ata: ahci: Clean up sysfs file on error
.probe() (ahci_init_one()) calls sysfs_add_file_to_group(), however,
if probe() fails after this call, we currently never call
sysfs_remove_file_from_group().
(The sysfs_remove_file_from_group() call in .remove() (ahci_remove_one())
does not help, as .remove() is not called on .probe() error.)
Thus, if probe() fails after the sysfs_add_file_to_group() call, the next

x86-32: fix cmpxchg8b_emu build error with clang
The kernel test robot reported that clang no longer compiles the 32-bit
x86 kernel in some configurations due to commit
95ece48165c1
("locking/atomic/x86: Rewrite x86_32 arch_atomic64_{,fetch}_{and,or,xor}()
functions").
The build fails with
arch/x86/include/asm/cmpxchg_32.h:149:9: error: inline assembly requires more registers than available
and the reason seems to be that not only does the cmpxchg8b instruction
need four fixed registers (EDX:EAX and ECX:EBX), with the emulation
fallback the inline asm also wants a fifth fixed register for the
address (it uses %esi for that, but that's just a software convention
with cmpxchg8b_emu).
Avoiding using another pointer input to the asm (and just forcing it to
use the "0(%esi)" addressing that we end up requiring for the sw
fallback) seems to fix the issue.

x86: stop playing stack games in profile_pc()
The 'profile_pc()' function is used for timer-based profiling, which
isn't really all that relevant any more to begin with, but it also ends
up making assumptions based on the stack layout that aren't necessarily
valid.
Basically, the code tries to account the time spent in spinlocks to the
caller rather than the spinlock, and while I support that as a concept,
it's not worth the code complexity or the KASAN warnings when no serious
profiling is done using timers anyway these days.
And the code really does depend on stack layout that is only true in the
simplest of cases. We've lost the comment at some point (I think when
the 32-bit and 64-bit code was unified), but it used to say:
Assume the lock function has either no stack frame or a copy
of eflags from PUSHF.
which explains why it just blindly loads a word or two straight off the
stack pointer and then takes a minimal look at the values to just check
if they might be eflags or the return pc:
Eflags always has bits 22 and up cleared unlike kernel addresses
but that basic stack layout assumption assumes that there isn't any lock
debugging etc going on that would complicate the code and cause a stack
frame.
It causes KASAN unhappiness reported for years by syzkaller [1] and
others [2].
With no real practical reason for this any more, just remove the code.
Just for historical interest, here's some background commits relating to
this code from 2006:
0cb91a229364 ("i386: Account spinlocks to the caller during profiling for !FP kernels")
31679f38d886 ("Simplify profile_pc on x86-64")
and a code unification from 2009:
ef4512882dbe ("x86: time_32/64.c unify profile_pc")
but the basics of this thing actually goes back to before the git tree.

tty: mxser: Remove __counted_by from mxser_board.ports[]
Work for __counted_by on generic pointers in structures (not just
flexible array members) has started landing in Clang 19 (current tip of
tree). During the development of this feature, a restriction was added
to __counted_by to prevent the flexible array member's element type from
including a flexible array member itself such as:
struct foo {
int count;
char buf[];
};
struct bar {
int count;
struct foo data[] __counted_by(count);
};
because the size of data cannot be calculated with the standard array
size formula:
sizeof(struct foo) * count
This restriction was downgraded to a warning but due to CONFIG_WERROR,
it can still break the build. The application of __counted_by on the
ports member of 'struct mxser_board' triggers this restriction,
resulting in:
drivers/tty/mxser.c:291:2: error: 'counted_by' should not be applied to an array with element of unknown size because 'struct mxser_port' is a struct type with a flexible array member. This will be an error in a future compiler version [-Werror,-Wbounds-safety-counted-by-elt-type-unknown-size]
291 | struct mxser_port ports[] __counted_by(nports);
| ^~~~~~~~~~~~~~~~~~~~~~~~~
1 error generated.
Remove this use of __counted_by to fix the warning/error. However,
rather than remove it altogether, leave it commented, as it may be
possible to support this in future compiler releases.

