Tom Parkin f8ccac0e44 l2tp: put tunnel socket release on a workqueue
To allow l2tp_tunnel_delete to be called from an atomic context, place the
tunnel socket release calls on a workqueue for asynchronous execution.

Tunnel memory is eventually freed in the tunnel socket destructor.

David S. Miller 188d1f76d0 Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Conflicts:
	drivers/net/ethernet/intel/e1000e/ethtool.c
	drivers/net/vmxnet3/vmxnet3_drv.c
	drivers/net/wireless/iwlwifi/dvm/tx.c
	net/ipv6/route.c

The ipv6 route.c conflict is simple, just ignore the 'net' side change
as we fixed the same problem in 'net-next' by eliminating cached
neighbours from ipv6 routes.

The e1000e conflict is an addition of a new statistic in the ethtool
code, trivial.

The vmxnet3 conflict is about one change in 'net' removing a guarding
conditional, whilst in 'net-next' we had a netdev_info() conversion.

The iwlwifi conflict is dealing with a WARN_ON() conversion in
'net-next' vs. a revert happening in 'net'.

Or Gerlitz f97b4b5d46 mlx4_core: Fix advertisement of wrong PF context behaviour
Commit 08ff32352d ("mlx4: 64-byte CQE/EQE support") introduced a
regression where older guest VF drivers failed to load even when
64-byte EQEs/CQEs are disabled, since the PF wrongly advertises the
new context behaviour anyway.  The failure looks like:

    mlx4_core 0000:00:07.0: Unknown pf context behaviour
    mlx4_core 0000:00:07.0: Failed to obtain slave caps
    mlx4_core: probe of 0000:00:07.0 failed with error -38

Fix this by basing this advertisement on dev->caps.flags, which is the
operational capabilities used by the QUERY_FUNC_CAP command wrapper
(dev_cap->flags holds the firmware capabilities).

Shlomo Pongratz 7e5a90c25f IPoIB: Fix crash due to skb double destruct
After commit b13912bbb4 ("IPoIB: Call skb_dst_drop() once skb is
enqueued for sending"), using connected mode and running multithreaded
iperf for long time, ie

    iperf -c <IP> -P 16 -t 3600

results in a crash.

After the above-mentioned patch, the driver is calling skb_orphan() and
skb_dst_drop() after calling post_send() in ipoib_cm.c::ipoib_cm_send()
(also in ipoib_ib.c::ipoib_send())

The problem with this is, as is written in a comment in both routines,
"it's entirely possible that the completion handler will run before we
execute anything after the post_send()."  This leads to running the
skb cleanup routines simultaneously in two different contexts.

The solution is to always perform the skb_orphan() and skb_dst_drop()
before queueing the send work request.  If an error occurs, then it
will be no different than the regular case where dev_free_skb_any() in
the completion path, which is assumed to be after these two routines.

Arnd Bergmann 275aaa6833 samples/seccomp: be less stupid about cross compiling
The seccomp filters are currently built for the build host, not for the
machine that they are going to run on, but they are also built for with
the -m32 flag if the kernel is built for a 32 bit machine, both of which
seems rather odd.

It broke allyesconfig on my machine, which is x86-64, but building for
32 bit ARM, with this error message:

  In file included from /usr/include/stdio.h:28:0,
                   from samples/seccomp/bpf-fancy.c:15:
  /usr/include/features.h:324:26: fatal error: bits/predefs.h: No such file or directory

because there are no 32 bit libc headers installed on this machine.  We
should really be building all the samples for the target machine rather
than the build host, but since the infrastructure for that appears to be
missing right now, let's be a little bit smarter and not pass the '-m32'
flag to the HOSTCC when cross- compiling.

Glauber Costa 91c777d867 memcg: fix typo in kmemcg cache walk macro
The macro for_each_memcg_cache_index contains a silly yet potentially
deadly mistake.  Although the macro parameter is _idx, the loop tests
are done over i, not _idx.

This hasn't generated any problems so far, because all users use i as a
loop index.  However, while playing with an extension of the code I
ended using another loop index and the compiler was quick to complain.

Unfortunately, this is not the kind of thing that testing reveals =(

Vyacheslav Dubeyko a9bae18954 nilfs2: fix fix very long mount time issue
There exists a situation when GC can work in background alone without
any other filesystem activity during significant time.

