The code implicitly operates on AMD-based systems by matching on PCI
IDs. However, the use of these IDs is going away.
Add an explicit CPU vendor check instead of relying on PCI IDs.

[ Upstream commit e638072e61 ]
Lockdep has a set of configs used to determine the size of the static
arrays that it uses. However, the upper limit that was initially setup
for these configs is too high (30 bit shift). This equates to several
GiB of static memory for individual symbols. Using such high values
leads to linker errors:
$ make defconfig
$ ./scripts/config -e PROVE_LOCKING --set-val LOCKDEP_BITS 30
$ make olddefconfig all
[...]
ld: kernel image bigger than KERNEL_IMAGE_SIZE
ld: section .bss VMA wraps around address space
Adjust the upper limits to the maximum values that avoid these issues.
The need for anything more, likely points to a problem elsewhere. Note
that LOCKDEP_CHAINS_BITS was intentionally left out as its upper limit
had a different symptom and has already been fixed [1].

[ Upstream commit 108ad09990 ]
When steal time exceeds the measured delta when updating clock_task, we
currently try to catch up the excess in future updates.
However, this results in inaccurate run times for the future things using
clock_task, in some situations, as they end up getting additional steal
time that did not actually happen.
This is because there is a window between reading the elapsed time in
update_rq_clock() and sampling the steal time in update_rq_clock_task().
If the VCPU gets preempted between those two points, any additional
steal time is accounted to the outgoing task even though the calculated
delta did not actually contain any of that "stolen" time.
When this race happens, we can end up with steal time that exceeds the
calculated delta, and the previous code would try to catch up that excess
steal time in future clock updates, which is given to the next,
incoming task, even though it did not actually have any time stolen.
This behavior is particularly bad when steal time can be very long,
which we've seen when trying to extend steal time to contain the duration
that the host was suspended [0]. When this happens, clock_task stays
frozen, during which the running task stays running for the whole
duration, since its run time doesn't increase.
However the race can happen even under normal operation.
Ideally we would read the elapsed cpu time and the steal time atomically,
to prevent this race from happening in the first place, but doing so
is non-trivial.
Since the time between those two points isn't otherwise accounted anywhere,
neither to the outgoing task nor the incoming task (because the "end of
outgoing task" and "start of incoming task" timestamps are the same),
I would argue that the right thing to do is to simply drop any excess steal
time, in order to prevent these issues.

[ Upstream commit 5324c4e10e ]
A data race occurs when the function `insert_ordered_extent_file_extent()`
and the function `btrfs_inode_safe_disk_i_size_write()` are executed
concurrently. The function `insert_ordered_extent_file_extent()` is not
locked when reading inode->disk_i_size, causing
`btrfs_inode_safe_disk_i_size_write()` to cause data competition when
writing inode->disk_i_size, thus affecting the value of `modify_tree`.
The specific call stack that appears during testing is as follows:
============DATA_RACE============
btrfs_drop_extents+0x89a/0xa060 [btrfs]
insert_reserved_file_extent+0xb54/0x2960 [btrfs]

kthread+0x292/0x330
ret_from_fork+0x4d/0x80
ret_from_fork_asm+0x1a/0x30
=================================
The main purpose of the check of the inode's disk_i_size is to avoid
taking write locks on a btree path when we have a write at or beyond
EOF, since in these cases we don't expect to find extent items in the
root to drop. However if we end up taking write locks due to a data
race on disk_i_size, everything is still correct, we only add extra
lock contention on the tree in case there's concurrency from other tasks.
If the race causes us to not take write locks when we actually need them,
then everything is functionally correct as well, since if we find out we
have extent items to drop and we took read locks (modify_tree set to 0),
we release the path and retry again with write locks.
Since this data race does not affect the correctness of the function,
it is a harmless data race, use data_race() to check inode->disk_i_size.

