This patch added a new argument "-C" for the mptcp_join.sh script to set the sysctl checksum_enabled to 1 in ns1 and ns2 to enable the data checksum. In chk_join_nr, check the counter of the mib for the data checksum. Also added a new argument "-S" for the mptcp_join.sh script to start the test cases that verify the checksum handshake: * Sender and listener both have checksums off * Sender and listener both have checksums on * Sender checksums off, listener checksums on * Sender checksums on, listener checksums off The output looks like this: 01 checksum test 0 0 sum[ ok ] - csum [ ok ] 02 checksum test 1 1 sum[ ok ] - csum [ ok ] 03 checksum test 0 1 sum[ ok ] - csum [ ok ] 04 checksum test 1 0 sum[ ok ] - csum [ ok ] 05 no JOIN syn[ ok ] - synack[ ok ] - ack[ ok ] sum[ ok ] - csum [ ok ] 06 single subflow, limited by client syn[ ok ] - synack[ ok ] - ack[ ok ] sum[ ok ] - csum [ ok ] Acked-by: Paolo Abeni <pabeni@redhat.com> Signed-off-by: Geliang Tang <geliangtang@gmail.com> Signed-off-by: Mat Martineau <mathew.j.martineau@linux.intel.com> Signed-off-by: David S.

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.
