Currently there is a wild mix of nf_conntrack_expect_, nf_ct_exp_, expect_, exp_, ... Consistently use nf_ct_ as prefix for exported functions. Signed-off-by:

Convert conntrack hash to hlists to reduce its size and cache footprint. Since the default hashsize to max. entries ratio sucks (1:16), this patch doesn't reduce the amount of memory used for the hash by default, but instead uses a better ratio of 1:8, which results in the same max. entries value. One thing worth noting is early_drop. It really should use LRU, so it now has to iterate over the entire chain to find the last unconfirmed entry. Since chains shouldn't be very long and the entire operation is very rare this shouldn't be a problem. Signed-off-by:

This kills the global 'destroy' operation which was used by NAT. Instead it uses the extension infrastructure so that multiple extensions can register own operations. Signed-off-by:

I will split 'struct nf_nat_info' out from conntrack. So I cannot use 'offsetof' to get the pointer to conntrack from it. Signed-off-by:

Old space allocator of conntrack had problems about extensibility. - It required slab cache per combination of extensions. - It expected what extensions would be assigned, but it was impossible to expect that completely, then we allocated bigger memory object than really required. - It needed to search helper twice due to lock issue. Now basic informations of a connection are stored in 'struct nf_conn'. And a storage for extension (helper, NAT) is allocated by kmalloc. Signed-off-by:

Along comes... xt_u32, a revamped ipt_u32 from POM-NG, Plus: * 2007-06-02: added ipv6 support * 2007-06-05: uses kmalloc for the big buffer * 2007-06-05: added inversion * 2007-06-20: use skb_copy_bits() and get rid of the big buffer and lock (suggested by Pablo Neira Ayuso) Signed-off-by:Jan Engelhardt <jengelh@gmx.de> Signed-off-by:

This explains the allowed upper protocol numbers. IP6T_F_NOPROTO was introduced to use 0 as Hop-by-Hop option header, not wildcard. But that seemed to be forgotten. 0 has been used as wildcard since 2002-08-23. Signed-off-by:

This cleanup fell out after adding L2TP support where a new encap_rcv funcptr was added to struct udp_sock. Have XFRM use the new encap_rcv funcptr, which allows us to move the XFRM encap code from udp.c into xfrm4_input.c. Make xfrm4_rcv_encap() static since it is no longer called externally.

This patch extracts common code from irttp_open_tsap() and irttp_dup() into a new function to 1) avoid code duplication, 2) help avoid forgetting object initialization in the tsap duplication path in the future. Signed-off-by:

Introduce a new syscall TUNSETGROUP for group ownership setting of tap devices. The user now is allowed to send packages if either his euid or his egid matches the one specified via tunctl (via -u or -g respecitvely). If both, gid and uid, are set via tunctl, both have to match. Signed-off-by:

Remove stats_lock pointers from qdisc-internal structures, in all cases it points to dev->queue_lock. The only case where it is necessary is for top-level qdiscs, where it might also point to dev->ingress_lock in case of the ingress qdisc. Also remove it from actions completely, it always points to the actions internal lock. Signed-off-by:

The generic estimator is always built in anways and all the config options does is prevent including a minimal amount of code for setting it up. Additionally the option is already automatically selected for most cases. Signed-off-by:
