Pull x86 perf fix from Thomas Gleixner:
"A single fix for the x86 performance counters on Intel CPUs:
The MSR offset calculations for fixed performance counters are stored
at the wrong index in the configuration array causing the general
purpose counter MSR offset to be overwritten, so both the general
purpose and the fixed counters offsets are incorrect.
Correct the array index calculation to fix that"

Pull irq fix from Thomas Gleixner:
"A single fix for the PCI/MSI code:
The conversion to per device MSI domains created a MSI domain with
size 1 instead of sizing it to the maximum possible number of MSI
interrupts for the device. This "worked" as the subsequent allocations
resized the domain, but the recent change to move the prepare() call
into the domain creation path broke this works by chance mechanism.
Size the domain properly at creation time"

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.

unregistered properly. Its memory is freed after rmmod, which may trigger
to a use-after-free (UAF) issue if there is a subsequent access to this

Currently to get firmware stats, ath11k_mac_op_get_txpower() calls
ath11k_fw_stats_request() and ath11k_mac_op_sta_statistics() calls
ath11k_mac_get_fw_stats(). Those two helpers are basically doing
the same, except for:
1. ath11k_mac_get_fw_stats() verifies ar->state inside itself.
2. ath11k_mac_get_fw_stats() calls ath11k_mac_fw_stats_request()
which then calls ath11k_mac_fw_stats_reset() to free pdev/vdev
stats whereas only pdev stats are freed by ath11k_fw_stats_request().
3. ath11k_mac_get_fw_stats() waits for ar->fw_stats_complete and
ar->fw_stats_done, whereas ath11k_fw_stats_request() only waits for
ar->fw_stats_complete.
Change to call ath11k_mac_get_fw_stats() in ath11k_mac_op_get_txpower().
This is valid because:
1. ath11k_mac_op_get_txpower() also has the same request on ar->state.
2. it is harmless to call ath11k_fw_stats_vdevs_free() since
ar->fw_stats.vdevs should be empty and there should be no one
expecting it at that time.
3. ath11k_mac_op_get_txpower() only needs pdev stats. For pdev stats,
ar->fw_stats_done is set to true whenever ar->fw_stats_complete is
set to true in ath11k_update_stats_event(). So additional wait on
ar->fw_stats_done does not wast any time.

Currently ath11k_mac_get_fw_stats() is acquiring/releasing ar->conf_mutex by itself.
In order to reuse this function in a context where that lock is already taken, move
lock handling to its callers, then the function itself only has to assert it.
There is only one caller now, i.e., ath11k_mac_op_sta_statistics(), so add lock handling
there.

For WMI_REQUEST_VDEV_STAT request, firmware might split response into
multiple events dut to buffer limit, hence currently in
ath11k_debugfs_fw_stats_process() we wait until all events received.
In case there is no vdev started, this results in that below condition
would never get satisfied
((++ar->fw_stats.num_vdev_recvd) == total_vdevs_started)
finally the requestor would be blocked until wait time out.
The same applies to WMI_REQUEST_BCN_STAT request as well due to:
((++ar->fw_stats.num_bcn_recvd) == ar->num_started_vdevs)
Change to check the number of started vdev first: if it is zero, finish
wait directly; if not, follow the old way.

Currently ath11k_debugfs_fw_stats_process() is using static variables to count
firmware stat events. Taking num_vdev as an example, if for whatever reason (
say ar->num_started_vdevs is 0 or firmware bug etc.) the following condition
(++num_vdev) == total_vdevs_started
is not met, is_end is not set thus num_vdev won't be cleared. Next time when
firmware stats is requested again, even if everything is working fine, we will
fail due to the condition above will never be satisfied.
The same applies to num_bcn as well.
Change to use non-static counters so that we have a chance to clear them each
time firmware stats is requested. Currently only ath11k_fw_stats_request() and
ath11k_debugfs_fw_stats_request() are requesting firmware stats, so clear
counters there.

In some scenarios, the firmware may be stopped before the interface is
removed, either due to a crash or because the remoteproc (e.g., MPSS)
is shut down early during system reboot or shutdown.
This leads to a delay during interface teardown, as the driver waits for
a vdev delete response that never arrives, eventually timing out.
Example (SNOC):
$ echo stop > /sys/class/remoteproc/remoteproc0/state
[ 71.64] remoteproc remoteproc0: stopped remote processor modem
$ reboot
[ 74.84] ath10k_snoc c800000.wifi: failed to transmit packet, dropping: -108
[ 74.84] ath10k_snoc c800000.wifi: failed to submit frame: -108
[...]
[ 82.39] ath10k_snoc c800000.wifi: Timeout in receiving vdev delete response
To avoid this, skip waiting for the vdev delete response if the firmware is
already marked as unreachable (`ATH10K_FLAG_CRASH_FLUSH`), similar to how
`ath10k_mac_wait_tx_complete()` and `ath10k_vdev_setup_sync()` handle this case.

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.

KBUILD_BUILTIN is set to 1 unless you are building only modules.
KBUILD_MODULES is set to 1 when you are building only modules
(a typical use case is "make modules").
It is more useful to set them to 'y' instead, so we can do
something like:
always-$(KBUILD_BUILTIN) += vmlinux.lds
This works equivalently to:
extra-y += vmlinux.lds
This allows us to deprecate extra-y. extra-y and always-y are quite

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.

... and fix the breakage in anon-to-anon case. There are two cases
acceptable for do_move_mount() and mixing checks for those is making
things hard to follow.
One case is move of a subtree in caller's namespace.
* source and destination must be in caller's namespace
* source must be detachable from parent
Another is moving the entire anon namespace elsewhere
* source must be the root of anon namespace
* target must either in caller's namespace or in a suitable
anon namespace (see may_use_mount() for details).
* target must not be in the same namespace as source.
It's really easier to follow if tests are *not* mixed together...

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].

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).

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.

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.

may_decode_fh() is calling has_locked_children() while holding no locks.

Rename the current has_locked_children() to __has_locked_children(), make
it static and switch the fs/namespace.c users to it.
