NAME
       getexeccon, setexeccon - get or set the SE Linux security context used
       for executing a new process.


SYNOPSIS
       #include <selinux/selinux.h>

       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[]);


DESCRIPTION
       getexeccon  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).

       setexeccon 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	 pro-
       gram 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	 con-
       text.


RETURN VALUE
       On error -1 is returned.

       On success getexeccon and setexeccon returns 0.
