From 8d2dcb41f4b7acbb1dac92107ee3c086221f06ae Mon Sep 17 00:00:00 2001 From: "Robin H. Johnson" Date: Wed, 15 May 2019 21:50:51 -0700 Subject: sys-auth/pam_mount: fix LUKS2 header detection for AEAD/integrity Trying to use a LUKS2 device via pam_mount fails with a cryptic message: 'No dmcrypt cipher specified (use -o cipher=xxx)' Trivial upstream patch is needed to fix the detection.