[ Upstream commit 543841d180 ]
Zbigniew mentioned at Linux Plumber's that systemd is interested in
switching to execveat() for service execution, but can't, because the
contents of /proc/pid/comm are the file descriptor which was used,
instead of the path to the binary[1]. This makes the output of tools like
top and ps useless, especially in a world where most fds are opened
CLOEXEC so the number is truly meaningless.
When the filename passed in is empty (e.g. with AT_EMPTY_PATH), use the
dentry's filename for "comm" instead of using the useless numeral from
the synthetic fdpath construction. This way the actual exec machinery
is unchanged, but cosmetically the comm looks reasonable to admins
investigating things.
Instead of adding TASK_COMM_LEN more bytes to bprm, use one of the unused
flag bits to indicate that we need to set "comm" from the dentry.

[BUG]
There is a bug report that btrfs outputs the following error message:
BTRFS info (device nvme0n1p2): qgroup scan completed (inconsistency flag cleared)
BTRFS warning (device nvme0n1p2): failed to cleanup qgroup 0/1179: -2
[CAUSE]
The error itself is pretty harmless, and the end user should ignore it.
When a subvolume is fully dropped, btrfs will call
btrfs_qgroup_cleanup_dropped_subvolume() to delete the qgroup.
However if a qgroup rescan happened before a subvolume fully dropped,
qgroup for that subvolume will not be re-created, as rescan will only
create new qgroup if there is a BTRFS_ROOT_REF_KEY found.
But before we drop a subvolume, the subvolume is unlinked thus there is no
BTRFS_ROOT_REF_KEY.
In that case, btrfs_remove_qgroup() will fail with -ENOENT and trigger
the above error message.
[FIX]
Just ignore -ENOENT error from btrfs_remove_qgroup() inside
btrfs_qgroup_cleanup_dropped_subvolume().

---[ end trace 0000000000000000 ]---
[CAUSE]
The first two lines of extra debug messages show the problem is caused
by the error handling of run_delalloc_nocow().
E.g. we have the following dirtied range (4K blocksize 4K page size):
0 16K 32K
|//////////////////////////////////////|
| Pre-allocated |
And the range [0, 16K) has a preallocated extent.
- Enter run_delalloc_nocow() for range [0, 16K)
Which found range [0, 16K) is preallocated, can do the proper NOCOW
write.
- Enter fallback_to_fow() for range [16K, 32K)
Since the range [16K, 32K) is not backed by preallocated extent, we
have to go COW.
- cow_file_range() failed for range [16K, 32K)
So cow_file_range() will do the clean up by clearing folio dirty,
unlock the folios.
Now the folios in range [16K, 32K) is unlocked.
- Enter extent_clear_unlock_delalloc() from run_delalloc_nocow()
Which is called with PAGE_START_WRITEBACK to start page writeback.
But folios can only be marked writeback when it's properly locked,
thus this triggered the VM_BUG_ON_FOLIO().
Furthermore there is another hidden but common bug that
run_delalloc_nocow() is not clearing the folio dirty flags in its error
handling path.
This is the common bug shared between run_delalloc_nocow() and
cow_file_range().
[FIX]
- Clear folio dirty for range [@start, @cur_offset)
Introduce a helper, cleanup_dirty_folios(), which
will find and lock the folio in the range, clear the dirty flag and
start/end the writeback, with the extra handling for the
@locked_folio.
- Introduce a helper to clear folio dirty, start and end writeback
- Introduce a helper to record the last failed COW range end
This is to trace which range we should skip, to avoid double
unlocking.
- Skip the failed COW range for the error handling

commit 021611d33e upstream.
Add a test case to ensure that attaching a tail callee program with an
freplace program fails, and that updating an extended program to a
prog_array map is also prohibited.
This test is designed to prevent the potential infinite loop issue caused
by the combination of tail calls and freplace, ensuring the correct
behavior and stability of the system.
Additionally, fix the broken tailcalls/tailcall_freplace selftest
because an extension prog should not be tailcalled.

commit cc00550b2a upstream.
This reverts commit ff123eb774.
Allowing large pages for KASAN shadow mappings isn't inherently wrong,
but adding POPULATE_KASAN_MAP_SHADOW to large_allowed() exposes an issue
in can_large_pud() and can_large_pmd().
Since commit d8073dc6bc ("s390/mm: Allow large pages only for aligned
physical addresses"), both can_large_pud() and can_large_pmd() call _pa()
to check if large page physical addresses are aligned. However, _pa()
has a side effect: it allocates memory in POPULATE_KASAN_MAP_SHADOW
mode. This results in massive memory leaks.
The proper fix would be to address both large_allowed() and _pa()'s side
effects, but for now, revert this change to avoid the leaks.

