Brian Norris bb902b6c87 mwifiex: Don't abort on small, spec-compliant vendor IEs 
commit 63d7ef3610 upstream.

Per the 802.11 specification, vendor IEs are (at minimum) only required
to contain an OUI. A type field is also included in ieee80211.h (struct
ieee80211_vendor_ie) but doesn't appear in the specification. The
remaining fields (subtype, version) are a convention used in WMM
headers.

Thus, we should not reject vendor-specific IEs that have only the
minimum length (3 bytes) -- we should skip over them (since we only want
to match longer IEs, that match either WMM or WPA formats). We can
reject elements that don't have the minimum-required 3 byte OUI.

While we're at it, move the non-standard subtype and version fields into
the WMM structs, to avoid this confusion in the future about generic
"vendor header" attributes.

Fixes: 685c9b7750 ("mwifiex: Abort at too short BSS descriptor element")

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.
