      [IPV6]: Don't hold extra ref count in ipv6_ifa_notify · 4641e7a3
      由 Herbert Xu 提交于 
      Currently the logic in ipv6_ifa_notify is to hold an extra reference
count for addrconf dst's that get added to the routing table.  Thus,
when addrconf dst entries are taken out of the routing table, we need
to drop that dst.  However, addrconf dst entries may be removed from
the routing table by means other than __ipv6_ifa_notify.

So we're faced with the choice of either fixing up all places where
addrconf dst entries are removed, or dropping the extra reference count
altogether.

I chose the latter because the ifp itself always holds a dst reference
count of 1 while it's alive.  This is dropped just before we kfree the
ifp object.  Therefore we know that in __ipv6_ifa_notify we will always
hold that count.

This bug was found by Eric W. Biederman.

      [NET]: Use NIP6_FMT in kernel.h · 46b86a2d
      由 Joe Perches 提交于 
      There are errors and inconsistency in the display of NIP6 strings.
	ie: net/ipv6/ip6_flowlabel.c

There are errors and inconsistency in the display of NIPQUAD strings too.
	ie: net/netfilter/nf_conntrack_ftp.c

This patch:
	adds NIP6_FMT to kernel.h
	changes all code to use NIP6_FMT
	fixes net/ipv6/ip6_flowlabel.c
	adds NIPQUAD_FMT to kernel.h
	fixes net/netfilter/nf_conntrack_ftp.c
	changes a few uses of "%u.%u.%u.%u" to NIPQUAD_FMT for symmetry to NIP6_FMT

      [IPV6]: Fix address deletion · 1d142804
      由 Kristian Slavov 提交于 
      If you add more than one IPv6 address belonging to the same prefix and 
delete the address that was last added, routing table entry for that 
prefix is also deleted.
Tested on 2.6.14.4

To reproduce:
ip addr add 3ffe::1/64 dev eth0
ip addr add 3ffe::2/64 dev eth0
/* wait DAD */
sleep 1
ip addr del 3ffe::2/64 dev eth0
ip -6 route

(route to 3ffe::/64 should be gone)

In ipv6_del_addr(), if ifa == ifp, we set ifa->if_next to NULL, and later 
assign ifap = &ifa->if_next, effectively terminating the for-loop.
This prevents us from checking if there are other addresses using the same 
prefix that are valid, and thus resulting in deletion of the prefix.
This applies only if the first entry in idev->addr_list is the address to 
be deleted.

      [IPV6]: Fix route lifetime. · 3dd4bc68
      由 YOSHIFUJI Hideaki 提交于 
      The route expiration time is stored in rt6i_expires in jiffies.
The argument of rt6_route_add() for adding a route is not the
expiration time in jiffies nor in clock_t, but the lifetime
(or time left before expiration) in clock_t.

Because of the confusion, we sometimes saw several strange errors
(FAILs) in TAHI IPv6 Ready Logo Phase-2 Self Test.
The symptoms were analyzed by Mitsuru Chinen <CHINEN@jp.ibm.com>.

      [IPV4]: Replace __in_dev_get with __in_dev_get_rcu/rtnl · e5ed6399
      由 Herbert Xu 提交于 
      The following patch renames __in_dev_get() to __in_dev_get_rtnl() and
introduces __in_dev_get_rcu() to cover the second case.

1) RCU with refcnt should use in_dev_get().
2) RCU without refcnt should use __in_dev_get_rcu().
3) All others must hold RTNL and use __in_dev_get_rtnl().

There is one exception in net/ipv4/route.c which is in fact a pre-existing
race condition.  I've marked it as such so that we remember to fix it.

This patch is based on suggestions and prior work by Suzanne Wood and
Paul McKenney.

      [CRYPTO]: crypto_free_tfm() callers no longer need to check for NULL · 573dbd95
      由 Jesper Juhl 提交于 
      Since the patch to add a NULL short-circuit to crypto_free_tfm() went in,
there's no longer any need for callers of that function to check for NULL.
This patch removes the redundant NULL checks and also a few similar checks
for NULL before calls to kfree() that I ran into while doing the
crypto_free_tfm bits.

I've succesfuly compile tested this patch, and a kernel with the patch 
applied boots and runs just fine.

When I posted the patch to LKML (and other lists/people on Cc) it drew the
following comments :

 J. Bruce Fields commented
  "I've no problem with the auth_gss or nfsv4 bits.--b."

 Sridhar Samudrala said
  "sctp change looks fine."

 Herbert Xu signed off on the patch.

So, I guess this is ready to be dropped into -mm and eventually mainline.
