DEC TCP/IP UCXALP_E04042 DIGITAL TCP/IP V4.2 ECO Summary

TITLE: DEC TCP/IP UCXALP_E04042 DIGITAL TCP/IP V4.2 ECO Summary Modification Date: 21-DEC-2000 Modification Type: Documentation: Technical Removed references to OpenVMS V7.2. TCP/IP V4.2 is not supported on OpenVMS V7.2. 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 1999, 2000. All rights reserved. PRODUCT: DIGITAL TCP/IP Services for OpenVMS V4.2 OP/SYS: OpenVMS Alpha SOURCE: Compaq Computer Corporation ECO INFORMATION: ECO Kit Name: UCXALP_E04042 DEC-AXPVMS-UCXECO_42_4-V0200--4.PCSI ECO Kits Superseded by This ECO Kit: UCXALP_E03042 DEC-AXPVMS-UCXECO_42_3-V0200--4.PCSI UCXALP_E02042 DEC-AXPVMS-UCXECO_42_2-V0100--4.PCSI UCXALP_E01042 DEC-AXPVMS-UCXECO_42_1-V0100--4.PCSI ECO Kit Approximate Size: 32,544 Blocks Kit Applies To: Digital TCP/IP Services for OpenVMS V4.2 OpenVMS Alpha V6.2; V7.1 System/Cluster Reboot Necessary: Yes Rolling Re-boot Supported: Not Known Installation Rating: INSTALL_UNKNOWN Kit Dependencies: The following remedial kit(s) must be installed BEFORE installation of this kit: None 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 TCP/IP V4.2 on OpenVMS Alpha V6.2 & V7.1. The following sections describe the corrections to each facility. ------------------------------------------------------------------------------- PREVIOUSLY UNDOCUMENTED BEHAVIOR: ------------------------------------------------------------------------------- --------------------------------------------------------------- 1: PTR 70-5-1032 User buffer length problem --------------------------------------------------------------- Note: Because of the following ECO to UCX V4.1, which was incorporated into the UCX V4.2 base release, user buffer lengths are now validated and rejected if they exceed 64K: ECO Y 2-Apr-1997 Alpha and VAX Images: UCX$BGDRIVER.EXE UCX V4.1-12Y UCX$INTERNET_SERVICES.EXE UCX V4.1-12Y (VAX) UCX$INTERNET_SERVICES_V6.EXE UCX V4.1-12Y (VAX) UCX$INTERNET_SERVICES_SEC.EXE UCX V4.1-12Y (VAX) UCX$INTERNET_SERVICES_SEC_V6.EXE UCX V4.1-12Y (VAX) UCX$INETACP.EXE UCX V4.1-12Y Problem: System crash on write to a BG device when P2 parameter (user buffer length) specifies a negative value. Solution: Lengths of user buffers were not being properly validated and as a result, the negative value length was being misinterpreted as a large positive number. The fix is to properly validate this length, limiting lengths to 64KB-1 bytes. Lengths greater than this and lengths less than zero will now cause the I/O request to be terminated with an SS$_IVBUFLEN status. Reference: See the diagram on p. 3-4 of the "UCX System Services and C Socket Programming Guide". "Transfer Size" gets a 16-bit field (because VMS QIO interface only provides for a 16-bit return value on the actual number of bytes read in the IOSB structure). --------------------------------------------------------------- 2: PTR 70-5-281 LPD Print Symbiont Problem --------------------------------------------------------------- Problem: LPD print symbiont inserts LF character after setup module. Solution: The following two logicals have been added for the LPD print symbiont to fix this: Defining the logical UCX$LPD_SETUP_NOLF will suppress the LF characters on a per-system basis. Defining the logical UCX$LPD__SETUP_NOLF will suppress the LF characters on a per-queue basis. Reference: PTR 70-5-281 / CFS.51026 / UTO101399 --------------------------------------------------------------- 3: PTR 70-5-773 Documentation Change --------------------------------------------------------------- Problem: Backlog parameter is ignored in a call to listen(). Solution: Fix documentation in UCX System Service & C Socket Programming Guide. On p. 6-11 which documents listen(), change: If a connection request arrives with the queue full (more than backlog connection requests pending), the client receives an error with an errno of ECONNREFUSED. to: If a connection request arrives with the queue full (more than backlog connection requests pending), the request is ignored so that retries inherent in TCP may succeed. If the backlog has not cleared by the time TCP times out, the connect() will fail with ETIMEDOUT. On p. 4-55 which documents QIO IO$_SETMODE/IO$_SETCHAR, change: If more connections are received than have been specified, then the additional connections are rejected. to: If more connections are received than have been specified, then the additional connections are ignored so that retries inherent in TCP may succeed. Reference: PTR 70-5-773 / CFS.55406 / MGO103148 --------------------------------------------------------------- 4: PTR 70-5-942 Documentation Change --------------------------------------------------------------- Problem: The l_linger time value is ignored when setting the socket SO_LINGER option. Solution: This fix is too complex for an ECO. Documentation changes need to be made to the System Services and C Socket Programming Guide to eliminate the references to this parameter that indicate that it is used. Documentation: The following