[PATCH v3 1/2] fs/proc: do_task_stat: Fix ESP not readable during coredump

by Nam Cao

The field "eip" (instruction pointer) and "esp" (stack pointer) of a task can be read from /proc/PID/stat. These fields can be interesting for coredump. However, these fields were disabled by commit 0a1eb2d474ed ("fs/proc: Stop reporting eip and esp in /proc/PID/stat"), because it is generally unsafe to do so. But it is safe for a coredumping process, and therefore exceptions were made: - for a coredumping thread by commit fd7d56270b52 ("fs/proc: Report eip/esp in /prod/PID/stat for coredumping"). - for all other threads in a coredumping process by commit cb8f381f1613 ("fs/proc/array.c: allow reporting eip/esp for all coredumping threads"). The above two commits check the PF_DUMPCORE flag to determine a coredump thread and the PF_EXITING flag for the other threads. Unfortunately, commit 92307383082d ("coredump: Don't perform any cleanups before dumping core") moved coredump to happen earlier and before PF_EXITING is set. Thus, checking PF_EXITING is no longer the correct way to determine threads in a coredumping process. Instead of PF_EXITING, use PF_POSTCOREDUMP to determine the other threads. Checking of PF_EXITING was added for coredumping, so it probably can now be removed. But it doesn't hurt to keep.

[PATCH v1] ftrace: Fix function profiler's filtering functionality

by Kohei Enju

From commit c132be2c4fcc ("function_graph: Have the instances use their own ftrace_ops for filtering"), function profiler (enabled via function_profil e_enabled) has been showing statistics for all functions, ignoring set_ftra ce_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.

[PATCH] drm/xe/tracing: Fix a potential TP_printk UAF

by Thomas Hellström

The commit afd2627f727b ("tracing: Check "%s" dereference via the field and not the TP_printk format") exposes potential UAFs in the xe_bo_move trace event. Fix those by avoiding dereferencing the xe_mem_type_to_name[] array at TP_printk time. Since some code refactoring has taken place, explicit backporting may be needed for kernels older than 6.10.
