sched_ext: Changes for v6.15
- Add mechanism to count and report internal events. This significantly improves visibility on subtle corner conditions. - The default idle CPU selection logic is revamped and improved in multiple ways including being made topology aware. - sched_ext was disabling ttwu_queue for simplicity, which can be costly when hardware topology is more complex. Implement SCX_OPS_ALLOWED_QUEUED_WAKEUP so that BPF schedulers can selectively enable ttwu_queue. - tools/sched_ext updates to improve compatibility among others. - Other misc updates and fixes. - sched_ext/for-6.14-fixes were pulled a few times to receive prerequisite fixes and resolve conflicts. -----BEGIN PGP SIGNATURE----- iIQEABYKACwWIQTfIjM1kS57o3GsC/uxYfJx3gVYGQUCZ999Sg4cdGpAa2VybmVs Lm9yZwAKCRCxYfJx3gVYGf/KAQCoMTVOBpQT9gCaCKDOmrVJTwi6boEoV5WnGZzw PDr0vwEAq36iz4no6Y5THcN/DCx+52IiS0zuhPy3rBZVo11TMgU= =iQ+A -----END PGP SIGNATURE----- Merge tag 'sched_ext-for-6.15' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/sched_ext Pull sched_ext updates from Tejun Heo: - Add mechanism to count and report internal events.

Refactor the #ifdef guards so that the simple implementation is also used with SLUB_TINY.

Thanks to moving the kvmalloc() implementation to slub.c, this is improved and randomization now works for kvmalloc. - Various improvements to debugging, testing and other cleanups (Hyesoo Yu, Lilith Gkini, Uladzislau Rezki, Matthew Wilcox, Kevin Brodsky, Ye Bin) * tag 'slab-for-6.15' of git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab: slub: Handle freelist cycle in on_freelist() mm/slab: call kmalloc_noprof() unconditionally in kmalloc_array_noprof() slab: Mark large folios for debugging purposes kunit, slub: Add test_kfree_rcu_wq_destroy use case mm, slab: cleanup slab_bug() parameters mm: slub: call WARN() when detecting a slab corruption mm: slub: Print the broken data before restoring them slab: Achieve better kmalloc caches randomization in kvmalloc slab: Adjust placement of __kvmalloc_node_noprof mm/slab: simplify SLAB_* flag handling slab: don't batch kvfree_rcu() with SLUB_TINY rcu, slab: use a regular callback function for kvfree_rcu rcu: remove trace_rcu_kvfree_callback slab, rcu: move TINY_RCU variant of kvfree_rcu() to SLAB |

Pull vfs file handling updates from Christian Brauner:
"This contains performance improvements for struct file's new refcount
mechanism and various other performance work:
- The stock kernel transitioning the file to no refs held penalizes
the caller with an extra atomic to block any increments. For cases
where the file is highly likely to be going away this is easily
avoidable.
Add file_ref_put_close() to better handle the common case where
closing a file descriptor also operates on the last reference and
build fput_close_sync() and fput_close() on top of it. This brings
about 1% performance improvement by eliding one atomic in the
common case.
- Predict no error in close() since the vast majority of the time
system call returns 0.
- Reduce the work done in fdget_pos() by predicting that the file was
found and by explicitly comparing the reference count to one and
ignoring the dead zone"

Pull vfs afs updates from Christian Brauner:
"This contains the work for afs for this cycle:
- Fix an occasional hang that's only really encountered when
rmmod'ing the kafs module
- Remove the "-o autocell" mount option. This is obsolete with the
dynamic root and removing it makes the next patch slightly easier
- Change how the dynamic root mount is constructed. Currently, the
root directory is (de)populated when it is (un)mounted if there are
cells already configured and, further, pairs of automount points
have to be created/removed each time a cell is added/deleted
This is changed so that readdir on the root dir lists all the known
cell automount pairs plus the @cell symlinks and the inodes and
dentries are constructed by lookup on demand. This simplifies the
cell management code
- A few improvements to the afs_volume and afs_server tracepoints
- Pass trace info into the afs_lookup_cell() function to allow the
trace log to indicate the purpose of the lookup
- Remove the 'net' parameter from afs_unuse_cell() as it's
superfluous
- In rxrpc, allow a kernel app (such as kafs) to store a word of
information on rxrpc_peer records
- Use the information stored on the rxrpc_peer record to point to the
afs_server record. This allows the server address lookup to be done
away with
- Simplify the afs_server ref/activity accounting to make each one
self-contained and not garbage collected from the cell management
work item
- Simplify the afs_cell ref/activity accounting to make each one of
these also self-contained and not driven by a central management
work item
The current code was intended to make it such that a single timer
for the namespace and one work item per cell could do all the work
required to maintain these records. This, however, made for some
sequencing problems when cleaning up these records. Further, the
attempt to pass refs along with timers and work items made getting
it right rather tricky when the timer or work item already had a
ref attached and now a ref had to be got rid of"

