ECO KIT SUMMARY:
An ECO kit exists for TCP/IP V4.2 on OpenVMS Alpha V6.2 through 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$LPD_<queue>_SETUP_NOLF will
suppress the LF characters on a per-queue basis.
Reference:
PTR 70-5-281 / CFS.51026 / UTO101399
---------------------------------------------------------------
3: PTR 70-5-773 Documentation Change
---------------------------------------------------------------
Problem:
Backlog parameter is ignored in a call to listen().
Solution:
Fix documentation in UCX System Service & C Socket Programming
Guide.
On p. 6-11 which documents listen(), change:
If a connection request arrives with the queue full (more
than backlog connection requests pending), the client
receives an error with an errno of ECONNREFUSED.
to:
If a connection request arrives with the queue full (more
than backlog connection requests pending), the request is
ignored so that retries inherent in TCP may succeed. If
the backlog has not cleared by the time TCP times out, the
connect() will fail with ETIMEDOUT.
On p. 4-55 which documents QIO IO$_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
<socket.h> 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.

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$REM_ID for IP address. For Telnet & FTP
the form of this logical is TELNET_<ipaddr-in-hex>
and FTP_<ipaddr-in-hex>, respectively. SYS$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.

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.
---------------------------------------------------------------------------

---------------------------------------------------------------------------
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.

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.

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.

upgrade from 6.2 to 7.1.
Solution:
If you upgrade from OpenVMS Version 6.2 to OpenVMS Version

Problem:
If in UCX$CONFIG or TCPIP$CONFIG you go into 1-"Core Environment"
and then 4-"Interfaces" and change the internet address to a
different subnet address, the question "Enter broadcast mask for
xxxx" shows the old "Broadcast Address" and does not default to
the new "Broadcast Address". This often means that customers end
up with the wrong "Broadcast Address". This problem also exists
with the network mask default.
Solution:
Make sure the default values for the network mask and broadcast
mask are recalculated after a new IP address is entered.

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.

Problem:
SW "LAND ATTACK" hangs VMS on Alpha and VAX (also called
Denial of Service Attack). The machine goes into an
infinite loop and consumes all available cpu cycles. The
listen port under attack becomes completly unresponsive

Problem:
A UCX program sends UDP packets to the limited broadcast
address 255.255.255.255, incorrectly sends to
{<Network-number>, 255}. 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.

Problem:
System can crash when SSRVEXCEPT while processing an

Solution:
In routine INETACP_GET_USER_INFO, if we get an error
condition, we wind up calling INETACP_SERV_ACCEPT_SYS_ERROR,
which finally winds up in routine INETACP_SERV_ACCEPT_CLOSE,
which expects R5 to be pointing at the acceptor UCB.
Therefore, before calling INETACP_SERV_ACCEPT_SYS_ERROR,
refresh R5.

Problem:
System hang or CPUSPINWAIT crash occurs on Pathworks
shutdown.
Solution:
An optimization was introduced to the BGdriver a few
years ago specifically for Pathworks to coalesce
fragmented UDP packets received from the network. This
optimization failed to adjust the socket's accounting of
associated mbufs when a fragmented packet was coalesced,
causing an infinite loop to occur when the socket was
closed. Fixed to properly account for coalesced mbufs.

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$REM_ID for IP address. For Telnet & FTP
the form of this logical is TELNET_<ipaddr-in-hex>
and FTP_<ipaddr-in-hex>, respectively. SYS$REM_ID
does not appear to be used for Rlogin.

Problem:
UDP applications can receive SS$_REJECT error due to ICMP
Port Unreachable error caused by an entirely unrelated
application. 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.

Problem:
If TFTP service is configured with an accept or reject
host/network list, and the very first TFTP connection
comes from a rejected host, all subsequent TFTP requests
are rejected, even from acceptable hosts. 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.

