2025-06-08tools/power turbostat: Remove add_rapl_perf_counter_()Zhang Rui
As the only caller of add_rapl_perf_counter_(), add_rapl_perf_counter() just gives extra debug output on top. There is no need to keep both functions. Remove add_rapl_perf_counter_() and move all the logic to add_rapl_perf_counter(). No functional change. Signed-off-by: Zhang Rui <rui.zhang@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

2025-06-08tools/power turbostat: Fix AMD package-energy reportingGautham R. Shenoy
commit 05a2f07db888 ("tools/power turbostat: read RAPL counters via perf") that adds support to read RAPL counters via perf defines the notion of a RAPL domain_id which is set to physical_core_id on platforms which support per_core_rapl counters (Eg: AMD processors Family 17h onwards) and is set to the physical_package_id on all the other platforms. However, the physical_core_id is only unique within a package and on platforms with multiple packages more than one core can have the same physical_core_id and thus the same domain_id. (For eg, the first cores of each package have the physical_core_id = 0). This results in all these cores with the same physical_core_id using the same entry in the rapl_counter_info_perdomain[]. Since rapl_perf_init() skips the perf-initialization for cores whose domain_ids have already been visited, cores that have the same physical_core_id always read the perf file corresponding to the physical_core_id of the first package and thus the package-energy is incorrectly reported to be the same value for different packages. Note: This issue only arises when RAPL counters are read via perf and not when they are read via MSRs since in the latter case the MSRs are read separately on each core. Fix this issue by associating each CPU with rapl_core_id which is unique across all the packages in the system.

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull more tracing fixes from Steven Rostedt: - Fix regression of waiting a long time on updating trace event filters When the faultable trace points were added, it needed task trace RCU synchronization. This was added to the tracepoint_synchronize_unregister() function. The filter logic always called this function whenever it updated the trace event filters before freeing the old filters. This increased the time of "trace-cmd record" from taking 13 seconds to running over 2 minutes to complete. Move the freeing of the filters to call_rcu*() logic, which brings the time back down to 13 seconds. - Fix ring_buffer_subbuf_order_set() error path lock protection The error path of the ring_buffer_subbuf_order_set() released the mutex too early and allowed subsequent accesses to setting the subbuffer size to corrupt the data and cause a bug. By moving the mutex locking to the end of the error path, it prevents the reentrant access to the critical data and also allows the function to convert the taking of the mutex over to the guard() logic. - Remove unused power management clock events The clock events were added in 2010 for power management. In 2011 arm used them. In 2013 the code they were used in was removed. These events have been wasting memory since then. - Fix sparse warnings There was a few places that sparse warned about trace_events_filter.c where file->filter was referenced directly, but it is annotated with an __rcu tag. Use the helper functions and fix them up to use rcu_dereference() properly. * tag 'trace-v6.16-3' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: tracing: Add rcu annotation around file->filter accesses tracing: PM: Remove unused clock events ring-buffer: Fix buffer locking in ring_buffer_subbuf_order_set() tracing: Fix regression of filter waiting a long time on RCU synchronization

2025-06-07sh: Replace __ASSEMBLY__ with __ASSEMBLER__ in all headersThomas Huth
While the GCC and Clang compilers already define __ASSEMBLER__ automatically when compiling assembly code, __ASSEMBLY__ is a macro that only gets defined by the Makefiles in the kernel. This can be very confusing when switching between userspace and kernelspace coding, or when dealing with uapi headers that rather should use __ASSEMBLER__ instead. So let's standardize on the __ASSEMBLER__ macro that is provided by the compilers now. This is a completely mechanical patch (done with a simple "sed -i" statement).

Enumeration constants read from a symbol reference file can incorrectly affect new enumeration constants parsed from an actual input file. Example: $ cat test.c enum { E_A, E_B, E_MAX }; struct bar { int mem[E_MAX]; }; int foo(struct bar *a) {} __GENKSYMS_EXPORT_SYMBOL(foo); $ cat test.c | ./scripts/genksyms/genksyms -T test.0.symtypes #SYMVER foo 0x070d854d $ cat test.0.symtypes E#E_MAX 2 s#bar struct bar { int mem [ E#E_MAX ] ; } foo int foo ( s#bar * ) $ cat test.c | ./scripts/genksyms/genksyms -T test.1.symtypes -r test.0.symtypes <stdin>:4: warning: foo: modversion changed because of changes in enum constant E_MAX #SYMVER foo 0x9c9dfd81 $ cat test.1.symtypes E#E_MAX ( 2 ) + 3 s#bar struct bar { int mem [ E#E_MAX ] ; } foo int foo ( s#bar * ) The __add_symbol() function includes logic to handle the incrementation of enumeration values, but this code is also invoked when reading a reference file. As a result, the variables last_enum_expr and enum_counter might be incorrectly set after reading the reference file, which later affects parsing of the actual input. Fix the problem by splitting the logic for the incrementation of enumeration values into a separate function process_enum() and call it from __add_symbol() only when processing non-reference data.

