As discussed on the mailing list, Chester is stepping down from being
the primary maintainer for the s32c platform, and Ghennadi becomes an
additional reviewer.
For the moment, there is no full maintainer for s32c, but Shawn is already
listed as the overall maintainer for 32-bit freescale/nxp platforms
(except layerscape and qoriq) and agreed to merge s32c patches as they
come in and are reviewed by the remaining reviewers.
Adapt the entries in the maintainers file based on the discussion.

same parent
Currently "btrfs subvolume snapshot -i <qgroupid>" would always mark the
qgroup inconsistent.
This can be annoying if the fs has a lot of snapshots, and needs qgroup
to get the accounting for the amount of bytes it can free for each
snapshot.
Although we have the new simple quote as a solution, there is also a
case where we can skip the full scan, if all the following conditions
are met:
- The source subvolume belongs to a higher level parent qgroup
- The parent qgroup already owns all its bytes exclusively
- The new snapshot is also added to the same parent qgroup
In that case, we only need to add nodesize to the parent qgroup and
avoid a full rescan.
This patch would add the extra quick accounting update for such inherit.

[BUG]
Currently btrfs can create subvolume with an invalid qgroup inherit
without triggering any error:
# mkfs.btrfs -O quota -f $dev
# mount $dev $mnt
# btrfs subvolume create -i 2/0 $mnt/subv1
# btrfs qgroup show -prce --sync $mnt
Qgroupid Referenced Exclusive Path
-------- ---------- --------- ----
0/5 16.00KiB 16.00KiB <toplevel>
0/256 16.00KiB 16.00KiB subv1
[CAUSE]
We only do a very basic size check for btrfs_qgroup_inherit structure,
but never really verify if the values are correct.
Thus in btrfs_qgroup_inherit() function, we have to skip non-existing
qgroups, and never return any error.
[FIX]
Fix the behavior and introduce extra checks:
- Introduce early check for btrfs_qgroup_inherit structure
Not only the size, but also all the qgroup ids would be verified.
And the timing is very early, so we can return error early.
This early check is very important for snapshot creation, as snapshot
is delayed to transaction commit.
- Drop support for btrfs_qgroup_inherit::num_ref_copies and
num_excl_copies
Those two members are used to specify to copy refr/excl numbers from
other qgroups.
This would definitely mark qgroup inconsistent, and btrfs-progs has
dropped the support for them for a long time.
It's time to drop the support for kernel.
- Verify the supported btrfs_qgroup_inherit::flags
Just in case we want to add extra flags for btrfs_qgroup_inherit.
Now above subvolume creation would fail with -ENOENT other than silently
ignore the non-existing qgroup.

The SLAB_MEM_SPREAD flag used to be implemented in SLAB, which was
removed as of v6.8-rc1, so it became a dead flag since the commit
16a1d968358a ("mm/slab: remove mm/slab.c and slab_def.h"). And the
series[1] went on to mark it obsolete to avoid confusion for users.
Here we can just remove all its users, which has no functional change.

[BUG]
If qgroup is marked inconsistent (e.g. caused by operations needing full
subtree rescan, like creating a snapshot and assign to a higher level
qgroup), btrfs would immediately start leaking its data reserved space.
The following script can easily reproduce it:
mkfs.btrfs -O quota -f $dev
mount $dev $mnt
btrfs subvolume create $mnt/subv1
btrfs qgroup create 1/0 $mnt
# This snapshot creation would mark qgroup inconsistent,
# as the ownership involves different higher level qgroup, thus
# we have to rescan both source and snapshot, which can be very
# time consuming, thus here btrfs just choose to mark qgroup
# inconsistent, and let users to determine when to do the rescan.
btrfs subv snapshot -i 1/0 $mnt/subv1 $mnt/snap1
# Now this write would lead to qgroup rsv leak.
xfs_io -f -c "pwrite 0 64k" $mnt/file1
# And at unmount time, btrfs would report 64K DATA rsv space leaked.
umount $mnt
And we would have the following dmesg output for the unmount:
BTRFS info (device dm-1): last unmount of filesystem 14a3d84e-f47b-4f72-b053-a8a36eef74d3
BTRFS warning (device dm-1): qgroup 0/5 has unreleased space, type 0 rsv 65536
[CAUSE]
Since commit e15e9f43c7ca ("btrfs: introduce
BTRFS_QGROUP_RUNTIME_FLAG_NO_ACCOUNTING to skip qgroup accounting"),
we introduce a mode for btrfs qgroup to skip the timing consuming
backref walk, if the qgroup is already inconsistent.
But this skip also covered the data reserved freeing, thus the qgroup
reserved space for each newly created data extent would not be freed,
thus cause the leakage.
[FIX]
Make the data extent reserved space freeing mandatory.
The qgroup reserved space handling is way cheaper compared to the
backref walking part, and we always have the super sensitive leak
detector, thus it's definitely worth to always free the qgroup
reserved data space.

