[ Upstream commit d3c1a8663d ]
According to the comment this DPU register contains the bits per pixel
as a 6.4 fractional value, conveniently matching the contents of
bits_per_pixel in struct drm_dsc_config which also uses 4 fractional
bits. However, the downstream source this implementation was
copy-pasted from has its bpp field stored _without_ fractional part.
This makes the entire convoluted math obsolete as it is impossible to
pull those 4 fractional bits out of thin air, by somehow trying to reuse
the lowest 2 bits of a non-fractional bpp (lsb = bpp % 4??).
The rest of the code merely attempts to keep the integer part a multiple
of 4, which is rendered useless thanks to data |= dsc->bits_per_pixel <<
12; already filling up those bits anyway (but not on downstream).

For the case where allow_ptr_leaks is false, code is checking whether
slot type is STACK_INVALID and STACK_SPILL and rejecting other cases.
This is a consequence of incorrectly checking for register type instead
of the slot type (NOT_INIT and SCALAR_VALUE respectively). Fix the

[ Upstream commit 261f4664ca ]
When support was added for spilled PTR_TO_BTF_ID to be accessed by
helper memory access, the stack slot was not overwritten to STACK_MISC
(and that too is only safe when env->allow_ptr_leaks is true).
This means that helpers who take ARG_PTR_TO_MEM and write to it may
essentially overwrite the value while the verifier continues to track
the slot for spilled register.
This can cause issues when PTR_TO_BTF_ID is spilled to stack, and then
overwritten by helper write access, which can then be passed to BPF
helpers or kfuncs.
Handle this by falling back to the case introduced in a later commit,
which will also handle PTR_TO_BTF_ID along with other pointer types,
i.e. cd17d38f8b ("bpf: Permits pointers on stack for helper calls").
Finally, include a comment on why REG_LIVE_WRITTEN is not being set when
clobber is set to true. In short, the reason is that while when clobber
is unset, we know that we won't be writing, when it is true, we *may*
write to any of the stack slots in that range. It may be a partial or
complete write, to just one or many stack slots.
We cannot be sure, hence to be conservative, we leave things as is and
never set REG_LIVE_WRITTEN for any stack slot. However, clobber still
needs to reset them to STACK_MISC assuming writes happened. However read
marks still need to be propagated upwards from liveness point of view,
as parent stack slot's contents may still continue to matter to child
states.

IMA relies on the blocking LSM policy notifier callback to update the
LSM based IMA policy rules.
When SELinux update its policies, IMA would be notified and starts
updating all its lsm rules one-by-one. During this time, -ESTALE would
be returned by ima_filter_rule_match() if it is called with a LSM rule
that has not yet been updated. In ima_match_rules(), -ESTALE is not
handled, and the LSM rule is considered a match, causing extra files
to be measured by IMA.
Fix it by re-initializing a temporary rule if -ESTALE is returned by
ima_filter_rule_match(). The origin rule in the rule list would be
updated by the LSM policy notifier callback.

If GuC is being used and we initialized GuC-error-capture,
we need to be warning if we don't provide an error-capture
register list in the firmware ADS, for valid GT engines.
A warning makes sense as this would impact debugability
without realizing why a reglist wasn't retrieved and reported
by GuC.
However, depending on the platform, we might have certain
engines that have a register list for engine instance error state
but not for engine class. Thus, add a check only to warn if the
register list was non existent vs an empty list (use the
empty lists to skip the warning).
NOTE: if a future platform were to introduce new registers
in place of what was an empty list on existing / legacy hardware
engines no warning is provided as the empty list is meant
to be used intentionally. As an example, if a future hardware
were to add blitter engine-class-registers (new) on top
of the legacy blitter engine-instance-register (HEAD, TAIL, etc.),
no warning is generated.

