      net/mlx5: Fix the order of fc_stats cleanup · b1b9f97a
      Gavi Teitz authored
      Previously, mlx5_cleanup_fc_stats() would cleanup the flow counter
      pool beofre releasing all the counters to it, which would result in
      flow counter bulks not getting freed. Resolve this by changing the
      order in which elements of fc_stats are cleaned up, so that the flow
      counter pool is cleaned up after all the counters are released.
      
      Also move cleanup actions for freeing the bulk query memory and
      destroying the idr to the end of mlx5_cleanup_fc_stats().

      net/mlx5e: Fix deallocation of non-fully init encap entries · 3c140dd5
      Vlad Buslov authored
      Recent rtnl lock dependency refactoring changed encap entry attach code to
      insert encap entry to hash table before it was fully initialized in order
      to allow concurrent tc users to wait on completion for encap entry to
      finish initialization. That change required all the users of encap entry to
      obtain reference to it first and for caller that creates encap to put
      reference to it on error, instead of freeing the entry memory directly.
      However, releasing reference to such encap entry that wasn't fully
      initialized causes NULL pointer dereference in
      mlx5e_rep_encap_entry_detach() which expects e->out_dev to be set and encap
      to be attached to nhe:

      To fix the issue, set e->compl_result to positive value after encap was
      initialized successfully. Check e->compl_result value in
      mlx5e_encap_dealloc() and only detach and dealloc encap if the value is
      positive.

      net/mlx5e: RX, Handle CQE with error at the earliest stage · 0a35ab3e
      Saeed Mahameed authored
      Just to be aligned with the MPWQE handlers, handle RX WQE with error
      for legacy RQs in the top RX handlers, just before calling skb_from_cqe().
      
      CQE error handling will now be called at the same stage regardless of
      the RQ type or netdev mode NIC, Representor, IPoIB, etc ..
      
      This will be useful for down stream patch to improve error CQE
      handling.

      sctp: remove net sctp.x_enable working as a global switch · 2f757634
      Xin Long authored
      The netns sctp feature flags shouldn't work as a global switch,
      which is mostly like a firewall/netfilter's job. Also, it will
      break asoc as it discard or accept chunks incorrectly when net
      sctp.x_enable is changed after the asoc is created.
      
      Since each type of chunk's processing function will check the
      corresp asoc's feature flag, this 'global switch' should be
      removed, and net sctp.x_enable will only work as the default
      feature flags for the future sctp sockets/endpoints.

      tc-testing: concurrency: wrap piped rule update commands · 14b54ac4
      Vlad Buslov authored
      Concurrent tests use several commands to update rules in parallel: 'find'
      prints names of batch files in tmp directory and pipes result to 'xargs'
      which runs instance of tc per batch file in parallel. This breaks when used
      with ns plugin that adds 'ip netns exec $NS' prefix to the command, which
      causes only first command in pipe to be executed in namespace:

      tc-testing: use dedicated DUMMY interface name for dummy dev · c11a99e7
      Vlad Buslov authored
      A lot of tests reuse $DEV1 veth name for naming dummy device. This causes
      problem when tdc is invoked without specifying a test group and tries to
      execute all tests. In this case tdc instantiates ns plugin, which creates
      veth pair once before running tests. However, if any of the tests that
      reuse $DEV1 run before test that depend on ns plugin, it will delete $DEV1
      as a part of teardown section:

      keys: Fix description size · 555df336
      David Howells authored
      The maximum key description size is 4095.  Commit f771fde8 ("keys:
      Simplify key description management") inadvertantly reduced that to 255
      and made sizes between 256 and 4095 work weirdly, and any size whereby
      size & 255 == 0 would cause an assertion in __key_link_begin() at the
      following line:
      
      	BUG_ON(index_key->desc_len == 0);
      
      This can be fixed by simply increasing the size of desc_len in struct
      keyring_index_key to a u16.
      
      Note the argument length test in keyutils only checked empty
      descriptions and descriptions with a size around the limit (ie.  4095)
      and not for all the values in between, so it missed this.  This has been
      addressed and
      
      	https://git.kernel.org/pub/scm/linux/kernel/git/dhowells/keyutils.git/commit/?id=066bf56807c26cd3045a25f355b34c1d8a20a5aa
      
      now exhaustively tests all possible lengths of type, description and
      payload and then some.
      
      The assertion failure looks something like:
