- snmp_pe core dumps when receiving unusual SNMP packets

- snmp_pe does not support the "no_auth_trap" directive in snmp_pe.conf.

- When running the snmpCollect daemon of Polycenter Netview 4.1, but could
  occur when any random SNMP application formats packets unusually (not
  necessarily improperly).
PROBLEM:       (Patch ID: OSF350-019)          (Case ID: QAR 33027)
********
snmp_pe reads configuration information from snmpd.conf. One of the directives 
that may be contained in it is "no_auth_trap". When active, snmp_pe should NOT 
send an authenticationFailure trap when it receives an SNMP request containing 
an unknown community name.

The bug is that it DOES send the trap even when no_auth_trap is active.

PROBLEM:       (Patch ID: OSF350-019)          (No problem reports yet)
********
This bug was found during FT of Polycenter Netview V4.1, it has not been reported
by a customer yet.  But the bug exists in all released versions of snmp_pe.

It is triggered by running the snmpCollect daemon of PNV 4.1, but could
conceivably occur when any random SNMP application formats packets unusually 
(not necessarily improperly).

A characteristic stack trace:

PXG Family 2D Graphics Card Panic Correction:
The system panics during the initialization of the X server (which usually
occurs at the end of system startup when xdm is started).
PROBLEM:	(Patch ID: OSF350-034)	(HPXQ86C85,HPXQ87A4A,HPXQ85059)
********
On any Digital UNIX V3.2C system with a PXG-family graphics card, the system 
panics during the initialization of the X server (which usually occurs at the 
end of system startup when xdm is started).  

Here is a sample stack trace:

   0 boot() ["../../../../src/kernel/arch/alpha/machdep.c":1735]
   1 panic() ["../../../../src/kernel/bsd/subr_prf.c":757]

  13 syscall() ["../../../../src/kernel/arch/alpha/syscall_trap.c":519]
  14 _Xsyscall() ["../../../../src/kernel/arch/alpha/locore.s":1094]

The PXG-family consists of the following graphics options:

	PMAG-DA         PXG
	PMAG-FA         PXG Turbo
	PMAG-EA         PXG+
	PMAGB-F         PXG Turbo+

The PXG family of graphics options can be used with Digital UNIX V3.2C for 
displaying 2D graphics only.  Support for the PXG family has been retired in 
Open3D V3.0 which runs on Digital UNIX V3.2C.  Earlier versions of Open3D which 
support the PXG family are not supported on Digital UNIX V3.2C.

Using high-speed modems with LAT: application may fail because tty speed 
is set to 0.
PROBLEM:	(Patch ID: OSF350-039)		(CLD HPAQ6396E,SPR HPAQ56EF8)
********
During a LAT session on a Digital UNIX system, using a high-speed modem
connected to a LAT server, some applications may fail to execute correctly
because the LAT subsystem has set the tty speed (as reported by stty) to 0.

This patch changes this behavior, so any attempt to set the speed higher
than 38400 bps results in the speed not being changed. stty should report
9600 as the tty speed.

LSM rootdg Configuration Correction:

PROBLEM:  ( MCPM8935A   QAR 36456 )    	( Patch ID: OSF350-053 )
********
The problem will be seen if root/swap encapsulation or mirroring fails and the 
rootdg diskgroup has been tuned to have a privlen greater than 512 sectors. The
problem only occurs when the configuration database in the rootdg diskgroup has
records that will not fit in 512 sectors. Hence only large LSM configuration 
will see this problem. 

The messages on the console during the encapsulation will show 

   "volassist: No more space in disk group configuration"

The system can panic when a disk is in a RAID set and is mislabelled.
PROBLEM:	(Patch ID: OSF350-066)		(HPAQ917D5)
********
The system can panic when a disk is in a RAID set and is mislabelled.

The system will panic with a stack trace similar to:
>  0 boot
   1 panic
   2 advfs_sad
   3 bs_cow_pg
   4 bs_cow

The error log will contain messages similar to:
        advfs I/O error: setId 0x2fc0af89.00086de0.2.8051
                         tag 0x0000137d.8006u page 336
            vd 1  blk 4110448  blkCnt 32
            write error = 28

The disk being complained about is in a RAID set, and is disklabeled as a rz 
disk and not an re disk.

The thing to note about the message is that the block number (4110448 in the
example) is very close to the end of the disk.

This panic is caused by the RAID controller appropriating some blocks at the
end of the disk for its own use.  Advfs, however, thinks it can write the
entire disk because of the incorrect disklabel.  The panic happens because
the RAID controller returns EIO when Advfs tries to write in the reserved
area.

This is a user error caused by incorrect labelling of the disk.  This patch
causes mount_advfs fail to mount the domain read-write and issue an error
message rather than have the system panic later.

When illegal user arguments are passed to the semop() system call, such that
exactly none of the requested operations work, the system call code continues
in a path that corrupts memory by depositing a PID number in areas beyond
the semaphore structures allocated memory.  When this occurs, the 16-byte
elements in kmembuckets[0] are the target of the corruption.
PROBLEM 1:	(Patch ID: OSF350-069)		(Case ID: HPXQA3279)
**********
When illegal user arguments are passed to the semop() system call, such that
exactly none of the requested operations work, the system call code continues
in a path that corrupts memory by depositing a PID number in areas beyond
the semaphore structure's allocated memory.  When this occurs, the 16-byte
elements in kmembuckets[0] are the target of the corruption.

Due to the unpredictable nature of the consequences of the memory corruption,
there is no obvious stack trace that would point to this bug.  However, here
are 3 actual traces that were caused by this bug:

This correction fixes file corruption on a Digital Unix NFS fileserver serving

originally seen when the only nfs client was an OS/2 PC.

If you observe server corruption and can bypass that corruption by setting the 
kernel global variable 'kudp_usedrc' to zero, then you need this patch.

Do not consider turning off duplicate record checking (drc) as a solution.

Corrects a card lockup problem using the ATM IP convergence module.
PROBLEM:	(Case ID: HPXQC2E60, QAR 42749 ) 	(Patch ID: OSF350-115)
********
Card lockup problem using the ATM IP convergence module.

How to recognize the problem:

   In the kern.log file you can see messages similar to:

   Dec 19 11:06:47 bcaryf03 vmunix: received 144 bytes for non-existent VC 50

   and if you have set up a simple test between two systems using a ping over
   the ATM interface, you will see that the signalling between VC's which have
   been sending and receiving throughout the test will suddenly stop receiving
   packets.  The VC's will continue to be able to send packets.

How to reproduce the problem:

   Setup two nodes A and B connected through a FORE switch and an ATM IP
   PVC between the two.

   From node B, issue the ping command over ATM IP. (leave the ping command
   running)

  On node A, remove the ATM IP PVC which is receiving the ping using the command
   "atmconfig -pvc driver=lta0 vpi=0 vci=50"

   In the kern.log file you will see a message like:
   Dec 19 11:06:47 bcaryf03 vmunix: received 144 bytes for non-existent VC 50

   and the output of an atmconfig vclist long will show you that the signalling
   between VC's sending and receiving throughout the test will suddenly stop
   receiving packets.

PROBLEM:	(QAR 43371)			(Patch ID: OSF350-121)
********
On Digital Alpha VME 2100 Systems with EV4.5 or EV5 processors with the embedded
VIP/VIC64 VME bus adapter, the system may crash with console messages such as:

   halted CPU 0
   CPU 1 is not halted
   halt code = 7
   machine check while in PAL mode
   PC = 18624

The PC may be different, and the halt code may be 6.

This is caused by the VME adapter's bus support code probing memory for 
accessibility at a low IPL, which allows conflicting operations to occur during 
the probe.  

This patch fixes the problem by performing the memory probe at a higher IPL and,
during the probe, disabling some interrupts that can be caused by the probe.

********
System panics with a machine check, a VME adapter error occurs with an 
indication that a PCI Target abort occurred, or data corruption occurs 
transfering data between VME devices and system memory.

These errors can be caused by the dma_map_load kernel interface failing to 
return the correct value to indicate an error.  

This patch corrects the dma_map_load kernel interface so that it correctly 
returns an error value.

PROBLEM:	(QAR 39481)			(Patch ID: OSF350-121)

Master Block Transfer hardware DMA performance is poor on the embedded VIP/VIC64
VME bus of Digital Alpha VME 2100 and AXPVME systems.  This is caused by 
incurring multiple "process dispatch latency" times between DMA segments of

This patch improves DMA performance by reducing the number of "process dispatch 
latencies" incurred to one.  "Process dispatch latency" is defined as the time 
between an interrupt service interface signaling a thread to execute and the 
thread actually executing.

Fixes a problem where the LAT subsystem limits the number of remote LAT nodes

PROBLEM:	( CLD HPAQ285B1, SPR STLQB0253 ) (Patch ID: OSF350-155)
********
This patch fixes a problem where the LAT subsystem limits the number of remote
LAT nodes on a Digital UNIX system to a maximum of 100. The Digital UNIX 
subsystem keeps information about remote nodes which have broadcasted service
service announcement messages. On a busy local are netowrk with many LAT
devices, this maximum limit could be reached. Users may see an error message 
such as "insufficent node resources" when trying to connect to the Digital UNIX 
system from a terminal server or other LAT host. With this patch to latcp 
installed, the LAT subsystem sets no limit on the maximum number of remote 
nodes that it stores information about.

The mold daemon component of the Common Agent leaks memory when running with the
DEC SNA PeerServer product.
PROBLEM:  ( IPMT Case CFS.27284 ) (Patch ID: OSF350-169)
******** 
The DEC SNA PeerServer product instantiates a new (protocol engine) daemon that
connects to the mold daemon component of the Common Agent each time an incoming
request is received by the DEC SNA PeerServer product from the network. 

The PeerServer product can handle hundreds of requests per minute, each time
starting and then stopping its protocol engine daemon that connects to the mold 
daemon.  The mold daemon does not clean up the socket connection that gets 
created each time the PeerServer creates a new connection to the mold, leaking 
several thousand bytes of virtual memory per connection, plus leaves the socket 
connection dangling.

Over time, the mold component can consume all available virtual memory, causing 
unpredictable results and system performance degradation.  Ultimately, the 
customer is forced to stop and restart the PeerServer product, which is not 
acceptable to the customer, as this process is very resource intensive and can
take many minutes to complete.

Errors may get logged in the /var/adm/syslog.dated/<date>/daemon.log file, 
including messages similar to these (t21mcd and t21mad are DEC SNA PeerServer
daemon components; mold is a Common Agent daemon component):

PROBLEM:	(STLQB2393)		(Patch ID: OSF350-107)
********
After installation and configuration of a DW300 token ring option, the system 
becomes unstable on boot, resulting in varied system panics.  

The symptom can be avoided by unplugging the token ring cable.

Fixed other problems which could result in varied panics or corruption:

 o Fix IFF_PROMISC mode support.
 o Fix mbuf corruption on receive path.
 o Fix starting of error log thread on multiple units.
 o Disable printing of some commonly occuring ring events.
 o TMS380C25 and later set ring speed in the SIFACL register.
 o Broadcast address wasn't accepted in ioctl.
 o Reference counts were not kept on functional address additions
   which result in clearing a functional address before all users
   referencing it had disappeared.
 o Bit reversing can occur twice when a transmit gets put back on
   the if_queue when the devices xmit rings fill up.
 o Open retries d o not clear when the interface is shut off.
 o Added shared interrupt support (for PCI only).
 o Fixed startup problem where tw o MAC_OPEN commands could be

This patch corrects the following:

- Fixes a problem on ASE systems where LSM volumes remain in SYNC state 
  when no volume resync or volplex att command is running. This results 
  in performance degradation.
PROBLEM:	(QAR 39624)	(Patch ID: OSF350-213-1)
********
This patch fixes a problem on ASE systems where LSM volumes remain
in SYNC state when no volume resync or volplex att command is running.
This results in performance degradation.

The volprint command shows that the state of the volume is SYNC, as in:

 # volprint -g oracledg -vl oracle
    Volume:     oracle
    info:       len=8379551
    type:       usetype=fsgen
    state:      state=SYNC kernel=ENABLED
    assoc:      plexes=oracle-01,oracle-02
    policies:   read=ROUND exceptions=GEN_DET_SPARSE
    flags:      open rwback (offset=0) writecopy writeback
    logging:    type=BLKNO loglen=1 serial=0/5 (enabled)
    device:     minor=8 bdev=40/8 cdev=40/8 path=/dev/vol/oracledg/oracle
    perms:      user=root group=system mode=0600

However, ps shows no volresync or volplex att command executing, as:

    # ps -e -o command | egrep 'volume|volplex'
    #

The problem can be reproduced with the following scenario:

    1) Create a volume by giving the two plexes in the same volmake.
       Thus the volume will contain the two plexes before it is started

    2) Ensure the volume uses plexes having a log sub-disk, even if the
       volume log_type is not using the log sub-disks.

