David L Stevens 8266f5fcf0 sunvnet: only use connected ports when sending
The sunvnet driver doesn't check whether or not a port is connected when
transmitting packets, which results in failures if a port fails to connect
(e.g., due to a version mismatch). The original code also assumes
unnecessarily that the first port is up and a switch, even though there is
a flag for switch ports.

This patch only matches a port if it is connected, and otherwise uses the
switch_port flag to send the packet to a switch port that is up.

====================
pull-request: can 2014-07-25

this is a pull request of one patch for the net tree, hoping to get into the
3.16 release.

The patch by George Cherian fixes a regression in the c_can platform driver.
When using two interfaces the regression leads to a non function second
interface.

Andy Lutomirski 7209a75d20 x86_64/entry/xen: Do not invoke espfix64 on Xen
This moves the espfix64 logic into native_iret.  To make this work,
it gets rid of the native patch for INTERRUPT_RETURN:
INTERRUPT_RETURN on native kernels is now 'jmp native_iret'.

This changes the 16-bit SS behavior on Xen from OOPSing to leaking
some bits of the Xen hypervisor's RSP (I think).

[ hpa: this is a nonzero cost on native, but probably not enough to
  measure. Xen needs to fix this in their own code, probably doing
  something equivalent to espfix64. ]

Mikulas Patocka f960d2093f crypto: arm64-aes - fix encryption of unaligned data
cryptsetup fails on arm64 when using kernel encryption via AF_ALG socket.
See https://bugzilla.redhat.com/show_bug.cgi?id=1122937

The bug is caused by incorrect handling of unaligned data in
arch/arm64/crypto/aes-glue.c. Cryptsetup creates a buffer that is aligned
on 8 bytes, but not on 16 bytes. It opens AF_ALG socket and uses the
socket to encrypt data in the buffer. The arm64 crypto accelerator causes
data corruption or crashes in the scatterwalk_pagedone.

This patch fixes the bug by passing the residue bytes that were not
processed as the last parameter to blkcipher_walk_done.

Linus Torvalds 2062afb4f8 Fix gcc-4.9.0 miscompilation of load_balance() in scheduler
Michel Dänzer and a couple of other people reported inexplicable random
oopses in the scheduler, and the cause turns out to be gcc mis-compiling
the load_balance() function when debugging is enabled.  The gcc bug
apparently goes back to gcc-4.5, but slight optimization changes means
that it now showed up as a problem in 4.9.0 and 4.9.1.

The instruction scheduling problem causes gcc to schedule a spill
operation to before the stack frame has been created, which in turn can
corrupt the spilled value if an interrupt comes in.  There may be other
effects of this bug too, but that's the code generation problem seen in
Michel's case.

This is fixed in current gcc HEAD, but the workaround as suggested by
Markus Trippelsdorf is pretty simple: use -fno-var-tracking-assignments
when compiling the kernel, which disables the gcc code that causes the
problem.  This can result in slightly worse debug information for
variable accesses, but that is infinitely preferable to actual code
generation problems.

Doing this unconditionally (not just for CONFIG_DEBUG_INFO) also allows
non-debug builds to verify that the debug build would be identical: we
can do

    export GCC_COMPARE_DEBUG=1

to make gcc internally verify that the result of the build is
independent of the "-g" flag (it will make the compiler build everything
twice, toggling the debug flag, and compare the results).

Without the "-fno-var-tracking-assignments" option, the build would fail
(even with 4.8.3 that didn't show the actual stack frame bug) with a gcc
compare failure.

Hugh Dickins 8bdd638091 mm: fix direct reclaim writeback regression

  etc.

 970   if (WARN_ON_ONCE((current->flags & (PF_MEMALLOC|PF_KSWAPD)) ==
 971                   PF_MEMALLOC))

I did not respond at the time, because a glance at the PageDirty block
in shrink_page_list() quickly shows that this is impossible: we don't do
writeback on file pages (other than tmpfs) from direct reclaim nowadays.
Dave was hallucinating, but it would have been disrespectful to say so.

However, my own /var/log/messages now shows similar complaints

  WARNING: CPU: 1 PID: 28814 at fs/ext4/inode.c:1881 ext4_writepage+0xa7/0x38b()
  WARNING: CPU: 0 PID: 27347 at fs/ext4/inode.c:1764 ext4_writepage+0xa7/0x38b()

from stressing some mmotm trees during July.

Could a dirty xfs or ext4 file page somehow get marked PageSwapBacked,
so fail shrink_page_list()'s page_is_file_cache() test, and so proceed
to mapping->a_ops->writepage()?

Yes, 3.16-rc1's commit 68711a7463 ("mm, migration: add destination
page freeing callback") has provided such a way to compaction: if
migrating a SwapBacked page fails, its newpage may be put back on the
list for later use with PageSwapBacked still set, and nothing will clear
it.

Whether that can do anything worse than issue WARN_ON_ONCEs, and get
some statistics wrong, is unclear: easier to fix than to think through
the consequences.

