fib_info can be shared by many route prefixes but we don't want
duplicate alternative routes for a prefix+tos+priority. Last change
was not correct to check fib_treeref because it accounts usage from
other prefixes. Additionally, avoid replacement without error if new
route is same, as Joonwoo Park suggests.

Fixes: http://bugzilla.kernel.org/show_bug.cgi?id=9825
The inet_diag_lock_handler function uses ERR_PTR to encode errors but
its callers were testing against NULL.
This only happens when the only inet_diag modular user, DCCP, is not
built into the kernel or available as a module.
Also there was a problem with not dropping the mutex lock when a handler
was not found, also fixed in this patch.
This caused an OOPS and ss would then hang on subsequent calls, as
&inet_diag_table_mutex was being left locked.
Thanks to spike at ml.yaroslavl.ru for report it after trying 'ss -d'
on a kernel that doesn't have DCCP available.
This bug was introduced in cset
d523a328fb ("Fix inet_diag dead-lock
regression"), after 2.6.24-rc3, so just 2.6.24 seems to be affected.

When ip_fragment has to hit the slow path the value of skb->truesize

This patch adds support for combined mode algorithms with GCM being
the first algorithm supported.
Combined mode algorithms can be added through the xfrm_user interface
using the new algorithm payload type XFRMA_ALG_AEAD. Each algorithms
is identified by its name and the ICV length.
For the purposes of matching algorithms in xfrm_tmpl structures,
combined mode algorithms occupy the same name space as encryption
algorithms. This is in line with how they are negotiated using IKE.

We want IPV6HEADER matching for the non-advanced default netfilter
configuration, since it's part of the standard netfilter setup of at
least some distributions (eg Fedora).
Otherwise NETFILTER_ADVANCED loses much of its point, since even
non-advanced users would have to enable all the advanced options just to
get a working IPv6 netfilter setup.

returns an unsigned long number of bytes that couldn't be copied.

not, then gss_pipe_upcall() should punt any partial read, just like the
