* src: BAD_SIZEOFJiri Popelka2011-06-131-2/+2
| | | | | | | | | | | static analysis (analysis based only on compiling of sources, not based on running of binary) of the code revealed the following problem: libnfnetlink.c:481: Taking the size of pointer parameter "nlh" is suspicious. libnfnetlink.c:486: Taking the size of pointer parameter "nlh" is suspicious.

* nfnl: add nfnl_addattr8() functionPablo Neira Ayuso2009-06-111-0/+17
| | | | | | | This patch adds the function nfnl_addattr8() as it has been requested by Jozsef Kadlecsik, he needs it for his Netlink-port of ipset. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* nfnl: add nfnl_portid() to get the Netlink portID of a socketPablo Neira Ayuso2009-05-211-0/+10
| | | | | | | This patch adds the new interface nfnl_portid() to retrieve the Netlink portID that has been assigned to a given socket. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* rtnl: fix wrong netlink group bindings in the interface APIPablo Neira Ayuso2009-04-291-2/+1
| | | | | | | | | This patch removes RTMGRP_IPV4_ROUTE and RTMGRP_IPV4_IFADDR which report event notifications about changes in the route and address of interfaces. We are only interested in the interface link status so RTMGRP_LINK is enough. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* nfnl: allow disabling and enabling sequence trackingPablo Neira Ayuso2009-02-171-4/+33
| | | | | | | | | | | | This patch adds a couple of functions to enable and disable netlink sequence tracking. Since nfqueue goes over a unicast socket, the same channel to receive control messages and packets is used. This leads to race conditions that may trigger sporious out-of-sequence errors while creating queues and receiving high load of packets at the same time.

* Suppress iftable_up function which is not used.Eric Leblond2008-12-231-17/+0
| | | | | | Following compilation warning pointed out by Jan Engelhardt, this patch suppresses the iftable_up function which is of no use in this part of libnfnetlink library whom goal is to do ifindex to name resolution.
* Aligns buffers to maximum alignment of architecturelibnfnetlink-0.0.39Fabian Hugelshofer2008-06-181-3/+4
| | | | | | | | Aligns buffer to maximum aligment of architecture to make the cast of char pointers to struct pointers more portable. Packet decoding is still broken on particular platforms. Signed-off-by: Fabian Hugelshofer <hugelshofer2006@gmx.ch>

* Introduce nfnl_set_rcv_buffer_size to set the receive buffer size used by /C=EU/ST=EU/CN=Pablo Neira Ayuso/emailAddress=pablo@netfilter.org2008-01-131-42/+16
| | | | | | | | | | | | | nfnl_catch. This revision changes the behaviour of nfnl_catch which does not perform a peek-and-resize if the buffer size used by nfnl_recv is too small. The only known client which may be affected by this change is libnetfilter_conntrack. However, this library uses nfnl_catch to get conntrack events which are always much smaller than 4096 bytes (default receive buffer size). This change boosts up performance in the receive path since we do only one recv instead of two.
