* nf: nfnl_*_str2copy_mode() should return intThomas Graf2014-08-262-2/+2
| | | | | | | | | | | | | ... to be able to return a negative error code for unknown modes. [thaller@redhat.com: This is potentially an ABI break, but since the size of the enum is implementation defined, it seems anyway unstable to have them as function arguments/return values.] http://lists.infradead.org/pipermail/libnl/2014-August/001616.html Signed-off-by: Thomas Graf <tgraf@suug.ch> Signed-off-by: Thomas Haller <thaller@redhat.com>

* lib/socket: retry generate local port in nl_connect on ADDRINUSEThomas Haller2014-05-061-0/+9
| | | | | | | | | | | | | | | | | | | | | It can easily happen that the generated local netlink port is alrady in use. In that case bind will fail with ADDRINUSE. Users of libnl3 could workaround this, by managing the local ports themselves, but sometimes these users are libraries too and they also don't know which ports might be used by other components. This patch changes that nl_socket_alloc() no longer initilizes the local port id immediately. Instead it will be initialized when the user calls nl_socket_get_local_port() the first time and thereby shows interest in the value. If bind() fails with ADDRINUSE, check if the user ever cared about the local port, i.e. whether the local port is still unset. If it is still unset, assume that libnl should choose a suitable port and retry until an unused port can be found. Signed-off-by: Thomas Haller <thaller@redhat.com>

* route: update kernel header snmp.h and fix inet6_parse_protinfo() after ↵Thomas Haller2014-03-211-0/+6
| | | | | | | | | | | | | | | | | | | | kernel API breakage Take 'include/uapi/linux/snmp.h' from current kernel v3.13 (commit d8ec26d7f8287f5788a494f56e8814210f0e64be). The header file added new values for IPSTATS_MIB_* and ICMP6_MIB_*, but more importantly, the kernel broke user space API by reordering enum values in IPSTATS_MIB_*. Add a workaround when parsing IFLA_PROTINFO trying to be compatible with both older and newer kernels. Note that this workaround might fail for some specific kernel versions by assuming the old enum value mapping, although the kernel version already contains the API change. In this case rtnl_link_get_stat() mixes up values. Acked-by: Thomas Graf <tgraf@suug.ch> Signed-off-by: Thomas Haller <thaller@redhat.com>

* act: remove rtnl_act_alloc_cache()Cong Wang2014-01-151-4/+0
| | | | | | | | | | | | | | | | It is complicated to cache tc actions, they are different from tc qdisc's and filters by design. So, it is simple if we just don't cache them. This patch only removes the tc action cache allocation API. We still need to bypass the libnl cache layer from scratch, but that would not break ABI any more, therefore we can do it later.
