Andreas Schultz aschultz at tpip.netThe current linking of GTP network devices and GTP enabled sockets means that we can not have multiple VRF's per GTP socket. This series seperates the sockets from network device, makes sockets attached to GTP network device optional and adds a API function to enable GTP encapsulation on socket without having to create a new GTP device. It is still possible to use the old API. The network device attached socket is then used when no socket is specified on PDP context creation. During that work some smaller problems where found and fixes for them are included. v2 changes: * the socket that is hold by the pdp context has to be release in a rcu callback. Otherwise a stray GTP rx could end uo with an invalid socket. * accessing the skb->sk field in gtp_rx is invalid, that field has no been populated at that point * add dst_cache to speed up the routing Regards Andreas -- Andreas Schultz (18): gtp: add genl family modules alias gtp: clear DF bit on GTP packet tx gtp: make GTP sockets in gtp_newlink optional gtp: return error ptr in find pdp helpers gtp: unify genl_find_pdp and prepare for per socket lookup gtp: fix cross netns recv on gtp socket gtp: remove unnecessary rcu_read_lock gtp: consolidate pdp context destruction into helper gtp: use addr_hash when traversing pdp contexts gtp: add socket to pdp context gtp: consolidate gtp socket rx path gtp: let userspace handle packets for invalid tunnels gtp: replace netdev_dbg and KERN_DEBUG printk with pr_debug gtp: move TEID hash to per socket structure gtp: rename gtp hashtable helpers gtp: add genl cmd to enable GTP encapsulation on UDP socket gtp: add support to select a GTP socket during PDP context creation gtp: add dst_cache support drivers/net/gtp.c | 714 +++++++++++++++++++++++++++-------------------- include/uapi/linux/gtp.h | 4 + 2 files changed, 422 insertions(+), 296 deletions(-) -- 2.10.2
