2014-03-31rtl8187: fix use after free on failure path in rtl8187_probe()Alexey Khoroshilov
If allocation of io_dmabuf fails, rtl8187_probe() calls usb_put_dev(udev) while usb_get_dev(udev) is not called yet. As a result refcnt is decremented incorrectly and usb_dev can be used after memory deallocation. Found by Linux Driver Verification project (linuxtesting.org).

2014-03-31rtl8180: don't use weird trick to access "far" registersAndrea Merello
In rtl8180/rtl8185/rtl8187se the register space is represented using packed structure type. Register are thus accessed using a pointer of this type. All registers are packed toghether, and only small gaps are present. However Rtl8187se has also some "sparse" registers, very far from the "main register block". It could be possible to access them by simply declare huge reserved blocks inside the register struct (and this causes NO memory waste). However, for various reasons, access to those "far" registers is done with special dedicated macros, without declaring them in the register struct. This is done in an intricate manner, that makes code less readable and caused static analisys tool to produce warnings. This patch keeps the "macro" mechanism, but it changes its implementation in a simplier and more straightforward way. Signed-off-by: Andrea Merello <andrea.merello@gmail.com> Signed-off-by: John W.

2014-03-31rtl8187: fix compile warningAndrea Merello
ANAPARAM3 register, defined in the rtl818x common register struct, is accessed as 16bit by rtl8187se and as 8bit by rtl8187b. Since I have no documentation about this, I can only stick to the reference code and to what is known to work. This issue has been addressed by a patch from Larry Finger that introduces an "union", in the register struct. In my last patch-set I applied it on the register struct, but I forget to update rtl8187 driver too. This patch does it.

2014-03-27rtl8180: rationalize TX queuesAndrea Merello
On currently supported HW there are four TX queues (three for normal packets and one for beacons). The driver uses just one TX queue, and declare to mac80211 to support just one queue, but it allocates coherent memory for all queues. Furthermore the TX is code is written assumimg four queues exists, and even if we decide to enable more queues in future, its mapping rule to mac80211 is fixed. This means we have memory waste on rtl8180/rtl8185, and we have also not enough flexibility to add support for boards (rtl8187se) that will use more queues. This patch changes things in order to allocate coherent memory only for the queues effectively used and it make it possible to specify how to map hardware queues on mac80211 queues, that will be used by rtl8187se code as soon it will be merged. Note: even if the beacon queue is currently unused, this should change, so I kept it. Signed-off-by: Andrea Merello <andrea.merello@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
