Narrative:

Flying back from honolulu I was authorized to enter the class bravo airspace at honolulu and I requested vectors to [the] runway. Given vectors and an altitude of 2;000 feet until 5 DME I was then handed off to tower and given clearance to land. No other restrictions were given. Upon being cleared to land; I did. And I went from where I was to where the runway was by the safest and most expeditious manner.ATC failed to give further restrictions and further failed to inform me of the airspace they vectored me into; I noticed on my GPS that I was going to cut the outer edge of kalaeloa airport's airspace; as it has a ceiling of 2;000 feet. But given a new clearance; one to land and not given any other restrictions; I began my descent and landed uneventfully.while taxing to park I was given a phone number to call. It was the honolulu tracon telling me I had violated kalaeloa's airspace by descending after I was cleared to land. I was aware of the airspace but as I stated; when switched to tower I was cleared to land with no further instructions to maintain 2;000 feet. I therefore entered the landing phase of the flight thinking I had complied with each controllers instructions.
