setfacl removes part of ACL when setting POSIX ACLs to Samba
commit b1d93356427be6f050dc55c86eb019d173700af6 upstream.
setfacl over cifs mounts can remove the default ACL when setting the
(non-default part of) the ACL and vice versa (we were leaving at 0
rather than setting to -1 the count field for the unaffected
half of the ACL. For example notice the setfacl removed
the default ACL in this sequence:
steven@steven-GA-970A-DS3:~/cifs-2.6$ getfacl /mnt/test-dir ; setfacl
-m default:user:test:rwx,user:test:rwx /mnt/test-dir
getfacl: Removing leading '/' from absolute path names
user::rwx
group::r-x
other::r-x
default:user::rwx
default:user:test:rwx
default:group::r-x
default:mask::rwx
default:other::r-x
