2014-07-01rtl818x_pci: Fix BSSID register written incorrectlyAndrea Merello1-3/+4
BSSID register was written with six byte-writes. It seems that, similarly to what happens with MAC registers, they needs to be written with one 16-bit and one 32-bit writes, otherwise the write does not work. The byte write didn't work only on my rtl8185, while it worked on rtl8180 and rtl8187se, BTW since there are probably a number of different ASIC revisions out of there, I let the change to affect all cards. It shouldn't hurt anyway. Signed-off-by: Andrea Merello <[email protected]> Signed-off-by: John W. Linville <[email protected]>

2014-07-01rsi: fix memory leaks and error handling in rsi_91x_usbAlexey Khoroshilov1-20/+38
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).

Earlier the listen interval is used to decide switching between operating and off-channels during bgscan and to improve throughput, the listen interval is reduced to 1. After optimiztion in scan state machine, listen period is not used for decision making and hence reverting it back to original value.

2014-06-25net/wireless/brcm80211/brcmfmac: Make return type and name reflect actual ↵Rasmus Villemoes3-6/+5
semantics Applying ++ to a bool is equivalent to setting it true, regardless of its initial value (bools are not uint1_t). Hence the function wl_get_vif_state_all can only ever return true/false. The only in-tree caller uses its return value as a boolean. So update its return type, and since the list traversal and bit testing have no side effects, just return true immediately. Its return value tells if any vif is in the specified state, so also rename it to brcmf_get_vif_state_any.

https://bugzilla.kernel.org/show_bug.cgi?id=70191 https://bugzilla.kernel.org/show_bug.cgi?id=77581 It is observed that sometimes Tx packet is downloaded without adding driver's txpd header. This results in firmware parsing garbage data as packet length. Sometimes firmware is unable to read the packet if length comes out as invalid. This stops further traffic and timeout occurs. The root cause is uninitialized fields in tx_info(skb->cb) of packet used to get garbage values. In this case if MWIFIEX_BUF_FLAG_REQUEUED_PKT flag is mistakenly set, txpd header was skipped. This patch makes sure that tx_info is correctly initialized to fix the problem.
