After consuming OOB data, recv() reading the preceding data must break at
the OOB skb regardless of MSG_PEEK.
Currently, MSG_PEEK does not stop recv() for AF_UNIX, and the behaviour is
not compliant with TCP.
>>> from socket import *
>>> c1, c2 = socketpair(AF_UNIX)
>>> c1.send(b'hello', MSG_OOB)
5
>>> c1.send(b'world')
5
>>> c2.recv(1, MSG_OOB)
b'o'
>>> c2.recv(9, MSG_PEEK) # This should return b'hell'
b'hellworld' # even with enough buffer.
Let's fix it by returning NULL for consumed skb and unlinking it only if
MSG_PEEK is not specified.
This patch also adds test cases that add recv(MSG_PEEK) before each recv().
Without fix:
# RUN msg_oob.peek.oob_ahead_break ...
# msg_oob.c:134:oob_ahead_break:AF_UNIX :hellworld
# msg_oob.c:135:oob_ahead_break:Expected:hell
# msg_oob.c:137:oob_ahead_break:Expected ret[0] (9) == expected_len (4)
# oob_ahead_break: Test terminated by assertion
# FAIL msg_oob.peek.oob_ahead_break
not ok 13 msg_oob.peek.oob_ahead_break
With fix:
# RUN msg_oob.peek.oob_ahead_break ...
# OK msg_oob.peek.oob_ahead_break
ok 13 msg_oob.peek.oob_ahead_break

AF_UNIX's MSG_OOB functionality lacked thorough testing, and we found
some bizarre behaviour.
The new selftest validates every MSG_OOB operation against TCP as a
reference implementation.
This patch adds only a few tests with basic send() and recv() that
do not fail.
The following patches will add more test cases for SO_OOBINLINE, SIGURG,
EPOLLPRI, and SIOCATMARK.

test_unix_oob.c does not fully cover AF_UNIX's MSG_OOB functionality,
thus there are discrepancies between TCP behaviour.
Also, the test uses fork() to create message producer, and it's not
easy to understand and add more test cases.
Let's remove test_unix_oob.c and rewrite a new test.

In the TRACE_EVENT(qdisc_reset) NULL dereference occurred from
qdisc->dev_queue->dev <NULL> ->name
This situation simulated from bunch of veths and Bluetooth disconnection
and reconnection.
During qdisc initialization, qdisc was being set to noop_queue.
In veth_init_queue, the initial tx_num was reduced back to one,
causing the qdisc reset to be called with noop, which led to the kernel
panic.
I've attached the GitHub gist link that C converted syz-execprogram
source code and 3 log of reproduced vmcore-dmesg.
https://gist.github.com/yskelg/cc64562873ce249cdd0d5a358b77d740
Yeoreum and I use two fuzzing tool simultaneously.
One process with syz-executor : https://github.com/google/syzkaller
$ ./syz-execprog -executor=./syz-executor -repeat=1 -sandbox=setuid \
-enable=none -collide=false log1
The other process with perf fuzzer:
https://github.com/deater/perf_event_tests/tree/master/fuzzer
$ perf_event_tests/fuzzer/perf_fuzzer
I think this will happen on the kernel version.
Linux kernel version +v6.7.10, +v6.8, +v6.9 and it could happen in v6.10.
This occurred from 51270d573a8d. I think this patch is absolutely
necessary. Previously, It was showing not intended string value of name.
I've reproduced 3 time from my fedora 40 Debug Kernel with any other module
or patched.

We've found a simple reproducer
# echo 1 > /sys/kernel/debug/tracing/events/qdisc/qdisc_reset/enable

Error: Unknown device type.
However, without our patch applied, I tested upstream 6.10.0-rc3 kernel
using the qdisc_reset event and the ip command on my qemu virtual machine.
This 2 commands makes always kernel panic.

FM350-GL is 5G Sub-6 WWAN module which uses M.2 form factor interface.
It is based on Mediatek's MTK T700 CPU. The module supports PCIe Gen3
x1 and USB 2.0 and 3.0 interfaces.
The manufacturer states that USB is "for debug" but it has been
confirmed to be fully functional, except for modem-control requests on
some of the interfaces.
USB device composition is controlled by AT+GTUSBMODE=<mode> command.
Two values are currently supported for the <mode>:
40: RNDIS+AT+AP(GNSS)+META+DEBUG+NPT+ADB
41: RNDIS+AT+AP(GNSS)+META+DEBUG+NPT+ADB+AP(LOG)+AP(META) (default value)
[ Note that the functions above are not ordered by interface number. ]
Mode 40 corresponds to:

v2 adds a test for removing contexts out of order. When testing

TX power index is read from the efuse on init, the values get written to
the TX power registers when the channel gets switched.
When the chip has not yet been calibrated, the efuse values are 0xFF,
which on some boards leads to USB timeouts for reading/writing registers
after the first frames have been sent.
The vendor driver (v5.11.5-1) checks for these invalid values and sets
default values instead. Implement something similar in
rtl8188fu_parse_efuse().

