2013-03-18ath6kl: convert ath6kl_info/err/warn macros to real functionsKalle Valo2-7/+54
After this it's cleaner to add trace calls. Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2013-03-18ath6kl: adding tracing points for htc_mboxKalle Valo2-1/+76
Add tracing points for htc layer, just dumping the packets to user space. I wasn't really sure what to do with the status value, it might not always be accurate, but I included it anyway. I skipped htc_pipe (and usb) implementation for now. Need to add those tracepoints later. Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2013-03-18ath6kl: add tracing point for hif irqsKalle Valo2-0/+23
Add a tracing point for hif irq and dump the register content to user space. This is in hif.c as we could use the same code also with SPI but, as ath6kl doesn't SPI and most likely never will be, this is used just by SDIO so name the trace point as ath6kl_sdio_irq to make it easier to manage filters.

2013-03-18ath6kl: cold reset target after host warm bootKalle Valo2-2/+13
Julien reported that ar6004 usb device fails to initialise after host has been rebooted and power is still on for the ar6004 device. He found out that doing a cold reset fixes the issue. I wasn't sure what would be the best way to detect if target needs a reset so I settled on checking a timeout from htc_wait_recv_ctrl_message().

2013-02-19rtlwifi: usb: allocate URB control message setup_packet and data buffer ↵Jussi Kivilinna1-16/+28
separately rtlwifi allocates both setup_packet and data buffer of control message urb, using shared kmalloc in _usbctrl_vendorreq_async_write. Structure used for allocating is: struct { u8 data[254]; struct usb_ctrlrequest dr; }; Because 'struct usb_ctrlrequest' is __packed, setup packet is unaligned and DMA mapping of both 'data' and 'dr' confuses ARM/sunxi, leading to memory corruptions and freezes. Patch changes setup packet to be allocated separately.

Fix this issue by making the TE removal synchronous as well, this means that we wait for the response to that command first, before there's any chance of sending a new one. Also, to detect such issues more easily in the future, add a warning to the notification handler that detects them.

Larry noticed (and bisected) that commit df881293c6ba9a12868491a717b25 "cfg80211: Pass TDLS peer's QoS/HT/VHT information during set_station" broke secure connections. This is is the case only for drivers that don't support TDLS, where any kind of change, even just the change of authorized flag that is required for normal operation, was rejected now. To fix this, remove the checks. I have some patches that will add proper verification for all the different cases later.
