Previous patch modified the standard used by acpi_gpiochip_find()
to match device nodes. Using the device node set in gc->gpiodev->d-
ev instead of gc->parent.
However, there is a situation in gpio-dwapb where the GPIO device
driver will set gc->fwnode for each port corresponding to a child
node under a GPIO device, so gc->gpiodev->dev will be assigned the
value of each child node in gpiochip_add_data().
gpio-dwapb.c:
128,31 static int dwapb_gpio_add_port(struct dwapb_gpio *gpio,
struct dwapb_port_property *pp,
unsigned int offs);
port->gc.fwnode = pp->fwnode;
693,39 static int dwapb_gpio_probe;
err = dwapb_gpio_add_port(gpio, &pdata->properties[i], i);
When other drivers request GPIO pin resources through the GPIO device
node provided by ACPI (corresponding to the parent node), the change
of the matching object to gc->gpiodev->dev in acpi_gpiochip_find()
only allows finding the value of each port (child node), resulting
in a failed request.
Reapply the condition of using gc->parent for match in acpi_gpio-
chip_find() in the code can compatible with the problem of gpio-dwapb,
and will not affect the two cases mentioned in the patch:
1. There is no setting for gc->fwnode.
2. The case that depends on using gc->fwnode for match.

Fixes: 067dbc1ea5ce ("gpiolib: acpi: Don't use GPIO chip fwnode in acpi_gpiochip_find()")

pidfs started using much saner inodes in commit b28ddcc32d8f ("pidfs:
convert to path_from_stashed() helper"), but that exposed the fact that
lsof had some knowledge of just how odd our old anon_inode usage was.
For example, legacy anon_inodes hadn't even initialized the inode type
in the inode mode, so everything had a type of zero.
So sane tools like 'stat' would report these files as "weird file", but
'lsof' instead used that (together with the name of the link in proc) to
notice that it's an anonymous inode, and used it to detect pidfd files.
Let's keep our internal new sane inode model, but mask the file type
bits at 'stat()' time in the getattr() function we already have, and by
making the dentry name match what lsof expects too.
This keeps our internal models sane, but should make user space see the
same old odd behavior.

Open vSwitch is originally intended to switch at layer 2, only dealing with
Ethernet frames. With the introduction of l3 tunnels support, it crossed
into the realm of needing to care a bit about some routing details when
making forwarding decisions. If an oversized packet would need to be
fragmented during this forwarding decision, there is a chance for pmtu
to get involved and generate a routing exception. This is gated by the
skbuff->pkt_type field.
When a flow is already loaded into the openvswitch module this field is
set up and transitioned properly as a packet moves from one port to
another. In the case that a packet execute is invoked after a flow is
newly installed this field is not properly initialized. This causes the
pmtud mechanism to omit sending the required exception messages across
the tunnel boundary and a second attempt needs to be made to make sure
that the routing exception is properly setup. To fix this, we set the
outgoing packet's pkt_type to PACKET_OUTGOING, since it can only get
to the openvswitch module via a port device or packet command.
Even for bridge ports as users, the pkt_type needs to be reset when
doing the transmit as the packet is truly outgoing and routing needs
to get involved post packet transformations, in the case of
VXLAN/GENEVE/udp-tunnel packets. In general, the pkt_type on output
gets ignored, since we go straight to the driver, but in the case of
tunnel ports they go through IP routing layer.
This issue is periodically encountered in complex setups, such as large
openshift deployments, where multiple sets of tunnel traversal occurs.
A way to recreate this is with the ovn-heater project that can setup
a networking environment which mimics such large deployments. We need
larger environments for this because we need to ensure that flow
misses occur. In these environment, without this patch, we can see:
./ovn_cluster.sh start
podman exec ovn-chassis-1 ip r a 170.168.0.5/32 dev eth1 mtu 1200
podman exec ovn-chassis-1 ip netns exec sw01p1 ip r flush cache
podman exec ovn-chassis-1 ip netns exec sw01p1 \
ping 21.0.0.3 -M do -s 1300 -c2
PING 21.0.0.3 (21.0.0.3) 1300(1328) bytes of data.
From 21.0.0.3 icmp_seq=2 Frag needed and DF set (mtu = 1142)
--- 21.0.0.3 ping statistics ---
...
Using tcpdump, we can also see the expected ICMP FRAG_NEEDED message is not
sent into the server.
With this patch, setting the pkt_type, we see the following:
podman exec ovn-chassis-1 ip netns exec sw01p1 \
ping 21.0.0.3 -M do -s 1300 -c2
PING 21.0.0.3 (21.0.0.3) 1300(1328) bytes of data.
From 21.0.0.3 icmp_seq=1 Frag needed and DF set (mtu = 1222)
ping: local error: message too long, mtu=1222
--- 21.0.0.3 ping statistics ---
...
In this case, the first ping request receives the FRAG_NEEDED message and
a local routing exception is created.

