Seems like 4d1b62986125 ("selftests/bpf: Convert few tests to light skeleton.")
and 704e2beba23c ("selftests/bpf: Test ringbuf mmap read-only and read-write
restrictions") were done independently on bpf and bpf-next trees and are in
conflict with each other, despite a clean merge. Fix fetching of ringbuf's
map_fd to use light skeleton properly.

According to a comment in commit 99513cfa16c6 ("selftest: Fixes for
icmp_redirect test") the test "IPv6: mtu exception plus redirect" is
expected to fail, because of a bug in the IPv6 logic that hasn't been
fixed yet apparently.
We should probably consider this failure as an "expected failure",
therefore change the script to return XFAIL for that particular test and
also report the total amount of expected failures at the end of the run.

and

The missing entry is because the 2nd packet hits a tuple collusion and the

Without this modification, we were often displaying this error messages:
FAIL: Could not even run loopback test
But $ret could have been set to a non 0 value in many different cases:
- net.mptcp.enabled=0 is not working as expected
- setsockopt(..., TCP_ULP, "mptcp", ...) is allowed
- ping between each netns are failing
- tests between ns1 as a receiver and ns>1 are failing
- other tests not involving ns1 as a receiver are failing
So not only for the loopback test.
Now a clearer message, including the time it took to run all tests, is
displayed.

This patch added a new argument "-C" for the mptcp_join.sh script to set
the sysctl checksum_enabled to 1 in ns1 and ns2 to enable the data
checksum.
In chk_join_nr, check the counter of the mib for the data checksum.
Also added a new argument "-S" for the mptcp_join.sh script to start the
test cases that verify the checksum handshake:
* Sender and listener both have checksums off
* Sender and listener both have checksums on
* Sender checksums off, listener checksums on
* Sender checksums on, listener checksums off
The output looks like this:
01 checksum test 0 0 sum[ ok ] - csum [ ok ]
02 checksum test 1 1 sum[ ok ] - csum [ ok ]
03 checksum test 0 1 sum[ ok ] - csum [ ok ]
04 checksum test 1 0 sum[ ok ] - csum [ ok ]
05 no JOIN syn[ ok ] - synack[ ok ] - ack[ ok ]
sum[ ok ] - csum [ ok ]
06 single subflow, limited by client syn[ ok ] - synack[ ok ] - ack[ ok ]
sum[ ok ] - csum [ ok ]

migrate_reuseport.c selftest relies on having TCP_FASTOPEN_CONNECT defined in
system-wide netinet/tcp.h. Selftests can use up-to-date uapi/linux/tcp.h, but
that one doesn't have SOL_TCP. So instead of switching everything to uapi
header, add #define for TCP_FASTOPEN_CONNECT to fix the build.

Somehow test_progs.h was being included by the existing rule:
/test_progs*
This is bad because:
1) test_progs.h is a checked in file
2) grep-like tools like ripgrep[0] respect gitignore and
test_progs.h was being hidden from searches

Previously, if rst2man caught errors, then these would be ignored and
the output file would be written anyway. This would allow developers to
introduce regressions in the docs comments in the BPF headers.
Additionally, even if you instruct rst2man to fail out, it will still
write out to the destination target file, so if you ran the tests twice
in a row it would always pass. Use a temporary file for the initial run
to ensure that if rst2man fails out under "--strict" mode, subsequent
runs will not automatically pass.

LLVM upstream commit https://reviews.llvm.org/D102712 made some changes
to bpf relocations to make them llvm linker lld friendly. The scope of
existing relocations R_BPF_64_{64,32} is narrowed and new relocations
R_BPF_64_{ABS32,ABS64,NODYLD32} are introduced.
Let us add some documentation about llvm bpf relocations so people can
understand how to resolve them properly in their respective tools.

targets low level tracing primitives. bpf_helpers.h is a better fit.

Add a bpf selftest for new helper xdp_redirect_map_multi(). In this
test there are 3 forward groups and 1 exclude group. The test will
redirect each interface's packets to all the interfaces in the forward
group, and exclude the interface in exclude map.
Two maps (DEVMAP, DEVMAP_HASH) and two xdp modes (generic, drive) will
be tested. XDP egress program will also be tested by setting pkt src MAC
to egress interface's MAC address.
For more test details, you can find it in the test script. Here is
the test result.

Turn ony libbpf 1.0 mode. Fix all the explicit IS_ERR checks that now will be
broken because libbpf returns NULL on error (and sets errno). Fix
ASSERT_OK_PTR and ASSERT_ERR_PTR to work for both old mode and new modes and
use them throughout selftests. This is trivial to do by using
libbpf_get_error() API that all libbpf users are supposed to use, instead of
IS_ERR checks.
A bunch of checks also did explicit -1 comparison for various fd-returning
APIs. Such checks are replaced with >= 0 or < 0 cases.
There were also few misuses of bpf_object__find_map_by_name() in test_maps.
Those are fixed in this patch as well.

Add bpf selftests and extend existing ones for a new function
bpf_lookup_and_delete_elem() for (percpu) hash and (percpu) LRU hash map
types.
In test_lru_map and test_maps we add an element, lookup_and_delete it,
then check whether it's deleted.
The newly added lookup_and_delete prog tests practically do the same
thing but additionally use a BPF program to change the value of the
element for LRU maps.

In the commit referenced below, a check was added to devlink_lib that
asserts the existence of a devlink device referenced by $DEVLINK_DEV.
Unfortunately, several netdevsim tests point DEVLINK_DEV at a device that
does not exist at the time that devlink_lib is sourced. Thus these tests
spuriously fail.
Fix this by introducing an override. By setting DEVLINK_DEV to an empty
string, the user declares their intention to handle DEVLINK_DEV management
on their own.
In all netdevsim tests that use devlink_lib and set DEVLINK_DEV, set
instead an empty DEVLINK_DEV just before sourcing devlink_lib, and set it
to the correct value right afterwards.

Several tests do not set some ports down as part of their cleanup(),
resulting in IPv6 link-local addresses and associated routes not being
deleted.
These leaks were found using a BPF tool that monitors ASIC resources.
Solve this by setting the ports down at the end of the tests.

To check how many routes are installed in hardware, the test runs "ip
route" and greps for "offload", which includes routes with state
"offload_failed".
Till now, this wrong check was not found because after one failure in
route insertion, the driver moved to "abort" mode, which means that user
cannot try to add more routes.
The previous patch removed the abort mechanism and now failed routes are
counted as offloaded.
Fix this by not considering routes with "offload_failed" flag as
offloaded.

This extends the existing setsockopt test case to also check for cmsg
timestamps.
mptcp_connect will abort/fail if the setockopt was passed but the
timestamp cmsg isn't present after successful recvmsg().

When there is no devlink device, the following command will return:
$ devlink -j dev show
{dev:{}}
This will cause IndexError when trying to access the first element
in dev of this json dataset. Use the kselftest framework skip code
to skip this test in this case.
Example output with this change:
# selftests: net: devlink_port_split.py
# no devlink device was found, test skipped
ok 7 selftests: net: devlink_port_split.py # SKIP
