ceph: take snap_rwsem when accessing snap realm's cached_context

2015-06-25T08:49:28+00:00

When ceph inode's i_head_snapc is NULL, __ceph_mark_dirty_caps() accesses snap realm's cached_context. So we need take read lock of snap_rwsem. Signed-off-by: Yan, Zheng

ceph: kstrdup() memory handling

2015-04-20T15:55:34+00:00

Currently, there is no check for the kstrdup() for r_path2, r_path1 and snapdir_name as various locations as there is a possibility of failure during memory pressure. Therefore, returning ENOMEM where the checks have been missed. Signed-off-by: Sanidhya Kashyap Signed-off-by: Yan, Zheng

ceph: fix setting empty extended attribute

make sure 'value' is not null. otherwise __ceph_setxattr will remove the extended attribute. Signed-off-by: Yan, Zheng Reviewed-by: Sage Weil

ceph: use pagelist to present MDS request data

2014-10-14T19:56:49+00:00

Current code uses page array to present MDS request data. Pages in the array are allocated/freed by caller of ceph_mdsc_do_request(). If request is interrupted, the pages can be freed while they are still being used by the request message. The fix is use pagelist to present MDS request data. Pagelist is reference counted.

ceph: request xattrs if xattr_version is zero

2014-10-14T17:03:38+00:00

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. Signed-off-by: Yan, Zheng
