The block layer doesn't support logical block sizes smaller than 512
bytes. The nvme spec doesn't support that small either, but the driver
isn't checking to make sure the device responded with usable data.
Failing to catch this will result in a kernel bug, either from a
division by zero when stacking, or a zero length bio.

blk-mq: don't count completed flush data request as inflight in case of quiesce
Request queue quiesce may interrupt flush sequence, and the original request
may have been marked as COMPLETE, but can't get finished because of
queue quiesce.
This way is fine from driver viewpoint, because flush sequence is block
layer concept, and it isn't related with driver.
However, driver(such as dm-rq) can call blk_mq_queue_inflight() to count &
drain inflight requests, then the wait & drain never gets done because
the completed & not-finished flush request is counted as inflight.
Fix this issue by not counting completed flush data request as inflight in
case of quiesce.

net: ravb: Keep reverse order of operations in ravb_remove()
On RZ/G3S SMARC Carrier II board having RGMII connections b/w Ethernet
MACs and PHYs it has been discovered that doing unbind/bind for ravb
driver in a loop leads to wrong speed and duplex for Ethernet links and
broken connectivity (the connectivity cannot be restored even with
bringing interface down/up). Before doing unbind/bind the Ethernet
interfaces were configured though systemd. The sh instructions used to
do unbind/bind were:
$ cd /sys/bus/platform/drivers/ravb/
$ while :; do echo
11c30000.ethernet > unbind ; \
echo
11c30000.ethernet > bind; done
It has been discovered that there is a race b/w IOCTLs initialized by
systemd at the response of success binding and the
"ravb_write(ndev, CCC_OPC_RESET, CCC)" call in ravb_remove() as
follows:
1/ as a result of bind success the user space open/configures the
interfaces tough an IOCTL; the following stack trace has been
identified on RZ/G3S:
Call trace:
dump_backtrace+0x9c/0x100
show_stack+0x20/0x38
dump_stack_lvl+0x48/0x60

el0_svc+0x34/0xb8
el0t_64_sync_handler+0xc0/0xc8
el0t_64_sync+0x190/0x198
2/ this call may execute concurrently with ravb_remove() as the
unbind/bind operation was executed in a loop
3/ if the operation mode is changed to RESET (through
ravb_write(ndev, CCC_OPC_RESET, CCC) call in ravb_remove())
while the above ravb_open() is in progress it may lead to MAC
(or PHY, or MAC-PHY connection, the right point hasn't been identified
at the moment) to be broken, thus the Ethernet connectivity fails to
restore.
The simple fix for this is to move ravb_write(ndev, CCC_OPC_RESET, CCC))
after unregister_netdev() to avoid resetting the controller while the
netdev interface is still registered.
To avoid future issues in ravb_remove(), the patch follows the proper order
of operations in ravb_remove(): reverse order compared with ravb_probe().
This avoids described races as the IOCTLs as well as unregister_netdev()
(called now at the beginning of ravb_remove()) calls rtnl_lock() before
continuing and IOCTLs check (though devinet_ioctl()) if device is still
registered just after taking the lock:
int devinet_ioctl(struct net *net, unsigned int cmd, struct ifreq *ifr)
{
// ...
rtnl_lock();
ret = -ENODEV;
dev = __dev_get_by_name(net, ifr->ifr_name);
if (!dev)
goto done;
// ...
done:
rtnl_unlock();
out:
return ret;

ice: Fix VF Reset paths when interface in a failed over aggregate
There is an error when an interface has the following conditions:
- PF is in an aggregate (bond)
- PF has VFs created on it
- bond is in a state where it is failed-over to the secondary interface
- A VF reset is issued on one or more of those VFs
The issue is generated by the originating PF trying to rebuild or
reconfigure the VF resources. Since the bond is failed over to the
secondary interface the queue contexts are in a modified state.
To fix this issue, have the originating interface reclaim its resources
prior to the tear-down and rebuild or reconfigure. Then after the process
is complete, move the resources back to the currently active interface.
There are multiple paths that can be used depending on what triggered the
event, so create a helper function to move the queues and use paired calls
to the helper (back to origin, process, then move back to active interface)
under the same lag_mutex lock.

bpf, sockmap: af_unix stream sockets need to hold ref for pair sock
AF_UNIX stream sockets are a paired socket. So sending on one of the pairs
will lookup the paired socket as part of the send operation. It is possible
however to put just one of the pairs in a BPF map. This currently increments
the refcnt on the sock in the sockmap to ensure it is not free'd by the
stack before sockmap cleans up its state and stops any skbs being sent/recv'd
to that socket.
But we missed a case. If the peer socket is closed it will be free'd by the
stack. However, the paired socket can still be referenced from BPF sockmap
side because we hold a reference there. Then if we are sending traffic through
BPF sockmap to that socket it will try to dereference the free'd pair in its
send logic creating a use after free. And following splat:

To fix let BPF sockmap hold a refcnt on both the socket in the sockmap and its
paired socket. It wasn't obvious how to contain the fix to bpf_unix logic. The
primarily problem with keeping this logic in bpf_unix was: In the sock close()
we could handle the deref by having a close handler. But, when we are destroying
the psock through a map delete operation we wouldn't have gotten any signal
thorugh the proto struct other than it being replaced. If we do the deref from
the proto replace its too early because we need to deref the sk_pair after the
backlog worker has been stopped.
Given all this it seems best to just cache it at the end of the psock and eat 8B
for the af_unix and vsock users. Notice dgram sockets are OK because they handle
locking already.

