This forces the use of a single socket for mroute programming, cache reports and, regarding ipmr, IGMP messages without Router Alert option reception. The present patches are aiming to send Netlink notifications in addition to the existing igmpmsg/mrt6msg to give user programs a way to handle cache reports in parallel with multiple sockets other than the mroute/mroute6 socket. Changes in v2: - Changed attributes naming from {IPMRA,IP6MRA}_CACHEREPORTA_* to {IPMRA,IP6MRA}_CREPORT_* - Improved packet data copy to handle non-linear packets in ipmr/ip6mr cache report Netlink notification creation - Added two rtnetlink groups with restricted-binding - Changed cache report notified groups from RTNL_{IPV4,IPV6}_MROUTE to the new restricted groups in ipmr/ip6mr Changes in v3: - Put message size calculation for {igmp,mrt6}msg_netlink_event in separate functions - Increased vif id attributes size from u8 to u32 Julien Gomes (4): rtnetlink: add NEWCACHEREPORT message type rtnetlink: add restricted rtnl groups for ipv4 and ipv6 mroute ipmr: add netlink notifications on igmpmsg cache reports ip6mr: add netlink notifications on mrt6msg cache reports include/uapi/linux/mroute.h | 12 +++++++ include/uapi/linux/mroute6.h | 12 +++++++ include/uapi/linux/rtnetlink.h | 7 +++++ net/core/rtnetlink.c | 13 ++++++++ net/ipv4/ipmr.c | 69 ++++++++++++++++++++++++++++++++++++++-- net/ipv6/ip6mr.c | 71 ++++++++++++++++++++++++++++++++++++++++-- security/selinux/nlmsgtab.c | 3 +- 7 files changed, 182 insertions(+), 5 deletions(-) -- 2.13.1
