2010-10-28fib: Fix fib zone and its hash leak on namespace stopPavel Emelyanov1-0/+2
When we stop a namespace we flush the table and free one, but the added fn_zone-s (and their hashes if grown) are leaked. Need to free. Tries releases all its stuff in the flushing code.

2010-10-289p: Add datasync to client side TFSYNC/RFSYNC for dotlVenkateswararao Jujjuri (JV)1-1/+1
SYNOPSIS size[4] Tfsync tag[2] fid[4] datasync[4] size[4] Rfsync tag[2] DESCRIPTION The Tfsync transaction transfers ("flushes") all modified in-core data of file identified by fid to the disk device (or other permanent storage device) where that file resides. If datasync flag is specified data will be fleshed but does not flush modified metadata unless that metadata is needed in order to allow a subsequent data retrieval to be correctly handled.

2010-10-21tproxy: fix hash locking issue when using port redirection in __inet_inherit_port()Balazs Scheidler1-1/+1
When __inet_inherit_port() is called on a tproxy connection the wrong locks are held for the inet_bind_bucket it is added to. __inet_inherit_port() made an implicit assumption that the listener's port number (and thus its bind bucket). Unfortunately, if you're using the TPROXY target to redirect skbs to a transparent proxy that assumption is not true anymore and things break. This patch adds code to __inet_inherit_port() so that it can handle this case by looking up or creating a new bind bucket for the child socket and updates callers of __inet_inherit_port() to gracefully handle __inet_inherit_port() failing. Reported by and original patch from Stephen Buck <stephen.buck@exinda.com>. See http://marc.info/?t=128169268200001&r=1&w=2 for the original discussion.

2010-10-21tproxy: kick out TIME_WAIT sockets in case a new connection comes in with the same tupleBalazs Scheidler1-1/+5
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.

As skb->protocol is not valid in LOCAL_OUT add parameter for address family in packet debugging functions.

2010-10-21ipvs: changes for local real serverJulian Anastasov1-0/+1
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: do not schedule conns from real serversJulian Anastasov1-1/+2
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 Anastasov1-1/+19
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 Anastasov1-2/+10

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>

2010-10-19ipvs: IPv6 tunnel modeHans Schillstrom1-0/+4
IPv6 encapsulation uses a bad source address for the tunnel. i.e. VIP will be used as local-addr and encap. dst addr. Decapsulation will not accept this. Example LVS (eth1 2003::2:0:1/96, VIP 2003::2:0:100) (eth0 2003::1:0:1/96) RS (ethX 2003::1:0:5/96) tcpdump 2003::2:0:100 > 2003::1:0:5: IP6 (hlim 63, next-header TCP (6) payload length: 40) 2003::3:0:10.50991 > 2003::2:0:100.http: Flags [S], cksum 0x7312 (correct), seq 3006460279, win 5760, options [mss 1440,sackOK,TS val 1904932 ecr 0,nop,wscale 3], length 0 In Linux IPv6 impl. you can't have a tunnel with an any cast address receiving packets (I have not tried to interpret RFC 2473) To have receive capabilities the tunnel must have: - Local address set as multicast addr or an unicast addr - Remote address set as an unicast addr. - Loop back addres or Link local address are not allowed. This causes us to setup a tunnel in the Real Server with the LVS as the remote address, here you can't use the VIP address since it's used inside the tunnel. Solution Use outgoing interface IPv6 address (match against the destination). i.e. use ip6_route_output() to look up the route cache and then use ipv6_dev_get_saddr(...) to set the source address of the encapsulated packet. Additionally, cache the results in new destination fields: dst_cookie and dst_saddr and properly check the returned dst from ip6_route_output. We now add xfrm_lookup call only for the tunneling method where the source address is a local one.

2010-10-17netns: reorder fields in struct netEric Dumazet2-11/+15
In a network bench, I noticed an unfortunate false sharing between 'loopback_dev' and 'count' fields in "struct net". 'count' is written each time a socket is created or destroyed, while loopback_dev might be often read in routing code. Move loopback_dev in a read mostly section of "struct net" Note: struct netns_xfrm is cache line aligned on SMP. (It contains a "struct dst_ops") Move it at the end to avoid holes, and reduce sizeof(struct net) by 128 bytes on ia32. Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.
