md: Whenassemble the array, consult the superblock of the freshest device
[ Upstream commit
dc1cc22ed58f11d58d8553c5ec5f11cbfc3e3039 ]
Upon assembling the array, both kernel and mdadm allow the devices to have event
counter difference of 1, and still consider them as up-to-date.
However, a device whose event count is behind by 1, may in fact not be up-to-date,
and array resync with such a device may cause data corruption.
To avoid this, consult the superblock of the freshest device about the status
of a device, whose event counter is behind by 1.

Driver has a logic leak in ring data allocation/free,
where aq_ring_free could be called multiple times on same ring,
if system is under stress and got memory allocation error.
Ring pointer was used as an indicator of failure, but this is
not correct since only ring data is allocated/deallocated.
Ring itself is an array member.
Changing ring allocation functions to return error code directly.

updates its service parameters such that priority tagging is no longer set,

Before this change, when operating in polled mode, i.e. no IRQ is
available, every individual C45 access would be hit with a 150us sleep
after the bus access.
For example, on a board with a CN9130 SoC connected to an MV88X3310

root@infix:~$ mdio
f212a600.mdio-mii mmd 4:1 bench 0xc003
Performed 1000 reads in 165ms
By replacing the long sleep with a tighter poll loop, we observe a 10x
increase in bus throughput:

minmax: allow min()/max()/clamp() if the arguments have the same signedness.
commit
d03eba99f5bf7cbc6e2fdde3b6fa36954ad58e09 upstream.
The type-check in min()/max() is there to stop unexpected results if a
negative value gets converted to a large unsigned value. However it also
rejects 'unsigned int' v 'unsigned long' compares which are common and
never problematc.
Replace the 'same type' check with a 'same signedness' check.
The new test isn't itself a compile time error, so use static_assert() to
report the error and give a meaningful error message.
Due to the way builtin_choose_expr() works detecting the error in the
'non-constant' side (where static_assert() can be used) also detects
errors when the arguments are constant.

minmax: add umin(a, b) and umax(a, b)
commit
80fcac55385ccb710d33a20dc1caaef29bd5a921 upstream.
Patch series "minmax: Relax type checks in min() and max()", v4.
The min() (etc) functions in minmax.h require that the arguments have
exactly the same types.
However when the type check fails, rather than look at the types and fix
the type of a variable/constant, everyone seems to jump on min_t(). In
reality min_t() ought to be rare - when something unusual is being done,
not normality.
The orginal min() (added in 2.4.9) replaced several inline functions and
included the type - so matched the implicit casting of the function call.
This was renamed min_t() in 2.4.10 and the current min() added. There is
no actual indication that the conversion of negatve values to large
unsigned values has ever been an actual problem.
A quick grep shows 5734 min() and 4597 min_t(). Having the casts on
almost half of the calls shows that something is clearly wrong.
If the wrong type is picked (and it is far too easy to pick the type of
the result instead of the larger input) then significant bits can get
discarded.
Pretty much the worst example is in the derived clamp_val(), consider:
unsigned char x = 200u;
y = clamp_val(x, 10u, 300u);
I also suspect that many of the min_t(u16, ...) are actually wrong. For
example copy_data() in printk_ringbuffer.c contains:
data_size = min_t(u16, buf_size, len);
Here buf_size is 'unsigned int' and len 'u16', pass a 64k buffer (can you
prove that doesn't happen?) and no data is returned. Apparantly it did -
and has since been fixed.
The only reason that most of the min_t() are 'fine' is that pretty much
all the values in the kernel are between 0 and INT_MAX.
Patch 1 adds umin(), this uses integer promotions to convert both
arguments to 'unsigned long long'. It can be used to compare a signed
type that is known to contain a non-negative value with an unsigned type.
The compiler typically optimises it all away. Added first so that it can
be referred to in patch 2.
Patch 2 replaces the 'same type' check with a 'same signedness' one. This
makes min(unsigned_int_var, sizeof()) be ok. The error message is also
improved and will contain the expanded form of both arguments (useful for
seeing how constants are defined).
Patch 3 just fixes some whitespace.
Patch 4 allows comparisons of 'unsigned char' and 'unsigned short' to
signed types. The integer promotion rules convert them both to 'signed
int' prior to the comparison so they can never cause a negative value be
converted to a large positive one.
Patch 5 (rewritted for v4) allows comparisons of unsigned values against
non-negative constant integer expressions. This makes
min(unsigned_int_var, 4) be ok.
The only common case that is still errored is the comparison of signed
values against unsigned constant integer expressions below __INT_MAX__.
Typcally min(int_val, sizeof (foo)), the real fix for this is casting the
constant: min(int_var, (int)sizeof (foo)).
With all the patches applied pretty much all the min_t() could be replaced
by min(), and most of the rest by umin(). However they all need careful
inspection due to code like:
sz = min_t(unsigned char, sz - 1, LIM - 1) + 1;
which converts 0 to LIM.
This patch (of 6):
umin() and umax() can be used when min()/max() errors a signed v unsigned
compare when the signed value is known to be non-negative.
Unlike min_t(some_unsigned_type, a, b) umin() will never mask off high
bits if an inappropriate type is selected.
The '+ 0u + 0ul + 0ull' may look strange.
The '+ 0u' is needed for 'signed int' on 64bit systems.
The '+ 0ul' is needed for 'signed long' on 32bit systems.
The '+ 0ull' is needed for 'signed long long'.

