2015-04-20iwlwifi: pcie: prevent using unmapped memory in fw monitorLiad Kaufman1-5/+6
In the case of a DMA mapping error on the last iteration of the loop of the allocation of memory of the FW monitor we indeed free the pages, but don't NULL out the page variable thus allowing for the possibility of setting the FW monitor variables with invalid data to use.

2015-04-19iwlwifi: mvm: fix Tx Power firmware APIAvri Altman4-15/+58
The firmware doesn't relate the scan to a vif. The scan is run by a separate entity called auxiliary MAC (aka AUX MAC). This AUX MAC needs to get Tx power limitations that are not applied on a specific vif, but on the device as a whole. This can be implemented by using the minimum of all the values set by the user for all the MACs. But then we need to ignore the limitations that come from the AP or regulatory for a specific vif: a specific vif might have regulatory limitations because of the channel is works on. This limit is irrelevant for the AUX MAC. Use the new API from mac80211: the user_power_level in bss_conf to achieve this. Firmware -13.ucode has already moved to this API.

2015-04-17ath10k: use MAC clock rate same as FW uses for survey accuracyPeter Oh1-3/+1
WLAN survey data provides several informative values on each channels such as noise, active time, transmit time, and etc. Regarding the channel activity time data, it is reported from firmware in different form which is number of cycles instead of time itself. Hence host driver converts it to time unit by dividing it by clock rate that is used at baseband MAC. Using difference clock rate from that actual HW is using will result in inaccurate survey data. For instance, channel active time can be reported with bigger than 150ms even though we set Dwell time to 150ms. Therefore set the clock rate to 88000 (88 MHz) which is ath10k baseband MAC is using.

2015-04-17ath10k: enable ibss-rsnJanusz Dziedzic1-0/+2
With latest additions to the driver it seems viable to enable support for IBSS-RSN. It seems to work on QCA988X and 999.999.0.636 but is a bit slow to exchange RSN keys for some reason. This may be a firmware quirk or ath10k is missing something. Nevertheless it makes sense to finally enable IBSS-RSN in ath10k even if somewhat handicapped. QCA6174 firmware doesn't seem to be able to Tx EAPOL frames at all now (they get stuck in hw queues for some reason) so it never gets to set the keys in driver. It's fairly safe to assume that once this is fixed IBSS-RSN will work with QCA6174 firmware without any additional changes. Hence no special handling for advertising IEEE80211_HW_SUPPORTS_PER_STA_GTK and WIPHY_FLAG_IBSS_RSN is done now.

2015-04-17ath10k: fix multiple key static wep with ibssMichal Kazior1-3/+28
Apparently firmware requires both pairwise and groupwise keys to be installed per-peer for static WEP in IBSS. This wasn't necessary for AP mode (and installing both doesn't seem to break AP mode thus there's no special handling). Also there seems to be some kind of issue with mapping tx/rx keys in firmware properly which resulted in wrong keys being used and broken communication between devices. It can be argued the vdev param part is more of a workaround than a real fix. However I couldn't figure out how to fix this differently. It works and isn't super ugly.

2015-04-17ath10k: change static wep key handling for client modeMichal Kazior1-66/+23
mac80211 sets static WEP keys as groupwise while firmware requires them to be installed twice as both pairwise and groupwise. Until now these keys were installed once as pairwise only and, due to that special handling, needed additional tricks to support 802.1x as well. Without this patch in some cases (when AP and ath10k client use different default tx keys) multicast communication was broken.

Frames are logged via tracing in two slices: header and payload, separately. This is done for performance reasons when one wants to, e.g. analyse metadata only of frames only. If for some reason device delivered a frame buffer which was sized below what 802.11 header implied tracing logic would blow doing an invalid memory accesses.

