DEC TCP/IP] UCXALP_E10041 TCP/IP V4.1 ECO Summary
TITLE: DEC TCP/IP] UCXALP_E10041 TCP/IP V4.1 ECO Summary
Modification Date: 21-DEC-2000
Modification Type: DOCUMENTATION: Removed references to OpenVMS V7.2.
TCP/IP V4.1 is not supported on 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.

--------------
SPECIAL NOTE 20-SEP-1996
Problem:
Sites using the manual startup for the NFS
server may experience the server process
hanging in LEF state.
Solution:
There is no ECO correction for this problem. Sites
using manual NFS server startup should do one or both
of the following:
1. Use automatic startup instead.
2. Edit SYS$MANAGER:UCX$NFS_SERVER_STARTUP.COM as
follows:
- Find the RUN command following the MANUAL_STARTUP:
label.
- Change the last two continuation lines of the RUN
command, /UIC=[1,4] - /NORESOURCE to /UIC=[1,4]
thereby eliminating the /NORESOURCE_WAIT qualifier.

ECO A 19-AUG-1996 Alpha and VAX
Image:
UCX$VERSIONS.EXE UCX V4.1-12A
Problem:
UCX$VERSIONS shows the wrong images on VAX.
The V6 images are shown on V5 and V5 images on V6.
Solution:
Corrected.
References:
Internal report.
ECO B 24-NOV-1996 Alpha and VAX
Image:
None.
Problem:
UCX$FINGER_SHUTDOWN purged all logs,
not just UCX logs.
Solution:
Purge old log files at startup.
References:
Internal report.
ECO C 30-DEC-1996 Alpha and VAX
Image:
None.
Problem:
Shutting down OpenVMS from either an RLOGIN
or TELNET session resulted in the session being
aborted before the system was shut down.
Solution:
If invoking UCX$SHUTDOWN.COM on a TN device,
display an appropriate message and exit the
shutdown procedure. UCX remains running
until the system is shut down.
This behavior is the same as that of DECnet on RT terminals.
References:
CFS.47157.
ECO D 14-JAN-1997 Alpha and VAX
Image:
None.
Problem:
The METRIC daemon runs using the UIC and
default privileges of the user who started it.
The image is not installed during startup
unless either RSH or REXEC is enabled.
Solution:
Correct the startup logic for the METRIC daemon so
that it utilizes its own UIC and installs the images
whenever appropriate.
Reference:
CFS.47535.
ECO E 6-FEB-1997 Alpha and VAX
Images:
None
Problem:
Files get purged in SYS$MANAGER upon startup.
Solution:
UCX$STARTUP calls other startup scripts in SYS$MANAGER,
and they purge files they should not be purging. This problem
occurs because there are 2 identical copies of
startup/shutdown files for some components: one in the login
directory and one in SYS$MANAGER.
Removed purge commands from several startup scripts.
Reference:
CFS.48550.
ECO F 7-FEB-1997 Alpha and VAX
Images:
None
Problem:
UCX$SNMP_SHUTDOWN.COM cannot find the
SYS$SYSTEM:UCX$SNMP_AGENT.EXE file.
Solution:
Because the images has been replaced by
SYS$SYSTEM:UCX$ESNMP_SERVER.EXE, correct the file name and
process name. In addition, change the DCL code so that it
correctly identifies the process being stopped.

ECO 9 updates:
--------------
ECO I 8-FEB-1998 Alpha and VAX
Image:
UCX$VERSIONS.EXE UCX V4.1-12I
Sources:
UCX$SNMP_SHUTDOWN.COM V1.0-02
UCX$SNMP_STARTUP.COM V1.0-02
Problem:
Inconsistencies in startup/shutdown of subagents.
Also enclose some process names (e.g., those ending in a hyphen)
in quotation marks so as not to confuse DCL.
Solution:
Made sure both subagents handled, and enclosed results
of getjpi for PRCNAM within quotation marks. Also made checking
of privileges, installation and removal of images, and
enable/disable of service consistent between the procedures.
The UCX$SNMP_SHUTDOWN.COM must be run from a privileged
account. It deinstalls UCX SNMP images and disables the
SNMP service.
UCX$SNMP_STARTUP.COM runs in two modes:
Default:
The non-privileged the mode in which the
procedure is called from UCX$STARTUP.COM and for
autostart from the Auxiliary server.
Full:
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$SNMP_SHUTDOWN without stopping and
restarting UCX.
Reference:
Internal testing.
ECO 10 updates:
---------------
ECO K 28-APR-1998 Alpha and VAX
Sources:
[INSTALL]UCX$SHUTDOWN.COM
Problem:
When logged in on a system with tn device and trying to
shutown UCX, the customer gets unrecognized command messages.
Solution:
Define SAY as SYS$OUTPUT at the top of the UCX$SHUTDOWN.COM
file.
Reference:
PTR 30-1-446, CFS.53292
Sources:
UCX$LPD_STARTUP.COM UCX V4.1-01
UCX$LPD_SHUTDOWN.COM UCX V4.1-01
Problem:
Some UCX$*.COM files are not handling the UCX$LPD_PRINTCAP
logical correctly.
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.
Images:
UCX$VERSIONS.EXE UCX V4.1-12K

