From 2e532b702834c07f614caf4489feb691e713232a Mon Sep 17 00:00:00 2001 From: Huw Davies Date: Mon, 27 Jun 2016 15:06:17 -0400 Subject: calipso: Add validation of CALIPSO option. Lengths, checksum and the DOI are checked. Checking of the level and categories are left for the socket layer. CRC validation is performed in the calipso module to avoid unconditionally linking crc_ccitt() into ipv6.
