This is needed in the context of Tetragon to test cgroup_skb programs using BPF_PROG_TEST_RUN with direct packet access. Commitb39b5f411d("bpf: add cg_skb_is_valid_access for BPF_PROG_TYPE_CGROUP_SKB") added direct packet access for cgroup_skb programs and following commit2cb494a36c("bpf: add tests for direct packet access from CGROUP_SKB") added tests to the verifier to ensure that access to skb fields was possible and also fixed bpf_prog_test_run_skb. However, is_direct_pkt_access was never set to true for this program type, so data pointers were not computed when using prog_test_run, making data_end always equal to zero (data_meta is not accessible for cgroup_skb).

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.
