====================
This patch set makes bpf_sk_lookup_tcp, bpf_sk_lookup_udp and
bpf_sk_release helpers available in programs of type
BPF_PROG_TYPE_CGROUP_SOCK_ADDR.
Patch 1 is a fix for bpf_sk_lookup_udp that was already merged to bpf
(stable) tree. Here it's prerequisite for patch 3.
Patch 2 is the main patch in the set, it makes the helpers available for
BPF_PROG_TYPE_CGROUP_SOCK_ADDR and provides more details about use-case.
Patch 3 adds selftest for new functionality.
v1->v2:
- remove "Split bpf_sk_lookup" patch since it was already split by:
commit c8123ead13 ("bpf: Extend the sk_lookup() helper to XDP
hookpoint.");
- avoid unnecessary bpf_sock_addr_sk_lookup function.

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 Restructured Text 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.
