rtlwifi: Align private space in rtl_priv struct

2013-10-13T21:51:08+00:00

commit 60ce314d1750fef843e9db70050e09e49f838b69 upstream.

The private array at the end of the rtl_priv struct is not aligned.
On ARM architecture, this causes an alignment trap and is fixed by aligning
that array with __align(sizeof(void *)). That should properly align that
space according to the requirements of all architectures.

rt2800: fix wrong TX power compensation

2013-10-01T15:55:47+00:00

commit 6e956da2027c767859128b9bfef085cf2a8e233b upstream.

We should not do temperature compensation on devices without
EXTERNAL_TX_ALC bit set (called DynamicTxAgcControl on vendor driver).
Such devices can have totally bogus TSSI parameters on the EEPROM,
but still threaded by us as valid and result doing wrong TX power
calculations.

This fix inability to connect to AP on slightly longer distance on
some Ralink chips/devices.

ath9k: always clear ps filter bit on new assoc

2013-09-26T23:52:47+00:00

commit 026d5b07c03458f9c0ccd19c3850564a5409c325 upstream.

Otherwise in some cases, EAPOL frames might be filtered during the
initial handshake, causing delays and assoc failures.

ath9k_htc: Restore skb headroom when returning skb to mac80211

2013-09-08T04:49:32+00:00

commit d2e9fc141e2aa21f4b35ee27072d84e9aa6e2ba0 upstream.

ath9k_htc adds padding between the 802.11 header and the payload during
TX by moving the header. When handing the frame back to mac80211 for TX
status handling the header is not moved back into its original position.
This can result in a too small skb headroom when entering ath9k_htc
again (due to a soft retransmission for example) causing an
skb_under_panic oops.

Fix this by moving the 802.11 header back into its original position
before returning the frame to mac80211 as other drivers like rt2x00
or ath5k do.

Hostap: copying wrong data prism2_ioctl_giwaplist()

commit 909bd5926d474e275599094acad986af79671ac9 upstream.

We want the data stored in "addr" and "qual", but the extra ampersands
mean we are copying stack data instead.

zd1201: do not use stack as URB transfer_buffer

commit 1206ff4ff9d2ef7468a355328bc58ac6ebf5be44 upstream.

Patch fixes zd1201 not to use stack as URB transfer_buffer. URB buffers need
to be DMA-able, which stack is not.

Patch is only compile tested.

rt2x00: fix stop queue

2013-08-11T22:38:22+00:00

commit e2288b66fe7ff0288382b2af671b4da558b44472 upstream.

Since we clear QUEUE_STARTED in rt2x00queue_stop_queue(), following
call to rt2x00queue_pause_queue() reduce to noop, i.e we do not
stop queue in mac80211.

To fix that introduce rt2x00queue_pause_queue_nocheck() function,
which will stop queue in mac80211 directly.

Note that rt2x00_start_queue() explicitly set QUEUE_PAUSED bit.

Note also that reordering operations i.e. first call to
rt2x00queue_pause_queue() and then clear QUEUE_STARTED bit, will race
with rt2x00queue_unpause_queue(), so calling ieee80211_stop_queue()
directly is the only available solution to fix the problem without
major rework.
