* | cfg80211: adapt to new channelization of the 6GHz bandArend Van Spriel2020-05-311-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The 6GHz band does not have regulatory approval yet, but things are moving forward. However, that has led to a change in the channelization of the 6GHz band which has been accepted in the 11ax specification. It also fixes a missing MHZ_TO_KHZ() macro for 6GHz channels while at it. This change is primarily thrown in to discuss how to deal with it. I noticed ath11k adding 6G support with old channelization and ditto for iw. It probably involves changes in hostapd as well.

* | cfg80211: fix 6 GHz frequencies to kHzJohannes Berg2020-05-311-1/+1
| | | | | | | | | | | | | | | | | | | | | | The updates to change to kHz frequencies and the 6 GHz additions evidently overlapped (or rather, I didn't see it when applying the latter), so the 6 GHz is broken. Fix this.

* | cfg80211: fix CFG82011_CRDA_SUPPORT still mentioning internal regdbPatrick Steinhardt2020-05-271-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Back with commit c8c240e284b3 (cfg80211: reg: remove support for built-in regdb, 2015-10-15), support for using CFG80211_INTERNAL_REGDB was removed in favor of loading the regulatory database as firmware file. The documentation of CFG80211_CRDA_SUPPORT was not adjusted, though, which is why it still mentions mentions the old way of loading via the internal regulatory database. Remove it so that the kernel option only mentions using the firmware file.

* | cfg80211: Replace zero-length array with flexible-arrayGustavo A. R. Silva2020-05-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] sizeof(flexible-array-member) triggers a warning because flexible array members have incomplete type[1]. There are some instances of code in which the sizeof operator is being incorrectly/erroneously applied to zero-length arrays and the result is zero. Such instances may be hiding some bugs. So, this work (flexible-array member conversions) will also help to get completely rid of those sorts of issues. This issue was found with the help of Coccinelle.

* | nl80211: support scan frequencies in KHzThomas Pedersen2020-05-271-12/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the driver advertises NL80211_EXT_FEATURE_SCAN_FREQ_KHZ userspace can omit NL80211_ATTR_SCAN_FREQUENCIES in favor of an NL80211_ATTR_SCAN_FREQ_KHZ. To get scan results in KHz userspace must also set the NL80211_SCAN_FLAG_FREQ_KHZ.

This seems to indicate the API is wrong, and we should maintain the full information in cfg80211 instead of the drivers. Change the API to no longer inform the driver about individual registrations and unregistrations, but rather every time about the entire state of the entire wiphy and single wdev, whenever it may have changed. This also simplifies the code in cfg80211 as it no longer has to track exactly what was unregistered and can free things immediately.

* | cfg80211: Configure PMK lifetime and reauth threshold for PMKSA entriesVeerendranath Jakkam2020-03-201-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Drivers that trigger roaming need to know the lifetime of the configured PMKSA for deciding whether to trigger the full or PMKSA cache based authentication. The configured PMKSA is invalid after the PMK lifetime has expired and must not be used after that and the STA needs to disassociate if the PMK expires. Hence the STA is expected to refresh the PMK with a full authentication before this happens (e.g., when reassociating to a new BSS the next time or by performing EAPOL reauthentication depending on the AKM) to avoid unnecessary disconnection. The PMK reauthentication threshold is the percentage of the PMK lifetime value and indicates to the driver to trigger a full authentication roam (without PMKSA caching) after the reauthentication threshold time, but before the PMK timer has expired. Authentication methods like SAE need to be able to generate a new PMKSA entry without having to force a disconnection after this threshold timeout. If no roaming occurs between the reauthentication threshold time and PMK lifetime expiration, disassociation is still forced. The new attributes for providing these values correspond to the dot11 MIB variables dot11RSNAConfigPMKLifetime and dot11RSNAConfigPMKReauthThreshold. This type of functionality is already available in cases where user space component is in control of roaming. This commit extends that same capability into cases where parts or all of this functionality is offloaded to the driver.

* | cfg80211: Add support for userspace to reset stations in IBSS modeNicolas Cavallari2020-03-201-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sometimes, userspace is able to detect that a peer silently lost its state (like, if the peer reboots). wpa_supplicant does this for IBSS-RSN by registering for auth/deauth frames, but when it detects this, it is only able to remove the encryption keys of the peer and close its port. However, the kernel also hold other state about the station, such as BA sessions, probe response parameters and the like. They also need to be resetted correctly. This patch adds the NL80211_EXT_FEATURE_DEL_IBSS_STA feature flag indicating the driver accepts deleting stations in IBSS mode, which should send a deauth and reset the state of the station, just like in mesh point mode.

* | nl80211: add no pre-auth attribute and ext. feature flag for ctrl. portMarkus Theil2020-03-201-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the nl80211 control port is used before this patch, pre-auth frames (0x88c7) are send to userspace uncoditionally. While this enables userspace to only use nl80211 on the station side, it is not always useful for APs. Furthermore, pre-auth frames are ordinary data frames and not related to the control port. Therefore it should for example be possible for pre-auth frames to be bridged onto a wired network on AP side without touching userspace. For backwards compatibility to code already using pre-auth over nl80211, this patch adds a feature flag to disable this behavior, while it remains enabled by default. An additional ext. feature flag is added to detect this from userspace. Thanks to Jouni for pointing out, that pre-auth frames should be handled as ordinary data frames.
