This reverts commit 6301566e. Oleksij Rempel noticed that the randomness doesn't look to be good enough and Stephan Mueller commented: "I would say that the discussed RNG does not seem fit for hooking it up with the hwrandom framework." http://lkml.kernel.org/g/3945775.m5HblJPgiO@tauon.atsec.com So let's the revert the patch until we are sure that we can trust this random generator.

Currently of_default_bus_match_table is not exported so we can only use this feature when bcma is build into the kernel.

While changing interface type from p2p client or p2p go to station, we should update counters for p2p interface and station interface. Also calling mwifiex_cfg80211_deinit_p2p method instead of mwifiex_cfg80211_init_p2p_client method to deinit p2p interface. Signed-off-by:

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:

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). Signed-off-by:

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:

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. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

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.

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. Signed-off-by:

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. Signed-off-by:
