      net_sched: do not broadcast RTM_GETTFILTER result · fa59b27c
      Eric Dumazet authored
      There are two ways to get tc filters from kernel to user space.
      
      1) Full dump (tc_dump_tfilter())
      2) RTM_GETTFILTER to get one precise filter, reducing overhead.
      
      The second operation is unfortunately broadcasting its result,
      polluting "tc monitor" users.
      
      This patch makes sure only the requester gets the result, using
      netlink_unicast() instead of rtnetlink_send()
      
      Jamal cooked an iproute2 patch to implement "tc filter get" operation,
      but other user space libraries already use RTM_GETTFILTER when a single
      filter is queried, instead of dumping all filters.

      strparser: Propagate correct error code in strp_recv() · 6d3a4c40
      Geert Uytterhoeven authored
      With m68k-linux-gnu-gcc-4.1:
      
          net/strparser/strparser.c: In function ‘strp_recv’:
          net/strparser/strparser.c:98: warning: ‘err’ may be used uninitialized in this function
      
      Pass "len" (which is an error code when negative) instead of the
      uninitialized "err" variable to fix this.
      
      Fixes: 43a0c675 ("strparser: Stream parser for messages")
