Subject: [PATCH 2/2] main: die when cannot drop privileges
|
|
||||||
|
|
||||||
If `run_as` parameter is set but the user is missing in the system,
|
|
||||||
keylime will log an ERROR when trying to drop privileges, but continue
|
|
||||||
the execution as the current user (usually `root`). This can be a
|
|
||||||
security issue, as the agent is running "silently" as a privileged user.
|
|
||||||
|
|
||||||
This commit stop the execution if an error is found when dropping
|
|
||||||
privileges for the agent service, and present an `info!` message with
|
|
||||||
the current user and group.
|
|
||||||
|
