commit 0dc267b13f3a7e8424a898815dd357211b737330 upstream. TKIP Michael MIC was not verified properly for PCIe cases since the validation steps in ieee80211_rx_h_michael_mic_verify() in mac80211 did not get fully executed due to unexpected flag values in ieee80211_rx_status. Fix this by setting the flags property to meet mac80211 expectations for performing Michael MIC validation there. This fixes CVE-2020-26141. It does the same as ath10k_htt_rx_proc_rx_ind_hl() for SDIO which passed MIC verification case. This applies only to QCA6174/QCA9377 PCIe.

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.
