pscap - a program to see capabilities
pscap [ -a ] [ -p pid ] [ --tree ]
pscap is a program that prints out a report of process
capabilities. If the application has any capabilities, it will be
in the report. By giving a pid with the -p command line option,
only the process specified with the pid is reported. If a process
is not in the report, it has dropped all capabilities. If the
process has partial capabilities, it is further examined to see if
it has an open-ended bounding set. If this is found to be true, a
'+' symbol is added. If the process has ambient capabilities, an
'@' symbol is added.
The command name in the output may be followed by an asterisk mark
(*). This mark denotes processes which run in child user
namespaces (relative to the user namespace of pscap itself).
The --tree option causes the output of the program to be mapped
into a tree structure so that the relationships between processes
can be studied to see what capabilities might be leaked to child
processes. In tree mode, each process label is shown as
command(pid:account).