[BUG]
There is a bug report about very suspicious tree-checker got triggered:
BTRFS critical (device dm-0): corrupted node, root=256
block=8550954455682405139 owner mismatch, have 11858205567642294356

SELinux: inode_doinit_use_xattr: getxattr returned 117 for dev=dm-0
ino=5737268
[ANALYZE]
The root cause is still unclear, but there are some clues already:
- Unaligned eb bytenr
The block bytenr is 8550954455682405139, which is not even aligned to
2.
This bytenr is fetched from extent buffer header, not from eb->start.
This means, at the initial time of read, eb header bytenr is still
correct (the very basis check to continue read), but later something
wrong happened, got at least the first page corrupted.
Thus we got such obviously incorrect value.
- Invalid extent buffer header owner
The read itself is triggered for subvolume 256, but the eb header
owner is 11858205567642294356, which is not really possible.
The problem here is, subvolume id is limited to (1 << 48 - 1),
and this one definitely goes beyond that limit.
So this value is another garbage.
We already got two garbage from an extent buffer, which passed the
initial bytenr and csum checks, but later the contents become garbage at
some point.
This looks like a page lifespan problem (e.g. we didn't properly hold the
page).
[ENHANCEMENT]
The current tree-checker only outputs things from the extent buffer,
nothing with the page status.
So this patch would enhance the tree-checker output by also dumping the
first page, which would look like this:
page:00000000aa9f3ce8 refcount:4 mapcount:0 mapping:00000000169aa6b6 index:0x1d0c pfn:0x1022e5
memcg:ffff888103456000
aops:btree_aops [btrfs] ino:1

raw: 0000000000001d0c ffff888102fdb1d8 00000004ffffffff ffff888103456000
page dumped because: eb page dump
BTRFS critical (device dm-3): corrupt leaf: root=5 block=30457856 slot=6 ino=257 file_offset=0, invalid disk_bytenr for file extent, have 10617606235235216665, should be aligned to 4096
BTRFS error (device dm-3): read time tree block corruption detected on logical 30457856 mirror 1
From the dump we can see some extra info, something can help us to do
extra cross-checks:
- Page refcount
if it's too low, it definitely means something bad.
- Page aops
Any mapped eb page should have btree_aops with inode number 1.
- Page index
Since a mapped eb page should has its bytenr matching the page
position, (index << PAGE_SHIFT) should match the bytenr of the
bytenr from the critical line.
- Page Private flags
A mapped eb page should have Private flag set to indicate it's managed
by btrfs.

Currently btrfs_subpage utilizes its atomic member @reader to manage the
reader counter. However it is only utilized to prevent the page to be
released/unlocked when we still have reads underway.
In that use case, we don't really allow multiple readers on the same
subpage sector. So here we can introduce a new locked bitmap to
represent exactly which subpage range is locked for read.
In theory we can remove btrfs_subpage::reader as it's just the set bits
of the new locked bitmap. But unfortunately bitmap doesn't provide such
handy API yet, so we still keep the reader counter.

On Arrow Lake S systems, MEI is no longer strictly connected to bus 0,
while graphics remain exclusively on bus 0. Adapt the component
matching logic to accommodate this change:
Original behavior: Required both MEI and graphics to be on the same
bus 0.
New behavior: Only enforces graphics to be on bus 0 (integrated),
allowing MEI to reside on any bus.
This ensures compatibility with Arrow Lake S and maintains functionality
for the legacy systems.

