2010-10-21tproxy: kick out TIME_WAIT sockets in case a new connection comes in with ↵Balazs Scheidler
the same tuple Without tproxy redirections an incoming SYN kicks out conflicting TIME_WAIT sockets, in order to handle clients that reuse ports within the TIME_WAIT period. The same mechanism didn't work in case TProxy is involved in finding the proper socket, as the time_wait processing code looked up the listening socket assuming that the listener addr/port matches those of the established connection. This is not the case with TProxy as the listener addr/port is possibly changed with the tproxy rule.

2010-10-21smsc95xx: generate random MAC address once, not every ifupBernard Blackham
The smsc95xx driver currently generates a new random MAC address every time the interface is brought up. This makes it impossible to override using the standard `ifconfig hw ether` approach. Past patches tried to make the MAC address a module parameter or base it off the die ID, but it seems to me much simpler (and hopefully less controversial) to stick with the current random generation scheme, but allow the user to change the address. This patch does exactly that - it moves the random address generation from smsc95xx_reset() into smsc95xx_bind(), so that it is done once on module load, not on every ifup. The user can then override this using the standard mechanisms. Applies against 2.6.35 and linux-2.6 head. Signed-off-by: Bernard Blackham <b-omap@largestprime.net> Signed-off-by: David S.

2010-10-21ipvs: provide address family for debuggingJulian Anastasov
As skb->protocol is not valid in LOCAL_OUT add parameter for address family in packet debugging functions. Even if ports are not present in AH and ESP change them to use ip_vs_tcpudp_debug_packet to show at least valid addresses as before. This patch removes the last user of skb->protocol in IPVS.

2010-10-21ipvs: inherit forwarding method in backupJulian Anastasov
Connections in backup server should inherit the forwarding method from real server. It is a way to fix a problem where the forwarding method in backup connection is damaged by logical OR operation with the real server's connection flags. And the change is needed for setups where the backup server uses different forwarding method for the same real servers.

2010-10-21ipvs: changes for local clientJulian Anastasov
This patch deals with local client processing. Prefer LOCAL_OUT hook for scheduling connections from local clients. LOCAL_IN is still supported if the packets are not marked as processed in LOCAL_OUT. The idea to process requests in LOCAL_OUT is to alter conntrack reply before it is confirmed at POST_ROUTING. If the local requests are processed in LOCAL_IN the conntrack can not be updated and matching by state is impossible. Add the following handlers: - ip_vs_reply[46] at LOCAL_IN:99 to process replies from remote real servers to local clients. Now when both replies from remote real servers (ip_vs_reply*) and local real servers (ip_vs_local_reply*) are handled it is safe to remove the conn_out_get call from ip_vs_in because it does not support related ICMP packets. - ip_vs_local_request[46] at LOCAL_OUT:-98 to process requests from local client Handling in LOCAL_OUT causes some changes: - as skb->dev, skb->protocol and skb->pkt_type are not defined in LOCAL_OUT make sure we set skb->dev before calling icmpv6_send, prefer skb_dst(skb) for struct net and remove the skb->protocol checks from TUN transmitters.

2010-10-21ipvs: changes for local real serverJulian Anastasov
This patch deals with local real servers: - Add support for DNAT to local address (different real server port). It needs ip_vs_out hook in LOCAL_OUT for both families because skb->protocol is not set for locally generated packets and can not be used to set 'af'. - Skip packets in ip_vs_in marked with skb->ipvs_property because ip_vs_out processing can be executed in LOCAL_OUT but we still have the conn_out_get check in ip_vs_in. - Ignore packets with inet->nodefrag from local stack - Require skb_dst(skb) != NULL because we use it to get struct net - Add support for changing the route to local IPv4 stack after DNAT depending on the source address type. Local client sets output route and the remote client sets input route. It looks like IPv6 does not need such rerouting because the replies use addresses from initial incoming header, not from skb route. - All transmitters now have strict checks for the destination address type: redirect from non-local address to local real server requires NAT method, local address can not be used as source address when talking to remote real server. - Now LOCALNODE is not set explicitly as forwarding method in real server to allow the connections to provide correct forwarding method to the backup server. Not sure if this breaks tools that expect to see 'Local' real server type. If needed, this can be supported with new flag IP_VS_DEST_F_LOCAL. Now it should be possible connections in backup that lost their fwmark information during sync to be forwarded properly to their daddr, even if it is local address in the backup server. By this way backup could be used as real server for DR or TUN, for NAT there are some restrictions because tuple collisions in conntracks can create problems for the traffic. - Call ip_vs_dst_reset when destination is updated in case some real server IP type is changed between local and remote.

