Subject: [RFC 0/1] Hwsim crash when receiving cloned frame
Date: Thu, 10 Sep 2020 16:57:06 -0700	[thread overview]
Message-ID: <20200910235707.7732-1-prestwoj@gmail.com> (raw)

I am unsure if this is the proper way to fix this problem since it
ends up just dropping the frame when this happens. If 'channel'
*should* be initialized by the time we are receiving frames then
there may be a race somewhere. If its functionally ok for 'channel'
to be NULL, then maybe this fix is alright.

I realize it had been suggested to provide a decoded crash with
a debuggable kernel, but I really dont see how that could provide
any additional information above what is here. Because of this I
sent as an RFC and we can discuss further if needed.