Pull vfs mount namespace updates from Christian Brauner:
"This expands the ability of anonymous mount namespaces:
- Creating detached mounts from detached mounts
Currently, detached mounts can only be created from attached
mounts. This limitaton prevents various use-cases. For example, the
ability to mount a subdirectory without ever having to make the
whole filesystem visible first.
The current permission modelis:
(1) Check that the caller is privileged over the owning user
namespace of it's current mount namespace.
(2) Check that the caller is located in the mount namespace of the
mount it wants to create a detached copy of.
While it is not strictly necessary to do it this way it is
consistently applied in the new mount api. This model will also be
used when allowing the creation of detached mount from another
detached mount.
The (1) requirement can simply be met by performing the same check
as for the non-detached case, i.e., verify that the caller is
privileged over its current mount namespace.
To meet the (2) requirement it must be possible to infer the origin
mount namespace that the anonymous mount namespace of the detached
mount was created from.
The origin mount namespace of an anonymous mount is the mount
namespace that the mounts that were copied into the anonymous mount
namespace originate from.
In order to check the origin mount namespace of an anonymous mount
namespace the sequence number of the original mount namespace is
recorded in the anonymous mount namespace.
With this in place it is possible to perform an equivalent check
(2') to (2). The origin mount namespace of the anonymous mount
namespace must be the same as the caller's mount namespace. To
establish this the sequence number of the caller's mount namespace
and the origin sequence number of the anonymous mount namespace are
compared.
The caller is always located in a non-anonymous mount namespace
since anonymous mount namespaces cannot be setns()ed into. The
caller's mount namespace will thus always have a valid sequence
number.
The owning namespace of any mount namespace, anonymous or
non-anonymous, can never change. A mount attached to a
non-anonymous mount namespace can never change mount namespace.
If the sequence number of the non-anonymous mount namespace and the
origin sequence number of the anonymous mount namespace match, the
owning namespaces must match as well.
Hence, the capability check on the owning namespace of the caller's
mount namespace ensures that the caller has the ability to copy the
mount tree.
- Allow mount detached mounts on detached mounts
Currently, detached mounts can only be mounted onto attached
mounts. This limitation makes it impossible to assemble a new
private rootfs and move it into place. Instead, a detached tree
must be created, attached, then mounted open and then either moved
or detached again. Lift this restriction.
In order to allow mounting detached mounts onto other detached
mounts the same permission model used for creating detached mounts
from detached mounts can be used (cf. above).
Allowing to mount detached mounts onto detached mounts leaves three
cases to consider:
(1) The source mount is an attached mount and the target mount is
a detached mount. This would be equivalent to moving a mount
between different mount namespaces. A caller could move an
attached mount to a detached mount. The detached mount can now
be freely attached to any mount namespace. This changes the
current delegatioh model significantly for no good reason. So
this will fail.
(2) Anonymous mount namespaces are always attached fully, i.e., it
is not possible to only attach a subtree of an anoymous mount
namespace. This simplifies the implementation and reasoning.
Consequently, if the anonymous mount namespace of the source
detached mount and the target detached mount are the identical
the mount request will fail.
(3) The source mount's anonymous mount namespace is different from
the target mount's anonymous mount namespace.
In this case the source anonymous mount namespace of the
source mount tree must be freed after its mounts have been
moved to the target anonymous mount namespace. The source
anonymous mount namespace must be empty afterwards.
By allowing to mount detached mounts onto detached mounts a caller
may do the following:
fd_tree1 = open_tree(-EBADF, "/mnt", OPEN_TREE_CLONE)
fd_tree2 = open_tree(-EBADF, "/tmp", OPEN_TREE_CLONE)
fd_tree1 and fd_tree2 refer to two different detached mount trees
that belong to two different anonymous mount namespace.
It is important to note that fd_tree1 and fd_tree2 both refer to
the root of their respective anonymous mount namespaces.
