Bug #3249
closed
GenericLinkService performs insufficient validation before calling lp::Packet::get<lp::FragmentField>()
Added by Davide Pesavento over 8 years ago.

Description
ndn::lp::Packet throws exceptions of type std::out_of_range and std::length_error to indicate logic errors.
However, NFD's GenericLinkService::doReceivePacket() performs insufficient validation before calling get<lp::FragmentField>(), which may cause NFD to crash when receiving malformed packets.
Subclasses of std::logic_error thrown by lp::Packet are not packet parsing errors. They are logic errors, and it's intentional that these are not derived from tlv::Error.
GenericLinkService should not allow logic errors to escape to its caller.
Feel free to move this to NFD then.