randomize_kstack: Remove non-functional per-arch entropy filtering
An unintended consequence of commit
9c573cd31343 ("randomize_kstack:
Improve entropy diffusion") was that the per-architecture entropy size
filtering reduced how many bits were being added to the mix, rather than
how many bits were being used during the offsetting. All architectures
fell back to the existing default of 0x3FF (10 bits), which will consume
at most 1KiB of stack space. It seems that this is working just fine,
so let's avoid the confusion and update everything to use the default.
The prior intent of the per-architecture limits were:
arm64: capped at 0x1FF (9 bits), 5 bits effective
powerpc: uncapped (10 bits), 6 or 7 bits effective
riscv: uncapped (10 bits), 6 bits effective
x86: capped at 0xFF (8 bits), 5 (x86_64) or 6 (ia32) bits effective
s390: capped at 0xFF (8 bits), undocumented effective entropy
Current discussion has led to just dropping the original per-architecture
filters. The additional entropy appears to be safe for arm64, x86,
and s390. Quoting Arnd, "There is no point pretending that 15.75KB is
somehow safe to use while 15.00KB is not."

drm/drm_file: Fix pid refcounting race
<maarten.lankhorst@linux.intel.com>, Maxime Ripard
<mripard@kernel.org>, Thomas Zimmermann <tzimmermann@suse.de>
filp->pid is supposed to be a refcounted pointer; however, before this
patch, drm_file_update_pid() only increments the refcount of a struct
pid after storing a pointer to it in filp->pid and dropping the
dev->filelist_mutex, making the following race possible:
process A process B
========= =========
begin drm_file_update_pid
mutex_lock(&dev->filelist_mutex)
rcu_replace_pointer(filp->pid, <pid B>, 1)
mutex_unlock(&dev->filelist_mutex)
begin drm_file_update_pid
mutex_lock(&dev->filelist_mutex)
rcu_replace_pointer(filp->pid, <pid A>, 1)
mutex_unlock(&dev->filelist_mutex)
get_pid(<pid A>)
synchronize_rcu()
put_pid(<pid B>) *** pid B reaches refcount 0 and is freed here ***
get_pid(<pid B>) *** UAF ***
synchronize_rcu()
put_pid(<pid A>)
As far as I know, this race can only occur with CONFIG_PREEMPT_RCU=y
because it requires RCU to detect a quiescent state in code that is not
explicitly calling into the scheduler.
This race leads to use-after-free of a "struct pid".
It is probably somewhat hard to hit because process A has to pass
through a synchronize_rcu() operation while process B is between
mutex_unlock() and get_pid().
Fix it by ensuring that by the time a pointer to the current task's pid
is stored in the file, an extra reference to the pid has been taken.
This fix also removes the condition for synchronize_rcu(); I think
that optimization is unnecessary complexity, since in that case we
would usually have bailed out on the lockless check above.

kallsyms: rework symbol lookup return codes
Building with W=1 in some configurations produces a false positive
warning for kallsyms:
kernel/kallsyms.c: In function '__sprint_symbol.isra':
kernel/kallsyms.c:503:17: error: 'strcpy' source argument is the same as destination [-Werror=restrict]
503 | strcpy(buffer, name);
| ^~~~~~~~~~~~~~~~~~~~
This originally showed up while building with -O3, but later started
happening in other configurations as well, depending on inlining
decisions. The underlying issue is that the local 'name' variable is
always initialized to the be the same as 'buffer' in the called functions
that fill the buffer, which gcc notices while inlining, though it could
see that the address check always skips the copy.
The calling conventions here are rather unusual, as all of the internal
lookup functions (bpf_address_lookup, ftrace_mod_address_lookup,
ftrace_func_address_lookup, module_address_lookup and
kallsyms_lookup_buildid) already use the provided buffer and either return
the address of that buffer to indicate success, or NULL for failure,
but the callers are written to also expect an arbitrary other buffer
to be returned.
Rework the calling conventions to return the length of the filled buffer
instead of its address, which is simpler and easier to follow as well
as avoiding the warning. Leave only the kallsyms_lookup() calling conventions
unchanged, since that is called from 16 different functions and
adapting this would be a much bigger change.

