Vadim Fedorenko says: ==================== This series introduces crypto kfuncs to make BPF programs able to utilize kernel crypto subsystem. Crypto operations made pluggable to avoid extensive growth of kernel when it's not needed. Only skcipher is added within this series, but it can be easily extended to other types of operations. No hardware offload supported as it needs sleepable context which is not available for TX or XDP programs. At the same time crypto context initialization kfunc can only run in sleepable context, that's why it should be run separately and store the result in the map. Selftests show the common way to implement crypto actions in BPF programs. Benchmark is also added to have a baseline. ==================== Signed-off-by: Martin KaFai Lau <martin.lau@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.