There is a recent ML report that mounting a large fs backed by hardware
RAID56 controller (with one device missing) took too much time, and
systemd seems to kill the mount attempt.
In that case, the only error message is:

There is no reason on why the failure happened, making it very hard to

At least output the error number (in the particular case it should be

kernel BUG at lib/list_debug.c:62!
Kernel panic - not syncing: Oops - BUG: Fatal exception
This happens because pps_device_destruct() frees the pps_device with the
embedded cdev immediately after calling cdev_del(), but, as the comment
above cdev_del() notes, fops for previously opened cdevs are still
callable even after cdev_del() returns. I think this bug has always
been there: I can't explain why it suddenly started happening every time
I reboot this particular board.
In commit d953e0e837 ("pps: Fix a use-after free bug when
unregistering a source."), George Spelvin suggested removing the
embedded cdev. That seems like the simplest way to fix this, so I've
implemented his suggestion, using __register_chrdev() with pps_idr
becoming the source of truth for which minor corresponds to which
device.
But now that pps_idr defines userspace visibility instead of cdev_add(),
we need to be sure the pps->dev refcount can't reach zero while
userspace can still find it again. So, the idr_remove() call moves to
pps_unregister_cdev(), and pps_idr now holds a reference to pps->dev.

But in fact, this blackhole was detected if any following SYN
retransmissions after a fallback to TCP was accepted.
That's because 'mptcp_subflow_early_fallback()' will set 'request_mptcp'
to 0, and 'mpc_drop' will never be reset to 0 after.
This is an issue, because some not so unusual situations might cause the
kernel to detect a false-positive blackhole, e.g. a client trying to
connect to a server while the network is not ready yet, causing a few
SYN retransmissions, before reaching the end server.

commit 4d27afbf25 upstream.
The Source can drop its output voltage to the minimum of the requested
PPS APDO voltage range when it is in Current Limit Mode. If this voltage
falls within the range of vPpsShutdown, the Source initiates a Hard
Reset and discharges Vbus. However, currently the Sink may disconnect
before the voltage reaches vPpsShutdown, leading to unexpected behavior.
Prevent premature disconnection by setting the Sink's disconnect
threshold to the minimum vPpsShutdown value. Additionally, consider the
voltage drop due to IR drop when calculating the appropriate threshold.
This ensures a robust and reliable interaction between the Source and
Sink during SPR PPS Current Limit Mode operation.

commit e3a9bd247c upstream.
When the system begins to enter suspend mode, dwc3_suspend() is called
by PM suspend. There is a problem that if someone interrupt the system
suspend process between dwc3_suspend() and pm_suspend() of its parent
device, PM suspend will be canceled and attempt to resume suspended
devices so that dwc3_resume() will be called. However, dwc3 and its
parent device (like the power domain or glue driver) may already be
suspended by runtime PM in fact. If this sutiation happened, the
pm_runtime_set_active() in dwc3_resume() will return an error since
parent device was suspended. This can lead to unexpected behavior if
DWC3 proceeds to execute dwc3_resume_common().
EX.
RPM suspend: ... -> dwc3_runtime_suspend()
-> rpm_suspend() of parent device
...
PM suspend: ... -> dwc3_suspend() -> pm_suspend of parent device
^ interrupt, so resume suspended device
... <- dwc3_resume() <-/
^ pm_runtime_set_active() returns error
To prevent the problem, this commit will skip dwc3_resume_common() and
return the error if pm_runtime_set_active() fails.

commit 66e0ea341a upstream.
Currently, DWC3 driver attempts to acquire the USB power supply only
once during the probe. If the USB power supply is not ready at that
time, the driver simply ignores the failure and continues the probe,
leading to permanent non-functioning of the gadget vbus_draw callback.
Address this problem by delaying the dwc3 driver initialization until
the USB power supply is registered.
