Introduce SKIP_LLVM makefile variable that allows to avoid using llvm
dependencies when building BPF selftests. This is different from
existing feature-llvm, as the latter is a result of automatic detection
and should not be set by user explicitly.
Avoiding llvm dependencies could be useful for environments that do not
have them, given that as of now llvm dependencies are required only by
jit_disasm_helpers.c.

It was located in conntrack_vrf.sh because that already had the VRF bits.
Lets not add to this and move it to nft_fib.sh where this belongs.
No functional changes for the subtest intended.
The subtest is limited, it only covered 'fib oif'
(route output interface query) when the incoming interface is part
of a VRF.
Next we can extend it to cover 'fib type' for VRFs and also check fib
results when there is an unrelated VRF in same netns.

fib can either lookup the interface id/name of the output interface that
would be used for the given address, or it can check for the type of the
address according to the fib, e.g. local, unicast, multicast and so on.
This can be used to e.g. make a locally configured address only reachable
through its interface.
Example: given eth0:10.1.1.1 and eth1:10.1.2.1 then 'fib daddr type' for
10.1.1.1 arriving on eth1 will be 'local', but 'fib daddr . iif type' is
expected to return 'unicast', whereas 'fib daddr' and 'fib daddr . iif'
are expected to indicate 'local' if such a packet arrives on eth0.
So far nft_fib.sh only covered oif/oifname, not type.
Repeat tests both with default and a policy (ip rule) based setup.
Also try to run all remaining tests even if a subtest has failed.

representation
Pipapo supports a more compact '4 bit group' format that is chosen when
the memory needed for the default exceeds a threshold (2mb).
Add coverage for those code paths, the existing tests use small sets that
are handled by the default representation.
This comes with a test script run-time increase, but I think its ok:
normal: 2m35s -> 3m9s
debug: 3m24s -> 5m29s (with KSFT_MACHINE_SLOW=yes).

This test reproduces a scenario where HFSC queue length and backlog accounting
can become inconsistent when a peek operation triggers a dequeue and possible
drop before the parent qdisc updates its counters. The test sets up a DRR root
qdisc with an HFSC class, netem, and blackhole children, and uses Scapy to
inject a packet. It helps to verify that HFSC correctly tracks qlen and backlog
even when packets are dropped during peek-induced dequeue.

Allow the user to specify a physical interface through the $CANIF
environment variable. Add a $BITRATE environment variable set with a
default value of 500000.
If $CANIF is omitted or if it starts with vcan (e.g. vcan1), the test
will use the virtual can interface type. Otherwise, it will assume
that the provided interface is a physical can interface.
For example:
CANIF=can1 BITRATE=1000000 ./test_raw_filter.sh
will run set the can1 interface with a bitrate of one million and run
the tests on it.

Tests for the can subsystem have been in the can-tests repository[1] so
far. Start moving the tests to kernel selftests by importing the current
tst-filter test. The test is now named test_raw_filter and is substantially
updated to be more aligned with the kernel selftests, follow the coding
style, and simplify the validation of received CAN frames. We also include
documentation of the test design. The test verifies that the single filters
on raw CAN sockets work as expected.
We intend to import more tests from can-tests and add additional test cases
in the future. The goal of moving the CAN selftests into the tree is to
align the tests more closely with the kernel, improve testing of CAN in
general, and to simplify running the tests automatically in the various
kernel CI systems.

Usage of longjmp() was added to ensure that teardown is always run in
commit 63e6b2a42342 ("selftests/harness: Run TEARDOWN for ASSERT failures")
However instead of calling longjmp() to the teardown handler it is easier to
just call the teardown handler directly from __bail().
Any potential duplicate teardown invocations are harmless as the actual
handler will only ever be executed once since
commit fff37bd32c76 ("selftests/harness: Fix fixture teardown").
Additionally this removes a incompatibility with nolibc,
which does not support setjmp()/longjmp().

Currently, the sbi_pmu_test continues if the exception type is illegal
instruction because access to hpmcounter will generate that. However
illegal instruction exception may occur due to the other reasons
which should result in test assertion.
Use the stval to decode the exact type of instructions and which csrs are
being accessed if it is csr access instructions. Assert in all cases
except if it is a csr access instructions that access valid PMU related
registers.
Take this opportunity to remove the CSR_CYCLEH reference as the test is

Cover three recent cases:
1. missing ops locking for the lowers during netdev_sync_lower_features
2. missing locking for dev_set_promiscuity (plus netdev_ops_assert_locked
with a comment on why/when it's needed)
3. rcu lock during team_change_rx_flags
Verified that each one triggers when the respective fix is reverted.
Not sure about the placement, but since it all relies on teaming,
added to the teaming directory.
One ugly bit is that I add NETIF_F_LRO to netdevsim; there is no way
to trigger netdev_sync_lower_features without it.

existing split BTF and add info to it; ensure that such BTF can be
created and handled by searching within it, dumping/comparing to expected.
