Pablo Neira Ayuso	e24258f4b1	genl: ix crash due to missing wrong prototype ... In function genl_socket_talk().	2014-01-21 18:09:17 +01:00
Pablo Neira Ayuso	fa4c10f4d7	genl: introduce genl_nlmsg_build_hdr and use it ... Add new generic function to build the netlink and genetlink headers.	2014-01-21 17:42:08 +01:00
Pablo Neira Ayuso	85dfd1ab09	call if_nametoindex out of the loop ... This uses a rtnetlink socket to look up for the interface index. This should speed up tunnel creation.	2014-01-21 14:23:30 +01:00
Pablo Neira Ayuso	b0ff3b67ef	provide simple genl library ... So we can get rid of genl-family-get.c to look up for the genetlink family ID.	2014-01-21 14:21:58 +01:00
Pablo Neira Ayuso	24782b2aa7	initial import ... Type `make' to compile kernel and userspace code. After that, you should see gtp.ko kernel module that you can insmod. The rudimentary userspace tools are: * gtp-link-add, that allows you to bring up the gtp0 device (via rtnetlink). * gtp-tunnel-add, to create tunnels via genetlink. This is also using using genl-family-get to obtain the (dynamic) genetlink family for the gtp operations, but that code is scheduled to be merged to gtp-tunnel-add. The tunneling code does not work yet, it triggers a crash, so it's been temporarily disabled. Original work from Harald Welte, I added the netlink interfaces and got this compiling.	2014-01-20 13:42:39 +01:00
