2016-01-14mac80211: pass block ack session timeout to to driverSara Sharon
Currently mac80211 does not inform the driver of the session block ack timeout when starting a rx aggregation session. Drivers that manage the reorder buffer need to know this parameter. Seeing that there are now too many arguments for the drv_ampdu_action() function, wrap them inside a structure.

2015-08-25rsi: Fix possible leak when loading firmwareChristian Engelmayer
Commit 5d5cd85ff441 ("rsi: Fix failure to load firmware after memory leak fix and fix the leak") also added a check on the allocation of DMA-accessible memory that may directly return. In that case the already allocated firmware data is leaked. Make sure the data is always freed correctly. Detected by Coverity CID 1316519.

2015-07-31rsi: Fix failure to load firmware after memory leak fix and fix the leakMike Looijmans
Fixes commit eae79b4f3e82 ("rsi: fix memory leak in rsi_load_ta_instructions()") which stopped the driver from functioning. Firmware data has been allocated using vmalloc(), resulting in memory that cannot be used for DMA. Hence the firmware was first copied to a buffer allocated with kmalloc() in the original code. This patch reverts the commit and only calls "kfree()" to release the buffer after sending the data. This fixes the memory leak without breaking the driver. Add a comment to the kmemdup() calls to explain why this is done, and abort if memory allocation fails. Tested on a Topic Miami-Florida board which contains the rsi SDIO chip. Also added the same kfree() call to the USB glue driver. This was not tested on actual hardware though, as I only have the SDIO version.

2015-06-10mac80211: convert HW flags to unsigned long bitmapJohannes Berg
As we're running out of hardware capability flags pretty quickly, convert them to use the regular test_bit() style unsigned long bitmaps. This introduces a number of helper functions/macros to set and to test the bits, along with new debugfs code. The occurrences of an explicit __clear_bit() are intentional, the drivers were never supposed to change their supported bits on the fly. We should investigate changing this to be a per-frame flag.

2014-12-24rsi: fix memory leak in rsi_load_ta_instructions()Alexey Khoroshilov

2014-07-01rsi: fix memory leaks and error handling in rsi_91x_usbAlexey Khoroshilov
The patch fixes a couple of issues: - absence of deallocation of rsi_dev->rx_usb_urb[0] in the driver; - potential NULL pointer dereference because of lack of checks for memory allocation success in rsi_init_usb_interface(). By the way, it makes rsi_probe() returning error code instead of 1 and fixes comments regarding returning values. Found by Linux Driver Verification project (linuxtesting.org).