changes need to be made to System Services and C Socket Programming Guide: On p. 6-62 delete the paragraph: SO_LINGER uses a linger structure parameter defined in the file. This structure specifies the desired state of the option and the linger interval. The option value for the SO_LINGER command is the address of a linger structure. See Section 5.8.4 for a description of the linger structure. On p. 6-62 delete the line in the next paragraph: A timeout period, called the linger interval, is specified in l_linger. On p. 5-5 delete the line at the bottom of the page: l_linger is the number of seconds to linger (the default is 120, or 2 minutes). The reason for deleting these paragraphs is because the use of the l_linger parameter was never implemented and has been determined to be too risky to implement as an ECO. Reference: PTR 70-5-447 / CFS.53296 / MGO102981 QAR 70-5-924 --------------------------------------------------------------- 5: PTR 70-5-949 NFS Server Problem --------------------------------------------------------------- Problem: NFS: Server is not responding %UCX-E-NORESPOND after a DIR command from the client. Solution: Suggested tuning change: When a directory is very large, doing a DIR to access the directory may appear to hang on the client and invoking the nfs server will get the message "NFS: Not responding". When the directory cache is built then NFS responds. Section 14.13 of the TCP/IP Services for OpenVMS/Management describes different changes that can be done to improve the server performance. Changing UCX$CFS_CACHE_SIZE is one of the ones that may help. --------------------------------------------------------------- 6: PTR 70-5-792 F$GETDVI Problem --------------------------------------------------------------- Problem: F$GETDVI("TT","TT_ACCPORNAM") continues to provide the "old" name for a renamed host. Solution: The INET ACP maintains a small 20-entry cache for IP address <--> hostname translation to speed acceptance of incoming telnet and rlogin sessions. This cache was designed without any means to invalidate renamed entries, although over time old entries will be pushed out to make room for new entries. The cache is cleared only when UCX is started. To redesign the cache with an invalidation mechanism when hosts are renamed is beyond the scope of an ECO. There are some possible avoidances which involve switching from using hostname (which can change during the lifetime of a session) to using IP address instead (which is immutable for the lifetime of a session): 1. Modify the Telnet and/or Rlogin services to specify /LOG_OPTIONS=(ADDRESS). This will cause the INET ACP's cache to be bypassed and the IP address (in dotted-decimal form) to be provided by TT_ACCPORNAM rather than hostname: $ write sys$output F$GETDVI("TT","TT_ACCPORNAM") would now show something like: Host: 16.20.208.147 Port: 42124 2. Parse SYS$REM_ID for IP address. For Telnet & FTP the form of this logical is TELNET_ and FTP_, respectively. SYS$REM_ID does not appear to be used for Rlogin. --------------------------------------------------------------- 7: PTR 70-5-896 COPY/FTP Problem --------------------------------------------------------------- Problem: COPY/FTP *.* host::dir, which used to copy all files to the remote system's "dir" subdirectory in 4.1 SSB, now fails with "553 dir: Is a directory." (Unix target) or "550 dir: Access is denied." (VMS target). Solution: 4.1 SSB was being generous in supporting this ambiguous remote file specification where "dir" can be interpreted as being either the name of a directory or the name of a file. In 4.1 ECO F and 4.2, the COPY/FTP operation was rewritten to improve support for non-VMS remote systems and in the process the interpretation was necessarily changed such that "dir" is treated as a filename as it would be if the VMS COPY command parsed this. To restore the original 4.1 SSB behavior would be a step backwards; however there are viable workarounds for a variety of target platforms: Unix: COPY/FTP *.* host::"dir/" WinNT: COPY/FTP *.* host::"dir\" VMS: COPY/FTP *.* host::[.dir] Note that the use of double-quotes is necessary when specifying a non-VMS pathname style. --------------------------------------------------------------- 8: PTR 70-5-991 Documentation Change --------------------------------------------------------------- Problem: Installation errors with UCX V4.2 ECO 2 after OpenVMS upgrade from 6.2 to 7.1. Solution: The DIGITAL TCP/IP Services for OpenVMS Release Notes manual states in Section 2.3.1 Reinstall UCX After OpenVMS Upgrade on page 2-2: If you upgrade from OpenVMS Version 6.2 to OpenVMS Version 7.0 or 7.1, you must reinstall the UCX software to ensure the correct image compatibility. This section should read: If you upgrade from OpenVMS Version 6.2 to OpenVMS Version 7.1, you must remove UCX and then reinstall UCX to ensure the correct image compatibility. To remove UCX on an Alpha system use PRODUCT REMOVE. To remove UCX on a VAX system use SYS$UPDATE:UCX$CLEANUP.COM. References: PTR 