Thanks for pointing out the third validator. I have included the LPM trie case in v2. The struct key is not a reason to leave it out: the updated check validates the /32 prefix and complete 192.168.1.x address, then checks the host octet against the inserted key range before using it to index visited.
I also moved the validation notes below the --- separator, leaving the commit message focused on the problem and the fix. The revised full test_maps suite passes with no skips on the matching kernel, including array, per-CPU array, hash, per-CPU hash and LPM batch tests. The revised patch is here: https://lore.kernel.org/bpf/[email protected]/ Thanks, Tianyi
