This reverts commit 6c4711b4697d93424e4b1f76a9929ba844d714a5.
That patch breaks mesh config comparison between beacons/probe reponses, so
every beacon from a mesh network would be added as a new bss. Since the
comparison has to be performed for every received beacon I believe it is best to
save the mesh config in a format easy to compare, rather than do a bunch of
unaligned accesses to compare field by field.

We have been using __NET_IPV6_MAX for adjusting the size of array
for sysctl table, but it does not work any longer because of the
deprecation of NET_IPV6_xxx constants. Let's use DEVCONF_MAX
instead.

The RDMACTXT_F_LAST_CTXT bit was getting set incorrectly
when the last chunk in the read-list spanned multiple pages. This
resulted in a kernel panic when the wrong context was used to
build the RPC iovec page list.
RDMA_READ is used to fetch RPC data from the client for
NFS_WRITE requests. A scatter-gather is used to map the
advertised client side buffer to the server-side iovec and
associated page list.
WR contexts are used to convey which scatter-gather entries are
handled by each WR. When the write data is large, a single RPC may
require multiple RDMA_READ requests so the contexts for a single RPC
are chained together in a linked list. The last context in this list
is marked with a bit RDMACTXT_F_LAST_CTXT so that when this WR completes,
the CQ handler code can enqueue the RPC for processing.
The code in rdma_read_xdr was setting this bit on the last two
contexts on this list when the last read-list chunk spanned multiple
pages. This caused the svc_rdma_recvfrom logic to incorrectly build
the RPC and caused the kernel to crash because the second-to-last
context doesn't contain the iovec page list.
Modified the condition that sets this bit so that it correctly detects
the last context for the RPC.

The iWARP protocol limits RDMA read requests to a single scatter
entry. NFS/RDMA has code in rdma_read_max_sge() that is supposed to
limit the sge_count for RDMA read requests to 1, but the code to do
that is inside an #ifdef RDMA_TRANSPORT_IWARP block. In the mainline
kernel at least, RDMA_TRANSPORT_IWARP is an enum and not a
preprocessor #define, so the #ifdef'ed code is never compiled.
In my test of a kernel build with -j8 on an NFS/RDMA mount, this
problem eventually leads to trouble starting with:
svcrdma: Error posting send = -22
svcrdma : RDMA_READ error = -22
and things go downhill from there.
The trivial fix is to delete the #ifdef guard. The check seems to be
a remnant of when the NFS/RDMA code was not merged and needed to
compile against multiple kernel versions, although I don't think it
ever worked as intended. In any case now that the code is upstream
there's no need to test whether the RDMA_TRANSPORT_IWARP constant is
defined or not.
Without this patch, my kernel build on an NFS/RDMA mount using NetEffect
adapters quickly and 100% reproducibly failed with an error like:
ld: final link failed: Software caused connection abort
With the patch applied I was able to complete a kernel build on the
same setup.
(Tom Tucker says this is "actually an _ancient_ remnant when it had to
compile against iWARP vs. non-iWARP enabled OFA trees.")

From RFC341:
A temporary address is created only if this calculated Preferred
Lifetime is greater than REGEN_ADVANCE time units. In particular, an
implementation must not create a temporary address with a zero
Preferred Lifetime.

When receiving a prefix information from a routeur, only update the
lifetimes of the temporary address associated with that prefix.
Otherwise if one deprecated prefix is advertized, all your temporary
addresses will become deprecated.

Lockdep warning will be trigged while rfcomm connection closing.
The locks taken in rfcomm_dev_add:
rfcomm_dev_lock --> d->lock
In __rfcomm_dlc_close:
d->lock --> rfcomm_dev_lock (in rfcomm_dev_state_change)
There's two way to fix it, one is in rfcomm_dev_add we first locking
d->lock then the rfcomm_dev_lock
The other (in this patch), remove the locking of d->lock for
rfcomm_dev_state_change because just locking "d->state = BT_CLOSED;"
is enough.

'rfcomm connect' will trigger lockdep warnings which is caused by
locking diffrent kinds of bluetooth sockets at the same time.
So using sub-classes per AF_BLUETOOTH sub-type for lockdep.
Thanks for the hints from dave jones.

rose_release() doesn't release sockets properly, e.g. it skips
sock_orphan(), so OOPSes are triggered in sock_def_write_space(),
which was observed especially while ROSE skbs were kfreed from
ax25_frames_acked(). There is also sock_hold() and lock_sock() added -
similarly to ax25_release(). Thanks to Bernard Pidoux for substantial
help in debugging this problem.

ieee80211_sta_work is disabled while network interface
is down. Therefore, if you configure wireless parameters
before bringing the interface up, these configurations are
not yet effective and association fails.
A workaround from userspace is calling a command like
'iwconfig wlan0 ap any' after the interface is brought up.
To fix this behaviour, trigger execution of ieee80211_sta_work from
ieee80211_open when in STA or IBSS mode.

Don't allocate useless extra payload.
Cleanup magic numbers.

In ip6_mc_input(), we need to check whether we have listener(s) for
the packet.
After commit ae7bf20a6316272acfcaef5d265b18aaa54b41e4, all packets
for multicast destinations are delivered to upper layer if
IFF_PROMISC or IFF_ALLMULTI is set.
In fact, bug was rather ancient; the original (before the commit)
intent of the dev->flags check was to skip the ipv6_chk_mcast_addr()
call, assuming L2 filters packets appropriately, but it was even not
true.
Let's explicitly check our multicast list.