drm/amd/display: fix ABM disablement
On recent versions of DMUB firmware, if we want to completely disable
ABM we have to pass ABM_LEVEL_IMMEDIATE_DISABLE as the requested ABM
level to DMUB. Otherwise, LCD eDP displays are unable to reach their
maximum brightness levels. So, to fix this whenever the user requests an
ABM level of 0 pass ABM_LEVEL_IMMEDIATE_DISABLE to DMUB instead. Also,
to keep the user's experience consistent map ABM_LEVEL_IMMEDIATE_DISABLE
to 0 when a user tries to read the requested ABM level.

drm/amd/display: Update DCN35 clock table policy
[Why]
The new table doesn't have an implicit mapping between Fclk SOC voltage
and MemClk and it currently builds the table off of number of Fclk
states rather than DcfClock states.
The DML table in use is not correct for functionality or power and
does not align with our existing policies for DCN3x.
[How]
Build the table based on DcfClock with the following assumptions:
1. Raising Soc voltage is the most expensive operation, so assume that
running at max DispClock or DppClock is preferable.
2. Assume that we can run at max Fclk / MemClk at any state, but
restrict the maximum state to the very last entry in the table as the
worst case scenario.
3. Assume that Fclk always has a 2x multiplier on DcfClock unless the
table specifies something lower.

dm verity: don't perform FEC for failed readahead IO
We found an issue under Android OTA scenario that many BIOs have to do
FEC where the data under dm-verity is 100% complete and no corruption.
Android OTA has many dm-block layers, from upper to lower:
dm-verity
dm-snapshot
dm-origin & dm-cow
dm-linear
ufs
DM tables have to change 2 times during Android OTA merging process.
When doing table change, the dm-snapshot will be suspended for a while.
During this interval, many readahead IOs are submitted to dm_verity
from filesystem. Then the kverity works are busy doing FEC process
which cost too much time to finish dm-verity IO. This causes needless
delay which feels like system is hung.
After adding debugging it was found that each readahead IO needed
around 10s to finish when this situation occurred. This is due to IO
amplification:
dm-snapshot suspend
erofs_readahead // 300+ io is submitted
dm_submit_bio (dm_verity)
dm_submit_bio (dm_snapshot)
bio return EIO
bio got nothing, it's empty
verity_end_io
verity_verify_io
forloop range(0, io->n_blocks) // each io->nblocks ~= 20
verity_fec_decode
fec_decode_rsb
fec_read_bufs
forloop range(0, v->fec->rsn) // v->fec->rsn = 253
new_read
submit_bio (dm_snapshot)
end loop
end loop
dm-snapshot resume
Readahead BIOs get nothing while dm-snapshot is suspended, so all of
them will cause verity's FEC.
Each readahead BIO needs to verify ~20 (io->nblocks) blocks.
Each block needs to do FEC, and every block needs to do 253
(v->fec->rsn) reads.
So during the suspend interval(~200ms), 300 readahead BIOs trigger
~
1518000 (300*20*253) IOs to dm-snapshot.
As readahead IO is not required by userspace, and to fix this issue,
it is best to pass readahead errors to upper layer to handle it.

tools: ynl-gen: always construct struct ynl_req_state
struct ynl_req_state carries reply-related info from generated code
into generic YNL code. While we don't need reply info to execute
a request without a reply, we still need to pass in the struct, because
it's also where we get the pointer to struct ynl_sock from. Passing NULL
results in crashes if kernel returns an error or an unexpected reply.

ethtool: don't propagate EOPNOTSUPP from dumps
The default dump handler needs to clear ret before returning.
Otherwise if the last interface returns an inconsequential
error this error will propagate to user space.
This may confuse user space (ethtool CLI seems to ignore it,
but YNL doesn't). It will also terminate the dump early

cfe5bdfb27fa ("drm/i915: Check HPD live state during eDP probe")
fails to detect that the VBT's eDP/DDI-A is a ghost on
Asus B360M-A (CFL+CNP). On that board eDP/DDI-A has its HPD
asserted despite nothing being actually connected there :(
The straps/fuses also indicate that the eDP port is present.
So if one boots with a VGA monitor connected the eDP probe will
mistake the DP->VGA converter hooked to DDI-E for an eDP panel
on DDI-A.
As a last resort check what kind of DP device we've detected,
and if it looks like a DP->VGA converter then conclude that
the eDP port should be ignored.

drm/i915/gsc: Mark internal GSC engine with reserved uabi class
The GSC CS is not exposed to the user, so we skipped assigning a uabi
class number for it. However, the trace logs use the uabi class and

GSC CS show up as the RCS in those logs.
Given that the engine is not exposed to the user, we can't add a new
case in the uabi enum, so we insted internally define a kernel
internal class as -1.
At the same time remove special handling for the name and complete
the uabi_classes array so internal class is automatically correctly

nouveau/gsp: replace zero-length array with flex-array member and use __counted_by

PACKED_REGISTRY_TABLE`.
Also annotate array `entries` with `__counted_by()` to prepare for the
coming implementation by GCC and Clang of the `__counted_by` attribute.
Flexible array members annotated with `__counted_by` can have their
accesses bounds-checked at run-time via `CONFIG_UBSAN_BOUNDS` (for array
indexing) and `CONFIG_FORTIFY_SOURCE` (for strcpy/memcpy-family functions).
