validate p2p messages and topics #1755

onur-ozkan · 2023-04-13T13:04:37Z

Applies the following checks:

Validate topics if they are mixed or not.
Do early return if the message data is not valid (since no point to iterate over and over on the invalid message)
~~Avoid decoding messages that have more than 25 topics~~
Break the loop right after processing any of SWAP_PREFIX, WATCHER_PREFIX, TX_HELPER_PREFIX topic.

Thanks for this fix!
Just a note for the first view and question: Why did you choose 25 topics limit?

Why did you choose 25 topics limit?

25 topics can't hurt, and it's quite flexible value for any case I think.

It would be more clear it did not stick up, explained before

Can you clarify this, didn't understand it

Now it can be rolled back because stick up logic has been hidden

Could you document(either here in the PR comments or in the changelog) why you are changing this value?

Because HTLCs requiring more gas than our limit lately. Since gas prices can be updated from the coins configuration, this should never be problem even if we make it 200_000.

Does it require to drop mutability explicitly?

drop_mutability! is done to ensure that the order cannot be accidentally modified later in this part of the code.
