| * cfg80211: Enhance the AKM advertizement to support per interfaceSrikanth Marepalli2020-10-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit ab4dfa20534e ("cfg80211: Allow drivers to advertise supported AKM suites") introduces the support to advertize supported AKMs to userspace. This needs an enhancement to advertize the AKM support per interface type, specifically for the cfg80211-based drivers that implement SME and use different mechanisms to support the AKM's for each interface type (e.g., the support for SAE, OWE AKM's take different paths for such drivers on STA/AP mode). This commit aims the same and enhances the earlier mechanism of advertizing the AKMs per wiphy. Add new nl80211 attributes and data structure to provide supported AKMs per interface type to userspace. The AKMs advertized in akm_suites are default capabilities if not advertized for a specific interface type in iftype_akm_suites.

* | BACKPORT: cfg80211: remove enum ieee80211_bandJohannes Berg2020-02-02
|/ | | | | | | | | | | | | | This enum is already perfectly aliased to enum nl80211_band, and the only reason for it is that we get IEEE80211_NUM_BANDS out of it. There's no really good reason to not declare the number of bands in nl80211 though, so do that and remove the cfg80211 one.

* cfg80211/nl80211: Offload OWE processing to user space in AP modeSunil Dutt2019-04-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This interface allows the host driver to offload OWE processing to user space. This intends to support OWE (Opportunistic Wireless Encryption) AKM by the drivers that implement SME but rely on the user space for the cryptographic/OWE processing in AP mode. Such drivers are not capable of processing/deriving the DH IE. A new NL80211 command - NL80211_CMD_UPDATE_OWE_INFO is introduced to send the request/event between the host driver and user space. Driver shall provide the OWE info (MAC address and DH IE) of the peer to user space for cryptographic processing of the DH IE through the event. Accordingly, the user space shall update the OWE info/DH IE to the driver. Following is the sequence in AP mode for OWE authentication. Driver passes the OWE info obtained from the peer in the Association Request to the user space through the event cfg80211_update_owe_info_event. User space shall process the OWE info received and generate new OWE info. This OWE info is passed to the driver through NL80211_CMD_UPDATE_OWE_INFO request. Driver eventually uses this OWE info to send the Association Response to the peer. This OWE info in the command interface carries the IEs that include PMKID of the peer if the PMKSA is still valid or an updated DH IE for generating a new PMKSA with the peer.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This interface allows the host driver to offload OWE processing to user space. This intends to support OWE/Enhanced Open AKM by the host drivers that implement SME but rely on the user space for the crypotographic/OWE processing.Such drivers are not capable of processing/deriving the DH IE's. This interface acts as both the event from the driver to userspace and a command from userspace to the driver. Host driver shall use the event to notify the OWE info of the peer to the userspace for the cryptographic processing of the DH ie's. Accordingly, the userspace shall update the OWE info/DH ie's to the host driver corresponding to the peer. Above sequence aims for the AP mode where the event carries the OWE info of the peer(STA) obtained in the Assoc Request. The request interface from the userspace shall update the OWE info to the host driver, which is used to send the Assoc response to the peer. This OWE info in the command interface shall contain the ie's which either include the pmkid of the peer if the PMKSA is still valid or an updated DH ie's for generating a new PMKSA with the peer.

* nl80211: Allow set/del pmksa operations for APLiangwei Dong2019-02-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Host drivers may offload authentication to the user space through the commit ("cfg80211: Authentication offload to user space in AP mode"). This interface can be used to implement SAE by having the userspace do authentication/PMKID key derivation and driver handle the association. A step ahead, this interface can get further optimized if the PMKID is passed to the host driver and also have it respond to the association request by the STA on a valid PMKID. This commit enables the userspace to pass the PMKID to the host drivers through the set/del pmksa operations in AP mode. Set/Del pmksa is now restricted to STA/P2P client mode only and thus the drivers might not expect them in any other(AP) mode. This commit also introduces a feature flag NL80211_EXT_FEATURE_AP_PMKSA_CACHING (johannes: renamed) to maintain the backward compatibility of such an expectation by the host drivers. These operations are allowed in AP mode only when the drivers advertize the capability through this flag.

