Pull networking fixes from Jakub Kicinski:
"Including fixes from netfilter, Bluetooth and WPAN.
No outstanding fixes / investigations at this time.
Current release - new code bugs:
- eth: fbnic: revert HWMON support, it doesn't work at all and revert
is similar size as the fixes
Previous releases - regressions:
- tcp: allow a connection when sk_max_ack_backlog is zero
- tls: fix tls_sw_sendmsg error handling
Previous releases - always broken:
- netdev netlink family:
- prevent accessing NAPI instances from another namespace
- don't dump Tx and uninitialized NAPIs
- net: sysctl: avoid using current->nsproxy, fix null-deref if task
is exiting and stick to opener's netns
- sched: sch_cake: add bounds checks to host bulk flow fairness
counts
Misc:
- annual cleanup of inactive maintainers"

Start from resetting the middle queue because edge cases

Most of our tests use rtnetlink to read device stats, so they
don't expose the drivers much to paths in which device stats
are read under RCU. Add tests which hammer profcs reads to
make sure drivers:
- don't sleep while reporting stats,
- can handle parallel reads,
- can handle device going down while reading.
Set ifname on the env class in NetDrvEnv, we already do that
in NetDrvEpEnv.

The script tries to resolve the path to the current toolchain using
realpath, which fails in case it's not installed, and since it's run
under -e, it doesn't have the opportunity to display a help message.
Let's detect the absence of the required toolchain before running that
command and provide a friendlier message when this happens.

Latest versions of GCC BPF use C23 standard by default. This causes
compilation errors in vmlinux.h due to bool types declarations.
Add -std=gnu11 to BPF_CFLAGS and CFLAGS. This aligns with the version
of the standard used when building the kernel currently [1].
For more details see the discussions at [2] and [3].

Add coverage of the hwcaps for the 2024 dpISA extensions to the hwcap
test.
We don't actually test SIGILL generation for CMPBR since the need to
branch makes it a pain to generate and the SIGILL detection would be
unreliable anyway. Since this should be very unusual we provide a stub
function rather than supporting a missing test.
The sigill functions aren't well sorted in the file so the ordering is a
bit random.

Test a more realistic usage pattern, and one with heavy contention, in order to
actually exercise ntsync's internal synchronization.
This test has several threads in a tight loop acquiring a mutex, modifying some
shared data, and then releasing the mutex. At the end we check if the data is
consistent.

A few recently added packetdrill tests that are known time sensitive
(e.g., because testing timestamping) occasionally fail in debug mode:
https://netdev.bots.linux.dev/contest.html?executor=vmksft-packetdrill-dbg
These failures are well understood. Correctness of the tests is
verified in non-debug mode. Continue running in debug mode also, to
keep coverage with debug instrumentation.
But, only in debug mode, mark these tests with well understood
timing issues as XFAIL (known failing) rather than FAIL when failing.
Introduce an allow list xfail_list with known cases.
Expand the ktap infrastructure with XFAIL support.

Currently, when we run the BPF selftests with the following command:
make -C tools/testing/selftests TARGETS=bpf SKIP_TARGETS=""
The command generates untracked files and directories with make version
less than 4.4:
'''
Untracked files:
(use "git add <file>..." to include in what will be committed)
tools/testing/selftests/bpfFEATURE-DUMP.selftests
tools/testing/selftests/bpffeature/
'''
We lost slash after word "bpf". The reason is slash appending code is as
follow:
'''
OUTPUT := $(OUTPUT)/
$(eval include ../../../build/Makefile.feature)
OUTPUT := $(patsubst %/,%,$(OUTPUT))
'''
This way of assigning values to OUTPUT will never be effective for the
variable OUTPUT provided via the command argument [1] and BPF makefile
is called from parent Makfile(tools/testing/selftests/Makefile) like:
'''
all:
...
$(MAKE) OUTPUT=$$BUILD_TARGET -C $$TARGET
'''
According to GNU make, we can use override Directive to fix this issue [2].