Although 'norecovery' mount option was marked as deprecated for a long
time and a warning message was printed during the deprecation window,
it's still actively utilized by several projects that need a safer way
to mount a btrfs without any writes.
Furthermore this 'norecovery' mount option is supported by other major
filesystems, which makes it less clear what's our motivation to remove
it.
Re-introduce the 'norecovery' mount option, and output a message to recommend
'rescue=nologreplay' option.

The ACPI specification clearly states how the processors should be
enumerated in the MADT:
"To ensure that the boot processor is supported post initialization,
two guidelines should be followed. The first is that OSPM should
initialize processors in the order that they appear in the MADT. The
second is that platform firmware should list the boot processor as the
first processor entry in the MADT.
...
Failure of OSPM implementations and platform firmware to abide by
these guidelines can result in both unpredictable and non optimal
platform operation."
The kernel relies on that ordering to detect the real BSP on crash kernels
which is important to avoid sending a INIT IPI to it as that would cause a
full machine reset.
On a Dell XPS 16 9640 the BIOS ignores this rule and enumerates the CPUs in
the wrong order. As a consequence the kernel falsely detects a crash kernel
and disables the corresponding CPU.
Prevent this by checking the IA32_APICBASE MSR for the BSP bit on the boot
CPU. If that bit is set, then the MADT based BSP detection can be safely
ignored. If the kernel detects a mismatch between the BSP bit and the first
enumerated MADT entry then emit a firmware bug message.
This obviously also has to be taken into account when the boot APIC ID and
the first enumerated APIC ID match. If the boot CPU does not have the BSP
bit set in the APICBASE MSR then there is no way for the boot CPU to
determine which of the CPUs is the real BSP. Sending an INIT to the real
BSP would reset the machine so the only sane way to deal with that is to
limit the number of CPUs to one and emit a corresponding warning message.

af_unix: Fix GC and improve selftest
Series deals with AF_UNIX garbage collector mishandling some in-flight
graph cycles. Embryos carrying OOB packets with SCM_RIGHTS cause issues.
Patch 1/2 fixes the memory leak.
Patch 2/2 tweaks the selftest for a better OOB coverage.

scm_rights.c covers various test cases for inflight file descriptors
and garbage collector for AF_UNIX sockets.
Currently, SCM_RIGHTS messages are sent with 3-bytes string, and it's
not good for MSG_OOB cases, as SCM_RIGTS cmsg goes with the first 2-bytes,
which is non-OOB data.
Let's send SCM_RIGHTS messages with 1-byte character to pack SCM_RIGHTS
into OOB data.

GC attempts to explicitly drop oob_skb's reference before purging the hit
list.
The problem is with embryos: kfree_skb(u->oob_skb) is never called on an
embryo socket.
The python script below [0] sends a listener's fd to its embryo as OOB
data. While GC does collect the embryo's queue, it fails to drop the OOB
skb's refcount. The skb which was in embryo's receive queue stays as
unix_sk(sk)->oob_skb and keeps the listener's refcount [1].
Tell GC to dispose embryo's oob_skb.

The compatible pattern "st,stm32-sai-sub-[ab]" is missing starting and

In dctcp_update_alpha(), we use a module parameter dctcp_shift_g
as follows:
alpha -= min_not_zero(alpha, alpha >> dctcp_shift_g);
...
delivered_ce <<= (10 - dctcp_shift_g);
It seems syzkaller started fuzzing module parameters and triggered
shift-out-of-bounds [0] by setting 100 to dctcp_shift_g:
memcpy((void*)0x20000080,
"/sys/module/tcp_dctcp/parameters/dctcp_shift_g\000", 47);
res = syscall(__NR_openat, /*fd=*/0xffffffffffffff9cul, /*file=*/0x20000080ul,
/*flags=*/2ul, /*mode=*/0ul);
memcpy((void*)0x20000000, "100\000", 4);
syscall(__NR_write, /*fd=*/r[0], /*val=*/0x20000000ul, /*len=*/4ul);
Let's limit the max value of dctcp_shift_g by param_set_uint_minmax().
With this patch:
# echo 10 > /sys/module/tcp_dctcp/parameters/dctcp_shift_g
# cat /sys/module/tcp_dctcp/parameters/dctcp_shift_g

