tests: call.strcontains fails constantly on Linux v6.10 about bpftrace

[ajor]

Thanks for the report @piso77. I can't reproduce it on my kernel, so would you be able to share the output of your verifier logs to help us debug it please?

You should (hopefully) be able to get it with this command:

# bpftrace -e 'kfunc:filp_close { $f = path(args.filp->f_path); if (strcontains($f, "tmp")) { printf("OK\n"); exit(); } }' -d verifier

$ sudo ./src/bpftrace -v -e 'kfunc:filp_close { $f = path(args.filp->f_path); if (strcontains($f, "tmp")) { printf("OK\n"); exit(); } }' -d verifier

Here is the .config i've used to build the above kernel.

@piso77 based on the log, it looks to me that you don't have a sufficiently new libbpf installed. Since #3285, we require libbpf which includes libbpf/libbpf@dd589c3.
