The SYN flood message prints the listening port number, but with many processes bound to the same port on different IPs, it's impossible to tell which socket is the problem. Add the listen IP address to the SYN flood message. For IPv6 use "[IP]:port" as per RFC-5952 and to provide ease of copy-paste to "ss" filters. For IPv4 use "IP:port" to match. Each protcol's "any" address and a host address now look like: Possible SYN flooding on port 0.0.0.0:9001. Possible SYN flooding on port 127.0.0.1:9001. Possible SYN flooding on port [::]:9001. Possible SYN flooding on port [fc00::1]:9001.

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.
