[sudo-users] How sudo handles signals

[Todd C. Miller]

I don't see that behavior myself, but from the code it seems possible
if you do not have log_output enabled.

The main sudo process forwards signals to the command it is running
which is fine in general.  However, in the case of keyboard-generated
signals it may be possible for both processes to receive SIGINT and
thus for the command to get the signal twice.  As I said, I don't
see that with a simple test program.  Can you share the code you
are using?