    3) Once the volume is started by the 'volume start' command, 
       abort the copy process by either:

                a) Shutting down the system.
                b) Deporting the disk group.
                c) Killing the volume start process.
                d) Restarting the ASE service utilizing that volume.
                e) Relocating the ASE service utilizing that volume.

    Now the volume will stay in SYNC state across reboots
    and ASE restart and stop/start sequences.

PROBLEM:  ( ZPOB30186 / QAR 46022 ) (Patch ID: OSF350-221)
********
This patch fixes a halt/restart problem with the mfa driver ESP self-test.
If the DEMFA interface halts, self-tests are performed.  The mfareset routine 
contained a bug which prevented the interface from restarting after the halt.

The DEMFA interface may also halt due to it's inability to allocate (malloc) 
memory for it's buffers.  The correction for the malloc problem is contained
in the MANDATORY PATCH.  

Typical error messages in the /var/adm/messages file will include:

	xpd1 = 0x183f8000, xpd2 = 0x0, xpud = 0x8c5d001c

The 'c' in the XPST indicates that the ESP special test failed.

    1) When a system is running C2 security and an account is locked
       because of too many illegal login attempts.

    2) When making a second attempt to mount an NFS file system
       that failed to mount during the first attempt.

-  This patch also fixes a problem where pcnfsd does not generate audit events 
   for successful pcnfsd authorizations (auth_event "succeed" events).

PROBLEM:  ( QAR39830 ) (Patch ID: OSF350-231)

This patch fixes a problem where the System V getdirentries() system call did 
not correctly calculate the number of entries in a directory inode when 
accessing the /dev/fd file system. The problem resulted in the readdir() 
function returning erroneous directory entries when used on the /dev/fd file 
system and also caused error messages to be produced by the ksh builtin dir 
command when used on /dev/fd.

Error messages such as the following are typical:

stat: /dev/fd/ptyq9: No such file or directory
stat: /dev/fd/ttyq9: No such file or directory
stat: /dev/fd/ptyqa: No such file or directory
stat: /dev/fd/ttyqa: No such file or directory

The problem can be reproduced by using the System V ksh builtin dir command 
on /dev/fd.

This patch fixes a problem where an attribute had been set to "read only"
and the built-in command typeset (eg. typeset +r <attr>) could not set
it back (unset) to "read/write" status.

If the built-in command 'typeset +r <attr>' is entered after an attribute has
been set to 'read-only' status (eg. typeset -r attr=val), the following message 
is displayed:
	
	ksh: <attr>: is read only.

Enter 'typeset -r <attr=val>' and then enter 'typeset +r <attr>'.  As a result,
an error message will be issued.

PROBLEM:  ( USG-01932 ) 	(Patch ID: OSF350-171)
********
This patch fixes a problem in which a system running ksh as the login shell
would wipe out the previous contents of the history file (for example, 
.sh_history) and put the new information in the file.  This occurred after a 
user logged into an ULTRIX system from an OSF/1 system using the telnet or 
rlogin commands.

On an associated Ultrix machine, an official patch for cld HPAQ6E7B needs to
be installed when it uses the NFS mounted filesystem from the UNIX machine.

Do the following to reproduce this problem:

1. Setup a new account on an OSF/1 V3.2C
  with /bin/ksh as the login SHELL and with the home
   directory NFS mounted from an ULTRIX system.

2. Rlogin into the OSF/1 system from an ULTRIX system
   and issue a few commands.  Make sure "history" shows the
   commands you just issued. Cat ".sh_history" just to sanity
   check what's in there; logout.

3. Rlogin into the ULTRIX system and issue a few commands.  Then
   cat ".sh_history" file and see whether the previous commands
   get written from the OSF/1 system or the ULTRIX system.
   You can see new commands from the ULTRIX system get written into the
   .sh_history file, but the commands from the OSF/1 system get wiped out.

4. Rlogin into the OSF/1 system again from the ULTRIX
   system. Cat ".sh_history" to ensure that the ULTRIX commands still
   exist, then enter a few commands.
   Finally, cat ".sh_history" file and notice that the previous
   ULTRIX commands get wiped out.

Add the time out options -t nnn & -T to the "showmount" command.
PROBLEM:  (HPXQ36487/QAR 46954) (Patch ID: OSF350-240)
********
If the "showmount -e host" command does not receive the requested export
list from the specified host within 25 seconds, it will issue the
following error message: 

    Can't do Exports rpc: RPC: Timed out

The most likely cause for receiving this error is if the specified host
system is running a 3rd party product that provides its own file system
interface _AND_ if accessing that file system is slow (perhaps on the
first reference to the file system) _AND_ if a sufficient number of such
file systems are exported so that 'mountd' takes a long time to read and
verify the list of exported file systems. 

Generally speaking, 'mountd' is able to read and verify its export list
in less than a second or a few seconds worst case for a very large list.
However, if conditions do exist that would cause 'showmount' to issue
the above error, then this version of 'showmount' provides options that
will allow the time out value to be changed. 

    -t nnn specifies the time out value in seconds.

    -T specifies an infinite time out.

This patch fixes a problem in which PATHWORKS client does not
see all the files in a directory when the directory is an NFS
mounted OpenVMS UCX exported directory.

On an Digital UNIX system a nfs mount to a VMS-UCX system exists.
For this mount point a share is setup in Pathworks.

PCs connect to this share and don't see all files of this
VMS directory, some files and subdirectories are missing.
But on the pc it is possible to type the files which are
not seen or it is possible to do a cd to the directory
which is not seen. In Pathworks the user has all permissions
for that share so he can read all files, he can delete the
file but it is not possible to write a file to this
directory.
The same files which are seen on DOS are shown in
PWADMIN - Shared Resources - Permit!
Examples:
1. It is not possible to see the file x.txt.
If x.txt is renamed to a.txt then the file is seen in the
directory listing.
2. It is not possible to copy a file to this share (drive X)
COPY C:\CONFIG.SYS X: returns the error
File not found - X:CONFIG.SYS
0 Files copied
---------------
There is no problem in the directory listing if ls command
is executed on Digital UNIX. Besides ls -al displays root as
owner for every file.

Allows system managers to both set and obtain quotas for users and groups which
are numeric when using the edquota, vedquota, quota and vquota programs. It
also provides new options to allow them to specify userids and groupids.
PROBLEM:  ( HPXQ87072, QAR 46521 ) (Patch ID: OSF350-274)
********
This patch allows system managers to both set and obtain quotas
for users and groups which are numeric when using the edquota, vedquota,
quota and vquota programs. It also provides new options to allow them to
specify userids and groupids.

In the past, when the input to these commands was a numeric username or
groupname, the commands would either report that the name couldn't be found,
or would interpret it as the wrong user or group
(when the name coincidentally matched a valid userid or groupid).

For circumstances where the user wishes to specify userid or groupid the
-U and -G options have been added.

This correction also extends the edquota and vedquota prototype
option to allow convenient use of names and ids. In the past a numeric
argument to the "-p" option was incorrectly considered an id, not a name.
Now, the argument to "-p" will always refer to a name while the argument
to the new option "-P" will refer to an id.

Examples

To apply the quotas of user1 to user2, specifying both by their names:
    edquota -p user1name user2name

To apply the quotas of user1 (specified by id), to user2 (specified by id):
    edquota -P user1id -U user2id

Also, note that new versions of the message catalogue files are issued
for each of the programs. These must be updated only if they are on the
system.

PROBLEM:  (QAR 36520, QAR 48372) (Patch ID: OSF350-287)
********
Some valid programs compiled with ieee mode may receive a floating-point
exception even though they should run to completion. The problem occurs
because the floating-point exception handler is too strict when attempting
to enforce trap shadow rules (SRM 4.7.6.1). The following C program fails
when executed on a system with a DECchip 21064. 

Compile the following program with the command:
cc -migrate -g -ieee_with_inexact t.c -o t

        f( int dum, ... ) {
        }

        main() {
            int ii = 50;
            f( 42,
                (float)ii / 100,
                (float)ii / 100,
                (float)ii / 100 );

(for example, when a structure is passed as an entity rather than as a pointer).
This led to an improper instruction sequence where a register value was
dereferenced as an address pointer, when in fact the register was a temp and
had just been corrupted by a previous function call which generated the error 
message
        "Segmentation fault (core dumped)".

SUPERSEDES PATCHES:     OSF350-233 (233.00)

This patch corrects the following:

- A problem that occurs on multi-processor machines in which the at command
  causes extra batch jobs to be executed. Sometimes temporary files are created
  and not removed, causing the queue limit to be exceeded.

- Fixes a problem in which cron jobs will not run if there is an unfinished job
  in another queue. This problem occurs even if the queue for the job is empty.
PROBLEM:	(HPAQ40CCC)	(Patch ID: OSF350-233)
********
This patch fixes a problem in which cron jobs will not run if there is an 
unfinished job in another queue. This problem occurs even if the queue for 
the job is empty.

Typically, a long job is the only job scheduled from cron.  After that job 
terminates, another cron job starts executing.  This results in several 
"MAXRUN procs reached" messages getting displayed to the error
log. The /var/adm/cron/FIFO file, which should only exist while jobs remain
queued, remains around much longer than expected.

This problem can be reproduced by running the following test.  To do this, 
you need three windows running the following commands:
 truss -p <CRON PID>    You might want to script
 tail -f /var/cron/log    the truss and batch_two.ksh
 batch_two.ksh     processes.

The batch_two.ksh file is:
#!/bin/ksh
 echo "sleep 9999" | batch
 integer COUNT=1
 while [ COUNT -lt 60 ] ; do
  echo "sleep 15" | batch
  (( COUNT = COUNT + 1 ))
 done

 (
 sleep 222
 echo "sleep 700" | at -qr now +1 minute
 echo "sleep 750" | at -qr now +1 minute
 echo "sleep 800" | at -qs now +1 minute
 echo "sleep 14" | batch
 ) &

 integer STOP=0 PS
 while [ $STOP -eq 0 ] ; do
  atq | tee /tmp/atq.out
  ps -ef|grep sleep | tee /tmp/ps.out
  ls -l /etc/cron.d/FIFO
  date
  PS=`cat /tmp/ps.out | wc -l`
  AT=`cat /tmp/atq.out`
  [ $PS -le 1 -a "$AT" = "no files in queue." ] && STOP=1 || sleep 10
 done
 echo "$0 finished."
 rm -f /tmp/atq.out /tmp/ps.out


        integer STOP=0 PS
 while [ $STOP -eq 0 ] ; do
  atq | tee /tmp/atq.out
  ps -ef|grep sleep | tee /tmp/ps.out
  ls -l /etc/cron.d/FIFO
  date
  PS=`cat /tmp/ps.out | wc -l`
  AT=`cat /tmp/atq.out`
  [ $PS -le 1 -a "$AT" = "no files in queue." ] && STOP=1 || sleep 10
 done
 echo "$0 finished."
 rm -f /tmp/atq.out /tmp/ps.out

<end of ksh script>
       
The previous test shows that a long running job will prevent cron from
scheduling jobs from any queue until one of the following events occur:

 1) The long running job exits, or
 2) Cron exhausts the FIFO list of already completed jobs
    (one minute per job)

Either of these conditions may take a very long time.  For a long running job, 
such as a part14 report, it may be hours.  It could take cron a very long time 
to exhaust the FIFO list at one minute per job (200 completed jobs = 3.3 hours).

The intertesting part of the test occurs when the background sleep 222
completes and places the four new jobs in queues r, s, and b. These jobs will 
wait for a long time when they do not need to wait at all.

This patch adds the new resource printOnlyPrintables to dxterm which can
be used to suppress ANSI escape sequences when printing.

To enable the new resource (and tell dxterm to not send escape sequences
to the printer) start dxterm as follows:

    dxterm -xrm "*printOnlyPrintables: 1"

or add the following line to the dxterm resource file:

    DXterm.main.terminal.printOnlyPrintables: 1

Fixes a problem that causes the system to panic after creating a symbolic link

PROBLEM:	(HPAQ83C24)	(Patch ID: OSF350-297)
********
This patch fixes a problem that causes the system to panic after creating 
a symbolic link to the root file system ('/') and accessing it like a 
normal file.

For an AdvFS file system, the system will panic with the following error 
message:

	bs_bf_htop: invalid handle

For other file systems, the system will panic with the following error message:

       vrele:bad ref count


For 'bs_bf_htop: invalid handle' (AdvFS) a typical stack trace could 
look like:

PROBLEM:	(HPAQ88A35)	(Patch ID: OSF350-301)
********
This patch fixes a problem in which the ping command can time out
after invoking the "rcinet restart" command.