Problems:
1. The routing table becomes filled with entries that
have the RTF_UP flag bit cleared but have a
non-zero reference count.
2. A system crash might occur in the ip_output routine because
inp_route.ro_rt points to a deallocated entry.
3. On OpenVMS Alpha V7.0, a system crash might occur when a
reference is made to unallocated memory that is likely
a part of the MBSTAT_DATA cluster of large buffers.
Solutions:
1. In the ip_output routine in IP_OUTPUT_VMS.C, the
static global route structure iproute was being
overwritten without first doing an RTFREE of the
rtentry associated with the route. The result was an
rtentry whose refcnt was permanently increased by 1,
and which, therefore, never goes away. The solution
is to do the RTFREE.
2. In routine rtpurge, an incorrect call to rtfree has the
possibility of deallocating an rtentry while leaving an
inp_route.ro_rt field still pointing to it. This is the
same situation cited above. The solution is to remove
the call to RTFREE.
3. The problem occurs when the user issues:
UCX SET CONFIGURATION COMM/LARGE=MIN=31
31 large Ethernet buffers need more than 64K of memory
for a cluster of buffers with OpenVMS V7.0 because the
size of a VCRP has grown. The amount of space to allocate
is calculated, but the value is more than 16 bits.
When the space needed is specified, the low order bits are
used incorrectly. The unallocated space is then used and
causes the system to crash.
The correction consists of four parts:
a. A new INETCB$B_MAX_NR_DATA_CLST field is created
in the NETCB. The declaration of this field
occurs in INET_MACROS.MAR. The new field is in
a previously reserved area of the INETCB that was
used only for alignment purposes, and, therefore,
the INETCB has not grown in size. There is no
need to re-assemble many modules to use this new
field.
b. In the INETACP_MOUNT routine in INETACP_INIT.MAR,
the largest number of large buffers that fit
in a maximum-sized cluster is calculated. A maximum
sized cluster is at least one byte less than 64K.
The newly-calculated number is then put into the
new INETCB$B_MAX_NR_DATA_CLST field.
c. In INET_MBUF.MAR where the clusters of large
buffers are allocated, the number of buffers
to configure in a cluster using the number
specified by the user and the value contained
in INETCB$B_MAX_NR_DATA_CLST is minimized.
d. Some code cleanup is done in the SET_MIN_LARGE,
SET_MIN_SMALL, and INET_SET_SIZES_MIN routines
in INET_SETMODE.

Problem:
A potential problem exists for multicast on SLIP lines.
Once a datagram for an IP multicast address has been
received in a SLIP VCRP, the VCRP will, from then on,
continue to indicate that any datagrams processed in
that VCRP were received via a "broadcast" datalink
address.
Solution:
In the ALLOCATE_SLIP_RCV_VCRP routine, the datalink
received header field (@VCRP$A_LAN_R_HEADER which points
to VCRP$A_LAN_R_HEADER+4) is reinitialized to zero.

UCX$INTERNET_SERVICES_SEC_V6.EXE UCX V4.1-12C
UCX$INETACP.EXE UCX V4.1-12C
Problem:
1. The system pool fills up with VCRPs. This exhausts
pool and causes a CLUEXIT bugcheck. This problem
was initially reported in ECO M (V3.3).
2. When a persistent window probe message is received, UCX
TCP does not reply with an ACK message. Although there
is no explicit requirement to send such ACKs, certain
other implementations expect them. The lack of a response
prompts other TCPs to abort connections with full receive
windows, even though the connection is in fact still active.
Solutions:
1. This problem is not a UCX problem but rather a
datalink driver problem. However, a small amount of code
can be added to UCX to prevent the problem from crashing
the system. The problem is triggered by a broadcast storm
from an errant Windows NT node that produces thousands
of broadcast datagrams so quickly that all pool is overrun
even before initial notification of the existence of the
datagrams occurs. Normally UCX accepts a datagram from the
datalink driver and queues it for later processing so that
control can be immediately passed back to the datalink driver.
When the datalink finishes its tasks, the processing
of the datagrams in the queue begins. In this problem case,
the datalink receives so many datagrams that it does
not finish with its tasks until the queued datagrams occupy
all of pool. The included correction artificially limits the
number of such datagrams that will be queued back to
the datalink. When the number of unprocessed queued
datagrams passes a threshold value (1000 for now)
deallocation of all the datagrams above this threshold
occurs. This, in effect, prevents the datalink from
overrunning pool since each new received datagram can use
the deallocated space.
2. Send back an acknowledgment (ACK) indicating the same
sequence number that was just received. In other words,
do not acknowledge the single byte, which was beyond the
end of the allowable receive window. Simply repeat the
ACK for all prior data.

Image:
UCX$INETACP.EXE UCX V4.1-12D
Problem:
When a service is disabled while it still has active
connections, the global service counter still counts
those connections. When they are closed, the global
counter is not updated.
Solution:
Decrement the service counter for all outstanding
connections at the time the service is disabled.

UCX$INTERNET_SERVICES_SEC_V6.EXE UCX V4.1-12E
UCX$INETACP.EXE UCX V4.1-12E
Problem:
An application waiting for a given broadcast address
incorrectly receives broadcast messages addressed to the
network address of its second interface.
Solution:
Tighten up the address comparison and selection criteria
in INET_IN_OUT.MAR so it will be able to recognize when a
datalink level broadcast has been received over an interface
whose IP broadcast address does not coincide with the IP
broadcast destination of the received datagram. In this
case, discard the received datagram.

Problems:
1. On 32-bit systems (i.e., VAX and Alpha before OpenVMS
V7.0), systems running UCX V4.1 crash when DCE is
started.
2. On-64 bit systems, DCE gather writes do not work
properly.
Solution:
Both problems are due to errors in a routine that only
deals with scatter/gather I/O. The routine is
BUILD_MULTI_BUFFER_VECTOR.
For problem 1, there was an incorrect reference to R3
that should have been to R6. The result was that a
counter whose value should have been less than a maximum
of 200 was being loaded with arbitrary information. The
counter was then used to modify an array in memory. When
the counter contained large numbers, massive memory
corruption occurred.
For problem 2, the error was in code that prepared 32-
bit style descriptors for the 64-bit environment. The
result was that in a gather operation that specified 3
buffers, the descriptors for the first buffer were
replicated 3 times, rather than each of the three
individual buffers being replicated once.

UCX$INTERNET_SERVICES_SEC_V6.EXE UCX V4.1-12G
UCX$INETACP.EXE UCX V4.1-12G
Problems:
1. The TCPIPTRACE command intermittently caused access violations.
2. POP users notice occasional data duplication.
The problem that POP sees is actually more general.
The problem may occur on any non-blocking socket.
The problem arises when data is sent, the current
socket send quota is less than the amount of data to be
sent, and there is more additional room in the current
mbuf in the send socket buffer than the amount of
remaining quota. In this infrequent case, incorrect
I/O status is returned to the user. It does not
reflect that data was actually written to the socket.
The result is that the user will resend data that has
already been sent.
Solutions:
1. The alignment problem on Alpha platform has been corrected.
2. The partial send count is now properly updated after some data
has been transferred.

