ceph: fix file lock interruption

2014-12-17T17:09:49Z

When a lock operation is interrupted, current code sends a unlock request to MDS to undo the lock operation. This method does not work as expected because the unlock request can drop locks that have already been acquired. The fix is use the newly introduced CEPH_LOCK_FCNTL_INTR/CEPH_LOCK_FLOCK_INTR requests to interrupt blocked file lock request. These requests do not drop locks that have alread been acquired, they only interrupt blocked file lock request. Signed-off-by: Yan, Zheng

ceph: update inode fields according to issued caps

2014-06-06T01:29:52Z

Cap message and request reply from non-auth MDS may carry stale information (corresponding locks are in LOCK states) even they have the newest inode version. So client should update inode fields according to issued caps. Signed-off-by: Yan, Zheng

ceph: use fl->fl_file as owner identifier of flock and posix lock

2014-04-05T04:07:11Z

flock and posix lock should use fl->fl_file instead of process ID as owner identifier. (posix lock uses fl->fl_owner. fl->fl_owner is usually equal to fl->fl_file, but it also can be a customized value). The process ID of who holds the lock is just for F_GETLK fcntl(2). The fix is rename the 'pid' fields of struct ceph_mds_request_args and struct ceph_filelock to 'owner', rename 'pid_namespace' fields to 'pid'. Assign fl->fl_file to the 'owner' field of lock messages. We also set the most significant bit of the 'owner' field. MDS can use that bit to distinguish between old and new clients. The MDS counterpart of this patch modifies the flock code to not take the 'pid_namespace' into consideration when checking conflict locks. Signed-off-by: Yan, Zheng Reviewed-by: Sage Weil

ceph: remove xattr when null value is given to setxattr()

For the setxattr request, introduce a new flag CEPH_XATTR_REMOVE to distinguish null value case from the zero-length value case. Signed-off-by: Yan, Zheng
