Public bug reported: Retrieving information about configured neighbors fail my application is running the following procedure:
neigh = NULL; cache = rtnl_neigh_alloc_cache(sk); while(NULL == neigh){ nl_cache_refill(sk, chache); neigh = rtnl_neigh_get(cache, ifindex, dst_addr); } with libnl3 3.2.21-1 this loop will never end, even when adding a static arp entry. However, with libnl-3.2.24 the neighbor lookup succeed. additional general info: $ lsb_release -rd Description: Ubuntu 14.04 LTS Release: 14.04 $ uname -r 3.13.0-24-generic $ apt-cache policy libnl-genl-3-200 libnl-route-3-200 libnl-genl-3-200: Installed: 3.2.21-1 Candidate: 3.2.21-1 Version table: *** 3.2.21-1 0 500 http://us.archive.ubuntu.com/ubuntu/ trusty/main amd64 Packages 100 /var/lib/dpkg/status libnl-route-3-200: Installed: 3.2.21-1 Candidate: 3.2.21-1 Version table: *** 3.2.21-1 0 500 http://us.archive.ubuntu.com/ubuntu/ trusty/main amd64 Packages 100 /var/lib/dpkg/status ** Affects: libnl3 (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1312419 Title: nl_cache_refill; rtnl_neigh_get fail to find neighbors in cache To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libnl3/+bug/1312419/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
