Thanks for diagnosing this! Can you add a link to the upstream commit in the commit message? You'll also have to update the kernel versions we test against in CI. |

In kernel v6.8, logic was added that restricts valid func info BTF for programs that can be replaced with an BPF_PROG_TYPE_EXT program. Before this change the parameters of the extension program had to be the same as the original program. Commit torvalds/linux@5eccd2db42d77e357 made it so the verifier asserts that the BTF func info of "main" programs must have exactly 1 parameter of a pointer type to the context struct, even if the code doesn't use the context like in our case.

Kernel 6.8 is currently the latest stable kernel release, so test against it. Also add 6.6 to the test matrix since it is an LTS release. Signed-off-by: Dylan Reimerink <dylan.reimerink@isovalent.com>

This PR updates the kernels we test against in CI to the latest stable kernel, v6.8. However, the feature probe for the extension program type fails on this kernel, so we also include a fix to the probe.
In kernel v6.8, logic was added that restricts valid func info BTF for programs that can be replaced with an BPF_PROG_TYPE_EXT program. Before this change the parameters of the extension program had to be the same as the original program. However, now the verifier asserts that the BTF func info of "main" programs must have exactly 1 parameter of a pointer type to the context struct, even if the code doesn't use the context like in our case.
