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.
me too, also seen on 4.4 - i'am happy for debug ideas. bye, bastian