The comedi_test devices have a couple of timers (ai_timer and ao_timer)
that can be started to simulate hardware interrupts. Their expiry
functions normally reschedule the timer. The driver code calls either
del_timer_sync() or del_timer() to delete the timers from the queue, but
does not currently prevent the timers from rescheduling themselves so
synchronized deletion may be ineffective.
Add a couple of boolean members (one for each timer: ai_timer_enable and
ao_timer_enable) to the device private data structure to indicate
whether the timers are allowed to reschedule themselves. Set the member
to true when adding the timer to the queue, and to false when deleting
the timer from the queue in the waveform_ai_cancel() and
waveform_ao_cancel() functions.
The del_timer_sync() function is also called from the waveform_detach()
function, but the timer enable members will already be set to false when
that function is called, so no change is needed there.

The refactoring done in commit 5c57b1ccecc7 ("comedi: comedi_8255: Rework
subdevice initialization functions") to the initialization of the io
field of struct subdev_8255_private broke all cards using the
drivers/comedi/drivers/comedi_8255.c module.
Prior to 5c57b1ccecc7, __subdev_8255_init() initialized the io field
in the newly allocated struct subdev_8255_private to the non-NULL
callback given to the function, otherwise it used a flag parameter to
select between subdev_8255_mmio and subdev_8255_io. The refactoring
removed that logic and the flag, as subdev_8255_mm_init() and
subdev_8255_io_init() now explicitly pass subdev_8255_mmio and
subdev_8255_io respectively to __subdev_8255_init(), only
__subdev_8255_init() never sets spriv->io to the supplied
callback. That spriv->io is NULL leads to a later BUG:

Ring expansion checker may incorrectly assume a completely full ring
is empty, missing the need for expansion.
This is due to a special empty ring case where the dequeue ends up
ahead of the enqueue pointer. This is seen when enqueued TRBs fill up
exactly a segment, with enqueue then pointing to the end link TRB.
Once those TRBs are handled the dequeue pointer will follow the link
TRB and end up pointing to the first entry on the next segment, past
the enqueue.
This same enqueue - dequeue condition can be true if a ring is full,
with enqueue ending on that last link TRB before the dequeue pointer
on the next segment.
This can be seen when queuing several ~510 small URBs via usbfs in
one go before a single one is handled (i.e. dequeue not moved from first
entry in segment).
Expand the ring already when enqueue reaches the link TRB before the
dequeue segment, instead of expanding it when enqueue moves into the
dequeue segment.

This reverts commit 5c7e105cd156fc9adf5294a83623d7a40c15f9b9.
As identified by KASAN, the simplification done by the cleanup patch
was not legal.
>From tracing through the code, it can be seen that we're transmitting
from a 4096-byte circular buffer. We copy anywhere from 1-4 bytes from
it each time. The simplification runs into trouble when we get near
the end of the circular buffer. For instance, we might start out with
xmit->tail = 4094 and we want to transfer 4 bytes. With the code
before simplification this was no problem. We'd read buf[4094],
buf[4095], buf[0], and buf[1]. With the new code we'll do a
memcpy(&buf[4094], 4) which reads 2 bytes past the end of the buffer
and then skips transmitting what's at buf[0] and buf[1].
KASAN isn't 100% consistent at reporting this for me, but to be extra
confident in the analysis, I added traces of the tail and tx_bytes and
then wrote a test program:
while true; do
echo -n "abcdefghijklmnopqrstuvwxyz0" > /dev/ttyMSM0
sleep .1
done
I watched the traces over SSH and saw:
qcom_geni_serial_send_chunk_fifo: 4093 4
qcom_geni_serial_send_chunk_fifo: 1 3
Which indicated that one byte should be missing. Sure enough the
output that should have been:
abcdefghijklmnopqrstuvwxyz0
In one case was actually missing a byte:
abcdefghijklmnopqrstuvwyz0
Running "ls -al" on large directories also made the missing bytes
obvious since columns didn't line up.
While the original code may not be the most elegant, we only talking
about copying up to 4 bytes here. Let's just go back to the code that
worked.

