From 671137d5cda4a7415b34246bd8842650a7c6ddd9 Mon Sep 17 00:00:00 2001 From: Michael Jeanson Date: Tue, 9 Jan 2018 15:43:19 -0500 Subject: [PATCH] Fix: debian kernel version parsing The debian version script only worked for ckt kernels and that was fine until now because we only had checks for those versions in the code. ckt (Canonical Kernel Team) kernels were used for a while during the jessie cycle, their versionning is a bit different. They track the upstream vanilla stable updates but they don't update the minor version number and instead add an additionnal -cktX. They were all 3.16.7-cktX and after a while the version switched back to upstream style at 3.16.36. Knowing that, we can compare regular debian and ckt kernel versions using this scheme : MAJOR.PATCHLEVEL.SUBLEVEL.CKT.DEBABI.DEBPATCH And setting CKT to zero for non-ckt kernels.