DPK is short for digital pre-distortion calibration. It can adjusts digital
waveform according to PA linear characteristics dynamically to enhance
TX EVM for high power.
Do this calibration when we are going to run on AP channel. To prevent
power offset out of boundary, it monitors thermal and set proper boundary
to register.

TSSI is transmitter signal strength indication, which is a close-loop
hardware circuit to feedback actual transmitting power as a reference for
next transmission.
It does full calibration when we are going to connect an AP. When switching
bands or channels for scanning or some reasons, reset hardware status to
prevent use wrong power value feedback from previous transmission.
It also loads tables of compensation values reflecting current temperature
into registers according to channel and band group to transmit packets
with expected power.

We add polling after sending LPS H2C to ensure that the Firmware is
received and executes RPWM thereafter. Otherwise, if the Firmware
executes RPWM without receiving LPS H2C, it will cause beacon loss in
WoWLAN mode due to the inability to obtain channel and bandwidth
information from H2C.

register store validation for NFT_DATA_VALUE is conditional, however,
the datatype is always either NFT_DATA_VALUE or NFT_DATA_VERDICT. This
only requires a new helper function to infer the register type from the
set datatype so this conditional check can be removed. Otherwise,
pointer to chain object can be leaked through the registers.

Currently, it's possible to pass in a modified CONST_PTR_TO_DYNPTR to
a global function as an argument. The adverse effects of this is that
BPF helpers can continue to make use of this modified
CONST_PTR_TO_DYNPTR from within the context of the global function,
which can unintentionally result in out-of-bounds memory accesses and
therefore compromise overall system stability i.e.

The currently existing of_property_present check for interrupts does not
cover all ways interrupts can be defined in a device tree, e.g.
"interrupts-extended".
In order to support all current and future ways that can be done, drop that
check and call of_irq_parse_one to figure out if an interrupt is defined
and irq_create_of_mapping for the actual mapping and let it be handled by
the interrupt subsystem.

After being asked about support for WPA3 for BCM43224 chipset it
was found that all it takes is setting the MFP_CAPABLE flag and
mac80211 will take care of all that is needed [1].

ath.git tree has moved to a new location. The old location will be an alias to
the new location and will work at least until end of 2024, but best to update
git trees already now.

We got sad news that Larry is not with us anymore. He was a long time
Linux developer, his first commit was back in 2005 and he has
maintained several wireless drivers over the years. He was known for
patiently supporting Linux users with all sorts of problems they had.
Larry's work helped so many people around the world and I always
enjoyed working with him, even though I sadly never met him.
Rest in Peace, Larry. You will be missed.

Work for __counted_by on generic pointers in structures (not just
flexible array members) has started landing in Clang 19 (current tip of
tree). During the development of this feature, a restriction was added
to __counted_by to prevent the flexible array member's element type from
including a flexible array member itself such as:
struct foo {
int count;
char buf[];
};
struct bar {
int count;
struct foo data[] __counted_by(count);
};
because the size of data cannot be calculated with the standard array
size formula:
sizeof(struct foo) * count
This restriction was downgraded to a warning but due to CONFIG_WERROR,
it can still break the build. The application of __counted_by on the fod
member of 'struct nvmet_fc_tgt_queue' triggers this restriction,
resulting in:
drivers/nvme/target/fc.c:151:2: error: 'counted_by' should not be applied to an array with element of unknown size because 'struct nvmet_fc_fcp_iod' is a struct type with a flexible array member. This will be an error in a future compiler version [-Werror,-Wbounds-safety-counted-by-elt-type-unknown-size]
151 | struct nvmet_fc_fcp_iod fod[] __counted_by(sqsize);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1 error generated.
Remove this use of __counted_by to fix the warning/error. However,
rather than remove it altogether, leave it commented, as it may be
possible to support this in future compiler releases.

Currently, the Rx data path only supports parsing peer metadata of version
zero. However, the QCN9274 platform configures the peer metadata version
as V1B. When V1B peer metadata is parsed using the version zero logic,
invalid data is populated, causing valid packets to be dropped. To address
this issue, refactor the peer metadata version and add the version based
parsing to populate the data from peer metadata correctly.

Pdev id from mac phy capabilities will be sent as a part of
HTT/WMI command to firmware. This causes issue with single pdev
devices where firmware does not respond to the WMI/HTT request
sent from host.
For single pdev devices firmware expects pdev id as 1 for 5 GHz/6 GHz
phy and 2 for 2 GHz band. Add wrapper ath12k_mac_get_target_pdev_id()
to help fetch right pdev for single pdev devices.