[ Upstream commit
b57c4db5d23b9df0118a25e2441c9288edd73710 ]
The current FC error recovery is sending up to three REC (recovery) frames
in 10 second intervals, and as a final step sending an ABTS after 30
seconds for the command itself. Unfortunately sending an ABTS is also the
action for the SCSI abort handler, and the default timeout for SCSI
commands is also 30 seconds. This causes two ABTS to be scheduled, with the
libfc one slightly earlier. The ABTS scheduled by SCSI EH then sees the
command to be already aborted, and will always return with a 'GOOD' status
irrespective on the actual result from the first ABTS. This causes the
SCSI EH abort handler to always succeed, and SCSI EH never to be engaged.
Fix this by not issuing an ABTS when a SCSI command is present for the
exchange, but rather wait for the abort scheduled from SCSI EH. And warn
if an abort is already scheduled to avoid similar errors in the future.

Both map deletion operation, map release and map free operation use
fd_array_map_delete_elem() to remove the element from fd array and
need_defer is always true in fd_array_map_delete_elem(). For the map
deletion operation and map release operation, need_defer=true is
necessary, because the bpf program, which accesses the element in fd
array, may still alive. However for map free operation, it is certain
that the bpf program which owns the fd array has already been exited, so
setting need_defer as false is appropriate for map free operation.
So fix it by adding need_defer parameter to bpf_fd_array_map_clear() and
adding a new helper __fd_array_map_delete_elem() to handle the map
deletion, map release and map free operations correspondingly.

wifi: rtw89: fix misbehavior of TX beacon in concurrent mode
[ Upstream commit
756b31203d482d2dd1aa6c208978b0410dc7530f ]
In concurrent mode, when STA interface is scanning, it causes
AP interface TX beacon on wrong channel. We modified it to scan
with the operating channel when one of the interfaces is already
connected. Additionally, STA interface need to stop scan when AP
interface is starting to avoid TX beacon on wrong channel. Finally,
AP interface need to stop TX beacon when STA interface is scanning
and switching to non-OP channel,This prevent other device to get
beacons on wrong channel.

