| | | | | | | | | | | | | Bridge would crash because of uninitailized timer if STP is used and device was inserted into a bridge before bridge was up. This got introduced when the delayed port checking was added. Fix is to not enable STP on port unless bridge is up.

* | [IPSEC]: Kill post_input hook and do NAT-T in esp_input directlyHerbert Xu2006-02-272-97/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The only reason post_input exists at all is that it gives us the potential to adjust the checksums incrementally in future which we ought to do. However, after thinking about it for a bit we can adjust the checksums without using this post_input stuff at all. The crucial point is that only the inner-most NAT-T SA needs to be considered when adjusting checksums. What's more, the checksum adjustment comes down to a single u32 due to the linearity of IP checksums. We just happen to have a spare u32 lying around in our skb structure :) When ip_summed is set to CHECKSUM_NONE on input, the value of skb->csum is currently unused. All we have to do is to make that the checksum adjustment and voila, there goes all the post_input and decap structures! I've left in the decap data structures for now since it's intricately woven into the sec_path stuff. We can kill them later too.

* [NET] ethernet: Fix first packet goes out with MAC 00:00:00:00:00:00Jamal Hadi Salim2006-02-231-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When you turn off ARP on a netdevice then the first packet always goes out with a dstMAC of all zeroes. This is because the first packet is used to resolve ARP entries. Even though the ARP entry may be resolved (I tried by setting a static ARP entry for a host i was pinging from), it gets overwritten by virtue of having the netdevice disabling ARP. Subsequent packets go out fine with correct dstMAC address (which may be why people have ignored reporting this issue). To cut the story short: the culprit code is in net/ethernet/eth.c::eth_header() ---- /* * Anyway, the loopback-device should never use this function... */ if (dev->flags & (IFF_LOOPBACK|IFF_NOARP)) { memset(eth->h_dest, 0, dev->addr_len); return ETH_HLEN; } if(daddr) { memcpy(eth->h_dest,daddr,dev->addr_len); return ETH_HLEN; } ---- Note how the h_dest is being reset when device has IFF_NOARP. As a note: All devices including loopback pass a daddr. loopback in fact passes a 0 all the time ;-> This means i can delete the check totaly or i can remove the IFF_NOARP Alexey says: -------------------- I think, it was me who did this crap. It was so long ago I do not remember why it was made. I remember some troubles with dummy device. It tried to resolve addresses, apparently, without success and generated errors instead of blackholing. I think the problem was eventually solved at neighbour level. After some thinking I suspect the deletion of this chunk could change behaviour of some parts which do not use neighbour cache f.e. packet socket. I think safer approach would be to move this chunk after if (daddr). And the possibility to remove this completely could be analyzed later. -------------------- Patch updated with Alexey's safer suggestions.

* [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.

| * [Bluetooth] Fix NULL pointer dereferences of the HCI socketMarcel Holtmann2006-02-131-2/+8
| | | | | | | | | | | | | | | | | | This patch fixes the two NULL pointer dereferences found by the sfuzz tool from Ilja van Sprundel. The first one was a call of getsockname() for an unbound socket and the second was calling accept() while this operation isn't implemented for the HCI socket interface.

| | | | | | | | | | | | | | | | | | This patch reduces the default L2CAP MTU for all RFCOMM connections from 1024 to 1013 to improve the interoperability with some broken RFCOMM implementations. To make this more flexible the L2CAP MTU becomes also a module parameter and so it can changed at runtime. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
