Introducing bpf_dynptr_copy kfunc allowing copying data from one dynptr to another. This functionality is useful in scenarios such as capturing XDP data to a ring buffer. The implementation consists of 4 branches: * A fast branch for contiguous buffer capacity in both source and destination dynptrs * 3 branches utilizing __bpf_dynptr_read and __bpf_dynptr_write to copy data to/from non-contiguous buffer Signed-off-by: Mykyta Yatsenko <yatsenko@meta.com> Signed-off-by: Andrii Nakryiko <andrii@kernel.org> Link: https://lore.kernel.org/bpf/20250226183201.332713-3-mykyta.yatsenko5@gmail.com Signed-off-by: Alexei Starovoitov <ast@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.
