crash while cancelling an in-progress connection
I have a situation where the user has sent a connection to an open AP. Before connman returns that the connection has completed, the user attempts to cancel the connection. According to the documentation the net.connman.Service.Disconnect "can also be used to abort a previous connection attempt via the Connect method." The issue is that when I attempt this, that after I make the dbus call to disconnect, and before the disconnect call returns I get a segmentation fault. The stack is hammered enough that the only traceback information is that it happens in libdbus-1.so.3. This only happens when I try to cancel a connection on an open AP. Cancelling all other attempts have worked to this point. Is there something that I need to set a guard around so this doesn't happen?

Hi, I have a situation where the user has sent a connection to an open AP. Before connman returns that the connection has completed, the user attempts to cancel the connection.

Cancelling all other attempts have worked to this point. Is there something that I need to set a guard around so this doesn't happen? What version of connman and wpa_supplicant are you using? Also, please provide any relevant logs you could have (the backtrace and so on). Try running connman this way: CONNMAN_SUPPLICANT_DEBUG=1 connmand -n -d &> connman_log.txt and paste the logs somewhere.

Could you compile connman with debugging enabled and optimization disabled, and debug the issue with valgrind? Once the issue is reproducible that will help a lot in understanding what goes wrong.