If the remote uart device is not connected or not enabled after booting
up, the CTS line is high by default. At this time, if we enable the flow
control when opening the device(for example, using “stty -F /dev/ttyLP4
crtscts” command), there will be a pending idle preamble(first writing 0
and then writing 1 to UARTCTRL_TE will queue an idle preamble) that
cannot be sent out, resulting in the uart port fail to close(waiting for
TX empty), so the user space stty will have to wait for a long time or
forever.
This is an LPUART IP bug(idle preamble has higher priority than CTS),
here add a workaround patch to enable TX CTS after enabling UARTCTRL_TE,
so that the idle preamble does not get stuck due to CTS is deasserted.

Unused USB ports may have bogus location data in ACPI PLD tables.
This causes port peering failures as these unused USB2 and USB3 ports
location may match.
Due to these failures the driver prints a
"usb: port power management may be unreliable" warning, and
unnecessarily blocks port power off during runtime suspend.
This was debugged on a couple DELL systems where the unused ports
all returned zeroes in their location data.
Similar bugreports exist for other systems.
Don't try to peer or match ports that have connect type set to
USB_PORT_NOT_USED.

While connecting to a Linux host with CDC_NCM_NTB_DEF_SIZE_TX
set to 65536, it has been observed that we receive short packets,
which come at interval of 5-10 seconds sometimes and have block
length zero but still contain 1-2 valid datagrams present.
According to the NCM spec:
"If wBlockLength = 0x0000, the block is terminated by a
short packet. In this case, the USB transfer must still
be shorter than dwNtbInMaxSize or dwNtbOutMaxSize. If
exactly dwNtbInMaxSize or dwNtbOutMaxSize bytes are sent,
and the size is a multiple of wMaxPacketSize for the
given pipe, then no ZLP shall be sent.
wBlockLength= 0x0000 must be used with extreme care, because
of the possibility that the host and device may get out of
sync, and because of test issues.
wBlockLength = 0x0000 allows the sender to reduce latency by
starting to send a very large NTB, and then shortening it when
the sender discovers that there’s not sufficient data to justify
sending a large NTB"
However, there is a potential issue with the current implementation,
as it checks for the occurrence of multiple NTBs in a single
giveback by verifying if the leftover bytes to be processed is zero
or not. If the block length reads zero, we would process the same
NTB infintely because the leftover bytes is never zero and it leads
to a crash. Fix this by bailing out if block length reads zero.

device attribute group
The DisplayPort driver's sysfs nodes may be present to the userspace before
typec_altmode_set_drvdata() completes in dp_altmode_probe. This means that
a sysfs read can trigger a NULL pointer error by deferencing dp->hpd in
hpd_show or dp->lock in pin_assignment_show, as dev_get_drvdata() returns
NULL in those cases.
Remove manual sysfs node creation in favor of adding attribute group as
default for devices bound to the driver. The ATTRIBUTE_GROUPS() macro is
not used here otherwise the path to the sysfs nodes is no longer compliant

While commit 69f89168b310 ("usb: typec: tpcm: Fix issues with power being
removed during reset") fixes the boot issues for bus powered devices such
as LibreTech Renegade Elite/Firefly, it trades off the CC pins NOT being
Hi-Zed during errory recovery (i.e PORT_RESET) for devices which are NOT
bus powered(a.k.a self powered). This change Hi-Zs the CC pins only for
self powered devices, thus preventing brown out for bus powered devices
Adhering to spec is gaining more importance due to the Common charger
initiative enforced by the European Union.
Quoting from the spec:
4.5.2.2.2.1 ErrorRecovery State Requirements
The port shall not drive VBUS or VCONN, and shall present a
high-impedance to ground (above zOPEN) on its CC1 and CC2 pins.
Hi-Zing the CC pins is the inteded behavior for PORT_RESET.
CC pins are set to default state after tErrorRecovery in
PORT_RESET_WAIT_OFF.
4.5.2.2.2.2 Exiting From ErrorRecovery State
A Sink shall transition to Unattached.SNK after tErrorRecovery.
A Source shall transition to Unattached.SRC after tErrorRecovery.

