[PATCH 1/2] ip_gre: fix error path when erspan_rcv failed

2017-12-14 Thread Haishuang Yan
When erspan_rcv call return PACKET_REJECT, we shoudn't call ipgre_rcv to process packets again, instead send icmp unreachable message in error path. Fixes: 84e54fe0a5ea ("gre: introduce native tunnel support for ERSPAN") Cc: William Tu Signed-off-by: Haishuang Yan --- net/ipv4/ip_gre.c | 2 ++
