2009-02-18netfilter: Combine ipt_TTL and ip6t_HL sourceJan Engelhardt
Suggested by: James King <t.james.king@gmail.com> Similarly to commit c9fd49680954714473d6cbd2546d6ff120f96840, merge TTL and HL. Since HL does not depend on any IPv6-specific function, no new module dependencies would arise. With slight adjustments to the Kconfig help text.

2009-01-29gro: Avoid copying headers of unmerged packetsHerbert Xu
Unfortunately simplicity isn't always the best. The fraginfo interface turned out to be suboptimal. The problem was quite obvious. For every packet, we have to copy the headers from the frags structure into skb->head, even though for 99% of the packets this part is immediately thrown away after the merge. LRO didn't have this problem because it directly read the headers from the frags structure. This patch attempts to address this by creating an interface that allows GRO to access the headers in the first frag without having to copy it. Because all drivers that use frags place the headers in the first frag this optimisation should be enough. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

2009-01-27IPv6: Fix multicast routing bugs.Thomas Goff
This patch addresses the IPv6 multicast routing issues described below. It was tested with XORP 1.4/1.5 as the IPv6 PIM-SM routing daemon against FreeBSD peers. net/ipv6/ip6_input.c: - Don't try to forward link-local multicast packets. - Don't reset skb2->dev before calling ip6_mr_input() so packets can be identified as coming from the PIM register vif properly. net/ipv6/ip6mr.c: - Fix incoming PIM register messages processing: * The IPv6 pseudo-header should be included when checksumming PIM messages (RFC 4601 section 4.9; RFC 3973 section 4.7.1). * Packets decapsulated from PIM register messages should have skb->protocol ETH_P_IPV6. - Enable/disable IPv6 multicast forwarding on the corresponding interface when a routing daemon adds/removes a multicast virtual interface. - Remove incorrect skb_pull() to fix userspace signaling. - Enable/disable global IPv6 multicast forwarding when an IPv6 multicast routing socket is opened/closed. net/ipv6/route.c: - Don't use strict routing logic for packets decapsulated from PIM register messages (similar to disabling rp_filter for the IPv4 case).

2009-01-04ipv6: Fix sporadic sendmsg -EINVAL when sending to multicast groups.David S. Miller
Thanks to excellent diagnosis by Eduard Guzovsky. The core problem is that on a network with lots of active multicast traffic, the neighbour cache can fill up. If we try to allocate a new route and thus neighbour cache entry, the bog-standard GC attempt the neighbour layer does in ineffective because route entries hold a reference to the existing neighbour entries and GC can only liberate entries with no references. IPV4 already has a way to handle this, by doing a route cache GC in such situations (when neigh attach returns -ENOBUFS). So simply mimick this on the ipv6 side.

2008-12-10netns: ip6mr: enable namespace support in ipv6 multicast forwarding codeBenjamin Thery
This last patch makes the appropriate changes to use and propagate the network namespace where needed in IPv6 multicast forwarding code. This consists mainly in replacing all the remaining init_net occurences with current netns pointer retrieved from sockets, net devices or mfc6_caches depending on the routines' contexts. Some routines receive a new 'struct net' parameter to propagate the current netns: * ip6mr_get_route * ip6mr_cache_report * ip6mr_cache_find * ip6mr_cache_unresolved * mif6_add/mif6_delete * ip6mr_mfc_add/ip6mr_mfc_delete * ip6mr_reg_vif All the IPv6 multicast forwarding variables moved to struct netns_ipv6 by the previous patches are now referenced in the correct namespace. Changelog: ========== * Take into account the net associated to mfc6_cache when matching entries in mfc_unres_queue list. * Call mroute_clean_tables() in ip6mr_net_exit() to free memory allocated per-namespace. * Call dev_net_set() in ip6mr_reg_vif() to initialize dev->nd_net correctly.

This variable counts the number of unresolved cache entries queued in the list mfc_unres_queue. This list is kept global to all netns as the number of entries per namespace is limited to 10 (hardcoded in routine ip6mr_cache_unresolved). Entries belonging to different namespaces in mfc_unres_queue will be identified by matching the mfc_net member introduced previously in struct mfc6_cache. Keeping this list global to all netns, also allows us to keep a single timer (ipmr_expire_timer) to handle their expiration. In some places cache_resolve_queue_len value was tested for arming or deleting the timer. These tests were equivalent to testing mfc_unres_queue value instead and are replaced in this patch.
