When the timer instance was add into ack_list but was not currently in
process, the user could stop it via snd_timer_stop1() without delete it
from the ack_list. Then the user could free the timer instance and when
it was actually processed UAF occurred.
This issue could be reproduced via testcase snd_timer01 in ltp - running
several instances of that testcase at the same time.
What I actually met was that the ack_list of the timer broken and the
kernel went into deadloop with irqoff. That could be detected by
hardlockup detector on board or when we run it on qemu, we could use gdb
to dump the ack_list when the console has no response.
To fix this issue, we delete the timer instance from ack_list and
active_list unconditionally in snd_timer_stop1().

The VF can be configured via the PF's ndo ops at the same time the PF is
receiving/handling virtchnl messages. This has many issues, with
one of them being the ndo op could be actively resetting a VF (i.e.
resetting it to the default state and deleting/re-adding the VF's VSI)
while a virtchnl message is being handled. The following error was seen
because a VF ndo op was used to change a VF's trust setting while the
VIRTCHNL_OP_CONFIG_VSI_QUEUES was ongoing:
[35274.192484] ice 0000:88:00.0: Failed to set LAN Tx queue context, error: ICE_ERR_PARAM
[35274.193074] ice 0000:88:00.0: VF 0 failed opcode 6, retval: -5
[35274.193640] iavf 0000:88:01.0: PF returned error -5 (IAVF_ERR_PARAM) to our request 6
Fix this by making sure the virtchnl handling and VF ndo ops that
trigger VF resets cannot run concurrently. This is done by adding a
struct mutex cfg_lock to each VF structure. For VF ndo ops, the mutex
will be locked around the critical operations and VFR. Since the ndo ops
will trigger a VFR, the virtchnl thread will use mutex_trylock(). This
is done because if any other thread (i.e. VF ndo op) has the mutex, then
that means the current VF message being handled is no longer valid, so
just ignore it.
This issue can be seen using the following commands:
for i in {0..50}; do
rmmod ice
modprobe ice

When a VF is removed and/or reset its Tx queues need to be
stopped from the PF. This is done by calling the ice_dis_vf_qs()
function, which calls ice_vsi_stop_lan_tx_rings(). Currently
ice_dis_vf_qs() is protected by the VF state bit ICE_VF_STATE_QS_ENA.
Unfortunately, this is causing the Tx queues to not be disabled in some
cases and when the VF tries to re-enable/reconfigure its Tx queues over
virtchnl the op is failing. This is because a VF can be reset and/or
removed before the ICE_VF_STATE_QS_ENA bit is set, but the Tx queues
were already configured via ice_vsi_cfg_single_txq() in the
VIRTCHNL_OP_CONFIG_VSI_QUEUES op. However, the ICE_VF_STATE_QS_ENA bit
is set on a successful VIRTCHNL_OP_ENABLE_QUEUES, which will always
happen after the VIRTCHNL_OP_CONFIG_VSI_QUEUES op.
This was causing the following error message when loading the ice
driver, creating VFs, and modifying VF trust in an endless loop:
[35274.192484] ice 0000:88:00.0: Failed to set LAN Tx queue context, error: ICE_ERR_PARAM
[35274.193074] ice 0000:88:00.0: VF 0 failed opcode 6, retval: -5
[35274.193640] iavf 0000:88:01.0: PF returned error -5 (IAVF_ERR_PARAM) to our request 6
Fix this by always calling ice_dis_vf_qs() and silencing the error
message in ice_vsi_stop_tx_ring() since the calling code ignores the
return anyway. Also, all other places that call ice_vsi_stop_tx_ring()
catch the error, so this doesn't affect those flows since there was no
change to the values the function returns.
Other solutions were considered (i.e. tracking which VF queues had been
"started/configured" in VIRTCHNL_OP_CONFIG_VSI_QUEUES, but it seemed
more complicated than it was worth. This solution also brings in the
chance for other unexpected conditions due to invalid state bit checks.
So, the proposed solution seemed like the best option since there is no
harm in failing to stop Tx queues that were never started.
This issue can be seen using the following commands:
for i in {0..50}; do
rmmod ice
modprobe ice

