iwd on my raspberry pi zero started to crash after upgrade to iwd 1.22: Program terminated with signal SIGSEGV, Segmentation fault. #0 0x000211c4 in netdev_connect_event (msg=<optimized out>, netdev=0x2016940) at src/netdev.c:2915 2915 if (is_offload(hs) && handshake_event(hs, HANDSHAKE_EVENT_SETTING_KEYS)) (gdb) bt #0 0x000211c4 in netdev_connect_event (msg=<optimized out>, netdev=0x2016940) at src/netdev.c:2915 #1 0x76f11220 in process_multicast (nlmsg=0x7e8acafc, group=<optimized out>, genl=<optimized out>) at ell/genl.c:1029 #2 received_data (io=<optimized out>, user_data=<optimized out>) at ell/genl.c:1096 #3 0x76f0da08 in io_callback (fd=<optimized out>, events=1, user_data=0x200a560) at ell/io.c:120 #4 0x76f0ca78 in l_main_iterate (timeout=<optimized out>) at ell/main.c:478 #5 0x76f0cb74 in l_main_run () at ell/main.c:525 #6 l_main_run () at ell/main.c:507 #7 0x76f0cdd4 in l_main_run_with_signal (callback=callback@entry=0x18c94 <signal_handler>, user_data=user_data@entry=0x0) at ell/main.c:647 #8 0x00018178 in main (argc=<optimized out>, argv=<optimized out>) at src/main.c:532 I suppose hs being NULL is the reason. Disabling handshake offloading in brcmfmac fixes crash.
