Eric Dumazet says: ==================== tcp: add optional usec resolution to TCP TS As discussed in various public places in 2016, Google adopted usec resolution in RFC 7323 TS values, at Van Jacobson suggestion. Goals were : 1) better observability of delays in networking stacks/fabrics. 2) better disambiguation of events based on TSval/ecr values. 3) building block for congestion control modules needing usec resolution. Back then we implemented a schem based on private SYN options to safely negotiate the feature. For upstream submission, we chose to use a much simpler route attribute because this feature is probably going to be used in private networks. ip route add 10/8 ... features tcp_usec_ts References: https://www.ietf.org/proceedings/97/slides/slides-97-tcpm-tcp-options-for-low-latency-00.pdf https://datatracker.ietf.org/doc/draft-wang-tcpm-low-latency-opt/ First two patches are fixing old minor bugs and might be taken by stable teams (thanks to appropriate Fixes: tags) ==================== Acked-by: Neal Cardwell <ncardwell@google.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.