70-5-991 / PTR 70-5-975 / CFS.65871 / SOO101227 PTR 70-5-1112 / CFS.69400 / ZPO020971 UCX Notes 6846, 6778 --------------------------------------------------------------- 9: PTR 70-5-958 NFS ECO 3 Large File Support --------------------------------------------------------------- Problem: ACCVIO when exporting files greater than 2GB. This prevents using files greater than 2GB and less then 4GB in size via NFS. Solution: Fixed the handling of files that are greater than 2GB in size. This fix will only handle files up to 4GB-1 in size. Reference: PTR 70-5-958 / CFS.65376 / EVT102774 CAUTION: The NFS V2 protocol supports file sizes between 2G and 4G temporarily because NFS V3, which supports much larger files, is not yet available with TCP/IP Services for OpenVMS. Therefore, if you upgrade from V4.2 ECO3 to V5.0, you will lose support for file sizes between 2G and 4G. If you upgrade to V5.0A or any future V5.0-based maintenance release, support for file sizes in this range cannot be guaranteed. When NFS V3 is available with TCP/IP Services, it will support both V2 and V3 protocols, depending on what protocol version is requested by the NFS client. At that time, files larger than 2G will be usable only by NFS clients that request the V3 protocol. --------------------------------------------------------------------------- You can install this update kit on the following OpenVMS systems running DIGITAL TCP/IP Services for OpenVMS V4.2: * OpenVMS Alpha V6.2 and V7.1. ========================================================================= Postinstallation Notes. To complete the installation, do the following: 1. Copy SYS$MANAGER:UCX$RSHD_STARTUP.COM to SYS$SYSDEVICE:[UCX$RSH]. 2. Copy SYS$MANAGER:UCX$REXECD_STARTUP.COM to SYS$SYSDEVICE:[UCX$REXEC]. 3. Copy SYS$COMMON:[SYSMGR]UCX$SNMP_SHUTDOWN.COM to SYS$SYSDEVICE:[UCX$SNMP]UCX$SNMP_SHUTDOWN.COM. 4. Copy SYS$COMMON:[SYSMGR]UCX$SNMP_STARTUP.COM to SYS$SYSDEVICE:[UCX$SNMP]UCX$SNMP_STARTUP.COM. ========================================================================= The following sections describe the corrections to each facility. --------------------------------------------------------------------------- Corrections for DIGITAL TCP/IP Services V4.2 INSTALL Images --------------------------------------------------------------------------- ECO 1 updates: -------------- ECO A 13-MAR-1998 Alpha and VAX Images: UCX$VERSIONS.EXE UCX V4.2-21A Sources: UCX$CONFIG.COM V4.2-21 Problem: UCX$CONFIG does not operate in a configuration where the first network device configured is not the "A" controller. It assumes there will always be an _EWA0:, if it is to also configure an _EWB0. Unfortunately, this particular assumption does not hold true for all but one of the partitions in a Galaxy configuration. Solution: UCX$EDEV was updated to reflect the use of an EW-class Ethernet device. ECO A 13-MAR-1998 Alpha and VAX Sources: UCX$SNMP_SHUTDOWN.COM V1.0-02 UCX$SNMP_STARTUP.COM V1.0-02 Problem: There are inconsistencies in startup/shutdown of subagents. Also, some process names (e.g., those ending in hyphen) need to be enclosed in quotation marks so as not to confuse DCL. Solution: Make sure both subagents are handled, and enclose results of getjpi for PRCNAM in quotes. Also make checking of privileges, installation and removal of images, and enable/disable of service consistent between the procedures. Add P1 option to control use of privilege setting and install since some changes in ECO would not work with autostart invocation of startup which uses non-privileged UCX$SNMP account. The UCX$SNMP_SHUTDOWN.COM must be run from a privileged account. The procedure deinstalls UCX SNMP images and disables the SNMP service. UCX$SNMP_STARTUP.COM runs in two modes: Default: This is the non-privileged mode in which the procedure is called from UCX$STARTUP.COM and for autostart from the Auxiliary server. Full: This mode is intended for interactive startup from a privileged account. Use the command: $ @SYS$MANAGER:UCX$SNMP_STARTUP FULL This mode is required if you want to restart SNMP after running UCX$SNMP_SHUTDOWN without stopping and restarting UCX. Reference: Internal testing. ECO B 03-MAR-1998 Alpha and VAX Sources: UCX$NFSSETUP.COM UCX$NFSSETUP_HELP_CLIENT.DAT UCX$NFSSETUP_HELP_SERVER.DAT UCX$NFSSETUP_HELP_MAIN.DAT UCX$BINDSETUP.COM UCX$BINDSETUP_HELP.TXT Problem/Solution: Updated UCX$BINDSETUP command procedure. Included UCX$NFSSETUP command procedure. ECO B 06-MAR-1998 Alpha and VAX Sources: SYS$NET_SERVICES_UCX.COM Problem/Solution: Prior versions of this file would complain about UCX$INET_* logical names being defined if network services were registered before UCX$STARTUP.COM had been executed. This is the usual case at OpenVMS system startup. This ECO allows the registration of TCP/IP without such errors. This ECO uses the same lexical case for the host (node) name registration as is used in the UCX$INET_HOST and UCX$INET_DOMAIN logical names. Previous versions would uppercase the fully qualified host name. ECO B 06-MAR-1998 Alpha