Matthieu Baerts says: ==================== mptcp: pm: special case for c-flag + luminar endp Here are some patches for the MPTCP PM, including some refactoring that I thought it would be best to send at the end of a cycle to avoid conflicts between net and net-next that could last a few weeks. The most interesting changes are in the first and last patch, the rest are patches refactoring the code & tests to validate the modifications. - Patches 1 & 2: When servers set the C-flag in their MP_CAPABLE to tell clients not to create subflows to the initial address and port -- e.g. a deployment behind a L4 load balancer like a typical CDN deployment -- clients will not use their other endpoints when default settings are used. That's because the in-kernel path-manager uses the 'subflow' endpoints to create subflows only to the initial address and port. The first patch fixes that (for >=v5.14), and the second one validates it. - Patches 3-14: various patches refactoring the code around the in-kernel PM (mainly): split too long functions, rename variables and functions to avoid confusions, reduce structure size, and compare IDs instead of IP addresses. Note that one patch modifies one internal variable used in one BPF selftest. - Patch 15: ability to control endpoints that are used in reaction to a new address announced by the other peer. With that, endpoints can be used only once. ==================== Link: https://patch.msgid.link/20250925-net-next-mptcp-c-flag-laminar-v1-0-ad126cc47c6b@kernel.org 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 reStructuredText 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.