In packet offload, packets are not encrypted in XFRM stack, so
the next network layer which the packets will be forwarded to
should depend on where the packet came from (either xfrm4_output
or xfrm6_output) rather than the matched SA's family type.

In current code, xfrm_bundle_create() always uses the matched
SA's family type to look up a xfrm child route for the skb.
The route returned by xfrm_dst_lookup() will eventually be
used in xfrm_output_resume() (skb_dst(skb)->ops->local_out()).
If packet offload is used, the above behavior can lead to
calling ip_local_out() for an IPv6 packet or calling
ip6_local_out() for an IPv4 packet, which is likely to fail.
This change fixes the behavior by checking if the matched SA
has packet offload enabled. If not, keep the same behavior;
if yes, use the matched SP's family type for the lookup.

The icl+ power well code currently assumes that every AUX power
well maps to an encoder which is using said power well. That is
by no menas guaranteed as we:
- only register encoders for ports declared in the VBT
- combo PHY HDMI-only encoder no longer get an AUX CH since
commit 9856308c94ca ("drm/i915: Only populate aux_ch if really needed")
However we have places such as intel_power_domains_sanitize_state()
that blindly traverse all the possible power wells. So these bits
of code may very well encounbter an aux power well with no associated
encoder.
In this particular case the BIOS seems to have left one AUX power
well enabled even though we're dealing with a HDMI only encoder
on a combo PHY. We then proceed to turn off said power well and
explode when we can't find a matching encoder. As a short term fix
we should be able to just skip the PHY related parts of the power
well programming since we know this situation can only happen with
combo PHYs.
Another option might be to go back to always picking an AUX CH for
all encoders. However I'm a bit wary about that since we might in
theory end up conflicting with the VBT AUX CH assignment. Also
that wouldn't help with encoders not declared in the VBT, should
we ever need to poke the corresponding power wells.
Longer term we need to figure out what the actual relationship
is between the PHY vs. AUX CH vs. AUX power well. Currently this
is entirely unclear.

On Goldmont p2sb_bar() only ever gets called for 2 devices, the actual P2SB
devfn 13,0 and the SPI controller which is part of the P2SB, devfn 13,2.
But the current p2sb code tries to cache BAR0 info for all of
devfn 13,0 to 13,7 . This involves calling pci_scan_single_device()
for device 13 functions 0-7 and the hw does not seem to like
pci_scan_single_device() getting called for some of the other hidden
devices. E.g. on an ASUS VivoBook D540NV-GQ065T this leads to continuous
ACPI errors leading to high CPU usage.
Fix this by only caching BAR0 info and thus only calling
pci_scan_single_device() for the P2SB and the SPI controller.

Patch "fs/aio: Make io_cancel() generate completions again" is based on the
assumption that calling kiocb->ki_cancel() does not complete R/W requests.
This is incorrect: the two drivers that call kiocb_set_cancel_fn() callers
set a cancellation function that calls usb_ep_dequeue(). According to its
documentation, usb_ep_dequeue() calls the completion routine with status
-ECONNRESET. Hence this revert.

Based on the static analyzis of the code it looks like when an entry
from the MAC table was removed, the entry was still used after being
freed. More precise the vid of the mac_entry was used after calling
devm_kfree on the mac_entry.
The fix consists in first using the vid of the mac_entry to delete the
entry from the HW and after that to free it.

Kishon updated his email in commit e6aa4edd2f5b ("MAINTAINERS: Update
Kishon's email address in PCI endpoint subsystem").
However, as he is no longer at TI, his TI email now bounces.
Add the same email as he has in MAINTAINERS to a mailmap, so that
get_maintainer.pl will not output an email that bounces.
(This is neeed as get_maintainer.pl will use "git author" to CC
people who have significantly modified the same file as you.)

We continue to see false positives from -Warray-bounds even in GCC 10,
which is getting reported in a few places[1] still:
security/security.c:811:2: warning: `memcpy' offset 32 is out of the bounds [0, 0] [-Warray-bounds]
Lower the GCC version check from 11 to 10.
