      bpf: reduce runtime of test_sockmap tests · a18fda1a
      John Fastabend authored
      When test_sockmap was running outside of selftests and was not being
      run by build bots it was reasonable to spend significant amount of
      time running various tests. The number of tests is high because many
      different I/O iterators are run.
      
      However, now that test_sockmap is part of selftests rather than
      iterate through all I/O sides only test a minimal set of min/max
      values along with a few "normal" I/O ops. Also remove the long
      running tests. They can be run from other test frameworks on a regular
      cadence.
      
      This significanly reduces runtime of test_sockmap.
      
      Before:
      
      $ time sudo ./test_sockmap  > /dev/null
      
      real    4m47.521s
      user    0m0.370s
      sys     0m3.131s
      
      After:
      
      $ time sudo ./test_sockmap  > /dev/null
      
      real    0m0.514s
      user    0m0.104s
      sys     0m0.430s
      
      The CLI is still available for users that want to test the long
      running tests that do the larger send/recv tests.

      afs: Fix server record deletion · 66062592
      David Howells authored
      AFS server records get removed from the net->fs_servers tree when
      they're deleted, but not from the net->fs_addresses{4,6} lists, which
      can lead to an oops in afs_find_server() when a server record has been
      removed, for instance during rmmod.
      
      Fix this by deleting the record from the by-address lists before posting
      it for RCU destruction.
      
      The reason this hasn't been noticed before is that the fileserver keeps
      probing the local cache manager, thereby keeping the service record
      alive, so the oops would only happen when a fileserver eventually gets
      bored and stops pinging or if the module gets rmmod'd and a call comes
      in from the fileserver during the window between the server records
      being destroyed and the socket being closed.
      
      The oops looks something like:
      
        BUG: unable to handle kernel NULL pointer dereference at 000000000000001c
        ...
        Workqueue: kafsd afs_process_async_call [kafs]