To reproduce the problem:

1) Run the tcpdump utility on the lan interface and filter on ICMP traffic.
2) Stop and restart internet services using the command "rcinet restart".
   You may have to restart services more than once to obtain an output
   similar to the following while invoking the ping command;

        10:25:50.802272 0.0.0.0 > 137.35.226.10: icmp: echo request
	10:25:51.802272 0.0.0.0 > 137.35.226.10: icmp: echo request
	10:25:52.802272 0.0.0.0 > 137.35.226.10: icmp: echo request
	10:25:53.802272 0.0.0.0 > 137.35.226.10: icmp: echo request

Notice the source field contains 0.0.0.0.  The destination cannot return
the ICMP echo reply to this address.  The ping command will timeout and
report 100% packet loss.  The ping command can fail for a local destination
as well as a remote host.

- Correct "siopintr: interrupt for non-initialized controller" boot error.

- Fixes a problem that occurs with the NCR 53C8XX driver (psiop) in which 
  the device may not appear to be on the SCSI bus. 
PROBLEM:	(QAR 36371)	(Patch ID: OSF350-030)
********
At boot, when probing the psiop driver, the system may continuously loop
generating the following error message:

    "siopintr: interrupt for non-initialized controller"

This error rarely occurs. Our test cases only encountered it when continuously
rebooting for 18+ hours. To cause the machine to reboot, the system usually
started a "shutdown -r now" as part of the bootup sequence


PROBLEM:        (49240)         (Patch ID: OSF350-302)
********
This patch fixes a problem that occurs with the NCR 53C8XX driver (psiop).
In rare cases when negotiating sync xfr rates, the driver may reject
the target's Synchronous Transfer Negotiation, even if the target replied
with a synchronous offset equal to zero, thereby implying asynchronous
transfers.  A device not expecting this behavior may not appear to be
connected to the system.

The RW531 Optical Jukebox, with Rev 0.37 firmware or later, does not
expect this behavior and will exhibit the symptoms of the optical disk
devices appearing on the SCSI bus, but not the changer devices.

In the above trace, the connection is rejected because the TOS (Type Of Service)
field contains an invalid value.  This problem can be avoided by using a
/etc/iptos file as noted in the man page.  However, the TOS field should never
have this invalid value and that is the reason for the patch.

SUPERSEDES PATCHES:	OSF350-002 (2.00),   OSF350-075 (75.00),
                        OSF350-261 (261.00)

This patch corrects the following:

- Stray interrupts which lock up the PCI bus and hang the system.

- Reseating disks in BA356 off P2SE would cause the slot to become inaccessible.

- All Alpha/PCI systems that support QLogic fail to boot when two or more tapes
  are installed on a QLogic/SCSI channel.

- Panics:
        o simple lock time limit exceeded
        o unable to restart Qlogic(LUN queue after abort)
        o simple_unlock: minimum spl violation

- "CAM_ERROR entry too large" messages.

- ASE: Qlogic driver returns incorrect status if the sim driver is unable to
  correctly respond to an Enable_Lun command from the peripheral driver.

- CAM errors when the target NVRAM parameters for either tagged queueing or
  disconnect privilege enable are disabled.

- Data transfer size of 16Mb results in no data transferred.

- Probe of isp fails intermittently during boot.


The following driver corrections require hardware changes to fully resolve
the noted problems:

- pcierror panic. These driver changes might help mitigate the occurrence of
  this panic. Complete solution of the problem will involve some changes in
  the Tlaser platform code.

- Bus Device Resets on narrow or wide SCSI devices. Complete solution of these
  problems requires both this modified driver and new Qlogic firmware
  (rev 2.10 or greater).

- Data corruption occurs on SCSI write transaction in response to a particular
  sequence of events on the PCI and SCSI bus. This driver change, in
  combination with rev 2.10 or greater Qlogic firmware, corrects the problem.

Intermittently, the probe of an isp will fail during a boot, and the system can
hang.  This happens maybe once in 20 system boots, so a workaround is to try 
the boot again.

This patch corrects the following:

- The terminal line characteristics for telnet with a modem were being reset
  to 7-bits/no-parity from 8-bits/no-parity.

- A problem where telnet dumps core if the USER environment variable is the
  last variable in the enviroment list.
PROBLEM:	(HPAQ26C0B, QAR 43433)	(Patch ID: OSF350-140)
********
The terminal line characteristics for telnet with a modem were being reset
to 7-bits/no-parity from 8-bits/no-parity.

How to recognize the problem:
If you have an application that requires you to specify 8 bits/no-parity 
for use with serial terminals and dial-in modems, telnet will override 
the setting giving you 7 bits/no-parity.  Check the terminal settings 
with the command stty -a.  

You typically would see the following:
parenb -parodd cs7 -cstopb hupcl cread -clocal  

when you really want:
-parenb -parodd cs8 -cstopb hupcl cread -clocal

SUPERSEDES PATCH:	OSF350-070 (70.00), OSF350-214 (214.00)

This is a MANDATORY patch for all machines containing the DECchip 21040-AA and
DECchip 21041-AA (TULIP) Ethernet chips.

This patch corrects the following:

- Under relatively rare and stressful conditions, the DE500-XA Fast Ethernet
  interface (tu) will stop receiving packets. This causes the interface to
  appear hung.

- Under certain relatively rare and stressful conditions, the DECchip 21040-AA
  and DECchip 21041-AA (TULIP) Ethernet chips will corrupt a transmit packet and
  compute/create the CRC per the corrupted data and send the corrupted packet.

- Under heavy system/bus loads, the default programming of the DECchip 21140-AA
  Fast Ethernet device (DE500), results in excessive framing errors.

- Under relatively rare and stressful conditions, the DE500-XA Fast Ethernet
  interface (tu) will stop receiving packets.

- Fixes a system panic, on a SMP system and tu interface, with error message:

If the user sending mail makes an error entering the address of the person
they are sending mail to, they will receive a mail message that contains both
the text of their mail and the error messages.

The error messages do not correctly describe the exact nature of the problem.

For example:

The "RCPT TO:" address line is entered as the user <tammy>
The "To:" address line is mistakenly entered as the user <"bozo>.

The error messages will be displayed as follows:

554 Unbalanced '<'
050 <tammy>... Connecting to  (local)...
554 <tammy>... Unbalanced '<'
554 <tammy>... Unbalanced '<'

  to the root directory.

- ftpd core dumps when using anonymous ftp with the ls commmand.

- A potential security vulnerability has been discovered, where under

PROBLEM:	( HPXQ917BA ) 		(Patch ID: OSF350-160)
********
This patch fixes a security issue in which a user using anonymous ftp could be
logged in to the root directory.

If the home directory of 'ftp' (used for anonymous ftp) does not exist, or
is otherwise inaccessible to the 'ftp' user, then a user logging in via
anonymous ftp is logged in with a home directory of '/'.

Arrange for the home directory of the 'ftp' user to be inaccessible (by
renaming it to something else, for instance), then from ftp try logging into
the system with anonymous ftp. If the login is successful and the user has
/ for their home directory, the bug exists.

This patch corrects the following:

- Fixes fsck operation where if fsck is run on a non-existent file system 
  or on a currently mounted file system, it returns a success status of zero.  
  It should return a non-zero status. 

- Fixes a problem in which the UFS property list can become corrupted.
PROBLEM:	(QAR 46424)	(Patch ID: OSF350-347-1)
********
This patch fixes a problem in which the UFS property list can become corrupted.

To reproduce this problem, complete the following steps:
1. Create a relatively large property value on a file.
2. Create another property value on the same file.
3. Change the property value created in Step 1 to a smaller value.
4. Run fsck with the -o flag.

The fsck command reports that the file system is corrupted and displays
the following error message:

	** Phase 1 - Check Blocks and Sizes
	PROPERTY LIST BLOCK CORRUPTED I=3
	CLEAR? [yn]

This patch corrects the following:

- Fixes a problem for TLI applications which make use of the t_accept library
  routine.  The secondary endpoint state is not being set correctly.

- Corrects a problem encountered by tli applications which do 
  an abort disconnect on an endpoint which was established as an orderly 
  release endpoint and leave the endpoint in an unexpected state.

NFS clients, specifically SUN NFS clients can't write files based on group

Given the following conditions:

 - A directory contained in an NFS file system with a protection code of 755.

 - A file contained in the directory with a protection code of 664.

 - The directory and the file have the same group ownership.

will have permission to modify the contents of the file.


PROBLEM:	(HPAQC854C, QAR 46335)	(Patch ID: OSF350-220)
********
This patch fixes a problem in which the nfsportmon command does not allow 
the root directory to be mounted from either a Solaris system or from 
an ULTRIX Version 4.2A system.

There is a program making it's way around the internet that allows 
non-priviledged users to mount filesystems, even if the NFS server 
is configured to only allow root users to mount (NONROOTMOUNTS=0 
in /etc/rc.config).  In order to protect against this, customers are 
using nfsportmon to enhance the check mechanism.  nfsportmon checks 
to make sure that file access requests were generated by the client kernel 
rather than a forged application.

However, with nfsportmon turned on, Sun Solaris clients cannot mount anything, 
even as root.

For example, if you have a Digital UNIX v3.2c nfs server, and
NONROOTMOUNTS=0 and nfsportmon is on, the root user on another Digital UNIX
system can mount exported directories fine, but the root user on a Solaris
system cannot.  The root user on a Solaris system gets the following error:

# mount sandpiper:/mnt /staff/ajs/mnt
nfs mount: sandpiper: NFS service not responding
nfs mount: retrying: /staff/ajs/mnt

With nfsportmon turned off, the directory mounts fine from Solaris.

In addition to Solaris clients failing, ULTRIX v4.2a clients also fail with
the same error.
                 

PROBLEM:	(CLD HPXQ9722E)	(Patch ID: OSF350-314)
********
This patch allows some third-party NFS v2 clients to experience 
a performance improvement.  Candidate applications are ones that 
perform read/write operations to a memory mapped file over NFS. 

NOTES: 

1) This patch must be enabled _BEFORE_ NFS is started because it needs 
to perform some configuration operations before client requests start arriving.

This why the dbx patch is to the /vmunix file and not to memory.  

If the patch is applied to memory, it will be ignored, since 
the initialization routine only runs when NFS is started. 

2) Affects NFS V2 only.  NFS v3 connections are unaffected.

3) Files that are only read or only written will not be affected.

4) The NFS Dup cache and NFS Write Gathering are disabled by this patch. 

To enable the patch, perform the following steps:

    % dbx -k /vmunix
    (dbx) patch stall_write_patch_enabled=1
    (dbx) quit
    % reboot


PROBLEM:	(CLD FNO100139)	(Patch ID: OSF350-382)

This patch corrects the following:

- Enhanced fix to the solockpair() routine; problem symptoms include
  kernel memory faults with sockets, mbufs and mblocks as well as hangs.
  Applications using sockets in a multi-threaded, multi-cpu environment can
  experience a number of lock violations with the socket structures.

- Fixes a problem in which packet filter programs do not receive packets 
  when the source is sending multicast packets on an Ethernet network.

- Fixes a problem in which network applications communicating to
  one of the host's own addresses, may hang, or receive the error message:

    no buffer space available

- System crashes with "Unaligned kernel space access from kernel mode"
  (Packetfilter unaligned access panic from ipintr).

- When writing packets using the packetfilter on FDDI, there are 14 bytes
  of corruption in the link layer header of the packet, so the packet appears
  corrupted on the FDDI ring.

- A "panic: lock_read: hierarchy violation in del_dealloc_stg" error occurs 
  when a socket lock is held by a UNIX domain while calling vrele().

- An SMP machine running a large number of web server daemons, for example,
  "ns-httpd" or "httpd", may experience an SMP race condition that will cause
  the system to panic.

- Improves the performance of the network on a system being used as a web
  server. There are additional tuneable parameters included to be used by the
  highly informed system admin.

- A user on a remote host can cause a Digital UNIX host to hang or panic.

- Fixes a problem in which the system panics when an interface is deleted.

- Provides a new tcp level socket option called TCP_NODELACK. This socket
  option allows a user to force an ack (acknowledge) after each received
  packet.

- Fixes a problem in which broadcast packets are received by a daemon listening
  to a port that is using both the INP_RECVDSTADDR and SO_REUSEPORT socket
  options. The packets were not being delivered to the listening daemon.

- Fixes a kernel memory fault panic that occurs on SMP platforms. The problem
  occurs when running the Unicenter product from Computer Associates in
  conjunction with Oracle software.

- Fixes a system panic caused by a Windows95 or WindowsNT system sending an
  illegal length ping ( ICMP ) packet.

