2010-07-15build: update libnetfilter_conntrack dependency (>= 0.0.102)Pablo Neira Ayuso
We require the latest libnetfilter_conntrack version to fix several bugs. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2010-07-15conntrackd: warn on TCPWindowTracking option (it requires kernel >= 2.6.35)Pablo Neira Ayuso
This patch adds a comment on the TCPWindowTracking option to warn that this will be supported since the Linux kernel 2.6.35. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2010-07-13conntrackd: fix parsing of NAT sequence adjustment in synchronization messagesPablo Neira Ayuso
This patch fixes a bug that results in an incorrect parsing of the NAT sequence adjustment in synchronization messages. Spotted by Adam Gundy in the following message that was sent to the netfilter ML: http://marc.info/?l=netfilter&m=127894708222913&w=2 Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

2010-07-09conntrackd: replace cyptic 'mfrm' with 'malformed' in '-s'Mohit Mehta
2010-07-09conntrackd: replace cryptic `mfrm' by `malformed' in `-s'Mohit Mehta
Looking at the output of `conntrackd -s`; I didn't know what 'mfrm' meant under the 'message sequence tracking' section so I had to look up the code for this. While doing so, I replaced 'mfrm' with 'malformed' in the output since I thought other users might be confused as well as I was looking at that word.

2010-07-07conntrackd: setup event reliability after handler creationPablo Neira Ayuso
This patch enables the event reliability in an early stage of the event handler initialization. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2010-07-07conntrackd: open event handler once cache has been populatedPablo Neira Ayuso
With this patch, we open the event handler once the internal cache (if any) is populated. This reduces the chances of a possible premature overrun if we lauch conntrackd in a busy firewall. However, we may still start with an internal cache that may differ a bit from the once in the kernel. This patch has no impact in setups where conntrackd is started in a spare firewall.

2010-07-07conntrackd: enforce strict logic for NetlinkBufferSize[*] clausesMohit Mehta
- NetlinkBufferSize value passed to the kernel gets doubled [see SO_RCVBUF in net/core/sock.c]; it's halved now before it gets sent to the kernel. This ensures that daemon starts up with a netlink socket buffer size equal to the value set for NetlinkBufferSize in configuration file. - Previously, netlink socket buffer size would only stop increasing after it had increased beyond NetlinkBufferSizeMaxGrowth value. With this commit netlink socket buffer size increases as long as it is less than or equal to NetlinkBufferSizeMaxGrowth value.

2010-07-05conntrack: add zone supportPablo Neira Ayuso
This patch adds `--zone' to the command line tool. This adds the missing user-space support for Patrick's McHardy iptables CT target. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

2010-07-01conntrackd: fix ICMPv6 supportPablo Neira Ayuso
This patch fixes several minor nitpicks to support IPv6 failover: * ICMPv6 type/code/id were missing in synchronization messages. * The use of '-' as string in the configuration file was not allowed. * Include example in configuration file under doc/.

2010-07-01conntrack: cleanup parsing of the NAT argumentsPablo Neira Ayuso
This patch cleans up nat_parse() and it also displays nicer error message for malformed arguments. % conntrack -L --src-nat :80 conntrack v0.9.14 (conntrack-tools): No IP specified Try `conntrack -h' or 'conntrack --help' for more information. % conntrack -L --src-nat 1.1.1.1: conntrack v0.9.14 (conntrack-tools): No port specified after `:' Try `conntrack -h' or 'conntrack --help' for more information.

2010-07-01conntrack: fix `conntrack --[src|dst|any]-nat IP:PORT' if port mismatchesPablo Neira Ayuso
This patch fixes the filtering if the IP matches an entry but the PORT does not matches. Without this patch, the entry is shown when it should be not. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2010-07-01conntrack: --[src|dst|any]-nat requires IP:PORT as argumentPablo Neira Ayuso
This patch restricts the behaviour that we previously introduced in 142606c60808b3ab0496155ac3d086765e6baef3. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2010-07-01conntrack: fix `conntrack --any-nat 1.1.1.1' filteringPablo Neira Ayuso

2010-07-01conntrack: fix `conntrack --src-nat 1.1.1.1' if PAT appliedPablo Neira Ayuso
This patch fixes another scenario in which the flow has some PAT mangling and we passed the src-nat address that we want to use to perform the filtering. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

2010-07-01conntrack: fix bogus NATted flows in filteringPablo Neira Ayuso
With this patch, conntrack does not show bogus entries that have no NAT applied due to a relaxed checking. conntrack -L --src-nat :80 tcp 6 342824 ESTABLISHED src=XX.214.188.80 dst=66.XX.7.180 sport=80 dport=13749 packets=4 bytes=6000 [UNREPLIED] src=66.XX.7.180 dst=XX.214.188.80 sport=13749 dport=80 packets=0 bytes=0 mark=0 secmark=0 use=1 conntrack v0.9.14 (conntrack-tools): 1 flow entries have been shown.

In 142606c60808b3ab0496155ac3d086765e6baef3, I re-introduced the inconsistent behaviour that I described in 85f94171a71880c744f265268f33ad58819caa74. Great. This patch fixes this again. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

2010-06-17conntrackd: complete TCP window scale supportPablo Neira Ayuso
In commit 56817d1c0cc30bcd65c56c2f73634b256603cc4d, I added the TCP window scale factor support but it was incomplete. We have to set the IP_CT_TCP_FLAG_WINDOW_SCALE flag to update the td_scale field via ctnetlink. Check nlattr_to_tcp(...) function in nf_conntrack_proto_tcp.c for more details.

2010-06-17conntrack: `-L --src-nat --dst-nat' filter using AND, not OR logicPablo Neira Ayuso
The patch that I committed in 2e06d62d341fdf936dbc1fa944d5e03f761aaf0e was incomplete. With it, `-L --src-nat --dst-nat' shows source-natted OR destination-natted flows. This patch changes the behaviour to show source-natted AND destination-natted flows. This is the consistent behaviour that we expect from conntrack (this is how it works for other options indeed).
