Previous implementation of SAE authentication in infrastructure BSS was somewhat restricting and not exactly clean way of handling the two auth() operations. This ended up removing and re-adding the STA entry for the AP in the middle of authentication and also messing up authentication state tracking through the sequence of four Authentication frames. Furthermore, this did not work if the AP ended up sending out SAE Confirm (auth trans #2) immediately after SAE Commit (auth trans #1) before the station had time to transmit its SAE Confirm. Clean up authentication state handling for the SAE case to allow two rounds of auth() calls without dropping all state between those operations. Track peer Confirmed status and mark authentication completed only once both ends have confirmed. ieee80211_mgd_auth() check for EBUSY cases is now handling only the pending association (ifmgd->assoc_data) while all pending authentication (ifmgd->auth_data) cases are allowed to proceed to allow user space to start a new connection attempt from scratch even if the previously requested authentication is still waiting completion. This is needed to avoid making SAE error cases with retries take excessive amount of time with no means for the user space to stop that (apart from setting the netdev down). As an extra bonus, the end of ieee80211_rx_mgmt_auth() can be cleaned up to avoid the extra copy of the cfg80211_rx_mlme_mgmt() call for ongoing SAE authentication since the new ieee80211_mark_sta_auth() helper function can handle both completion of authentication and updates to the STA entry under the same condition and there is no need to return from the function between those operations.

README
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
