Subject: [WEXT]: multiple calls for SIOCGIWSTATS return same value
Date: Sat, 6 Jun 2015 20:37:21 -0600 [thread overview]
Message-ID: <20150606203721.28791bb3@erg.abdn.ac.uk> (raw)
A problem has been found in recent kernels where multiple
calls using SIOCGIWSTATS return the same, identical value.
This behaviour is observable both using 'iwconfig <dev>'
and wavemon info screen, where it was reported in [1].
It looks as if this is a WEXT issue, since on the same
system multiple 'iw dev <devname> station dump' calls
return different signal level values.
I can confirm the behaviour on davem 4.1.0-rc6 net tree
at commit c46a024ea5, it has been reported on [1] for
fedora 21 with kernel-4.0.4-201/2 as well.
That report also stated that the behaviour does not occur
on kernel-3.19.7-200. Have not had time to bisect yet.
Thanks for any hints that can help resolve this.
