Local fix
Problem summary
**************************************************************** * USERS AFFECTED: Users of the FTP services diagnose x'2C4' * **************************************************************** * PROBLEM DESCRIPTION: * **************************************************************** * RECOMMENDATION: APPLY PTF * **************************************************************** An LAL008 abend occurs during execution of a guest diagnose x'2C4' instruction due to a dirty high half of a register used to hold the input guest buffer address. The unexpected data caused the translation and locking of the guest buffer to fail and the recovery of that failure to attempt to unlock a guest page that was never locked.
Problem conclusion
The code to translate and lock the input buffer address was updated to ensure the registers used were cleared of any residual data that may have existed before attempting to process the input data buffer.