and VAX Sources: UCX$REXECD_STARTUP.COM UCX$RSHD_STARTUP.COM Problem/Solution: An attempt to $RCP between systems running UCX 4.1 (and possibly earlier) and UCX 4.2 would fail with the error %RCP-E-INVRESP. This error may also occur with two systems running UCX 4.2 where the SYS$MANAGER:UCX$REXECD_STARTUP.COM and SYS$MANAGER:UCX$RSHD_STARTUP.COM files have not been copied to the appropriate directories after the UCX 4.2 installation. PLEASE NOTE: The ECO installation places these two files in SYS$MANAGER:. To complete the solution, you must manually copy the files to the proper directories and ensure that file ownership and protection are correct. For example (please follow local security policy in setting file protections): $ copy SYS$MANAGER:UCX$REXECD_STARTUP.COM SYS$SYSDEVICE:[UCX$REXEC] $ set file/owner=parent/protection=(S:RWE,O:RWED,G:RE,W:RE) - SYS$SYSDEVICE:[UCX$REXEC]UCX$REXECD_STARTUP.COM; $ copy SYS$MANAGER:UCX$RSHD_STARTUP.COMSYS$SYSDEVICE:[UCX$RSH] $ set file/owner=parent/protection=(S:RWE,O:RWED,G:RE,W:RE) - SYS$SYSDEVICE:[UCX$RSH]UCX$REXECD_STARTUP.COM; Failure to copy both files or to properly set file ownership and protection might cause RSH, REXEC, and/or RCP to either fail or to act inconsistently depending upon whether the /USER qualifier or proxy is used. ECO B 13-MAR-1998 Alpha and VAX Images: UCX$VERSIONS.EXE UCX V4.2-21B Problem/Solution: Corrected to display a patch version properly. Reference: Internal testing. ECO 2 updates: -------------- ECO C 28-APR-1998 Alpha and VAX Sources: UCX$SHUTDOWN.COM Problem: When logged in on a system with tn device and trying to shutdown UCX, the customer gets unrecognized command messages. Solution: Define SAY as SYS$OUTPUT at the top of the UCX$SHUTDOWN.COM file. Reference: PTR 70-5-446 / CFS.53292 / UTO101490 ECO C 28-APR-1998 Alpha and VAX Sources: UCX$LPD_STARTUP.COM UCX V4.1-01 UCX$LPD_SHUTDOWN.COM UCX V4.1-01 Problem: Some UCX$*.COM files are not respecting a customer's non-default setting for the UCX$LPD_PRINTCAP logical. The default setting is being restored when LPD is either restarted or UCX$CONFIG is run. Solution: In UCX$LPD_STARTUP.COM, only DEFINE UCX$LPD_PRINTCAP if it is not already defined. In UCX$LPD_SHUTDOWN.COM, do not DEASSIGN UCX$LPD_PRINTCAP. ECO C 28-APR-1998 Alpha and VAX Sources: UCX.PDF Problem: RFC1442.MY file is in kit but is not copied to the [.SNMP] subdirectory of UCX$EXAMPLES. Solution: Add line to do copy to [INSTALL]UCX.PDF. Reference: UCX Note 6380 ECO D 24-SEP-1998 Alpha and VAX Sources: UCX$CONFIG.COM Images: UCX$VERSIONS.EXE UCX V4.2-21D Problem: Pointing to 127.0.0.1 as BIND server will give you the following error: UCX> show host /server=127.0.0.1 %UCX-W-BIND_NOSERVNAM, Server with address 127.0.0.1 is not responding %UCX-E-BIND_NOSERVERS, Default servers are not available %UCX-W-NORECORD, Information not found -UCX-E-BIND_NOSERVERS, Default servers are not available Solution: Modify the UCX$CONFIG.COM to add the entry for LOCALHOST. Reference: QAR 30-2-546 ECO E 16-OCT-1998 Alpha and VAX Sources: UCX$SNMP_STARTUP.COM Problem: Undesired purges could occur in SYS$MANAGER. Solution: Comment out the following lines from UCX$SNMP_STARTUP.COM: $ SAVE=5+2*F$GETSYI("CLUSTER_NODES") $ PURGE/KEEP='SAVE' Reference: None. ECO 3 updates: -------------- ECO F 29-JAN-1999 Alpha and VAX Sources: UCX$CONFIG.COM Problem: INSTALL: @sys$manager:ucx$config all enable does not configure mount in the configuration database. Solution: The UCX$CONFIG.COM file was changed to disable and enable mount when nfs is being disabled or enabled. Reference: PTR 70-5-932 / CFS.64690 / BRO101311 ECO G 08-APR-1999 Alpha and VAX Sources: UCX$RSHD_STARTUP.COM Problem: Some VAXeln clients will experience difficulty initiating rsh commands on OpenVMS system due to a change introduced in UCX V4.0 ECO #1. Solution: This change adds a comment to the UCX$RSHD_STARTUP.COM command procedure showing how to avoid this problem if necessary. Reference: PTR 70-5-942 / CFS.65126 / KAOQB0770 ECO H 07-JUL-1999 Alpha and VAX Images: UCX$UCP_HELP.HLB Problem: UCX SET SERVICE/ACCEPT=HOST=(*.domain) yields UCX-E-NOWILD error. On-line UCX Help indicates that wildcards can be used for this operation. Solution: Wildcard use with /ACCEPT and /REJECT lists is only supported for NOHOSTS= and NONETWORKS= to delete all the entries that had been set up on the respective list with prior HOSTS= or NETWORKS= operation(s) (in which wildcards are not permitted). Fixed the on-line help for the SET SERVICE and SET COMMUNICATIONS options /ACCEPT and /REJECT to clarify this. Reference: PTR 70-5-882 / CFS.63089 / HPAQA08HR / UCX Note 6582 ECO H 07-JUL-1999 Alpha and VAX Problem: Installation errors with UCX V4.2 ECO 2 after OpenVMS upgrade from 6.2 to 7.1. Solution: If you upgrade from OpenVMS Version 6.2 to OpenVMS Version 7.1, you must remove UCX and then reinstall UCX to ensure the correct image compatibility. To remove UCX on an Alpha system use PRODUCT REMOVE. To remove UCX on a VAX system use SYS$UPDATE:UCX$CLEANUP.COM.

