git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull ftrace fixes from Steven Rostedt: - Add needed READ_ONCE() around access to the fgraph array element The updates to the fgraph array can happen when callbacks are registered and unregistered. The __ftrace_return_to_handler() can handle reading either the old value or the new value. But once it reads that value it must stay consistent otherwise the check that looks to see if the value is a stub may show false, but if the compiler decides to re-read after that check, it can be true which can cause the code to crash later on. - Make function profiler use the top level ops for filtering again When function graph became available for instances, its filter ops became independent from the top level set_ftrace_filter. In the process the function profiler received its own filter ops as well. But the function profiler uses the top level set_ftrace_filter file and does not have one of its own. In giving it its own filter ops, it lost any user interface it once had. Make it use the top level set_ftrace_filter file again.

2025-01-02ftrace: Fix function profiler's filtering functionalityKohei Enju
Commit c132be2c4fcc ("function_graph: Have the instances use their own ftrace_ops for filtering"), function profiler (enabled via function_profile_enabled) has been showing statistics for all functions, ignoring set_ftrace_filter settings. While tracers are instantiated, the function profiler is not. Therefore, it should use the global set_ftrace_filter for consistency. This patch modifies the function profiler to use the global filter, fixing the filtering functionality.

2025-01-02fgraph: Add READ_ONCE() when accessing fgraph_array[]Zilin Guan
In __ftrace_return_to_handler(), a loop iterates over the fgraph_array[] elements, which are fgraph_ops. The loop checks if an element is a fgraph_stub to prevent using a fgraph_stub afterward. However, if the compiler reloads fgraph_array[] after this check, it might race with an update to fgraph_array[] that introduces a fgraph_stub. This could result in the stub being processed, but the stub contains a null "func_hash" field, leading to a NULL pointer dereference. To ensure that the gops compared against the fgraph_stub matches the gops processed later, add a READ_ONCE(). A similar patch appears in commit 63a8dfb ("function_graph: Add READ_ONCE() when accessing fgraph_array[]").

2025-01-02xe/oa: Fix query mode of operation for OAR/OACUmesh Nerlige Ramappa
This is a set of squashed commits to facilitate smooth applying to stable. Each commit message is retained for reference. 1) Allow a GGTT mapped batch to be submitted to user exec queue For a OA use case, one of the HW registers needs to be modified by submitting an MI_LOAD_REGISTER_IMM command to the users exec queue, so that the register is modified in the user's hardware context. In order to do this a batch that is mapped in GGTT, needs to be submitted to the user exec queue. Since all user submissions use q->vm and hence PPGTT, add some plumbing to enable submission of batches mapped in GGTT. v2: ggtt is zero-initialized, so no need to set it false (Matt Brost) 2) xe/oa: Use MI_LOAD_REGISTER_IMMEDIATE to enable OAR/OAC To enable OAR/OAC, a bit in RING_CONTEXT_CONTROL needs to be set. Setting this bit cause the context image size to change and if not done correct, can cause undesired hangs. Current code uses a separate exec_queue to modify this bit and is error-prone. As per HW recommendation, submit MI_LOAD_REGISTER_IMM to the target hardware context to modify the relevant bit. In v2 version, an attempt to submit everything to the user-queue was made, but it failed the unprivileged-single-ctx-counters test. It appears that the OACTXCONTROL must be modified from a remote context. In v3 version, all context specific register configurations were moved to use LOAD_REGISTER_IMMEDIATE and that seems to work well. This is a cleaner way, since we can now submit all configuration to user exec_queue and the fence handling is simplified. v2: (Matt) - set job->ggtt to true if create job is successful - unlock vm on job error (Ashutosh) - don't wait on job submission - use kernel exec queue where possible v3: (Ashutosh) - Fix checkpatch issues - Remove extra spaces/new-lines - Add Fixes: and Cc: tags - Reset context control bit when OA stream is closed - Submit all config via MI_LOAD_REGISTER_IMMEDIATE (Umesh) - Update commit message for v3 experiment - Squash patches for easier port to stable v4: (Ashutosh) - No need to pass q to xe_oa_submit_bb - Do not support exec queues with width > 1 - Fix disabling of CTX_CTRL_OAC_CONTEXT_ENABLE v5: (Ashutosh) - Drop reg_lri related comments - Use XE_OA_SUBMIT_NO_DEPS in xe_oa_load_with_lri Fixes: 8135f1c09dd2 ("drm/xe/oa: Don't reset OAC_CONTEXT_ENABLE on OA stream close") Signed-off-by: Umesh Nerlige Ramappa <umesh.nerlige.ramappa@intel.com> Reviewed-by: Matthew Brost <matthew.brost@intel.com> # commit 1 Reviewed-by: Ashutosh Dixit <ashutosh.dixit@intel.com> Cc: stable@vger.kernel.org Reviewed-by: Jonathan Cavitt <jonathan.cavitt@intel.com> Signed-off-by: Ashutosh Dixit <ashutosh.dixit@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20241220171919.571528-2-umesh.nerlige.ramappa@intel.com (cherry picked from commit 55039832f98c7e05f1cf9e0d8c12b2490abd0f16) Signed-off-by: Thomas Hellström <thomas.hellstrom@linux.intel.com>

