-------------------------------------------------------------------------------
PREVIOUSLY UNDOCUMENTED BEHAVIOR:
-------------------------------------------------------------------------------
1. Additional information.
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
mis-interpreted 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$_IVBUFLEN status.
References:
See the diagram on p. 3-4 of the "UCX System Services
and C Socket Programming Guide". "Transfer Size" gets
a 16-bit field (because VMS QIO interface only provides
for a 16-bit return value on the actual number of bytes
read in the IOSB structure).
2. Recommended documentation changes.
Fix documentation in UCX System Service & C Socket Programming
Guide.
On p. 6-11 which documents listen(), change:
If a connection request arrives with the queue full (more
than backlog connection requests pending), the client
receives an error with an errno of ECONNREFUSED.
to:
If a connection request arrives with the queue full (more
than backlog connection requests pending), the request is
ignored so that retries inherent in TCP may succeed. If
the backlog has not cleared by the time TCP times out, the
connect() will fail with ETIMEDOUT.
On p. 4-55 which documents QIO IO$_SETMODE/IO$_SETCHAR, change:
If more connections are received than have been specified,
the 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.
PTR 70-5-773
Alternate name 1: CFS-55406
Alternate name 2: MGO103148
Abstract: backlog parameter is ignored in a call to listen()
Remark: The documentation is incorrect; UCX is behaving properly.
UCX adheres to the prototypical Berkeley implementation in this
regard. In tcp_input_vms.c::tcp_input(), incoming segments on a
listen socket are handled by creating an embryonic socket for
the later accept() via sonewconn():
if (so->so_options & SO_ACCEPTCONN) {
/* remember the listener socket */
so0 = so ;
so = sonewconn(so);
if (so == 0)
goto drop;
sonewconn() enforces the listen queue backlog using the standard
Berkeley algorithm of 1+1.5*backlog, returning 0 when this backlog
is exceeded:
sonewconn(head)
{
:
if (head->so_qlen + head->so_q0len > 3 * head->so_qlimit / 2)
goto bad;
:
bad:
return ((struct socket *)0);
}
When this occurs, tcp_input() goes to drop, which silently drops
the incoming SYN. It does NOT issue a RST response.
However, the UCX documentation for listen(), in the UCX System
Service & C Socket Programming Guide indeed contradicts this
behavior by indicating that "If a connection request arrives with
the queue full [...] the client receives an error with an errno of
ECONNREFUSED." This would only make sense if TCP responded to such
connection requests with a RST.
The UCX documentation appears to have been derived from the old
Berkeley listen(2) man page. It turns out that ECONNREFUSED is
only applicable to AF_UNIX domain sockets, not AF_INET (UCX only
supports AF_INET). More recent listen(2) man pages clarify this;
Solaris 2.6 provides a better description:
If a connection request arrives with the queue full, the
client will receive an error with an indication of ECONNRE-
FUSED for AF_UNIX sockets. If the underlying protocol sup-
ports retransmission, the connection request may be ignored
so that retries may succeed. For AF_INET sockets, the tcp
will retry the connection. If the backlog is not cleared by
the time the tcp times out, the connect will fail with
ETIMEDOUT.
This issue is also discussed in Stevens "Unix Network Programming,
2nd ed.", and explains the rationale why responding with RST is not
appropriate:
If the queues are full when a client SYN arrives, TCP ignores the
arriving SYN (pp. 930-931 of TCPv2), it does not send an RST.
This is because the condition is considered temporary, and the
client TCP will retransmit its SYN, hopefully finding room on the
queue in the near future. If the server TCP were to send an RST,
the client's connect() would immediately return an error, forcing
the application to handle this condition, instead of letting
TCP's normal retransmission take over. Also, the client could not
differentiate between an RST in response to a SYN meaning "there
is no server at this port" versus "there is a server at this port
but its queues are full".
Posix.1g allows either behavior: ignoring the new SYN or
responding to the new SYN with an RST. Historically, all
Berkeley-derived implementations have ignored the new SYN.
UCX 4.x is a Berkeley-derived implemenation.
Compiled and ran test client and server provided by customer. One
instance of server was started on VMS UCX system. Eight instances
of clients were started within seconds of each other on a Unix
system. The first client was accepted by the server, and it tied
the server up for 120 seconds doing its business. During this time,
the second and third clients were queued to the backlog properly
(per the BSD backlog algorithm which queues up to 1+1.5*backlog
connections), and were processed once the first client exited
normally. The 4th-8th clients were not queued; their TCP
retransmits timed out within the 75-second connection-
establishment timeout (in UCX this is the TCP DROP_TIMER) before
the server finished handling the first client. On timeout, these
clients all exited when their connect() calls returned ETIMEDOUT.
This is the expected behavior of a Berkeley-derived TCP stack.