By allowing to mount detached mounts onto detached mounts the
caller may now do:
move_mount(fd_tree1, "", fd_tree2, "",
MOVE_MOUNT_F_EMPTY_PATH | MOVE_MOUNT_T_EMPTY_PATH)
This will cause the detached mount referred to by fd_tree1 to be
mounted on top of the detached mount referred to by fd_tree2.
Thus, the detached mount fd_tree1 is moved from its separate
anonymous mount namespace into fd_tree2's anonymous mount
namespace.
It also means that while fd_tree2 continues to refer to the root of
its respective anonymous mount namespace fd_tree1 doesn't anymore.
This has the consequence that only fd_tree2 can be moved to another
anonymous or non-anonymous mount namespace. Moving fd_tree1 will
now fail as fd_tree1 doesn't refer to the root of an anoymous mount
namespace anymore.
Now fd_tree1 and fd_tree2 refer to separate detached mount trees
referring to the same anonymous mount namespace.
This is conceptually fine. The new mount api does allow for this to
happen already via:
mount -t tmpfs tmpfs /mnt
mkdir -p /mnt/A
mount -t tmpfs tmpfs /mnt/A
fd_tree3 = open_tree(-EBADF, "/mnt", OPEN_TREE_CLONE | AT_RECURSIVE)
fd_tree4 = open_tree(-EBADF, "/mnt/A", 0)
Both fd_tree3 and fd_tree4 refer to two different detached mount
trees but both detached mount trees refer to the same anonymous
mount namespace. An as with fd_tree1 and fd_tree2, only fd_tree3
may be moved another mount namespace as fd_tree3 refers to the root
of the anonymous mount namespace just while fd_tree4 doesn't.
However, there's an important difference between the
fd_tree3/fd_tree4 and the fd_tree1/fd_tree2 example.
Closing fd_tree4 and releasing the respective struct file will have
no further effect on fd_tree3's detached mount tree.
However, closing fd_tree3 will cause the mount tree and the
respective anonymous mount namespace to be destroyed causing the
detached mount tree of fd_tree4 to be invalid for further mounting.
By allowing to mount detached mounts on detached mounts as in the
fd_tree1/fd_tree2 example both struct files will affect each other.
Both fd_tree1 and fd_tree2 refer to struct files that have
FMODE_NEED_UNMOUNT set.
To handle this we use the fact that @fd_tree1 will have a parent
mount once it has been attached to @fd_tree2.
When dissolve_on_fput() is called the mount that has been passed in
will refer to the root of the anonymous mount namespace. If it
doesn't it would mean that mounts are leaked. So before allowing to
mount detached mounts onto detached mounts this would be a bug.
Now that detached mounts can be mounted onto detached mounts it
just means that the mount has been attached to another anonymous
mount namespace and thus dissolve_on_fput() must not unmount the
mount tree or free the anonymous mount namespace as the file
referring to the root of the namespace hasn't been closed yet.
If it had been closed yet it would be obvious because the mount
namespace would be NULL, i.e., the @fd_tree1 would have already
been unmounted. If @fd_tree1 hasn't been unmounted yet and has a
parent mount it is safe to skip any cleanup as closing @fd_tree2
will take care of all cleanup operations.

Pull vfs pidfs updates from Christian Brauner:
- Allow retrieving exit information after a process has been reaped
through pidfds via the new PIDFD_INTO_EXIT extension for the
PIDFD_GET_INFO ioctl. Various tools need access to information about
a process/task even after it has already been reaped.
Pidfd polling allows waiting on either task exit or for a task to
have been reaped. The contract for PIDFD_INFO_EXIT is simply that
EPOLLHUP must be observed before exit information can be retrieved,
i.e., exit information is only provided once the task has been reaped
and then can be retrieved as long as the pidfd is open.
- Add PIDFD_SELF_{THREAD,THREAD_GROUP} sentinels allowing userspace to
forgo allocating a file descriptor for their own process. This is
useful in scenarios where users want to act on their own process
through pidfds and is akin to AT_FDCWD.
- Improve premature thread-group leader and subthread exec behavior
when polling on pidfds:
(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 is 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.
After this pull no exit notifications will be 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.
This means an exit notification indicates the ability for the father
to reap the child.

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

keys: Fix UAF in key_put()
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.

perf/amd/ibs: Prevent leaking sensitive data to userspace
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:
