2025-09-24libie: fix string names for AQ error codesJacob Keller1-1/+1
The LIBIE_AQ_STR macro() introduced by commit 5feaa7a07b85 ("libie: add adminq helper for converting err to str") is used in order to generate strings for printing human readable error codes. Its definition is missing the separating underscore ('_') character which makes the resulting strings difficult to read. Additionally, the string won't match the source code, preventing search tools from working properly. Add the missing underscore character, fixing the error string names.

2025-09-24crypto: af_alg - Fix incorrect boolean values in af_alg_ctxEric Biggers1-1/+1
Commit 1b34cbbf4f01 ("crypto: af_alg - Disallow concurrent writes in af_alg_sendmsg") changed some fields from bool to 1-bit bitfields of type u32. However, some assignments to these fields, specifically 'more' and 'merge', assign values greater than 1. These relied on C's implicit conversion to bool, such that zero becomes false and nonzero becomes true. With a 1-bit bitfields of type u32 instead, mod 2 of the value is taken instead, resulting in 0 being assigned in some cases when 1 was intended. Fix this by restoring the bool type.

2025-09-24kbuild: Disable CC_HAS_ASM_GOTO_OUTPUT on clang < 17Thomas Gleixner1-0/+3
clang < 17 fails to use scope local labels with CONFIG_CC_HAS_ASM_GOTO_OUTPUT=y: { __label__ local_lbl; ... unsafe_get_user(uval, uaddr, local_lbl); ... return 0; local_lbl: return -EFAULT; } when two such scopes exist in the same function: error: cannot jump from this asm goto statement to one of its possible targets There are other failure scenarios. Shuffling code around slightly makes it worse and fail even with one instance. That issue prevents using local labels for a cleanup based user access mechanism. After failed attempts to provide a simple enough test case for the 'depends on' test in Kconfig, the initial cure was to mark ASM goto broken on clang versions < 17 to get this road block out of the way. But Nathan pointed out that this is a known clang issue and indeed affects clang < version 17 in combination with cleanup(). It's not even required to use local labels for that. The clang issue tracker has a small enough test case, which can be used as a test in the 'depends on' section of CC_HAS_ASM_GOTO_OUTPUT: void bar(void **); void* baz(void); int foo (void) { { asm goto("jmp %l0"::::l0); return 0; l0: return 1; } void *x __attribute__((cleanup(bar))) = baz(); { asm goto("jmp %l0"::::l1); return 42; l1: return 0xff; } } Add another dependency to config CC_HAS_ASM_GOTO_OUTPUT for it and use the clang issue tracker test case for detection by condensing it to obfuscated C-code contest format. This reliably catches the problem on clang < 17 and did not show any issues on the non broken GCC versions. That test might be sufficient to catch all issues and therefore could replace the existing test, but keeping that around does no harm either. Thanks to Nathan for pointing to the relevant clang issue!

2025-09-24futex: Use correct exit on failure from futex_hash_allocate_default()Sebastian Andrzej Siewior1-1/+1
copy_process() uses the wrong error exit path from futex_hash_allocate_default(). After exiting from futex_hash_allocate_default(), neither tasklist_lock nor siglock has been acquired. The exit label bad_fork_core_free unlocks both of these locks which is wrong. The next exit label, bad_fork_cancel_cgroup, is the correct exit. sched_cgroup_fork() did not allocate any resources that need to freed. Use bad_fork_cancel_cgroup on error exit from futex_hash_allocate_default().

2025-09-23net: allow alloc_skb_with_frags() to use MAX_SKB_FRAGSJason Baron1-1/+1
Currently, alloc_skb_with_frags() will only fill (MAX_SKB_FRAGS - 1) slots. I think it should use all MAX_SKB_FRAGS slots, as callers of alloc_skb_with_frags() will size their allocation of frags based on MAX_SKB_FRAGS. This issue was discovered via a test patch that sets 'order' to 0 in alloc_skb_with_frags(), which effectively tests/simulates high fragmentation. In this case sendmsg() on unix sockets will fail every time for large allocations. If the PAGE_SIZE is 4K, then data_len will request 68K or 17 pages, but alloc_skb_with_frags() can only allocate 64K in this case or 16 pages.

2025-09-23drm/amd/display: Only restore backlight after amdgpu_dm_init or dm_resumeMatthew Schwartz2-4/+15
On clients that utilize AMD_PRIVATE_COLOR properties for HDR support, brightness sliders can include a hardware controlled portion and a gamma-based portion. This is the case on the Steam Deck OLED when using gamescope with Steam as a client. When a user sets a brightness level while HDR is active, the gamma-based portion and/or hardware portion are adjusted to achieve the desired brightness. However, when a modeset takes place while the gamma-based portion is in-use, restoring the hardware brightness level overrides the user's overall brightness level and results in a mismatch between what the slider reports and the display's current brightness. To avoid overriding gamma-based brightness, only restore HW backlight level after boot or resume. This ensures that the backlight level is set correctly after the DC layer resets it while avoiding interference with subsequent modesets.

2025-09-23btrfs: zoned: don't fail mount needlessly due to too many active zonesJohannes Thumshirn1-0/+6
Previously BTRFS did not look at a device's reported max_open_zones limit, but starting with commit 04147d8394e8 ("btrfs: zoned: limit active zones to max_open_zones"), zoned BTRFS limited the number of concurrently used block-groups to the number of max_open_zones a device reported, if it hadn't already reported a number of max_active_zones. Starting with commit 04147d8394e8 the number of open zones is treated the same way as active zones. But this leads to mount failures on filesystems which have been used before 04147d8394e8 because too many zones are in an open state. Ignore the new limitations on these filesystems, so zones can be finished or evacuated.

In shmem_pwrite(), this error is later masked as -EIO due to the error handling order, leading to igt failures like gen9_exec_parse(bb-large). Set O_LARGEFILE in __create_shmem() to prevent -EFBIG on large writes.

2025-09-22bnxt_en: correct offset handling for IPv6 destination addressAlok Tiwari1-1/+1
In bnxt_tc_parse_pedit(), the code incorrectly writes IPv6 destination values to the source address field (saddr) when processing pedit offsets within the destination address range. This patch corrects the assignment to use daddr instead of saddr, ensuring that pedit operations on IPv6 destination addresses are applied correctly.

2025-09-22x86/topology: Implement topology_is_core_online() to address SMT regressionThomas Gleixner2-0/+23
Christian reported that commit a430c11f4015 ("intel_idle: Rescan "dead" SMT siblings during initialization") broke the use case in which both 'nosmt' and 'maxcpus' are on the kernel command line because it onlines primary threads, which were offline due to the maxcpus limit. The initially proposed fix to skip primary threads in the loop is inconsistent. While it prevents the primary thread to be onlined, it then onlines the corresponding hyperthread(s), which does not really make sense. The CPU iterator in cpuhp_smt_enable() contains a check which excludes all threads of a core, when the primary thread is offline. The default implementation is a NOOP and therefore not effective on x86. Implement topology_is_core_online() on x86 to address this issue. This makes the behaviour consistent between x86 and PowerPC.
