Re: [PATCH net-next v4 0/7] gtp: misc improvements

Hi Pablo, This is v4 of the GTP improvements. Compared to v3 it contains mostly smallish naming and spelling fixes. It also drops the documentation patch, Harald did a better job with the documentation and the some things I described do not yet match the implementation. I'll readd the relevant parts with a follow up series. This series lays the groundwork for removing the socket references from the GTP netdevice by removing duplicate code and simplifying the logic on some code paths. It slighly changes the GTP genl API by making the socket parameters optional (though one of them is still required). The removal of the socket references will break the 1:1 releation between GTP netdevice and GTP socket that prevents us to support multiple VRFs with overlaping IP addresse spaces attached to the same GTP-U entity (needed for multi APN support, comming a follow up series). Pablo found a socket hold problem in v2. In order to solve that I had to switch the socket references from the struct socket to the internal struct sock. This should have no functionl impact, but we can now hang on to the reference without blocking user space from closing the GTP socket. v3->v4: * drop the documentation patch * spelling fixes * pass nlattr instead of genl_info into gtp_find_dev, makes the code slightly more compact and readable v2->v3: * add documentation to explain the goal of all these changes * incorporate review comments * switch from struct socket to struct sock Regards Andreas -- Andreas Schultz (7): gtp: switch from struct socket to struct sock for the GTP sockets gtp: make GTP sockets in gtp_newlink optional gtp: merge gtp_get_net and gtp_genl_find_dev gtp: consolidate gtp socket rx path gtp: unify genl_find_pdp and prepare for per socket lookup gtp: consolidate pdp context destruction into helper gtp: add socket to pdp context drivers/net/gtp.c | 543 +++++++++++++++++++++++++++--------------------------- 1 file changed, 269 insertions(+), 274 deletions(-) -- 2.10.2
