      selftests: mptcp: simplify pm_nl_change_endpoint · bccefb76
      Geliang Tang authored 
      This patch simplified pm_nl_change_endpoint(), using id-based address
lookups only. And dropped the fragile way of parsing 'addr' and 'id'
from the output of pm_nl_show_endpoints().

      selftests: mptcp: increase timeout to 20 minutes · d17b968b
      Matthieu Baerts authored 
      With the increase number of tests, one CI instance, using a debug kernel
config and not recent hardware, takes around 10 minutes to execute the
slowest MPTCP test: mptcp_join.sh.

Even if most CIs don't take that long to execute these tests --
typically max 10 minutes to run all selftests -- it will help some of
them if the timeout is increased.

The timeout could be disabled but it is always good to have an extra
safeguard, just in case.

Please note that on slow public CIs with kernel debug settings, it has
been observed it can easily take up to 45 minutes to execute all tests
in this very slow environment with other jobs running in parallel.
The slowest test, mptcp_join.sh takes ~30 minutes in this case.

In such environments, the selftests timeout set in the 'settings' file
is disabled because this environment is known as being exceptionnally
slow. It has been decided not to take such exceptional environments into
account and set the timeout to 20min.

====================
bpf-next 2022-02-17

We've added 29 non-merge commits during the last 8 day(s) which contain
a total of 34 files changed, 1502 insertions(+), 524 deletions(-).

The main changes are:

1) Add BTFGen support to bpftool which allows to use CO-RE in kernels without
   BTF info, from Mauricio Vásquez, Rafael David Tinoco, Lorenzo Fontana and
   Leonardo Di Donato. (Details: https://lpc.events/event/11/contributions/948/)

2) Prepare light skeleton to be used in both kernel module and user space
   and convert bpf_preload.ko to use light skeleton, from Alexei Starovoitov.

3) Rework bpftool's versioning scheme and align with libbpf's version number;
   also add linked libbpf version info to "bpftool version", from Quentin Monnet.

4) Add minimal C++ specific additions to bpftool's skeleton codegen to
   facilitate use of C skeletons in C++ applications, from Andrii Nakryiko.

5) Add BPF verifier sanity check whether relative offset on kfunc calls overflows
   desc->imm and reject the BPF program if the case, from Hou Tao.

6) Fix libbpf to use a dynamically allocated buffer for netlink messages to
   avoid receiving truncated messages on some archs, from Toke Høiland-Jørgensen.

7) Various follow-up fixes to the JIT bpf_prog_pack allocator, from Song Liu.

8) Various BPF selftest and vmtest.sh fixes, from Yucong Sun.

9) Fix bpftool pretty print handling on dumping map keys/values when no BTF
   is available, from Jiri Olsa and Yinjun Zhang.

10) Extend XDP frags selftest to check for invalid length, from Lorenzo Bianconi.
