When devlink instance is put into network namespace and that network
namespace gets deleted, devlink instance is moved back into init_ns.
This is done as a part of cleanup_net() routine. Since cleanup_net()
is called asynchronously from workqueue, there is no guarantee that
the devlink instance move is done after "ip netns del" returns.
So fix this race by making sure that the devlink instance is present
before any other operation.

Usage of `set -e` before executing a command causes immediate exit
on failure, without cleanup up the resources allocated at setup.
This can affect the next tests that use the same resources,
leading to a chain of failures.
A simple fix is to always call cleanup function when the script exists.
This approach is already used by other existing tests.

net/sched: cls_api: Support hardware miss to tc action
This series adds support for hardware miss to instruct tc to continue execution
in a specific tc action instance on a filter's action list. The mlx5 driver patch
(besides the refactors) shows its usage instead of using just chain restore.
Currently a filter's action list must be executed all together or
not at all as driver are only able to tell tc to continue executing from a
specific tc chain, and not a specific filter/action.
This is troublesome with regards to action CT, where new connections should
be sent to software (via tc chain restore), and established connections can
be handled in hardware.
Checking for new connections is done when executing the ct action in hardware
(by checking the packet's tuple against known established tuples).
But if there is a packet modification (pedit) action before action CT and the
checked tuple is a new connection, hardware will need to revert the previous
packet modifications before sending it back to software so it can
re-match the same tc filter in software and re-execute its CT action.
The following is an example configuration of stateless nat
on mlx5 driver that isn't supported before this patchet:
#Setup corrosponding mlx5 VFs in namespaces
$ ip netns add ns0
$ ip netns add ns1
$ ip link set dev enp8s0f0v0 netns ns0
$ ip netns exec ns0 ifconfig enp8s0f0v0 1.1.1.1/24 up

$ ip netns exec ns1 ifconfig enp8s0f0v1 1.1.1.2/24 up
#Setup tc arp and ct rules on mxl5 VF representors
$ tc qdisc add dev enp8s0f0_0 ingress

ct_state -trk ip_proto tcp \
action ct pipe \
action pedit ex munge tcp sport set 8888 pipe \
action csum ip tcp pipe \
action mirred egress redirect dev enp8s0f0_0
#Run traffic
$ ip netns exec ns1 iperf -s -p 5001&
$ sleep 2 #wait for iperf to fully open
$ ip netns exec ns0 iperf -c 1.1.1.2 -p 8888
#dump tc filter stats on enp8s0f0_0 chain 0 rule and see hardware packets:
$ tc -s filter show dev enp8s0f0_0 ingress chain 0 proto ip | grep "hardware.*pkt"
Sent hardware 9310116832 bytes 6149672 pkt
Sent hardware 9310116832 bytes 6149672 pkt
Sent hardware 9310116832 bytes 6149672 pkt
A new connection executing the first filter in hardware will first rewrite
the dst port to the new port, and then the ct action is executed,
because this is a new connection, hardware will need to be send this back
to software, on chain 0, to execute the first filter again in software.
The dst port needs to be reverted otherwise it won't re-match the old
dst port in the first filter. Because of that, currently mlx5 driver will
reject offloading the above action ct rule.
This series adds support for hardware partially executing a filter's action list,
and letting tc software continue processing in the specific action instance
where hardware left off (in the above case after the "action pedit ex munge tcp
dport... of the first rule") allowing support for scenarios such as the above.

Currently, CT misses restore the missed chain on the tc skb extension so
tc will continue from the relevant chain. Instead, restore the CT action's
miss cookie on the extension, which will instruct tc to continue from the
this specific CT action instance on the relevant filter's action list.
Map the CT action's miss_cookie to a new miss object (ACT_MISS), and use
this miss mapping instead of the current chain miss object (CHAIN_MISS)
for CT action misses.
To restore this new miss mapping value, add a RX restore rule for each
such mapping value.

For drivers to support partial offload of a filter's action list,
add support for action miss to specify an action instance to
continue from in sw.
CT action in particular can't be fully offloaded, as new connections
need to be handled in software. This imposes other limitations on
the actions that can be offloaded together with the CT action, such
as packet modifications.
Assign each action on a filter's action list a unique miss_cookie
which drivers can then use to fill action_miss part of the tc skb
extension. On getting back this miss_cookie, find the action
instance with relevant cookie and continue classifying from there.

pull-request: ieee802154-next 2023-02-20
Miquel Raynal build upon his earlier work and introduced two new
features into the ieee802154 stack. Beaconing to announce existing
PAN's and passive scanning to discover the beacons and associated
PAN's. The matching changes to the userspace configuration tool
have been posted as well and will be released together with the
kernel release.
Arnd Bergmann and Dmitry Torokhov worked on converting the
at86rf230 and cc2520 drivers away from the unused platform_data
usage and towards the new gpiod API. (I had to add a revert as
Dmitry found a regression on an already pushed tree on my side).
Changes since v1 (pull request 2023-02-02)
- Netlink API extack and NLA_POLICY* usage as suggested by Jakub
- Removed always true condition found by kernel test robot
- Simplify device removal with running background job for scanning
- Fix problems with beacon sending in some cases by using the MLME

The call "skb_copy_from_linear_data(skb, inl + 1, spc)" triggers a FORTIFY
memcpy() warning on ppc64 platform:
In function ‘fortify_memcpy_chk’,
inlined from ‘skb_copy_from_linear_data’ at ./include/linux/skbuff.h:4029:2,

attribute warning: detected write beyond size of field (1st parameter); maybe use struct_group()?
[-Werror=attribute-warning]
513 | __write_overflow_field(p_size_field, size);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Same behaviour on x86 you can get if you use "__always_inline" instead of
"inline" for skb_copy_from_linear_data() in skbuff.h
The call here copies data into inlined tx destricptor, which has 104
bytes (MAX_INLINE) space for data payload. In this case "spc" is known
in compile-time but the destination is used with hidden knowledge
(real structure of destination is different from that the compiler
can see). That cause the fortify warning because compiler can check
bounds, but the real bounds are different. "spc" can't be bigger than
64 bytes (MLX4_INLINE_ALIGN), so the data can always fit into inlined
tx descriptor. The fact that "inl" points into inlined tx descriptor is
determined earlier in mlx4_en_xmit().
Avoid confusing the compiler with "inl + 1" constructions to get to past
the inl header by introducing a flexible array "data" to the struct so
that the compiler can see that we are not dealing with an array of inl
structs, but rather, arbitrary data following the structure. There are
no changes to the structure layout reported by pahole, and the resulting
machine code is actually smaller.

Only three minor changes: a cross-platform series from Mike Rapoport to
consolidate asm/agp.h between architectures, and a correctness change
for __generic_cmpxchg_local() from Matt Evans.

About a quarter of the changes are for 32-bit arm, mostly filling in
device support for existing machines and adding minor cleanups, mostly
for Qualcomm and Samsung based machines.
Two new 32-bit SoCs are added, both are quad-core Cortex-A7 chips from
Rockchips that have been around for a while but were lacking kernel
support so far: RV1126 is a Vision SoC with an NPU and is used in the
Edgeble Neural Compute Module 2(Neu2) board, while RK3128 is design for
TV boxes and so far only comes with a dts for its refernece design.
The other 32-bit boards that were added are two ASpeed AST2600 based BMC
boards, the Microchip sam9x60_curiosity development board (Armv5 based!),
the Enclustra PE1 FPGA-SoM baseboard, and a few more boards for i.MX53
and i.MX6ULL.
On the RISC-V side, there are fewer patches, but a total of ten new
single-board computers based on variations of the Allwinner D1/T113 chip,
plus one more board based on Microchip Polarfire.
As usual, arm64 has by far the most changes here, with over 700 non-merge
changesets, among them over 400 alone for Qualcomm. The newly added SoCs
this time are all recent high-end embedded SoCs for various markets,
each on comes with support for its reference board:
- Qualcomm SM8550 (Snapdragon 8 Gen 2) for mobile phones
- Qualcomm QDU1000/QRU1000 5G RAN platform
- Rockchips RK3588/RK3588s for tablets, chromebooks and SBCs
- TI J784S4 for industrial and automotive applications
In total, there are 46 new arm64 machines:
- Reference platforms for each of the five new SoCs
- Three Amlogic based development boards
- Six embedded machines based on NXP i.MX8MM and i.MX8MP
- The Mediatek mt7986a based Banana Pi R3 router
- Six tablets based on Qualcomm MSM8916 (Snapdragon 410),
SM6115 (Snapdragon 662) and SM8250 (Snapdragon 865)
- Two LTE dongles, also based on MSM8916
- Seven mobile phones, based on Qualcomm MSM8953 (Snapdragon 610),
SDM450 and SDM632
- Three chromebooks based on Qualcomm SC7280 (Snapdragon 7c)
- Nine development boards based on Rockchips RK3588, RK3568,
RK3566 and RK3328.
- Five development machines based on TI K3 (AM642/AM654/AM68/AM69)
The cleanup of dtc warnings continues across all platforms, adding
to the total number of changes.