Problem:
Multiple ACCEPTs done to the same socket may cause an
I/O request to be lost. This situation results in a process
hanging in RWAST. This can occur with a multi-process
World-Wide Web (WWW) server.
Solution:
The cause of this problem is that a particular UCX-specific
field in the INET_SOACCEPT code flow in the IRP is being
used without being initialized. The result is that the
IRP$x_BG_OOB bit, in the IRP$L_FLAGS field, is possibly
being interpreted incorrectly. The solution is to introduce
an instruction that initializes the field to zero at the
start of an ACCEPT operation.

UCX$INETACP.EXE UCX V4.1-12J
Problem:
1. The UCX SHOW DEVICE command sometimes hangs. As a
result, the customer shut down UCX and brought it up
again. Upon doing this once, the system crashed.
2. At setup, select() should properly sense and return if
the socket has OOB data pending. While reception of OOB
data causes an active select() to terminate, active
OOB data does not cause a new select() to terminate.
Solution:
1. The cause of the hang is most likely that the UCX$BGDRIVER,
in responding to the UCX SHOW DEVICE command, is perusing
the I/O database without holding the I/O database MUTEX.
As a result, there is a remote possibility that the I/O
database might change while it is being searched. This
could have unpredictable results. The way to resolve
this problem is to simply request this MUTEX before the
operation begins, then release it when the search
is finished. This solution should relieve the user's need to
shutdown UCX in similar circumstances.
The crash that occurred after bringing up UCX was the
result of a resource problem in OpenVMS that left UCX
in an inconsistent state. A correction for this problem
requires a major rework of UCX initialization and is
planned for a future release. For the present, it is
recommended that frequent stopping and starting of UCX
be avoided.
2. OOB data does not appear as data queued to the socket's
MBUFs, and the read() code fails to clear the RCVATMARK
condition when the OOB data is returned to the user.
Hence, the check added in ECO C is not correct and the
previous code, while it will cause the select() to return,
may not have an OOB present.
The change will actually check the TCP context to see if
an OOB is present instead of trusting RCVATMARK. This is
a correction at one place in the driver, and the correction
to the read() code will be made for V4.1 and beyond.

UCX$INETACP.EXE UCX V4.1-12K
Problem:
A crash can occur in the IN_CKSUM routine with an access
violation. This problem is triggered by the receipt of a
technically illegal, highly fragmented ping request datagram,
probably from a Windows NT or a Windows 95 system. The
problem with the datagram is that when it is reassembled
with its IP header, it is longer than 65535 bytes -- the
longest length expressable in the 16 bits of the length
field of the IP header.
Solution:
In the ip_reass routine, fragmented packets are reassembled
without looking at the total length of the datagram.
To resolve the problem, if this length exceeds 65535,
the datagram will be discarded after incrementing the
ips_fragdropped counter by the number of fragments in the
datagram.

UCX$INETACP.EXE UCX V4.1-12L
Problem:
Incoming RSH connections sometimes hang.
Solution:
In the INETACP_GET_USER_INFO routine, the data from
the incoming RSH connection is parsed for information as to
the error port, the user name, command to execute, and so on.
If enough data has not yet arrived, a READATTN AST is set
to send a wake-up notification when new data arrives and then
causes the process to go into sleep. An error in setting up
the AST request created a timing window wherein the process
might go to sleep forever.
References:
Several reports.
ECO M 8-Nov-1996 Alpha and VAX
Image:
UCX$INETACP.EXE UCX V4.1-12M
Problem:
The correction in ECO D, above, was incomplete. Although it
prevented the service counter from growing when active
services were disabled, it also led in some cases to the
counter being decremented past zero. For example, disabling
the FTP service while one FTP connection was the only
activity on the system would result in the service counter
showing up as 65535 (-1, formatted as an unsigned word).
Following such underflow, no further connections for any
service are accepted.
Solution:
When decrementing the global service counter at service
disable time, set a flag in the BG UCB so that the counter
will not be decremented again later, when the device-socket
is deleted. To provide additional protection against any
such problems, always check that the value of the
service counter is non-zero before decrementing it.

Problems:
1. The UCX$INETACP process slowly loses AST count.
2. A system crash can occur in INET_GET_IRP with the INETCB
pointer as zero.
Solutions:
1. The cause of problem is that if an incoming RSH
connection specifies an error connection, and during
the processing of the specified RSH command data is
written over the error connection, the ACP loses track
of a READ ATTN AST that it had requested on the error
connection. The solution is to provide cleanup in
the INET_SELECT_REMOVE_UCB routine. This routine looks
at every UCB that is about to disappear. If it sees a
dangling READATTN AST on the socket associated with the UCB,
the routine removes it and returns the AST quota to its owner.
2. This is a synchronization problem in that UCX is being
brought down and residual PWIP activity results in a call
to INET_GET_IRP. The solution is to include a test for the
existence of the INETCB before using a pointer to it and
have the routine return an error if the test fails.

Problems:
1. A system crash (VAX only) may occur with a Reserved
Operand Fault during the execution of a CMPD
(Compare D_Floating) instruction.
2. A system crash may occur in the arpioctl routine
during reference to the variable arpoint, which is zero.
Solutions:
1. In INET_IN_OUT.MAR, there are two CMPD instructions
that, depending on the data they are comparing, might
cause a system crash. To resolve the problem, substitute
2 CMPL instructions for the offending instruction.
2. The arptable is allocated and the variable arpoint is
set to point to the arptable when the first external
interface is configured. If UCX is started and the
configuration database has no interfaces defined, it
may enter code that assumes that arpoint contains a
valid value. To resolve this problem, the code explicitly
tests for the possibility of a zero arpoint wherever that
is possible, and exits gracefully in that case.

Problem:
IP datagram fragments that have the DF bit set are
being ignored.
Solutions:
An IP datagram that has the DF bit set is incorrectly
assumed to NOT be a fragment. Instead, it was dropped
because no attempt was made to reassemble it and its
associated fragments into a complete datagram. The
assumption that the DF bit implies that a datagram is
not a fragment is no longer made.

Problem:
System crash, INVEXCEPTN, reassembling a fragmented
UDP datagram directed to a PATHWORKS socket.
Solution:
This problem is most likely due to a PWIP
problem, although the exact cause has not been found.
However, the crash is triggered by the receipt of a
fragmented UDP datagram, a rare event in normal
circumstances, that is then passed up to PWIP where
some data is being corrupted.
A change was made to eliminate the possibility
of passing fragmented datagrams to PWIP. This was done
by allocating adequate space to accommodate the
fragmented datagram and then copying the fragments
into a contiguous datagram.

