* | [NETFILTER]: Fix outgoing redirects to loopbackPatrick McHardy2006-02-191-11/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | When redirecting an outgoing packet to loopback, it keeps the original conntrack reference and information from the outgoing path, which falsely triggers the check for DNAT on input and the dst_entry is released to trigger rerouting. ip_route_input refuses to route the packet because it has a local source address and it is dropped. Look at the packet itself to dermine if it was NATed. Also fix a missing inversion that causes unneccesary xfrm lookups. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ICMP errors are only SNATed when their source matches the source of the connection they are related to, otherwise the source address is not changed. This creates problems with ICMP frag. required messages originating from a router behind the NAT, if private IPs are used the packet has a good change of getting dropped on the path to its destination. Always NAT ICMP errors similar to the original connection. Based on report by Al Viro. 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_finishPatrick McHardy2006-02-154-11/+24
| | | | | | | | | | | | | | | 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.

* [NETFILTER]: Fix xfrm lookup after SNATPatrick McHardy2006-02-152-3/+44
| | | | | | | | | | | | | | | | | | | | To find out if a packet needs to be handled by IPsec after SNAT, packets are currently rerouted in POST_ROUTING and a new xfrm lookup is done. This breaks SNAT of non-unicast packets to non-local addresses because the packet is routed as incoming packet and no neighbour entry is bound to the dst_entry. In general, it seems to be a bad idea to replace the dst_entry after the packet was already sent to the output routine because its state might not match what's expected. This patch changes the xfrm lookup in POST_ROUTING to re-use the original dst_entry without routing the packet again. This means no policy routing can be used for transport mode transforms (which keep the original route) when packets are SNATed to match the policy, but it looks like the best we can do for now.

* [IPSEC]: Fix strange IPsec freeze.Herbert Xu2006-02-131-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem discovered and initial patch by Olaf Kirch: there's a problem with IPsec that has been bugging some of our users for the last couple of kernel revs. Every now and then, IPsec will freeze the machine completely. This is with openswan user land, and with kernels up to and including 2.6.16-rc2. I managed to debug this a little, and what happens is that we end up looping in xfrm_lookup, and never get out. With a bit of debug printks added, I can this happening: ip_route_output_flow calls xfrm_lookup xfrm_find_bundle returns NULL (apparently we're in the middle of negotiating a new SA or something) We therefore call xfrm_tmpl_resolve. This returns EAGAIN We go to sleep, waiting for a policy update. Then we loop back to the top Apparently, the dst_orig that was passed into xfrm_lookup has been dropped from the routing table (obsolete=2) This leads to the endless loop, because we now create a new bundle, check the new bundle and find it's stale (stale_bundle -> xfrm_bundle_ok -> dst_check() return 0) People have been testing with the patch below, which seems to fix the problem partially. They still see connection hangs however (things only clear up when they start a new ping or new ssh). So the patch is obvsiouly not sufficient, and something else seems to go wrong. I'm grateful for any hints you may have... I suggest that we simply bail out always. If the dst decides to die on us later on, the packet will be dropped anyway. So there is no great urgency to retry here. Once we have the proper resolution queueing, we can then do the retry again.

Destination socket is used in the place where it was meant to be source socket, so that now overrun is never sent to user netlink sockets, when it should be, and it even can be set on kernel socket, which results in complete deadlock of rtnetlink. Suggested fix is to restore status quo passing source socket as additional argument to netlink_attachskb(). A little explanation: overrun is set on a socket, when it failed to receive some message and sender of this messages does not or even have no way to handle this error. This happens in two cases: 1. when kernel sends something. Kernel never retransmits and cannot wait for buffer space. 2. when user sends a broadcast and the message was not delivered to some recipients.

Either is sufficient to overwrite arbitrary amounts of kernel memory. I really hate adding the same check to all 4 versions of do_replace(), but the code is duplicate...

| * [NETFILTER]: ULOG/nfnetlink_log: Use better default value for 'nlbufsiz'Holger Eitzenberger2006-02-043-3/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Performance tests showed that ULOG may fail on heavy loaded systems because of failed order-N allocations (N >= 1). The default value of 4096 is not optimal in the sense that it actually allocates _two_ contigous physical pages. Reasoning: ULOG uses alloc_skb(), which adds another ~300 bytes for skb_shared_info. This patch sets the default value to NLMSG_GOODSIZE and adds some documentation at the top.
