Mat Martineau says: ==================== mptcp: Fixes for ULP, a deadlock, and netlink docs Two of the MPTCP fixes in this set are related to the TCP_ULP socket option with MPTCP sockets operating in "fallback" mode (the connection has reverted to regular TCP). The other issues are an observed deadlock and missing parameter documentation in the MPTCP netlink API. Patch 1 marks TCP_ULP as unsupported earlier in MPTCP setsockopt code, so the fallback code path in the MPTCP layer does not pass the TCP_ULP option down to the subflow TCP socket. Patch 2 makes sure a TCP fallback socket returned to userspace by accept()ing on a MPTCP listening socket does not allow use of the "mptcp" TCP_ULP type. That ULP is intended only for use by in-kernel MPTCP subflows. Patch 3 fixes the possible deadlock when sending data and there are socket option changes to sync to the subflows. Patch 4 makes sure all MPTCP netlink event parameters are documented in the MPTCP uapi header. ==================== Link: https://lore.kernel.org/r/20211214231604.211016-1-mathew.j.martineau@linux.intel.com Signed-off-by: Jakub Kicinski <kuba@kernel.org> |

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.