IGMP messages were no longer being sent, and the SO_BROADCAST option was required in order to send Multicast datagrams. Solution: Skip several broadcast-related checks in the case of Multicast data. Ensure that IGMP messages are sent, and that other Multicast packets are looped back upon transmit for other sockets on the local host. Note that packets larger than the MTU are still not looped back, but this should be a highly unusual case.

In some circumstances, the active service counter was decremented below zero, resulting in an inability to accept further connections. 2. Termination AST's for created server processes were missed, leading to inaccurate service counts and occasional RWMBX hangs. Solution: 1. Test to avoid decrementing this counter below zero. 2. Rather than queuing an AST each time a server process is started, queue only one. When it triggers, queue another.

This can be an issue for customers with multiple subnets on the same wire. Solution: Enhance UCX to behave similarly to Digital Unix, that is, the conditions for broadcasting to the limited broadcast address are the same two that apply to Digital Unix: (1) The socket must be bound to a local interface, and (2) The SO_DONTROUTE socket option must be set. In an emergency the fix can be disabled by clearing the limited_bcast longword.

Reference: PTR 70-5-1074 / CFS.67243 / BCGM40KS1 PTR 70-5-1092 / CFS.68867 / MGO13335A ECO AA 01-JUL-1999 Alpha and VAX Problem: F$GETDVI("TT","TT_ACCPORNAM") continues to provide the "old" name for a renamed host. Solution: The INET ACP maintains a small 20-entry cache for IP address <--> hostname translation to speed acceptance of incoming telnet and rlogin sessions. This cache was designed without any means to invalidate renamed entries, although over time old entries will be pushed out to make room for new entries. The cache is cleared only when UCX is started. To redesign the cache with an invalidation mechanism when hosts are renamed is beyond the scope of an ECO. There are some possible avoidances which involve switching from using hostname (which can change during the lifetime of a session) to using IP address instead (which is immutable for the lifetime of a session): 1. Modify the Telnet and/or Rlogin services to specify /LOG_OPTIONS=(ADDRESS). This will cause the INET ACP's cache to be bypassed and the IP address (in dotted-decimal form) to be provided by TT_ACCPORNAM rather than hostname: $ write sys$output F$GETDVI("TT","TT_ACCPORNAM") would now show something like: Host: 16.20.208.147 Port: 42124 2. Parse SYS$REM_ID for IP address. For Telnet & FTP the form of this logical is TELNET_ and FTP_, respectively. SYS$REM_ID does not appear to be used for Rlogin.

