2015-07-02ath10k: handle 10.4 firmware wmi swba eventRaja Mani3-2/+104
10.4 firmware swba event payload has space to accommodate upto 512 client traffic indication info & one p2p noa descriptor. It's is not matching with exiting swba event format defined for non 10.4 firmware. Non 10.4 firmware swba event format is designed to support only upto only 128 client and four p2p notice of absence descriptor. following changes are done in this patch to enable ath10k to handle 10.4 firmware swba event, - link generic ath10k_wmi_event_host_swba() to handle 10.4 swba event in 10.4 wmi rx handler. - add 10.4 specific swba event structure wmi_10_4_host_swba_event. - new function ath10k_wmi_10_4_op_pull_swba_ev() to parse 10.4 swba event. - increase tim_bitmap[] size in ath10k_vif to 64 to hold 512 station power save state.

2015-07-02ath10k: enhance swba event handler to adapt different size tim bitmapRaja Mani3-15/+66
Due to 512 client support in 10.4 firmware, size of tim ie is going to be slightly higher than non 10.4 firmware. So, size of tim_bitmap what is carried in swba event from 10.4 firmware is bit higher. The only bottle neck to reuse existing swba handler ath10k_wmi_event_host_swba() for 10.4 is that code designed to deal with fixed size tim bitmap(ie, tim_info[].tim_bitmap in wmi_swba_ev_arg). This patch removes such size limitation and makes it more suitable to handle swba event which has different size tim bitmap. All existing swba event parsing functions are changed to adapt this change. Actual support to handle 10.4 swba event is added in next patch. Only preparation is made in this patch.

2015-06-30ath: DFS - limit number of potential PRI sequencesZefir Kurtisi1-1/+1
In the PRI detector, after the current radar pulse has been checked agains existing PRI sequences, it is considered as part of a new potential sequence. Previously, the condition to accept a new sequence was to have at least the same number of pulses as the longest matching sequence. This was wrong, since it led to duplicates of PRI sequences. This patch changes the acceptance criteria for new potential sequences from 'at least' to 'more than' the longest existing. Detection performance remains unaffected, while the number of PRI sequences accounted at runtime (and with it CPU load) is reduced by up to 50%.

When BT is active, we want to avoid the shared antenna for management frame to make sure we don't disturb BT. There was a bug in that code because it chose the antenna BIT(ANT_A) where ANT_A is already a bitmap (0x1). This means that the antenna chosen in the end was ANT_B. While this is not optimal on devices with 2 antennas (it'd disturb BT), it is critical on single antenna devices like 3160 which couldn't connect at all when BT was active.

2015-06-23module: add per-module param_lockDan Streetman1-3/+3
Add a "param_lock" mutex to each module, and update params.c to use the correct built-in or module mutex while locking kernel params. Remove the kparam_block_sysfs_r/w() macros, replace them with direct calls to kernel_param_[un]lock(module). The kernel param code currently uses a single mutex to protect modification of any and all kernel params. While this generally works, there is one specific problem with it; a module callback function cannot safely load another module, i.e. with request_module() or even with indirect calls such as crypto_has_alg(). If the module to be loaded has any of its params configured (e.g. with a /etc/modprobe.d/* config file), then the attempt will result in a deadlock between the first module param callback waiting for modprobe, and modprobe trying to lock the single kernel param mutex to set the new module's param. This fixes that by using per-module mutexes, so that each individual module is protected against concurrent changes in its own kernel params, but is not blocked by changes to other module params. All built-in modules continue to use the built-in mutex, since they will always be loaded at runtime and references (e.g. request_module(), crypto_has_alg()) to them will never cause load-time param changing. This also simplifies the interface used by modules to block sysfs access to their params; while there are currently functions to block and unblock sysfs param access which are split up by read and write and expect a single kernel param to be passed, their actual operation is identical and applies to all params, not just the one passed to them; they simply lock and unlock the global param mutex. They are replaced with direct calls to kernel_param_[un]lock(THIS_MODULE), which locks THIS_MODULE's param_lock, or if the module is built-in, it locks the built-in mutex.

It was possible to force an out of bounds MMIO read/write via debugfs. E.g. on QCA988X this could be triggered with: echo 0x2080e0 | tee /sys/kernel/debug/ieee80211/*/ath10k/reg_addr cat /sys/kernel/debug/ieee80211/*/ath10k/reg_value BUG: unable to handle kernel paging request at ffffc90001e080e0 IP: [<ffffffff8135c860>] ioread32+0x40/0x50 ...

2015-06-16ath10k: enable VHT for IBSSJanusz Dziedzic1-0/+2
Enable VHT support for IBSS, while mac80211/cfg80211 and wpa_supplicant already support this. In my test env, qca988x 2x2 I get: (udp) ath10k-1 >>>> ath10k-2 (server) - speed: 419 Mbits/sec (tcp) ath10k-1 >>>> ath10k-2 (server) - speed: 404 Mbits/sec During tests I used wpa_supplicant (latest git version), which already support IBSS VHT, and choose highest available BW. Also tested with qca6174. Signed-off-by: Janusz Dziedzic <janusz.dziedzic@tieto.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

HTT version itself isn't sufficient to know what HTT version given firmware blob uses. Hence print the recently introduced HTT op version code.

2015-06-16brcmfmac: make brcmf_p2p_detach() call conditionalArend van Spriel1-1/+2
During verification of error handling in brcmf_cfg80211_attach() a null pointer dereference occurred upon calling brcmf_p2p_detach() from brcmf_detach(). This should only be called when the brcmf_cfg80211_attach() has succeeded.

2015-06-16brcmfmac: fix double free of p2pdev interfaceArend van Spriel1-1/+1
When freeing the driver ifp pointer it should also be removed from the driver interface list, which is what brcmf_remove_interface() does. Otherwise, the ifp pointer will be freed twice triggering a kernel oops.
