2008-10-01tcp: Handle TCP SYN+ACK/ACK/RST transparencyKOVACS Krisztian
The TCP stack sends out SYN+ACK/ACK/RST reply packets in response to incoming packets. The non-local source address check on output bites us again, as replies for transparently redirected traffic won't have a chance to leave the node. This patch selectively sets the FLOWI_FLAG_ANYSRC flag when doing the route lookup for those replies. Transparent replies are enabled if the listening socket has the transparent socket flag set.

2008-10-01ipv4: Conditionally enable transparent flow flag when connectingKOVACS Krisztian
Set FLOWI_FLAG_ANYSRC in flowi->flags if the socket has the transparent socket option set. This way we selectively enable certain connections with non-local source addresses to be routed. Signed-off-by: KOVACS Krisztian <hidden@sch.bme.hu> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-10-01ipv4: Make inet_sock.h independent of route.hKOVACS Krisztian
inet_iif() in inet_sock.h requires route.h. Since users of inet_iif() usually require other route.h functionality anyway this patch moves inet_iif() to route.h. Signed-off-by: KOVACS Krisztian <hidden@sch.bme.hu> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-10-01ipv4: Allow binding to non-local addresses if IP_TRANSPARENT is setTóth László Attila
Setting IP_TRANSPARENT is not really useful without allowing non-local binds for the socket. To make user-space code simpler we allow these binds even if IP_TRANSPARENT is set but IP_FREEBIND is not.

2008-10-01ipv4: Implement IP_TRANSPARENT socket optionKOVACS Krisztian
This patch introduces the IP_TRANSPARENT socket option: enabling that will make the IPv4 routing omit the non-local source address check on output. Setting IP_TRANSPARENT requires NET_ADMIN capability. Signed-off-by: KOVACS Krisztian <hidden@sch.bme.hu> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-10-01ipv4: Loosen source address check on IPv4 outputJulian Anastasov
ip_route_output() contains a check to make sure that no flows with non-local source IP addresses are routed. This obviously makes using such addresses impossible. This patch introduces a flowi flag which makes omitting this check possible. The new flag provides a way of handling transparent and non-transparent connections differently.

2008-10-01net: BUG instead of corrupting memory in pskb_expand_headHerbert Xu

2008-10-01ipsec: Put dumpers on the dump listHerbert Xu
Herbert Xu came up with the idea and the original patch to make xfrm_state dump list contain also dumpers: As it is we go to extraordinary lengths to ensure that states don't go away while dumpers go to sleep. It's much easier if we just put the dumpers themselves on the list since they can't go away while they're going. I've also changed the order of addition on new states to prevent a never-ending dump. Timo Teräs improved the patch to apply cleanly to latest tree, modified iteration code to be more readable by using a common struct for entries in the list, implemented the same idea for xfrm_policy dumping and moved the af_key specific "last" entry caching to af_key.

2008-10-01dm mpath: add missing path switching lockingChandra Seetharaman
Moving the path activation to workqueue along with scsi_dh patches introduced a race. It is due to the fact that the current_pgpath (in the multipath data structure) can be modified if changes happen in any of the paths leading to the lun. If the changes lead to current_pgpath being set to NULL, then it leads to the invalid access which results in the panic below. This patch fixes that by storing the pgpath to activate in the multipath data structure and properly protecting it. Note that if activate_path is called twice in succession with different pgpath, with the second one being called before the first one is done, then activate path will be called twice for the second pgpath, which is fine.

2008-10-01net: add skb_recycle_check() to enable netdriver skb recyclingLennert Buytenhek
This patch adds skb_recycle_check(), which can be used by a network driver after transmitting an skb to check whether this skb can be recycled as a receive buffer. skb_recycle_check() checks that the skb is not shared or cloned, and that it is linear and its head portion large enough (as determined by the driver) to be recycled as a receive buffer. If these conditions are met, it does any necessary reference count dropping and cleans up the skbuff as if it just came from __alloc_skb().

The patch below populates the active_mtu field with a MTU of 2k. It also zeros the struct, so that any new additions to it will return 0.

2008-09-30x86, vmi: fix broken LDT accessZachary Amsden
This one took a long time to rear up because LDT usage is not very common, but the bug is quite serious. It got introduced along with another bug, already fixed, by 75b8bb3e56ca09a467fbbe5229bc68627f7445be After investigating a JRE failure, I found this bug was introduced a long time ago, and had already managed to survive another bugfix which occurred on the same line. The result is a total failure of the JRE due to LDT selectors not working properly.
