ipv6: use net->rt_genid to check dst validity

2012-09-18T19:57:03Z

IPv6 dst should take care of rt_genid too. When a xfrm policy is inserted or deleted, all dst should be invalidated. To force the validation, dst entries should be created with ->obsolete set to DST_OBSOLETE_FORCE_CHK. This was already the case for all functions calling ip6_dst_alloc(), except for ip6_rt_copy(). As a consequence, we can remove the specific code in inet6_connection_sock. Signed-off-by: Nicolas Dichtel Signed-off-by: David S. Miller

ipv6: Store route neighbour in rt6_info struct.

2012-07-05T09:41:58Z

This makes for a simplified conversion away from dst_get_neighbour*(). All code outside of ipv6 will use neigh lookups via dst_neigh_lookup*(). Signed-off-by: David S. Miller

Revert "ipv6: Prevent access to uninitialized fib_table_hash via /proc/net/ipv6_route"

2012-06-16T08:12:19Z

This reverts commit 2a0c451ade8e1783c5d453948289e4a978d417c9. It causes crashes, because now ip6_null_entry is used before it is initialized. Signed-off-by: David S. Miller

Conflicts: net/ipv6/route.c This deals with a merge conflict between the net-next addition of the inetpeer network namespace ops, and Thomas Graf's bug fix in 2a0c451ade8e1783c5d453948289e4a978d417c9 which makes sure we don't register /proc/net/ipv6_route before it is actually safe to do so.

ipv6: Prevent access to uninitialized fib_table_hash via /proc/net/ipv6_route

2012-06-15T22:30:15Z

/proc/net/ipv6_route reflects the contents of fib_table_hash. The proc handler is installed in ip6_route_net_init() whereas fib_table_hash is allocated in fib6_net_init() _after_ the proc handler has been installed. This opens up a short time frame to access fib_table_hash with its pants down. fib6_init() as a whole can't be moved to an earlier position as it also registers the rtnetlink message handlers which should be registered at the end. Therefore split it into fib6_init() which is run early and fib6_init_late() to register the rtnetlink message handlers. Signed-off-by: Thomas Graf Reviewed-by: Neil Horman Signed-off-by: David S.

inet: Add inetpeer tree roots to the FIB tables.

inet: Hide route peer accesses behind helpers.

2012-06-11T09:08:47Z

We encode the pointer(s) into an unsigned long with one state bit. The state bit is used so we can store the inetpeer tree root to use when resolving the peer later. Later the peer roots will be per-FIB table, and this change works to facilitate that. Signed-off-by: David S. Miller

ipv6: clean up rt6_clean_expires

2012-04-18T02:31:59Z

Functionally, this change is a NOP. Semantically, rt6_clean_expires() wants to do rt->dst.from = NULL instead of rt->dst.expires = 0. It is clearing the RTF_EXPIRES flag, so the union is going to be treated as a pointer (dst.from) not a long (dst.expires). Signed-off-by: Jiri Bohac Signed-off-by: David S. Miller

ipv6: fix rt6_update_expires

2012-04-18T02:31:51Z

Commit 1716a961 (ipv6: fix problem with expired dst cache) broke PMTU discovery. rt6_update_expires() calls dst_set_expires(), which only updates dst->expires if it has not been set previously (expires == 0) or if the new expires is earlier than the current dst->expires. rt6_update_expires() needs to zero rt->dst.expires, otherwise it will contain ivalid data left over from rt->dst.from and will confuse dst_set_expires().
