2013-06-13ip_tunnel: remove __net_init/exit from exported functionsEric Dumazet
If CONFIG_NET_NS is not set then __net_init is the same as __init and __net_exit is the same as __exit. These functions will be removed from memory after the module loads or is removed. Functions that are exported for use by other functions should never be labeled for removal. Bug introduced by commit c54419321455631079c ("GRE: Refactor GRE tunneling code.") Reported-by: Steinar H.

2013-03-26GRE: Refactor GRE tunneling code.Pravin B Shelar
Following patch refactors GRE code into ip tunneling code and GRE specific code. Common tunneling code is moved to ip_tunnel module. ip_tunnel module is written as generic library which can be used by different tunneling implementations. ip_tunnel module contains following components: - packet xmit and rcv generic code. xmit flow looks like (gre_xmit/ipip_xmit)->ip_tunnel_xmit->ip_local_out. - hash table of all devices. - lookup for tunnel devices. - control plane operations like device create, destroy, ioctl, netlink operations code. - registration for tunneling modules, like gre, ipip etc. - define single pcpu_tstats dev->tstats. - struct tnl_ptk_info added to pass parsed tunnel packet parameters. ipip.h header is renamed to ip_tunnel.h Signed-off-by: Pravin B Shelar <pshelar@nicira.com> Signed-off-by: David S.