wifi: ath11k: fix race due to setting ATH11K_FLAG_EXT_IRQ_ENABLED too early
[ Upstream commit
5082b3e3027eae393a4e86874bffb4ce3f83c26e ]
We are seeing below error randomly in the case where only
one MSI vector is configured:
kernel: ath11k_pci 0000:03:00.0: wmi command 16387 timeout
The reason is, currently, in ath11k_pcic_ext_irq_enable(),
ATH11K_FLAG_EXT_IRQ_ENABLED is set before NAPI is enabled.
This results in a race condition: after
ATH11K_FLAG_EXT_IRQ_ENABLED is set but before NAPI enabled,
CE interrupt breaks in. Since IRQ is shared by CE and data
path, ath11k_pcic_ext_interrupt_handler() is also called
where we call disable_irq_nosync() to disable IRQ. Then
napi_schedule() is called but it does nothing because NAPI
is not enabled at that time, meaning
ath11k_pcic_ext_grp_napi_poll() will never run, so we have
no chance to call enable_irq() to enable IRQ back. Finally
we get above error.
Fix it by setting ATH11K_FLAG_EXT_IRQ_ENABLED after all
NAPI and IRQ work are done. With the fix, we are sure that
by the time ATH11K_FLAG_EXT_IRQ_ENABLED is set, NAPI is
enabled.
Note that the fix above also introduce some side effects:
if ath11k_pcic_ext_interrupt_handler() breaks in after NAPI
enabled but before ATH11K_FLAG_EXT_IRQ_ENABLED set, nothing
will be done by the handler this time, the work will be
postponed till the next time the IRQ fires.

bpf: Fix a few selftest failures due to llvm18 change
[ Upstream commit

#356/17 test_global_funcs/global_func17:FAIL
#356 test_global_funcs:FAIL
Further analysis shows llvm upstream patch [1] is responsible for the above
failures. For example, for function bpf_fentry_test7() in net/bpf/test_run.c,
without [1], the asm code is:
0000000000000400 <bpf_fentry_test7>:
400: f3 0f 1e fa endbr64
404: e8 00 00 00 00 callq 0x409 <bpf_fentry_test7+0x9>
409: 48 89 f8 movq %rdi, %rax
40c: c3 retq
40d: 0f 1f 00 nopl (%rax)
... and with [1], the asm code is:
0000000000005d20 <bpf_fentry_test7.specialized.1>:
5d20: e8 00 00 00 00 callq 0x5d25 <bpf_fentry_test7.specialized.1+0x5>
5d25: c3 retq
... and <bpf_fentry_test7.specialized.1> is called instead of <bpf_fentry_test7>
and this caused test failures for #13/#77 etc. except #356.
For test case #356/17, with [1] (progs/test_global_func17.c)), the main prog
looks like:
0000000000000000 <global_func17>:
0: b4 00 00 00 2a 00 00 00 w0 = 0x2a
1: 95 00 00 00 00 00 00 00 exit
... which passed verification while the test itself expects a verification
failure.
Let us add 'barrier_var' style asm code in both places to prevent function
specialization which caused selftests failure.

If failed to allocate "tags" or could not find the final upper device from

So return -ENOMEM in alb_upper_dev_walk to stop walking, print some warn

I also think that the following function calls
netdev_walk_all_upper_dev_rcu
---->>>alb_upper_dev_walk
---------->>>bond_verify_device_path
From this way, "end device" can eventually be obtained from "start device"

selftests/bpf: Fix issues in setup_classid_environment()

If the net_cls subsystem is already mounted, attempting to mount it again

EBUSY. Despite this, tmpfs will have been successfully mounted at
/sys/fs/cgroup/net_cls. Consequently, the /sys/fs/cgroup/net_cls directory

[ Upstream commit

With latest clang18 (main branch of llvm-project repo), when building bpf selftests,
[~/work/bpf-next (master)]$ make -C tools/testing/selftests/bpf LLVM=1 -j
The following compilation error happens:

The compilation failure only happens to cpu=v2 and cpu=v3. cpu=v4 is okay
since cpu=v4 supports 32-bit branch target offset.
The above failure is due to upstream llvm patch [1] where some inlining behavior
are changed in clang18.
To workaround the issue, previously all 180 loop iterations are fully unrolled.
The bpf macro __BPF_CPU_VERSION__ (implemented in clang18 recently) is used to avoid
unrolling changes if cpu=v4. If __BPF_CPU_VERSION__ is not available and the
compiler is clang18, the unrollng amount is unconditionally reduced.