2025-06-07clone_private_mnt(): make sure that caller has CAP_SYS_ADMIN in the right usernsAl Viro
What we want is to verify there is that clone won't expose something hidden by a mount we wouldn't be able to undo. "Wouldn't be able to undo" may be a result of MNT_LOCKED on a child, but it may also come from lacking admin rights in the userns of the namespace mount belongs to. clone_private_mnt() checks the former, but not the latter. There's a number of rather confusing CAP_SYS_ADMIN checks in various userns during the mount, especially with the new mount API; they serve different purposes and in case of clone_private_mnt() they usually, but not always end up covering the missing check mentioned above.

Mounting overlayfs with a directory on real rootfs (initramfs) as upperdir has failed with following message since commit db04662e2f4f ("fs: allow detached mounts in clone_private_mount()"). [ 4.080134] overlayfs: failed to clone upperpath Overlayfs mount uses clone_private_mount() to create internal mount for the underlying layers. The commit made clone_private_mount() reject real rootfs because it does not have a parent mount and is in the initial mount namespace, that is not an anonymous mount namespace. This issue can be fixed by modifying the permission check of clone_private_mount() following [1].

2025-06-07fix propagation graph breakage by MOVE_MOUNT_SET_GROUP move_mount(2)Al Viro
9ffb14ef61ba "move_mount: allow to add a mount into an existing group" breaks assertions on ->mnt_share/->mnt_slave. For once, the data structures in question are actually documented. Documentation/filesystem/sharedsubtree.rst: All vfsmounts in a peer group have the same ->mnt_master. If it is non-NULL, they form a contiguous (ordered) segment of slave list. do_set_group() puts a mount into the same place in propagation graph as the old one. As the result, if old mount gets events from somewhere and is not a pure event sink, new one needs to be placed next to the old one in the slave list the old one's on. If it is a pure event sink, we only need to make sure the new one doesn't end up in the middle of some peer group. "move_mount: allow to add a mount into an existing group" ends up putting the new one in the beginning of list; that's definitely not going to be in the middle of anything, so that's fine for case when old is not marked shared. In case when old one _is_ marked shared (i.e. is not a pure event sink), that breaks the assumptions of propagation graph iterators. Put the new mount next to the old one on the list - that does the right thing in "old is marked shared" case and is just as correct as the current behaviour if old is not marked shared (kudos to Pavel for pointing that out - my original suggested fix changed behaviour in the "nor marked" case, which complicated things for no good reason).

2025-06-07finish_automount(): don't leak MNT_LOCKED from parent to childAl Viro
Intention for MNT_LOCKED had always been to protect the internal mountpoints within a subtree that got copied across the userns boundary, not the mountpoint that tree got attached to - after all, it _was_ exposed before the copying. For roots of secondary copies that is enforced in attach_recursive_mnt() - MNT_LOCKED is explicitly stripped for those. For the root of primary copy we are almost always guaranteed that MNT_LOCKED won't be there, so attach_recursive_mnt() doesn't bother. Unfortunately, one call chain got overlooked - triggering e.g. NFS referral will have the submount inherit the public flags from parent; that's fine for such things as read-only, nosuid, etc., but not for MNT_LOCKED. This is particularly pointless since the mount attached by finish_automount() is usually expirable, which makes any protection granted by MNT_LOCKED null and void; just wait for a while and that mount will go away on its own. Include MNT_LOCKED into the set of flags to be ignored by do_add_mount() - it really is an internal flag.

2025-06-07path_overmount(): avoid false negativesAl Viro
Holding namespace_sem is enough to make sure that result remains valid. It is *not* enough to avoid false negatives from __lookup_mnt(). Mounts can be unhashed outside of namespace_sem (stuck children getting detached on final mntput() of lazy-umounted mount) and having an unrelated mount removed from the hash chain while we traverse it may end up with false negative from __lookup_mnt(). We need to sample and recheck the seqlock component of mount_lock... Bug predates the introduction of path_overmount() - it had come from the code in finish_automount() that got abstracted into that helper.