2015-04-15ath: lower JP W53 band DFS detection threshold around 30%Peter Oh1-2/+2
Japan's W53 band requires 50% data traffic during its DFS test, but WLAN baseband used by ath9k and ath10k is not able to achieve current threshold rate, 50%, under the data traffic rate. In other words, HW occasionally fails detecting radar pulses, so that SW cannot get enough radar reports to achieve the rate.

2015-04-15ath: define JP DFS patterns separated from FCCPeter Oh1-11/+18
Separate Japan's DFS pattern from FCC to control PPB threshold. Currently all the radar detectors use the same threshold rate at 50%, but it's not able to achieve if data traffic rate is higher than 40% because WLAN baseband used by ath9k and ath10k often fails detecting radar pulses, so that SW cannot get enough radar reports to achieve the rate. Since Japan's W53 band requires 50% data traffic during its DFS test we need to apply different threshold rate than others on it. Hence define its own pattern to give flexibility to threshold rate.

2015-04-15ath10k: use scan burst for hw rocMichal Kazior3-1/+3
This improves chances of getting onto a foreign channel and thus makes P2P a bit more reliable. Without scan burst it was possible for firmware to not switch to foreign channel resulting in "failed to switch to channel for roc scan" warning. This would also effectively fail some offchan tx requests and lead to P2P find/connect taking longer. This could be observed when other vifs were running/busy, e.g. with P2P GO.

2015-04-15ath: support new FCC DFS Radar Type 1Peter Oh1-5/+14
Add support for new FCC DFS rules released on August 14, 2014. FCC has added a new radar type named Radar Type 1 and original Radar Type 1 is renamed to Radar Type 0 in consequence. During the certificate test, Type 1 PRI values are randomly selected within the range of 518 and 3066 and we divide it to 3 groups based on practical test result data collected for more than a year. For about Radar type ID, it does nothing to functionalities. In other words, even if we re-order the IDs, DFS detection will work as well, but we give the ID with matching to FCC doc. By adding this support, the drivers using this DFS function are able to support both of old and new FCC DFS rules simultaneously without any other changes.

Pull tracing updates from Steven Rostedt: "Some clean ups and small fixes, but the biggest change is the addition of the TRACE_DEFINE_ENUM() macro that can be used by tracepoints. Tracepoints have helper functions for the TP_printk() called __print_symbolic() and __print_flags() that lets a numeric number be displayed as a a human comprehensible text. What is placed in the TP_printk() is also shown in the tracepoint format file such that user space tools like perf and trace-cmd can parse the binary data and express the values too. Unfortunately, the way the TRACE_EVENT() macro works, anything placed in the TP_printk() will be shown pretty much exactly as is. The problem arises when enums are used. That's because unlike macros, enums will not be changed into their values by the C pre-processor. Thus, the enum string is exported to the format file, and this makes it useless for user space tools. The TRACE_DEFINE_ENUM() solves this by converting the enum strings in the TP_printk() format into their number, and that is what is shown to user space. For example, the tracepoint tlb_flush currently has this in its format file: __print_symbolic(REC->reason, { TLB_FLUSH_ON_TASK_SWITCH, "flush on task switch" }, { TLB_REMOTE_SHOOTDOWN, "remote shootdown" }, { TLB_LOCAL_SHOOTDOWN, "local shootdown" }, { TLB_LOCAL_MM_SHOOTDOWN, "local mm shootdown" }) After adding: TRACE_DEFINE_ENUM(TLB_FLUSH_ON_TASK_SWITCH); TRACE_DEFINE_ENUM(TLB_REMOTE_SHOOTDOWN); TRACE_DEFINE_ENUM(TLB_LOCAL_SHOOTDOWN); TRACE_DEFINE_ENUM(TLB_LOCAL_MM_SHOOTDOWN); Its format file will contain this: __print_symbolic(REC->reason, { 0, "flush on task switch" }, { 1, "remote shootdown" }, { 2, "local shootdown" }, { 3, "local mm shootdown" })" * tag 'trace-v4.1' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: (27 commits) tracing: Add enum_map file to show enums that have been mapped writeback: Export enums used by tracepoint to user space v4l: Export enums used by tracepoints to user space SUNRPC: Export enums in tracepoints to user space mm: tracing: Export enums in tracepoints to user space irq/tracing: Export enums in tracepoints to user space f2fs: Export the enums in the tracepoints to userspace net/9p/tracing: Export enums in tracepoints to userspace x86/tlb/trace: Export enums in used by tlb_flush tracepoint tracing/samples: Update the trace-event-sample.h with TRACE_DEFINE_ENUM() tracing: Allow for modules to convert their enums to values tracing: Add TRACE_DEFINE_ENUM() macro to map enums to their values tracing: Update trace-event-sample with TRACE_SYSTEM_VAR documentation tracing: Give system name a pointer brcmsmac: Move each system tracepoints to their own header iwlwifi: Move each system tracepoints to their own header mac80211: Move message tracepoints to their own header tracing: Add TRACE_SYSTEM_VAR to xhci-hcd tracing: Add TRACE_SYSTEM_VAR to kvm-s390 tracing: Add TRACE_SYSTEM_VAR to intel-sst ...