* cfg80211: Authentication offload to user space in AP modeSrinivas Dasari2019-02-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 40cbfa90218b ("cfg80211/nl80211: Optional authentication offload to userspace")' introduced authentication offload to user space by the host drivers in station mode. This commit extends the same for the AP mode too. Extend NL80211_ATTR_EXTERNAL_AUTH_SUPPORT to also claim the support of external authentication from the user space in AP mode. A new flag parameter is introduced in cfg80211_ap_settings to intend the same while "start ap". Host driver to use NL80211_CMD_FRAME interface to transmit and receive the authentication frames to / from the user space. Host driver to indicate the flag NL80211_RXMGMT_FLAG_EXTERNAL_AUTH while sending the authentication frame to the user space. This intends to the user space that the driver wishes it to process the authentication frame for certain protocols, though it had initially advertised the support for SME functionality. User space shall accordingly do the authentication and indicate its final status through the command NL80211_CMD_EXTERNAL_AUTH. Allow the command even if userspace doesn't include the attribute NL80211_ATTR_SSID for AP interface. Host driver shall continue with the association sequence and indicate the STA connection status through cfg80211_new_sta. To facilitate the host drivers in AP mode for matching the pmkid by the stations during the association, NL80211_CMD_EXTERNAL_AUTH is also enhanced to include the pmkid to drivers after the authentication. This pmkid can also be used in the STA mode to include in the association request. Also modify nl80211_external_auth to not mandate SSID in AP mode.

* cfg80211/nl80211: Optional authentication offload to userspaceSrinivas Dasari2019-01-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This interface allows the host driver to offload the authentication to user space. This is exclusively defined for host drivers that do not define separate commands for authentication and association, but rely on userspace SME (e.g., in wpa_supplicant for the ~WPA_DRIVER_FLAGS_SME case) for the authentication to happen. This can be used to implement SAE without full implementation in the kernel/firmware while still being able to use NL80211_CMD_CONNECT with driver-based BSS selection. Host driver sends NL80211_CMD_EXTERNAL_AUTH event to start/abort authentication to the port on which connect is triggered and status of authentication is further indicated by user space to host driver through the same command response interface. User space entities advertise this capability through the NL80211_ATTR_EXTERNAL_AUTH_SUPP flag in the NL80211_CMD_CONNECT request. Host drivers shall look at this capability to offload the authentication.

| | | | | | | | | | | | | | | | | | | | | | | | Disconnect or deauthenticate when the owning socket is closed if this flag is supplied to CMD_CONNECT or CMD_ASSOCIATE. This may be used to ensure userspace daemon doesn't leave an unmanaged connection behind. In some situations it would be possible to account for that, to some degree, in the deamon restart code or in the up/down scripts without the use of this attribute. But there will be systems where the daemon can go away for varying periods without a warning due to local resource management.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 814596495dd2b9d4aab92d8f89cf19060d25d2ea upstream. wiphy names were recently limited to 128 bytes by commit a7cfebcb7594 ("cfg80211: limit wiphy names to 128 bytes"). As it turns out though, this isn't sufficient because dev_vprintk_emit() needs the syslog header string "SUBSYSTEM=ieee80211\0DEVICE=+ieee80211:$devname" to fit into 128 bytes. This triggered the "device/subsystem name too long" WARN when the device name was >= 90 bytes. As before, this was reproduced by syzbot by sending an HWSIM_CMD_NEW_RADIO command to the MAC80211_HWSIM generic netlink family. Fix it by further limiting wiphy names to 64 bytes.

| * cfg80211: limit wiphy names to 128 bytesJohannes Berg2018-05-26

There's currently no limit on wiphy names, other than netlink message size and memory limitations, but that causes issues when, for example, the wiphy name is used in a uevent, e.g. in rfkill where we use the same name for the rfkill instance, and then the buffer there is "only" 2k for the environment variables. This was reported by syzkaller, which used a 4k name. Limit the name to something reasonable, I randomly picked 128.

