Create a netconsole test that puts a lot of pressure on the netconsole list manipulation. Do it by creating dynamic targets and deleting targets while messages are being sent. Also put interface down while the messages are being sent, as creating parallel targets. The code launches three background jobs on distinct schedules: * Toggle netcons target every 30 iterations * create and delete random_target every 50 iterations * toggle iface every 70 iterations This creates multiple concurrency sources that interact with netconsole states. This is good practice to simulate stress, and exercise netpoll and netconsole locks. This test already found an issue as reported in [1] Link: https://lore.kernel.org/all/20250901-netpoll_memleak-v1-1-34a181977dfc@debian.org/ [1] Signed-off-by: Breno Leitao <leitao@debian.org> Reviewed-by: Andre Carvalho <asantostc@gmail.com> Reviewed-by: Simon Horman <horms@kernel.org> Link: https://patch.msgid.link/20251107-netconsole_torture-v10-3-749227b55f63@debian.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.
