CP System PRG006 abend during VM:Account initialization (running with EKG key)


Article ID: 106266


Updated On:




 We have an old process that the operator runs on VMOPER called SETEKG.
It gets run during the first IPL of the systems in the BCP (Disaster Recovery) environment.
The person who wrote it is not longer with the company. It verifies we are doing a test recovery, updated the CALMP KEYS file with the EKG code, then recycles all the products.

The last two months we have tested has resulted in a system abend (PRG006). I processed the dump and it says VMACCT was responsible.
Looking at the log I see it ended and started again, but do not see an init complete.

Provided new PTF SO04402 to correct this CP ABEND. This PTF is marked as HYPER due to the potential for a CP SYSTEM ABEND.
The problem is with VM:Secure and not VM:Account therefore, the PTF needs to be applied to VM:Secure.

The root cause of the problem is the same as what you experienced with the "AT" command, where having a "CPACTION userid ACCEPT" without the NOPASS option ends up with VM:Secure going down the code path to verify the entered password for commands that do not rely on a password for authorization (the password is never obtained or otherwise prompted for).
When the NOPASS option is included, the password verification logic is correctly bypassed for these commands.
This problem has always existed in the code, but it coincidentally never caused a problem because the length of the stored password in the directory was always 8 bytes or less (if you were running with Password Phrases AND encryption that would expose the problem also).

We have also verified we now account for all the commands and situations that go through this ACI "LOGON logic".

This PTF is an update to the CP components, so after you have applied and deployed the PTF, you must run VMXCPG to regenerate the updated CP TEXT file replacements, reinstall the LOCALMODs, and regenerate a new CP nucleus.
