be33690d8f [XFRM]: Fix aevent related crash
When xfrm_user isn't loaded xfrm_nl is NULL, which makes IPsec crash because
xfrm_aevent_is_on passes the NULL pointer to netlink_has_listeners as socket.
A second problem is that the xfrm_nl pointer is not cleared when the socket
is releases at module unload time.

Protect references of xfrm_nl from outside of xfrm_user by RCU, check
that the socket is present in xfrm_aevent_is_on and set it to NULL
when unloading xfrm_user.

15d99e02ba [TCP]: sysctl to allow TCP window > 32767 sans wscale
Back in the dark ages, we had to be conservative and only allow 15-bit
window fields if the window scale option was not negotiated.  Some
ancient stacks used a signed 16-bit quantity for the window field of
the TCP header and would get confused.

Those days are long gone, so we can use the full 16-bits by default
now.

There is a sysctl added so that we can still interact with such old
stacks

59f1741e54 [TG3]: netif_carrier_off runs too early; could still be queued when init fails
Move the netif_carrier_off() call from tg3_init_one()->
tg3_init_link_config() to tg3_open() as is the convention for most other
network drivers.

I was getting a panic after a tg3 device failed to initialize due to DMA
failure.  The oops pointed to the link watch queue with spinlock debugging
enabled.  Without spinlock debugging, the Oops didn't occur.

I suspect that the link event was getting queued but not executed until
after the DMA test had failed and the device was freed.  The link event was
then operating on freed memory, which could contain anything.  With this
patch applied, the Oops no longer occurs.

[ Based upon feedback from Michael Chan, we move netif_carrier_off()
  to the end of tg3_init_one() instead of moving it to tg3_open() -DaveM ]

05790c6456 [TIPC]: Remove inlines from *.c
With reference to latest discussions on linux-kernel with respect to
inline here is a patch for tipc to remove all inlines as used in
the .c files. See also chapter 14 in Documentation/CodingStyle.

Before:
   text        data     bss     dec     hex filename
 102990        5292    1752  110034   1add2 tipc.o

Now:
   text        data     bss     dec     hex filename
 101190        5292    1752  108234   1a6ca tipc.o

This is a nice text size reduction which will improve icache usage.
In some cases bigger (> 4 lines) functions where declared inline
and used in many places, they are most probarly no longer inlined by gcc
resulting in the size reduction.
There are several one liners that no longer are declared inline, but gcc
should inline these just fine without the inline hint.

With this patch applied one warning is added about an unused static
function - that was hidded by utilising inline before.
The function in question were kept so this patch is solely a
inline removal patch.

driver stashes some info in the neighbour structure (the results of
the second-stage lookup from ARP results to real link-level path), and
it uses neigh->ops->destructor to get a callback so it can clean up
this extra info when a neighbour is freed.  We've run into problems
with this: since the destructor is in an ops field that is shared
between neighbours that may belong to different net devices, there's
no way to set/clear it safely.

The following patch moves this field to neigh_parms where it can be
safely set, together with its twin neigh_setup.  Two additional
patches in the patch series update ipoib to use this new interface.

6146e6a43b [PKTGEN]: Removes thread_{un,}lock() macros.
As suggested by Arnaldo, this patch replaces the
thread_lock()/thread_unlock() by directly calls to
mutex_lock()/mutex_unlock().

This change makes the code a bit more readable, and the direct calls
are used everywhere in the kernel.

253aa11578 [IPSEC] xfrm_user: Kill PAGE_SIZE check in verify_sec_ctx_len()
First, it warns when PAGE_SIZE >= 64K because the ctx_len
field is 16-bits.

Secondly, if there are any real length limitations it can
be verified by the security layer security_xfrm_state_alloc()
call.

0bc6d90b82 [TCP] H-TCP: Account for delayed-ACKs
Account for delayed-ACKs in H-TCP.

Delayed-ACKs cause H-TCP to be less aggressive than its design calls
for. It is especially true when the receiver is a Linux machine where
the average delayed ack is over 3 packets with values of 7 not unheard
of.
