DESCRIPTION

41       get_ordered_context_list()  invokes  the security_compute_user(3) func‐
42       tion to obtain the list of contexts for the  specified  user  that  are
43       reachable from the specified fromcon context.  The function then orders
44       the      resulting      list      based       on       the       global
45       /etc/selinux/{SELINUXTYPE}/contexts/default_contexts  file and the per-
46       user /etc/selinux/{SELINUXTYPE}/contexts/users/<username>  file  if  it
47       exists.  The fromcon parameter may be NULL to indicate that the current
48       context should be used.  The function returns the number of contexts in
49       the  list,  or  -1  upon  errors.   The  list  must  be freed using the
50       freeconary(3) function.
51
52       get_ordered_context_list_with_level()            invokes            the
53       get_ordered_context_list() function and applies the specified level.
54
55       get_default_context()  is  the  same  as get_ordered_context_list() but
56       only returns a single context which has to be freed with freecon(3).
57
58       get_default_context_with_level()  invokes   the   get_default_context()
59       function and applies the specified level.
60
61       get_default_context_with_role()  is  the  same as get_default_context()
62       but only returns a context with the specified role, returning -1 if  no
63       such context is reachable for the user.
64
65       get_default_context_with_rolelevel()             invokes            the
66       get_default_context_with_role()  function  and  applies  the  specified
67       level.
68
69       query_user_context()  takes  a  list  of contexts, queries the user via
70       stdin/stdout as to which context they want, and returns a  new  context
71       as selected by the user (which has to be freed with freecon(3)).
72
73       manual_user_enter_context() allows the user to manually enter a context
74       as a fallback if a list of authorized contexts could not  be  obtained.
75       Caller must free via freecon(3).
76
77       get_default_type()  Get the default type (domain) for role and set type
78       to refer to it, which has to be freed with free.

RETURN VALUE

81       get_ordered_context_list()  and   get_ordered_context_list_with_level()
82       return  the  number  of  contexts  in  the list upon success or -1 upon
83       errors.  The other functions return 0 for success or -1 for errors.
