26 * This module allocates ranges for domains to be used in a
27 * algorithmic mode like idmap_rid. Multiple ranges are supported
28 * for a single domain: If a rid exceeds the range size, a matching
29 * range is allocated to hold the rid's id.
31 * Here are the formulas applied:
34 * For a sid of the form domain_sid-rid, we have
36 * rid = reduced_rid + domain_range_index * range_size
39 * reduced_rid := rid % range_size
40 * domain_range_index := rid / range_size
42 * And reduced_rid fits into a range.
44 * In the database, we associate a range_number to
45 * the pair domain_sid,domain_range_index.
47 * Now the unix id for the given sid calculates as:
49 * id = reduced_rid + range_low_id
53 * range_low_id = low_id + range_number * range_size
56 * The inverse calculation goes like this:
58 * Given a unix id, let
60 * normalized_id := id - low_id
61 * reduced_rid := normalized_id % range_size
62 * range_number = normalized_id / range_size
66 * id = reduced_rid + low_id + range_number * range_size
68 * From the database, get the domain_sid,domain_range_index pair
69 * belonging to the range_number (if there is already one).
71 * Then the rid for the unix id calculates as:
73 * rid = reduced_rid + domain_range_index * range_size
