbe_determine_xdp_ring in ixgbe.h, which means ixgbe_determine_xdp_q_idx was just returning the cpu instead of cpu % IXGBE_MAX_XDP_QS.

However, immediately after this, the rings are reconfigured by ixgbe_setup_tc. ixgbe_setup_tc calls ixgbe_clear_interrupt_scheme which calls ixgbe_free_q_vectors which calls ixgbe_free_q_vector in a loop. ixgbe_free_q_vector decrements ixgbe_xdp_locking_key once per call if it is non-zero. Commenting out the decrement in ixgbe_free_q_vector stopped my system from panicing. I suspect to make the original patch work, I would need to load an XDP program and then replace it in order to get ixgbe_xdp_locking_key back above 0 since ixgbe_setup_tc is only called when transitioning between XDP and non-XDP ring configurations, while ixgbe_xdp_locking_key is incremented every time ixgbe_xdp_setup is called. Also, ixgbe_setup_tc can be called via ethtool --set-channels, so this becomes another path to decrement ixgbe_xdp_locking_key to 0 on systems with more than 64 CPUs. Since ixgbe_xdp_locking_key only protects the XDP_TX path and is tied to the number of CPUs present, there is no reason to disable it upon unloading an XDP program. To avoid confusion, I have moved enabling ixgbe_xdp_locking_key into ixgbe_sw_init, which is part of the probe path.

2023-04-27net/sched: flower: Fix wrong handle assignment during filter changeIvan Vecera1-1/+1
Commit 08a0063df3ae ("net/sched: flower: Move filter handle initialization earlier") moved filter handle initialization but an assignment of the handle to fnew->handle is done regardless of fold value. This is wrong because if fold != NULL (so fold->handle == handle) no new handle is allocated and passed handle is assigned to fnew->handle. Then if any subsequent action in fl_change() fails then the handle value is removed from IDR that is incorrect as we will have still valid old filter instance with handle that is not present in IDR. Fix this issue by moving the assignment so it is done only when passed fold == NULL.

2023-04-27rxrpc: Fix potential data race in rxrpc_wait_to_be_connected()David Howells1-8/+4
Inside the loop in rxrpc_wait_to_be_connected() it checks call->error to see if it should exit the loop without first checking the call state. This is probably safe as if call->error is set, the call is dead anyway, but we should probably wait for the call state to have been set to completion first, lest it cause surprise on the way out. Fix this by only accessing call->error if the call is complete. We don't actually need to access the error inside the loop as we'll do that after. This caused the following report: BUG: KCSAN: data-race in rxrpc_send_data / rxrpc_set_call_completion write to 0xffff888159cf3c50 of 4 bytes by task 25673 on cpu 1: rxrpc_set_call_completion+0x71/0x1c0 net/rxrpc/call_state.c:22 rxrpc_send_data_packet+0xba9/0x1650 net/rxrpc/output.c:479 rxrpc_transmit_one+0x1e/0x130 net/rxrpc/output.c:714 rxrpc_decant_prepared_tx net/rxrpc/call_event.c:326 [inline] rxrpc_transmit_some_data+0x496/0x600 net/rxrpc/call_event.c:350 rxrpc_input_call_event+0x564/0x1220 net/rxrpc/call_event.c:464 rxrpc_io_thread+0x307/0x1d80 net/rxrpc/io_thread.c:461 kthread+0x1ac/0x1e0 kernel/kthread.c:376 ret_from_fork+0x1f/0x30 arch/x86/entry/entry_64.S:308 read to 0xffff888159cf3c50 of 4 bytes by task 25672 on cpu 0: rxrpc_send_data+0x29e/0x1950 net/rxrpc/sendmsg.c:296 rxrpc_do_sendmsg+0xb7a/0xc20 net/rxrpc/sendmsg.c:726 rxrpc_sendmsg+0x413/0x520 net/rxrpc/af_rxrpc.c:565 sock_sendmsg_nosec net/socket.c:724 [inline] sock_sendmsg net/socket.c:747 [inline] ____sys_sendmsg+0x375/0x4c0 net/socket.c:2501 ___sys_sendmsg net/socket.c:2555 [inline] __sys_sendmmsg+0x263/0x500 net/socket.c:2641 __do_sys_sendmmsg net/socket.c:2670 [inline] __se_sys_sendmmsg net/socket.c:2667 [inline] __x64_sys_sendmmsg+0x57/0x60 net/socket.c:2667 do_syscall_x64 arch/x86/entry/common.c:50 [inline] do_syscall_64+0x41/0xc0 arch/x86/entry/common.c:80 entry_SYSCALL_64_after_hwframe+0x63/0xcd value changed: 0x00000000 -> 0xffffffea Fixes: 9d35d880e0e4 ("rxrpc: Move client call connection to the I/O thread") Reported-by: [email protected] Link: https://lore.kernel.org/r/[email protected]/ Signed-off-by: David Howells <[email protected]> cc: Marc Dionne <[email protected]> cc: Dmitry Vyukov <[email protected]> cc: "David S.

2023-04-26drm/amd/display: fix flickering caused by S/G modeHamza Mahfooz1-2/+11
Currently, on a handful of ASICs. We allow the framebuffer for a given plane to exist in either VRAM or GTT. However, if the plane's new framebuffer is in a different memory domain than it's previous framebuffer, flipping between them can cause the screen to flicker. So, to fix this, don't perform an immediate flip in the aforementioned case.