libbpf: Fix potential uninitialized tail padding with LIBBPF_OPTS_RESET
[ Upstream commit
7f7c43693c1b46652cfafb7af67ba31726d6ec4e ]
Martin reported that there is a libbpf complaining of non-zero-value tail
padding with LIBBPF_OPTS_RESET macro if struct bpf_netkit_opts is modified
to have a 4-byte tail padding. This only happens to clang compiler.
The commend line is: ./test_progs -t tc_netkit_multi_links
Martin and I did some investigation and found this indeed the case and
the following are the investigation details.
Clang:
clang version 18.0.0
<I tried clang15/16/17 and they all have similar results>
tools/lib/bpf/libbpf_common.h:
#define LIBBPF_OPTS_RESET(NAME, ...) \
do { \
memset(&NAME, 0, sizeof(NAME)); \
NAME = (typeof(NAME)) { \
.sz = sizeof(NAME), \
__VA_ARGS__ \
}; \
} while (0)
#endif
tools/lib/bpf/libbpf.h:
struct bpf_netkit_opts {
/* size of this struct, for forward/backward compatibility */
size_t sz;
__u32 flags;
__u32 relative_fd;
__u32 relative_id;
__u64 expected_revision;
size_t :0;
};
#define bpf_netkit_opts__last_field expected_revision
In the above struct bpf_netkit_opts, there is no tail padding.
prog_tests/tc_netkit.c:
static void serial_test_tc_netkit_multi_links_target(int mode, int target)
{
...
LIBBPF_OPTS(bpf_netkit_opts, optl);
...
LIBBPF_OPTS_RESET(optl,
.flags = BPF_F_BEFORE,
.relative_fd = bpf_program__fd(skel->progs.tc1),
);
...
}
Let us make the following source change, note that we have a 4-byte
tailing padding now.

; link = bpf_program__attach_netkit(skel->progs.tc2, ifindex, &optl);
At -O0 level, the clang compiler creates an intermediate copy.
We have below to store 'flags' with 4-byte store and leave another 4 byte
in the same 8-byte-aligned storage undefined,
5629: c7 85 28 fd ff ff 08 00 00 00 movl $0x8, -0x2d8(%rbp)
and later we store 8-byte to the original zero'ed buffer
5654: 48 8b 85 28 fd ff ff movq -0x2d8(%rbp), %rax
565b: 48 89 45 b0 movq %rax, -0x50(%rbp)
This caused a problem as the 4-byte value at [%rbp-0x2dc, %rbp-0x2e0)
may be garbage.
gcc (gcc 11.4) does not have this issue as it does zeroing struct first before
doing assignments:
; LIBBPF_OPTS_RESET(optl,
50fd: 48 8d 85 40 fc ff ff leaq -0x3c0(%rbp), %rax
5104: ba 20 00 00 00 movl $0x20, %edx

; link = bpf_program__attach_netkit(skel->progs.tc2, ifindex, &optl);
It is not clear how to resolve the compiler code generation as the compiler
generates correct code w.r.t. how to handle unnamed padding in C standard.
So this patch changed LIBBPF_OPTS_RESET macro to avoid uninitialized tail
padding. We already knows LIBBPF_OPTS macro works on both gcc and clang,
even with tail padding. So LIBBPF_OPTS_RESET is changed to be a
LIBBPF_OPTS followed by a memcpy(), thus avoiding uninitialized tail padding.
The below is asm code generated with this patch and with clang compiler:
; LIBBPF_OPTS_RESET(optl,
55e3: 48 8d bd 10 fd ff ff leaq -0x2f0(%rbp), %rdi
55ea: 31 f6 xorl %esi, %esi

; link = bpf_program__attach_netkit(skel->progs.tc2, ifindex, &optl);
In the above code, a temporary buffer is zeroed and then has proper value assigned.
Finally, values in temporary buffer are copied to the original variable buffer,
hence tail padding is guaranteed to be 0.

