Kuniyuki Iwashima says: ==================== Improve bind(addr, 0) behaviour. Currently we fail to bind sockets to ephemeral ports when all of the ports are exhausted even if all sockets have SO_REUSEADDR enabled. In this case, we still have a chance to connect to the different remote hosts. These patches add net.ipv4.ip_autobind_reuse option and fix the behaviour to fully utilize all space of the local (addr, port) tuples. Changes in v5: - Add more description to documents. - Fix sysctl option to use proc_dointvec_minmax. - Remove the Fixes: tag and squash two commits. Changes in v4: - Add net.ipv4.ip_autobind_reuse option to not change the current behaviour. - Modify .gitignore for test. https://lore.kernel.org/netdev/20200308181615.90135-1-kuniyu@amazon.co.jp/ Changes in v3: - Change the title and write more specific description of the 3rd patch. - Add a test in tools/testing/selftests/net/ as the 4th patch. https://lore.kernel.org/netdev/20200229113554.78338-1-kuniyu@amazon.co.jp/ Changes in v2: - Change the description of the 2nd patch ('localhost' -> 'address'). - Correct the description and the if statement of the 3rd patch. https://lore.kernel.org/netdev/20200226074631.67688-1-kuniyu@amazon.co.jp/ v1 with tests: https://lore.kernel.org/netdev/20200220152020.13056-1-kuniyu@amazon.co.jp/ ==================== Reviewed-by: Eric Dumazet <edumazet@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.