The ICMP port unreachable error is being reported to *all* sockets bound to the local interface receiving the error, not just the socket tickling the port that resulted in the error. Solution: UCX is based on older Berkeley code which was not designed to discriminate the delivery of ICMP errors based on port number, which this particular error is best suited for. (TCPIP V5 is much more modern and has such code.) Rather than redesign UCX, which would be risky at this stage of its life, UCX was modified to simply not deliver an ICMP Port Unreachable error to any socket. Since UDP is an inherently unreliable protocol, UDP applications can not depend on receiving such error indications anyway.

A converse situation also exists: if the first TFTP connection comes from an accepted host, TFTP will accept all further requests, even those from rejected hosts. Solution: The first problem, a denial-of-service issue, occurred because the INETACP was leaving the rejected TFTP request in the TFTP service's receive socket buffer, where it was reprocessed (and re-rejected) for every new request that came in. The INETACP now clears rejected requests from the socket. The second problem, a security concern, occurs because the INETACP spawns a TFTP process to service all future TFTP requests when the first acceptable request comes in, and it passes off the TFTP service socket to that process. Accept/Reject processing only occurs within the INETACP -- there is no code in TFTP to do this itself. This is a design limitation of the INETACP and TFTP service which is not fixable within the scope of an ECO. For sites that consider this a serious security issue, two workarounds exist: (1) disable the TFTP service entirely, or (2) configure UCX to reject *all* communications from a rejected host/network (using SET COMM/ACCEPT/REJECT) instead of configuring it on a per-service basis.

Solution: The major reason this problem occurred is that OpenVMS changed the value of the name of a bit position in a TTY UCB (such as a TNDRIVER UCB) in OpenVMS V6.2. In particular, symbol TTY$V_FD_BUSY was defined as bit 8 in OpenVMS versions prior to V6.2, and it was redefined to be bit 10 in V6.2. The TNDRIVER distributed for all VAX platforms uses the old definition and for Alpha platforms running, V6.2 of OpenVMS, the TNDRIVER built for V6.2 uses the old definition. The result is that the wrong bit was being tested on systems where the definitions were out of synch. The solution was to devise a new test of the condition that works on all platforms.

Solution: Use the INTS.H definitions for int32, uint32, int64 and uint64. This prevents the %CC-E-NOLINKAGE errors that were generated at compile time if both RPC.H and PTHREAD.H were included. INTS.H properly defines int32 and uint32 for both current platforms and properly defines int64 and uint64 for the Alpha platform. However, if the platform is VAX, INTS.H does not define either int64 or uint64. This is an acceptable solution because none of the provided source code in either RPCXDR or PCNFSD uses either int64 or unit64. Therefore, these typedefs are only used in customer applications. If a customer application is currently using the misdefined 32-bit typedefs int64 and/or uint64 on either platform, the solution would be to modify the source code of the application to use int32 and/or uint32 and recompile.

Solution: Instead of forming the subagent name from full host name + PID (with truncation occurring after 25 characters), use only the first 22 characters of the host name.

(Unix target) or "550 dir: Access is denied." (VMS target). Solution: 4.1 SSB was being generous in supporting this ambiguous remote file specification where "dir" can be interpreted as being either the name of a directory or the name of a file. In 4.1 ECO F and 4.2, the COPY/FTP operation was rewritten to improve support for non-VMS remote systems and in the process the interpretation was necessarily changed such that "dir" is treated as a filename as it would be if the VMS COPY command parsed this. To restore the original 4.1 SSB behavior would be a step backwards; however there are viable workarounds for a variety of target platforms: Unix: COPY/FTP *.* host::"dir/" WinNT: COPY/FTP *.* host::"dir\" VMS: COPY/FTP *.* host::[.dir] Note that the use of double-quotes is necessary when specifying a non-VMS pathname style.

(70-5-1001) Solution: [1] In the FTP client, when a target file has been specified, don't touch its type or version fields; this is only done when automatically generating a target file specification from the source file specification. Also no longer convert a version separator ';' to '.' when doing VMS-to-VMS (VMS Plus) transfers. This makes the filename conform better to VMS standards in %FTP-S-COPIED messages. [2] In the FTP client, eliminate the possibility of an infinite loop when dealing with errors in this situation. Second, try to prevent the RMS-F-IFI error from occurring -- it can only result from a previous file transfer that was not properly cleaned up.

