Devyn Liu adbc49a5a8 gpiolib: acpi: Fix failed in acpi_gpiochip_find() by adding parent node match
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: 067dbc1ea5 ("gpiolib: acpi: Don't use GPIO chip fwnode in acpi_gpiochip_find()")

Linus Torvalds db3d841ac9 fs/pidfs: make 'lsof' happy with our inode changes
pidfs started using much saner inodes in commit b28ddcc32d ("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.

Aaron Conole 30a92c9e3d openvswitch: Set the skbuff pkt_type for proper pmtud support.
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.

Qu Wenruo 440861b1a0 btrfs: re-introduce 'norecovery' mount option
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.

Thomas Gleixner 9d22c96316 x86/topology: Handle bogus ACPI tables correctly
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.

Sergey Shtylyov 3c0a2e0b0a nfs: fix undefined behavior in nfs_block_bits()
Shifting *signed int* typed constant 1 left by 31 bits causes undefined
behavior. Specify the correct *unsigned long* type by using 1UL instead.

Found by Linux Verification Center (linuxtesting.org) with the Svace static
analysis tool.

Marek Vasut d9ca4b760e drm/bridge: tc358767: Enable FRMSYNC timing generator
TC9595 datasheet Video Path0 Control (VPCTRL0) Register bit FRMSYNC description
says "This bit should be disabled only in video mode transmission where Host
transmits video timing together with video data and where pixel clock source
is from DSI clock." . This driver always sources pixel clock from external xtal,
therefore the FRMSYNC bit must always be enabled, enable it.

This fixes an actual issue with DSI-to-DPI mode, where the display would
randomly show subtle pixel flickering, or wobble, or shimmering. This is
visible on solid gray color, but the degree of the shimmering differs
between boots, which makes it hard to debug.

There is a caveat to the FRMSYNC and this bridge pixel PLL, which can only
generate pixel clock with limited accuracy, it may therefore be necessary
to reduce the HFP to fit into line length of input pixel data, to avoid any
possible overflows, which make the output video look striped horizontally.

Kuniyuki Iwashima e060e433e5 selftest: af_unix: Make SCM_RIGHTS into OOB data.
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.

Michal Luczaj 041933a1ec af_unix: Fix garbage collection of embryos carrying OOB with SCM_RIGHTS
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.

Kuniyuki Iwashima 3ebc46ca86 tcp: Fix shift-out-of-bounds in dctcp_update_alpha().
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
  10
  # echo 11 > /sys/module/tcp_dctcp/parameters/dctcp_shift_g

Test arp_ndisc_untracked_subnets use tcpdump to filter the unsolicited

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.

Kuniyuki Iwashima 9841991a44 af_unix: Update unix_sk(sk)->oob_skb under sk_receive_queue lock.
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

errors for you) and simplifies the code a bit.

One thing here that isn't just refactoring is that in a few places we
now check with errors with "if (err)" instead of "if (err < 0)". All
errors are expected to be negative so this is not expected to have any
impact. The _multi code internally considers anything non-zero to be
an error so this just makes things consistent.

It can also be noted that hx83102_prepare() has a mix of things that
can take advantage of _multi calls and things that can't. The cleanest
seemed to be to use the multi_ctx still but consistently use the
"accum_err" variable for error returns, though that's definitely a
style decision with pros and cons.

If mipi_dsi_dcs_set_display_on() returned an error then we'd store
that in the "ret" variable and jump to error handling. We'd then
attempt an orderly poweroff. Unfortunately we then blew away the value
stored in "ret". That means that if the orderly poweroff actually
worked then we're return 0 (no error) from hx8394_enable() even though
the panel wasn't enabled.

Fix this by not blowing away "ret".

Jarkko Sakkinen 050bf3c793 KEYS: trusted: Do not use WARN when encode fails
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.

Lang Yu eb853413d0 drm/amdkfd: Let VRAM allocations go to GTT domain on small APUs
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)