Corrections for DIGITAL TCP/IP Services V4.2 INSTALL Images
---------------------------------------------------------------------------
---------------------------------------------------------------------------
ECO 1 updates:
--------------
ECO A 13-MAR-1998 Alpha and VAX
Image:
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.
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$SNMP_SHUTDOWN without
stopping and restarting UCX.
Reference:
Internal testing.
ECO B 3-MAR-1998 Alpha and VAX
Problem/Solution:
Updated UCX$BINDSETUP command procedure.
Included UCX$NFSSETUP command procedure.
Sources:
UCX$NFSSETUP.COM V4.2-21
UCX$NFSSETUP_HELP_CLIENT.DAT V4.2-21
UCX$NFSSETUP_HELP_SERVER.DAT V4.2-21
UCX$NFSSETUP_HELP_MAIN.DAT V4.2-21
UCX$BINDSETUP.COM V4.2-21
UCX$BINDSETUP_HELP.TXT V4.2-21
6-MAR-1998 Alpha and VAX
Problem/Solution:
Prior versions of this file would complain about UCX$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$INET_DOMAIN
logical names. Previous versions would uppercase the fully
qualified host name.
Sources:
SYS$NET_SERVICES_UCX.COM V4.2-21
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:
IP Multicast support was compromised in V4.1 ECO W. 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.

Problem:

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

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

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 re-defined 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 V6.1 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
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 unit64.
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.

UCX$LPRSETUP V4.1 ECO 2 to ECO 6 DOES NOT create the
spool directof a remote printer on an OpenVMS/AXP V7.1 system.
UCX$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:
The POP server could not process mail messages with more

Solution:
Changed code to bypass the limit by looking at OpenVMS
callable mail's internal buffer for the message.
Problem:
When trying to read large mail messages, the POP
server hangs and issues a MAIL-W-NOMOREREC error message
to the log file.
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.
The solution is to detect this condition and
send a mail message back to the recipient telling
to asking the system administrator to increase the
POP server account's page file quota, thereby
correcting the problem.

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)

identical to the prior HACK ALERT, which handles a similar
situation with messages read via the MAIL$_MESSAGE_BUFFER method.

UCX$POP_SERVER.EXE UCX V4.2-21C
Problem:
PMDF (another vendor's) mail client was translating
single-quote (') characters in From: addresses into "\s" before
wrapping them with SMTP%"...". This renders the address as
illegal from RFC822 standpoint, so SMTP and POP did not recognize
this as a proper "SMTP" From address, failing one of the three
conditions necessary for ignore_mail11_headers operation. While
single-quote is a legal character for an SMTP address, embedded
backslashes are not.
Solution:
If POP's patch_from_line() call to SMTP's build_path_from()
routine fails with UCX$_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:
SMTP receiver is not including any 'From' DOMAIN header
information.
Solution:
Retro fit change from the v5/v6 code:
smtp_recv.c and smtp_recv_serv.c :
Add "from domain" clause into the Received: header we tack
onto incoming messages. This corresponds to PTR 30-1-625

UCX V4.1 E8 SMTP, Inbound mail causing a %SYSTEM-F-ACCVIO on
the UCX$SMTP_RECEIVER server, which does not deliver the mail.
Solution:
The correction is add logic to fetch the MAXIMUM NUBER OF
INTERFACES and to use that value in the buffer size
calculation. The definition of INET$C_MAX_IFNETS was added to
inetdef.h. Delete the "comment" part of the from address.

UCX$RPCXDR_SHR.EXE UCX V4.2-21A
Problem:
IEEE double precision results in 'Server can't
decode argument' from a UCX client.
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.

Sources:

Images:
None. (actually most all of the .exe files change, but the types.h
file is all that will be patched.)
The file types.h belongs in the system directory:
SYS$SYSROOT:[000000.SYSCOMMON.UCX$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 acceptible
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 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.

Images:
UCX$NTPD.EXE UCX V4.2-21A
Problem:
NTP: times not adjusted in 5 node mixed cluster.
Solution:
Added an option similar to unix NTP which allows the correction
of any time difference, including times greater than the
maximum aperture. The flag is not set by default, which means
that if the time difference is too large (around 5.3 hours or
so) then the following message will appear in the log
file: seconds is too large (set clock manually or set correct-
any) To set the option, CORRECT-ANY is added to the UCX$NTP.CONF
file which after doing the filtering and finding the
difference to be too large, it will reset the time.