# echo 11 > /sys/module/tcp_dctcp/parameters/dctcp_shift_g

Test arp_ndisc_untracked_subnets use tcpdump to filter the unsolicited
and untracked na messages. It set -e before calling tcpdump. But if
tcpdump filters 0 packet, it will return none zero, and cause the script
to exit.
Instead of using slow tcpdump to capture packets, let's using tc rule
to filter out the na message.
At the same time, fix function setup_v6 which only needs one parameter.
Move all the related helpers from forwarding lib.sh to net lib.sh.

Billy Jheng Bing-Jhong reported a race between __unix_gc() and
queue_oob().
__unix_gc() tries to garbage-collect close()d inflight sockets,
and then if the socket has MSG_OOB in unix_sk(sk)->oob_skb, GC
will drop the reference and set NULL to it locklessly.
However, the peer socket still can send MSG_OOB message and
queue_oob() can update unix_sk(sk)->oob_skb concurrently, leading
NULL pointer dereference. [0]
To fix the issue, let's update unix_sk(sk)->oob_skb under the
sk_receive_queue's lock and take it everywhere we touch oob_skb.
Note that we defer kfree_skb() in manage_oob() to silence lockdep
false-positive (See [1]).

Ken reported that RTL8125b can lock up if gro_flush_timeout has the
default value of 20000 and napi_defer_hard_irqs is set to 0.
In this scenario device interrupts aren't disabled, what seems to
trigger some silicon bug under heavy load. I was able to reproduce this
behavior on RTL8168h. Fix this by reverting 7274c4147afb.

When asn1_encode_sequence() fails, WARN is not the correct solution.
1. asn1_encode_sequence() is not an internal function (located
in lib/asn1_encode.c).
2. Location is known, which makes the stack trace useless.
3. Results a crash if panic_on_warn is set.
It is also noteworthy that the use of WARN is undocumented, and it
should be avoided unless there is a carefully considered rationale to
use it.
Replace WARN with pr_err, and print the return value instead, which is
only useful piece of information.

Small APUs(i.e., consumer, embedded products) usually have a small
carveout device memory which can't satisfy most compute workloads
memory allocation requirements.
We can't even run a Basic MNIST Example with a default 512MB carveout.
https://github.com/pytorch/examples/tree/main/mnist. Error Log:
"torch.cuda.OutOfMemoryError: HIP out of memory. Tried to allocate
84.00 MiB. GPU 0 has a total capacity of 512.00 MiB of which 0 bytes
is free. Of the allocated memory 103.83 MiB is allocated by PyTorch,
and 22.17 MiB is reserved by PyTorch but unallocated"
Though we can change BIOS settings to enlarge carveout size,
which is inflexible and may bring complaint. On the other hand,
the memory resource can't be effectively used between host and device.
The solution is MI300A approach, i.e., let VRAM allocations go to GTT.
Then device and host can flexibly and effectively share memory resource.
v2: Report local_mem_size_private as 0. (Felix)

Commit 2fd001cd3600 ("arch: Rename fbdev header and source files")
renames the video source files under arch/ such that they do not
refer to fbdev any longer. The new files named video.o conflict with
ACPI's video.ko module. Modprobing the ACPI module can then fail with
warnings about missing symbols, as shown below.
(i915_selftest:1107) igt_kmod-WARNING: i915: Unknown symbol acpi_video_unregister (err -2)
(i915_selftest:1107) igt_kmod-WARNING: i915: Unknown symbol acpi_video_register_backlight (err -2)

Pull f2fs updates from Jaegeuk Kim:
"In this round, we've tried to address some performance issues on zoned
storage such as direct IO and write_hints. In addition, we've migrated
some IO paths using folio. Meanwhile, there are multiple bug fixes in
the compression paths, sanity check conditions, and error handlers.
Enhancements:
- allow direct io of pinned files for zoned storage
- assign the write hint per stream by default
- convert read paths and test_writeback to folio
- avoid allocating WARM_DATA segment for direct IO
Bug fixes:
- fix false alarm on invalid block address
- fix to add missing iput() in gc_data_segment()
- fix to release node block count in error path of
f2fs_new_node_page()
- compress:
- don't allow unaligned truncation on released compress inode
- cover {reserve,release}_compress_blocks() w/ cp_rwsem lock
- fix error path of inc_valid_block_count()
- fix to update i_compr_blocks correctly
- fix block migration when section is not aligned to pow2
- don't trigger OPU on pinfile for direct IO
- fix to do sanity check on i_xattr_nid in sanity_check_inode()
- write missing last sum blk of file pinning section
- clear writeback when compression failed
- fix to adjust appropirate defragment pg_end
As usual, there are several minor code clean-ups, and fixes to manage
missing corner cases in the error paths"

