Log:
MFP4 (108673, 110519, 110874):
- Currently LINUX_MAX_COMM_LEN is smaller than MAXCOMLEN, but in case
this will change we have a buffer overflow. Apply some defensive
programming to DTRT when this should happen.
- Use copyinstr() instead of copyin where appropriate.
* Fallback to copyin() in case of ENAMETOOLONG. [1]
* Use the right source and destination (it was wrong before).
- Use strlcpy instead of strcpy.
- Properly lock the read case (PR_GET_NAME) like the write case.