- A kernel fix for network sockets left in FIN_WAIT_1 state forever.  This
  patch contains a "tunable" kernel parameter.  It is recommended that only
  experienced system administrators attempt to set this parameter from the
  default value.

- Fixes ICMP REDIRECTS.  When an ICMP REDIRECT is received, the routing table
  was updated properly, but the IP layer didn't use the new route information.

- Fixes a problem where a system attempts to ping a Digital UNIX system
  connected to a token ring network and the ping uses a message size that
  requires fragmentation.  The Digital UNIX system receiving the ping cannot
  respond.  The token ring driver displays the following error message
  to the console and resets the token ring adapter:

    List Error in transmit
PROBLEM:	(CLD HPAQ738E0)		(Patch ID: OSF350-041, OSF350-084)
********
System crashes with "Unaligned kernel space access from kernel mode".

The system uses the packetfilter option and "copyall" mode to receive
loopback packets sent via the packetfilter.  The crash shows an unaligned 
access (longword access attempt using a non-longword address) from ipintr.
The problem occurs whenever a packet larger than 170 bytes is written through 
the packetfilter and the packet is a loopback packet (destined for the local 
machine) or a broadcast packet (which gets copied to the local host).

Software packages which can trigger this include: Insignia "SoftWindows"
and LISP "OpenGenera" software from Symbolics, Inc.  Both of these packages 
use the packetfilter subsystem with the loopback feature and the "copyall" 
packetfilter flag.

The kernel stack trace looks like:

> 0 boot() ["../../../../src/kernel/arch/alpha/machdep.c":1620]

********
When writing packets using the packetfilter on FDDI, there are 14 bytes of 
corruption in the link layer header of the packet, so the packet appears 
corrupted on the FDDI ring.  This fix is to the FDDI/packet filter code for an 
erroneous write-side bcopy, which has been corrected.

This problem does not occur using Ethernet.  It is included here so that 
patch #1 does not get overwritten.  There is no impact (side effects, etc.) if 
this patch is installed when FDDI is not being used.

PROBLEM:	(QAR 45094)	(Patch ID: OSF350-158)
********
This patch improves the performance of the network on a system being used as a 
web server. There are additional tuneable parameters included to be used by the 
very knowledgeable system administrators.

	CAUTION: Only experienced network system administrators should
        be using these parameters to modify their system. Adverse effects
        may result. In-depth knowledge of the network and it’s workings 
        is required. 

        PLEASE DO give this to major customers running big systems as web
        servers. They will have the people who understand the features being
        provided.

TUNING

To tune the web server, the number of simultaneous socket connection requests
are limited by:

        somaxconn               Sets the maximum number of pending requests
                                allowed to wait on a listening socket.  The
                                default value in Digital UNIX V3.2 is 8.
                                This patch kit increases the default to 1024,
                                which matches the value in Digital UNIX V4.0.

        sominconn               Sets the minimum number of pending connections
                                allowed on a listening socket.  When a user
                                process calls listen with a backlog less
                                than sominconn, the backlog will be set to
                                sominconn.  sominconn overrides somaxconn.
                                The default value is 1.

The effectiveness of tuning these parameters can be monitored by
the sobacklog variables available in the kernel:

       sobacklog_hiwat         Tracks the maximum pending requests to any
                               socket.  The initial value is 0.

       sobacklog_drops         Tracks the number of drops exceeding the
                               socket set backlog limit.  The initial
                               value is 0.

       somaxconn_drops         Tracks the number of drops exceeding the
                               somaxconn limit.  When sominconn is larger
                               than somaxconn, tracks the number of drops
                               exceeding sominconn.  The initial value is 0.
                                                                        
TCP timer parameters also effect performance. Tuning the following
require some knowledge of the characteristics of the network.

        tcp_msl                 Sets the tcp maximum segment lifetime.
                                This is the maximum lifetime in half
                                seconds that a packet can be in transit
                                on the network.  This value, when doubled,
                                is the length of time a connection remains
                                in the TIME_WAIT state after a incoming
                                close request is processed.  The unit is
                                specified in 1/2 seconds, the initial
                                value is 60.

        tcp_rexmit_interval_min
                                Sets the minimum TCP retransmit interval.
                                For some WAN networks the default value may
                                be too short, causing unnecessary duplicate
                                packets to be sent.  The unit is specified
                                in 1/2 seconds, the initial value is 1.

        tcp_keepinit            This is the amount of time a partially
                                established connection will sit on the listen
                                queue before timing out (e.g. if a client
                                sends a SYN but never answers our SYN/ACK).
                                Partially established connections tie up slots
                                on the listen queue.  If the queue starts to
                                fill with connections in SYN_RCVD state,
                                tcp_keepinit can be decreased to make those
                                partial connects time out sooner.  This should
                                be used with caution, since there might be
                                legitimate clients that are taking a while
                                to respond to SYN/ACK.  The unit is specified
                                in 1/2 seconds, the default value is 150
                                (ie. 75 seconds).

The hashlist size for the TCP inpcb lookup table is regulated by:

        tcbhashsize             The number of hash buckets used for the
                                TCP connection table used in the kernel.
                                The initial value is 32.  For best results,
                                should be specified as a power of 2.

The hashlist size for the interface alias table is regulated by:

        inifaddr_hsize          The number of hash buckets used for the
                                interface alias table used in the kernel.
                               The initial value is 32.  For best results,
                                should be specified as a power of 2.

The maximum system assigned user port number is limited by:

        ipport_userreserved     The largest port number given to a user
                                process requesting a system-assigned port
                                (INADDR_ANY).  The default is 5000, which
                                allows 3975 ports to be assigned in the
                                range 1025-5000.  The maximum is value
                                is 65535.

This patch is a kernel fix for network sockets left in FIN_WAIT_1 state forever.

This patch contains a "tunable" kernel parameter.  It is recommended that
only experienced system administrators attempt to set this parameter from
the default value.

How to recognize this problem.

This is an example of the problem with tcpdump running in the background
listening on the destination ip address shown in the netstat output.

# netstat -An | grep 203.232.10.221
Active Internet connections
PCB      Proto Recv-Q Send-Q  Local Address      Foreign Address (state)

9418ef00 tcp        0    759  192.86.154.82.80   203.232.10.221.162

13:28:12.973072 www-2.us.oracle.com.80 > 203.232.10.221.1623: . 0:1(1) ack 1
win 33232

What is observed here is the destination is clearly dead.  The source is
sending an ACK to the destination looking for his ACK of our FIN.
This is commonly refered to as "persist mode".  A socket in this state will
never timeout and system resources associated with it will not be
released.

The new kernel modification to tcp_timer.o can be "tuned" by dbx'ing the
tcp_keepidle parameter on the system.  By default, this is set to 14400
1/2 seconds (2 hours).  It can be easily set to any value appropriate for
the system to "balance" the number of sockets in FIN_WAIT_1 state at any
time.  The system may always have some sockets in FIN_WAIT_1 as well as
CLOSE_WAIT, this is NORMAL.  What you don't want is a large number of sockets
in FIN_WAIT_1 forever.  It is not recommended that tcp_keepidle be set to
less than 5 minutes on the system.

Reference the man page to dbx for guidelines when using the dbx command.

The problem can be seen when a system attempts to ping a Digital UNIX system
connected to a token ring network and the ping uses a message size that

respond.  The token ring driver displays the following error message
to the console and resets the token ring adapter:

The problem occurs due to a queue full condition on the interface.

In an Available Server (ASE) or TruCluster environment, the daemons will
no longer be able to communicate with each other, and the asemgr utility

PROBLEM:	(MGO102810,QAR 49847)	(Patch ID: OSF350-384)
********
This patch is an enhanced fix to the solockpair() routine.  

This fix was needed because the routine was freeing a socket lock structure 
that was concurrently spun upon in lock_write().  Typical problem symptoms
include kernel memory faults with sockets, mbufs and mblocks as well as hangs.
Applications using sockets in a multi-threaded, multi-cpu environment can
experience a number of lock violations with the socket structures.

This patch is MANDATORY to install on all systems.  It will be effective
on Uniprocessor systems when lockmode debugging is invoked.

- Fixes a problem where the lpq command causes the program to crash
  (segmentation fault).

- Print jobs cause existing jobs to be deleted from the queue whenever the
  number of print queue entries exceeded 1000.

- Print jobs created within a short timeframe, for example within the same
  second, were not sorted by print jobs and timestamps.
PROBLEM:  ( HPXQ846D7 ) (Patch ID: OSF350-172)
********
This patch corrects a problem where printjobs cause existing jobs to be deleted
from the queue whenever the number of print queue entries exceeded 1000.
Example:
           The cfA005bozo file in /usr/spool/lpxx exists.
           The next print queue tries to create cfA005bozo.
           After error message "Cannot create cfA005bozo" shows up, do
           "ls -l /usr/spoo/lpxx/cfA005bozo".  This file will be
            deleted.


PROBLEM:  ( MGO101607 ) (Patch ID: OSF350-183)
********
This patch corrects a problem in which print jobs created within a short
timeframe, for example within the same second, were not sorted by print jobs
and timestamps.  This  resulted in print jobs not being printed in the desired
order.

Example: Prior to the fix

        #ls -tr *.lis
        users.lis users1.lis users2.ls users3.lis users4.lis
        users5.lis

        6th     0    bozo       8       users5.lis              23

As you can see, the file users2.lis has Job number 5 which is the 3rd Job
but gets ranked in the 5th position and will not be printed in the desired order
after the file user1.lis despite of the fact that all files had been created with the
same timestamp (eg. Jul 11 10:07).

Example: the order should be the following after the fix

        # lpq -Pxxx

This patch fixes a problem where the lpq command causes the program to crash 
(segmentation fault). 

The problem is caused by lpq running until a print queue buffer 
in memory is overwritten.

  corrupt or invalid saved sets, or file open failures.

- Fixes a problem in which the vrestore command fails when running 
  multiple iterations of the command in a script or from the command line.

- Fix incorrect vdump file count message that shows up when vdump backs up
  a filesystem containing sockets.

This patch corrects the following:

- Fixes a system crash when setting the date on SMP systems.

- Fixes a system panic with the following panic string:

    "event_timeout: panic request"

- Fixes a SCSI error recovery problem to allow fast recovery from disk errors.

- Fixes a problem that occurs when starting up a system
  that is running the auditing subsystem and the performance manager.
  The system panics with the error message:   kernel memory fault

- Provides general support for Version A11 KZPSA firmware.

- Fixes the problem of a system hang due to corruption of 
  a STREAM synchronization queue's forward pointer.  
  The system hangs in the csq_cleanup() function.

- Fixes a problem that causes systems to panic with a "kernel memory fault"
  from u_dev_lockop().  This has happened when a database tried to memory map
  a file.

- Fixes an I/O queue corruption problem that occurs during
   normal shut down of SMP systems with AdvFS.

- After a disk error occurs, mirror set switching may not happen soon enough
  to ensure high availability, or in some cases may not happen at all.

- Fixes a problem that may occur after a system panics.
  The system may hang when trying to do a crash dump.

- Fixes panics that may occur on SMP systems with message:

    "simple_lock: time limit exceeded"

- Fixes a problem that occurs when running STREAMS.  The system panics
  with a kernel memory fault in either osr_run() or osr_reopen().

- HSZ40s are not logging non-retryable errors in the errorlog.

- Provides the following additional event logging by the SCSI/CAM disk driver:

    Additional Unit Attention messages, additional details for hard errors
    logged after unsuccessful I/O recovery attempts, and provides informational
    messages on the progress of recovery events.

- When HSZ50 hardware is installed, the system exhibits very slow performance.

- Eliminates panics that will occur when attempting to execute
  shell scripts on a filesystem mounted with the "noexec" option.

- Fixes the corruption of core files produced by applications
  with 15 or more threads.

- Fixes two system panics - no special situation that will cause these panics;
  they can occur during normal system operations.
    o Fixes a panic that prints "pmap_dup: level3 PTE not valid".
    o Fixes a panic that prints "kernel memory fault".

- Fixes a problem with the exec() system function where a shell script 
  that has "#! <a setuid program>" as the first line of the script, 
  invokes the program but does not set the effective user id for 
  the execution of the program.

- Fixes a problem that occurs on AlphaServer 8200 and 8400 systems
  when a processor fails to restart after a user halts the system 
  by entering "Control-P Control-P" and then typing "continue" on the console.

- Fixes a number of problems relating to signals and POSIX 1003.1b timers in 
  multithreaded programs running on multiprocessor systems.  These problems 
  can result in missed timer-expiration signals and system crashes.

- Fixes a problem in which the the lastcomm accounting command doesn't print 
  the "S" flag at appropriate times.  This patch also improves the performance
  of lastcomm.

