2015-07-21mwifiex: usb: Fix double add error when submitting rx urbReyad Attiyat1-2/+4
There is an error that can occur where the driver adds the same URB to USB submission list twice. This happens since mwifiex_usb_submit_rem_rx can submit packets at same time as an rx urb complete callback. This causes list corruption and is fixed by not setting the skb to NULL when submitting an rx packet.

mwifiex_set_wowlan_mef_entry attempts to free a passed-in pointer in case of an error. The only caller (mwifiex_set_mef_filter) passes that pointer as an offset into allocated memory, so any attempt to free that will not be the actual allocated pointer. Address this by changing mwifiex_set_wowlan_mef_entry to not do any free, and to cause mwifiex_set_mef_filter to do the appropriate free if the call to mwifiex_set_wowlan_mef_entry fails.

2015-07-21mwifiex: update domain_info upon band change in start_apAvinash Patil3-2/+9
It was observed that AP beacons would not reflect correct regulatory information upon starting AP in A band. This was because of missing AP config band update in set_channel of start_ap. Also we configure 11D settings info FW only for specific band. So we need to download domain info to FW even if domain remains unchanged but band is changed.

2015-07-21mwifiex: do not increase tx_pkts_queued if receive address tx pausedXinming Hu1-1/+4
If tx_pkts_queued is increased for tx paused receive address, tx process will be triggered for this packet. But since RA list was tx paused, there will be an infinite loop in mwifiex_wmm_process_tx waiting for the event(tx pause, tdls cs) to cancel tx pause. This will be an dead loop, since main_process was locked at this time, there will be no opportunity to process event. So do not increase tx_pkts_queued if receive address tx paused, this will be restored RA list is unpaused.

2015-06-02mwifiex: device dump support via devcoredump frameworkAmitkumar Karwar6-117/+103
Currently device dump generated in the driver is retrieved using ethtool set/get dump commands. We will get rid of ethtool approach and use devcoredump framework. Device dump can be trigger by cat /debugfs/mwifiex/mlanX/device_dump and when the dump operation is completed, data can be read by cat /sys/class/devcoredump/devcdX/data We have prepared following script to split device dump data into multiple files. [root]# cat mwifiex_split_dump_data.sh #!/bin/bash # usage: ./mwifiex_split_dump_data.sh dump_data fw_dump_data=$1 mem_type="driverinfo ITCM DTCM SQRAM APU CIU ICU MAC" for name in ${mem_type[@]} do sed -n "/Start dump $name/,/End dump/p" $fw_dump_data > tmp.$name.log if [ ! -s tmp.$name.log ] then rm -rf tmp.$name.log else #Remove the describle info "Start dump" and "End dump" sed '1d' tmp.$name.log | sed '$d' > /data/$name.log if [ -s /data/$name.log ] then echo "generate /data/$name.log" else sed '1d' tmp.$name.log | sed '$d' > /var/$name.log echo "generate /var/$name.log" fi rm -rf tmp.$name.log fi done Signed-off-by: Amitkumar Karwar <akarwar@marvell.com> Signed-off-by: Cathy Luo <cluo@marvell.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2015-06-02mwifiex: use generic name 'device dump'Amitkumar Karwar8-44/+52
Currently we are dumping driver information also inside firmware dump API. We will call it as device dump and dump driver and firmware data separately. Signed-off-by: Amitkumar Karwar <akarwar@marvell.com> Signed-off-by: Cathy Luo <cluo@marvell.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

2015-06-02mwifiex: dump driver information for PCIe interfaceAmitkumar Karwar1-0/+2
Currently we are dumping driver information only for SDIO interface. This patch adds missing mwifiex_dump_drv_info() call for PCIe interface. Signed-off-by: Amitkumar Karwar <akarwar@marvell.com> Signed-off-by: Cathy Luo <cluo@marvell.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

As drv_info_dump pointer doesn't get reset, we may end up freeing the allocated memory twice. Signed-off-by: Amitkumar Karwar <akarwar@marvell.com> Signed-off-by: Cathy Luo <cluo@marvell.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2015-06-02mwifiex: fix SDIO firmware dump problemAmitkumar Karwar1-0/+7
It's been observed that firmware doesn't go back to normal state when all firmware memories are dumped. As a result, further commands are blocked. This happens due to missing driver change of writing READ DONE to control register for SDIO interface. This patch adds a missing change to fix the problem.