2025-06-06tracing: Fix regression of filter waiting a long time on RCU synchronizationSteven Rostedt
When faultable trace events were added, a trace event may no longer use normal RCU to synchronize but instead used synchronize_rcu_tasks_trace(). This synchronization takes a much longer time to synchronize. The filter logic would free the filters by calling tracepoint_synchronize_unregister() after it unhooked the filter strings and before freeing them. With this function now calling synchronize_rcu_tasks_trace() this increased the time to free a filter tremendously. On a PREEMPT_RT system, it was even more noticeable. # time trace-cmd record -p function sleep 1 [..] real 2m29.052s user 0m0.244s sys 0m20.136s As trace-cmd would clear out all the filters before recording, it could take up to 2 minutes to do a recording of "sleep 1". To find out where the issues was: ~# trace-cmd sqlhist -e -n sched_stack select start.prev_state as state, end.next_comm as comm, TIMESTAMP_DELTA_USECS as delta, start.STACKTRACE as stack from sched_switch as start join sched_switch as end on start.prev_pid = end.next_pid Which will produce the following commands (and -e will also execute them): echo 's:sched_stack s64 state; char comm[16]; u64 delta; unsigned long stack[];' >> /sys/kernel/tracing/dynamic_events echo 'hist:keys=prev_pid:__arg_18057_2=prev_state,__arg_18057_4=common_timestamp.usecs,__arg_18057_7=common_stacktrace' >> /sys/kernel/tracing/events/sched/sched_switch/trigger echo 'hist:keys=next_pid:__state_18057_1=$__arg_18057_2,__comm_18057_3=next_comm,__delta_18057_5=common_timestamp.usecs-$__arg_18057_4,__stack_18057_6=$__arg_18057_7:onmatch(sched.sched_switch).trace(sched_stack,$__state_18057_1,$__comm_18057_3,$__delta_18057_5,$__stack_18057_6)' >> /sys/kernel/tracing/events/sched/sched_switch/trigger The above creates a synthetic event that creates a stack trace when a task schedules out and records it with the time it scheduled back in. Basically the time a task is off the CPU. It also records the state of the task when it left the CPU (running, blocked, sleeping, etc). It also saves the comm of the task as "comm" (needed for the next command). ~# echo 'hist:keys=state,stack.stacktrace:vals=delta:sort=state,delta if comm == "trace-cmd" && state & 3' > /sys/kernel/tracing/events/synthetic/sched_stack/trigger The above creates a histogram with buckets per state, per stack, and the value of the total time it was off the CPU for that stack trace. It filters on tasks with "comm == trace-cmd" and only the sleeping and blocked states (1 - sleeping, 2 - blocked). ~# trace-cmd record -p function sleep 1 ~# cat /sys/kernel/tracing/events/synthetic/sched_stack/hist | tail -18 { state: 2, stack.stacktrace __schedule+0x1545/0x3700 schedule+0xe2/0x390 schedule_timeout+0x175/0x200 wait_for_completion_state+0x294/0x440 __wait_rcu_gp+0x247/0x4f0 synchronize_rcu_tasks_generic+0x151/0x230 apply_subsystem_event_filter+0xa2b/0x1300 subsystem_filter_write+0x67/0xc0 vfs_write+0x1e2/0xeb0 ksys_write+0xff/0x1d0 do_syscall_64+0x7b/0x420 entry_SYSCALL_64_after_hwframe+0x76/0x7e } hitcount: 237 delta: 99756288 <<--------------- Delta is 99 seconds! Totals: Hits: 525 Entries: 21 Dropped: 0 This shows that this particular trace waited for 99 seconds on synchronize_rcu_tasks() in apply_subsystem_event_filter(). In fact, there's a lot of places in the filter code that spends a lot of time waiting for synchronize_rcu_tasks_trace() in order to free the filters. Add helper functions that will use call_rcu*() variants to asynchronously free the filters. This brings the timings back to normal: # time trace-cmd record -p function sleep 1 [..] real 0m14.681s user 0m0.335s sys 0m28.616s And the histogram also shows this: ~# cat /sys/kernel/tracing/events/synthetic/sched_stack/hist | tail -21 { state: 2, stack.stacktrace __schedule+0x1545/0x3700 schedule+0xe2/0x390 schedule_timeout+0x175/0x200 wait_for_completion_state+0x294/0x440 __wait_rcu_gp+0x247/0x4f0 synchronize_rcu_normal+0x3db/0x5c0 tracing_reset_online_cpus+0x8f/0x1e0 tracing_open+0x335/0x440 do_dentry_open+0x4c6/0x17a0 vfs_open+0x82/0x360 path_openat+0x1a36/0x2990 do_filp_open+0x1c5/0x420 do_sys_openat2+0xed/0x180 __x64_sys_openat+0x108/0x1d0 do_syscall_64+0x7b/0x420 } hitcount: 2 delta: 77044 Totals: Hits: 55 Entries: 28 Dropped: 0 Where the total waiting time of synchronize_rcu_tasks_trace() is 77 milliseconds.
