* conntrackd: add retention queue for TCP errorsPablo Neira Ayuso2009-09-231-2/+4
| | | | | | | | Under stress, the TCP stack may return EAGAIN if there is not space left in the sender buffer. We also enqueue any other error. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* conntrackd: fix MTU for TCP channelsPablo Neira Ayuso2009-09-111-0/+1
| | | | | | | | Use the TCP header size (20 bytes) instead of the UDP header size (8 bytes) to calculate the maximum packet size. Reported-by: Samuel Gauthier <samuel.gauthier@6wind.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* conntrackd: add support state-replication based on TCPPablo Neira Ayuso2009-08-231-1/+17
| | | | | | | | This patch adds support for TCP as protocol to replicate state-changes between two daemons. Note that this only makes sense with the notrack mode. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* sync-mode: fix broken dedicated-link change in multichannel layerPablo Neira Ayuso2009-03-201-0/+1
| | | | | | | This patch fixes a problem that was introduced while adding the multichannel support. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* sync-mode: add unicast UDP support to propagate state-changesPablo Neira Ayuso2009-03-131-0/+9
| | | | | | | | This patch adds support for unicast UDP to the channel infrastructure. With this patch, you can select UDP unicast to propagate state-changes instead of multicast. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* sync-mode: add abstract layer to make daemon independent of multicastPablo Neira Ayuso2009-03-121-0/+95
This patch reworks conntrackd to make it independent of the protocol used to propagate state-changes. This patch adds the channel layer abstraction, this layer allows you to add support for different protocols like unicast UDP or TIPC. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