(70-5-954) [2] FTP Client does not send STRU R files correctly in ASCII mode. Regression from UCX V4.0 ECO stream. (70-5-1107) Solution: [1] The algorithm FTP used to convert VFC/PRN-format files made certain assumptions about the VFC prefix and suffix codes when mapping records to FTP ASCII "lines of text" on the wire, which according to the RFC must end with (or end-of-record <01> for STRU R files). The algorithm works fine for common VMS listing and log files which are VFC/PRN format, but can fail in the general case for files written by customer Cobol applications. Fixed FTP's conversion algorithm to perform a more faithful conversion of VFC/PRN prefix/suffix code combinations with a better mapping to FTP ASCII records on the wire. This affected both the client (Put/Convert) and the server (UCX$FTP_CONVERT_FILE logical). Also fixed bug in server which has prevented VFC conversion from working at all since early in the UCX 4.1 ECO stream. [2] FTP client was sending <00> instead of <01> as the end-of-record tag. Fixed it to send the proper <01> sequence. The server, which has similar code, did not suffer from this problem. Both client and server appear capable of receiving STRU R-format in ASCII mode okay.

For example: COPY/FTP remote"user pwd"::login.com [] retrieves remote"user pwd"::login.com;2 --> []login.com;1 and remote"user pwd"::login.com;1 --> []login.com;2 Solution: Fixed COPY/FTP (get) and FTP GET command operations in VMS Plus mode (VMS-to-VMS) to behave much more like the VMS $COPY command behaves (with /NOCONCAT option): - only retrieve the highest version when no version is specified; - preserve version number of source file when possible; - disallow overwriting (superceding) an existing version of a file (both client and server); and - in circumstances for which the previous change is not desirable, create a new version to avoid a conflict with an existing version. Note that it is still possible to end up with reversed versions when retrieving all versions of a file (e.g. COPY/FTP remote"user pwd"::login.com;* []) and those versions already exist locally. This is exactly how VMS $COPY/NOCONCAT behaves in this circumstance.

Solution: This class of problem (error propagation out to DCL $status) has been a thorn in UCX FTP client's side for a long time. (The FTP client was originally designed with interactive use only in mind.) Several prior fixes have plugged a hole here or there. This solution caplitalizes on a comprehensive review of FTP code that was done for TCPIP V5.0A and backports into UCX much of the error propagation improvements that were made in that release. For the reported problem, send_data() was modified to return FTP$_COPIED only on success, and FTP$_NOTCOPIED on failure. NOTE: This change could "break" batch-mode FTP scripts which "relied" on FTP's lack of error propagation. A workaround exists for such situations: In the file SYS$LOGIN:FTPINIT.INI (or the file referenced by a logical named "FTPINIT"), include the following FTP command: set error_level error This instructs FTP not to abort (in batch mode) when a non-fatal error is encountered.

Solution: FTP server handling of STOU command had been modified in 4.1 ECO and 4.2 to no longer generate a weird-looking unique filename (which apparently wasn't always unique), but to instead exploit RMS' file versioning scheme by forcing a new (unique) version for the specified file. Unfortunately, code to override an explicit version specified in the target filename was only implemented for the case of storing non-VMS-Plus ASCII files. Fixed the FTP server STOU operation to create a new version for the file regardless of any specified version or file transfer mode (ASCII, BINARY, VMS-Plus).

For example: COPY/FTP remote"user pwd"::login.com [] retrieves remote"user pwd"::login.com;2 --> []login.com;1 and remote"user pwd"::login.com;1 --> []login.com;2 Solution: Fixed COPY/FTP (get) and FTP GET command operations in VMS Plus mode (VMS-to-VMS) to behave much more like the VMS $COPY command behaves (with /NOCONCAT option): - only retrieve the highest version when no version is specified; - preserve version number of source file when possible; - disallow overwriting (superceding) an existing version of a file (both client and server); and - in circumstances for which the previous change is not desirable, create a new version to avoid a conflict with an existing version. Note that it is still possible to end up with reversed versions when retrieving all versions of a file (e.g. COPY/FTP remote"user pwd"::login.com;* []) and those versions already exist locally. This is exactly how VMS $COPY/NOCONCAT behaves in this circumstance.