However, these events may occur at interface startup time before
kvaser_usb_open() has set the state to CAN_STATE_ERROR_ACTIVE, causing
restarts counter to increase and CAN_ERR_RESTARTED to be sent despite no
actual restart having occurred.
Fix that by making the auto-restart condition checks more strict so that

kvaser_usb_leaf_rx_error_update_can_state() sets error state according
to error counters when the hardware does not indicate a specific state
directly.
However, this is currently gated behind a check for
M16C_STATE_BUS_ERROR which does not always seem to be set when error
counters are increasing, and may not be set when error counters are
decreasing.
This causes the CAN_STATE_ERROR_WARNING state to not be set in some
cases even when appropriate.
Change the code to set error state from counters even without
M16C_STATE_BUS_ERROR.
The Error-Passive case seems superfluous as it is already set via
M16C_STATE_BUS_PASSIVE flag above, but it is kept for now.

[ Upstream commit f3c51fe02c ]
When examining module BTF, it is common to see core kernel structures
such as sk_buff, net_device duplicated in the module. After adding
debug messaging to BTF it turned out that much of the problem
was down to the identical struct test failing during deduplication;
sometimes the compiler adds identical structs. However
it turns out sometimes that type ids of identical struct members
can also differ, even when the containing structs are still identical.
To take an example, for struct sk_buff, debug messaging revealed
that the identical struct matching was failing for the anon
struct "headers"; specifically for the first field:
__u8 __pkt_type_offset[0]; /* 128 0 */
Looking at the code in BTF deduplication, we have code that guards
against the possibility of identical struct definitions, down to
type ids, and identical array definitions. However in this case
we have a struct which is being defined twice but does not have
identical type ids since each duplicate struct has separate type
ids for the above array member. A similar problem (though not
observed) could occur for struct-in-struct.
The solution is to make the "identical struct" test check members
not just for matching ids, but to also check if they in turn are
identical structs or arrays.
The results of doing this are quite dramatic (for some modules
at least); I see the number of type ids drop from around 10000
to just over 1000 in one module for example.
For testing use latest pahole or apply [1], otherwise dedups
can fail for the reasons described there.
Also fix return type of btf_dedup_identical_arrays() as
suggested by Andrii to match boolean return type used
elsewhere.

[ Upstream commit b261eda84e ]
Kazuho Oku reported that setsockopt(SO_INCOMING_CPU) does not work
with setsockopt(SO_REUSEPORT) since v4.6.
With the combination of SO_REUSEPORT and SO_INCOMING_CPU, we could
build a highly efficient server application.
setsockopt(SO_INCOMING_CPU) associates a CPU with a TCP listener
or UDP socket, and then incoming packets processed on the CPU will
likely be distributed to the socket. Technically, a socket could
even receive packets handled on another CPU if no sockets in the
reuseport group have the same CPU receiving the flow.
The logic exists in compute_score() so that a socket will get a higher
score if it has the same CPU with the flow. However, the score gets
ignored after the blamed two commits, which introduced a faster socket
selection algorithm for SO_REUSEPORT.
This patch introduces a counter of sockets with SO_INCOMING_CPU in
a reuseport group to check if we should iterate all sockets to find
a proper one. We increment the counter when
* calling listen() if the socket has SO_INCOMING_CPU and SO_REUSEPORT
* enabling SO_INCOMING_CPU if the socket is in a reuseport group
Also, we decrement it when
* detaching a socket out of the group to apply SO_INCOMING_CPU to
migrated TCP requests
* disabling SO_INCOMING_CPU if the socket is in a reuseport group
When the counter reaches 0, we can get back to the O(1) selection
algorithm.
The overall changes are negligible for the non-SO_INCOMING_CPU case,
and the only notable thing is that we have to update sk_incomnig_cpu
under reuseport_lock. Otherwise, the race prevents transitioning to
the O(n) algorithm and results in the wrong socket selection.

[ Upstream commit b6bcdf763d ]
The V4L2 API defines the maximum value for an integer menu control as
the number of elements minus one. The v4l2_ctrl_new_std_menu() validates
this constraint with an off-by-one error. Fix it.

[ Upstream commit 2f6fd23297 ]
Select variants of silicon do not define a default slider size, in
which case the size must be specified in the device tree. If it is
not, the axis's maximum value is reported as 65535 due to unsigned
integer overflow.
To solve this problem, move the existing zero-check outside of the
conditional block that checks whether the property is present.
