Calling an incoming NET/ROM-encapsulated IP packet an error if the

For reason that probably nobody recalls NET/ROM does it's actual
packet transmission in nr_rebuild_header and even treats invocation of
it's hard_start_xmit method nr_xmit as a bug.  Fix that by splitting
the job done by nr_rebuild_header into two halves.  Along with that we
now also can get rid of the silly clone of the skb on transmit.

We can get this value in an TIMESTAMP_ECHO and/or in an ELAPSED_TIME option, if
receiving both give precendence to the biggest one.

In my tests they are very close if not equal at all times, so we may well think
about removing the code in CCID3 that inserts this option and leaving this to
the core, and perhaps even use just TIMESTAMP_ECHO including the elapsed time.

We should not restrict use of ieee80211 to only when wireless drivers
are enabled.  In-development and out-of-tree drivers may wish to use it,
and by removing this restriction we eliminate a circular dependency.

Asc2ax was still using a static buffer for all invocations which isn't
exactly SMP-safe.  Change asc2ax to take an additional result buffer as
the argument.  Change all callers to provide such a buffer.

This one only really is a fix for ROSE and as per recent discussions
there's still much more to fix in ROSE ...

	One such place that can damage the dst refcnts is route.c with
CONFIG_IP_ROUTE_MULTIPATH_CACHED enabled, i don't see the user's
.config. In this new code i see that rt_intern_hash is called before
dst->refcnt is set to 1, dst is the 2nd arg to rt_intern_hash.

Arg 2 of rt_intern_hash must come with refcnt 1 as it is added to
table or dropped depending on error/add/update. One such example is
ip_mkroute_input where __mkroute_input return rth with refcnt 0 which
is provided to rt_intern_hash. ip_mkroute_output looks like a 2nd such
place. Appending untested patch for comments and review.  The idea is
to put previous reference as we are going to return next result/error.

A UDP packet may contain extra data that needs to be trimmed off.
But when doing so, UDP forgets to fixup the skb checksum if CHECKSUM_HW
is being used.

I think this explains the case of a NFS receive using skge driver
causing 'udp hw checksum failures' when interacting with a crufty
settop box.

When we copy 32bit ->msg_control contents to kernel, we walk the same
userland data twice without sanity checks on the second pass.

Second version of this patch: the original broke with 64-bit arches
running 32-bit-compat-mode executables doing sendmsg() syscalls with
unaligned CMSG data areas

Another thing is that we use kmalloc() to allocate and sock_kfree_s()
to free afterwards; less serious, but also needs fixing.

The sunrpc stats are collected in unsigned integers, but they are printed
with '%d'.  That can result in negative numbers in /proc/net/rpc when the
highest bit of a counter is set.  The following patch changes '%d' to '%u'
where appropriate.

When registering an RPC cache, cache_register() always sets the owner as the
sunrpc module.  However, there are RPC caches owned by other modules.  With
the incorrect owner setting, the real owning module can be removed potentially
with an open reference to the cache from userspace.

For example, if one were to stop the nfs server and unmount the nfsd
filesystem, the nfsd module could be removed eventhough rpc.idmapd had
references to the idtoname and nametoid caches (i.e.
/proc/net/rpc/nfs4.<cachename>/channel is still open).  This resulted in a
system panic on one of our machines when attempting to restart the nfs
services after reloading the nfsd module.

The following patch adds a 'struct module *owner' field in struct
cache_detail.  The owner is further assigned to the struct proc_dir_entry
in cache_register() so that the module cannot be unloaded while user-space
daemons have an open reference on the associated file under /proc.
