Mykyta Yatsenko says: ==================== introduce bpf_dynptr_copy kfunc From: Mykyta Yatsenko <yatsenko@meta.com> Introduce a new kfunc, bpf_dynptr_copy, which enables copying of data from one dynptr to another. This functionality may be useful in scenarios such as capturing XDP data to a ring buffer. The patch set is split into 3 patches: 1. Refactor bpf_dynptr_read and bpf_dynptr_write by extracting code into static functions, that allows calling them with no compiler warnings 2. Introduce bpf_dynptr_copy 3. Add tests for bpf_dynptr_copy v2->v3: * Implemented bpf_memcmp in dynptr_success.c test, as __builtin_memcmp was not inlined on GCC-BPF. ==================== Link: https://patch.msgid.link/20250226183201.332713-1-mykyta.yatsenko5@gmail.com Signed-off-by: Andrii Nakryiko <andrii@kernel.org> 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.
