* uapi: fix linux/if_pppol2tp.h userspace compilation errorsDmitry V. Levin2020-06-03
| | | | | | | | | | | | | | | | | | | | | | | | commit a725eb15db80643a160310ed6bcfd6c5a6c907f2 upstream. Because of <linux/libc-compat.h> interface limitations, <netinet/in.h> provided by libc cannot be included after <linux/in.h>, therefore any header that includes <netinet/in.h> cannot be included after <linux/in.h>. Change uapi/linux/l2tp.h, the last uapi header that includes <netinet/in.h>, to include <linux/in.h> and <linux/in6.h> instead of <netinet/in.h> and use __SOCK_SIZE__ instead of sizeof(struct sockaddr) the same way as uapi/linux/in.h does, to fix linux/if_pppol2tp.h userspace compilation errors like this: In file included from /usr/include/linux/l2tp.h:12:0, from /usr/include/linux/if_pppol2tp.h:21, /usr/include/netinet/in.h:31:8: error: redefinition of 'struct in_addr' Fixes: 47c3e7783be4 ("net: l2tp: deprecate PPPOL2TP_MSG_* in favour of L2TP_MSG_*") Signed-off-by: Dmitry V.

* l2tp : multicast notification to the registered listenersBill Hong2014-12-31
| | | | | | | | | | | | | | Previously l2tp module did not provide any means for the user space to get notified when tunnels/sessions are added/modified/deleted. This change contains the following - create a multicast group for the listeners to register. - notify the registered listeners when the tunnels/sessions are created/modified/deleted.
