When the NFS server does Setxattr or Removexattr, the operations must be done IO_SYNC. If a server crashes/reboots immediately after replying it must have the extended attribute changes. Since UFS does extended attributes asynchronously by default and there is no "ioflag" argument in the VOP calls, follow the VOP calls with VOP_FSYNC(), to ensure the operation has been done synchronously. This was found by inspection while investigating a bug discovered during a recent IETF NFSv4 testing event, where the Change attribute wasn't changed in the operation reply. This bug will take further work for ZFS and the pNFS server configuration, but is now fixed for a non-pNFS UFS exported file system. MFC after: 1 month |
