    NAME

    security_compute_av, security_compute_create, security_compute_relabel, security_compute_user - query
    the SE Linux policy database in the kernel.
    

     

    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_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_user(security_context_t scon, const char *username, security_context_t **con);

    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. See the cron source for a usage example.

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

    checkPasswdAccess This functions is a helper functions that allows you to check for a permission in the passwd class. checkPasswdAccess uses getprevcon() for the source and target security contexts.

     

    RETURN VALUE

    0 for success and on error -1 is returned.
