Currently filter table supports only INPUT and OUTPUT chains:
        1) INPUT chain is represented by XDP BPF program
        2) OUTPUT chain is represented by SCHED CLS BPF program

FORWARD chain isn't supported.

Patch 10 adds this test, but then patch 12 removes most of it?
Keep both?

Also hit this on my system with older glibc:

../net/bpfilter/codegen.c: In function ‘codegen_push_subprog’:
../net/bpfilter/codegen.c:67:4: warning: implicit declaration of function ‘reallocarray’ [-Wimplicit-function-declaration]
   67 |    reallocarray(codegen->subprogs, subprogs_max, sizeof(codegen->subprogs[0]));
      |    ^~~~~~~~~~~~
../net/bpfilter/codegen.c:66:12: warning: assignment to ‘struct codegen_subprog_desc **’ from ‘int’ makes pointer from integer without a cast [-Wint-conversion]
   66 |   subprogs =
      |            ^

In libbpf we have libbpf_reallocarray() for this reason.

Could you provide an example of generated bpf program?
And maybe add Documentation/bpf/bpfilter_design.rst ?

The tests don't build for me:
$ cd selftests/bpf/bpfilter; make
make: *** No rule to make target '-lelf', needed by '.../selftests/bpf/bpfilter/test_match'.  Stop.

The unit tests are great, btw. test_codegen is not end-to-end, right?
Could you add a full test with iptable command line?
or netns support is a prerequisite for it?

Sorry, I missed it.
I decided that the large blob looks really ugly and switched to
the smaller one and forgot to cleanup the patchset.

I will add documentation in the next iteration when
bpf_map_for_each() subprog will be introduced.

libelf was added because libbpf depends on it.
Are you able to build libbpf?

Yeah, as net namespaces aren't supported using iptables binary
will modify the root namespace. That is the reason why codegen
tests aren't implemented in the end-to-end fashion and rules are
represented by blobs.

make proceeds to build libbpf just fine, but then it stops with above message.
I manually removed -lelf from Makefile. Then run make to see it fail linking
and then manually copy pasted gcc command to build it with additional -lelf
command line.
fwiw make -v
GNU Make 4.2.1

I think when ifindex is no longer hardcoded the netns support
doesn't have to be gating. The generic xdp attached to veth in netns
should work to do end-to-end test. bpftiler would need to do a bit of magic
to figure out the right ifindex. Or we can extend kernel with ifindex-less
generic XDP.

Is it ok to add an external dependency to tests? The unit test
will need to execute iptables binary.

Ideally not, but sometimes it's unavoidable.
iptables cmd is generally available.
selftests/bpf already have few tests that shell out to it.
They're not part of test_progs though.
