    getexeccon

    
    
           rpm_execcon - run a helper for rpm in an appropriate security context
    
    
    

    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.  getex-
           eccon  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  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 behavior.
    
           rpm_execcon runs a helper for rpm in an appropriate  security  context.
           The  verified  parameter should contain the return code from the signa-
           ture verification (0 == ok, 1 == notfound, 2 == verifyfail, 3  ==  not-
           trusted,  4 == nokey), although this information is not yet used by the
           function.  The function determines the proper security context for  the
           helper  based  on  policy,  sets the exec context accordingly, and then
           executes the specified filename with the provided argument and environ-
           ment arrays.
    
    
    

    RETURN VALUE

           On error -1 is returned.
    
           On  success  getexeccon  and  setexeccon  returns  0.  rpm_execcon only
           returns upon errors, as it calls execve(2).
