If the client interface is down, or there is a network partition between the client and server that prevents the callback request to reach the client, TCP on the server will keep re-transmitting the callback for about ~9 minutes before giving up and closing the connection. If the connection between the client and the server is re-established before the connection is closed and after the callback timed out (9 secs) then the re-transmitted callback request will arrive at the client. When the server receives the reply of the callback, receive_cb_reply prints the "Got unrecognized reply..." message in the system log since the callback request was already removed from the server xprt's recv_queue. Even though this scenario has no effect on the server operation, a malfunctioning or malicious client can fill up the server's system log.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
