** Description changed: + [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.
