From 894be2d9da60a8e0f7ffc0224e3f294ce49b70be Mon Sep 17 00:00:00 2001 From: Oliver Smith Date: Fri, 11 Jan 2019 13:13:37 +0100 Subject: gsm23003: add osmo_imei_str_valid() Verify 14 digit and 15 digit IMEI strings. OsmoHLR will use the 14 digit version to check IMEIs before writing them to the DB. Place the Luhn checksum code in a dedicated osmo_luhn() function, so it can be used elsewhere.
