Pull vfs mount updates from Christian Brauner:
- Mount notifications
The day has come where we finally provide a new api to listen for
mount topology changes outside of /proc/<pid>/mountinfo. A mount
namespace file descriptor can be supplied and registered with
fanotify to listen for mount topology changes.
Currently notifications for mount, umount and moving mounts are
generated. The generated notification record contains the unique
mount id of the mount.
The listmount() and statmount() api can be used to query detailed
information about the mount using the received unique mount id.
This allows userspace to figure out exactly how the mount topology
changed without having to generating diffs of /proc/<pid>/mountinfo
in userspace.
- Support O_PATH file descriptors with FSCONFIG_SET_FD in the new mount
api
- Support detached mounts in overlayfs
Since last cycle we support specifying overlayfs layers via file
descriptors. However, we don't allow detached mounts which means
userspace cannot user file descriptors received via
open_tree(OPEN_TREE_CLONE) and fsmount() directly. They have to
attach them to a mount namespace via move_mount() first.
This is cumbersome and means they have to undo mounts via umount().
Allow them to directly use detached mounts.
- Allow to retrieve idmappings with statmount
Currently it isn't possible to figure out what idmapping has been
attached to an idmapped mount. Add an extension to statmount() which
allows to read the idmapping from the mount.
- Allow creating idmapped mounts from mounts that are already idmapped
So far it isn't possible to allow the creation of idmapped mounts
from already idmapped mounts as this has significant lifetime
implications. Make the creation of idmapped mounts atomic by allow to
pass struct mount_attr together with the open_tree_attr() system call
allowing to solve these issues without complicating VFS lookup in any
way.
The system call has in general the benefit that creating a detached
mount and applying mount attributes to it becomes an atomic operation
for userspace.
- Add a way to query statmount() for supported options
Allow userspace to query which mount information can be retrieved
through statmount().
- Allow superblock owners to force unmount

REQ_F_NEED_CLEANUP, so after the following snippet the request will
never hit the core io_uring cleanup path.

Once a key's reference count has been reduced to 0, the garbage collector
thread may destroy it at any time and so key_put() is not allowed to touch
the key after that point. The most key_put() is normally allowed to do is
to touch key_gc_work as that's a static global variable.
However, in an effort to speed up the reclamation of quota, this is now
done in key_put() once the key's usage is reduced to 0 - but now the code
is looking at the key after the deadline, which is forbidden.
Fix this by using a flag to indicate that a key can be gc'd now rather than
looking at the key's refcount in the garbage collector.

CONFIG_TRACE_BRANCH_PROFILING inserts a call to ftrace_likely_update()
for each use of likely() or unlikely(). That breaks noinstr rules if
the affected function is annotated as noinstr.
Disable branch profiling for files with noinstr functions. In addition
to some individual files, this also includes the entire arch/x86
subtree, as well as the kernel/entry, drivers/cpuidle, and drivers/idle
directories, all of which are noinstr-heavy.
Due to the nature of how sched binaries are built by combining multiple
.c files into one, branch profiling is disabled more broadly across the
sched code than would otherwise be needed.
This fixes many warnings like the following:
vmlinux.o: warning: objtool: do_syscall_64+0x40: call to ftrace_likely_update() leaves .noinstr.text section
vmlinux.o: warning: objtool: __rdgsbase_inactive+0x33: call to ftrace_likely_update() leaves .noinstr.text section

Although IBS "swfilt" can prevent leaking samples with kernel RIP to the
userspace, there are few subtle cases where a 'data' address and/or a
'branch target' address can fall under kernel address range although RIP
is from userspace. Prevent leaking kernel 'data' addresses by discarding
such samples when {exclude_kernel=1,swfilt=1}.
IBS can now be invoked by unprivileged user with the introduction of
"swfilt". However, this creates a loophole in the interface where an
unprivileged user can get physical address of the userspace virtual
addresses through IBS register raw dump (PERF_SAMPLE_RAW). Prevent this
as well.
This upstream commit fixed the most obvious leak:
65a99264f5e5 perf/x86: Check data address for IBS software filter
Follow that up with a more complete fix.

Clang does not tolerate the use of non-TLS symbols for the per-CPU stack
protector very well, and to work around this limitation, the symbol
passed via the -mstack-protector-guard-symbol= option is never defined
in C code, but only in the linker script, and it is exported from an
assembly file. This is necessary because Clang will fail to generate the
correct %GS based references in a compilation unit that includes a
non-TLS definition of the guard symbol being used to store the stack
cookie.
This problem is only triggered by symbol definitions, not by
declarations, but nonetheless, the declaration in <asm/asm-prototypes.h>
is conditional on __GENKSYMS__ being #define'd, so that only genksyms
will observe it, but for ordinary compilation, it will be invisible.
This is causing problems with the genksyms alternative gendwarfksyms,
which does not #define __GENKSYMS__, does not observe the symbol
declaration, and therefore lacks the information it needs to version it.
Adding the #define creates problems in other places, so that is not a
straight-forward solution. So take the easy way out, and drop the
conditional on __GENKSYMS__, as this is not really needed to begin with.

Now that the rstat lock is being re-acquired on every CPU iteration in
cgroup_rstat_flush_locked(), having the initially acquire the lock is
unnecessary and unclear.
Inline cgroup_rstat_flush_locked() into cgroup_rstat_flush() and move
the lock/unlock calls to the beginning and ending of the loop body to
make the critical section obvious.
cgroup_rstat_flush_hold/release() do not make much sense with the lock
being dropped and reacquired internally. Since it has no external
callers, remove it and explicitly acquire the lock in
cgroup_base_stat_cputime_show() instead.
This leaves the code with a single flushing function,
cgroup_rstat_flush().

Following Paolo's suggestion, let's revert the IPv6 link-local address

Start by reverting the kselftest that depend on that fix (patch 1), then
revert the kernel code itself (patch 2).

thread-group leader exit"
Christian Brauner <brauner@kernel.org> says:
This is another attempt at trying to make pidfd polling for
multi-threaded exec and premature thread-group leader exit consistent.
A quick recap of these two cases:
(1) During a multi-threaded exec by a subthread, i.e., non-thread-group
leader thread, all other threads in the thread-group including the
thread-group leader are killed and the struct pid of the
thread-group leader will be taken over by the subthread that called
exec. IOW, two tasks change their TIDs.
(2) A premature thread-group leader exit means that the thread-group
leader exited before all of the other subthreads in the thread-group
have exited.
Both cases lead to inconsistencies for pidfd polling with PIDFD_THREAD.
Any caller that holds a PIDFD_THREAD pidfd to the current thread-group
leader may or may not see an exit notification on the file descriptor
depending on when poll is performed. If the poll is performed before the
exec of the subthread has concluded an exit notification is generated
for the old thread-group leader. If the poll is performed after the exec
of the subthread has concluded no exit notification is generated for the
old thread-group leader.
The correct behavior would be to simply not generate an exit
notification on the struct pid of a subhthread exec because the struct
pid is taken over by the subthread and thus remains alive.
But this is difficult to handle because a thread-group may exit
premature as mentioned in (2). In that case an exit notification is
reliably generated but the subthreads may continue to run for an
indeterminate amount of time and thus also may exec at some point.
This tiny series tries to address this problem. If that works correctly
then no exit notifications are generated for a PIDFD_THREAD pidfd for a
thread-group leader until all subthreads have been reaped. If a
subthread should exec before no exit notification will be generated
until that task exits or it creates subthreads and repeates the cycle.