2024-12-31tracing: Have process_string() also allow arraysSteven Rostedt
In order to catch a common bug where a TRACE_EVENT() TP_fast_assign() assigns an address of an allocated string to the ring buffer and then references it in TP_printk(), which can be executed hours later when the string is free, the function test_event_printk() runs on all events as they are registered to make sure there's no unwanted dereferencing. It calls process_string() to handle cases in TP_printk() format that has "%s". It returns whether or not the string is safe. But it can have some false positives. For instance, xe_bo_move() has: TP_printk("move_lacks_source:%s, migrate object %p [size %zu] from %s to %s device_id:%s", __entry->move_lacks_source ? "yes" : "no", __entry->bo, __entry->size, xe_mem_type_to_name[__entry->old_placement], xe_mem_type_to_name[__entry->new_placement], __get_str(device_id)) Where the "%s" references into xe_mem_type_to_name[].

2024-12-30Revert "ALSA: ump: Don't enumeration invalid groups for legacy rawmidi"Takashi Iwai
This reverts commit c2d188e137e77294323132a760a4608321a36a70. Although it's fine to filter the invalid UMP groups at the first probe time, this will become a problem when UMP groups are updated and (re-)activated. Then there is no way to re-add the substreams properly for the legacy rawmidi, and the new active groups will be still invisible. So let's revert the change. This will move back to showing the full 16 groups, but it's better than forever lost. Link: https://patch.msgid.link/20241230114023.3787-1-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>

OSS sequencer handles the SysEx messages split in 6 bytes packets, and ALSA sequencer OSS layer tries to combine those. It stores the data in the internal buffer and this access is racy as of now, which may lead to the out-of-bounds access. As a temporary band-aid fix, introduce a mutex for serializing the process of the SysEx message packets.

The HP OMEN 8 (2022), corresponding to a board ID of 8A15, supports OMEN thermal profile and requires the timed profile quirk. Upon adding this ID to both the omen_thermal_profile_boards and omen_timed_thermal_profile_boards, significant bump in performance can be observed. For instance, SilverBench (https://silver.urih.com/) results improved from ~56,000 to ~69,000, as a result of higher power draws (and thus core frequencies) whilst under load: Package Power: - Before the patch: ~65W (dropping to about 55W under sustained load). - After the patch: ~115W (dropping to about 105W under sustained load). Core Power: - Before: ~60W (ditto above). - After: ~108W (ditto above). Add 8A15 to omen_thermal_profile_boards and omen_timed_thermal_profile_boards to improve performance.

2024-12-29virt: tdx-guest: Just leak decrypted memory on unrecoverable errorsLi RongQing
In CoCo VMs it is possible for the untrusted host to cause set_memory_decrypted() to fail such that an error is returned and the resulting memory is shared. Callers need to take care to handle these errors to avoid returning decrypted (shared) memory to the page allocator, which could lead to functional or security issues. Leak the decrypted memory when set_memory_decrypted() fails, and don't need to print an error since set_memory_decrypted() will call WARN_ONCE().

2024-12-29x86/fred: Clear WFE in missing-ENDBRANCH #CPsXin Li (Intel)
An indirect branch instruction sets the CPU indirect branch tracker (IBT) into WAIT_FOR_ENDBRANCH (WFE) state and WFE stays asserted across the instruction boundary. When the decoder finds an inappropriate instruction while WFE is set ENDBR, the CPU raises a #CP fault. For the "kernel IBT no ENDBR" selftest where #CPs are deliberately triggered, the WFE state of the interrupted context needs to be cleared to let execution continue. Otherwise when the CPU resumes from the instruction that just caused the previous #CP, another missing-ENDBRANCH #CP is raised and the CPU enters a dead loop. This is not a problem with IDT because it doesn't preserve WFE and IRET doesn't set WFE. But FRED provides space on the entry stack (in an expanded CS area) to save and restore the WFE state, thus the WFE state is no longer clobbered, so software must clear it. Clear WFE to avoid dead looping in ibt_clear_fred_wfe() and the !ibt_fatal code path when execution is allowed to continue. Clobbering WFE in any other circumstance is a security-relevant bug.

2024-12-29freezer, sched: Report frozen tasks as 'D' instead of 'R'Chen Ridong
Before commit: f5d39b020809 ("freezer,sched: Rewrite core freezer logic") the frozen task stat was reported as 'D' in cgroup v1. However, after rewriting the core freezer logic, the frozen task stat is reported as 'R'. This is confusing, especially when a task with stat of 'S' is frozen. This bug can be reproduced with these steps: $ cd /sys/fs/cgroup/freezer/ $ mkdir test $ sleep 1000 & [1] 739 // task whose stat is 'S' $ echo 739 > test/cgroup.procs $ echo FROZEN > test/freezer.state $ ps -aux | grep 739 root 739 0.1 0.0 8376 1812 pts/0 R 10:56 0:00 sleep 1000 As shown above, a task whose stat is 'S' was changed to 'R' when it was frozen. To solve this regression, simply maintain the same reported state as before the rewrite.
