Johannes Berg 266af4c745 iwlagn: support off-channel TX
Add support to iwlagn for off-channel TX. The
microcode API for this is a bit strange in that
it uses a hacked-up scan command, so the scan
code needs to change quite a bit to accomodate
that and be able to send it out.

Jason Young 808118cb41 mac80211: do not enable ps if 802.1x controlled port is unblocked
If dynamic_ps is disabled, enabling power save before the 4-way
handshake completes may delay the station from being authorized to
send/receive traffic, i.e. increase roaming times. It also may result in
a failed 4-way handshake depending on the AP's timing requirements and
beacon interval, and the station's listen interval.

To fix this, prevent power save from being enabled while the station
isn't authorized and recalculate power save whenever the station's
authorized state changes.

Dan Carpenter d89dba7a27 libertas: fix write past end of array in mesh_id_get()
defs.meshie.val.mesh_id is 32 chars long.  It's not supposed to be NUL
terminated.  This code puts a terminator on the end to make it easier to
print to sysfs.  The problem is that if the mesh_id fills the entire
buffer the original code puts the terminator one spot past the end.

The way the original code was written, there was a check to make sure
that maxlen was less than PAGE_SIZE.  Since we know that maxlen is at
most 34 chars, I just removed the check.

Felix Fietkau 2e286947f1 ath9k: remove support for the FIF_PROMISC_IN_BSS filter flag
The hardware rx filter flag triggered by FIF_PROMISC_IN_BSS is overly broad
and covers even frames with PHY errors. When this flag is enabled, this message
shows up frequently during scanning or hardware resets:

ath: Could not stop RX, we could be confusing the DMA engine when we start RX up

Since promiscuous mode is usually not particularly useful, yet enabled by
default by bridging (either used normally in 4-addr mode, or with hacks
for various virtualization software), we should sacrifice it for better
reliability during normal operation.

This patch leaves it enabled if there are active monitor mode interfaces, since
it's very useful for debugging.

Grazvydas Ignotas 5f6722ee63 wl1251: fix elp_work race condition
While working on PS I've noticed elp_work is kicking rather often, and
sometimes the chip is put to sleep before 5ms delay expires. This
seems to happen because by the time wl1251_ps_elp_wakeup is called
elp_work might still be pending. After wakeup is done, the processing
may take some time, during which 5ms might expire and elp_work might
get scheduled. In this case, ss soon as 1st thread finishes work and
releases the mutex, elp_work will then put the device to sleep without
5ms delay. In addition 1st thread will queue additional elp_work
needlessly.

Fix this by cancelling work in wl1251_ps_elp_wakeup instead.

Grazvydas Ignotas d0c331aff9 wl1251: remove wl1251_ps_set_elp function
wl1251_ps_set_elp() only does acx_sleep_auth call and takes the chip
from/to ELP, however all callers of wl1251_ps_set_mode() have already
taken the chip out of ELP and puts it back to ELP when they finish.
This makes ELP calls (and register writes they result in) superfluous.

So remove wl1251_ps_set_elp function and call acx_sleep_auth directly.

J. Bruce Fields d891eedbc3 fs/dcache: allow d_obtain_alias() to return unhashed dentries
Without this patch, inodes are not promptly freed on last close of an
unlinked file by an nfs client:

	client$ mount -tnfs4 server:/export/ /mnt/
	client$ tail -f /mnt/FOO
	...
	server$ df -i /export
	server$ rm /export/FOO
	(^C the tail -f)
	server$ df -i /export
	server$ echo 2 >/proc/sys/vm/drop_caches
	server$ df -i /export

the df's will show that the inode is not freed on the filesystem until
the last step, when it could have been freed after killing the client's
tail -f. On-disk data won't be deallocated either, leading to possible
spurious ENOSPC.

This occurs because when the client does the close, it arrives in a
compound with a putfh and a close, processed like:

	- putfh: look up the filehandle.  The only alias found for the
	  inode will be DCACHE_UNHASHED alias referenced by the filp
	  this, so it creates a new DCACHE_DISCONECTED dentry and
	  returns that instead.
	- close: closes the existing filp, which is destroyed
	  immediately by dput() since it's DCACHE_UNHASHED.
	- end of the compound: release the reference
	  to the current filehandle, and dput() the new
	  DCACHE_DISCONECTED dentry, which gets put on the
	  unused list instead of being destroyed immediately.

Nick Piggin suggested fixing this by allowing d_obtain_alias to return
the unhashed dentry that is referenced by the filp, instead of making it
create a new dentry.

Leave __d_find_alias() alone to avoid changing behavior of other
callers.

Also nfsd doesn't need all the checks of __d_find_alias(); any dentry,
hashed or unhashed, disconnected or not, should work.

The tg3 NVRAM selftest actually fails when validating the checksum of
the legacy NVRAM format.  However, the test still reported success
because the last update of the return code was a success from the NVRAM
reads.  This patch fixes the code so that the error return code defaults
to a failure status.  Then the patch fixes the reason why the checsum
validation failed.

"tg3: Expand 5719 workaround" extended a 5719 A0 workaround to all
revisions of the chip.  There was a change that should have been a
part of that patch that was missed.  This patch adds the missing
piece.

Marco Stornelli 1ca551c6ca Check for immutable/append flag in fallocate path
In the fallocate path the kernel doesn't check for the immutable/append
flag. It's possible to have a race condition in this scenario: an
application open a file in read/write and it does something, meanwhile
root set the immutable flag on the file, the application at that point
can call fallocate with success. In addition, we don't allow to do any
unreserve operation on an append only file but only the reserve one.
