      selftests: mptcp: join: remove unused vars · 0a40e273
      Matthieu Baerts authored
      Shellcheck found that these variables were set but never used.
      
      Note that rndh is no longer prefixed with '0-' but it doesn't change
      anything.

      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.