- Fixes system panic with "Zombie walks again" panic message.

- The system panics with "ipc_thread_init: reply port allocate" after an
  unsuccessful port allocation request.

- An aio application that calls aio_suspend() with a list of control blocks
  containing a duplicate address can crash the system if the duplicate aio
  request has not completed at the time of the call.

- A system with large shared memory segments and a large number of users may
  hang or panic when these users disconnect.  The solution here is to make use
  of unmanaged memory, granularity hints, and shared level 3 page tables.

- System Panics:
	o "thread_depress_wait" on multi-processor machines running
	  multi-threaded applications.

	o "simple lock owned" panic.

	o the following kernel memory fault panics:
		* generated from procfs_readdir()/uiomove().
		* fault_pc is in the u_anon_free() routine.
		* in ubc_sync_iodone().
		* when a user changes virtual memory (vm) tuning parameters due
		  to slow performance and reboots the machine.
		* generating a message such as: trap: invalid memory read
		  access from kernel mode
		* when system is running a number of processes which is > than
		  half the value of npid.
		* the fault came from malloc or spec_reclaim.
		* on systems running System V applications or any user process
		  compiled with the System V environment, even if System V is
		  not loaded on the system.

- Fix memory and process state output from /proc PIOCPSINFO ioctl and SVE ps
  command.

- Cannot kill a multithreaded process.

- Processes on a system may block in an uninterruptible state and never run
  again. This problem occurs when using NFS loopback mounts.

- User programs can end with a segmentation violation error when trying to
  allocate memory that grows in a downward direction.  This problem has been
  seen with Fortran programs that use automatic arrays, and with C programs
  that use the alloca() function.

- A process can hang and a "kill -9" command will not kill it. The ps command
  will show the status of the process as "U". This is a rare problem that is
  due to a file system timing problem which occurs during an internal sync and
  is difficult to reproduce.

- When executing with OSF PALcode revision 1.45, or greater, some floating point
  instructions fail.

- POSIX timer problems: corrupted signal queue (SMP panic) and hung sigwait.

- Various Alphaserver 8400 errorlog fixes; SMP platform fix to clear MCES
  register on secondary cpus.

- Corrects an SMP/realtime-preemption race condtion in the signal code that
  can allow a process stopped in sigsuspend to miss a signal wakeup and
  remaining block indefinitely.

- Alphastation 600 5/xxx has reporting/handling problems with single bit ECC
  Errors.

- Corrections for Handling Time:
	o Fix leap-year February time loss problem.

	o Allow clock to properly wrap at end of year when system is powered
	  down and to prevent clock loosing a day on each reboot during March
          of a leap year.

- Multi-processor systems using the AdvFS file system particularly systems also
  using AdvFS for the root and usr file systems may experience intermittent
  freezing of interactive processes when the system has a moderate to heavy I/O
  load.

- Corrects problems in tlb shootdown code:

        - Tlbshootdown requests could panic with timeouts because the
          other processor(s) do not respond to the interrupt.

        - The system may display invalid "tlb invalidate" messages.

        - There could be some memory data corruption or a memory fault.

        - Other processors in a cluster could have touched memory while
          it was being reset.

- In some adverse situtations the SWXCR controller may hang.

- Fixes some hangs that can occur during the "syncing disks..." portion of panic
  processing, improves the reliability of getting a dump after a system panic,
  and also makes it more likely that AdvFS buffers will be synced to disk after
  a system panic.

- Processes can become hung during a system call to table(). Debuggers are
  particularly prone to this problem.

- Corrects a problem where a remote user will kill rlogin or telnet and the
  server host will have an orphanned login process and rlogind or telnetd
  process in sleep state indefinitely.  This is seen only with Asian tty (atty)
  or any other host which is running c-list rather than STREAMS ttys.

- The Unix kernel crashes during installation if the memory in the system
  exceeds 1GB.  This has only been seen on Lynx-class systems with greater than
  1GB of memory.
PROBLEM:			(Patch ID: OSF350-055)	
********
A system with large shared memory segments and a large number of users may 
hang or panic when these users disconnect.  The solution here is to make use of 
unmanaged memory, granularity hints, and shared level 3 page tables. 

The following is a typical stack trace for this problem. This will be the stack
trace for one of the processes attempting to detatch from the shared memory.
A separate process may time out and panic the system attempting to acquire the
lock held by this process.

..............................................................................

General Information for editing kernel tuning/configuration parameters in 
 /etc/sysconfigtab:

This patch implements four separate changes that all contribute to greatly
reducing the shared memory detach time. It will also improve the page fault
handling time and the time needed to attach a shared memory segment after the
initial attach.

1. Granularity Hints for shared memory segments:
************************************************
The granularity hints fix makes use of the granularity hints bits in 
the page table entry (PTE) as specified in the Alpha Architecture references.
Granularity hints is a Translation Buffer (TB) optimization that allows
the TB to map more than a single page.  Enabling the granularity hints fix 
also enables the shared PTE fix.

The granularity hints fix is enabled by setting the "gh-chunks" parameter in
/etc/sysconfigtab.  The gh-chunks parameter is the number of 4 Megabyte chunks
reserved at boot time for shared memory use.  
  
edit /etc/sysconfigtab:

vm:
	gh-chunks=512

	    OR
vm:
	gh-chunks=0x200

Example: setting gh-chunks to 512 decimal will reserve 2 Gigabytes of physical memory
for shared memory segment use. Those pages will not be usable for any other purpose.

The calculation is:

	In decimal:  4194304 * 512 = 2147483648
	In Hex:	     0x400000 * 0x200 = 0x80000000
	
NOTE:  Memory that is set aside at boot time for shared memory by specifying 
a value for gh-chunks will not be used for anything other than shared memory.  
Unused memory from this region is not given back to the system.

There is a short sequence of dbx commands that can be used to determine
if there is extra memory (beyond that required by the application) being
allocated at boot time with gh-chunks.  The commands are:

	# dbx -k /vmunix /dev/mem
	
	(dbx) px &gh_free_counts
	0xfffffc0000681748
	(dbx) 0xfffffc0000681748/4X
	fffffc0000681748:  0000000000000402 0000000000000004
	fffffc0000681758:  0000000000000000 0000000000000002
	(dbx) q
	#

The first  number (402) is the hexadecimal number of free 512 page (4MB) chunks,
the second number   (4) is the hexadecimal number of free  64 page (512kb) chunks,
the third  number   (0) is the hexadecimal number of free   8 page (64kb) chunks and
the fourth number   (2) is the hexadecimal number of free   1 page (8kb) chunks.

This command should be run while the application, which allocates shared memory, 
is running.  The size of gh-chunks can be lowered such that there is only a 
few (1 or 2) 512 page chunks still free with the application running.

Other vm: /etc/sysconfigtab options you may wish to use:

vm:
        gh-min-seg-size=N

# requests (shmget) at or above N bytes will use memory from the gh-chunks 
#  region.  Default is 8388608 bytes.


# if the following flag is set to 1 and the request is larger than
# gh-min-seg-size but there is not enough memory in gh-chunks area
# to satify the request (shmget) then a failure is returned to shmget.
#
# If this flag is zero, then the entire request will be handled in
# the pageable memory area.  Default is 1.

vm:
	gh-fail-if-no-mem=1


2. Shared PTEs for shared memory segments:
******************************************
The shared PTEs fix enables sharing of Level 3 page table entries in the memory 
specified above by gh-chunks, resulting in a substantial savings of system 
memory.  

To be able to Level 3 PTEs, the shared memory segment attach address 
(in the shmat() system call) and the size of the shared memory segment 
(in shmget()) must be aligned on an 8 Megabyte boundry.  This means that 
the lowest 23 bits of the address and size  must be zero.

Note 1:  The attach address and the total size of the shared memory segment 
         is specified by the application.

Note 2:  System V shared memory semantics allow a maximum shared memory segment
         size of (2 GB - 1).  Specify a max value of (2Gb - 8mb) in DEC UNIX.
         Applications that need shared memory segments larger than 2 GB should
         construct such regions by using multiple segments.
                                                                
The above notes imply that the total shared memory size specified by the user
to the application must be 8 MB aligned.  In addition "shm-max", the size
specifying the maximum System V shared memory segment size must be 8 MB aligned.

If the total shared memory size specified to the application is greater than
2 GB, it is reasonable to set "shm-max" as follows:

vm:

ipc:
        shm-max=2139095040      ( this is = 2gb - 8mb )
                OR
        shm-max=0x7f800000


Note 3:  This is the maximum value of "shm-max" that will allow sharing of PTEs.
         The maximum value for "shm-max value is calculated using the formula:

  shm-max = 2GB - 8MB.

There is a dbx command that can be used to determine if PTEs are being shared.  

The command is:

	dbx -k /vmunix /dev/mem 

	(dbx) p *(vm_granhint_stats *)&gh_stats_store
	struct {
	    total_mappers = 21
	    shared_mappers = 21
	    unshared_mappers = 0
	    total_unmappers = 21
	    shared_unmappers = 21
	    unshared_unmappers = 0
	    unaligned_mappers = 0
	    access_violations = 0
	    unaligned_size_requests = 0
	    unaligned_attachers = 0
	    wired_bypass = 0
	    wired_returns = 0
	} 
	(dbx) q
	#

The fields of interest are:
	shared_mappers
	unshared_mappers
	unaligned_attachers
	unaligned_size_requests

For best performance you should see:

        shared_mappers = <the number of shared memory segments>
        unshared_mappers = 0
        unaligned_attachers = 0
        unaligned_size_requests = 0

Due to how shared memory gets broken up into shared memory segments, there
may be some unshared segments.  This is due to the starting address or the
size not being 8 Megabyte aligned.  This may be unavoidable in some cases.

Please Note:  In many cases the total_unmappers will be greater than the
number of total_mappers.  This is normal behavior.


3. Rework of shared memory locking for better parallelism:
**********************************************************
The shared memory locking rework changes a lock that was a single lock 
to a hashed array of locks.  The size of the hashed array of locks is 
tunable with  "vm-page-lock-count" in /etc/sysconfigtab:

vm:
	vm-page-lock-count=64


4. Improved Kernel Malloc Garbage Collection
********************************************
There are NO tunable parameters relating to the improved kernel malloc()
garbage collection.  This is enabled by default and cannot be disabled.


PROBLEM:	(QAR 40933)			(Patch ID: OSF350-103)
********
The system may panic if a process is bound to a processor 
(e.g., runon 1 ls -lR /) and the processor with the bound job is then halted 
(e.g., psradm -f 1). panic: thread_block: simple lock owned.

runon 1 ls -lR / > /dev/null &

running multi-threaded applications.


PROBLEM:	(MCPMB3AE6)			(Patch ID: OSF350-106)
********
This problem results in a kernel memory fault generating a message such as:

        trap: invalid memory read access from kernel mode

            faulting virtual address:     0xffffffff80914000
            pc of faulting instruction:   0xfffffc00004e6cbc
            ra contents at time of fault: 0xfffffc0000444aac
            sp contents at time of fault: 0xffffffffa95d70d0

        panic (cpu 0): kernel memory fault

where the pc is in uiomove(), and the faulting virtual address would be
the beginning of an unmapped page.  Because of the incorrect source
address calculation, uimove() will typically go well beyond the internal
buffer into unmapped territory.

PROBLEM:	(QAR 42141)		(Patch ID: OSF350-110)
********
An aio application that calls aio_suspend() with a list of control blocks
containing a duplicate address can crash the system if the duplicate 
aio request has not completed at the time of the call. 

The stack trace of the crashing thread will have at least the following frames:

PROBLEM:	(UVO103764)		(Patch ID: OSF350-113)
********
Fixes system panic with "Zombie walks again" panic message.

 
PROBLEM:        (QAR 42447)              (Patch ID: OSF350-125)
********
The /proc PIOCPSINFO ioctl returns incorrect data for the pr_state, pr_size, and
pr_rssize fields of struct prpsinfo.  The state field may show the process 
running (R) when it is in fact sleeping (S). The rss field will consistently 
show 0;  and the size field will usually significantly underreport the virtual 
address size of the process.

These symptoms may be observed directly through the use of the PSINFO ioctl, or 
indirectly through the use of the ps command from the System V Environment 
(SVE) layered product.

The problem can also cause the SVE gcore command to fail.


PROBLEM:	(QAR 43054) 		(Patch ID: OSF350-126)
********
When a multithreaded process is killed, stopped or otherwise is caused to stop 
or exit asynchronously, it hangs.  The process goes into an un-interruptible 
wait state, typically indicated by a "U" in a ps output.  Besides a reboot 
there is no other way to remove the process.

