commit b29c457a6511435960115c0f548c4360d5f4801d upstream.
xt_compat_match/target_from_user doesn't check that zeroing the area
to start of next rule won't write past end of allocated ruleset blob.

BIT is unsigned long, which is 32-bit on ARCH=arm, hence the overflow

Setting the realtime clock triggers an IPI to all CPUs to reprogram
the clock event device.
However, only realtime and TAI clocks have their offsets updated
(and therefore potentially require a reprogram).
Instead of sending an IPI unconditionally, check each per CPU hrtimer base
whether it has

Hi Niklas,
I love your patch! Yet something to improve:

Some transceivers need a configuration step (for example, pulling the
standby or enable lines) for them to start sending messages. The
transceiver can be implemented as a phy with the configuration done in the
phy driver. The bit rate limitation can the be obtained by the driver
The following series of patches add support for implementing the
transceiver as a phy of m_can_platform driver.
TCAN1042 has a standby signal that needs to be pulled high for
sending/receiving messages[1]. TCAN1043 has a enable signal along with
standby signal that needs to be pulled up for sendin

Add support for implementing transceiver node as phy. The max_bitrate is
obtained by getting a phy attribute.

Hi,
We found a data race between tcp_set_default_congestion_control() and
tcp_set_congestion_control() in linux-5.12-rc3.
In general, when tcp_set_congestion_control() is reading ca->flags with a lock
grabbed, tcp_set_default_congestion_control()
may be updating ca->flags at the same time, as

The series add support for AMD SEV guest live migration commands. To protect the
confidentiality of an SEV protected guest memory while in transit we need to
use the SEV commands defined in SEV API spec [1].
SEV guest VMs have the concept of private and shared memory. Private
