2025-01-10poll_wait: kill the obsolete wait_address checkOleg Nesterov
This check is historical and no longer needed, wait_address is never NULL. These days we rely on the poll_table->_qproc check. NULL if select/poll is not going to sleep, or it already has a data to report, or all waiters have already been registered after the 1st iteration. However, poll_table *p can be NULL, see p9_fd_poll() for example, so we can't remove the "p != NULL" check.

2025-01-10poll_wait: add mb() to fix theoretical race between waitqueue_active() and ↵Oleg Nesterov
.poll() As the comment above waitqueue_active() explains, it can only be used if both waker and waiter have mb()'s that pair with each other. However __pollwait() is broken in this respect. This is not pipe-specific, but let's look at pipe_poll() for example: poll_wait(...); // -> __pollwait() -> add_wait_queue() LOAD(pipe->head); LOAD(pipe->head); In theory these LOAD()'s can leak into the critical section inside add_wait_queue() and can happen before list_add(entry, wq_head), in this case pipe_poll() can race with wakeup_pipe_readers/writers which do smp_mb(); if (waitqueue_active(wq_head)) wake_up_interruptible(wq_head); There are more __pollwait()-like functions (grep init_poll_funcptr), and it seems that at least ep_ptable_queue_proc() has the same problem, so the patch adds smp_mb() into poll_wait().

2025-01-10drm/ttm: Handle cgroup based eviction in TTMMaarten Lankhorst
cgroup resource allocation has to be handled in TTM, so -EAGAIN from cgroups can be converted into -ENOSPC, and the limitcg can be properly evicted in ttm code. When hitting a resource limit through -EAGAIN, the cgroup for which the limit is hit is also returned. This allows eviction to delete only from cgroups which are a subgroup of the current cgroup. The returned CSS is used to determine if eviction is valuable for a given resource, and allows TTM to only target specific resources to lower memory usage.

2025-01-10fs: debugfs: fix open proxy for unsafe filesJohannes Berg
In the previous commit referenced below, I had to split the short fops handling into different proxy fops. This necessitated knowing out-of-band whether or not the ops are short or full, when attempting to convert from fops to allocated fsdata. Unfortunately, I only converted full_proxy_open() which is used for the new full_proxy_open_regular() and full_proxy_open_short(), but forgot about the call in open_proxy_open(), used for debugfs_create_file_unsafe(). Fix that, it never has short fops.

2025-01-09net: ethernet: ti: cpsw_ale: Fix cpsw_ale_get_field()Sudheer Kumar Doredla
CPSW ALE has 75-bit ALE entries stored across three 32-bit words. The cpsw_ale_get_field() and cpsw_ale_set_field() functions support ALE field entries spanning up to two words at the most. The cpsw_ale_get_field() and cpsw_ale_set_field() functions work as expected when ALE field spanned across word1 and word2, but fails when ALE field spanned across word2 and word3. For example, while reading the ALE field spanned across word2 and word3 (i.e. bits 62 to 64), the word3 data shifted to an incorrect position due to the index becoming zero while flipping. The same issue occurred when setting an ALE entry. This issue has not been seen in practice but will be an issue in the future if the driver supports accessing ALE fields spanning word2 and word3 Fix the methods to handle getting/setting fields spanning up to two words.

2025-01-09scsi: core: Fix command pass through retry regressionMike Christie
scsi_check_passthrough() is always called, but it doesn't check for if a command completed successfully. As a result, if a command was successful and the caller used SCMD_FAILURE_RESULT_ANY to indicate what failures it wanted to retry, we will end up retrying the command. This will cause delays during device discovery because of the command being sent multiple times. For some USB devices it can also cause the wrong device size to be used. This patch adds a check for if the command was successful. If it is we return immediately instead of trying to match a failure.

2025-01-09drm/amdgpu/gfx10: Enable cleaner shader for GFX10.3.2/10.3.4/10.3.5 GPUsSrinivasan Shanmugam
Enable the cleaner shader for GFX10.3.2/10.3.4/10.3.5 GPUs to provide data isolation between GPU workloads. The cleaner shader is responsible for clearing the Local Data Store (LDS), Vector General Purpose Registers (VGPRs), and Scalar General Purpose Registers (SGPRs), which helps prevent data leakage and ensures accurate computation results. This update extends cleaner shader support to GFX10.3.2/10.3.4/10.3.5 GPUs, previously available for GFX10.3.0. It enhances security by clearing GPU memory between processes and maintains a consistent GPU state across KGD and KFD workloads.

2025-01-09drm/amdgpu: Fix shift type in amdgpu_debugfs_sdma_sched_mask_set()Dan Carpenter
The "mask" and "val" variables are type u64. The problem is that the BIT() macros are type unsigned long which is just 32 bits on 32bit systems. It's unlikely that people will be using this driver on 32bit kernels and even if they did we only use the lower AMDGPU_MAX_SDMA_INSTANCES (16) bits. So this bug does not affect anything in real life. Still, for correctness sake, u64 bit masks should use BIT_ULL().

testing with clang Commit 24909d9ec7c3 ("drm/amd/display: Overwriting dualDPP UBF values before usage") added a new warning in dml2/display_mode_core.c when building allmodconfig with clang: drivers/gpu/drm/amd/amdgpu/../display/dc/dml2/display_mode_core.c:6268:13: error: stack frame size (3128) exceeds limit (3072) in 'dml_prefetch_check' [-Werror,-Wframe-larger-than] 6268 | static void dml_prefetch_check(struct display_mode_lib_st *mode_lib) | ^ Commit be4e3509314a ("drm/amd/display: DML21 Reintegration For Various Fixes") introduced one in dml2_core/dml2_core_dcn4_calcs.c with the same configuration: drivers/gpu/drm/amd/amdgpu/../display/dc/dml2/dml21/src/dml2_core/dml2_core_dcn4_calcs.c:7236:13: error: stack frame size (3256) exceeds limit (3072) in 'dml_core_mode_support' [-Werror,-Wframe-larger-than] 7236 | static bool dml_core_mode_support(struct dml2_core_calcs_mode_support_ex *in_out_params) | ^ In the case of the first warning, the stack usage was already at the limit at the parent change, so the offending change was rather innocuous. In the case of the second warning, there was a rather dramatic increase in stack usage compared to the parent: drivers/gpu/drm/amd/amdgpu/../display/dc/dml2/dml21/src/dml2_core/dml2_core_dcn4_calcs.c:7032:13: error: stack frame size (2696) exceeds limit (2048) in 'dml_core_mode_support' [-Werror,-Wframe-larger-than] 7032 | static bool dml_core_mode_support(struct dml2_core_calcs_mode_support_ex *in_out_params) | ^ This is an unfortunate interaction between an issue with stack slot reuse in LLVM that gets exacerbated by sanitization (which gets enabled with all{mod,yes}config) and function calls using a much higher number of parameters than is typical in the kernel, necessitating passing most of these values on the stack. While it is possible that there should be source code changes to address these warnings, this code is difficult to modify for various reasons, as has been noted in other changes that have occurred for similar reasons, such as commit 6740ec97bcdb ("drm/amd/display: Increase frame warning limit with KASAN or KCSAN in dml2"). Increase the frame larger than limit when compile testing with clang and the sanitizers enabled to avoid this breakage in all{mod,yes}config, as they are commonly used and valuable testing targets. While it is not the best to hide this issue, it is not really relevant when compile testing, as the sanitizers are commonly stressful on optimizations and they are only truly useful at runtime, which COMPILE_TEST states will not occur with the current build.
