commit 73f52eb43a66f78c21bd8e61bd25f63415f396f0
Author: Dave Brolley <brolley@redhat.com>
Date: Mon Jan 30 13:40:16 2012 -0500
PR 13631 and other rework of multi-privilege level support
- PR 13631 - Detection of Reqested Privilege Level in stap-server
- Parsing of the client's command now uses getopt_long and shares
the getopt input with session.cxx
- cmdline.cxx, cmdline.h
- Do not allow multiple privilege-setting options to specify
different privilege levels.
- No longer a need for stap-serverd to generate a --privilege
option for the spawned stap.
- stap-serverd cannot (and no longer does) rely on knowledge of
the highest signed privilege level when evaluating the user's
credentials.
- Simplified user credentials test against those required by the module
in stap-serverd.
- Some kernel.* probes were being registered for use by stapdev only.
Corrected to be stapdev | stapsys.
- Corrected testsuite problem which was hiding this bug.