But the same is not explicitly stated in FCC DFS requirement. Also, Pre-CAC requriements are not explicitly mentioned in FCC requirement. Current implementation in keeping DFS channel in available state is same as described in ETSI domain. For non-ETSI DFS domain, this patch gives a grace period of 2 seconds since the completion of successful CAC before moving the channel's DFS state to 'usable' from 'available' state. The same grace period is checked against the channel's dfs_state_entered timestamp while deciding if a DFS channel is available for operation. There is a new radar event, NL80211_RADAR_PRE_CAC_EXPIRED, reported when DFS channel is moved from available to usable state after the grace period. Also make sure the DFS channel state is reset to usable once the beaconing operation on that channel is brought down (like stop_ap, leave_ibss and leave_mesh) in non-ETSI domain.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, the status parameter to cfg80211_connect_result() was documented as using WLAN_STATUS_UNSPECIFIED_FAILURE (1) when the real status code for the failure is not known. This value can be used by an AP (and often is) and as such, user space cannot distinguish between explicitly rejected authentication/association and not being able to even try to associate or not receiving a response from the AP. Add a new inline function, cfg80211_connect_timeout(), to be used when the driver knows that the connection attempt failed due to a reason where connection could not be attempt or no response was received from the AP. The internal functions now allow a negative status value (-1) to be used as an indication of this special case. This results in the NL80211_ATTR_TIMED_OUT to be added to the NL80211_CMD_CONNECT event to allow user space to determine this case was hit. For backwards compatibility, NL80211_STATUS_CODE with the value WLAN_STATUS_UNSPECIFIED_FAILURE is still indicated in the event in such a case.

Applications fill the random transmit address in the frame buffer in the NL80211_CMD_FRAME command. This can be used only with the drivers that indicate support for random local address by setting the new NL80211_EXT_FEATURE_MGMT_TX_RANDOM_TA and/or NL80211_EXT_FEATURE_MGMT_TX_RANDOM_TA_CONNECTED in ext_features. The driver needs to configure receive behavior to accept frames to the specified random address during the time the frame exchange is pending and such frames need to be acknowledged similarly to frames sent to the local permanent address when this random address functionality is not used.

When both the features are enabled, both the BSSID and the local MAC address were getting same value causing Probe Request frames to go with unintended DA. Hence, this has been fixed by using a different NL80211_ATTR_BSSID attribute to set the specific BSSID (which was the more recent addition in cfg80211) for a scan. Backwards compatibility with old userspace software is maintained to some extent by allowing NL80211_ATTR_MAC to be used to set the specific BSSID when scanning without enabling random MAC address use. Scanning with random source MAC address was introduced by commit ad2b26abc157 ("cfg80211: allow drivers to support random MAC addresses for scan") and the issue was introduced with the addition of the second user for the same attribute in commit 818965d39177 ("cfg80211: Allow a scan request for a specific BSSID").

If it is specified, then any beacon interval for an interface in the interface combination as well as the GCD of all active beacon intervals in the combination must be greater or equal to this value.

* | cfg80211: Allow a scan request for a specific BSSIDJouni Malinen2016-08-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This allows scans for a specific BSSID to be optimized by the user space application by requesting the driver to set the Probe Request frame BSSID field (Address 3) to the specified BSSID instead of the wildcard BSSID. This prevents other APs from replying which reduces airtime need and latency in getting the response from the target AP through. This is an optimization and as such, it is acceptable for some of the drivers not to support the mechanism. If not supported, the wildcard BSSID will be used and more responses may be received.

* | cfg80211: basic support for PBSS network typeLior David2016-04-05
|/ | | | | | | | | | | | | | | | | | | | | | | PBSS (Personal Basic Service Set) is a new BSS type for DMG networks. It is similar to infrastructure BSS, having an AP-like entity called PCP (PBSS Control Point), but it has few differences. PBSS support is mandatory for 11ad devices. Add support for PBSS by introducing a new PBSS flag attribute. The PBSS flag is used in the START_AP command to request starting a PCP instead of an AP, and in the CONNECT command to request connecting to a PCP instead of an AP.

* cfg80211: Add multiple scan plans for scheduled scanAvraham Stern2015-10-13
| | | | | | | | | | | | | | | | | | | | | | | 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.