Pull xfs updates from Chandan Babu:
"Online repair feature continues to be expanded. Also, we now support
delayed allocation for realtime devices which have an extent size that
is equal to filesystem's block size.
New code:
- Introduce Parent Pointer extended attribute for inodes
- Bring back delalloc support for realtime devices which have an
extent size that is equal to filesystem's block size
- Improve performance of log incompat feature handling
Online Repair:
- Implement atomic file content exchanges i.e. exchange ranges of
bytes between two files atomically
- Create temporary files to repair file-based metadata. This uses
atomic file content exchange facility to swap file fork mappings
between the temporary file and the metadata inode
- Allow callers of directory/xattr code to set an explicit owner
number to be written into the header fields of any new blocks that
are created. This is required to avoid walking every block of the
new structure and modify their ownership during online repair
- Repair more data structures:
- Extended attributes
- Inode unlinked state
- Directories
- Symbolic links
- AGI's unlinked inode list
- Parent pointers
- Move Orphan files to lost and found directory
- Fixes for Inode repair functionality
- Introduce a new sub-AG FITRIM implementation to reduce the duration
for which the AGF lock is held
- Updates for the design documentation
- Use Parent Pointers to assist in checking directories, parent
pointers, extended attributes, and link counts
Fixes:
- Prevent userspace from reading invalid file data due to incorrect.
updation of file size when performing a non-atomic clone operation
- Minor fixes to online repair
- Fix confusing return values from xfs_bmapi_write()
- Fix an out of bounds access due to incorrect h_size during log
recovery
- Defer upgrading the extent counters in xfs_reflink_end_cow_extent()
until we know we are going to modify the extent mapping
- Remove racy access to if_bytes check in
xfs_reflink_end_cow_extent()
- Fix sparse warnings
Cleanups:
- Hold inode locks on all files involved in a rename until the
completion of the operation. This is in preparation for the parent
pointers patchset where parent pointers are applied in a separate
chained update from the actual directory update
- Compile out v4 support when disabled
- Cleanup xfs_extent_busy_clear()
- Remove unused flags and fields from struct xfs_da_args
- Remove definitions of unused functions
- Improve extended attribute validation
- Add higher level directory operations helpers to remove duplication
of code
- Cleanup quota (un)reservation interfaces"

Commit 4f563a64732d ("block: add a max_user_discard_sectors queue
limit") changed block core to set max_discard_sectors to:
min(lim->max_hw_discard_sectors, lim->max_user_discard_sectors)
Since commit 1c0e720228ad ("dm: use queue_limits_set") it was reported
dm-thinp was failing in a few fstests (generic/347 and generic/405)
with the first WARN_ON_ONCE in dm_cell_key_has_valid_range() being
reported, e.g.:
WARNING: CPU: 1 PID: 30 at drivers/md/dm-bio-prison-v1.c:128 dm_cell_key_has_valid_range+0x3d/0x50
blk_set_stacking_limits() sets max_user_discard_sectors to UINT_MAX,
so given how block core now sets max_discard_sectors (detailed above)
it follows that blk_stack_limits() stacks up the underlying device's
max_hw_discard_sectors and max_discard_sectors is set to match it. If
max_hw_discard_sectors exceeds dm's BIO_PRISON_MAX_RANGE, then
dm_cell_key_has_valid_range() will trigger the warning with:
WARN_ON_ONCE(key->block_end - key->block_begin > BIO_PRISON_MAX_RANGE)
Aside from this warning, the discard will fail. Fix this and other DM
issues by governing discard support in terms of max_hw_discard_sectors
instead of max_discard_sectors.

This reverts commit e6595224464b692ddae193d783402130d1625147.
These kinds of patches are only making the code worse.
Compilers don't care about the unnecessary check, but removing it makes
the code less obvious to a human. The declaration of 'len' is more than
80 lines earlier, so a human won't easily see that 'len' is of an
unsigned type, so to a human the range check that checks against zero is
much more explicit and obvious.
Any tool that complains about a range check like this just because the
variable is unsigned is actively detrimental, and should be ignored.
