+Subject: [PATCH] ecryptfs-utils: CVE-2016-6224
+
+src/utils/ecryptfs-setup-swap: Prevent unencrypted swap partitions from
+being automatically enabled by systemd. This bug affected GPT partitioned
+NVMe/MMC drives and resulted in the swap partition being used without
+encryption. It also resulted in a usability issue in that users were
+erroneously prompted to enter a pass-phrase to unlock their swap partition
+at boot. (LP: #1597154)
+
+the patch comes from:
