Aloka Dixit d12d193fe1 wifi: mac80211: do not use old MBSSID elements [ Upstream commit `a519be2f5d` ] When userspace brings down and deletes a non-transmitted profile, it is expected to send a new updated Beacon template for the transmitted profile of that multiple BSSID (MBSSID) group which does not include the removed profile in MBSSID element. This update comes via NL80211_CMD_SET_BEACON. Such updates work well as long as the group continues to have at least one non-transmitted profile as NL80211_ATTR_MBSSID_ELEMS is included in the new Beacon template. But when the last non-trasmitted profile is removed, it still gets included in Beacon templates sent to driver. This happens because when no MBSSID elements are sent by the userspace, ieee80211_assign_beacon() ends up using the element stored from earlier Beacon template. Do not copy old MBSSID elements, instead userspace should always include these when applicable.

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 reStructuredText markup notation.

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.
