The recent move of the bdev_statx call to the low-level vfs_getattr_nosec
helper caused it being used by devtmpfs, which leads to deadlocks in
md teardown due to the block device lookup and put interfering with the
unusual lifetime rules in md.
But as handle_remove only works on inodes created and owned by devtmpfs
itself there is no need to use vfs_getattr_nosec vs simply reading the
mode from the inode directly. Switch to that to avoid the bdev lookup
or any other unintentional side effect.

Normally do_lock_mount(path, _) is locking a mountpoint pinned by
*path and at the time when matching unlock_mount() unlocks that
location it is still pinned by the same thing.
Unfortunately, for 'beneath' case it's no longer that simple -
the object being locked is not the one *path points to. It's the
mountpoint of path->mnt. The thing is, without sufficient locking
->mnt_parent may change under us and none of the locks are held
at that point. The rules are
* mount_lock stabilizes m->mnt_parent for any mount m.
* namespace_sem stabilizes m->mnt_parent, provided that
m is mounted.
* if either of the above holds and refcount of m is positive,
we are guaranteed the same for refcount of m->mnt_parent.
namespace_sem nests inside inode_lock(), so do_lock_mount() has
to take inode_lock() before grabbing namespace_sem. It does
recheck that path->mnt is still mounted in the same place after
getting namespace_sem, and it does take care to pin the dentry.
It is needed, since otherwise we might end up with racing mount --move
(or umount) happening while we were getting locks; in that case
dentry would no longer be a mountpoint and could've been evicted
on memory pressure along with its inode - not something you want
when grabbing lock on that inode.
However, pinning a dentry is not enough - the matching mount is
also pinned only by the fact that path->mnt is mounted on top it
and at that point we are not holding any locks whatsoever, so
the same kind of races could end up with all references to
that mount gone just as we are about to enter inode_lock().
If that happens, we are left with filesystem being shut down while
we are holding a dentry reference on it; results are not pretty.
What we need to do is grab both dentry and mount at the same time;
that makes inode_lock() safe *and* avoids the problem with fs getting
shut down under us. After taking namespace_sem we verify that
path->mnt is still mounted (which stabilizes its ->mnt_parent) and
check that it's still mounted at the same place. From that point
on to the matching namespace_unlock() we are guaranteed that
mount/dentry pair we'd grabbed are also pinned by being the mountpoint
of path->mnt, so we can quietly drop both the dentry reference (as
the current code does) and mnt one - it's OK to do under namespace_sem,
since we are not dropping the final refs.
That solves the problem on do_lock_mount() side; unlock_mount()
also has one, since dentry is guaranteed to stay pinned only until
the namespace_unlock(). That's easy to fix - just have inode_unlock()
done earlier, while it's still pinned by mp->m_dentry.

This is a respin of the series[0] to address the sleep in atomic
scenarios for noref migration with large folios, introduced in:
3c20917120 ("block/bdev: enable large folio support for large logical block sizes")
The main difference is that it removes the first patch and moves the fix
(reducing the i_private_lock critical region in the migration path) to
the final patch, which also introduces the new BH_Migrate flag. It also
simplifies the locking scheme in patch 1 to avoid folio trylocking in
the atomic lookup cases. So essentially blocking users will take the
folio lock and hence wait for migration, and otherwise nonblocking
callers will bail the lookup if a noref migration is on-going. Blocking
callers will also benefit from potential performance gains by reducing
contention on the spinlock for bdev mappings.

The large folio + buffer head noref migration scenarios are
being naughty and blocking while holding a spinlock.
As a consequence of the pagecache lookup path taking the
folio lock this serializes against migration paths, so
they can wait for each other. For the private_lock
atomic case, a new BH_Migrate flag is introduced which
enables the lookup to bail.
This allows the critical region of the private_lock on
the migration path to be reduced to the way it was before
ebdf4de564 ("mm: migrate: fix reference check race
between __find_get_block() and migration"), that is covering
the count checks.
The scope is always noref migration.