gpiolib: cdev: Ignore reconfiguration without direction
linereq_set_config() behaves badly when direction is not set.
The configuration validation is borrowed from linereq_create(), where,
to verify the intent of the user, the direction must be set to in order to
effect a change to the electrical configuration of a line. But, when
applied to reconfiguration, that validation does not allow for the unset
direction case, making it possible to clear flags set previously without
specifying the line direction.
Adding to the inconsistency, those changes are not immediately applied by
linereq_set_config(), but will take effect when the line value is next get

For example, by requesting a configuration with no flags set, an output
line with GPIO_V2_LINE_FLAG_ACTIVE_LOW and GPIO_V2_LINE_FLAG_OPEN_DRAIN
set could have those flags cleared, inverting the sense of the line and
changing the line drive to push-pull on the next line value set.
Skip the reconfiguration of lines for which the direction is not set, and

de111f6b4f6a ("iommu/amd: Enable Guest Translation after reading
IOMMU feature register") missed to enable Control[GT] bit in resume
path. Its causing certain laptop to fail to resume after suspend.
This is because we have inconsistency between between control register
(GT is disabled) and DTE (where we have enabled guest translation related
bits) in resume path. And IOMMU hardware throws ILLEGAL_DEV_TABLE_ENTRY.
Fix it by enabling GT bit in resume path.

iommu/vt-d: Fix missed device TLB cache tag
When a domain is attached to a device, the required cache tags are
assigned to the domain so that the related caches can be flushed
whenever it is needed. The device TLB cache tag is created based
on whether the ats_enabled field of the device's iommu data is set.
This creates an ordered dependency between cache tag assignment and
ATS enabling.
The device TLB cache tag would not be created if device's ATS is
enabled after the cache tag assignment. This causes devices with PCI
ATS support to malfunction.
The ATS control is exclusively owned by the iommu driver. Hence, move
cache_tag_assign_domain() after PCI ATS enabling to make sure that the
device TLB cache tag is created for the domain.

iommu/amd: Invalidate cache before removing device from domain list
Commit
87a6f1f22c97 ("iommu/amd: Introduce per-device domain ID to fix
potential TLB aliasing issue") introduced per device domain ID when
domain is configured with v2 page table. And in invalidation path, it
uses per device structure (dev_data->gcr3_info.domid) to get the domain ID.
In detach_device() path, current code tries to invalidate IOMMU cache
after removing dev_data from domain device list. This means when domain
is configured with v2 page table, amd_iommu_domain_flush_all() will not be
able to invalidate cache as device is already removed from domain device
list.
This is causing change domain tests (changing domain type from identity to DMA)
to fail with IO_PAGE_FAULT issue.
Hence invalidate cache and update DTE before updating data structures.

af_unix: Don't stop recv(MSG_DONTWAIT) if consumed OOB skb is at the head.
Let's say a socket send()s "hello" with MSG_OOB and "world" without flags,
>>> from socket import *
>>> c1, c2 = socketpair(AF_UNIX)
>>> c1.send(b'hello', MSG_OOB)
5
>>> c1.send(b'world')
5
and its peer recv()s "hell" and "o".
>>> c2.recv(10)
b'hell'
>>> c2.recv(1, MSG_OOB)
b'o'
Now the consumed OOB skb stays at the head of recvq to return a correct
value for ioctl(SIOCATMARK), which is broken now and fixed by a later
patch.
Then, if peer issues recv() with MSG_DONTWAIT, manage_oob() returns NULL,
so recv() ends up with -EAGAIN.
>>> c2.setblocking(False) # This causes -EAGAIN even with available data
>>> c2.recv(5)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
BlockingIOError: [Errno 11] Resource temporarily unavailable
However, next recv() will return the following available data, "world".
>>> c2.recv(5)
b'world'
When the consumed OOB skb is at the head of the queue, we need to fetch
the next skb to fix the weird behaviour.
Note that the issue does not happen without MSG_DONTWAIT because we can
retry after manage_oob().
This patch also adds a test case that covers the issue.

