I've just started working on a related, yet different, feature. It is possible
that the feature this bug talks about could fall out from that work or be a
small addition to it.
I'm work on providing the ability to do something like:
probe process("/bin/program_of_interest").create {
# do something here...
}
probe process("/bin/program_of_interest").exit {
# do something here...
}
(I'm undecided on the exact syntax, so feel free to suggest something better.)
This will give you the capability to attach to existing or new instances of
/bin/program_of_interest system-wide. I'm attempting to do this just with utrace.
In terms of what I'm working on, I think your requested feature becomes:
1. use utrace to watch the pid of the shell (instead of the entire system)
2. look for the exec of 'pgm'
3. attach the user utrace/uprobes probes to the newly created 'pgm'
Is this what you are looking for?