A typical stack trace on such a hung process will have a few threads in
the following state:

When a user changes virtual memory (vm) tuning parameters due to slow
performance and reboots the machine, the system panics.  This can occur when
setting vm tuning parameters to improve X Windows performance in systems under
heavy memory loads.  This problem is commonly referred to as "window freeze"
and was first discovered on Alphastation 500/600's. Note, the problem is not
exclusive to 500/600's.

VERIFICATION / VM TUNING PARAMETER ADJUSTMENTS:

The windowing system on AlphaStation 500/600's may experience
poor window response in a heavy paging environment.  Although this problem
occurs on all platforms, it is most pronounced on AlphaStation 500/600's.

Mouse movement on the system is uneffected, but windowing operations
such as exposing a window, dragging a window, and so on, are degraded.  When
this condition occurs, you may not be able to telnet or rlogin to the
system.  These symptoms can occur for some period of time (greater than 2
minutes), or may subside after a few seconds. The cause of these symptoms is
due to a memory intensive application(s) depleting the number of pages on the
free list to an absolute minimum.  When this occurs, only privileged tasks
are able to get memory (for example, free pages) and all others tasks are
blocked (in this case the window manager).

Check to see if your system is experiencing this problem by running "vmstat 2"
in a separate xterm while your application(s) are running. Your system will
display output similar to the following:
                                                                                #

Note the amount of free pages available under the column "free".  If this
number falls below the reserved amount (vm-page-free-reserved), your system
has hit this condition.

In the previous example, "vm-page-free-reserved" is set to its default value
of ten pages.  The previous example shows that the VM subsystem has been
overwhelmed.  If this is the case on your system, you will most likely
experience degraded window performance along with other performance
degradations. If the vmstat output on your system does not exhibit these
results (or similar ones), DO NOT tune your system per the recommendations
in this note.

GUIDELINES FOR CHANGING VM TUNING PARAMETERS:

1. Run "vmstat 2" to determine if vm tuning parameters should be changed.  (See
previous section, "PROBLEM VERIFICATION").

2. Update the vm-page-free-target, vm-page-free-optimal, and vm-page-free-min
tuning parameters in the /etc/sysconfigtab file.  If your system has less
than 128 MB of memory, try doubling from the default values until you reach
a happy medium between application performance and user interactivity. Note,
the default values are 128, 74, and 20, respectively.  Refer to the "System
Tuning and Performance Management Manual" for more information on system tuning.

The following parameter values provide fairly good interactivity with moderate
performance degradation on a Alphastation 6000 with 128M of physical memory:

vm:
 vm-page-free-target=4096
 vm-page-free-optimal=4096
 vm-page-free-min=2048

The numbers provided in the previous example are designed to keep a larger
than normal number of pages on the free list (as a buffer) by starting to page
earlier than normal (via a larger vm-page-free-min) and by stopping paging
later than usual (via a larger vm-page-free-target).  In addition, swapping
of tasks is enhanced to force the memory crunching task to be swapped out
occasionally (via a larger vm-page-free-optimal). You may find that your
system behaves fine with some manipulation of these parameters.  Note
that these tuning parameters were devised to provide some level of user
interactivity in a heavy paging/swapping environment.  They may not be the
best solution for your particular needs, but may provide a reasonable starting
place. Note, if your system does not have 128M of memory, pare down these
numbers. The units for these values are pages (which are 8KB) resulting in
some hefty chunks of memory (for example, 32MB).  Again, try doubling the
default values until you reach some happy medium. You can check the default
values using dbx as follows:

# dbx -k /vmunix

(dbx) p vm_page_free_target
2048
(dbx) p vm_page_free_optimal
1029
(dbx) p vm_page_free_min
20
(dbx) p vm_page_free_reserved
10

3. Reboot the system.

4. Raise the priority of the window manager (mwm or dtwn).
   a. Open a DECterm and kill the currently running manager.  For example:

      kill -9 pid

      Note that the pid is the process ID of the window manager found using
      the ps ax command.

   b. Restart the window manager using the system utility "nice".  For example:

      nice -2 mwm &

      or

      nice -2 dtwm &

If the system is tuned correctly, what you should see happen is a small
latency when the memory intensive application starts which will balance as
the memory subsystem recovers.  You should be able to expose
windows and drag them around, and so on.  If you expose a window that
has not been used for some time, expect some latency.  Remember, you are now
working in a heavy paging/swapping environment and those pages are not yet
available.

You will need to kill and restart the window manager each time you terminate
your X session.  Remember, you will need to be a privileged user (for example,
root).

After performing the previous steps, you should see marked improvement in user
interactivity when the system experiences heavy memory loads.

On SMP systems running applications that use POSIX realtime timers, the process
queue of delivered signals could become corrupted, causing the processor to loop
forever scanning the signal queue. Because this processor loops holding the 
process lock, a thread running on another CPU will eventually experience a 
lock-timeout panic attempting to aquire the process lock of the looping process.

The panic messages and stack traces of the affected processors will resemble 
the following crash data output:

A scan of an SMP/realtime system's processes with the ps command
locates a process that is stopped with a "pause" WCHAN with an
unblocked signal pending.  This process is blocked in the sigsuspend
syscall and has missed being awakened by the pending signal. The ps
output for this process might look like this:

# ps -O sig,sigmask,sigcatch,wchan -p 1500
  PID    PENDING    BLOCKED    CAUGHT    WCHAN
 1500          1          0         1    pause

This output shows that process 1500 is blocked in sigsuspend() trying
to catch signal 1 (SIGHUP). The signal is unblocked *and* pending.
This is an incorrect state when it persists indefinitely. Sending this
process a SIGHUP signal from a terminal will clear the blocked state
temporarily, but the problem is likely to recur

The Alphastation 600 5/xxx has reporting/handling problems with
single bit ECC Errors per the following symptoms:

- Processor detected single bit ECC errors are not logged correctly.
  This means that the necessary data needed to isolate this to a failing
  memory SIMM is not available to a customer.

- System detected single bit ECC errors are not handled due to the CPU switch
  not containing a handler for system detected single bit ECC errors.

  This results in either an installation failing or a system hang once a
  system detected ecc error occured.

Hardware affected:

Symptoms:

        the systems of these problems will be the following:

        - incorrect information logged on processor detected ECC errors
        - System hang on System Detected single bit Ecc errors

How to reproduce the problem:

        - Use an ALCOR system with a single bit ECC error present in it.
          Once you run across this error via the use of the bad memory
          you will either get an incorrect error log or system hang.

A typical stack trace is shown below:

       _Xsyscall

The problem is closely related to processes that use the "plock" system call 
in order to lock their text and/or data segments in memory. When such a process
attaches itself to a shared memory segment, the "shmat" system call allocates 
the required physical pages and "locks" them in memory.  There may be a 
resource shortage in this situation if (e.g.) there aren't enough free pages 
available.

This patch corrects problems in tlb shootdown code:

        - Tlbshootdown requests could panic with timeouts because the
          other processor(s) do not respond to the interrupt.

        - The system may display invalid "tlb invalidate" messages.

        - There could be some memory data corruption or a memory fault.

        - Other processors in a cluster could have touched memory while
          it was being reset.

There is no stack trace available.  If you see a panic with a tlb shootdown 
timeout panic, where it appears that one processor has posted a tlb shootdown,
but other processors have not responded, then this patch may fix the problem.

It is also possible to see memory data corruption or a memory fault.

The fix for clusters was made as a preemptive fix in conjunction with fixes for 
the other problems here.  There are no known instances of problems of this type.

This patch is MOST likely to fix the problem if the chip is an EV-5. It MAY fix 
the problem if the chip is an EV-45. For older slower chips, lack of this patch 
is probably not the problem.

This bug causes panic that results in the following console messages:

trap: invalid memory read access from kernel mode
    faulting virtual address:     0x0000000000436244
    pc of faulting instruction:   0xfffffc0000431148

    sp contents at time of fault: 0xffffffff9aee75b0
panic (cpu 1): kernel memory fault

The panic stack trace can originate from any number of sources, but will
pass through malloc(), which takes a memory fault leading to a panic:

>  0 stop_secondary_cpu() ["../../../../src/kernel/arch/alpha/cpu.c":352]
1 panic("event_timeout: panic request")

13 _XentInt() ["../../../../src/kernel/bsd/subr_prf.c":669]
14 idle_thread() ["../../../../src/kernel/kern/sched_prim.c":2811]

Note that the important part of the trace is from frames 0 through 8; the
caller of malloc() is not relevant, and is unrelated to the problem.

This specific bug can be verified by adding the KSEG base address of
0xfffffc0000000000 to the faulting virtual address taken from the
error message above, and determining what the resulting address represents:

(dbx) (0xfffffc0000000000 + 0x0000000000436244)/i
  [pgrp_ref:584, 0xfffffc0000436244]    bsr     r26, simple_unlock(line 273)
(dbx)

If the result is in pgrp_ref() like above, then this fix is the solution.

Another relevant symptom is that the kmembucket chain containing freed
process group structures is corrupted by the faulting virtual address;
This can be verified by noting that the "kb_next" field in kmembuckets[3]
contains the same faulting address:

(dbx) p kmembuckets[3]
struct {
    kb_lock = struct {
        sl_data = 0x431129
        sl_info = 0x0
        sl_cpuid = 0x0
        sl_lifms = 0x0
    }
    kb_next = 0x436244
    kb_size = 0x80
    kb_free = 0x444
    kb_total = 0x1240
    kb_elmpercl = 0x40
    kb_highwat = 0x800
}
       
There is no known manner of reproducing the problem; however, on systems where
it happens, it is a fairly regular occurance.

A dangling "s_ttyvp" vnode pointer in a session structure can allow a reference
to the session structure after it has been freed.  This corruption eventually
causes a panic in an unrelated malloc() from kmembuckets[2], from which
session structures are allocated.  The corruption to the freed session
structure can be identified by looking at the faulting address, which
indicates that the corruption was done in ttyclose():

This patch fixes a problem in which the system panics with a kernel memory fault
in k_mem_fault.  This is caused by a user application that calls one of the 
vectored IO system calls and passes an invalid kernel address as one of the 
arguments.  This invalid address is not properly validated by the kernel and 
therefore causes the kernel memory fault.

         The typical stack traceback is as follows:

         1.) panic(kernel memory fault)
         2.) trap()
         3.) _XentMM()

In some adverse situtations the SWXCR controller may hang.  There is a SWXCR
Driver timing issue where a rebuild in process can cause the controller to
delay I/O completion and timeout commands.  The driver will start to reset the
controller and eventually the controller will hang.  This is evident by the
fact that I/Os issued to that SWXCR controller do not complete.  This patch
will correct this problem.

                              
PROBLEM:  ( HPXQ43C4D, TKTR52185, QAR 46016 ) (Patch ID: OSF350-277)
********
This patch fixes some hangs that may occur after the message "syncing disks..." 
is printed when the system panics.  When these hangs occur, the completion of 
the "syncing disks..." message - the word "failed" or "done" does not get 
printed, and the system does not take a dump.

In addition to fixing these known hangs, a timout mechanism is added to the
"syncing disks" logic that will improve the reliability of getting a dump by
using the system clock to break out of the "syncing disks" path and take
a dump if no progress is being made on reducing the number of buffers to be
flushed.  The numbers printed periodically between the "syncing disks..."
and "done" messages are the number of buffers left to flush.

This patch also makes it more likely that AdvFS buffers will be flushed to
disk during the "syncing disks..." processing after a system panic.  There
is still no guarantee that writes in progress at the time of a panic will be
completed.

and kills the remote-access application (telnet or rlogin) during the login
procedure (at the "Password:" prompt) then the rlogind or telnetd process will
be left in a sleep state indefinitely.  This condition can be recognized by the
presense of rlogind or telnetd processes in the process table with no associated

********		(Patch ID: OSF350-295)
This patch fixes a problem in which the the lastcomm accounting command 
doesn't print the "S" flag at appropriate times.  This patch also improves 
the performance of lastcomm.

The problem was that the kernel did not properly update the accounting field 
that prints the "S" flag.  The "S" flag should be printed for each command 
that is run with an effective user id of 0.  Commands that are set-user-id 
to root, will print the "S" flag.  Also, commands that are executed by root, 
but are not set-user-id, will print the "S" flag.  Therefore, when "S" is 
printed from lastcomm for a certain command, it means that the user had
root privileges at some time during the execution of the command.

The algorithm used by lastcomm has been enhanced to improve its performance.

When debugging multithreaded applications with Ladebug, debugging sessions
may hang due to a bug in procfs (i.e., /proc filesystem).  