2015-04-07rtlwifi: Add encryption argument in rtl_is_special_data for checking DHCP packet.Taehee Yoo4-6/+11
rtl8192cu can't connect to AP after physical reconnect. according to dmesg, that problem's cause was DHCP timeout. rtl_is_special_data function checks packet type for adjusting rate. when that function is called from _rtl_rc_get_highest_rix, it can not calculate offset correctly. so i add argument is_encn in rtl_is_special_data. is_enc variable mean that iv header is added in skb parameter. i test only rtl8192cu chipset. because i doesn't have other rtlwifi chipsets.

2015-04-02iwlwifi: mvm: capture connection loss as part of MLME triggerEmmanuel Grumbach5-5/+37
The only other way to catch these would have been to monitor the Tx deauth event, but we can send a deauth when we roam. So it would have been tricky to make sure we capture the connection losses only. Define a separate trigger for the connection losses to make it easier to catch them.

2015-04-02iwlwifi: mvm: do string formatting in debug triggersJohannes Berg6-19/+30
The current code has a lot of duplicates of printing into a buffer (while having to make sure it's NUL-filled and -terminated) and then passing that to the debug trigger collection. Since that's error-prone, instead make the debug trigger collection function take a format string and format arguments (with compiler validity checking) and handle the buffer internally. This makes one behavioural change -- instead of sending the whole buffer to userspace (clearing is needed to not leak stack data) it just passes the actual string (including NUL-terminator.)

2015-04-02iwlwifi: mvm: Fix wrongfully flushing frames in the roc/off channel queueMatti Gottlieb1-0/+2
Sending multiple action frames off channel, one after the other can create a race that will result in a timeout: 1. Start sending action frame off channel. 2. Once the frame is sent or the time event is over, the flow will eventually call ieee80211_start_next_roc to start the next roc frame & iwl_mvm_roc_finished schedules to schedule a work to flush the queue. 3. Start sending new roc frame and write it to the queue before the flush work has started. 4. The work is called and it flushes the new packet that was placed on the on the queue so the packet is lost. This causes the frame to be removed & not sent, that causes a timeout in userspace. Flush the work queue that flushes the roc/off channel queue before starting to send a new frame off channel, in order to avoid a race between the new frame that is transmitted off channel & the flushing of the queue.

2015-04-02iwlwifi: mvm: always reconfigure last MCC on initArik Nemtsov2-10/+16
Currently the last found MCC is reconfigured only in the recovery flow. But it should always be used when available, for the ifdown/up or RF-Kill/CT-Kill scenarios. While at it, fix a couple of bugs in the init-from-last-MCC flow. Return an error value when a current MCC is not found. Pass on the regdomain to cfg80211 only if it was changed and don't ignore the return value from the cfg80211-setter function.
