2013-04-18netfilter: add my copyright statementsPatrick McHardy1-1/+1
Add copyright statements to all netfilter files which have had significant changes done by myself in the past. Some notes: - nf_conntrack_ecache.c was incorrectly attributed to Rusty and Netfilter Core Team when it got split out of nf_conntrack_core.c. The copyrights even state a date which lies six years before it was written. It was written in 2005 by Harald and myself. - net/ipv{4,6}/netfilter.c, net/netfitler/nf_queue.c were missing copyright statements. I've added the copyright statement from net/netfilter/core.c, where this code originated - for nf_conntrack_proto_tcp.c I've also added Jozsef, since I didn't want it to give the wrong impression Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2013-02-19netfilter: nf_ct_helper: better logging for dropped packetsPablo Neira Ayuso1-2/+6
Connection tracking helpers have to drop packets under exceptional situations. Currently, the user gets the following logging message in case that happens: nf_ct_%s: dropping packet ... However, depending on the helper, there are different reasons why a packet can be dropped. This patch modifies the existing code to provide more specific error message in the scope of each helper to help users to debug the reason why the packet has been dropped, ie: nf_ct_%s: dropping packet: reason ... Thanks to Joe Perches for many formatting suggestions. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2012-06-16netfilter: nf_ct_helper: allocate 16 bytes for the helper and policy namesPablo Neira Ayuso1-6/+2
This patch modifies the struct nf_conntrack_helper to allocate the room for the helper name. The maximum length is 16 bytes (this was already introduced in 2.6.24). For the maximum length for expectation policy names, I have also selected 16 bytes. This patch is required by the follow-up patch to support user-space connection tracking helpers.

2008-11-17netfilter: nf_conntrack: connection tracking helper name persistent aliasesPablo Neira Ayuso1-0/+1
This patch adds the macro MODULE_ALIAS_NFCT_HELPER that defines a way to provide generic and persistent aliases for the connection tracking helpers. This next patch requires this patch. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org> Signed-off-by: Patrick McHardy <kaber@trash.net>
2008-04-14[NETFILTER]: nf_conntrack: replace NF_CT_DUMP_TUPLE macro indrection by function callJan Engelhardt1-3/+3
Directly call IPv4 and IPv6 variants where the address family is easily known. Signed-off-by: Jan Engelhardt <jengelh@computergmbh.de> Signed-off-by: Patrick McHardy <kaber@trash.net>
2008-04-14[NETFILTER]: nf_conntrack: add tuplehash l3num/protonum accessorsPatrick McHardy1-2/+2
Add accessors for l3num and protonum and get rid of some overly long expressions. Signed-off-by: Patrick McHardy <kaber@trash.net>
2008-03-25[NETFILTER]: nf_conntrack: introduce expectation classes and policiesPatrick McHardy1-3/+8
Introduce expectation classes and policies. An expectation class is used to distinguish different types of expectations by the same helper (for example audio/video/t.120). The expectation policy is used to hold the maximum number of expectations and the initial timeout for each class. The individual classes are isolated from each other, which means that for example an audio expectation will only evict other audio expectations.

2007-07-10[NETFILTER]: nf_conntrack: reduce masks to a subset of tuplesPatrick McHardy1-3/+0
Since conntrack currently allows to use masks for every bit of both helper and expectation tuples, we can't hash them and have to keep them on two global lists that are searched for every new connection. This patch removes the never used ability to use masks for the destination part of the expectation tuple and completely removes masks from helpers since the only reasonable choice is a full match on l3num, protonum and src.u.all.
