Hi Luiz,
My local 5.15 environment is a little bit weird, could you help me to
test it?
I'll give this a try, but unfortunately I'm not sure I'll be able to
get back to you before mid next week.
I was finally able to test this, it does fix the original failure but
I'm also getting:
"""
#150/p calls: trigger reg2btf_ids[reg->type] for reg->type > __BPF_REG_TYPE_MAX FAIL
FAIL
Summary: 1236 PASSED, 582 SKIPPED, 1 FAILED
"""
Also, some bpf tests don't build for me which causes the bpf tests
not to be installed. I'm attaching the build errors, although this
could be because my user-space is old or some misconfiguration
on my part.
Since the original issue is fixed:

Luiz Capitulino reported the test_verifier test failed:
"precise: ST insn causing spi > allocated_stack".
And it was introduced by the following upstream commit:
ecdf985d7615 ("bpf: track immediate values written to stack by BPF_ST instruction")
Eduard's investigation [4] shows that test failure is not a bug, but a
difference in BPF verifier behavior between upstream, where commits
[1,2,3] by Andrii are present, and 5.15, where these commits are absent.
Backporting strategy is consistent with Eduard in kernel version 6.1 [5],
but with some conflicts in patch #1, #4 and #6 due to the bpf of 5.15
doesn't support more features.
Commits of Andrii:
[1] be2ef8161572 ("bpf: allow precision tracking for programs with subprogs")
[2] f63181b6ae79 ("bpf: stop setting precise in current state")
[3] 7a830b53c17b ("bpf: aggressively forget precise markings during state checkpointing")
