ECO NUMBER: VAXF11X02_073 PRODUCT: OpenVMS VAX OPERATING SYSTEM V7.3 UPDATE PRODUCT: OpenVMS VAX OPERATING SYSTEM V7.3 COVER LETTER 1 KIT NAME: VAXF11X02_073 2 KITS SUPERSEDED BY THIS KIT: VAXF11X01_073 3 KIT DEPENDENCIES: 3.1 The following remedial kit(s), or later, must be installed BEFORE installation of this, or any required kit: None. 3.2 In order to receive all the corrections listed in this kit, the following remedial kits, or later, should also be installed: None. 4 KIT DESCRIPTION: 4.1 Version(s) of OpenVMS to which this kit may be applied: OpenVMS VAX V7.3 4.2 Files patched or replaced: o [SYS$LDR]F11BXQP.EXE (new image) o [SYSEXE]F11CACP.EXE (new image) o [SYSEXE]F11DACP.EXE (new image) 5 PROBLEMS ADDRESSED IN VAXF11X02_073 KIT o The VAXF11X01_073 ECO kit was missing an installation file which prevented the kit from installing. -- COVER LETTER -- Page 2 12 September 2002 6 PROBLEMS ADDRESSED IN VAXF11X01_073 KIT o If multiple processes on the same node are attempting to obtain or convert the same lock, which is being mastered on another node, it is possible to get an SS$_CVTUNGRANT error in addition to an SS$_IVLOCKID error during this race. The problem arises because the new, faster lock manager, adds timing considerations that were not previously present. The code now traps this error and retries the lock conversion attempt. Images Affected: - [SYS$LDR]F11BXQP.EXE o A system can crash with a MAPCNTZER bugcheck, in XQP routine MAKE_POINTER, when trying to expand or create a new PAGEFILE.SYS. Crash Dump Summary Information: ------------------------------ Bugcheck Type: MAPCNTZER, Attempted to generate zero length map pointer Current Image: DSA0:[SYS0.SYSCOMMON.][SYSEXE]SYSGEN.EXE Failing PC: FFFFFFFF.A89F6B98 MAKE_POINTER_C+00044 Failing PS: 30000000.00000000 Module: F11BXQP (Link Date/Time: 24-AUG-2000 07:20:45.47) Offset: 00026B98 This problem occurs in the XQP only on volumes where the cluster size exceeds 256 and the volume is so fragmented that the file in question would need to expand beyond the first file header. The fix for this problem will result in a SS$_HEADERFULL error for SYSGEN CREATE instead the bugcheck encountered. Images Affected: - [SYS$LDR]F11BXQP.EXE o The system can crash with a UNXSIGNAL bugcheck in routine ACL_BUILDACL. The exception occurs because the XQP tries to access a null FCB (which was loaded from a previous FCB that had FCB$L_EXFCB = 0). Crash Dump Summary ------------------ Bugcheck Type: UNXSIGNAL, Unexpected signal name in ACP Current Process: BATCH_488 Failing PS: 20000000.00000000 Module: F11BXQP (Link Date/Time: 24-AUG-2000 07:20:45.47) Offset: 00052DC4 -- COVER LETTER -- Page 3 12 September 2002 Images Affected: - [SYS$LDR]F11BXQP.EXE o When using SYS$CHECK_ACCESS against a file that resides on a CD-ROM the process disappears and the accounting record shows a final status of ACCVIO. If BUGCHECK_FATAL or SYSTEM_CHECK are set, the system bugchecks with SSRVEXCEPT in SYS$$CHECK_ACCESS. The same program, when used against a file that is not on a CD-ROM, works as expected. The problem occurs because SYS$$CHECK_ACCESS calls FIL$OSR_CLONE_PROFILE. FIL$OSR_CLONE_PROFILE does a $QIO against the file for IO$_ACPCONTROL, with a FIB control function of FIB$C_CLONE_FIL_PROFILE. This $QIO returns good status even though this control function is not implemented in ACPCONTROL.B32. So, routine FIL$OSR_CLONE_PROFILE returns SS$_NORMAL and the returned ORB is null (which leads to the exception). Also, it was found that the embedded ORB associated with the file (FCB) was not being initialized in the case of an XAR not being supplied. Images Affected: - [SYSEXE]F11CACP.EXE - [SYSEXE]F11DACP.EXE o SYS$CHECK_ACCESS uses the FIB option FIB$V_NO_READ_DATA to read the ACL/protection attributes of a file object. When the file is opened with read sharing dis-allowed, this service returns SS$_ACCONFLICT. If the service adds the FIB$V_CONTROL flag, this does not occur. The problem occurs because the code presumes that for access to a file open for exclusive access would require the user specify control access. The security group decided that this was not needed so the use of CONTROL was removed. The use of FIB$V_NOLOCK, which also allows this, still requires SYSPRV if the file data is to be read. This change relaxes the requirement for specifying FIB$V_CONTROL, which implies the need for write access to the file. This is not the case and FIB$V_NO_READ_DATA prevents the file system from mapping the data in the file.

(Reference attached Disclaimer of Warranty and Limitation of Liability Statement) INSTALLATION RATING: INSTALL_1 : To be installed by all customers. 8 INSTALLATION INSTRUCTIONS: Install this kit with the VMSINSTAL utility by logging into the SYSTEM account, and typing the following at the DCL prompt: @SYS$UPDATE:VMSINSTAL VAXF11X02_073 [location of the saveset] The saveset location may be a tape drive, CD, or a disk directory that contains the kit saveset. This kit requires a system reboot. Compaq strongly recommends that a reboot is performed immediately after kit installation to avoid system instability If you have other nodes in your OpenVMS cluster, they must also be rebooted in order to make use of the new image(s). If it is not possible or convenient to reboot the entire cluster at this time, a rolling re-boot may be performed. Copyright (c) Compaq Computer Company, 2002 All Rights Reserved.
