* [NETFILTER] nf_conntrack: clean up to reduce size of 'struct nf_conn'Harald Welte2006-03-201-17/+22
| | | | | | | | | | | | | | | | | | | | This patch moves all helper related data fields of 'struct nf_conn' into a separate structure 'struct nf_conn_help'. This new structure is only present in conntrack entries for which we actually have a helper loaded. Also, this patch cleans up the nf_conntrack 'features' mechanism to resemble what the original idea was: Just glue the feature-specific data structures at the end of 'struct nf_conn', and explicitly re-calculate the pointer to it when needed rather than keeping pointers around. Saves 20 bytes per conntrack on my x86_64 box. A non-helped conntrack is 276 bytes. We still need to save another 20 bytes in order to fit into to target of 256bytes.

* [NETFILTER] ip_queue: Fix wrong skb->len == nlmsg_len assumptionThomas Graf2006-03-071-1/+1
| | | | | | | | | | | | | The size of the skb carrying the netlink message is not equivalent to the length of the actual netlink message due to padding. ip_queue matches the length of the payload against the original packet size to determine if packet mangling is desired, due to the above wrong assumption arbitary packets may not be mangled depening on their original size.

* [NETFILTER]: Restore {ipt,ip6t,ebt}_LOG compatibilityPatrick McHardy2006-02-271-1/+6
| | | | | | | | | | | | | The nfnetlink_log infrastructure changes broke compatiblity of the LOG targets. They currently use whatever log backend was registered first, which means that if ipt_ULOG was loaded first, no messages will be printed to the ring buffer anymore. Restore compatiblity by using the old log functions by default and only use the nf_log backend if the user explicitly said so. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.
