Hi
Runing "# ./xdp_iphash_to_cpu --dev eth1 --all-cpus --wan" returns 2 loading errors:
----------------------8<----------------------------------

This program loads the XDP eBPF program into the kernel.

- Attached to device:eth1 (ifindex:4) prog_id:73
----------------------------------8<-------------------------------
Since the XDP program was correctly listed by "bpftool net", I continued an added just ONE ip
# ./xdp_iphash_to_cpu_cmdline --add --ip 1.2.3.4 --classid 1:1234 --cpu 1
key: 0x4030201

iphash_modify() IP:1.2.3.4 key:0x4030201 TC-handle:0x11234
listed the map
# ./xdp_iphash_to_cpu_cmdline --list
{
"1.2.3.4" : { "cpu" : 1, "tc_maj" : "1" , "tc_min" : "1234" }}
And right after I tried to remove the program from XDP:
# ./xdp_iphash_to_cpu --dev eth1 --remove
Removing XDP program on ifindex:4 device:eth1
ERR: Clear ifindex type failed
INFO: not cleanup pinned map file:/sys/fs/bpf/tc/globals/map_ip_hash (use 'rm')
All seems to be rigth despite the errors.
Are all these errors and warnings serious problems? Should I worry?
Hints??

Hi.
Doesn't anybody know how to answer these?

NOTICE above: "Ignored and continue".
Thus, this is not a real *error*, instead this is just a (very) verbose
*warning* that your system (kernel version? / compile options?) doesn't
support BTF correctly. The BTF info is not really needed by
xdp-cpuma-tc, so you can safely ignore this "warning".

This is just a warning you can ignore.
It looks like it works...

What about this one?
"--revove" could not do its job.
None of the three map files were erased.
And not only this one that the error message states.
Won't this cause a memory leak??

Ignoring them.

Thank you for your reply. Ignoring them.
I am running tests at a test environment. Things seem to be Ok.
Just some doubts of a fist time user.

FYI, the error is due to
[7] FUNC xdp_program type_id=5 vlen != 0
I guess you may have an old libbpf. The new libbpf should do
sanitization for this.

Ah, thanks for pointing that out! Guess it is my fault, that I've not
kept git-submodule for libbpf up-to-date in this git-repo.
With the recent interest for xdp-cpumap-tc[1], I will try find some
time to update libbpf and also fix other practical issues that have
been reported to me.