2010-10-21ipvs: move ip_route_me_harder for ICMPJulian Anastasov
Currently, ip_route_me_harder after ip_vs_out_icmp is called even if packet is not related to IPVS connection. Move it into handle_response_icmp. Also, force rerouting if sending to local client because IPv4 stack uses addresses from the route. Signed-off-by: Julian Anastasov <ja@ssi.bg> Signed-off-by: Simon Horman <horms@verge.net.au>
2010-10-21ipvs: create ip_vs_defrag_userJulian Anastasov

2010-10-21ipvs: fix CHECKSUM_PARTIAL for TUN methodJulian Anastasov
The recent change in IP_VS_XMIT_TUNNEL to set CHECKSUM_NONE is not correct. After adding IPIP header skb->csum becomes invalid but the CHECKSUM_PARTIAL case must be supported. So, use skb_forward_csum() which is most suitable for us to allow local clients to send IPIP to remote real server.

2010-10-21ipvs: do not schedule conns from real serversJulian Anastasov
This patch is needed to avoid scheduling of packets from local real server when we add ip_vs_in in LOCAL_OUT hook to support local client. Currently, when ip_vs_in can not find existing connection it tries to create new one by calling ip_vs_schedule. The default indication from ip_vs_schedule was if connection was scheduled to real server. If real server is not available we try to use the bypass forwarding method or to send ICMP error. But in some cases we do not want to use the bypass feature. So, add flag 'ignored' to indicate if the scheduler ignores this packet. Make sure we do not create new connections from replies. We can hit this problem for persistent services and local real server when ip_vs_in is added to LOCAL_OUT hook to handle local clients. Also, make sure ip_vs_schedule ignores SYN packets for Active FTP DATA from local real server. The FTP DATA connection should be created on SYN+ACK from client to assign correct connection daddr.

2010-10-21ipvs: switch to notrack modeJulian Anastasov
Change skb->ipvs_property semantic. This is preparation to support ip_vs_out processing in LOCAL_OUT. ipvs_property=1 will be used to avoid expensive lookups for traffic sent by transmitters. Now when conntrack support is not used we call ip_vs_notrack method to avoid problems in OUTPUT and POST_ROUTING hooks instead of exiting POST_ROUTING as before.

2010-10-21ipvs: optimize checksums for appsJulian Anastasov
Avoid full checksum calculation for apps that can provide info whether csum was broken after payload mangling. For now only ip_vs_ftp mangles payload and it updates the csum, so the full recalculation is avoided for all packets. Add CHECKSUM_UNNECESSARY for snat_handler (TCP and UDP). It is needed to support SNAT from local address for the case when csum is fully recalculated. Signed-off-by: Julian Anastasov <ja@ssi.bg> Signed-off-by: Simon Horman <horms@verge.net.au>
2010-10-21ipvs: fix CHECKSUM_PARTIAL for TCP, UDPJulian Anastasov
Fix CHECKSUM_PARTIAL handling. Tested for IPv4 TCP, UDP not tested because it needs network card with HW CSUM support. May be fixes problem where IPVS can not be used in virtual boxes. Problem appears with DNAT to local address when the local stack sends reply in CHECKSUM_PARTIAL mode. Fix tcp_dnat_handler and udp_dnat_handler to provide vaddr and daddr in right order (old and new IP) when calling tcp_partial_csum_update/udp_partial_csum_update (CHECKSUM_PARTIAL).
