Heya, I have a particularly stubborn device, the TomTom Go Remote that tries to connect to my computer as soon as it's turned on, even when I've removed the pairing on the computer side. With GNOME's Bluetooth wizard open, I receive an out of the blue request for pairing, I pass it the expected PIN code (0000), I then find that the wizard doesn't work as I expected and turn it off. bluetoothd promptly crashes: Program received signal SIGSEGV, Segmentation fault. 0x00007f0cf9ffde24 in agent_auth_cb (agent=<optimized out>, derr=0x7fffab655920, user_data=0x7f0cfb2e0020) at src/adapter.c:4370 4370 struct service_auth *auth = adapter->auths->head->data; (gdb) p adapter $1 = (struct btd_adapter *) 0x7f0cfb2e0020 (gdb) p adapter->auths $2 = (GQueue *) 0x7f0cfb2d1240 (gdb) p adapter->auths->head $3 = 0x0 Some missing NULL checks? I imagine that this should be reproduceable using simple-agent and making it exit after replying to RequestPinCode. This happens with 5.10 and 5.11: https://retrace.fedoraproject.org/faf/problems/1353319/ Cheers -- To unsubscribe from this list: send the line "unsubscribe linux-bluetooth" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