(PAGE_SIZE << MAX_ORDER) / sizeof(struct ext4_new_group_data) ≈ 21845
And the value that is down-aligned to the power of 2 is 16384. Therefore,
this value is defined as MAX_RESIZE_BG, and the number of groups added
each time does not exceed this value during resizing, and is added multiple
times to complete the online resizing. The difference is that the metadata
in a flex_bg may be more dispersed.

ext4: remove unnecessary check from alloc_flex_gd()
[ Upstream commit

In commit
967ac8af4475 ("ext4: fix potential integer overflow in
alloc_flex_gd()"), an overflow check is added to alloc_flex_gd() to
prevent the allocated memory from being smaller than expected due to
the overflow. However, after kmalloc() is replaced with kmalloc_array()
in commit
6da2ec56059c ("treewide: kmalloc() -> kmalloc_array()"), the
kmalloc_array() function has an overflow check, so the above problem
will not occur. Therefore, the extra check is removed.

ext4: unify the type of flexbg_size to unsigned int
[ Upstream commit
658a52344fb139f9531e7543a6e0015b630feb38 ]
The maximum value of flexbg_size is 2^31, but the maximum value of int
is (2^31 - 1), so overflow may occur when the type of flexbg_size is
declared as int.
For example, when uninit_mask is initialized in ext4_alloc_group_tables(),
if flexbg_size == 2^31, the initialized uninit_mask is incorrect, and this
may causes set_flexbg_block_bitmap() to trigger a BUG_ON().
Therefore, the flexbg_size type is declared as unsigned int to avoid
overflow and memory waste.

ext4: fix inconsistent between segment fstrim and full fstrim
[ Upstream commit

Suppose we issue two FITRIM ioctls for ranges [0,15] and [16,31] with
mininum length of trimmed range set to 8 blocks. If we have say a range of
blocks 10-22 free, this range will not be trimmed because it straddles the
boundary of the two FITRIM ranges and neither part is big enough. This is a
bit surprising to some users that call FITRIM on smaller ranges of blocks
to limit impact on the system. Also XFS trims all free space extents that
overlap with the specified range so we are inconsistent among filesystems.
Let's change ext4_try_to_trim_range() to consider for trimming the whole
free space extent that straddles the end of specified range, not just the
part of it within the range.

When registering tables to the sysctl subsystem there is a check to see
if header is a permanently empty directory (used for mounts). This check
evaluates the first element of the ctl_table. This results in an out of
bounds evaluation when registering empty directories.
The function register_sysctl_mount_point now passes a ctl_table of size

a permanently empty register.
Make sure that the ctl_table has at least one element before testing for

KVM: s390: fix setting of fpc register
[ Upstream commit
b988b1bb0053c0dcd26187d29ef07566a565cf55 ]
kvm_arch_vcpu_ioctl_set_fpu() allows to set the floating point control
(fpc) register of a guest cpu. The new value is tested for validity by
temporarily loading it into the fpc register.
This may lead to corruption of the fpc register of the host process:
if an interrupt happens while the value is temporarily loaded into the fpc
register, and within interrupt context floating point or vector registers
are used, the current fp/vx registers are saved with save_fpu_regs()
assuming they belong to user space and will be loaded into fp/vx registers
when returning to user space.
test_fp_ctl() restores the original user space / host process fpc register
value, however it will be discarded, when returning to user space.
In result the host process will incorrectly continue to run with the value
that was supposed to be used for a guest cpu.
Fix this by simply removing the test. There is another test right before
the SIE context is entered which will handles invalid values.
This results in a change of behaviour: invalid values will now be accepted
instead of that the ioctl fails with -EINVAL. This seems to be acceptable,
given that this interface is most likely not used anymore, and this is in
addition the same behaviour implemented with the memory mapped interface
(replace invalid values with zero) - see sync_regs() in kvm-s390.c.

