      netfilter: nf_tables: fix missing rules flushing per table · cf9dc09d
      Pablo Neira Ayuso authored
      This patch allows you to atomically remove all rules stored in
      a table via the NFT_MSG_DELRULE command. You only need to indicate
      the specific table and no chain to flush all rules stored in that
      table.

      netfilter: xt_hashlimit: fix proc entry leak in netns destroy path · b4ef4ce0
      Sergey Popovich authored
      In (32263dd1 netfilter: xt_hashlimit: fix namespace destroy path)
      the hashlimit_net_exit() function is always called right before
      hashlimit_mt_destroy() to release netns data. If you use xt_hashlimit
      with IPv4 and IPv6 together, this produces the following splat via
      netconsole in the netns destroy path:

       WARNING: at /usr/src/linux-3.2.52/debian/build/source_netctl/fs/proc/generic.c:849
       remove_proc_entry+0x217/0x22e()
       Hardware name:
       remove_proc_entry: removing non-empty directory 'net/ip6t_hashlimit', leaking at least 'IN-REJECT'
      
      This is due to lack of removal net/ip6t_hashlimit/* entries in
      hashlimit_proc_net_exit(), since only IPv4 entries are deleted. Fix
      it by always removing the IPv4 and IPv6 entries and their parent
      directories in the netns destroy path.