Per the "hack idea", the latter can alleviate contention on

I had left the warning around but as a non-fatal error to get my gcc-15
builds going, but fixed up some of the most annoying warning cases so
that it wouldn't be *too* verbose.
Because I like the _concept_ of the warning, even if I detested the
implementation to shut it up.
It turns out the implementation to shut it up is even more broken than I
thought, and my "shut up most of the warnings" patch just caused fatal
errors on gcc-14 instead.
I had tested with clang, but when I upgrade my development environment,
I try to do it on all machines because I hate having different systems
to maintain, and hadn't realized that gcc-14 now had issues.
The ACPI case is literally why I wanted to have a *type* that doesn't
trigger the warning (see commit d5d45a7f2619: "gcc-15: make
'unterminated string initialization' just a warning"), instead of
marking individual places as "__nonstring".
But gcc-14 doesn't like that __nonstring location that shut gcc-15 up,
because it's on an array of char arrays, not on one single array:
drivers/acpi/tables.c:399:1: error: 'nonstring' attribute ignored on objects of type 'const char[][4]' [-Werror=attributes]
399 | static const char table_sigs[][ACPI_NAMESEG_SIZE] __initconst __nonstring = {
| ^~~~~~
and my attempts to nest it properly with a type had failed, because of
how gcc doesn't like marking the types as having attributes, only
symbols.
There may be some trick to it, but I was already annoyed by the bad
attribute design, now I'm just entirely fed up with it.
I wish gcc had a proper way to say "this type is a *byte* array, not a
string".
The obvious thing would be to distinguish between "char []" and an
explicitly signed "unsigned char []" (as opposed to an implicitly
unsigned char, which is typically an architecture-specific default, but
for the kernel is universal thanks to '-funsigned-char').
But any "we can typedef a 8-bit type to not become a string just because
it's an array" model would be fine.
But "__attribute__((nonstring))" is sadly not that sane model.

The C sequence points are complicated things, and gcc-15 has apparently
added a warning for the case where an object is both used and modified
multiple times within the same sequence point.
That's a great warning.
Or rather, it would be a great warning, except gcc-15 seems to not
really be very exact about it, and doesn't notice that the modification
are to two entirely different members of the same object: the array
counter and the array entries.
So that seems kind of silly.
That said, the code that gcc complains about is unnecessarily
complicated, so moving the array counter update into a separate
statement seems like the most straightforward fix for these warnings:
drivers/net/wireless/intel/iwlwifi/mld/d3.c: In function ‘iwl_mld_set_netdetect_info’:
drivers/net/wireless/intel/iwlwifi/mld/d3.c:1102:66: error: operation on ‘netdetect_info->n_matches’ may be undefined [-Werror=sequence-point]
1102 | netdetect_info->matches[netdetect_info->n_matches++] = match;
| ~~~~~~~~~~~~~~~~~~~~~~~~~^~
drivers/net/wireless/intel/iwlwifi/mld/d3.c:1120:58: error: operation on ‘match->n_channels’ may be undefined [-Werror=sequence-point]
1120 | match->channels[match->n_channels++] =
| ~~~~~~~~~~~~~~~~~^~
side note: the code at that second warning is actively buggy, and only
works on little-endian machines that don't do strict alignment checks.
The code casts an array of integers into an array of unsigned long in
order to use our bitmap iterators. That happens to work fine on any
sane architecture, but it's still wrong.
This does *not* fix that more serious problem. This only splits the two
assignments into two statements and fixes the compiler warning. I need
to get rid of the new warnings in order to be able to actually do any
build testing.