Problem:
SSRVEXCEPT, on OpenVMS V7.x, when

Solution:
The problem was a failure to take 64-bit
addresses into account when returning the
user data to the user buffer. For 64-bit
systems, all data buffer descriptors are
normal to 64 bits.
However, in routine, INET_SORECEIVE_IMMEDIATE,
the descriptor was treated as if it were a 32-bit
descriptor. As a result, the high 32 bits
of the length were picked up and used it as if
they were the address of the user buffer.

Deallocate the VCRP(s) containing the ICMP
message, once the size check shows that the
first fragment is too small.
Reference:

Problem:
ICMP Timestamp Reply messages are sent using
a non-standard time value, but it is not marked
as such by setting the high-order bit.
Solution:
Set the high-order bit in the time value. It is
not possible at this time to send a standard value,
because the UCX kernel has no knowledge of Universal
Time, nor does it know the local timezone (which
would be required to calculate Universal Time).
Also correct the algorithm that was producing
a number of seconds 10 times too high.
References:

Problem:
The system crashed when issuing UCX SET NOINTER on
a system that had no physical interface attached
but had one configured.
Solution:
Crash occurred in shutting VCI ports but at the
time there was no VCIB for ARP, yet it was assumed
that there would be one. The correction was to explicitly
test for the existence of the ARP VCIB before using
its supposed address.

Solution:
Check for this condition before adding data to the VCR.
Reference:

Problem:
A crash occurred while processing a RARP request on VAX received
via the ARP VCI port.
Solution:
Routine ARPINPUT was returning a bad value. This return

never process RARP requests received via the ARP VCI port.
To resolve the partial RARP support, IF_ETHER_VMS.C has been
disabled.

Problems:
1. System crashed on a write to a BG device when P2 parameter
(user buffer length) specified a negative value.
2. When loading a proxy database of over 2048 entries,
certain entries became disabled.
Solutions:
1. Lengths of user buffers were not being properly
validated and as a result, the negative value length
was misinterpreted as a large positive number.
The correction was to properly validate this length,
limiting lengths to 64K-1 bytes.
Lengths greater than this and lengths less than zero
now cause the I/O request to be terminated with
an SS$_IVBUFLEN status.
2. An error in the definition of the MOVCL3 macro, which
did not properly account for overlapped moves, led to
corruption of the proxy database. The macro was modified
(INET_MACROS.MAR) and INETACP_CREPROC.MAR, where the macro
is invoked, was modified to correct branch destination problems
that arose with the new larger macro.

Problem:
1. System crashed; call to panic from SBDROP when
inconsistent data is left in the receive socket
buffer.
2. System crashed soon after boot on OpenVMS V7.1 Alpha
with per thread code.
Solution:
1. The problem arose in routine INET_SORECEIVE_ATOMIC,
when: a) data arrives on a UDP or raw IP socket while
un-synchronized in INET_MOVIO_TO_USER, and b)
the user buffer is smaller than the datagram, which
implies that the software does not consume the entire received
datagram and calls SBDROPRECORD. The correction
is to refresh R7, the pointer to the next datagram,
after resynchronizing.
2. UCX was inadvertently clearing an IRP field via a
CLRQ IRP$L_ACTION instruction, assuming (without
an explicit ASSUME invocation) that IRP$L_ARG1 was
in the next longword. For V7.0 of OpenVMS Alpha, this
assumption is no longer true, and the per thread
code uses this field that was being cleared. The
solution was to replace all instances of the CLRQ
IRP$L_ACTION instruction with the sequence:
CLRL IRP$L_ACTION
CLRL IRP$L_ARG1

Solution:

when the packet cannot be decompressed due to noise on the
line. When this situation occurred, the VCRP that contained the
packet was lost. The correction was to deallocate the VCRP when
the situationn occurs.

Problem:
IP multicast support was compromised in ECO W.

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.

Problems:
1. System crash in sbappend, called from
SOSEND_LOOPBACK.
2. Large mbufs leak.
Solution:
1. The cause of the crash is an apparent timing window.
In the recent past, the socket, for which we are
processing a transmit request, was paired with
another socket on this host. It was determined that it
was going to use optimized "loopback" logic at that
time. However, before it used the optimized "loopback"
logic, it gave up synchronization (i.e. lowered IPL) and
copied data from the user space into system buffers.
By the time it regained synchronization (raised IPL), the
paired socket was gone along with a pointer to it. The
socket used this now zero pointer and crashed.
The solution was to test for the existence of this
pointer after we re-synchronize. If it is no longer
there, then we simply deallocated the buffer chain that
we allocated to hold the user data, then returned.
This correction went into routine SOSEND_LOOPBACK.
2. In both INET_SOSEND_ATOMIC and INET_SOSEND_STREAM, error
paths were found that did not deallocate partial
allocations of mbufs. As a result, over time, it was
possible to lose mbufs. The solution was to add cleanup
code to these error paths.

Solution:
This problem resulted from a build problem
wherein LIB$GET_EF was being included in object
form rather than being called in LIBRTL.

Problem:
gethostbyname() incorrectly errors when AFR is enabled.
Alignment faults appear from inside gethostbyname.
Solution:
Fixing the source of the alignment faults would likely
require modifying the database format, which is not feasible
to do in an ECO and could be very risky. (Alignment faults
are only a performance issue, their occurrence should not
break any functionality.) Rather, we corrected the malformed
code to properly revert the LIB$SIG_TO_RET exception handler
in ucx$gethostbyname() prior to its calling into the
UCX$ACCESS_SHR.EXE library where the alignment faults
occur.

