openssh unix dev - Jul 2016 - Question about Calling packet_close from cleanup_exitfunction

Hi,

Just out of interest, is it okay to call packet_close from cleanup_exit
function in sshd.c. For a project that I'm working on I need to clear the
sensitive information held on the server side before exiting.

Thanks,
Mahoda

It looks like it will be safe if the packet code has been properly
initialised AND whatever you are doing doesn't involve threads AND
you're not calling it from anything like a signal handler.