Fixing it here, before the put_new_page(), addresses the bug directly,
but is probably the worst place to fix it.  Page migration is doing too
many parts of the job on too many levels: fixing it in
move_to_new_page() to complement its SetPageSwapBacked would be
preferable, except why is it (and newpage->mapping and newpage->index)
done there, rather than down in migrate_page_move_mapping(), once we are
sure of success? Not a cleanup to get into right now, especially not
with memcg cleanups coming in 3.17.

Nicolin Chen a3fdc6749e ASoC: fsl_sai: Improve enable flow in fsl_sai_trigger()
The previous enable flow:
1, Enable TE&RE (SAI starts to consume tx FIFO and feed rx FIFO)
2, Mask IRQ of Tx/Rx to enable its interrupt.
3, Enable DMA request of Tx/Rx.

As this flow would enable DMA request later than TERE, the Tx FIFO
would be easily emptied into underrun while Rx FIFO would be easily
stuffed into overrun due to the delayed DMA transfering.

This issue happened merely occational before the patch 'ASoC: fsl_sai:
Reset FIFOs after disabling TE/RE' because there were useless data
remaining in the FIFO for the gap. However, it manifested after FIFO
reset's implemented.

After this patch, the new flow:
1, Enable DMA request of Tx/Rx.
2, Enable TE&RE (SAI starts to consume tx FIFO and feed rx FIFO)
3, Mask IRQ of Tx/Rx to enable its interrupt.

For trigger start, we don't need to check if it's the first time to
enable TE/RE or second time. It doesn't hurt to enable them any way,
which in the meantime can reduce race condition for TE/RE enabling.

For trigger stop, we will definitely clear FRDE of current direction.
Thus the driver only needs to read the opposite one's.

Kuninori Morimoto d62a3dcd4d ASoC: rsnd: fixup dai remove callback operation
rsnd driver is using SSI/SRC/DVC which are
using "mod" base operation.
These "mod" are supporting "probe" and "remove" callbacks.

Current rsnd_probe should call "remove" if "probe" was failed,
since "probe" might be having DMAEngine handle.
Some mod's "remove" callback might be called without calling
"probe", but it is no problem. because "remove" do nothing
in such case.

So, all mod's "remove" should be called when error case
of rsnd_probe() and rsnd_remove().

pull request: wireless 2014-07-24

Please pull this batch of fixes intended for the 3.16 stream...

For the mac80211 fixes, Johannes says:

"I have two fixes: one for tracing that fixes a long-standing NULL
pointer dereference, and one for a mac80211 issue that causes iwlmvm to
send invalid frames during authentication/association."

and,

"One more fix - for a bug in the newly introduced code that obtains rate
control information for stations."

For the iwlwifi fixes, Emmanuel says:

"It includes a merge damage fix. This region has been changed in -next
and -fixes quite a few times and apparently, I failed to handle it
properly, so here the fix.  Along with that I have a fix from Eliad
to properly handle overlapping BSS in AP mode."

On top of that, Felix provides and ath9k fix for Tx stalls that happen
after an aggregation session failure.

Please let me know if there are problems!  There are some changes
here that will cause merge conflicts in -next.  Once you merge this
I can pull it into wireless-next and resolve those issues.

David S. Miller a88a7be6a2 Merge branch 'mdio_module_unload'
Ezequiel Garcia says:

====================
net: phy: Prevent an MDIO bus from being unloaded while in use

Changes from v1:
  * Dropped the unneeded module_put() on phy_attach_direct().

The motivation of this small series is to fix the current lack of relationship
between an ethernet driver and the MDIO bus behind the PHY device. In such
cases, we would find no visible link between the drivers:

  $ lsmod
  Module                  Size  Used by    Not tainted
  mvmdio                  2941  0
  mvneta                 22069  0

Which means nothing prevents the MDIO driver from being removed:

  $ modprobe -r mvmdio

  # Unable to handle kernel NULL pointer dereference at virtual address 00000060
  pgd = c0004000
  [00000060] *pgd=00000000
  Internal error: Oops: 17 [#1] SMP ARM
  Modules linked in: mvneta [last unloaded: mvmdio]
  CPU: 0 PID: 22 Comm: kworker/0:1 Not tainted 3.16.0-rc5-01127-g62c0816-dirty #608
  Workqueue: events_power_efficient phy_state_machine
  task: df5ec840 ti: df67a000 task.ti: df67a000
  PC is at phy_state_machine+0x1c/0x468
  LR is at phy_state_machine+0x18/0x468
  [snip]

This patchset fixes this problem by adding a pair of module_{get,put},
so the module reference count is increased when the PHY device is attached
and is decreased when the PHY is detached.

Tested with mvneta and mv643xx_eth drivers, which depend on the mvmdio
driver to handle MDIO. This series applies on both net and net-next branches.

This commit adds proper module_{get,put} to prevent the MDIO bus module

a kernel panic produced when a MDIO driver is removed, but the phydev