Problem:
An outbound TELNET device stoped working if unsolicited
input was received from the network.
Solution:
Set UCB$M_TT_NOLOGINS in UCB$W_DEVSTS to dismiss
unsolicited terminal input, leaving the device in a useful
state. Sense UCB$V_TEL_OUTBOUND in TN$RLOGIN_TIMER and
dismiss the disconnect.
Reference:
CFS.42083
Problem:
Output escape sequences are incorrect when function keys
are held down.
Solution:
Limit the number of outstanding characters in the local
buffer to half the buffer's size. This solution prevents local
overflow and limits the number of outstanding bytes against
the remote host.
Reference:
CFS.3895
Problem:
Applications performing I/O against an outbound TELNET UCB
did not know that the connection was lost.
Solution:
After connection loss, outbound TELNET sessions are still
capable of processing I/O operations even though nothing
happens. When the connection is broken, the application
is notified with SS$_HANGUP *if and only if* there are IRPs
pending against the UCB. If no IRPs are queued, the
application is not notified. In addition, any applications
that begin I/O after the connection is broken do not get
any error even though their data goes unprocessed.
To solve this problem, the device is turned OFFLINE after
the class driver is notified of a disconnection from the
network. This action will reject any I/O operations that occur
after the connection has been broken.
Reference:

Problem:

Problem:
A proxy login could be circumvented by sending unsolicited
data through the socket before LOGINOUT had a chance to
run. All logins are expected to be under the control of
the TNDRIVER but did not appear to be.
Solution:
When creating the TN device, set UCB$M_JOB in UCB$x_DEVSTS.
This makes the terminal driver believe that a login is in
progress so it discards the data and echoes a BELL. When
RLOGIN PROXY succeeds in the INETACP, the appropriate
automatic login occurs as expected. If the proxy check
fails (i.e., there is no valid proxy for this connection),
the normal login mechanism clears UCB$M_JOB before telling the
terminal driver to start the login.

Image:
UCX$TNDRIVER.EXE UCX V4.1-12F
Problem:
System crashed in OpenVMS routine EXE$TIMEOUT
while servicing a corrupt fork and wait queue.
Solution:
The problem occurred because of several factors, the most
important of which 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
re-defined to be bit 10 in V6.2.
The TNDRIVER distributed for all VAX platforms uses the
old definition. For Alpha platforms running OpenVMS V6.2,
the TNDRIVER built for V6.1 uses the old definition.
The result is that the wrong bit is being tested on systems
where the definitions are not synchronized.
The solution was to devise a new test of the condition
that works on all platforms.

Solution:
A variable in routine getChan() was incorrectly

corrupted. This problem went undetected until the
latest release of PATHWORKS. With older versions,
conditions were such that the routine was never entered
simultaneously. However, the new release of PATHWORKS
has a different set of calls into PWIP and the problem was
uncovered. The solution was to make the variable a normal

Problems:
BOOTP responded with incorrect IP address in the case of
more than 1 Ethernet systems.
Solutions:
Modified get_iproute() function. Pass network mask
of the iptarget to get_iproute(). Isolate subnet
of the iptarget by Anding iptarget with it's network
mask. Scan the routing table for a routing record
that matches subnet. Check for default route. If
it is not a default route, check to determine if it is a
host route. If not, check to see if it is
a network route.

Problems:
1. Concurrent downloads do not work.
2. Concurrent transfers did not work correctly.
3. On slower systems, the TFTP would not work
correctly when it initially starts up.
Solutions:
1. FileByteCount updates have been corrected.
2. The loop that does the concurrent transfers was
missing a statement to go to the next transfer.
Once corrected, everything started working.
3. Change the scheduling mechanism. Now new tasks are
appended to the list so that they are served FIFO.
The algorithm checks the timeout and if less than
minimum, it doesn't start another transfer to the same
client.

commands.
2. Wildcarded PUTs did not pass the target specification.
3. The PUT/FDL command failed if the filename included
a version (such is the case with PUT/FDL *.*;*).
4. Verbose messages were displayed by COPY/FTP when not
asked for.
5. Multiline responses could hang the client.
6. Improper handling of the target specification occurred
when wildcarding files.
7. RECV creates files named ".;".
Solutions:
1. Treat all commands that are not read from the

2. Add another parameter to wldcrd_put_process() to pass
the information.
3. Merge the "fdl" name modification into the type field
of the file specification; don't just append it to
the name.
4. Remove the unconditional display of the reply status.
5. Ensure that FTP client adheres to RFC 959's definition
of multiline response mode.
6. Treat the target specification has the directory specification

UCX$FTP.EXE UCX V4.1-12E
Problems:
1. Prompting was not working when mget-ing or mput-ing
files; e.g. answering 'y' caused all subsequent files
to be copied without any further prompting. When
multicharacter replies (e.g.: "Yes"") were typed in,
each character was interpreted as a separate answer.
2. "Literal" wildcard characters and multiple dots in
remote file specs did not work correctly when GETing
and PUTing files.
3. Wildcard substitution in target specification did not work as
intended (problems with get and copy /FTP).
4. Copy /FTP caused an access violation by performing an unnecessary
CWD /.
5. /INPUT files were opened with write access, as shown
by a privilege error generated when the protection code
of the file did not allow write access.
6. There were a number of reported problems with processing
remote and local OpenVMS logical names in file specifications when
PUT/GETing files or using copy /FTP.
7. In non-VMS-Plus mode, parseable remote names resulted in
incorrect local file names (e.g.: the name of the temp
file used to store the NLST results).
Solutions:
1. Changed wildcard_[get,put]_process() to use a local copy
of cnfrmflg (tcnfrm), rather than permanently altering
the global. Increased the buffer size used for prompting.
This corrects reading 'extra' reply characters if multiple
character answers are typed in.
2. Corrected recv_data() to always call ConvertFilenameToVMS().
Corrected a number of subtle problems in
ConvertFilenameToVMS(). Added new macro ftp_isvalidfnamec_().
- Changed FTP$GET() in ftp$client_cmds.c to call
wldcrd_get_process() only if "wild chars" found,
_and_ (parse) [i.e., globbing].
- Changed FTP$PUT() in ftp$client_cmds.c to allow
wildcard characters in the remote filename, if globbing
(i.e. wildcard expansion) is off.
3. Corrected wildcard expansion in wldcrd_get_process(). If
the local file spec contained a wild card, the entire
remote specification, including the node, device, and directory
was substituted from the wildcard onward. Now every remote
file specification is SYS$PARSED with syntax check option, and
only the file extension and revision number are used as
substitutes for the wild card(s).
4. In the DCL_Copy_Command() function, checking [length-1]
on a zero length string resulted in checking the byte
BEFORE the char string's starting address. About 10
lines of code was rewritten.
5. Corrected freopen() on /input file to use "r" instead
of "r+".
6. Changed FTP$GET() to always SYS$PARSE() with syntax check
only.
7. In wldcrd_get_process() use the RMS 'name' block attached
to file_fab when SYS$PARSE -ing NOT the one attached to
the local fab. Corrected bug in same where remote file names
containing wildcard characters caused subsequent files
to get an incorrect name. Corrected problem where the
user could not specify the target name of files containing
wild card characters.

