Title: zfs posix default permissions lost on reboot or unmount Status in linux package in Ubuntu: Fix Released Status in linux source package in Xenial: Fix Committed Status in linux source package in Yakkety: Fix Released Bug description: [SRU Justification][XENIAL] Commit 4967a3e introduced a typo that caused the ZPL to store the intended default ACL as an access ACL. Due to caching this problem may not become visible until the filesystem is remounted or the inode is evicted from the cache. [FIX] https://github.com/zfsonlinux/zfs/commit/98f03691a4c08f38ca4538c468e9523f8e6b24be [TESTCASE] from https://github.com/zfsonlinux/zfs/issues/4520: [root@localhost ~]# cd /mnt/data/ [root@localhost data]# mkdir test_dir [root@localhost data]# setfacl -R --mask -m u:uadm:rwX test_dir/ [root@localhost data]# setfacl -R -d --mask -m u:uadm:rwX test_dir/ [root@localhost data]# getfacl test_dir/ # file: test_dir/ # owner: root # group: root user::rwx user:uadm:rwx group::r-x mask::rwx other::r-x default:user::rwx default:user:uadm:rwx default:group::r-x default:mask::rwx default:other::r-x [root@localhost data]# reboot After a reboot without the fix one gets the following ACLs: [root@localhost ~]# cd /mnt/data/ [root@localhost data]# getfacl test_dir/ # file: test_dir/ # owner: root # group: root user::rwx user:uadm:rwx group::r-x mask::rwx other::r-x With the fix: [root@localhost data]# getfacl test_dir/ # file: test_dir/ # owner: root # group: root user::rwx user:uadm:rwx group::r-x mask::rwx other::r-x default:user::rwx default:user:uadm:rwx default:group::r-x default:mask::rwx default:other::r-x [REGRESSION POTENTAL] Minimal ZFS only and touches just acl setting. This corrects just the ACL_TYPE_DEFAULT case for the ACL setting for ZFS, and sets it to the *correct* name. It is a trivial one line fix. ---------------------------------------------- Ubuntu 16.04 server Problem: Posix default permissions on zfs datasets are lost after rebooting the server or unmounting/remount.