As usual, this branch contains all the patches to enable options
for newly added device drivers in the 32-bit and 64-bit defconfig
files.
I have sorted the files according to the changes to Kconfig files,
to make it easier to check what has changed compared to the 'make
savedefconfig' output.
The most notable change this time is a series from Mark Brown
to add a 'virtconfig' target for arm64, which is for the moment
the same as the 'defconfig' target but disables all the top-level
SoC specific options in order to have a smaller and faster
kernel build.

Pull btrfs updates from David Sterba:
"The usual mix of performance improvements and new features.
The core change is reworking how checksums are processed, with
followup cleanups and simplifications. There are two minor changes in
block layer and iomap code.
Features:
- block group allocation class heuristics:
- pack files by size (up to 128k, up to 8M, more) to avoid
fragmentation in block groups, assuming that file size and life
time is correlated, in particular this may help during balance
- with tracepoints and extensible in the future
Performance:
- send: cache directory utimes and only emit the command when
necessary
- speedup up to 10x
- smaller final stream produced (no redundant utimes commands
issued)
- compatibility not affected
- fiemap: skip backref checks for shared leaves
- speedup 3x on sample filesystem with all leaves shared (e.g. on
snapshots)
- micro optimized b-tree key lookup, speedup in metadata operations
(sample benchmark: fs_mark +10% of files/sec)
Core changes:
- change where checksumming is done in the io path:
- checksum and read repair does verification at lower layer
- cascaded cleanups and simplifications
- raid56 refactoring and cleanups
Fixes:
- sysfs: make sure that a run-time change of a feature is correctly
tracked by the feature files
- scrub: better reporting of tree block errors
Other:
- locally enable -Wmaybe-uninitialized after fixing all warnings
- misc cleanups, spelling fixes
Other code:
- block: export bio_split_rw
- iomap: remove IOMAP_F_ZONE_APPEND"

"Support for auditing decisions regarding fanotify permission events"
* tag 'fsnotify_for_v6.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs:
fanotify,audit: Allow audit to use the full permission event response
fanotify: define struct members to hold response decision context
fanotify: Ensure consistent variable type for response
Fix the longstanding implementation limitation that fsverity was only
supported when the Merkle tree block size, filesystem block size, and
PAGE_SIZE were all equal. Specifically, add support for Merkle tree
block sizes less than PAGE_SIZE, and make ext4 support fsverity on
filesystems where the filesystem block size is less than PAGE_SIZE.
Effectively, this means that fsverity can now be used on systems with
non-4K pages, at least on ext4. These changes have been tested using
the verity group of xfstests, newly updated to cover the new code paths.
Also update fs/verity/ to support verifying data from large folios.
There's also a similar patch for fs/crypto/, to support decrypting data
from large folios, which I'm including in this pull request to avoid a
merge conflict between the fscrypt and fsverity branches.
There will be a merge conflict in fs/buffer.c with some of the foliation
work in the mm tree. Please use the merge resolution from linux-next.

Pull fsverity updates from Eric Biggers:
"Fix the longstanding implementation limitation that fsverity was only
supported when the Merkle tree block size, filesystem block size, and
PAGE_SIZE were all equal.
Specifically, add support for Merkle tree block sizes less than
PAGE_SIZE, and make ext4 support fsverity on filesystems where the
filesystem block size is less than PAGE_SIZE.
Effectively, this means that fsverity can now be used on systems with
non-4K pages, at least on ext4. These changes have been tested using
the verity group of xfstests, newly updated to cover the new code
paths.
Also update fs/verity/ to support verifying data from large folios.
There's also a similar patch for fs/crypto/, to support decrypting
data from large folios, which I'm including in here to avoid a merge
conflict between the fscrypt and fsverity branches"
