rtlwifi: rtl8192cu: Fix kernel deadlock

2015-06-02T11:41:24+00:00

commit 414b7e3b9ce8b0577f613e656fdbc36b34b444dd upstream.

The USB mini-driver in rtlwifi, which is used by rtl8192cu, issues a call to
usb_control_msg() with a timeout value of 0. In some instances where the
interface is shutting down, this infinite wait results in a CPU deadlock. A
one second timeout fixes this problem without affecting any normal operations.

rtlwifi: rtl8192se: Fix regression due to commit 1bf4bbb

2014-06-18T09:17:31+00:00

commit 5f9186990ec4579ee5b7a99b3254c29eda479f36 upstream.

Beginning with kernel 3.13, this driver fails on some systems. The problem
was bisected to:

Commit 1bf4bbb4024dcdab5e57634dd8ae1072d42a53ac
Author: Felix Fietkau 
Title: mac80211: send control port protocol frames to the VO queue

There is noting wrong with the above commit. The regression occurs because
V0 queue on RTL8192SE cards uses priority 6, not the usual 7. The fix is to
modify the rtl8192se routine that sets the correct transmit queue.

rtlwifi: rtl8188ee: initialize packet_beacon

2014-05-15T07:56:09+00:00

commit 328e203fc35f0b4f6df1c4943f74cf553bcc04f8 upstream.

static code analysis from cppcheck reports:

[drivers/net/wireless/rtlwifi/rtl8188ee/trx.c:322]:
  (error) Uninitialized variable: packet_beacon

packet_beacon is not initialized and hence packet_beacon
contains garbage from the stack, so set it to false.
