Subject: 'iw events' stops receiving events after a while on 4.9 + hacks
Date: Tue, 16 May 2017 10:12:37 -0700	[thread overview]
Message-ID: <d82d191e-8ede-68c6-c9e0-c381dc874d36@candelatech.com> (raw)

I have been keeping an 'iw events' program running with a perl script gathering its
output and post-processing it.  This has been working for several years on 4.7 and earlier
kernels, but when testing on 4.9 overnight, I notice that 'iw events' is not showing any input.  'strace' shows
that it is waiting on recvmsg.  If I start a second 'iw events' then it will get
wifi events as expected.

Are there any known issues in this area?

Thanks,
Ben