* nl80211: allow BSS data to include CLOCK_BOOTTIME timestampDmitry Shmidt2015-10-13
| | | | | | | | | | | | | | | | | | | For location and connectivity services, userspace would often like to know the time when the BSS was last seen. The current "last seen" value is calculated in a way that makes it less useful, especially if the system suspended in the meantime. Add the ability for the driver to report a real CLOCK_BOOTTIME stamp that can then be reported to userspace (if present). Drivers wishing to use this must be converted to the new API to call cfg80211_inform_bss_data() or cfg80211_inform_bss_frame_data(). They need to ensure the reported value is accurate enough even when the frame might have been buffered in the device (e.g. firmware.)

* cfg80211: Add API to change the indoor regulatory settingIlan peer2015-03-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, the indoor setting configuration assumed that as long as a station interface is connected, the indoor environment setting does not change. However, this assumption is problematic as: - It is possible that a station interface is connected to a mobile AP, e.g., softAP or a P2P GO, where it is possible that both the station and the mobile AP move out of the indoor environment making the indoor setting invalid. In such a case, user space has no way to invalidate the setting. - A station interface disconnection does not necessarily imply that the device is no longer operating in an indoor environment, e.g., it is possible that the station interface is roaming but is still stays indoor. To handle the above, extend the indoor configuration API to allow user space to indicate a change of indoor settings, and allow it to indicate weather it controls the indoor setting, such that: 1. If the user space process explicitly indicates that it is going to control the indoor setting, do not clear the indoor setting internally, unless the socket is released. The user space process should use the NL80211_ATTR_SOCKET_OWNER attribute in the command to state that it is going to control the indoor setting. 2. Reset the indoor setting when restoring the regulatory settings in case it is not owned by a user space process. Based on the above, a user space tool that continuously monitors the indoor settings, i.e., tracking power setting, location etc., can indicate environment changes to the regulatory core. It should be noted that currently user space is the only provided mechanism used to hint to the regulatory core over the indoor/outdoor environment -- while the country IEs do have an environment setting this has been completely ignored by the regulatory core by design for a while now since country IEs typically can contain bogus data.

* nl80211: prohibit mixing 'any' and regular wowlan triggersJohannes Berg2015-03-04
| | | | | | | | | | | | | | | | | | | | | | | If the device supports waking up on 'any' signal - i.e. it continues operating as usual and wakes up the host on pretty much anything that happens, then it makes no sense to also configure the more restricted WoWLAN mode where the device operates more autonomously but also in a more restricted fashion. Currently only cw2100 supports both 'any' and other triggers, but it seems to be broken as it doesn't configure anything to the device, so we can't currently get into a situation where both even can correctly be configured. This is about to change (Intel devices are going to support both and have different behaviour depending on configuration) so make sure the conflicting modes cannot be configured. (It seems that cw2100 advertises 'any' and 'disconnect' as a means of saying that's what it will always do, but that isn't really the way this API was meant to be used nor does it actually mean anything as 'any' always implies 'disconnect' already, and the driver doesn't change device configuration in any way depending on the settings.)

* nl/mac80211: allow zero plink timeout to disable STA expirationMasashi Honma2015-02-28
| | | | | | | | | | | | | | | | | | | | | | | | Both wpa_supplicant and mac80211 have and inactivity timer. By default wpa_supplicant will be timed out in 5 minutes and mac80211's it is 30 minutes. If wpa_supplicant uses a longer timer than mac80211, it will get unexpected disconnection by mac80211. Using 0xffffffff instead as the configured value could solve this w/o changing the code, but due to integer overflow in the expression used this doesn't work. The expression is: (current jiffies) > (frame Rx jiffies + NL80211_MESHCONF_PLINK_TIMEOUT * 250) On 32bit system, the right side would overflow and be a very small value if NL80211_MESHCONF_PLINK_TIMEOUT is sufficiently large, causing unexpectedly early disconnections. Instead allow disabling the inactivity timer to avoid this situation, by passing the (previously invalid and useless) value 0.

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.