2. Double /incorrect messages observed when PUTing a local,
locked file.
3. USER xxx yyy (where xxx is username and yyy is password) no longer
worked in /input command files.
Solutions:
1. Reworked the DCL_Copy_Command() function to enable
the use FTP/copy with non-Open VMS servers. Note that
non-OpenVMS directory specifications do have to be enclosed
in double quotation marks.
2. Added an extra SYS$PARSE in wldcrd_get_process() when
parsing remote to local file spec. Made minor changes to
getreply() to ensure the software always returns a status.
Added an 'early' sys$open attempt in wldcrd_put_process(), and
FTP$PUT() to do an early open of the local file so that
locked file is detected, prevents the sending of the
STOR command, opening a data channel, etc. on such files.
3. Enhanced login_prompt() so that it can deal with USER
xxx yyy passed on the same line in an /input file, while
preserving all conceivable other legacy behaviors (with
or without the USER keyword, username / password on the
same, or separate lines).

2. Lines in directory listings are terminated
incorrectly.
3. UNIX-formatted specifications are not translated
correctly.
4. Latent problem with anonymous access determined
from code review.
5. Auditing does not show actual file specifications;
it shows only what the user specified.
6. Problems with rmd() [delete directory]
specifications.
7. Problems with mkd() [create directory]
specifications.
8. Correct misspellings.
9. Several operations return errors but do not tell
why the operation failed.
10. STOU (store unique) creates bizarre file names
that are not unique for the given time period.
11. Loss of channels and mishandling of file

12. The "SITE HELP" command generates a multiline
response even if disabled.
13. When wildcarding against the server and either a
different directory or a search list or rooted
directory is used, operations fail.
14. Possible stack corruption caused by an
asynchronous QIO with an IOSB on the routine
stack; the routine has exited.
15. Peculiar handling of the directory specified to

18. Various DELETE deficiencies.
19. Correct login failures with certain passwords.
20. Sites that have a large number of FTPC processes
experience FTPD hangs.
21. Problems with exitmsg().
Solutions:
1. Add support for a network access string.
2. Terminate output lines with NVT (),
not just \n ().
3. Replace the broken UnixToVms() routine and include
a status return.
4. Change `AnonymousUser' flag to be an int instead
of a short; the handling was incorrect.
5. Move auditing into lower level routines where the
information is now available.
6. Change rmd() to use RMS to perform the operations;
RMS specs are now fully supported.
7. Change mkd() to use RMS to perform the operations;
RMS specs are now fully supported.
8. Corrected spelling of several messages.
9. Implement RFC 959 multiline responses. This can
be defeated by either specifying a hyphen (`-')
as the first character of the password (per RFC
959) or setting the logical name
UCX$FTPD_MULTILINE_DISABLE.
10. Use the RMS maximize version flag.
11. Perform the RMS $PARSE and $SEARCH operations and
pass a FAB around, instead of a name. FTPC now
has three FABS and uses a maximum of three
channels.
12. Correct the "SITE HELP" command, which violates
RFC 959's definition of multiline responses
concerning if they are enabled or disabled.
13. Expand the file names properly to ensure that
the files are accessible once their names have
been returned. Rooted directories, search lists,
and third-party node, device and directory
strings now work properly.
14. Remove the IOSB because the code does not check it.
15. Change CWD to use RMS to $PARSE and establish
the default directory properly.
16. Change routine check_filetype() to return an
exit status.
17. Perform the conversion properly, paying close
attention to the quoted areas of the file
specification strings.
18. Allow DELETE to use the multiline response
formats. Show what you deleted and what you
could not delete and why (if multiline enabled).
19. The password and password2 buffers were being
mistreated and any that contained a null byte
caused password verification to fail.
20. Increase the MAX_SESSIONS to produce a larger

Problems :
1. Entering a user name such as "ANONYMOUS "
(with an extra space) would bypass anonymous logging.
2. Code review spotted a problem with reading the
extended logging logical name.
3. There was a quota problem with passive sockets.
4. Error code 550 was sent to the client when
reporting a successful file deletion.
5. Deleting a locked file caused the UCX$FTPC
process to crash.
6. A number of problems were observed with logging
errors. Extra characters at the end of the message
and missing separators were seen. Some errors were
not logged.
7. Deleting multiple (wildcard-selected) files caused
the client to hang if multiline responses were
disabled. In such case, the server would not send
any status or error messages to the client,
and the client would wait for a reply until it
timed out.
8. A code review uncovered several errors in
ftp$server_ftpc.
9. An access violation occurred when 'mput'ing a locked file.
This error was traced to attempting to clean up a resource
that had not been allocated.
Solutions:
1. Changed function user() to be less sensitive to
spaces surrounding the user name when comparing
to ANONYMOUS.
2. Corrected reading of extlog in main(). The pointer
was not de-referenced after reading the logical name.
3. In createpasvsock(), the socket receive quota
was not set, so a socket QIO would block forever
when done with IO$M_LOCKBUF. A setsockopt() call,
to set the quota like it is done in createdatasock().
For easier maintenance, a new function
ftp_setwindowsize() was created to perform this,
called from both create*sock() functions.
4. In function dele(), code 250 was substituted for
the 550.
5. In function dele(), error_text is now used instead
of the uninitialized global ErrorMessage.
6. LogErrorBuffer is now properly initialized,
and errors are always logged.
- Multiple exit paths in dele() were eliminated from
the while(TRUE) loop.
- The software no longer uses ReplyBuffer for building
status/error messages.
- Included a period (.) in sendermsg() after the last
item on the format list of sprintf when composing
the mailbox message. UCX$FTPD was looking for this
terminating period when parsing the message, and
messages ended up improperly terminated if the period
was omitted at the end of the message.
- Ensured that messages never send blank strings by setting
any blank strings to "-". This solution prevents the UCX$FTPD's
sscanf() reading message components into the wrong variable.
The software checks for NULL pointers passed in, sending
a dash "-" instead. Replaced all " "-s with NULL -s in
sendermsg() calls.
7. New logic was added in dele() to trace if
any messages were sent. If not, the final (summary)
message is forced.
8. In SetupAnonymousDirectories, GetErrorMessage() now
assigns the return value to ErrorMessage.
- In translate_error_message() the format string
%X08X" was replaced by the correct ""%.8X".
- Eliminated all malloc() and calloc() calls inside
functions, as recommended before, EXCEPT the
VMS-Plus /Linked List related ones. Instead of
allocating memory inside functions, the softrware uses
static var-s.
- In sendermsg() and postrply(), changed QIO to QIOW.
It seemed dangerous to use a local buffer with
asynch IO.
- In appe_vms_plus_bin changed QIO to QIOW, where the
software was executing a SYS$WRITE of the buffer just
read, without synchronization.
- In appe_normal_bin changed QIO to QIOW, where the software
was executing a SYS$PUT of the buffer just read,
without synchronization.
9. In all appe*, send* and recv* file functions, added
flags to prevent de-allocating/cleaning
up a resource if it has not been successfully allocated.

