Subject: [PATCH AUTOSEL 4.19 13/47] mwifiex: Properly initialize private structure on interface type changes
Date: Mon, 8 Nov 2021 12:49:57 -0500 [thread overview]
Message-ID: <20211108175031.1190422-13-sashal@kernel.org> (raw)
In-Reply-To: <20211108175031.1190422-1-sashal@kernel.org>
From: Jonas Dreßler <verdre@v0yd.nl>
[ Upstream commit c606008b70627a2fc485732a53cc22f0f66d0981 ]
When creating a new virtual interface in mwifiex_add_virtual_intf(), we
update our internal driver states like bss_type, bss_priority, bss_role
and bss_mode to reflect the mode the firmware will be set to.
When switching virtual interface mode using
mwifiex_init_new_priv_params() though, we currently only update bss_mode
and bss_role. In order for the interface mode switch to actually work,
we also need to update bss_type to its proper value, so do that.
This fixes a crash of the firmware (because the driver tries to execute
commands that are invalid in AP mode) when switching from station mode
to AP mode.
