2021-10-25cfg80211: fix management registrations lockingJohannes Berg
The management registrations locking was broken, the list was locked for each wdev, but cfg80211_mgmt_registrations_update() iterated it without holding all the correct spinlocks, causing list corruption. Rather than trying to fix it with fine-grained locking, just move the lock to the wiphy/rdev (still need the list on each wdev), we already need to hold the wdev lock to change it, so there's no contention on the lock in any case. This trivially fixes the bug since we hold one wdev's lock already, and now will hold the lock that protects all lists.

Add new attributes to configure support for multiple BSSID and advanced multi-BSSID advertisements (EMA) in AP mode. - NL80211_ATTR_MBSSID_CONFIG used for per interface configuration. - NL80211_ATTR_MBSSID_ELEMS used to MBSSID elements for beacons.

2021-09-27cfg80211: AP mode driver offload for FILS association cryptoSubrat Mishra
Add a driver FILS crypto offload extended capability flag to indicate that the driver running in AP mode is capable of handling encryption and decryption of (Re)Association request and response frames. Add a command to set FILS AAD data to driver. This feature is supported on drivers running in AP mode only. This extended capability is exchanged with hostapd during cfg80211 init. If the driver indicates this capability, then before sending the Authentication response frame, hostapd sets FILS AAD data to the driver. This allows the driver to decrypt (Re)Association Request frame and encrypt (Re)Association Response frame. FILS Key derivation will still be done in hostapd.

2021-02-01cfg80211: fix netdev registration deadlockJohannes Berg
If register_netdevice() fails after having called cfg80211's netdev notifier (cfg80211_netdev_notifier_call) it will call the notifier again with UNREGISTER. This would then lock the wiphy mutex because we're marked as registered, which causes a deadlock. Fix this by separately keeping track of whether or not we're in the middle of registering to also skip the notifier call on this unregister.

2021-01-26cfg80211: avoid holding the RTNL when calling the driverJohannes Berg
Currently, _everything_ in cfg80211 holds the RTNL, and if you have a slow USB device (or a few) you can get some bad lock contention on that. Fix that by re-adding a mutex to each wiphy/rdev as we had at some point, so we have locking for the wireless_dev lists and all the other things in there, and also so that drivers still don't have to worry too much about it (they still won't get parallel calls for a single device). Then, we can restrict the RTNL to a few cases where we add or remove interfaces and really need the added protection. Some of the global list management still also uses the RTNL, since we need to have it anyway for netdev management, but we only hold the RTNL for very short periods of time here.

2021-01-22cfg80211: change netdev registration/unregistration semanticsJohannes Berg
We used to not require anything in terms of registering netdevs with cfg80211, using a netdev notifier instead. However, in the next patch reducing RTNL locking, this causes big problems, and the simplest way is to just require drivers to do things better. Change the registration/unregistration semantics to require the drivers to call cfg80211_(un)register_netdevice() when this is happening due to a cfg80211 request, i.e. add_virtual_intf() or del_virtual_intf() (or if it somehow has to happen in any other cfg80211 callback). Otherwise, in other contexts, drivers may continue to use the normal netdev (un)registration functions as usual. Internally, we still use the netdev notifier and track (by the new wdev->registered bool) if the wdev had already been added to cfg80211 or not.

2020-12-11nl80211: add common API to configure SAR power limitationsCarl Huang
NL80211_CMD_SET_SAR_SPECS is added to configure SAR from user space. NL80211_ATTR_SAR_SPEC is used to pass the SAR power specification when used with NL80211_CMD_SET_SAR_SPECS. Wireless driver needs to register SAR type, supported frequency ranges to wiphy, so user space can query it. The index in frequency range is used to specify which sub band the power limitation applies to. The SAR type is for compatibility, so later other SAR mechanism can be implemented without breaking the user space SAR applications. Normal process is user space queries the SAR capability, and gets the index of supported frequency ranges and associates the power limitation with this index and sends to kernel. Here is an example of message send to kernel: 8c 00 00 00 08 00 01 00 00 00 00 00 38 00 2b 81 08 00 01 00 00 00 00 00 2c 00 02 80 14 00 00 80 08 00 02 00 00 00 00 00 08 00 01 00 38 00 00 00 14 00 01 80 08 00 02 00 01 00 00 00 08 00 01 00 48 00 00 00 NL80211_CMD_SET_SAR_SPECS: 0x8c NL80211_ATTR_WIPHY: 0x01(phy idx is 0) NL80211_ATTR_SAR_SPEC: 0x812b (NLA_NESTED) NL80211_SAR_ATTR_TYPE: 0x00 (NL80211_SAR_TYPE_POWER) NL80211_SAR_ATTR_SPECS: 0x8002 (NLA_NESTED) freq range 0 power: 0x38 in 0.25dbm unit (14dbm) freq range 1 power: 0x48 in 0.25dbm unit (18dbm) Signed-off-by: Carl Huang <cjhuang@codeaurora.org> Reviewed-by: Brian Norris <briannorris@chromium.org> Reviewed-by: Abhishek Kumar <kuabhs@chromium.org> Link: https://lore.kernel.org/r/20201203103728.3034-2-cjhuang@codeaurora.org [minor edits, NLA parse cleanups] Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2020-11-06cfg80211: Add support to configure SAE PWE value to driversRohan Dutta
Add support to configure SAE PWE preference from userspace to drivers in both AP and STA modes. This is needed for cases where the driver takes care of Authentication frame processing (SME in the driver) so that correct enforcement of the acceptable PWE derivation mechanism can be performed. The userspace applications can pass the sae_pwe value using the NL80211_ATTR_SAE_PWE attribute in the NL80211_CMD_CONNECT and NL80211_CMD_START_AP commands to the driver. This allows selection between the hunting-and-pecking loop and hash-to-element options for PWE derivation. For backwards compatibility, this new attribute is optional and if not included, the driver is notified of the value being unspecified.

git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media Pull documentation updates from Mauro Carvalho Chehab: "A series of patches addressing warnings produced by make htmldocs. This includes: - kernel-doc markup fixes - ReST fixes - Updates at the build system in order to support newer versions of the docs build toolchain (Sphinx) After this series, the number of html build warnings should reduce significantly, and building with Sphinx 3.1 or later should now be supported (although it is still recommended to use Sphinx 2.4.4). As agreed with Jon, I should be sending you a late pull request by the end of the merge window addressing remaining issues with docs build, as there are a number of warning fixes that depends on pull requests that should be happening along the merge window. The end goal is to have a clean htmldocs build on Kernel 5.10. PS. It should be noticed that Sphinx 3.0 is not currently supported, as it lacks support for C domain namespaces.
