3d861f6610 net: fix secpath kmemleak
Mike Kazantsev found 3.5 kernels and beyond were leaking memory,
and tracked the faulty commit to a1c7fff7e1 ("net:
netdev_alloc_skb() use build_skb()")

While this commit seems fine, it uncovered a bug introduced
in commit bad43ca832 ("net: introduce skb_try_coalesce()), in function
kfree_skb_partial()"):

If head is stolen, we free the sk_buff,
without removing references on secpath (skb->sp).

So IPsec + IP defrag/reassembly (using skb coalescing), or
TCP coalescing could leak secpath objects.

Fix this bug by calling skb_release_head_state(skb) to properly
release all possible references to linked objects.

John W. Linville says:

====================
This is a batch of fixes intended for the 3.7 stream.

Dan Carpenter brings a fix for a simple signedness bug that could
prevent the proper termination of a loop.

Felix Fietkau found a few more places that need to use
ieee80211_free_txskb for properly releasing SKBs used by mac80211.

Franky Lin offers a pair of brcmfmac fixes, both fixing simple state
reporting errors.

Hante Meuleman corrects an error reporting case that wasn't handling
all types of errors properly.

Johan Hedberg offers a fix for an issue discovered at the Bluetooth
UnPlug Fest.  Gustavo says "the patch fixes a failure to pair with
devices that support the LE Secure Connections feature."

Johannes Berg sends an iwlwifi fix to handle a message type that
is too large for the normal command mechanism.  He also provides a
mac80211 fix to use HT20 channels when HT40 channels are not permitted.

Jouni Malinen offers a mac80211 fix for a masking error that was
incorrectly marking some frames.

Piotr Haber provides a fix to make sure bcma devices are unregistered
properly.

Stanislav Yakovlev gives us a fix for a panic in the ipw2200 driver.

Stanislaw Gruszka sends a pair of fixes: one prevents a mismatch on
connection states between cfg80211 and mac80211; the other prevents
some frame corruption related to handling encryption.

a3374c42aa tcp: fix FIONREAD/SIOCINQ
tcp_ioctl() tries to take into account if tcp socket received a FIN
to report correct number bytes in receive queue.

But its flaky because if the application ate the last skb,
we return 1 instead of 0.

Correct way to detect that FIN was received is to test SOCK_DONE.

6d772ac557 netlink: use kfree_rcu() in netlink_release()
On some suspend/resume operations involving wimax device, we have
noticed some intermittent memory corruptions in netlink code.

Stéphane Marchesin tracked this corruption in netlink_update_listeners()
and suggested a patch.

It appears netlink_release() should use kfree_rcu() instead of kfree()
for the listeners structure as it may be used by other cpus using RCU
protection.

netlink_release() must set to NULL the listeners pointer when
it is about to be freed.

Also have to protect netlink_update_listeners() and
netlink_has_listeners() if listeners is NULL.

Add a nl_deref_protected() lockdep helper to properly document which
locks protects us.

7f112af40f batman-adv: Fix broadcast packet CRC calculation
So far the crc16 checksum for a batman-adv broadcast data packet, received
on a batman-adv hard interface, was calculated over zero bytes of its
content leading to many incoming broadcast data packets wrongly being
dropped (60-80% packet loss).

This patch fixes this issue by calculating the crc16 over the actual,
complete broadcast payload.

The issue is a regression introduced by
("batman-adv: add broadcast duplicate check").

Pull misc UAPI fixes from David Howells:
 "They do a number of things:

  (1) Import a patch from Catalin Marinas to extend the generic-y in
      Kbuild facility to uapi directories.

  (2) Make arch/tile's ucontext.h file use (1) and remove the header-y
      line from the kernel internal side of things.

  (3) Remove some now-empty conditional bits from include/linux/Kbuild.
      The contents got moved to the UAPI side of things along with new
      conditionals.

  (4) Deal with now-empty files:

     (a) Empty Kbuild files under include/ get removed.

     (b) Empty Kbuild files under arch/ get comments to hold them as
         they are likely to end up with generic-y or genhdr-y lines.
         Deleting them appears to work if we want to go that route.

     (c) Put a comment into uapi/asm-generic/kvm_para.h to prevent the
         patch program from deleting that, and made the arches with
         empty kvm_para.h uapi files use that instead of having their
         own files.

