      Merge branch 'sync_multiple' · 61f47132
      David S. Miller authored
      Vlad Yasevich says:
      
      ====================
      Current dev_[uc|mc]_addr_sync() API currently correctly syncs the
      addresses to the first device.  Any subsequent calls to sync will
      not do anything since the synched variable will be set.  This
      variable is used as an optimization to skip over addresses that have
      been synched.
      
      There are some devices (ex: team) that attempt to do the above.  There
      is other work in progress that needs to above to work corretly.
      
      The short series introduces dev_[uc|mc]_addr_synch_multiple() that
      allows multiple calls to sync to multiple different devices.  Original
      API is left alone and still has the limitation.

      team: Use new sync_multiple api to sync devices adressess. · 72b27032
      Vlad Yasevich authored
      Team drivers attempts to sync addresses to each of the port
      devices; however, the current api doesn't really perform the sync
      for any device after the first one.  Switch to using the new api
      that will actually sync the addresses to all ports.

      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.