Problems:
1. Several reported problems when attempting to read
read-only files.
2. Problems and access violations with anonymous FTP logging.
3. Random access violations when 'GET'ing files with
insufficient privileges.
4. When listing directories, a cr-lf is inserted
after the file name if it is a long name. This
confuses some 'automated' clients.
5. Code review discovered several problems in
ftp$server_ftpd.c.
Solutions:
1. Changed check_filetype() to use SYS$ASSIGN as it
did several versions ago. The combination of flags
used with SYS$OPEN had an unexpected side effect of
an implied 'write' privilege. This caused 'get'
attempts to fail when the user had read-only privileges
on the file.
2. In a number of places, corrected the
write_anonymous_log() call, where an incorrect
argument number was specified and /or parameters
were passed in the wrong order. This was causing
failures in logging some anonymous transactions
such as get and put and apparent access violations.
Wherever write_anonymous_log() is called, a
distinct status variable tracks logging
related errors, and an error is not returned from
the function that called it if the log call fails.
3. In send_vms_plus_bin(), after the
fdlgenerate_in_mem() call, the translate_error_code()
call was made with error_text instead of &error_text.
4. Added a new variable 'glo_lineup_dir' and /sys logical name
UCX$FTPD_DIR_CR_DISABLED to govern the insertion
of cr-lf -s in directory listings where the name of
the file is too long.
5. Changed QIO to QIOW wherever a local iosb was used.
Changed name of global variable 'status' to
'glo_status'. In some functions, where a local
'status' was not declared, the global variable was
used, resulting in side effects.
Declared local 'status' variables in functions that did
not have one.
In pass(), took out the extraneous/unnecessary
FAILURE(status) processing in the initial
user_anonymous processing.

Problem:
The code was changed to use a fixed value of
32767 for FAB$W_USZ in send_normal_bin() and
send_vms_plus_bin(). In cases where block I/O
was being performed (all VMS-Plus cases, and
IMAGE non-VMS Plus), this caused bytes to be
lost, since block I/O is always performed on
a block boundary. In particular, with 32767,
the last byte of the 32K was lost, every 32K.
Solution:
The code was changed to use 32768 instead. This
has been written as 64*512 to emphasize the fact
that it should be a multiple of 512 bytes.

Problems:
When the NFS server does data conversion, the apparent size of
the file changes. Some clients, including DIGITAL UNIX,
use their cached unconverted size instead of the more
recently supplied converted size. Thus the file appears
to be missing its tail or have extra bytes at the end.
Solution:
If enabled by modus_operandi bit ppda$v_fake_mtime,
deduct a microsecond from mtime of unconverted files.
This solution provokes clients sensitive to unstable file size
(such as DUNIX) to invalidate the data cache on a subsequent
getattr. The unconverted size is then replaced with the
converted size on the reread.

Problems:
1. When an attempt is made to create a temporary relay
file with a NULL byte, everything after the NULL
byte in one of the data records is ignored. The NULL
byte is being interpreted by fprintf as EOR. By
changing from fprintf to fwrite, a specified buffer
length can be written to the temporary file.
2. All threads being handled by the TNS hangs when one
thread is waiting for a connection to a remote printer.
When an attempt is made to connect to the remote printer
and the connection cannot be established (i.e., the
printer is turned off), all queues being handled by
that TNS process will hang. The connection attempt
was made with a sync Q but has now been changed to
make the connection attempt with an async QIO with
an AST.
Solutions:
1. Use fwrite() instead of fprintf() when writing to the
relay temporary file.
2. In open_socket, issue a non-blocking QIO specifying AST
open_socket_ast().

Problem:
With UCX as the LPD client, a problem exists when large
jobs are printed:
1. UCX-LPD-client opens the TCP-connection (to port 515)
to the LPD server.
2. UCX-LPD-client sends /02/0A.
3. UCX-LPD-client does a complete read of the print file
(on its own disk) to get the file size (and probably to
copy it to the spool area).
4. UCX-LPD-client sends a /03 filesize filename/0A.
5. UCX-LPD-client sends the contents of the data file and
the control file.
Step 3 consumes a large amount of time in the case of large files.
Some LPD server implementations (e.g., LEXmark printer)
cannot live with this long pause in an open TCP-connection and
they disconnect due to an idle timeout. Sometimes this value
can be configured. In an installation with many LEXmark
printers, the value of 10 seconds cannot be changed.
Solution:
The order of handling has been changed. Connection to the
LPD server (when file size is available) is not made until
after the file is read.

Problem:
A job stays in the "processing" state in the

Solution:
An approximated simulation showed that the symbiont is
trying to read data from the socket using recv(). If
no data is available at the socket, the receive call
waits for data to arrive and will wait forever. To
solve the problem, a select() is used to check if the
socket is ready to be read. The timeout value is taken
from the logical name UCX$LPD_RETRY_INTERVAL.

