libafl multimachine: disable ratelimiting #2558

Closed rmalmain closed 1 month ago

rmalmain commented 1 month ago

originally there was a (primitive) rate limiter in case a lot of testcases were received by a node at once. this caused the buffer to not be emptied fast enough on some targets when inputs are heavy. i will refactor rate limiting if it happens to be necessary later on, for now it should not cause any problem to disable it.

The rate limiting should be on the sender side, IMHO

hum not sure about this, a child doesn't know how many other children there are for a given parent, so it cannot (apriori) know what rate limit to choose statically. i think it would only work if the parent dynamically gives a rate limit to each child, but it would require much more extensive modifications of the current implem.

just a global setting "don't send more often than every x millis" is fine
