2a829fe25d net/mlx5e: TC, Clean redundant counter flag from tc action parsers
When tc actions being parsed only the last flow attr created needs the
counter flag and the previous flags being reset.
Clean the flag from the tc action parsers.

a81283263b net/mlx5e: Use multi table support for CT and sample actions
CT and sample actions use post actions for their implementation.
Flag those actions as multi table actions so the post act infrastructure

8300f22526 net/mlx5e: Create new flow attr for multi table actions
Some TC actions use post actions for their implementation.
For example CT and sample actions.

Create a new flow attr after each multi table action and
create a post action rule for it.

First flow attr being offloaded normally and linked to the next
attr (post action rule) with setting an id on reg_c.
Post action rules match the id on reg_c and continue to the next one.

The flow counter is allocated on the last rule.

Introduce mlx5e_tc_post_act_offload() and mlx5e_tc_post_act_unoffload()
to be able to unoffload and reoffload existing post action rules handles.
For example in neigh update events, the driver removes and readds rules in
hardware.

0610f8dc03 net/mlx5e: Pass actions param to actions_match_supported()
Currently the mlx5_flow object contains a single mlx5_attr instance.
However, multi table actions (e.g. CT) instantiate multiple attr instances.

Currently action_match_supported() reads the actions flag from the
flow's attribute instance. Modify the function to receive the action
flags as a parameter which is set by the calling function and
pass the aggregated actions to actions_match_supported().

4b5fba4a3a net/mlx5e: RX, Restrict bulk size for small Striding RQs
In RQs of type multi-packet WQE (Striding RQ), each WQE is relatively
large (typically 256KB) but their number is relatively small (8 in
default).

Re-mapping the descriptors' buffers before re-posting them is done via
UMR (User-Mode Memory Registration) operations.

On the one hand, posting UMR WQEs in bulks reduces communication overhead
with the HW and better utilizes its processing units.
On the other hand, delaying the WQE repost operations for a small RQ
(say, of 4 WQEs) might drastically hit its performance, causing packet
drops due to no receive buffer, for high or bursty incoming packets rate.

Here we restrict the bulk size for too small RQs. Effectively, with the current
constants, RQ of size 4 (minimum allowed) would have no bulking, while larger
RQs will continue working with bulks of 2.

1d5024f88d net/mlx5e: Default to Striding RQ when not conflicting with CQE compression
CQE compression is turned on by default on slow pci systems to help
reduce the load on pci.
In this case, Striding RQ was turned off as CQEs of packets that span
several strides were not compressed, significantly reducing the compression
effectiveness.
This issue does not exist when using the newer mini_cqe format "stride_index".
Hence, allow defaulting to Striding RQ in this case.

baf682144e drm/i915: fix build issue when using clang
drm/i915 adds some extra cflags, namely -Wall, which causes instances of
-Wformat-security to appear when building with clang, even though this
warning is turned off kernel-wide in the main Makefile:

drivers/gpu/drm/i915/gt/intel_gt.c:983:2: error: format string is not a string literal (potentially insecure) [-Werror,-Wformat-security]

                do_trace_printk(fmt, ##__VA_ARGS__);    \

drivers/gpu/drm/i915/gt/intel_gt.c:983:2: note: treat the string as an argument to avoid this

This does not happen with GCC because it does not enable
-Wformat-security with -Wall. Disable -Wformat-security within the i915
Makefile so that these warnings do not show up with clang.

0b0dff5b3b ipv6: per-netns exclusive flowlabel checks
Ipv6 flowlabels historically require a reservation before use.
Optionally in exclusive mode (e.g., user-private).

Commit 59c820b231 ("ipv6: elide flowlabel check if no exclusive
leases exist") introduced a fastpath that avoids this check when no
exclusive leases exist in the system, and thus any flowlabel use
will be granted.

That allows skipping the control operation to reserve a flowlabel
entirely. Though with a warning if the fast path fails:

  This is an optimization. Robust applications still have to revert to
  requesting leases if the fast path fails due to an exclusive lease.

Still, this is subtle. Better isolate network namespaces from each
other. Flowlabels are per-netns. Also record per-netns whether
exclusive leases are in use. Then behavior does not change based on
activity in other netns.

