The kernel level documentation on SocketCAN and CAN interfaces is here. This can be used to communicate via the CAN interface through raw sockets in C.
There is a linux package which provides utilities for working with CAN interfaces and messages, can-utils
There look to be two solid Python libraries which provide access to CAN interfaces
There are some other repos on Github dedicated to collecting CAN resources
The Uwindsor P1 page contains some instructions for the P1 and some research papers. There is also P1 documentation
The P1 uses TJA1051 transceivers for CAN and TJA1027 transceivers for LIN/K-Line
