Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

[NETFILTER]: Fix xfrm lookup in ip_route_me_harder/ip6_route_me_harder ip_route_me_harder doesn't use the port numbers of the xfrm lookup and uses ip_route_input for non-local addresses which doesn't do a xfrm lookup, ip6_route_me_harder doesn't do a xfrm lookup at all. Use xfrm_decode_session and do the lookup manually, make sure both only do the lookup if the packet hasn't been transformed already. Makeing sure the lookup only happens once needs a new field in the IP6CB, which exceeds the size of skb->cb. The size of skb->cb is increased to 48b. Apparently the IPv6 mobile extensions need some more room anyway. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>

[XFRM]: Fix SNAT-related crash in xfrm4_output_finish When a packet matching an IPsec policy is SNATed so it doesn't match any policy anymore it looses its xfrm bundle, which makes xfrm4_output_finish crash because of a NULL pointer dereference. This patch directs these packets to the original output path instead. Since the packets have already passed the POST_ROUTING hook, but need to start at the beginning of the original output path which includes another POST_ROUTING invocation, a flag is added to the IPCB to indicate that the packet was rerouted and doesn't need to pass the POST_ROUTING hook again.

ip: ip_ra_control() rcu fix commit 66018506e15b (ip: Router Alert RCU conversion) introduced RCU lookups to ip_call_ra_chain(). It missed proper deinit phase : When ip_ra_control() deletes an ip_ra_chain, it should make sure ip_call_ra_chain() users can not start to use socket during the rcu grace period. It should also delay the sock_put() after the grace period, or we risk a premature socket freeing and corruptions, as raw sockets are not rcu protected yet. This delay avoids using expensive atomic_inc_not_zero() in ip_call_ra_chain(). Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Several cpus send UDP frames to the same destination, hence use the same dst entry. This patch makes ip_append_data() eventually steal the refcount its callers had to take on the dst entry.

inet: Add ip_make_skb and ip_finish_skb This patch adds the helper ip_make_skb which is like ip_append_data and ip_push_pending_frames all rolled into one, except that it does not send the skb produced. The sending part is carried out by ip_send_skb, which the transport protocol can call after it has tweaked the skb. It is meant to be called in cases where corking is not used should have a one-to-one correspondence to sendmsg. This patch also adds the helper ip_finish_skb which is meant to be replace ip_push_pending_frames when corking is required. Previously the protocol stack would peek at the socket write queue and add its header to the first packet. With ip_finish_skb, the protocol stack can directly operate on the final skb instead, just like the non-corking case with ip_make_skb.

ipv4: Make Netfilter's ip_route_me_harder() non-local address compatible Netfilter's ip_route_me_harder() tries to re-route packets either generated or re-routed by Netfilter.

snmp: 64bit ipstats_mib for all arches /proc/net/snmp and /proc/net/netstat expose SNMP counters. Width of these counters is either 32 or 64 bits, depending on the size of "unsigned long" in kernel. This means user program parsing these files must already be prepared to deal with 64bit values, regardless of user program being 32 or 64 bit. This patch introduces 64bit snmp values for IPSTAT mib, where some counters can wrap pretty fast if they are 32bit wide. # netstat -s|egrep "InOctets|OutOctets" InOctets: 244068329096 OutOctets: 244069348848 Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.

inet: cleanup of local_port_range I noticed sysctl_local_port_range[] and its associated seqlock sysctl_local_port_range_lock were on separate cache lines. Moreover, sysctl_local_port_range[] was close to unrelated variables, highly modified, leading to cache misses. Moving these two variables in a structure can help data locality and moving this structure to read_mostly section helps sharing of this data among cpus. Cleanup of extern declarations (moved in include file where they belong), and use of inet_get_local_port_range() accessor instead of direct access to ports values.

net: gre: provide multicast mappings for ipv4 and ipv6 My commit 6d55cb91a0020ac0 (gre: fix hard header destination address checking) broke multicast. The reason is that ip_gre used to get ipgre_header() calls with zero destination if we have NOARP or multicast destination. Instead the actual target was decided at ipgre_tunnel_xmit() time based on per-protocol dissection. Instead of allowing the "abuse" of ->header() calls with invalid destination, this creates multicast mappings for ip_gre. This also fixes "ip neigh show nud noarp" to display the proper multicast mappings used by the gre device.

inet: rename some inet_sock fields In order to have better cache layouts of struct sock (separate zones for rx/tx paths), we need this preliminary patch. Goal is to transfert fields used at lookup time in the first read-mostly cache line (inside struct sock_common) and move sk_refcnt to a separate cache line (only written by rx path) This patch adds inet_ prefix to daddr, rcv_saddr, dport, num, saddr, sport and id fields. This allows a future patch to define these fields as macros, like sk_refcnt, without name clashes. Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.

We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it.

ip: fix mc_loop checks for tunnels with multicast outer addresses When we have L3 tunnels with different inner/outer families (i.e. IPV4/IPV6) which use a multicast address as the outer tunnel destination address, multicast packets will be loopbacked back to the sending socket even if IP*_MULTICAST_LOOP is set to disabled. The mc_loop flag is present in the family specific part of the socket (e.g. the IPv4 or IPv4 specific part). setsockopt sets the inner family mc_loop flag. When the packet is pushed through the L3 tunnel it will eventually be processed by the outer family which if different will check the flag in a different part of the socket then it was set.

netfilter: fix crashes in bridge netfilter caused by fragment jumps When fragments from bridge netfilter are passed to IPv4 or IPv6 conntrack and a reassembly queue with the same fragment key already exists from reassembling a similar packet received on a different device (f.i. with multicasted fragments), the reassembled packet might continue on a different codepath than where the head fragment originated. This can cause crashes in bridge netfilter when a fragment received on a non-bridge device (and thus with skb->nf_bridge == NULL) continues through the bridge netfilter code. Add a new reassembly identifier for packets originating from bridge netfilter and use it to put those packets in insolated queues.
