7a84bd4664 sctp: translate network order to host order when users get a hmacid
Commit ed5a377d87 ("sctp: translate host order to network order when
setting a hmacid") corrected the hmacid byte-order when setting a hmacid.
but the same issue also exists on getting a hmacid.

We fix it by changing hmacids to host order when users get them with
getsockopt.

ca7f41a495 enic: increment devcmd2 result ring in case of timeout
Firmware posts the devcmd result in result ring. In case of timeout, driver
does not increment the current result pointer and firmware could post the
result after timeout has occurred. During next devcmd, driver would be
reading the result of previous devcmd.

Fix this by incrementing result even in case of timeout.

b7d987295c tg3: Fix for tg3 transmit queue 0 timed out when too many gso_segs
tg3_tso_bug() can hit a condition where the entire tx ring is not big
enough to segment the GSO packet. For example, if MSS is very small,
gso_segs can exceed the tx ring size. When we hit the condition, it
will cause tx timeout.

tg3_tso_bug() is called to handle TSO and DMA hardware bugs.
For TSO bugs, if tg3_tso_bug() cannot succeed, we have to drop the packet.
For DMA bugs, we can still fall back to linearize the SKB and let the
hardware transmit the TSO packet.

This patch adds a function tg3_tso_bug_gso_check() to check if there
are enough tx descriptors for GSO before calling tg3_tso_bug().
The caller will then handle the error appropriately - drop or
lineraize the SKB.

v2: Corrected patch description to avoid confusion.

5f74f82ea3 net:Add sysctl_max_skb_frags
Devices may have limits on the number of fragments in an skb they support.
Current codebase uses a constant as maximum for number of fragments one
skb can hold and use.
When enabling scatter/gather and running traffic with many small messages
the codebase uses the maximum number of fragments and may thereby violate
the max for certain devices.
The patch introduces a global variable as max number of fragments.

9cf7490360 tcp: do not drop syn_recv on all icmp reports
Petr Novopashenniy reported that ICMP redirects on SYN_RECV sockets
were leading to RST.

This is of course incorrect.

A specific list of ICMP messages should be able to drop a SYN_RECV.

For instance, a REDIRECT on SYN_RECV shall be ignored, as we do
not hold a dst per SYN_RECV pseudo request.

92e6edd685 regmap: mmio: Revert to v4.4 endianness handling
Commit 29bb45f25f (regmap-mmio: Use native endianness for read/write)
 attempted to fix some long standing bugs in the MMIO implementation for
 big endian systems caused by duplicate byte swapping in both regmap and
 readl()/writel() which affected MIPS systems as when they are in big
 endian mode they flip the endianness of all registers in the system, not
 just the CPU.  MIPS systems had worked around this by declaring regmap
 using IPs as little endian which is inaccurate, unfortunately the issue
 had not been reported.
 
 Sadly the fix makes things worse rather than better.  By changing the
 behaviour to match the documentation it caused behaviour changes for
 other IPs which broke them and by using the __raw I/O accessors to avoid
 the endianness swapping in readl()/writel() it removed some memory
 ordering guarantees and could potentially generate unvirtualisable
 instructions on some architectures.
 
 Unfortunately sorting out all this mess in any half way sensible fashion
 was far too invasive to go in during an -rc cycle so instead let's go
 back to the old broken behaviour for v4.5, the better fixes are already
 queued for v4.6.  This does mean that we keep the broken MIPS DTs for
 another release but that seems the least bad way of handling the
 situation.

415e3d3e90 unix: correctly track in-flight fds in sending process user_struct
The commit referenced in the Fixes tag incorrectly accounted the number
of in-flight fds over a unix domain socket to the original opener
of the file-descriptor. This allows another process to arbitrary
deplete the original file-openers resource limit for the maximum of
open files. Instead the sending processes and its struct cred should
be credited.

To do so, we add a reference counted struct user_struct pointer to the
scm_fp_list and use it to account for the number of inflight unix fds.