A simple way to reproduce the problem is to set a breakpoint in separate 
threads, run the application, change the thread focus to a thread other than 
the one which took the breakpoint, and to single-step.  Under these 
circumstances, the debugger does not return to the debugger prompt 
and the debugging session effectively hangs.  At this point, ps output 
simply indicates that the debugger and the debuggee are sleeping interruptibly.
However, when a SIGKILL is sent to the debuggee, the affected threads o
in the debugged process enter an uninterruptible sleep ('U' state in 
the ps listing).  The traced process is now unkillable.

This patch fixes a number of problems relating to signals and 
POSIX 1003.1b timers in multithreaded programs running on multiprocessor
systems.  These problems can result in missed timer-expiration signals 
and system crashes.  These issues involve synchronizing timer creation, 
timer deletion, and timer reset within multithreaded programs.

Two distinct crashes are typical of the problems.

Here's a sample of the first crash, a signal panic:

        panic (cpu 0): psig: catch not set

With the following stack trace:

        > 0 boot
          1 panic
          2 psig
          3 syscall
          4 _Xsyscall

A sample of the second crash is shown in the following example:

This patch provides additional event logging of Unit Attention messages
by the SCSI/CAM disk driver to the binary.errlog file.

It also provides additional details for hard errors logged after
unsuccessful I/O recovery attempts, and provides informational
messages on the progress of recovery events.

With this patch, Unit Attention messages are logged if they are received during:

  a) Attempts to bring a drive online
  b) Sense data requests for reads and writes
  c) Recovery from a failed Test Unit Ready command

This is a mandatory patch for SMP systems.

This patch fixes panics that may occur on SMP systems. 

The panics occur when one processor is exiting and the other processor
is trying to perform a pmap_tbsync.

The following error message is displayed on the systems:

        "simple_lock: time limit exceeded"

A sample stack trace for the cpu panicking with
"simple_lock: time limit exceeded" is as follows:

PROBLEM:        (QAR 51268)     (Patch ID: OSF350-427)
********
After a disk error occurs, mirror set switching may not happen soon enough
to ensure high availability, or in some cases may not happen at all.

The problem is that the timeout and retry mechanisms that go into action
after a disk failure prevent prompt notification of LSM that there was an error.

********
This patch adds a mechanism to the poll() system call to allow it
to be used as a timer by passing in a null argument for the number
of file descriptors.

Currently the poll() system call will return immediately when passed
a null argument for the number of file descriptors.

SUPERSEDES PATCH:	OSF350-047 (47.00),  OSF350-303 (341.00),
			OSF350-333 (369.00)

This patch corrects the following:

- Fixes a problem with the tar "tv" command in reporting ownership on a file
  that had no legitimate owner at the time it was archived.  Based on the
  position of the file in the archive, tar returned the owner of a previous
  file, or the values -973 for userid and -993 for groupid.

- Fixes pax's tar and cpio archive handling to allow filesizes greater than 4GB.

- When pax command was requested to append to an existing archive, using a file
  list taken from standard input, pax exited with success, although no append
  was done.

- Disallow pax "b" < 512 to avoid creating corrupt files.

- The tar(pax) command doesn't correctly handle sparse files, especially Oracle
  database files.  Pre-allocated space is not replaced on restore.
PROBLEM:	(QAR 37865)	(Patch ID: OSF350-047)
********
When the pax command is requested to append to an existing archive, 
using a file list taken from standard input, pax exited with success, 
although no append was done. 


PROBLEM:	(QAR 37865)	(Patch ID: OSF350-047)
********
The pax program enabled a user to create a pax archive with 
an illegal blocksize ('b' option), causing the records to be seen 
as corruption and the archive to be unrestoreable.

Note: The pax program 'b' option specifies an argument that is interpreted as
      number of bytes (as documented). The man page fails to document that the
      value can be followed by 'b' (512 byte blocks), 'k' (1024 bytes) or 
      'm' (1024x1024 bytes), and that the minimum is 512.


PROBLEM:	(MGO101962 QAR 43077)	(Patch ID: OSF350-303)
********
If a database file has been created with pre-allocated but unused disk space,
the copy operation of tar does not preserve this pre-allocated space and the
restore (tar xv) operation will therefore create a file that is of the size of
the actual used blocks.


PROBLEM:	(MANBBP075 HPXQC1120)	(Patch ID: OSF350-333)
********
The pax program (invoked as pax, tar or cpio) would incorrectly handle
files larger than 4GB in size.  The program would not complain on creation 
of an archive, however it had truncated the filesize when writing it to 
the archive file header. Thus on extract, it would appear to have found 
a corrupt archive.  In addition it will now warn when it truncates a file 
that is too large to be archived (8 GB).


PROBLEM:        (SQO100400)     (Patch ID: OSF350-400)
********
This patch fixes a problem with the tar "tv" command in reporting ownership
on a file that had no legitimate owner at the time it was archived.
Based on the position of the file in the archive, tar returned the owner
of a previous file, or the values -973 for userid and -993 for groupid.

- Fixes a problem that occurs on SMP systems using LSM in which
  the system panics with a "simple lock time limit exceeded" message.

- This patch is required for large LSM configurations containing more than 256

This patch fixes a problem in which an LSM configuration database becomes 
corrupted when it grows beyond 128 KB. The LSM daemon displays an error 
message similar to the following when it starts up:

bad magic number

Attempting to create 1019 LSM volumes also corrupts the LSM configuration 
database (since the size grows beyond 128KB).

Once the LSM configuration database is corrupted, it will have to be re-created.

********
This patch fixes a problem that occurs on SMP systems using LSM in which
the system panics with a "simple lock time limit exceeded" message.

The problem is that the running process goes to sleep waiting for an
LSM simple lock that never becomes available.

A sample stack trace is as follows:
>  0 stop_secondary_cpu(do_lwc = 0x0)
   1 panic(s = 0xfffffc00005a1568 = "event_timeout: panic request")
   2 event_timeout ()

   7 simple_lock_time_violation()
   8 voliodone()
   9 biodone()
  10 cdisk_complete()
  11 xpt_callback_thread()

SUPERSEDES PATCHES:	OSF350-150 (150.00),  OSF350-209 (209.00)

This patch corrects the following:

- Fixes a wide variety of system panics and other problems caused
  by random memory corruption.  Problem noticed at sites hosting
  a lot of streams activity.

- Successive reads wait for VTIME to expire regardless of VMIN setting.

- Fixes pause or stall conditions of up to 30 seconds when an application calls
  the ldtty_close function in a STREAMS based implementation. After the pause
  or stall, the application resumes normal behavior with no other apparent side
  affects.
PROBLEM:	(HPXQ968A7)	(Patch ID: OSF350-150)
********
Successive reads wait for VTIME to expire regardless of VMIN setting


PROBLEM:	(HPXQ514E3, QAR 46310)	(Patch ID: OSF350-209)
********
This patch fixes pause or stall conditions of up to 30 seconds when an
application calls the ldtty_close function in a STREAMS based implementation.
After the pause or stall, the application resumes normal behavior with no
other apparent side affects.

This problem typically shows when an application outputs to a streams based
device.  For example, an application "prints" data to a printer on a terminal
server using LAT protocol.  The application may expect an immediate return
but instead, experiences a pause or stall for up to 30 seconds.  Obtaining a
stack trace when the stall or pause condition is occuring will show
the following footprint:

	0 thread_block()
	1 mpsleep
	2 streams_mpsleep
	3 ldtty_close
	4 close_wrapper
	5 csq_protect
	.....
	.....

After the 30 seconds expires, the application returns to normal behavior with
no other side affects noticed.  The stall condition in this example happened
with files in the size range of 4097 - 4960 bytes being queued to a printer
on a terminal server.  The size of the files by coincidence, hit the 30 sec
sleep timer just at the right time in order to uncover the bug.
There are no error messages during the pause or stall.  You must examine
the stack in order to determine if this patch applies to your condition.


PROBLEM:  (HPAQ41AAX STLQ23067 UVO105389 HPAQ116QT HPAQ50RP5 HPAQ400K4
********        ZPOBA0391 ZPOB60233)    (Patch ID:OSF350-411)

This is a mandatory patch for all systems.

This patch fixes a wide variety of system panics and other problems
caused by random memory corruption.  The problem has typically shown up
at universities, or Internet service providers hosting a lot of streams
activity.

The following symptoms have appeared in a variety of places throughout
the kernel.  Corrupted memory buckets are usually the 256-byte size, although
they could be any other size.

o Lock timeouts
o Kernel memory faults
o Unaligned kernel accesses

A typical stack trace is shown in the following example:

   3 panic("pmap_activate lock timeout")
   4 pmap_activate() [/src/kernel/arch/alpha/pmap.c":2710]
   5 thread_run() [src/kernel/kern/sched_prim.c":2295]
   6 idle_thread() [src/kernel/kern/sched_prim.c":3105]

In the stack trace above, the lock timed out because the lock structure
(at 0xfffffc0067fefe00) appeared to be locked when it really was not.
This was due to corruption of the structure by user data that had overflowed
from an mblk structure preceding this memory block.

To identify whether you have this memory corruption problem you have to
look beyond the stack trace.  The stack traces will vary considerably,
even on the same system, so the only way to identify this problem is to
find the corrupted memory bucket and look at the contents.

This is a typical 512-byte corrupted memory bucket.  The first 17 bytes of
data have been overwritten by data that belongs to another thread.  The
17 bytes have overflowed from an mblk structure preceding this memory bucket,
and have corrupted this memory bucket, overwriting pointers or locks or
whatever the first 3 quadwords used to contain.

(kdbx) 0xfffffc0067fefe00/32X
fffffc0067fefe00:  6918a5e6f04e78d3 cf7814aca7a32d6f
fffffc0067fefe10:  0000000000000043 0000000000000000
fffffc0067fefe20:  0000000000000000 fffffffffffffff8
fffffc0067fefe30:  0000000000000000 0000000000000001
fffffc0067fefe40:  000000000044a5cc 000000000000001a
        ...

If you display the block of memory immediately preceding the corrupted memory,
you may see an mblk structure there, if it is still around by the time the
crash dump takes place.

Sometimes the data that has corrupted the memory bucket is readable ASCII,
but more often it is unreadable binary data.

The number of bytes of data can be anywhere from 1 byte to several quadwords
of data.

    bytes long.

 o  The "showmount -e host" command times out and issues the error:

        Can't do Exports rpc: RPC: Timed out

The 'showmount' command has a 25 second time out, plus the typical showmount 
request returns in less than a second.  This problem has so far only occurred 
when the NFS server is exporting a large number of file systems hosted by a 
3rd party product (where a large number was greater than 100 of the 3rd party 
product's entries).

Another way to cause this problem is if the 'showmount' command is aborted via 
Control-C before the NFS server can return the list of exported file systems.

Other systems, such as PCs requesting a list of exported file systems, could 
also cause this problem.

Identifying limitations of original date command
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The date command was not able to accurately set the date past the year
1999.  For example:

	Display current date:
	$ date
	Tue Jul 16 11:01:50 EDT 1996

	Attempt to set the date to 12:55 PM, January 1, 2000
	$ date 0101125500
	Thu Feb  7 19:24:02 EST 2036

Enhancements to the date command for Year 2000 support
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The date command has been enhanced to support setting the system date
past the year 1999, providing customers with the ability to begin
testing their software for potential century rollover problems.  The
changes are outlined in the following sections.

Syntax

	The following formats are valid for setting the system date
	using the date command.

	Using the XPG4-UNIX format:

	date mmddHHMM[yy]

	Using one of three Digital formats:

	date mmddHHMM[[cc]yy][.ss]
	date [[cc]yy]mmddHHMM[.ss]
	date mmddHHMM[.ss[[cc]yy]]

	The following definitions apply:

	mm   is the month number
	dd   is the number of the day in the month
	HH   is the hour in the day
	MM   is the number of minutes
	ss   is the number of seconds
	yy   is the last two digits of the year
	cc   is the first two digits of the year

	Note that the LC_TIME variable, if it is defined, controls the
	ordering of the day (dd) and month (mm) numbers in these
	formats.  The default order is the month (mm) followed by the
	day (dd).

Optional Century [cc] Input

	Each of the Digital formats for the date command allow the
	optional input of the century (first two digits of the year).
	This century field is optional to ensure that input formats
	previously accepted by the date command are still supported.

	Currently, the XPG4-UNIX format mmddHHMM[yy] does not have a
	century field.  This is consistent with current X/Open
	specifications regarding the date command.  The century field
	will be added to this format in a future release of Digital
	UNIX once this new field is officially supported in future
	revisions of X/Open's UNIX specification.

Handling of Two-Digit Year Input

	When the year is specified by using two digits (as in the
	XPG4-UNIX format or when the [cc] field is omitted from the
	Digital formats), the century is determined in the following
	manner: if the specified two-digit year is between 69 and 99
	inclusive, the 20th century is assumed (that is, 19yy),
	otherwise the 21st century is assumed (that is, 20yy).

