The diffstat looks scary as we created a new directory realtek for all realtek drivers. In the future I'm planning to create similar directories for all vendors, currently we just have ath, mediatek and realtek. This change has been in linux-next for a couple of weeks so it should be safe, but of course you never know. There's also a new driver rtl8xxxu for few realtek USB devices. This just made it to the last linux-next build. Otherwise there's nothing really special, more info below. If time permits, and it's ok for you, I'm hoping to send you a one more pull request this week. brcmfmac * using netdev carrier state * add and rework some cfg80211 callbacks mainly for AP mode * use devcoredump when triggered by firmware event realtek * create new directory drivers/net/wireless/realtek/ for all realtek drivers, not visible to users (no kconfig changes etc) * add rtl8xxxu, a new mac80211 driver for RTL8723AU, RTL8188CU, RTL8188RU, RTL8191CU, RTL8192CU and hopefully more in the future ath10k * add board 2 API support for automatically choosing correct board file * data path optimisations * disable PCI power save for qca988x and QCA99x0 due to interop reasons wil6210 * BlockAckReq support * firmware crashdump using devcoredump * capture all frames with sniffer ==================== Signed-off-by: David S.

* / cfg80211: Add multiple scan plans for scheduled scanAvraham Stern2015-10-131-1/+1
|/ | | | | | | | | | | | | | | | | | | | | | | Add the option to configure multiple 'scan plans' for scheduled scan. Each 'scan plan' defines the number of scan cycles and the interval between scans. The scan plans are executed in the order they were configured. The last scan plan will always run infinitely and thus defines only the interval between scans. The maximum number of scan plans supported by the device and the maximum number of iterations in a single scan plan are advertised to userspace so it can configure the scan plans appropriately. When scheduled scan results are received there is no way to know which scan plan is being currently executed, so there is no way to know when the next scan iteration will start. This is not a problem, however. The scan start timestamp is only used for flushing old scan results, and there is no difference between flushing all results received until the end of the previous iteration or the start of the current one, since no results will be received in between.

From Thomas Graf, Jiri Benc, and a cast of others. 10) Add Identifier Locator Addressing support for ipv6, from Tom Herbert. 11) Support fragmented SKBs in iwlwifi, from Johannes Berg. 12) Allow perf PMUs to be accessed from eBPF programs, from Kaixu Xia. 13) Add BQL support to 3c59x driver, from Loganaden Velvindron. 14) Stop using a zero TX queue length to mean that a device shouldn't have a qdisc attached, use an explicit flag instead. From Phil Sutter. 15) Use generic geneve netdevice infrastructure in openvswitch, from Pravin B Shelar. 16) Add infrastructure to avoid re-forwarding a packet in software that was already forwarded by a hardware switch.

* | cfg80211: properly send NL80211_ATTR_DISCONNECTED_BY_AP in disconnectJohannes Berg2015-05-261-2/+2
|/ | | | | | | | | | | | | | | | | | | | When we disconnect from the AP, drivers call cfg80211_disconnect(). This doesn't know whether the disconnection was initiated locally or by the AP though, which can cause problems with the supplicant, for example with WPS. This issue obviously doesn't show up with any mac80211 based driver since mac80211 doesn't call this function. Fix this by requiring drivers to indicate whether the disconnect is locally generated or not. I've tried to update the drivers, but may not have gotten the values correct, and some drivers may currently not be able to report correct values. In case of doubt I left it at false, which is the current behaviour. For libertas, make adjustments as indicated by Dan Williams.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This will expose in /sys whether the ifname of a device is set by userspace or generated by the kernel. The latter kind (wlanX, etc) is not deterministic, so userspace needs to rename these devices to names that are guaranteed to stay the same between reboots. The former, however should never be renamed, so userspace needs to be able to reliably tell the difference.

| * cfg80211: add bss_type and privacy arguments in cfg80211_get_bss()Dedy Lansky2015-03-031-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 802.11ad adds new a network type (PBSS) and changes the capability field interpretation for the DMG (60G) band. The same 2 bits that were interpreted as "ESS" and "IBSS" before are re-used as a 2-bit field with 3 valid values (and 1 reserved). Valid values are: "IBSS", "PBSS" (new) and "AP". In order to get the BSS struct for the new PBSS networks, change the cfg80211_get_bss() function to take a new enum ieee80211_bss_type argument with the valid network types, as "capa_mask" and "capa_val" no longer work correctly (the search must be band-aware now.) The remaining bits in "capa_mask" and "capa_val" are used only for privacy matching so replace those two with a privacy enum as well.

* cfg80211: change bandwidth reporting to explicit fieldJohannes Berg2015-01-151-1/+2
| | | | | | | | | | | | | | | | | | For some reason, we made the bandwidth separate flags, which is rather confusing - a single rate cannot have different bandwidths at the same time. Change this to no longer be flags but use a separate field for the bandwidth ('bw') instead. While at it, add support for 5 and 10 MHz rates - these are reported as regular legacy rates with their real bitrate, but tagged as 5/10 now to make it easier to distinguish them. In the nl80211 API, the flags are preserved, but the code now can also clearly only set a single one of the flags. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
* cfg80211: remove enum station_info_flagsJohannes Berg2015-01-082-8/+7
| | | | | | | | | | | | | | This is really just duplicating the list of information that's already available in the nl80211 attribute, so remove the list. Two small changes are needed: * remove STATION_INFO_ASSOC_REQ_IES complete, but the length (assoc_req_ies_len) can be used instead * add NL80211_STA_INFO_RX_DROP_MISC which exists internally but not in nl80211 yet This gets rid of the duplicate maintenance of the two lists.

These are mostly fixes to what we've sent to you before for next merge window." For the iwlwifi bits, Emmanuel says: "I have the usual amount of BT Coex stuff. Arik continues to work on TDLS and Ariej contributes a few things for HS2.0. I added a few more things to the firmware debugging infrastructure. Eran fixes a small bug - pretty normal content." And for the Atheros bits, Kalle says: "For ath6kl me and Jessica added support for ar6004 hw3.0, our latest version of ar6004. For ath10k Janusz added a printout so that it's easier to check what ath10k kconfig options are enabled. He also added a debugfs file to configure maximum amsdu and ampdu values. Also we had few fixes as usual." On top of that is the usual large batch of various driver updates -- brcmfmac, mwifiex, the TI drivers, and wil6210 all get some action. Rafał has also been very busy with b43 and related updates. Also, I pulled the wireless tree into this in order to resolve a merge conflict... P.S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The functionality defined through these flags were actually firmware features which can change between firmware versions. To make it possible to support different firmware versions with the same driver, convert the flags to firmware feature flags. For backwards compatibility support for old ar6004 firmware FW API 3 or smaller images we forcefully set the feature bits in the driver. Starting from FW API 5 the firmware image needs to set them.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This also propagates through the drivers. The orinoco driver uses the cfg80211 API structs for internal bookkeeping, and so needs a (void *) cast that removes the const - but that's OK because it allocates those pointers.

not syncing: Fatal exception Jason's analysis: "The GCC 4.8.1 compiler will not do the for-loop till scat_entries, instead, it only run one round loop. This may be caused by that the GCC 4.8.1 thought that the scat_list only have one item and then no need to do full iteration, but this is simply wrong by looking at the assebly code. This will cause the sg buffer not get set when scat_entries > 1 and thus lead to kernel panic. Note: This issue not observed with GCC 4.7.2, only found on the GCC 4.8.1)" Fix this by using the normal [0] style for defining unknown number of list entries following the struct. This also fixes corruption with scat_q_depth, which was mistankely added to the end of struct and overwritten if there were more than item in the scat list.