s390/vfio-ap: fix sysfs status attribute for AP queue devices
[ Upstream commit
a0d8f4eeb7c4ffaee21702bcc91a09b3988c5b7a ]
The 'status' attribute for AP queue devices bound to the vfio_ap device
driver displays incorrect status when the mediated device is attached to a
guest, but the queue device is not passed through. In the current
implementation, the status displayed is 'in_use' which is not correct; it
should be 'assigned'. This can happen if one of the queue devices
associated with a given adapter is not bound to the vfio_ap device driver.
For example:
Queues listed in /sys/bus/ap/drivers/vfio_ap:
14.0005
14.0006
14.000d
16.0006
16.000d
Queues listed in /sys/devices/vfio_ap/matrix/$UUID/matrix
14.0005
14.0006
14.000d
16.0005
16.0006
16.000d
Queues listed in /sys/devices/vfio_ap/matrix/$UUID/guest_matrix
14.0005
14.0006
14.000d
The reason no queues for adapter 0x16 are listed in the guest_matrix is
because queue 16.0005 is not bound to the vfio_ap device driver, so no
queue associated with the adapter is passed through to the guest;
therefore, each queue device for adapter 0x16 should display 'assigned'
instead of 'in_use', because those queues are not in use by a guest, but
only assigned to the mediated device.
Let's check the AP configuration for the guest to determine whether a
queue device is passed through before displaying a status of 'in_use'.

Limit the waste of page tables and always align vmalloc area
size and base address on segment boundary.

[Analysis]
When the agstart is too large, it can cause agno overflow.
[Fix]
After obtaining agno, if the value is invalid, exit the subsequent process.

afs: fix the usage of read_seqbegin_or_lock() in afs_find_server*()
[ Upstream commit
1702e0654ca9a7bcd7c7619c8a5004db58945b71 ]
David Howells says:
(5) afs_find_server().
There could be a lot of servers in the list and each server can have
multiple addresses, so I think this would be better with an exclusive
second pass.
The server list isn't likely to change all that often, but when it does
change, there's a good chance several servers are going to be
added/removed one after the other. Further, this is only going to be
used for incoming cache management/callback requests from the server,
which hopefully aren't going to happen too often - but it is remotely
drivable.
(6) afs_find_server_by_uuid().
Similarly to (5), there could be a lot of servers to search through, but
they are in a tree not a flat list, so it should be faster to process.
Again, it's not likely to change that often and, again, when it does
change it's likely to involve multiple changes. This can be driven
remotely by an incoming cache management request but is mostly going to
be driven by setting up or reconfiguring a volume's server list -
something that also isn't likely to happen often.
Make the "seq" counter odd on the 2nd pass, otherwise read_seqbegin_or_lock()
never takes the lock.

David Howells says:
(2) afs_lookup_volume_rcu().
There can be a lot of volumes known by a system. A thousand would
require a 10-step walk and this is drivable by remote operation, so I
think this should probably take a lock on the second pass too.

crypto: stm32/crc32 - fix parsing list of devices

can 'crc' even be NULL?
Use list_first_entry_or_null instead of list_first_entry to retrieve
the first device registered.
The function list_first_entry always return a non NULL pointer even if
the list is empty. Hence checking if the pointer returned is NULL does
not tell if the list is empty or not.

erofs: fix up compacted indexes for block size < 4096
[ Upstream commit
8d2517aaeea3ab8651bb517bca8f3c8664d318ea ]
Previously, the block size always equaled to PAGE_SIZE, therefore
`lclusterbits` couldn't be less than 12.
Since sub-page compressed blocks are now considered, `lobits` for
a lcluster in each pack cannot always be `lclusterbits` as before.
Otherwise, there is no enough room for the special value
`Z_EROFS_LI_D0_CBLKCNT`.
To support smaller block sizes, `lobits` for each compacted lcluster is
now calculated as:
lobits = max(lclusterbits, ilog2(Z_EROFS_LI_D0_CBLKCNT) + 1)
