2013-12-17build: fix build failure when using different build dir (make distcheck)Thomas Haller
`make distcheck` builds outside the source directory using `../configure --srcdir=..`. This was broken because libnl.sym was expected in the $(top_srcdir) instead of $(top_builddir). Signed-off-by: Thomas Haller <thaller@redhat.com>

2013-09-05nl_cb: store nl_cb_type in struct nl_cbArend van Spriel
The application could use the same handler for multiple nl_cb_type events. This patch stores the nl_cb_type in the nl_cb struct during the callback. This allows the application to obtain that information using the new nl_cb_active_type() function. This way the callback signature remains as is so existing applications are not affected.

2013-09-05netfilter/ct: support optional CTA_ZONE attributeHolger Eitzenberger
Newer kernels support conntrack zones, which help to partition the conntrack table into virtual conntrack tables. This patch is for adding support for the optional attribute, adds setters and getters, and adds support for the zone ID in the conntrack dumper. An example entry in NL_DUMP_LINE format looks like: tcp SYN_SENT 10.128.128.99:43354 <-> 10.128.129.20:22 zone 1 Signed-off-by: Holger Eitzenberger <holger@eitzenberger.org> Signed-off-by: Thomas Graf <tgraf@suug.ch>
2013-09-05netfilter/ct: support optional CTA_TIMESTAMP attributeHolger Eitzenberger
Recent kernels support conntrack time stamping, which is a helpful feature to determine the duration of a flow without building a flow cache in your user space application, just to keep the 'start' time of your flow. Timestamps are recorded with nanosecond resolution once this feature is enabled. This patch adds optional support for the CTA_TIMESTAMP, then modifies the dump routine to write that info in a format similar to /proc/net/nf_conntrack. This is an example output when using NL_DUMP_LINE: udp 10.128.128.28:56836 <-> 10.128.129.255:8612 delta-time 30 Signed-off-by: Holger Eitzenberger <holger@eitzenberger.org> Signed-off-by: Thomas Graf <tgraf@suug.ch>

2013-08-21fix double free caused by freeing link af_data in rtnl_link_set_family()Jiri Pirko
Introduced by commit 8026fe2e3a9089eff3f5a06ee6e3cc78d96334ed ("link: Free and realloc af specific data upon rtnl_link_set_family()") link->l_af_data[link->l_af_ops->ao_family] is freed here but not set to zero. That leads to double free made by link_free_data->do_foreach_af. Fix this by setting link->l_af_data[link->l_af_ops->ao_family] to zero rigth after free.

2013-07-19Add support for inet diag Netlink protocol.Joe Damato
- Inet diag allows users to gather low-level socket information. - This library provides a higher-level API for creating inetdiag requests (via idiagnl_connect and idiagnl_send_simple) and parsing the replies (via idiagnl_msg_parse). A cache is also provided (via idiagnl_msg_alloc_cache). - Request and message objects provide APIs for accessing and setting the various properties of each. - This library also allows the user to parse the inetdiag response attributes which contain information about traffic class, TOS, congestion, socket memory info, and more depending on the kernel version used. - Includes doxygen documentation.

2013-06-27msg: Avoid returning a negative value for nlmsg_attrlen()Thomas Graf
If a hdrlen was provided that was greather than the actual message length, a negative attributes length would result. This was typically happening for RTM_GETLINK requests where we can get a away with a 4 bytes header on the request side but the response would use a 16 bytes header. This resulted in strange -8 bytes leftover debug messages. Signed-off-by: Thomas Graf <tgraf@suug.ch>
