      Pull signal bugfix from Eric Biederman:
 "When making the generic support for SIGEMT conditional on the presence
  of SIGEMT I made a typo that causes it to fail to activate. It was
  noticed comparatively quickly but the bug report just made it to me
  today"

      signal: Fix name of SIGEMT in #if defined() check · c3aff086
      Andrew Clayton authored 
      Commit cc731525 ("signal: Remove kernel interal si_code magic")
added a check for SIGMET and NSIGEMT being defined. That SIGMET should
in fact be SIGEMT, with SIGEMT being defined in
arch/{alpha,mips,sparc}/include/uapi/asm/signal.h

This was actually pointed out by BenHutchings in a lwn.net comment
here https://lwn.net/Comments/734608/

      x86/mm: fix use-after-free of vma during userfaultfd fault · cb0631fd
      Vlastimil Babka authored 
      Syzkaller with KASAN has reported a use-after-free of vma->vm_flags in
__do_page_fault() with the following reproducer:

  mmap(&(0x7f0000000000/0xfff000)=nil, 0xfff000, 0x3, 0x32, 0xffffffffffffffff, 0x0)
  mmap(&(0x7f0000011000/0x3000)=nil, 0x3000, 0x1, 0x32, 0xffffffffffffffff, 0x0)
  r0 = userfaultfd(0x0)
  ioctl$UFFDIO_API(r0, 0xc018aa3f, &(0x7f0000002000-0x18)={0xaa, 0x0, 0x0})
  ioctl$UFFDIO_REGISTER(r0, 0xc020aa00, &(0x7f0000019000)={{&(0x7f0000012000/0x2000)=nil, 0x2000}, 0x1, 0x0})
  r1 = gettid()
  syz_open_dev$evdev(&(0x7f0000013000-0x12)="2f6465762f696e7075742f6576656e742300", 0x0, 0x0)
  tkill(r1, 0x7)

The vma should be pinned by mmap_sem, but handle_userfault() might (in a
return to userspace scenario) release it and then acquire again, so when
we return to __do_page_fault() (with other result than VM_FAULT_RETRY),
the vma might be gone.

Specifically, per Andrea the scenario is
 "A return to userland to repeat the page fault later with a
  VM_FAULT_NOPAGE retval (potentially after handling any pending signal
  during the return to userland). The return to userland is identified
  whenever FAULT_FLAG_USER|FAULT_FLAG_KILLABLE are both set in
  vmf->flags"

However, since commit a3c4fb7c ("x86/mm: Fix fault error path using
unsafe vma pointer") there is a vma_pkey() read of vma->vm_flags after
that point, which can thus become use-after-free.  Fix this by moving
the read before calling handle_mm_fault().

      ide:ide-cd: fix kernel panic resulting from missing scsi_req_init · 79d73346
      Hongxu Jia authored 
      Since we split the scsi_request out of struct request, while the
standard prep_rq_fn builds 10 byte cmds, it missed to invoke
scsi_req_init() to initialize certain fields of a scsi_request
structure (.__cmd[], .cmd, .cmd_len and .sense_len but no other
members of struct scsi_request).

An example panic on virtual machines (qemu/virtualbox) to boot
from IDE cdrom:

      tcp: fix tcp_mtu_probe() vs highest_sack · 2b7cda9c
      Eric Dumazet authored 
      Based on SNMP values provided by Roman, Yuchung made the observation
that some crashes in tcp_sacktag_walk() might be caused by MTU probing.

Looking at tcp_mtu_probe(), I found that when a new skb was placed
in front of the write queue, we were not updating tcp highest sack.

If one skb is freed because all its content was copied to the new skb
(for MTU probing), then tp->highest_sack could point to a now freed skb.

Bad things would then happen, including infinite loops.

This patch renames tcp_highest_sack_combine() and uses it
from tcp_mtu_probe() to fix the bug.

Note that I also removed one test against tp->sacked_out,
since we want to replace tp->highest_sack regardless of whatever
condition, since keeping a stale pointer to freed skb is a recipe
for disaster.

Fixes: a47e5a98 ("[TCP]: Convert highest_sack to sk_buff to allow direct access")

3) Fix GSO for a IPsec, GRE tunnel combination.
   We reset the encapsulation field at the skb
   too erly, as a result GRE does not segment
   GSO packets. Fix this by resetting the the
   encapsulation field right before the
   transformation where the inner headers get
   invalid.

Please pull or let me know if there are problems.

      mlxsw: reg: Add high and low temperature thresholds · 62b0e924
      Ido Schimmel authored 
      The ASIC has the ability to generate events whenever a sensor indicates
the temperature goes above or below its high or low thresholds,
respectively.

In new firmware versions the firmware enforces a minimum of 5
degrees Celsius difference between both thresholds. Make the driver
conform to this requirement.

Note that this is required even when the events are disabled, as in
certain systems interrupts are generated via GPIO based on these
thresholds.

      net: hns: set correct return value · d2083d0e
      Pan Bian authored 
      The function of_parse_phandle() returns a NULL pointer if it cannot
resolve a phandle property to a device_node pointer. In function
hns_nic_dev_probe(), its return value is passed to PTR_ERR to extract
the error code. However, in this case, the extracted error code will
always be zero, which is unexpected.

      net: lapbether: fix double free · 7db8874a
      Pan Bian authored 
      The function netdev_priv() returns the private data of the device. The
memory to store the private data is allocated in alloc_netdev() and is
released in netdev_free(). Calling kfree() on the return value of
netdev_priv() after netdev_free() results in a double free bug.

      John Fastabend authored 
      Now that SK_REDIRECT is no longer a valid return code. Remove it
from the UAPI completely. Then do a namespace remapping internal
to sockmap so SK_REDIRECT is no longer externally visible.

Patchs primary change is to do a namechange from SK_REDIRECT to
__SK_REDIRECT

      net: phy: marvell: Only configure RGMII delays when using RGMII · 14fc0aba
      Andrew Lunn authored 
      The fix 5987feb3 ("net: phy: marvell: logical vs bitwise OR typo")
uncovered another bug in the Marvell PHY driver, which broke the
Marvell OpenRD platform. It relies on the bootloader configuring the
RGMII delays and does not specify a phy-mode in its device tree.  The
PHY driver should only configure RGMII delays if the phy mode
indicates it is using RGMII. Without anything in device tree, the
mv643xx Ethernet driver defaults to GMII.

Kalle Valo says:

====================
wireless-drivers fixes for 4.14

The most important here is the security vulnerabitility fix for
ath10k.

ath10k

* fix security vulnerability with missing PN check on certain hardware

* revert ath10k napi fix as it caused regressions on QCA6174

wcn36xx

* remove unnecessary rcu_read_unlock() from error path
