`make verify-dns_aaa_records` raise `Exception: Cannot borrow from an ephemeral allocation` #6

Closed tharvik closed 1 year ago

tharvik commented 1 year ago

when trying to verify nf/dns_aaa_records, it raises this weird exception. looking at the readme, its status is "Not verified". shall I also remove it in the coming up PR deleting the paper related files? or is it indeed a bug that should be addressed?

This is not paper-related, it was an extra thing during a semester project from some students, and is indeed not done.

"Ephemeral" here means "allocation that is not supposed to survive an iteration of the packet-processing loop", such as the packet buffer.

"Borrow" means a data structure needs (partial or total) ownership to a chunk of memory, for instance the hash map needs to partially own its keys so that their hashes can't change while they're used by the hash map.

So, do we remove it?

SolalPirelli commented 1 year ago

Yes, like the BPF stuff, we can remove it + add an indication on the readme that it exists at commit xyz.
