The latter means that any subsequent system -call against that open file fail until a share is re-mounted. - -Fix this by properly setting SMB create options when -re-openning files after reconnects. - -Fixes: 1013e760d10e6: ("SMB3: Don't ignore O_SYNC/O_DSYNC and O_DIRECT flags") -Cc: Stable <stable@vger.kernel.org> -Signed-off-by: Pavel Shilovsky <pshilov@microsoft.com> -Signed-off-by: Steve French <stfrench@microsoft.com> -Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> - ---- - fs/cifs/file.c | 7 +++++++ - 1 file changed, 7 insertions(+) - ---- a/fs/cifs/file.c -+++ b/fs/cifs/file.c -@@ -696,6 +696,13 @@ cifs_reopen_file(struct cifsFileInfo *cf - if (backup_cred(cifs_sb)) - create_options |= CREATE_OPEN_BACKUP_INTENT; - -+ /* O_SYNC also has bit for O_DSYNC so following check picks up either */ -+ if (cfile->f_flags & O_SYNC) -+ create_options |= CREATE_WRITE_THROUGH; -+ -+ if (cfile->f_flags & O_DIRECT) -+ create_options |= CREATE_NO_BUFFER; -+ - if (server->ops->get_lease_key) - server->ops->get_lease_key(inode, &cfile->fid); - |
