rpm_execcon(3) -- Linux man page
NAMEgetexeccon, setexeccon - get or set the SE Linux security context used for executing a new process.
int getexeccon(security_context_t *context);
int setexeccon(security_context_t context);
int rpm_execcon(unsigned int verified, const char *filename, char *const argv , char *const envp);
DESCRIPTIONgetexeccon retrieves the context used for executing a new process. This returned context should be freed with freecon if non-NULL. getexeccon sets *con to NULL if no exec context has been explicitly set by the program (i.e. using the default policy behavior).
sets the context used for the next execve call.
NULL can be passed to
setexeccon to reset to the default policy behavior.
The exec context is automatically reset after the next execve, so a
program doesn't need to explicitly sanitize it upon startup.
setexeccon can be applied prior to library
functions that internally perform an execve, e.g. execl*, execv*, popen,
in order to set an exec context for that operation.
Note: Signal handlers that perform an execve must take care to
save, reset, and restore the exec context to avoid unexpected behaviors.
rpm_execcon Execute a helper for rpm in an appropriate security context.
RETURN VALUEOn error -1 is returned.
On success getexeccon and setexeccon returns 0.
