2008-04-14[NETFILTER]: nf_nat: kill helper and seq_adjust hooksPatrick McHardy
Connection tracking helpers (specifically FTP) need to be called before NAT sequence numbers adjustments are performed to be able to compare them against previously seen ones. We've introduced two new hooks around 2.6.11 to maintain this ordering when NAT modules were changed to get called from conntrack helpers directly. The cost of netfilter hooks is quite high and sequence number adjustments are only rarely needed however. Add a RCU-protected sequence number adjustment function pointer and call it from IPv4 conntrack after calling the helper. Signed-off-by: Patrick McHardy <kaber@trash.net>
2008-04-14[NETFILTER]: nf_conntrack_extend: warn on confirmed conntracksPatrick McHardy
New extensions may only be added to unconfirmed conntracks to avoid races when reallocating the storage. Also change NF_CT_ASSERT to use WARN_ON to get backtraces. Signed-off-by: Patrick McHardy <kaber@trash.net>
2008-04-14[NETFILTER]: nf_nat: don't add NAT extension for confirmed conntracksPatrick McHardy
Adding extensions to confirmed conntracks is not allowed to avoid races on reallocation. Don't setup NAT for confirmed conntracks in case NAT module is loaded late. The has one side-effect, the connections existing before the NAT module was loaded won't enter the bysource hash. The only case where this actually makes a difference is in case of SNAT to a multirange where the IP before NAT is also part of the range. Since old connections don't enter the bysource hash the first new connection from the IP will have a new address selected. This shouldn't matter at all.

2008-04-12NetLabel: Allow passing the LSM domain as a shared pointerPaul Moore
Smack doesn't have the need to create a private copy of the LSM "domain" when setting NetLabel security attributes like SELinux, however, the current NetLabel code requires a private copy of the LSM "domain". This patches fixes that by letting the LSM determine how it wants to pass the domain value. * NETLBL_SECATTR_DOMAIN_CPY The current behavior, NetLabel assumes that the domain value is a copy and frees it when done * NETLBL_SECATTR_DOMAIN New, Smack-friendly behavior, NetLabel assumes that the domain value is a reference to a string managed by the LSM and does not free it when done Signed-off-by: Paul Moore <paul.moore@hp.com> Acked-by: James Morris <jmorris@namei.org> Signed-off-by: David S.

2008-04-10[Syncookies]: Add support for TCP options via timestamps.Florian Westphal
Allow the use of SACK and window scaling when syncookies are used and the client supports tcp timestamps. Options are encoded into the timestamp sent in the syn-ack and restored from the timestamp echo when the ack is received. Based on earlier work by Glenn Griffin. This patch avoids increasing the size of structs by encoding TCP options into the least significant bits of the timestamp and by not using any 'timestamp offset'. The downside is that the timestamp sent in the packet after the synack will increase by several seconds. changes since v1: don't duplicate timestamp echo decoding function, put it into ipv4/syncookie.c and have ipv6/syncookies.c use it.
