* mwifiex: use maximum ssid length as 0xfe for p2pAniket Nagarnaik2015-07-211-0/+4
| | | | | | | | | | 0xfe is basically a magic number used to ask firmware match provided string in a SSID. In this case, firmware will return scan results containing"DIRECT-" string.

* iwlegacy: convert hex_dump_to_buffer() to %*phAndy Shevchenko2015-07-212-7/+3
| | | | | | | | | | | | | | | | | There is no need to use hex_dump_to_buffer() in the cases like this: hexdump_to_buffer(buf, len, 16, 1, outbuf, outlen, false); /* len <= 16 */ sprintf("%s\n", outbuf); since it maybe easily converted to simple: sprintf("%*ph\n", len, buf); Note: it seems in the case the output is groupped by 2 bytes and looks like a typo. Thus, patch changes that to plain byte stream. Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

* ath9k: export HW random number generatorMiaoqing Pan2015-07-215-0/+110
| | | | | | | | | | | | We measured the FFT-based entropy in 3 ways, Shannon entropy, collision entropy, and directly measured min-entropy. Just to be conservative, we recommend the estimated min-Entropy to be 10 bits per 16-bit value. Analysis was done by Jacobson,David(djacobso@qti.qualcomm.com).

* brcmfmac: set wiphy's addresses to provide valid MACsRafa? Mi?ecki2015-07-212-0/+17
| | | | | | | | | | | | | | | Broadcom's firmware requires every BSS to use MAC address with unique last few bits. The amount of bits may depend on a particular firmware, it was verified to be 2 for BCM43602 one. If this condition won't be fulfilled firmware will reject such MAC: brcmfmac: _brcmf_set_mac_address: Setting cur_etheraddr failed, -52 We don't want to simply set addr_mask as it would also disallow using locally administrated bit. Instead let's build a list of addresses manually enabling 0x2 bit for extra interfaces. Signed-off-by: Rafa? Mi?ecki <zajec5@gmail.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
* ath9k: fix moredata flag endianness in cabq txMichal Kazior2015-07-211-2/+2
| | | | | | | | | | | | | | | | | | | | | | While compiling ath9k with some extra flags I've found that: ath9k/xmit.c +2473 ## 16: warning: restricted __le16 degrades to integer ath9k/xmit.c +2474 ## 36: warning: invalid assignment: &= ath9k/xmit.c +2474 ## 36: left side has type restricted __le16 ath9k/xmit.c +2474 ## 36: right side has type int There's no way for frame ftype/stype to be mistreated as the offending 'moredata' flag when considering cab queue. This could've however theoretically led sometimes to increased power consumption on connected stations as they would keep their Rx active waiting for frames that would never come.

* mwifiex: fix for p2p broken linkAniket Nagarnaik2015-07-213-4/+29
| | | | | | | | | | | | | | | This patch fixes following issues in p2p code paths. 1) bss role, bss type and connection type was not set correctly for p2p GO and p2p client at couple of places. 2) Driver appends a proprietary header to management frames which will be parsed by our firmware. Later while informing TX status to cfg80211, modified frame buffer was passed to cfg80211_mgmt_tx_status() instead of original one.

* ath9k: make DMA stop related messages debug-onlyFelix Fietkau2015-07-214-6/+12
| | | | | | | | | | | | | | | | | | A long time ago, ath9k had issues during reset where the DMA engine would stay active and could potentially corrupt memory. To debug those issues, the driver would print warnings whenever they occur. Nowadays, these issues are gone and the primary cause of these messages is if the MAC is stuck during reset or busy processing a long transmission. This is fairly harmless, yet these messages continue to worry users. To reduce the number of bogus bug reports, turn these messages into debug messages and count their occurence in the "reset" debugfs file.

* mwifiex: usb: Fix double add error when submitting rx urbReyad Attiyat2015-07-211-2/+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: do not increase tx_pkts_queued if receive address tx pausedXinming Hu2015-07-211-1/+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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Whenever any vdev was supposed to be paused all Tx queues were stopped (except offchannel) instead of only these associated with the given vdev. This caused subtle issues with multi-channel/multi-vif scenarios, e.g. authentication of station vif could sometimes fail depending on fw tx pause request timing.

Since AP never has arvif->ps don't even bother checking it. Other combinations may be broken as well so disallow powersave with multivif outright unless firmware advertises otherwise.

| * ath10k: configure frag desc memory to target for qca99X0Raja Mani2015-07-025-2/+96
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Pre qca99X0 chipsets follows the model where dynamically allocate memory for frag desc on getting new skb for TX. But, this is not going to be the case in qca99X0. It expects frag desc memory to be allocated at boot time and let the driver to reuse allocated memory after every TX completion. So there won't be any dynamic frag memory memory allocation in qca99X0 during data transmission. qca99X0 hardware doesn't need fragment desc address to be programmed in msdu descriptor for every data transaction. It needs to know only starting address of fragment descriptor at the time of the boot. During data transmission, qca99X0 hardware can retrieve corresponding frag addr by adding programmed frag desc base addr + msdu id. Allocate continuous fragment descriptor memory (same size as number of descriptor) at the time of target initialization and configure allocated dma address to the target via HTT_H2T_MSG_TYPE_FRAG_DESC_BANK_CFG. How this is allocated continuous memory is going to be used is not covered in this patch. It just allocates memory and hand over to firmware. If we don't do it at init time, qca99X0 will stall when firmware tries to do TX. Signed-off-by: Raja Mani <rmani@qti.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
