When the user-space crda daemon fails to respond to kernel queries, the kernel crda subsystem will stall, refusing any further regulatory hints. Details are in the description of the patch itself. The patch proposes a fix to the problem by adding a timeout to the user-space crda accesses, reverting to the 00 domain if user space fails to respond. This seems safe assuming we don't know what the rules of the requested domain and allows further regulatory hints to be processed again. In my testing, this patch appears to function in the various scenarios I can produce (user hints and 11d hints.) My understanding of the crda subsystem is still relatively shallow, so I'm asking for your thoughts on this approach. Comments will be appreaciated!
