Interesting. I can reproduce with 'test_progs -t snprintf_btf':
5: array name netif_re.rodata flags 0x480
key 4B value 13312B max_entries 1 memlock 20480B
btf_id 5 frozen
10: array name pid_iter.rodata flags 0x480
key 4B value 4B max_entries 1 memlock 8192B
btf_id 10 frozen
pids bpftool(276)
11: array flags 0x0
key 4B value 32B max_entries 1 memlock 4096B
I suppose we do BPF_PROG_BIND_MAP only to #11, so I'm puzzled why
rodata is also leaking.
Will try to take a look!
