      rtnetlink: always put IFLA_LINK for links with a link-netnsid · feadc4b6
      Sabrina Dubroca authored
      Currently, nla_put_iflink() doesn't put the IFLA_LINK attribute when
      iflink == ifindex.
      
      In some cases, a device can be created in a different netns with the
      same ifindex as its parent. That device will not dump its IFLA_LINK
      attribute, which can confuse some userspace software that expects it.
      For example, if the last ifindex created in init_net and foo are both
      8, these commands will trigger the issue:
      
          ip link add parent type dummy                   # ifindex 9
          ip link add link parent netns foo type macvlan  # ifindex 9 in ns foo
      
      So, in case a device puts the IFLA_LINK_NETNSID attribute in a dump,
      always put the IFLA_LINK attribute as well.
      
      Thanks to Dan Winship for analyzing the original OpenShift bug down to
      the missing netlink attribute.

      tcp: fix retrans timestamp on passive Fast Open · cd736d8b
      Yuchung Cheng authored
      Commit c7d13c8f ("tcp: properly track retry time on
      passive Fast Open") sets the start of SYNACK retransmission
      time on passive Fast Open in "retrans_stamp". However the
      timestamp is not reset upon the handshake has completed. As a
      result, future data packet retransmission may not update it in
      tcp_retransmit_skb(). This may lead to socket aborting earlier
      unexpectedly by retransmits_timed_out() since retrans_stamp remains
      the SYNACK rtx time.
      
      This bug only manifests on passive TFO sender that a) suffered
      SYNACK timeout and then b) stalls on very first loss recovery. Any
      successful loss recovery would reset the timestamp to avoid this
      issue.

      bpf: test ref bit from data path and add new tests for syscall path · d2baab62
      Daniel Borkmann authored
      The test_lru_map is relying on marking the LRU map entry via regular
      BPF map lookup from system call side. This is basically for simplicity
      reasons. Given we fixed marking entries in that case, the test needs
      to be fixed as well. Here we add a small drop-in replacement to retain
      existing behavior for the tests by marking out of the BPF program and
      transferring the retrieved value out via temporary map. This also adds
      new test cases to track the new behavior where two elements are marked,
      one via system call side and one via program side, where the next update
      then evicts the key looked up only from system call side.

      bpf, lru: avoid messing with eviction heuristics upon syscall lookup · 50b045a8
      Daniel Borkmann authored
      One of the biggest issues we face right now with picking LRU map over
      regular hash table is that a map walk out of user space, for example,
      to just dump the existing entries or to remove certain ones, will
      completely mess up LRU eviction heuristics and wrong entries such
      as just created ones will get evicted instead. The reason for this
      is that we mark an entry as "in use" via bpf_lru_node_set_ref() from
      system call lookup side as well. Thus upon walk, all entries are
      being marked, so information of actual least recently used ones
      are "lost".
      
      In case of Cilium where it can be used (besides others) as a BPF
      based connection tracker, this current behavior causes disruption
      upon control plane changes that need to walk the map from user space
      to evict certain entries. Discussion result from bpfconf [0] was that
      we should simply just remove marking from system call side as no
      good use case could be found where it's actually needed there.
      Therefore this patch removes marking for regular LRU and per-CPU
      flavor. If there ever should be a need in future, the behavior could
      be selected via map creation flag, but due to mentioned reason we
      avoid this here.

      bpf: add map_lookup_elem_sys_only for lookups from syscall side · c6110222
      Daniel Borkmann authored
      Add a callback map_lookup_elem_sys_only() that map implementations
      could use over map_lookup_elem() from system call side in case the
      map implementation needs to handle the latter differently than from
      the BPF data path. If map_lookup_elem_sys_only() is set, this will
      be preferred pick for map lookups out of user space. This hook is
      used in a follow-up fix for LRU map, but once development window
      opens, we can convert other map types from map_lookup_elem() (here,
      the one called upon BPF_MAP_LOOKUP_ELEM cmd is meant) over to use
      the callback to simplify and clean up the latter.