     (d) Put comments into four other empty uapi/ headers to prevent the
         patch program from deleting them.

  A question: Is this the right way to deal with the now-empty Kbuild
  files?

  The ones under include/ are unlikely to be used - even for generated
  files, I think - so getting rid of them is probably okay.  Once all
  the bits are in, we can probably remove all the Kbuild files under
  include/ that aren't also under include/uapi/.

  The ones under arch/ are more of an issue because of the potential for
  generic-y and genhdr-y."

3a40414f82 mac80211: connect with HT20 if HT40 is not permitted
Some changes to fix issues with HT40 APs in Korea
and follow-up changes to allow using HT40 even if
the local regulatory database disallows it caused
issues with iwlwifi (and could cause issues with
other devices); iwlwifi firmware would assert if
you tried to connect to an AP that has an invalid
configuration (e.g. using HT40- on channel 140.)

Fix this, while avoiding the "Korean AP" issue by
disabling HT40 and advertising HT20 to the AP
when connecting.

Make uapi/asm-generic/kvm_para.h non-empty by addition of a comment to stop
the patch program from deleting it when it creates it.

Then delete empty arch-specific uapi/asm/kvm_para.h files and tell the Kbuild

Should this perhaps instead be a #warning or #error that the facility is
unsupported on this arch?

4c7b279c1a UAPI: Place comments in empty arch Kbuilds to make them non-empty
Place comments in:

	arch/mips/include/asm/Kbuild
	arch/tile/include/arch/Kbuild

to make them non-empty so that the patch program doesn't remove them when it
reduces them to nothing.

Possibly they should be just deleted, but it's possible that they'll acquire
generic-y or genhdr-y lines in future, so I'm keeping them around for the
moment.

Note that MIPS will compile happily if the file is deleted instead.  I haven't
tested TILE, but I suspect it will be the same there.

64d7155cdf UAPI: Remove empty non-UAPI Kbuild files
Remove non-UAPI Kbuild files that have become empty as a result of UAPI
disintegration.  They used to have only header-y lines in them and those have
now moved to the Kbuild files in the corresponding uapi/ directories.

Possibly these should not be removed but rather have a comment inserted to say
they are intentionally left blank.  This would make it easier to add generated
header lines in future without having to restore the infrastructure.

Note that at this point not all the UAPI disintegration parts have been merged,
so it is likely that more empty Kbuild files will turn up.

It is probably necessary to make the files non-empty to prevent the patch
program from automatically deleting them when it reduces them to nothing.

886927e4a4 UAPI: Make uapi/linux/irqnr.h non-empty
uapi/linux/irqnr.h was emitted by the UAPI disintegration script as an empty
file because the parent linux/irqnr.h had no UAPI stuff in it, despite being
marked with "header-y".

Unfortunately, the patch program deletes the empty file when applying a kernel
patch.

It's not clear why this file is part of the UAPI at all.  Looking in:

	/usr/include/linux/irqnr.h

there's nothing there but a header reinclusion guard and a comment.

So just stick a comment in there as a placeholder.

Without this, if the kernel is fabricated from, say, a tarball and a patch, you
can get this error when building x86_64 or usermode Linux (and probably
others):

Torsten Luettgert bisected TEE regression starting with commit
f8126f1d51 (ipv4: Adjust semantics of rt->rt_gateway.)

The problem is that it tries to ARP-lookup the original destination
address of the forwarded packet, not the address of the gateway.

Fix this using FLOWI_FLAG_KNOWN_NH Julian added in commit
c92b96553a (ipv4: Add FLOWI_FLAG_KNOWN_NH), so that known
nexthop (info->gw.ip) has preference on resolving.

0c552e5fb9 FRV: Fix linux/elf-fdpic.h
It seems I accidentally switched the guard on linux/elf-fdpic.h from #ifdef
__KERNEL__ to #ifndef __KERNEL__ when attempting to expand the guarded region
to cover the elf_fdpic_params struct when doing the UAPI split - with the
result that the struct became unavailable to kernel code.

Move incorrectly guarded bits back to the kernelspace header.

Whilst we're at it, the __KERNEL__ guards can be deleted as they're no longer
necessary.