All of these cases are perfectly valid and good traditional C, but hit
by the "you're not NUL-terminating your byte array" warning.
And none of the cases want any terminating NUL character.
Mark them __nonstring to shut up gcc-15 (and in the case of the ak8974
magnetometer driver, I just removed the explicit array size and let gcc
expand the 3-byte and 6-byte arrays by one extra byte, because it was
the simpler change).
Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
This removes two cases of explicit NUL padding that now causes warnings
because of '-Wunterminated-string-initialization' being part of -Wextra
in gcc-15.
Gcc is being silly in this case when it says that it truncates a NUL
terminator, because in these cases there were _multiple_ NUL characters.
But we can get rid of the warning by just simplifying the two
initializers that trigger the warning for me, so this does exactly that.
I'm not sure why the power supply code did that odd
.attr_name = #_name "\0",
pattern: it was introduced in commit 2cabeaf151 ("power: supply: core:
Cleanup power supply sysfs attribute list"), but that 'attr_name[]'
field is an explicitly sized character array in a statically initialized
variable, and a string initializer always has a terminating NUL _and_
statically initialized character arrays are zero-padded anyway, so it
really seems to be rather extraneous belt-and-suspenders.
The zero_uuid[16] initialization in drivers/md/bcache/super.c makes
perfect sense, but it isn't necessary for the same reasons, and not
worth the new gcc warning noise.
Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
This is not great: I'd much rather introduce a typedef that is a "ACPI
name byte buffer", and use that to mark these special 4-byte ACPI names
that do not use NUL termination.
But as noted in the previous commit ("gcc-15: make 'unterminated string
initialization' just a warning") gcc doesn't actually seem to support
that notion, so instead you have to just mark every single array
declaration individually.
So this is not pretty, but this gets rid of the bulk of the annoying
warnings during an allmodconfig build for me.
Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
gcc-15 enabling -Wunterminated-string-initialization in -Wextra by
default was done with the best intentions, but the warning is still
quite broken.
What annoys me about the warning is that this is a very traditional AND
CORRECT way to initialize fixed byte arrays in C:
unsigned char hex[16] = "0123456789abcdef";
and we use this all over the kernel. And the warning is fine, but gcc
developers apparently never made a reasonable way to disable it. As is
(sadly) tradition with these things.
Yes, there's "__attribute__((nonstring))", and we have a macro to make
that absolutely disgusting syntax more palatable (ie the kernel syntax
for that monstrosity is just "__nonstring").
But that attribute is misdesigned. What you'd typically want to do is
tell the compiler that you are using a type that isn't a string but a
byte array, but that doesn't work at all:
warning: ‘nonstring’ attribute does not apply to types [-Wattributes]
and because of this fundamental mis-design, you then have to mark each
instance of that pattern.
This is particularly noticeable in our ACPI code, because ACPI has this
notion of a 4-byte "type name" that gets used all over, and is exactly
this kind of byte array.
This is a sad oversight, because the warning is useful, but really would
be so much better if gcc had also given a sane way to indicate that we
really just want a byte array type at a type level, not the broken "each
and every array definition" level.
So now instead of creating a nice "ACPI name" type using something like
typedef char acpi_name_t[4] __nonstring;
we have to do things like
char name[ACPI_NAMESEG_SIZE] __nonstring;
in every place that uses this concept and then happens to have the
typical initializers.
This is annoying me mainly because I think the warning _is_ a good
warning, which is why I'm not just turning it off in disgust. But it is
hampered by this bad implementation detail.
[ And obviously I'm doing this now because system upgrades for me are
something that happen in the middle of the release cycle: don't do it
before or during travel, or just before or during the busy merge
window period. ]

- Initialize hash variables in ftrace subops logic
The fix that simplified the ftrace subops logic opened a path where some
variables could be used without being initialized, and done subtly where
the compiler did not catch it. Initialize those variables to the
EMPTY_HASH, which is the default hash.
- Reinitialize the hash pointers after they are freed
Some of the hash pointers in the subop logic were freed but may still be
referenced later. To prevent use-after-free bugs, initialize them back to
the EMPTY_HASH.
- Free the ftrace hashes when they are replaced
The fix that simplified the subops logic updated some hash pointers, but
left the original hash that they were pointing to where they are no longer
used. This caused a memory leak. Free the hashes that are pointed to by
the pointers when they are replaced.
- Fix size initialization of ftrace direct function hash
The ftrace direct function hash used by BPF initialized the hash size
incorrectly. It checked the size of items to a hard coded 32, which made
the hash bit size of 5. The hash size is supposed to be limited by the bit
size of the hash, as the bitmask is allowed to be greater than 5. Rework
the size check to first pass the number of elements to fls() and then
compare that to FTRACE_HASH_MAX_BITS before allocating the hash.
- Fix format output of ftrace_graph_ent_entry event
The field depth of the ftrace_graph_ent_entry event is of size 4 but the
output showed it as unsigned long and use "%lu". Change it to unsigned int
and use "%u" in the print format that is displayed to user space.
- Fix the trace event filter on strings
Events can be filtered on numbers or string values. The return value
checked from strncpy_from_kernel_nofault() and strncpy_from_user_nofault()
was used to determine if reading the strings would fault or not. It would
return fault if the value was non zero, which is basically meant that it
was always considering the read as a fault.
- Add selftest to test trace event string filtering
In order to catch the breakage of the string filtering, add a self test to
make sure that it continues to work.
