linux.git/fs/ceph/file.c, branch v3.18 Linux kernel source tree ceph: include the initial ACL in create/mkdir/mknod MDS requests 2014-10-14T19:56:49+00:00 Yan, Zheng zyan@redhat.com 2014-09-16T12:35:17+00:00 b1ee94aa593abd03634bc3887b8e189840e42c12 Current code set new file/directory's initial ACL in a non-atomic manner. Client first sends request to MDS to create new file/directory, then set the initial ACL after the new file/directory is successfully created. The fix is include the initial ACL in create/mkdir/mknod MDS requests. So MDS can handle creating file/directory and setting the initial ACL in one request.

Current code set new file/directory's initial ACL in a non-atomic
manner.
Client first sends request to MDS to create new file/directory, then set
the initial ACL after the new file/directory is successfully created.

The fix is include the initial ACL in create/mkdir/mknod MDS requests.
So MDS can handle creating file/directory and setting the initial ACL in
one request.

ceph: request xattrs if xattr_version is zero 2014-10-14T17:03:38+00:00 Yan, Zheng zyan@redhat.com 2014-09-16T13:46:17+00:00 508b32d8661b12da4c9ca41a9b2054e1dc92fa7e Following sequence of events can happen. - Client releases an inode, queues cap release message. - A 'lookup' reply brings the same inode back, but the reply doesn't contain xattrs because MDS didn't receive the cap release message and thought client already has up-to-data xattrs. The fix is force sending a getattr request to MDS if xattrs_version is 0. The getattr mask is set to CEPH_STAT_CAP_XATTR, so MDS knows client does not have xattr.