nvmet-fc: Remove __counted_by from nvmet_fc_tgt_queue.fod[]
Work for __counted_by on generic pointers in structures (not just
flexible array members) has started landing in Clang 19 (current tip of
tree). During the development of this feature, a restriction was added
to __counted_by to prevent the flexible array member's element type from
including a flexible array member itself such as:
struct foo {
int count;
char buf[];
};
struct bar {
int count;
struct foo data[] __counted_by(count);
};
because the size of data cannot be calculated with the standard array
size formula:
sizeof(struct foo) * count
This restriction was downgraded to a warning but due to CONFIG_WERROR,
it can still break the build. The application of __counted_by on the fod
member of 'struct nvmet_fc_tgt_queue' triggers this restriction,
resulting in:
drivers/nvme/target/fc.c:151:2: error: 'counted_by' should not be applied to an array with element of unknown size because 'struct nvmet_fc_fcp_iod' is a struct type with a flexible array member. This will be an error in a future compiler version [-Werror,-Wbounds-safety-counted-by-elt-type-unknown-size]
151 | struct nvmet_fc_fcp_iod fod[] __counted_by(sqsize);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1 error generated.
Remove this use of __counted_by to fix the warning/error. However,
rather than remove it altogether, leave it commented, as it may be
possible to support this in future compiler releases.

logs a lot of arch_stack_walk and its sub-functions into the ftrace
buffer. However, these functions should not appear on the trace log
because they are part of the ftrace itself. This patch references what
arm64 does for the smae function. So it further prevent the re-enter
kprobe issue, which is also possible on riscv.

riscv: patch: Flush the icache right after patching to avoid illegal insns
We cannot delay the icache flush after patching some functions as we may
have patched a function that will get called before the icache flush.
The only way to completely avoid such scenario is by flushing the icache
as soon as we patch a function. This will probably be costly as we don't
batch the icache maintenance anymore.

i2c: viai2c: turn common code into a proper module
The i2c-viai2c-common.c file is used by two drivers, but is not a proper
abstraction and can get linked into both modules in the same configuration,
which results in a warning:
scripts/Makefile.build:236: drivers/i2c/busses/Makefile: i2c-viai2c-common.o is added to multiple modules: i2c-wmt i2c-zhaoxin
The other problems with this include the incorrect use of a __weak function
when both are built-in, and the fact that the "common" module is sprinked
with 'if (i2c->plat == ...)' checks that have knowledge about the differences
between the drivers using it.
Avoid the link time warning by making the common driver a proper module
with MODULE_LICENCE()/MODULE_AUTHOR() tags, and remove the __weak function
by slightly rearranging the code.
This adds a little more duplication between the two main drivers, but
those versions get more readable in the process.

xfs: honor init_xattrs in xfs_init_new_inode for !ATTR fs
xfs_init_new_inode ignores the init_xattrs parameter for filesystems
that do not have ATTR enabled. As a result, the first init_xattrs file
to be created by the kernel will not have an attr fork created to store
acls. Storing that first acl will add ATTR to the superblock flags, so
subsequent files will be created with attr forks. The overhead of this
is so small that chances are that nobody has noticed this behavior.
However, this is disastrous on a filesystem with parent pointers because
it requires that a new linkable file /must/ have a pre-existing attr
fork, and the parent pointers code uses init_xattrs to create that fork.
The preproduction version of mkfs.xfs used to set this, but the V5 sb
verifier only requires ATTR2, not ATTR. There is no guard for
filesystems with (PARENT && !ATTR).
It turns out that I misunderstood the two flags -- ATTR means that we at
some point created an attr fork to store xattrs in a file; ATTR2
apparently means only that inodes have dynamic fork offsets or that the
filesystem was mounted with the "attr2" option.
