      netfilter: ipt_CLUSTERIP: fix buffer overflow · 961ed183
      Vasiliy Kulikov authored 
      'buffer' string is copied from userspace.  It is not checked whether it is
zero terminated.  This may lead to overflow inside of simple_strtoul().
Changli Gao suggested to copy not more than user supplied 'size' bytes.

It was introduced before the git epoch.  Files "ipt_CLUSTERIP/*" are
root writable only by default, however, on some setups permissions might be
relaxed to e.g. network admin user.

      netfilter: xtables: fix reentrancy · db856674
      Eric Dumazet authored 
      commit f3c5c1bf (make ip_tables reentrant) introduced a race in
handling the stackptr restore, at the end of ipt_do_table()

We should do it before the call to xt_info_rdunlock_bh(), or we allow
cpu preemption and another cpu overwrites stackptr of original one.

A second fix is to change the underflow test to check the origptr value
instead of 0 to detect underflow, or else we allow a jump from different
hooks.

      netfilter: ipset: fix checking the type revision at create command · 5c1aba46
      Jozsef Kadlecsik authored 
      The revision of the set type was not checked at the create command: if the
userspace sent a valid set type but with not supported revision number,
it'd create a loop.

      netfilter: ipset: fix address ranges at hash:*port* types · 5e0c1eb7
      Jozsef Kadlecsik authored 
      The hash:*port* types with IPv4 silently ignored when address ranges
with non TCP/UDP were added/deleted from the set and used the first
address from the range only.

      niu: Rename NIU parent platform device name to fix conflict. · a769f496
      David S. Miller authored 
      When the OF device driver bits were converted over to the platform
device infrastructure in commit 74888760
("dt/net: Eliminate users of of_platform_{,un}register_driver") we
inadvertantly created probing problems in the OF case.

The NIU driver creates a dummy platform device to represent the
board that contains one or more child NIU devices.  Unfortunately
we use the same name, "niu", as the OF device driver itself uses.

The result is that we try to probe the dummy "niu" parent device we
create, and since it has a NULL ofdevice pointer etc. everything
explodes:
