Mikhail Lobanov 3bcb702977 wifi: mac80211: check basic rates validity in sta_link_apply_parameters 
commit 16ee3ea8fa upstream.

When userspace sets supported rates for a new station via
NL80211_CMD_NEW_STATION, it might send a list that's empty
or contains only invalid values. Currently, we process these
values in sta_link_apply_parameters() without checking the result of
ieee80211_parse_bitrates(), which can lead to an empty rates bitmap.

A similar issue was addressed for NL80211_CMD_SET_BSS in commit
ce04abc3fc ("wifi: mac80211: check basic rates validity").
This patch applies the same approach in sta_link_apply_parameters()
for NL80211_CMD_NEW_STATION, ensuring there is at least one valid
rate by inspecting the result of ieee80211_parse_bitrates().

Found by Linux Verification Center (linuxtesting.org) with Syzkaller.

[ Summary of conflict resolutions:
  - The function ieee80211_parse_bitrates() takes channel width as
    its first parameter, and the chandef struct has been refactored
    in kernel version 6.9, in commit
    6092077ad0 so that the width is
    contained in chanreq.oper.width. In kernel version 6.1 the
    width parameter is defined directly in the chandef struct. ]

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.

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.