ECO C 28-SEP-1998 Alpha and VAX Images: UCX$LPRSETUP.EXE UCX V4.2-21C Problem: At OpenVMS 7.1, the spool directory is not created automatically when using UCX$LPRSETUP, nor is any message produced to warn the user of this problem. However, the directory is easily created manually. Solution: A mkdir() 3rd uic arg bug in VMS 7.x has been reported to the DECC folks (DECC Note 2659). In the interim, it seems viable to workaround the mkdir() by changing UCX$LPRSETUP to use the standard 2-arg mkdir() call and to properly report any problems in doing so. Since most users of UCX$LPRSETUP would be privileged (System Administrators), they would likely have one of the GRPPRV, SYSPRV, or BYPASS privileges which forces even the standard 2-arg mkdir() to create spool directories owned by the parent [UCX$AUX,UCX_LPD]. (The SYSTEM account is typically configured with such privileges.) Unprivileged users are not able to create spool directories due to insufficient permissions anyway. With this code in place, sufficiently privileged users can create spool directories via UCX$LPRSETUP regardless of whether the release of OpenVMS contains the mkdir() bug or not. WriteEntry() was also changed to only call MakeSpool() when writing the entry to the PRINTCAP file, and not when writing it to the LOG file. This change seems prudent -- now that the user is informed of mkdir() errors, the directory should only be created once!

Provide a new bit in UCX$TELNETSYM_SUPPRESS_FORMFEEDS (bit 3, value 8) that extends the TelnetSym's search for a formfeed to suppress beyond the first output buffer until an actual formfeed is found.

Solution: The problem occurs because OpenVMS callable mail reads the entire mail message. If the process does not have enough memory, callable mail returns MAIL-W-NOMOREREC.

Solution: If POP's patch_from_line() call to SMTP's build_path_from() routine fails with UCX$_SMTP_PARSERR, and the From: address begins with the SMTP%" jacket, then relax the ignore_mail11_headers constraint that the VMS mail From: address must be RFC822 and treat it as if it really was RFC822/SMTP compliant.

Solution: The crash was addressed by Kernel ECO F 24-JUN-1998 fix. RSH client hang is caused by kernel's in_pcbbind() not returning EADDRINUSE in one instance where it probably should. Rather than destabilize the kernel in this heavily-used area, worked around the problem in RSH by having it bind its stderr connection to an explicit address of a local interface rather than INADDR_ANY.

Solution: The RPC message appears to be short by four bytes. Checking the source revealed that if the first four bytes encode properly, the second four bytes will not be encoded because an || was being used instead of an && condition. Reference: PTR 70-5-629 / CFS.56410 / HPAQC11RL ECO 2 updates: ------------- ECO B 27-MAY-1998 Alpha and VAX Sources: [RPCXDR]types.h The file types.h belongs in the system directory: SYS$COMMON:[UCX$LIB.RPC] Problem: DECC compiler on Alpha fails with "%CC-E-NOLINKAGE" errors on typedefs: int32, uint32, int64 & uint64 Solution: Use the INTS.H definitions for int32, uint32, int64 and uint64. This prevents the %CC-E-NOLINKAGE errors that were generated at compile time if both RPC.H and PTHREAD.H were included. INTS.H properly defines int32 and uint32 for both current platforms and properly defines int64 and uint64 for the Alpha platform. However, if the platform is VAX, INTS.H does not define either int64 or uint64. This is an acceptable solution because none of the provided source code in either RPCXDR or PCNFSD uses either int64 or unit64. Therefore, these typedefs are only used in customer applications. If a customer application is currently using the misdefined 32-bit typedefs int64 and/or uint64 on either platform, the solution would be to modify the source code of the application to use int32 and/or uint32 and recompile.

A +/- 1 hour shift depends on DST. Solution: Base time offset on file time, not current time. Reference: PTR 70-5-968 / CFS.65783 / EVT102794 PTR 70-5-484 / CFS.53930 / MCSM907Z5 ECO B 11-JUN-1999 Alpha and VAX Images: UCX$RCP.EXE UCX V4.2-21B Problem: COPY/RCP on a binary file changes the file attributes from fixed length to STREAM LF and corrupts the file. Solution: RCP will now treat VMS fixed-length (FIX) and undefined (UDF) format files as binary and copy them verbatim without doing the implicit conversion to Stream_LF. Note however that RCP will NOT preserve file attributes on the target file (which will still be created as Stream_LF). To fix this is beyond the scope of an ECO and may not be possible without incompatibly breaking the RCP protocol. File attributes on the target will have to manually be corrected by the user. Lest some customers have come to depend on the original behavior of RCP, that behavior can be restored by setting the logical UCX$RCP_SEND_FIX_FORMAT_AS_ASCII to "1", "True", or "Yes".

Solution: Added an option similar to Unix NTP which allows the correction of any time difference, including times greater than the maximum aperture. The flag is not set by default, which means that if the time difference is too large (around 5.3 hours or so) then the following message will appear in the log file: seconds is too large (set clock manually or set correct-any). To set the option, CORRECT-ANY is added to the UCX$NTP.CONF file which after doing the filtering and finding the difference to be too large, it will reset the time.

Mounting of disk fails with the loss of dynamic proxy. Solution: Prevent dynamic proxies from changing to an unknown name like a zero (0) length name.
