      net: add dev_uc_sync_multiple() and dev_mc_sync_multiple() api · 4cd729b0
      Vlad Yasevich authored
      The current implementation of dev_uc_sync/unsync() assumes that there is
      a strict 1-to-1 relationship between the source and destination of the sync.
      In other words, once an address has been synced to a destination device, it
      will not be synced to any other device through the sync API.
      However, there are some virtual devices that aggreate a number of lower
      devices and need to sync addresses to all of them.  The current
      API falls short there.
      
      This patch introduces a new dev_uc_sync_multiple() api that can be called
      in the above circumstances and allows sync to work for every invocation.

      net: sctp: minor: make sctp_ep_common's member 'dead' a bool · 0022d2dd
      Daniel Borkmann authored
      Since dead only holds two states (0,1), make it a bool instead
      of a 'char', which is more appropriate for its purpose.

      net: sctp: remove sctp_ep_common struct member 'malloced' · ff2266cd
      Daniel Borkmann authored
      There is actually no need to keep this member in the structure, because
      after init it's always 1 anyway, thus always kfree called. This seems to
      be an ancient leftover from the very initial implementation from 2.5
      times. Only in case the initialization of an association fails, we leave
      base.malloced as 0, but we nevertheless kfree it in the error path in
      sctp_association_new().

      vxlan: don't bypass encapsulation for multi- and broadcasts · ab09a6d0
      Mike Rapoport authored
      The multicast and broadcast packets may have RTCF_LOCAL set in rt_flags
      and therefore will be sent out bypassing encapsulation. This breaks
      delivery of packets sent to the vxlan multicast group.
      Disabling encapsulation bypass for multicasts and broadcasts fixes the
      issue.
