SYNOPSIS

       #include <selinux/selinux.h>

       #include <selinux/flask.h>

       int security_compute_av(security_context_t scon, security_context_t tcon, security_class_t
       tclass, access_vector_t requested, struct av_decision *avd);

       int   security_compute_av_flags(security_context_t    scon,    security_context_t    tcon,
       security_class_t tclass, access_vector_t requested, struct av_decision *avd);

       int     security_compute_create(security_context_t    scon,    security_context_t    tcon,
       security_class_t tclass, security_context_t *newcon);

       int    security_compute_relabel(security_context_t    scon,    security_context_t    tcon,
       security_class_t tclass, security_context_t *newcon);

       int     security_compute_member(security_context_t    scon,    security_context_t    tcon,
       security_class_t tclass, security_context_t *newcon);

       int    security_compute_user(security_context_t    scon,     const     char     *username,
       security_context_t **con);

       int security_get_initial_context(const char *name, security_context_t "con );

       int selinux_check_passwd_access(access_vector_t requested);

       int checkPasswdAccess(access_vector_t requested);

DESCRIPTION

       security_compute_av  queries  whether the policy permits the source context scon to access
       the target context tcon via class tclass with the requested access vector.   The  decision
       is returned in avd.

       security_compute_av_flags  is  identical  to security_compute_av but additionally sets the
       flags field of avd.  Currently one flag is supported: SELINUX_AVD_FLAGS_PERMISSIVE,  which
       indicates the decision is computed on a permissive domain.

       security_compute_create is used to compute a context to use for labeling a new object in a
       particular class based on a SID pair.

       security_compute_relabel is used to compute the new context  to  use  when  relabeling  an
       object,  it  is  used in the pam_selinux.so source and the newrole source to determine the
       correct label for the tty at login time, but can be used for other things.

       security_compute_member  is  used  to  compute  the  context  to  use  when   labeling   a
       polyinstantiated object instance.

       security_compute_user  is  used  to determine the set of user contexts that can be reached
       from a source context. It is mainly used by get_ordered_context_list.

       security_get_initial_context is used to get the  context  of  a  kernel  initial  security
       identifier specified by name

       selinux_check_passwd_access  is  used  to  check  for  a  permission  in the passwd class.
       selinux_check_passwd_access uses getprevcon() for the source and target security contexts.

       checkPasswdAccess is a deprecated alias of the selinux_check_passwd_access function.

RETURN VALUE

       Returns zero on success or -1 on error.