When a VF requests promiscuous mode and it's trusted and true promiscuous
mode is enabled the PF driver attempts to enable unicast and/or
multicast promiscuous mode filters based on the request. This is fine,
but there are a couple issues with the current code.
[1] The define to configure the unicast promiscuous mode mask also
includes bits to configure the multicast promiscuous mode mask, which
causes multicast to be set/cleared unintentionally.
[2] All 4 cases for enable/disable unicast/multicast mode are not
handled in the promiscuous mode message handler, which causes
unexpected results regarding the current promiscuous mode settings.
To fix [1] make sure any promiscuous mask defines include the correct
bits for each of the promiscuous modes.
To fix [2] make sure that all 4 cases are handled since there are 2 bits
(FLAG_VF_UNICAST_PROMISC and FLAG_VF_MULTICAST_PROMISC) that can be
either set or cleared. Also, since either unicast and/or multicast
promiscuous configuration can fail, introduce two separate error values
to handle each of these cases.

Lots of code development have been see in ASoC side as usual, while
the continued development on memalloc helper and USB-audio low-
latency support are found in the rest. Note that a few changes in the
unusual places like arch/sh are included, which are a part of ASoC DAI
format cleanups.
ALSA core:
- Continued memallloc helper updates and cleanups, now supporting
non-coherent and non-contiguous pages
- Fixes for races in mixer OSS layer
ASoC:
- A new version of the audio graph card which supports a wider range
of systems
- Several conversions to YAML DT bindings
- Continuing cleanups to the SOF and Intel code
- Move of the Cirrus DSP framework into drivers/firmware to allow for
future use by non-audio DSPs
- An overhaul of the cs42l42 driver, correcting many problems
- DAI format terminology conversions over many drivers for cleanups
- Support for AMD Vangogh and Yelow Cap, Cirrus CS35L41, Maxim
MAX98520 and MAX98360A, Mediatek MT8195, Nuvoton NAU8821, nVidia
Tegra210, NXP i.MX8ULP, Qualcomm AudioReach, Realtek ALC5682I-VS,
RT5682S, and RT9120 and Rockchip RV1126 and RK3568
USB-audio:
- Continued improvements on low-latency playback
- Quirks for Pioneer devices, Line6 HX-Stomp XL, Audient iD14
HD-audio:
- Reduce excessive udelay() calls on Intel platforms; this should
reduce the CPU load with PulseAudio
- Quirks for HP and Clevo laptops
FireWire:
- Support for meter information on MOTU

Below is a simplified case from a report in bcc [0]:
r4 = 20
*(u32 *)(r10 -4) = r4
*(u32 *)(r10 -8) = r4 /* r4 state is tracked */
r4 = *(u64 *)(r10 -8) /* Read more than the tracked 32bit scalar.
* verifier rejects as 'corrupted spill memory'.
*/
After commit 354e8f1970 ("bpf: Support <8-byte scalar spill and refill"),
the 8-byte aligned 32bit spill is also tracked by the verifier and the
register state is stored.
However, if 8 bytes are read from the stack instead of the tracked 4 byte
scalar, then verifier currently rejects the program as "corrupted spill
memory". This patch fixes this case by allowing it to read but marks the
register as unknown.
Also note that, if the prog is trying to corrupt/leak an earlier spilled
pointer by spilling another <8 bytes register on top, this has already
been rejected in the check_stack_write_fixed_off().

When running `./test_progs -j` test_netcnt fails with a very high
probability, undercounting number of packets received (9999 vs expected
10000). It seems to be conflicting with other cgroup/skb selftests. So
make it serial for now to make parallel mode more robust.

Add tests to exercise the behaviour of RENAME_EXCHANGE and RENAME_NOREPLACE
on bpffs. The former checks that after an exchange the inode of two
directories has changed. The latter checks that the source still exists
after a failed rename. Generally, having support for renameat2(RENAME_EXCHANGE)
in bpffs fixes atomic upgrades of our sk_lookup control plane.
