      由 David S. Miller 提交于 
      Merge branch 'for-davem' of git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless into wireless

John W. Linville says:

====================
Here are some more fixes intended for the 3.9 stream...

Regarding the mac80211 bits, Johannes says:

"I had changed the idle handling to simplify it, but broken the
sequencing of commands, at least for ath9k-htc, one patch restores the
sequence. The other patch fixes a crash Jouni found while stress-testing
the remain-on-channel code, when an item is deleted the work struct can
run twice and crash the second time."

As for the iwlwifi bits, Johannes says:

"The only fix here is to the passive-no-RX firmware regulatory
enforcement driver support code to not drop auth frames in quick
succession, leading to not being able to connect to APs on passive
channels in certain circumstances."

Don't forget the NFC bits, about which Samuel says:

"This time we have:

- A crash fix for when a DGRAM LLCP socket is listening while the NFC adapter
  is physically removed.
- A potential double skb free when the LLCP socket receive queue is full.
- A fix for properly handling multiple and consecutive LLCP connections, and
  not trash the socket ack log.
- A build failure for the MEI microread physical layer, now that the MEI bus
  APIs have been merged into char-misc-next."

On top of that, Stone Piao provides an mwifiex fix to avoid accessing
beyond the end of a buffer.

      由 Linus Torvalds 提交于 
      Pull ARM SoC bug fixes from Arnd Bergmann:
 "After a quiet set of fixes for 3.9-rc4, a lot of people woke up and
  sent urgent fixes for 3.9.  I pushed back on a number of them that got
  deferred to 3.10, but these are the ones that seemed important.

  Regression in 3.9:

   - Multiple regressions in OMAP2+ clock cleanup
   - SH-Mobile frame buffer bug fix that merged here because of
     maintainer MIA
   - ux500 prcmu changes broke DT booting
   - MMCI duplicated regulator setup on ux500
   - New ux500 clock driver broke ethernet on snowball
   - Local interrupt driver for mvebu broke ethernet
   - MVEBU GPIO driver did not get set up right on Orion DT
   - incorrect interrupt number on Orion crypto for DT

  Long-standing bugs, including candidates for stable:

   - Kirkwood MMC needs to disable invalid card detect pins
   - MV SDIO pinmux was wrong on Mirabox
   - GoFlex Net board file needs to set NAND chip delay
   - MSM timer restart race
   - ep93xx early debug code broke in 3.7
   - i.MX CPU hotplug race
   - Incorrect clock setup for OMAP1 USB
   - Workaround for bad clock setup by some old OMAP4 boot loaders
   - Static I/O mappings on cns3xxx since 3.2"

      loop: prevent bdev freeing while device in use · c1681bf8
      由 Anatol Pomozov 提交于 
      struct block_device lifecycle is defined by its inode (see fs/block_dev.c) -
block_device allocated first time we access /dev/loopXX and deallocated on
bdev_destroy_inode. When we create the device "losetup /dev/loopXX afile"
we want that block_device stay alive until we destroy the loop device
with "losetup -d".

But because we do not hold /dev/loopXX inode its counter goes 0, and
inode/bdev can be destroyed at any moment. Usually it happens at memory
pressure or when user drops inode cache (like in the test below). When later in
loop_clr_fd() we want to use bdev we have use-after-free error with following
stack:

BUG: unable to handle kernel NULL pointer dereference at 0000000000000280
  bd_set_size+0x10/0xa0
  loop_clr_fd+0x1f8/0x420 [loop]
  lo_ioctl+0x200/0x7e0 [loop]
  lo_compat_ioctl+0x47/0xe0 [loop]
  compat_blkdev_ioctl+0x341/0x1290
  do_filp_open+0x42/0xa0
  compat_sys_ioctl+0xc1/0xf20
  do_sys_open+0x16e/0x1d0
  sysenter_dispatch+0x7/0x1a

To prevent use-after-free we need to grab the device in loop_set_fd()
and put it later in loop_clr_fd().

The issue is reprodusible on current Linus head and v3.3. Here is the test:

  dd if=/dev/zero of=loop.file bs=1M count=1
  while [ true ]; do
    losetup /dev/loop0 loop.file
    echo 2 > /proc/sys/vm/drop_caches
    losetup -d /dev/loop0
  done

[ Doing bdgrab/bput in loop_set_fd/loop_clr_fd is safe, because every
  time we call loop_set_fd() we check that loop_device->lo_state is
  Lo_unbound and set it to Lo_bound If somebody will try to set_fd again
  it will get EBUSY.  And if we try to loop_clr_fd() on unbound loop
  device we'll get ENXIO.

  loop_set_fd/loop_clr_fd (and any other loop ioctl) is called under
  loop_device->lo_ctl_mutex. ]

      sh_eth: workaround for spurious ECI interrupt · 3893b273
      由 Sergei Shtylyov 提交于 
      At least on Renesas R8A7778, EESR.ECI interrupt seems to fire regardless of its
mask in EESIPR register. I can 100% reproduce it with the following scenario:
target is booted with 'ip=on' option, and so IP-Config opens SoC Ether device
but doesn't get a proper reply and then succeeds with on-board SMC chip; then
I login and try to bring up the SoC Ether device with 'ifconfig', and I get
an ECI interrupt once request_irq() is called by sh_eth_open() (while interrupt
mask in EESIPR register is all 0), if that interrupt is accompanied by a pending
EESR.FRC (frame receive completion) interrupt, I get kernel oops in sh_eth_rx()
because sh_eth_ring_init() hasn't been called yet!

The solution I worked out is the following: in sh_eth_interrupt(), mask the
interrupt status from EESR register with the interrupt mask from EESIPR register
in order not to handle the disabled interrupts -- but forcing EESIPR.M_ECI bit
in this mask set because we always need to fully handle EESR.ECI interrupt in
sh_eth_error() in order to quench it (as it doesn't get cleared by just writing
1 to the this bit as all the other interrupts).

While at it, remove unneeded initializer for 'intr_status' variable and give it
*unsigned long* type, matching the type of sh_eth_read()'s result; fix comment.

      sh_eth: fix handling of no LINK signal · 1e1b812b
      由 Sergei Shtylyov 提交于 
      The code handling the absent LINK signal (or the absent PSR register -- which
reflects the state of this signal) is quite naive and has probably never really
worked.  It's probably enough to say that this code is executed only on the LINK
change interrupt (sic!) but even if we actually have the signal and choose to
ignore it (it might be connected to PHY's link/activity LED output as on the
Renesas BOCK-W board), sh_eth_adjust_link() on which this code relies to update
'mdp->link' gets executed later than the LINK change interrupt where it is
checked, and so RX/TX never get enabled via ECMR register.

So, ignore the LINK changed interrupt iff LINK signal is absent (or just chosen
not to be used) or PSR register is absent, and enable/disable RX/TX directly in
sh_eth_adjust_link() in this case.
