OpenVMS VMS721H1_LIBRTL-V0100 Alpha V7.2-1H1 RTL ECO Summary

TITLE: OpenVMS VMS721H1_LIBRTL-V0100 Alpha V7.2-1H1 RTL ECO Summary Modification Date: 22-NOV-2000 Modification Type: New Kit NOTE: An OpenVMS saveset or PCSI installation file is stored on the Internet in a self-expanding compressed file. For OpenVMS savesets, the name of the compressed saveset file will be kit_name.a-dcx_vaxexe for OpenVMS VAX or kit_name.a-dcx_axpexe for OpenVMS Alpha. Once the OpenVMS saveset is copied to your system, expand the compressed saveset by typing RUN kitname.dcx_vaxexe or kitname.dcx_alpexe. For PCSI files, once the PCSI file is copied to your system, rename the PCSI file to kitname-dcx_axpexe.pcsi, then it can be expanded by typing RUN kitname-dcx_axpexe.pcsi. The resultant file will be the PCSI installation file which can be used to install the ECO. Copyright (c) Compaq Computer Corporation 2000. All rights reserved. OP/SYS: OpenVMS Alpha COMPONENT: LIBRTL SOURCE: Compaq Computer Corporation ECO INFORMATION: ECO Kit Name: VMS721H1_LIBRTL-V0100 DEC-AXPVMS-VMS721H1_LIBRTL-V0100--4.PCSI ECO Kits Superseded by This ECO Kit: None ECO Kit Approximate Size: 4304 Blocks Kit Applies To: OpenVMS Alpha V7.2-1H1 System/Cluster Reboot Necessary: Yes Rolling Re-boot Supported: Yes Installation Rating: INSTALL_3 3 - To be installed on all systems running the listed versions of OpenVMS which are experiencing the problems described. Kit Dependencies: The following remedial kit(s) must be installed BEFORE installation of this kit: VMS721H1_UPDATE-V0300 In order to receive all the corrections listed in this kit, the following remedial kits should also be installed: None ECO KIT SUMMARY: An ECO kit exists for RTL on OpenVMS Alpha V7.2-1H1. This kit addresses the following problems: o A memory leak occurs when using LIB$FIND_FILE/LIB$FIND_FILE_END with long file names (flags=LIB$M_FIL_LONG_NAMES). Images Affected: [SYSLIB]LIBRTL.EXE [SYSLIB]LIBRTL_INSTRUMENTED.EXE o A synchonization failure occurs for multithread programs using the DEC C RTL routine malloc and free with "long" pointers (P2 space heap routines). These DEC C RTL routines in turn use the LIBRTL Routines LIB$VM_MALLOC_64 and LIB$VM_FREE_64. Symptoms could be varied, including "%LIB-F-MEMALRFRE, memory already free" errors. For an application to see this problem it would have to have the following characteristics: 1. Call the DEC C RTL routines malloc and free 2. Be multithreaded 3. Be compiled with the /POINTER_SIZE=LONG and /REENTRANCY=MULTITHREAD switches 4. Be linked /THREADS_ENABLE=(MULTIPLE_KERNEL_THREADS,UPCALLS) 5. Run on a multiprocessor system with kernel threads enabled. Note that programs using the "normal" P0 heap routines are not affected by this problem. Images Affected: [SYSLIB]LIBRTL.EXE [SYSLIB]LIBRTL_INSTRUMENTED.EXE o The LIB$CREATE_DIR RTL routine is documented to accept 64 bit parameters. However, passing a 64 bit descriptor to the routine fails with a LIB$_INVSTRDES error or passing a 64 bit address may result in an SS$_ACCVIO error. Images Affected: [SYSLIB]LIBRTL.EXE [SYSLIB]LIBRTL_INSTRUMENTED.EXE o A program can fail with the following error: %LIB-W-ILLRECTYP, illegal record type (nnn) %TRACE-W-TRACEBACK, symbolic stack dump follows followed by: %SYSTEM-F-ACCVIO, access violation, reason mask=00, virtual address=0000000000000008, PC=nnnnnnnnnnnnnnnn, PS=0000001B if the program: 1. Is created that is directly linked with a shareable image 2. Calls LIB$FIND_IMAGE_SYMBOL to find an entry point in the same shareable image 3. The program is executed and the user creates a new version of the shareable image while the program is executing Images Affected: [SYSLIB]LIBRTL.EXE [SYSLIB]LIBRTL_INSTRUMENTED.EXE o LIB$FIND_IMAGE_SYMBOL fails to locate symbols for images whose record attributes have been altered. This has been seen with DCOM as follows: $ mcr DCOM$COMREGEDT %SYSTEM-F-ACCVIO, access violation, reason mask=00, virtual address=0000000000000008, PC=0000000000B43348, PS=0000001B Improperly handled condition, image exit forced. Signal arguments: Number = 0000000000000005 Name = 000000000000000C 0000000000000000 0000000000000008 0000000000B43348 000000000000001B Images Affected: [SYSLIB]LIBRTL.EXE [SYSLIB]LIBRTL_INSTRUMENTED.EXE o LIB$FIND_IMAGE_SYMBOL fails for images on disks whose device names are more than 13 characters - which generally means a 3 digit unit number. Images Affected: [SYSLIB]LIBRTL.EXE [SYSLIB]LIBRTL_INSTRUMENTED.EXE o In the case of a $ PRINT [X]FOO.PRF,;-1 command, LIB$FIND_FILE may fail to find the second file (;-1). This problem may be seen with certain DCL commands, such as PRINT, and with user application calls to LIB$FIND FILE when LIB$M_FIL_LONG_NAMES and the "multiple" flags are set (bits 1 and 2 of the flags argument). Images Affected: [SYSLIB]LIBRTL.EXE [SYSLIB]LIBRTL_INSTRUMENTED.EXE o A failure to unwind properly occurs when a large amount of stack space is being used. This could result in an improperly handled condition error, or a bad stack notification, or other error. Images Affected: [SYSLIB]LIBRTL.EXE [SYSLIB]LIBRTL_INSTRUMENTED.EXE INSTALLATION NOTES: The images in this kit will not take effect until the system is rebooted. If there are other nodes in the VMScluster, 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. Install this kit with the POLYCENTER Software installation utility by logging into the SYSTEM account, and typing the following at the DCL prompt: PRODUCT INSTALL VMS721H1_LIBRTL /SOURCE=[location of Kit] The kit location may be a tape drive, CD, or a disk directory that contains the kit. Additional help on installing PCSI kits can be found by typing HELP PRODUCT INSTALL at the system prompt All trademarks are the property of their respective owners.
