mac80211: pass block ack session timeout to to driver

2016-01-14T10:13:17+00:00

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.

rsi: bool tests do not need comparison

2015-12-30T15:34:26+00:00

This is an API consolidation only. Bool initializations should
use true and false thus bool tests don't need an explicit comparison.

rsi: consolidate kmalloc/memset 0 calls to kzalloc

2015-12-30T15:32:30+00:00

This is an API consolidation only. The use of kmalloc + memset to 0
is equivalent to kzalloc.

mac80211: allow to transmit A-MSDU within A-MPDU

2015-09-22T13:21:23+00:00

Advertise the capability to send A-MSDU within A-MPDU
in the AddBA request sent by mac80211. Let the driver
know about the peer's capabilities.

rsi: Fix possible leak when loading firmware

2015-08-25T12:37:41+00:00

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.

rsi: Fix failure to load firmware after memory leak fix and fix the leak

2015-07-31T06:22:44+00:00

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.

mac80211: convert HW flags to unsigned long bitmap

2015-06-10T14:05:36+00:00

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.

rsi: fix memory leak in rsi_load_ta_instructions()

2014-12-24T15:26:08+00:00

Memory allocated by kmemdup() in rsi_load_ta_instructions() is leaked.
But duplication of firmware data here is useless,
so the patch removes kmemdup() at all.

rsi: fix memory leaks and error handling in rsi_91x_usb

2014-07-01T18:26:26+00:00

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.
