test_btf_dump fails when run with O=, because it needs to access source
files and assumes they live in ./progs/, which is not the case in this
scenario.
Fix by instructing kselftest to copy btf_dump_test_case_*.c files to the
test directory. Since kselftest does not preserve directory structure,
adjust the test to look in ./progs/ and then in ./.

test_cgroup_storage fails on s390 with an assertion failure: packets are
dropped when they shouldn't. The problem is that BPF_DW packet count is
accessed as BPF_W with an offset of 0, which is not correct on
big-endian machines.
Since the point of this test is not to verify narrow loads/stores,
simply use BPF_DW when working with packet counts.

fail on s390 because of endianness issue: the 4 IP address bytes are
loaded as a word and compared with a constant, but the value of this

is not the case right now.

Change BPF selftest test_xdp_vlan.sh to (default) use generic XDP.
This selftest was created together with a fix for generic XDP, in commit
297249569932 ("net: fix generic XDP to handle if eth header was
mangled"). And was suppose to catch if generic XDP was broken again.
The tests are using veth and assumed that veth driver didn't support
native driver XDP, thus it used the (ip link set) 'xdp' attach that fell
back to generic-XDP. But veth gained native-XDP support in 948d4f214fde
("veth: Add driver XDP"), which caused this test script to use
native-XDP.

'flow offload' expression should not offload flows that will be subject
to ipsec, but it does.
This results in a connectivity blackhole for the affected flows -- first
packets will go through (offload happens after established state is
reached), but all remaining ones bypass ipsec encryption and are thus
discarded by the peer.
This can be worked around by adding "rt ipsec exists accept"
before the 'flow offload' rule matches.
This test case will fail, support for such flows is added in
next patch.

On my laptop most memcg kselftests were being skipped because it claimed
cgroup v2 hierarchy wasn't mounted, but this isn't correct. Instead, it
seems current systemd HEAD mounts it with the name "cgroup2" instead of
"cgroup":
% grep cgroup /proc/mounts
cgroup2 /sys/fs/cgroup cgroup2 rw,nosuid,nodev,noexec,relatime,nsdelegate 0 0
I can't think of a reason to need to check fs_spec explicitly
since it's arbitrary, so we can just rely on fs_vfstype.
After these changes, `make TARGETS=cgroup kselftest` actually runs the
cgroup v2 tests in more cases.

the config changes are restored when the script exits.
Note this functionality needs to keep in sync with:
- dynamic_debug input/output formatting
- functions affected by set_dynamic_debug()

Add a skip() message function that stops the test, logs an explanation,
and sets the "skip" return code (4).
Before loading a livepatch self-test kernel module, first verify that
we've built and installed it by running a 'modprobe --dry-run'. This
should catch a few environment issues, including !CONFIG_LIVEPATCH and
!CONFIG_TEST_LIVEPATCH. In these cases, exit gracefully with the new
skip() function.

The TC filters used in the test do not work with veth devices because the
outer Ethertype is 802.1Q and not IPv4. The test passes with mlxsw
netdevs since the hardware always looks at "The first Ethertype that
does not point to either: VLAN, CNTAG or configurable Ethertype".
Fix this by matching on the VLAN ID instead, but on the ingress side.
The reason why this is not performed at egress is explained in the
commit cited below.

The test did not enable IPv4 forwarding during its setup phase, which
causes the test to fail on machines where IPv4 forwarding is disabled.

"sendmsg6: rewrite IP & port (C)" fails on s390, because the code in
sendmsg_v6_prog() assumes that (ctx->user_ip6[0] & 0xFFFF) refers to
leading IPv6 address digits, which is not the case on big-endian
machines.
Since checking bitwise operations doesn't seem to be the point of the
test, replace two short comparisons with a single int comparison.

Add test which sends some data with MSG_MORE and then
closes the socket (never calling send without MSG_MORE).
This should make sure we clean up open records correctly.