After previous change rshift >= 32 is no longer allowed.
Modify the test to use 31, the test doesn't seem to send
any traffic so the exact value shouldn't matter.

Add a test which checks that the kstkesp field in /proc/pid/stat can be
read for all threads of a coredumping process.
For full details including the motivation for this test and how it works,

Pull networking fixes from Jakub Kicinski:
"Including fixes from wireles and netfilter.
Nothing major here. Over the last two weeks we gathered only around
two-thirds of our normal weekly fix count, but delaying sending these
until -rc7 seemed like a really bad idea.
AFAIK we have no bugs under investigation. One or two reverts for
stuff for which we haven't gotten a proper fix will likely come in the
next PR.
Current release - fix to a fix:
- netfilter: nft_set_hash: unaligned atomic read on struct
nft_set_ext
- eth: gve: trigger RX NAPI instead of TX NAPI in gve_xsk_wakeup
Previous releases - regressions:
- net: reenable NETIF_F_IPV6_CSUM offload for BIG TCP packets
- mptcp:
- fix sleeping rcvmsg sleeping forever after bad recvbuffer adjust
- fix TCP options overflow
- prevent excessive coalescing on receive, fix throughput
- net: fix memory leak in tcp_conn_request() if map insertion fails
- wifi: cw1200: fix potential NULL dereference after conversion to
GPIO descriptors
- phy: micrel: dynamically control external clock of KSZ PHY, fix
suspend behavior
Previous releases - always broken:
- af_packet: fix VLAN handling with MSG_PEEK
- net: restrict SO_REUSEPORT to inet sockets
- netdev-genl: avoid empty messages in NAPI get
- dsa: microchip: fix set_ageing_time function on KSZ9477 and LAN937X
- eth:
- gve: XDP fixes around transmit, queue wakeup etc.

Constify the following API:
struct device *device_find_child(struct device *dev, void *data,
int (*match)(struct device *dev, void *data));
To :
struct device *device_find_child(struct device *dev, const void *data,
device_match_t match);
typedef int (*device_match_t)(struct device *dev, const void *data);
with the following reasons:
- Protect caller's match data @*data which is for comparison and lookup
and the API does not actually need to modify @*data.
- Make the API's parameters (@match)() and @data have the same type as
all of other device finding APIs (bus|class|driver)_find_device().
- All kinds of existing device match functions can be directly taken
as the API's argument, they were exported by driver core.
Constify the API and adapt for various existing usages.
BTW, various subsystem changes are squashed into this commit to meet
'git bisect' requirement, and this commit has the minimal and simplest
changes to complement squashing shortcoming, and that may bring extra
code improvement.

In cxl_dvsec_rr_decode() the pci driver expects to retrieve a cxlds,
struct cxl_dev_state, from the driver_data field of struct device.
While that works for Type 3, drivers for Type 1/2 devices may not
put a cxlds in the driver_data field.
In preparation for supporting Type 1/2 devices, replace parameter
'struct device' with 'struct cxl_dev_state' in cxl_dvsec_rr_decode().
Remove the unused parameter 'cxl_port' in cxl_dvsec_rr_decode().

assert that we are able to do this in a test to ensure that we do not

Commit 82c1f13de315 ("selftests/bpf: Add more stats into veristat")
introduced new stats, added by default in the CSV output, that were not
added to parse_stat_value, used in parse_stats_csv which is used in
comparison mode. Thus it broke comparison mode altogether making it fail
with "Unrecognized stat #7" and EINVAL.
One quirk is that PROG_TYPE and ATTACH_TYPE have been transformed to
strings using libbpf_bpf_prog_type_str and libbpf_bpf_attach_type_str
respectively. Since we might not want to compare those string values, we
just skip the parsing in this patch. We might want to translate it back
to the enum value or compare the string value directly.
