2007-10-10[NETFILTER]: nf_conntrack_netlink: add support to related connectionsPablo Neira Ayuso1-0/+1
This patch adds support to relate a connection to an existing master connection. This patch is used by conntrackd to correctly replicate related connections.

2007-04-25[NETFILTER]: ctnetlink: add support for internal tcp connection tracking flags handlingPablo Neira Ayuso1-0/+4
This patch let userspace programs set the IP_CT_TCP_BE_LIBERAL flag to force the pickup of established connections. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org> Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
2006-06-17[NETFILTER]: ctnetlink: fix NAT configurationPatrick McHardy1-1/+3
The current configuration only allows to configure one manip and overloads conntrack status flags with netlink semantic. Signed-off-by: Patrick Mchardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
2006-01-05[NETFILTER]: ctnetlink: Fix dumping of helper namePatrick McHardy1-2/+0
Properly dump the helper name instead of internal kernel data. Based on patch by Marcus Sundberg <marcus@ingate.com>. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>

2005-10-10[NETFILTER]: Use only 32bit counters for CONNTRACK_ACCTHarald Welte1-2/+4
Initially we used 64bit counters for conntrack-based accounting, since we had no event mechanism to tell userspace that our counters are about to overflow. With nfnetlink_conntrack, we now have such a event mechanism and thus can save 16bytes per connection. Signed-off-by: Harald Welte <laforge@netfilter.org> Signed-off-by: David S.

2005-10-10[NETFILTER] ctnetlink: add one nesting level for TCP statePablo Neira Ayuso1-1/+8
To keep consistency, the TCP private protocol information is nested attributes under CTA_PROTOINFO_TCP. This way the sequence of attributes to access the TCP state information looks like here below: CTA_PROTOINFO CTA_PROTOINFO_TCP CTA_PROTOINFO_TCP_STATE instead of: CTA_PROTOINFO CTA_PROTOINFO_TCP_STATE Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org> Signed-off-by: Harald Welte <laforge@netfilter.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2005-08-29[NETFILTER]: don't use nested attributes for conntrack_expectHarald Welte1-1/+2
We used to use nested nfattr structures for ip_conntrack_expect. This is bogus, since ip_conntrack and ip_conntrack_expect are communicated in different netlink message types. both should be encoded at the top level attributes, no extra nesting required. This patch addresses the issue. Signed-off-by: Harald Welte <laforge@netfilter.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2005-08-29[NETFILTER]: Add ctnetlink subsystemHarald Welte1-0/+123
Add ctnetlink subsystem for userspace-access to ip_conntrack table. This allows reading and updating of existing entries, as well as creating new ones (and new expect's) via nfnetlink. Please note the 'strange' byte order: nfattr (tag+length) are in host byte order, while the payload is always guaranteed to be in network byte order. This allows a simple userspace process to encapsulate netlink messages into arch-independent udp packets by just processing/swapping the headers and not knowing anything about the actual payload.
