* | sctp: try harder to figure out address family when checking wildcardsVlad Yasevich2008-10-01
| | | | | | | | | | | | | | | | | | | | | | sctp_is_any() function that is used to check for wildcard addresses only looks at the address itself to determine the address family. This function is used in the API to check the address passed in from the user. If the user simply zerroes out the sockaddr_storage and pass that in, we'll end up failing. So, let's try harder to determine the address family by also checking the socket if it's possible. Signed-off-by: Vlad Yasevich <vladislav.yasevich@hp.com>

* | tcp: Port redirection support for TCPKOVACS Krisztian2008-10-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current TCP code relies on the local port of the listening socket being the same as the destination address of the incoming connection. Port redirection used by many transparent proxying techniques obviously breaks this, so we have to store the original destination port address. This patch extends struct inet_request_sock and stores the incoming destination port value there. It also modifies the handshake code to use that value as the source port when sending reply packets.

* | ipv4: Make Netfilter's ip_route_me_harder() non-local address compatibleKOVACS Krisztian2008-10-01
| | | | | | | | | | | | | | | | | | | | | | Netfilter's ip_route_me_harder() tries to re-route packets either generated or re-routed by Netfilter. This patch changes ip_route_me_harder() to handle packets from non-locally-bound sockets with IP_TRANSPARENT set as local and to set the appropriate flowi flags when re-doing the routing lookup.

* | tcp: Handle TCP SYN+ACK/ACK/RST transparencyKOVACS Krisztian2008-10-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | ipv4: Make inet_sock.h independent of route.hKOVACS Krisztian2008-10-01

* | ipv4: Implement IP_TRANSPARENT socket optionKOVACS Krisztian2008-10-01
| | | | | | | | | | | | | | | | | | This patch introduces the IP_TRANSPARENT socket option: enabling that will make the IPv4 routing omit the non-local source address check on output.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | ipsec: Put dumpers on the dump listHerbert Xu2008-10-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

But GCC promotes "remaining" to unsigned in the test against sizeof(*nla) above. Therefore the test succeeds, and the nla_for_each_attr() may access memory outside the received buffer. A short example illustrating this point is here: #include <stdio.h> main(void) { printf("%d\n", -1 >= sizeof(int)); } ...which prints "1". This patch adds a cast in front of the sizeof so that GCC will make a signed comparison and fix the illegal memory dereference. With the patch applied, there is no kmemcheck report.

This patch totally cleans up the rate control API to remove the requirement to include internal headers outside of net/mac80211/. There's one internal use in the PID algorithm left for mesh networking, we'll have to figure out a way to clean that one up and decide how to do the peer link evaluation, possibly independent of the rate control algorithm or via new API. Additionally, ath9k is left using the cross-inclusion hack for now, we will add new API where necessary to make this work properly, but right now I'm not expert enough to do it.

* | ipsec: Fix xfrm_state_walk raceHerbert Xu2008-09-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As discovered by Timo Teräs, the currently xfrm_state_walk scheme is racy because if a second dump finishes before the first, we may free xfrm states that the first dump would walk over later. This patch fixes this by storing the dumps in a list in order to calculate the correct completion counter which cures this problem. I've expanded netlink_cb in order to accomodate the extra state related to this. It shouldn't be a big deal since netlink_cb is kmalloced for each dump and we're just increasing it by 4 or 8 bytes.