Problem:
System crashed with INVEXCEPTN when Pathworks is shut down
to stop runaway UCX$PWIPACP_*.LOG, which shows errors like:
... *** sys$qio Accept failed ***. channel 272 error 676
... *** sys$qio Accept failed ***. channel 256 error 44
... *** sys$qio Accept failed ***. channel 256 error 44
which repeats ad nauseum. (The problem is not necessarily
unique to Pathworks, however.)
Solution:
This is regression from 70-5-963 fix introduced in 4.2-21S.
The probing of the output parameter buffer was misplaced
exposing a hole in which a listen socket could end up being
associated with more than one channel (UCB). Corrected by
relocating that fix to a safer place, eliminating the hole.

Problem:
RLOGIN server can hang during user proxy validation in
rare circumstance.
Solution:
This problem was diagnosed a while back as being caused
by the INET ACP calling $GETUAI system service while in
Kernel mode, leading to a deadlock situation in VMS/RMS.
The problem was fixed in TCPIP V5 but not brought back
to V4.x. Backported V5 fix to V4.x such that $GETUAI is
called in User mode.
Also corrected several incomplete or possibly corrupt
OPCOM messages produced by the INET ACP in this and
several other Rlogin rejection circumstances.

UCX$TNDRIVER.EXE UCX V4.2-21A
Problem:
System crashed in OpenVMS routine EXE$TIMEOUT while
servicing a corrupt fork and wait queue.
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.

Problem:
DECC compiler on Alpha fails with "%CC-E-NOLINKAGE"
errors on typedefs: int32, uint32, int64 & uint64
There are a number of workarounds available for this
problem.
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.

Problem:

this was on VMS 6.2, DEC C 5.7-004, link with
UCX$SNMP:ESNMP.OLB
Solution:
An element of "method" data structure was not getting
initialized within the calling code in esnmp_poll.c. Both
the calling code and the example were fixed. Error showed
up only on certain platforms and in link with .olb, not
shareable; could be that under certain conditions the
problem struct element was getting initialized to 0 by
chance or because of architecture, DEC C version, etc.

Problem:
Unable to run the examples UCX$CHESS_SUBAGENT because
the agent id name is wrongly truncated.
If the total length, including dots, of hostname + domain
(as returned by gethostname(), i.e., concatenation of
tcpip$inet_host + "." + tcpip$inet_domain) is > 25
characters, subagent init routine in may not generate a
unique name to register with in master agent, and
subagent can never start up.
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. This
allows for "_" and full 8 hex digits from PID. Since for
4.x master and subagents always run on the same host,
possible truncation of host name doesn't matter.

Solution:
A variable in routine getChan() was incorrectly
declared to be static. The result was that,
if the routine was ever entered simultaneously
(such as in normal mode and in an AST), data could be
corrupted. This day-one bug was dormant until the latest
release of PATHWORKS. With an older version of PATHWORKS,
conditions were such that the routine was never entered

set of calls into PWIP and the bug is now exposed. The
solution was to make the variable a normal automatic

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.

Problem:
[1] $ COPY/FTP A. B.DAT would drop a character off the
target filename, resulting in B.DA being created.
This would only occur when the source filename has
no type. (70-5-806)
[2] $ COPY/FTP of a wildcarded list of files can result
in a loop where the errors %FTP-E-INPROCF and
%RMS-F-IFI are reported ad infinitum, filling up log
files. (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.
The second piece of the fix was found to also apply
to FTP server code, where it could potentially
prevent channel leakage.

Problem:
[1] Put/Convert inserts extra LineFeeds (LF) when sending
certain VFC files. (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 <CR><LF> (or end-of-record <IAC><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 <IAC><00> instead of <IAC><01>
as the end-of-record tag. Fixed it to send the proper
<IAC><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.

Problem:
COPY/FTP (get) retrieves multiple versions of the specified
file when it shouldn't, and reverses the version ordering to
boot. 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.

Problem:
COPY/FTP returns a successful status (FTP$_COPIED)
even when the destination disk is full.
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.

Mput no longer passes the expanded result of its
SYS$PARSE down to wldcrd_put_process().

Solution:
FTP server handling of STOU command had been modified
in 4.1 ECO and 4.2 to no longer generate a weird-looking

forcing a new (unique) version for the specified file.
Unfortunately, code to override an explicit version
specified in the target filename was only implemented
