Subject: wlcore: check ssid length against the correct element
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=faae5aae2d4d7fe976d6ef62c3c209b8990124ac;p=openwrt%2Fstaging%2Fblogic.git

wlcore: check ssid length against the correct element

commit 587cc28 ("wlcore: compare ssid_len before comparing
ssids") introduced a new bug - the ssid length from the
request struct was compared against the ssid length of
another request, instead the one of the cmd.

This might cause the sched scan request to fail
(with -EINVAL) in many cases.