Changes
  v2
    - wrap in IS_ENABLED(CONFIG_IPV6) to avoid breakage if disabled

c862033595 net: dsa: tag_8021q: only call skb_push/skb_pull around __skb_vlan_pop
__skb_vlan_pop() needs skb->data to point at the mac_header, while
skb_vlan_tag_present() and skb_vlan_tag_get() don't, because they don't
look at skb->data at all.

So we can avoid uselessly moving around skb->data for the case where the
VLAN tag was offloaded by the DSA master.

c832962ac9 net: bridge: multicast: notify switchdev driver whenever MC processing gets disabled
Whenever bridge driver hits the max capacity of MDBs, it disables
the MC processing (by setting corresponding bridge option), but never
notifies switchdev about such change (the notifiers are called only upon
explicit setting of this option, through the registered netlink interface).

This could lead to situation when Software MDB processing gets disabled,
but this event never gets offloaded to the underlying Hardware.

Fix this by adding a notify message in such case.

8f5fea65b0 blk-mq: avoid extending delays of active hctx from blk_mq_delay_run_hw_queues
When blk_mq_delay_run_hw_queues sets an hctx to run in the future, it can
reset the delay length for an already pending delayed work run_work. This
creates a scenario where multiple hctx may have their queues set to run,
but if one runs first and finds nothing to do, it can reset the delay of
another hctx and stall the other hctx's ability to run requests.

To avoid this I/O stall when an hctx's run_work is already pending,
leave it untouched to run at its current designated time rather than
extending its delay. The work will still run which keeps closed the race
calling blk_mq_delay_run_hw_queues is needed for while also avoiding the
I/O stall.

6dab421bfe memstick/mspro_block: fix handling of read-only devices
Use set_disk_ro to propagate the read-only state to the block layer
instead of checking for it in ->open and leaking a reference in case
of a read-only device.

e2efa07966 memstick/ms_block: simplify refcounting
Implement the ->free_disk method to free the msb_data structure only once
the last gendisk reference goes away instead of keeping a local refcount.

76792055c4 block: add a ->free_disk method
Add a method to notify the driver that the gendisk is about to be freed.
This allows drivers to tie the lifetime of their private data to that of
the gendisk and thus deal with device removal races without expensive
synchronization and boilerplate code.

A new flag is added so that ->free_disk is only called after a successful
call to add_disk, which significantly simplifies the error handling path
during probing.

Revert commit 4f1e9630af ("blk-throtl: optimize IOPS throttle for large

get better iops throttling result.

5a93b6027e block: don't try to throttle split bio if iops limit isn't set
We need to throttle split bio in case of IOPS limit even though the
split bio has been marked as BIO_THROTTLED since block layer
accounts split bio actually.

If only throughput throttle is setup, no need to throttle any more
if BIO_THROTTLED is set since we have accounted & considered the
whole bio bytes already.

Add one flag of THROTL_TG_HAS_IOPS_LIMIT for serving this purpose.

9f5ede3c01 block: throttle split bio in case of iops limit
Commit 111be88398 ("block-throttle: avoid double charge") marks bio as
BIO_THROTTLED unconditionally if __blk_throtl_bio() is called on this bio,
then this bio won't be called into __blk_throtl_bio() any more. This way
is to avoid double charge in case of bio splitting. It is reasonable for
read/write throughput limit, but not reasonable for IOPS limit because
block layer provides io accounting against split bio.

Chunguang Xu has already observed this issue and fixed it in commit
4f1e9630af ("blk-throtl: optimize IOPS throttle for large IO scenarios").
However, that patch only covers bio splitting in __blk_queue_split(), and
we have other kind of bio splitting, such as bio_split() &
submit_bio_noacct() and other ways.

This patch tries to fix the issue in one generic way by always charging
the bio for iops limit in blk_throtl_bio(). This way is reasonable:
re-submission & fast-cloned bio is charged if it is submitted to same
disk/queue, and BIO_THROTTLED will be cleared if bio->bi_bdev is changed.

This new approach can get much more smooth/stable iops limit compared with
commit 4f1e9630af ("blk-throtl: optimize IOPS throttle for large IO
scenarios") since that commit can't throttle current split bios actually.

Also this way won't cause new double bio iops charge in
blk_throtl_dispatch_work_fn() in which blk_throtl_bio() won't be called
any more.