The nilfs_clean_segments() method calls nilfs_segctor_construct() that
updates superblocks in the case of NILFS_SC_SUPER_ROOT and
THE_NILFS_DISCONTINUED flags are set.  But when GC is working alone the
nilfs_clean_segments() is called with unset THE_NILFS_DISCONTINUED flag.
As a result, the update of superblocks doesn't occurred all this time
and in the case of SPOR superblocks keep very old values of last super
root placement.

SYMPTOMS:

Trying to mount a NILFS2 volume after SPOR in such environment ends with
very long mounting time (it can achieve about several hours in some
cases).

REPRODUCING PATH:

1. It needs to use external USB HDD, disable automount and doesn't
   make any additional filesystem activity on the NILFS2 volume.

2. Generate temporary file with size about 100 - 500 GB (for example,
   dd if=/dev/zero of=<file_name> bs=1073741824 count=200).  The size of
   file defines duration of GC working.

3. Then it needs to delete file.

4. Start GC manually by means of command "nilfs-clean -p 0".  When you
   start GC by means of such way then, at the end, superblocks is updated
   by once.  So, for simulation of SPOR, it needs to wait sometime (15 -
   40 minutes) and simply switch off USB HDD manually.

5. Switch on USB HDD again and try to mount NILFS2 volume.  As a
   result, NILFS2 volume will mount during very long time.

REPRODUCIBILITY: 100%

FIX:

This patch adds checking that superblocks need to update and set
THE_NILFS_DISCONTINUED flag before nilfs_clean_segments() call.

Paul Gortmaker 7c1e7e99ab gianfar: dont conditionally alloc Rx/Err irq structs
Commit ee873fda3b

    "gianfar: Pack struct gfar_priv_grp into three cachelines"

causes the following null dereference at driver init on sbc8548:

   libphy: Freescale PowerQUICC MII Bus: probed
   Unable to handle kernel paging request for data at address 0x00000000
   Faulting instruction address: 0xc01d6a38
   Oops: Kernel access of bad area, sig: 11 [#1]
   [...]
   NIP [c01d6a38] gfar_parse_group+0x228/0x280
   LR [c01d6a34] gfar_parse_group+0x224/0x280
   Call Trace:
   [ef82dd60] [c01d6a34] gfar_parse_group+0x224/0x280 (unreliable)
   [ef82dd90] [c01d73a4] gfar_probe+0x284/0xfe0

The reason is that the commit also changed the allocation of the
Rx and error handling irq structs to be skipped for !MQ_MG_MODE.
In the !MQ_MG_MODE case, only the Tx irq struct is allocated.

Digging further, we see that MQ_MG_MODE is set only if we find
the OF compatible string "fsl,etsec2".

A quick grep in the dts directory shows lots of boards that support
Rx/Tx/Err, but without this specific compat string.  And hence they
go after the unallocated Rx/Error structs and cause the above oops.

Hence such a change can not be deployed until all the dts files
are updated and sufficiently deployed.  Further, the optimization
is of limited value, since the kmalloc'd struct in question has only
a single unsigned int, and an (IFNAMSIZ + 6) sized string.

Note that no changes to the freeing code are needed here, as it
already did an unconditional free of Rx/Tx/Error gfar_irqinfo.

Arend van Spriel 7b2385b953 brcmsmac: rework of mac80211 .flush() callback operation
This patch addresses a long standing issue of the driver with the
mac80211 .flush() callback. Since implementing the .flush() callback
a number of issues have been fixed, but a WARN_ON_ONCE() was still
triggered because the timeout on the flush could still occur.

This patch changes the awkward design using msleep() into one using
a waitqueue. The waiting flush() context will kick the transmit dma
when it is idle and the timeout used waiting for the event is set
to 500 ms. Worst case there can be 64 frames outstanding for transmit
in the driver. At a rate of 1Mbps that would take 1.5 seconds assuming
MTU is 1500 bytes and ignoring retries. The WARN_ON_ONCE() is also
removed as this was put in to indicate the flush timeout as a reason
for the driver to stall. That was not happening since fixing endless
AMPDU retries with following upstream commit:

Larry Finger a5ffbe0a19 rtlwifi: Fix scheduling while atomic bug
Kernel commits 41affd5 and 6539306 changed the locking in rtl_lps_leave()
from a spinlock to a mutex by doing the calls indirectly from a work queue
to reduce the time that interrupts were disabled. This change was fine for
most systems; however a scheduling while atomic bug was reported in
https://bugzilla.redhat.com/show_bug.cgi?id=903881. The backtrace indicates
that routine rtl_is_special(), which calls rtl_lps_leave() in three places
was entered in atomic context. These direct calls are replaced by putting a
request on the appropriate work queue.
