Subject: [PATCH bpf-next v4 0/3] Add more bpf_*_ct_lookup() selftests
This patchset adds more bpf_*_ct_lookup() selftests. The goal is to test
interaction with netfilter subsystem as well as reading from `struct
nf_conn`. The first is important when migrating legacy systems towards
bpf. The latter is important in general to take full advantage of
connection tracking.
I'll follow this patchset up with support for writing to `struct nf_conn`.
Past discussion:
- v3: https://lore.kernel.org/bpf/cover.1660173222.git.dxu@dxuuu.xyz/
- v2: https://lore.kernel.org/bpf/cover.1660062725.git.dxu@dxuuu.xyz/
- v1: https://lore.kernel.org/bpf/cover.1659209738.git.dxu@dxuuu.xyz/
Changes since v3:
- Remove deprecated CHECK_FAIL() usage
- cc netfilter folks
Changes since v2:
- Add bpf-ci kconfig changes
Changes since v1:
- Reword commit message / cover letter to not mention connmark writing