The ACPI match module is common to all three drivers, HSW, SKL

can be inbuilt in a single image

ddce57a6f0 ALSA: dummy: Implement timer backend switching more safely
Currently the selected timer backend is referred at any moment from
the running PCM callbacks.  When the backend is switched, it's
possible to lead to inconsistency from the running backend.  This was
pointed by syzkaller fuzzer, and the commit [7ee96216c3: ALSA:
dummy: Disable switching timer backend via sysfs] disabled the dynamic
switching for avoiding the crash.

This patch improves the handling of timer backend switching.  It keeps
the reference to the selected backend during the whole operation of an
opened stream so that it won't be changed by other streams.

Together with this change, the hrtimer parameter is reenabled as
writable now.

NOTE: this patch also turned out to fix the still remaining race.
Namely, ops was still replaced dynamically at dummy_pcm_open:

  static int dummy_pcm_open(struct snd_pcm_substream *substream)
  {
  ....
          dummy->timer_ops = &dummy_systimer_ops;
          if (hrtimer)
                  dummy->timer_ops = &dummy_hrtimer_ops;

Since dummy->timer_ops is common among all streams, and when the
replacement happens during accesses of other streams, it may lead to a
crash.  This was actually triggered by syzkaller fuzzer and KASAN.

This patch rewrites the code not to use the ops shared by all streams
any longer, too.

c17dfb019d ARM: SoC fixes for v4.5-rc
The first real batch of fixes for this release cycle, so there are a few more
 than usual.
 
 Most of these are fixes and tweaks to board support (DT bugfixes, etc). I've
 also picked up a couple of small cleanups that seemed innocent enough that
 there was little reason to wait (const/__initconst and Kconfig deps).
 
 Quite a bit of the changes on OMAP were due to fixes to no longer write to
 rodata from assembly when ARM_KERNMEM_PERMS was enabled, but there were also
 other fixes.
 
 Kirkwood had a bunch of gpio fixes for some boards. OMAP had RTC fixes
 on OMAP5, and Nomadik had changes to MMC parameters in DT.
 
 All in all, mostly the usual mix of various fixes.

cb43285ff7 qla2xxx: Fix stale pointer access.
[ Upstream Commit 84e32a06f4 ]

Commit 84e32a0 ("qla2xxx: Use pci_enable_msix_range() instead of
pci_enable_msix()") introduced a regression when target mode is enabled.
In qla24xx_enable_msix(), ha->max_rsp_queues was incorrectly set
to a value higher than the number of response queues allocated causing
an invalid dereference. Specifically here in qla2x00_init_rings():
    *rsp->in_ptr = 0;

Add additional check to make sure the pointer is valid. following

0633e12346 target/user: Fix cast from pointer to phys_addr_t
The uio_mem structure has a member that is a phys_addr_t, but can
be a number of other types too. The target core driver attempts
to assign a pointer from vmalloc() to it, by casting it to
phys_addr_t, but that causes a warning when phys_addr_t is longer
than a pointer:

drivers/target/target_core_user.c: In function 'tcmu_configure_device':
drivers/target/target_core_user.c:906:22: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast]

This adds another cast to uintptr_t to shut up the warning.
A nicer fix might be to have additional fields in uio_mem
for the different purposes, so we can assign a pointer directly.

310d3d314b target: Fix race with SCF_SEND_DELAYED_TAS handling
This patch fixes a race between setting of SCF_SEND_DELAYED_TAS
in transport_send_task_abort(), and check of the same bit in
transport_check_aborted_status().

It adds a __transport_check_aborted_status() version that is
used by target_execute_cmd() when se_cmd->t_state_lock is
held, and a transport_check_aborted_status() wrapper for
all other existing callers.

Also, it handles the case where the check happens before
transport_send_task_abort() gets called.  For this, go
ahead and set SCF_SEND_DELAYED_TAS early when necessary,
and have transport_send_task_abort() send the abort.