Problem:
A print job that is sent from one UNIX system through

Solution:
The receive job subcommand 'receive data file'
is constructed by using the file name that is the result
of FIND_FILE on the spool directory. The file name is a
valid OpenVMS name that does not match the file name
specified in the control file. The solution is
to open the control file, extract the parameter of the
'H' card, and use it to construct the file name.

spool directof a remote printer on aan OpenVMS/Alpha V7.1 system.
UCX$LPRSETUP dosn't create spool directory on Alpha running
OpenVMS V7.1 and UCX V4.2.
Solution:
The mkdir() 3rd uic arg bug in VMS 7.x has been reported to
the DECC folks (DECC Notes Conference #2659).
In the interim, it seems viable to workaround the mkdir() by
changing UCX$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!

Problem:
If not instructed to delete a mail message that
has been read by the POP client, the POP server
always copies it to the MAIL folder. For some uses
of POP it would be better to simply leave mail that
has been read by a POP client, but not deleted, in
the NEWMAIL folder.
Solution:
UCX POP can now be configured to leave mail that
has been read but not deleted by the POP client
in the NEWMAIL folder or to move it to the MAIL
folder. This is done with the "Leave in NEWMAIL"
configuration option. The "Leave in NEWMAIL"
option is useful in a situation like this:
Users at XYZCorp have PCs at home with which they
dial in to the office. They also have PCs in their
offices. The office PCs are to be the users
authoritative mail reposistory where they keep
mail in various folders. However, the users still
want to read mail on their home PCs. To do this,
they configure their home PC's POP client with the
"Leave on server" option so that the POP client does not
delete the mail from the server. They configure the
office PC's POP client with "Delete from server".
Finally, the POP server itself is configured with
"Leave in NEWMAIL". Now, when mail is read from
home, it is left on the server in the NEWMAIL folder.
When mail is next read from the PC at the office it
is picked up from the NEWMAIL folder (including any
messages already read at home since they were left
in the NEWMAIL folder), and the mail is deleted.
Note that the Netscape POP client, when configured
to "Leave on server", uses the UIDL command to keep
track of which mail it has already fetched from the
POP server. This has the benefit of not fetching
the same mail more than once when mail is left in
the NEWMAIL folder.
To configure this option do:
$ DEFINE/SYSTEM UCX$POP_LEAVE_IN_NEWMAIL 1
Note that at this time, the "Leave in NEWMAIL"
feature is not configurable on a user-by-user basis.

OpenVMS callable mail reads the entire mail message.
If the process does not have enough memory, OpenVMS
callable mail returns MAIL-W-NOMOREREC.
The solution was to detect this condition and
send a mail message back to the recipient with instructions
to ask the system administrator to increase the
server account's page file quota.

UCX$POP_SERVER.EXE UCX V4.1-12E
Problem:
VMSmail API was returning an incorrect number of records
for a mail message that was in it's NEWMAIL folder. The POP sever
uses this number to loop thru calls to mail$message_get() to get
each line record) of the message. Because the length of the
message was incorrectly given as one more than the actual length,
the call to mail$message_get() to get the last message line
resulted in the MAIL-W-NOMOREREC error.
Solution:
Documents a situation where VMSmail reported 120-
record message, but the actual external mail file contained only
119 records as read thru the MAIL$M_RECMODE (record-at-a-time)
method. Tolerate this offf-by-one accounting assuming it's
identical to the prior HACK ALERT, which handles a similar
situation with messages read via the MAIL$_MESSAGE_BUFFER method.

ECO G 5-MAY-1998 Alpha and VAX

UCX$POP_SERVER.EXE UCX V4.1-12G
Problem:
PMDF (another vendor's) mail client was translating
single-quote (') characters in From: addresses into "\s" before
wrapping them with SMTP%"...". This renders the address as
illegal from RFC822 standpoint, so SMTP and POP did not recognize
this as a proper "SMTP" From address, failing one of the three
conditions necessary for ignore_mail11_headers operation. While
single-quote is a legal character for an SMTP address, embedded
backslashes are not.
Solution:
If POP's patch_from_line() call to SMTP's build_path_from()
routine fails with UCX$_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. Customer is
expected to notify the third party vendor to get the root cause
problem in the mail client fixed.

Problem:
UCX$SMTP_MAILSHR.EXE fails with an access violaiton

Solution:
When reading a record from the mail file, determine
the longest record length in the file and read in
that length. If record length exceeds 1000 bytes, write
out multiple 1000 byte lines in the outgoing mail
message. Also inform the user that this is happening
with the following message:
%UCX-I-SMTP_LINEWRAP, Line contains more then 1000
bytes, splitting into multiple lines.
This change requires a change to UCX$MSG.EXE to
display the SMTP_LINEWRAP information code.
Problem:
The command ANALYZE MAIL/REPAIR results in -JBC-F-MISREQPAR
following by -SYSTEM-F_SSFAIL errors.
Upon detecting that a job in the SMTP queue does not
have a file associated with the job, SMTP tries to
delete the job from the SMTP queue. However, the item
list to the SNDJBCW was not set up correctly.
Solution:
Define the item list to the SNDJBCW system service
locally within the function that deletes the job
from the SMTP queue. Also, set up the item list
correctly.

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 acceptible
solution because none of the provided source code in either
RPCXDR or PCNFSD uses either int64 or unit664. Therefore, these
typedefs are only used in customer applications. If a customer
application is currently using the miss-defined 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:

RCP-CONHST. In routine rcp$get_rsocket, the
address or hostname is passed to ucx$inet_addr,
which tries to make it a network value or
returns -1 on error. The code checked for <0
rather than -1 explicitly. Since the ipaddr
variable was declared as an int, anything of
the form xx.xx.xx.128 or above would be returned
as a negative number.
Solution:
Declare ipaddr as unsigned long, and compare it
to (unsigned long) -1 to see if ucx$inet_addr
failed.

Problem:
This corrected a problem with a 7-minute, 9-second
incorrect offset bug. This bug was assumed to be
corrected in an earlier patch (and ECO6), but one
occurrence of the bug still existed at that time.
Solution:
There was an area of manually doing 64-bit OpenVMS
time arithmetic that had a problem with the carry bit.
The UCX team originally corrected this through casting the
variables involved, but unfortunately also included a
correction for this same area when porting over new code from
elsewhere. So it was corrected twice, which resulted in
recreating the bug. The casting change was removed, so
that the change of subtracting the carry bit when
required still exists.

Problem:
NTP: times not adjusted in 5 node mixed cluster.
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.
