linux-toradex.git/net/ipv4/ip_tunnel_core.c, branch v3.11.1 Linux kernel for Apalis and Colibri modules ip_tunnel: Do not use inner ip-header-id for tunnel ip-header-id. 2013-08-13T23:52:50+00:00 Pravin B Shelar pshelar@nicira.com 2013-08-13T08:41:06+00:00 4221f40513233fa8edeef7fc82e44163fde03b9b Using inner-id for tunnel id is not safe in some rare cases. E.g. packets coming from multiple sources entering same tunnel can have same id. Therefore on tunnel packet receive we could have packets from two different stream but with same source and dst IP with same ip-id which could confuse ip packet reassembly. Following patch reverts optimization from commit 490ab08127 (IP_GRE: Fix IP-Identification.)

Using inner-id for tunnel id is not safe in some rare cases.
E.g. packets coming from multiple sources entering same tunnel
can have same id. Therefore on tunnel packet receive we
could have packets from two different stream but with same
source and dst IP with same ip-id which could confuse ip packet
reassembly.

Following patch reverts optimization from commit
490ab08127 (IP_GRE: Fix IP-Identification.)