	The algorithm above is consistent with current drafts of
	forthcoming X/Open UNIX specifications regarding two-digit
	year handling in various system interfaces and commands,
	including the date command.  This algorithm is based on the
	standard UNIX epoch (12:00:00 AM Jan 1, 1970 UTC), minus one
	year to account for different time zones.  Internal UNIX time
	handling is based on the number of seconds since this epoch.

Handling of Ambiguous Input

	If the input string is ambiguous, that is, if the format
	cannot be conclusively determined from the data, the date
	command will issue a warning to STDERR and assume the
	mmddHHMM[[cc]yy][.ss] format.  To avoid ambiguous input, use
	one of the three Digital formats and specify the [cc] field.

Examples

	To set the date to 09:34:00 AM Jan 7, 2000:

	Using the mmddHHMM[yy] XPG4-UNIX format:

	# date 0107093400

	Using the mmddHHMM[[cc]yy][.ss] Digital format:

	# date 010709342000
	# date 0107093400.00
	# date 010709342000.00

	Using the [[cc]yy]mmddHHMM[.ss] Digital format:

	# date 0001070934
	# date 200001070934
	# date 200001070934.00

	Using the mmddHHMM[.ss[[cc]yy]] Digital format:

	# date 01070934.0000
	# date 01070934.002000

	An example of ambiguous input:

	# date 0101010000

	This input could be recognized as one of the following
	formats:

	mmddHHMM[[cc]yy][.ss]   meaning 01:00:00 AM Jan 1, 2000
	[[cc]yy]mmddHHMM[.ss]   meaning 12:00:00 AM Jan 1, 2001

	In this case, the date command will display a warning and
	assume the mmddHHMM[[cc]yy][.ss] format, setting the date to
	01:00:00 AM Jan 1, 2000.

ld generated an assertion in get_ext_map().

This problem appears to be the result of other problems occuring in the linker 
prior to the compact relocation code.  The linker is generating a relocatable 
image (preserving and updating relocation records), yet it has not set 
"relocatable=1" internally.  Thus, we attempt to generate compact relocation 
and also preserve regular relocations.  This causes the problem in the compact 
code.

The solution was not to adjust relocation record that are relative to undefined
symbols unless we are creating a relocatable image. The compactcode expect
unadjusted relocation records

********
ld causes an initialization order problem for DEC C++ programs linked 
-non_shared.  Unlike with -call_shared programs, ld calls __init... routines in 
the order that they are found on the ld command line.

DEC C++ constructs static objects by generating __init routines.  The generated
__init routines in the user's code can legally reference static objects [which
have __init routines] in the C++ class library (libcxx.a).  Unfortunately,
since user's .o files appear on the command line before libcxx.a, the user's
__init routines are invoked before the class library __init routines.  Thus
the user's __init routine will reference the class library before the latter ha
been initialized.

To get around this problem, DEC C++ declares a static object in each class
library header file.  The static object's constructor calls a routine that
initializes the class library.  Unfortunately, doing this requires that a call
to the initialization routine be made by every module that includes the header
file.  For large programs, this can result in thousands of unnecessary calls an
significant performance degradation at image startup.


PROBLEM:        (Patch ID: OSF350-086)           (QAR 32610)
********
(ld) shared library -init option problem.

Core dump occurred for external init routine when linking with -no_excpt.

Since the symbols being called are not defined in the executable, ld satisfies 
the references in the init driver using stubs.  A stub is a small code sequence 
that loads a symbol index and calls the loader to resolve it.  The stub *is* 
local to the executable, which means that the pc-relative jump can be made 
without a problem.

The init and fini drivers are invoked with the loader's GP as its initial GP 
value.  As inits and finis are called, they load their own GP value.  Stubs, 
on the other hand, need to have a valid GP value from which to load a GOT(0) 
value, this is the address of the loader's lazy_text_resolve() routine.  
Any valid GP will do, except for the loader's.  After the first init routine 
has been called, the GP value will be valid.

In this problem test case, the first init called is a stub'ed routine. Normally,
the exception handling init routines are first, but the -no_excpt linker 
switch causes them not to be linked in.

This problem has been fixed by establishing an initial GP value for the init 
and fini driver routines.

A shared library built with -check_registry so_locations may dump core accessing
.rdata symbols.  If the shared library grows too big for it's text to fit in 
the slot allocated for it in an so_locations file, ld will move the text of the 
library to the next available text slot. It then corrects all the text symbol 
addresses by adding the difference of the reserved text slot and the newly 
allocated text slot.  The difference is also added to .rdata symbols, but 
.rdata symbols are in data not text, so the resulting addresses are invalid.

incurred by ld.  The -nommap switch may be used on the cc command line, an ld

A call-shared application which overloads a shared library procedure with an 
additional implementation of the procedure in the main executable can 
"Segmentation fault". The problem may be sensitive to link order. Linking 
non-shared should cause the problem to go away. One may be able to determine 
that the gp register is incorrectly set.

This problem results from the linker incorrectly determining that the gp 
prologue can be "optimized away". You can not work around this problem by 
linking debug.

The patched linker correctly determines when this optimization can be applied. 
If an application does have this problem, you must install this patch and 
re-link to correct the problem.

Hidden/Export Symbol wildcard problem:

A regression was introduced into the linker when -hidden symbol

An example of wildcard usage that was no longer functional is:

  ld -o libf.so -shared -all -hidden  -exported_symbol 'X500*'  file.o -lc

Any symbol beginning with X500 should be "GLOBAL" not "LOCAL".
To check if a symbol is global use the following odump command

SUPERSEDES PATCH:	OSF350-049 (49.00),  OSF350-262 (262.00)

This patch corrects the following:

- Fix enables ar to find object modules specified for deletion or extraction
  whose names are longer than 13 characters.

- Failures may occur when nm or odump are run on certain compressed archive
  libraries built with the ar command.

- The ar command -x option, which extracts archive files, may, in error,
  return a message stating that the file was not found.
PROBLEM:	(QARs 33128,36370,36883,37335)	(Patch ID: OSF350-049)
********
When nm or odump are run on certain compressed archive libraries 
built with the ar command, the following failures *may* occur:
  (note - this does not happen with all archive libraries)

$ nm libm.a > /dev/null
Warning: Symbol table header magic is 0x4eff

Fatal: ran out of heap space
$ odump -tv libm.a > /dev/null
Warning: Symbol table header magic is 0x0

libmld: init_ldfile:non-mips symbol table 0

ifdMax), file ../../../../../../src/usr/ccs/lib/libmld/ldfcn.c, line 333
Resources lost(coredump)
$

Alternative if this patch is not installed:

- Do not use the objZ utility to pre-compress objects before archiving
  with ar, instead use "ar rZ".  
- Do not combine objects and non-object files (such as text files) in 
  an archive.  

In the absense of this patch, each of these cases has the potential of 
creating a bad archive symbol table, leading to the above problems.


PROBLEM:	(DJOB3K133, QAR 46595)	(Patch ID: OSF350-262)
********
The ar command's -x option, which extracts archive files, may,
in error, return a message stating that the file was not found.

To duplicate the problem, create a library with the command
  'ar r /tmp/foo.a /tmp/bar.o'.

Issuing the command 'ar -x /tmp/foo.a /tmp/bar.o' will generate
the message
  "ar: Error: /tmp/bar.o not found"
even though the file exists in the archive.

With the fix, the same command extracts /tmp/bar.o from /tmp/foo.a
without generating an error message.

This patch corrects the following:

- Fixes a problem where printing of a string with a specified precision
  could result in a segmentation fault.

- Fixes a TCP/IP problem that can occur with programs linked with
  the libc library. These programs may return a value of (-1)
  when calling the svc_tcp() function.

- /sbin/shutdown takes too long if there are many open LAT lines.

- Occasionally, users will still be present in /var/adm/utmp even after they
  have logged out.

- BIND clients cannot perform lookups when given a nameserver address that is an
  interface alias address on the BIND server. The lookup hangs for a period of
  time, then times out.
 
- A potential security vulnerability has been discovered, where under certain
  circumstances, system integrity may be compromised. This may be in the form
  of improper file or privilege management. Digital has corrected this
  potential vulnerability.

- On systems with worldwide support and message catalogs installed: when a
  locale is set, xdm (the workstation login screen) and the passwd command will
  core dump when displaying some messages.

- sprintf() can add one extra uninitialized character after "%*.*f" format
  strings if the precision is zero.

- A dataless system will hang when transitioning from single to multi-user mode.

- Multithreaded applications run on V3.2C which use any of the get*_r()
  functions may dump core or produce incorrect results.

- strncat() reads past end of source array.

- Fix multiple processes from adding duplicate ut_id lines in the utmp file with
  duplicate ut-id keys.

- Corrects several errors in the syslog entry written by the su program.

- taso applications that set the malloc(3) __sbrk_override and __taso_mode
  tuning parameters to true.  Under these circumstances, malloc(3) can return
  ENOMEM before all of the taso address space is allocated.

- A memory leak problem associated with the strxfrm() and wcsxfrm() functions
  and some incorrect behavior in __do_replacement(), which is used by both
  strxfrm() and strcoll().

- The filename pattern-matching behavior of the find command when it includes
  the "?" metacharacter. The bug actually resides in fnmatch(), which is used
  by the find command.

- In some cases, sendmail generates a core dump when it receives an illegal
  command, after installing patch OSF350-128.

- After a user logs into a system with an SRV4-style LAT device: When the
  ttyslot function is called, the system fails to find the device and returns
  a value of zero, indicating an error in the ttyslot function.

- A heavy load on a NIS server causing more than 32 connections, ypserv would
  "lose" some of them. Problem is more obvious on ypserv but can occur
  on ypbind.

- NIS slaveservers will not accept a push from the master server of a new map.

- A potential security vulnerability has been discovered in BIND
  (Domain Name Service), where under certain circumstances, system integrity 
  may be compromised.  This may be in the form of improper file or

PROBLEM:	(CLD MGO102122, QAR 45686) (Patch ID: OSF350-217)
********
This patch fixes a memory leak problem that occurs when strxfrm() or wcsxfrm() 
executes in a locale that allows one character to substitute for another during 
collation. An example is the de_DE.ISO8859-1 locale, in which "ss" is equivalent
to and may be substituted for the German sharp s. In such a locale, each 
invocation of strxfrm() or wcsfrm() causes some amount of heap memory to be 
leaked. When you apply this patch, the memory leak no longer occurs.


PROBLEM:	(QAR 38929)	(Patch ID: OSF350-217)
********
This patch also fixes some incorrect behavior in the __do_replacement() 
function, which is used by both strxfrm() and strcoll(). Before the fix, 
__do_replacement() might use the same string pointer for the source and 
destination strings in the strcpy() function. Results were unpredictable. In 
addition, __do_replacement() did not test the output buffer size to determine 
if the resulting string would indeed fit in the output buffer. The patch solves 
all these problems.


PROBLEM:	(QAR 45694)	(Patch ID: OSF350-222)
********
This patch fixes a problem in the fnmatch() routine's single-byte and multibyte 
versions, which incorrectly match '?' to a null character.  As a result, a 
filename pattern like "???" could match not only a filename containing "aaa", 
but also one containing "a" or "aa".  Because the find command uses fnmatch() 
for filename pattern matching, there is a chance that data files may be removed 
unintentionally.  An example is as follows:

        % find . -name 'data???' -exec rm {} \;

        This command could inadvertently remove files named "data1",
        "data10",  and so forth.

        Note that the problem fixed by this patch occurs only when you
        use locales other than the default C locale.

After patch OSF350-128 was installed, sendmail would generate a core dump with a

(1) On the system being tested, telnet to port 25.  
(2) Enter illegal commands and check whether sendmail generates a core dump.


PROBLEM:	(QAR 46198)	(Patch ID: OSF350-253)
********
The setlocale() function may sometimes pass a null pointer to the free() 
function. This is not harmful if site applications use the memory allocation 
package (malloc() and free() functions) bundled in the Digital UNIX C Library. 
However, if site applications use a locally developed memory allocation package 
or one included as part of a layered product, passing a null pointer to free() 
may cause the applications to fail. To avoid this problem, this patch installs a 
version of setlocale() that checks a pointer for null before passing the pointer
to free().


PROBLEM:	(BRO100738)	(Patch ID: OSF350-279)
********
When testing applications on a BSD-style device such as /dev/tty0h, the ttyslot 
function returns a number matching the index into the /var/adm/utmp file.  
However, when running the same program on an SVR4-style device such as 
/dev/lat/622, the ttyslot function always returns zero.  The problem can be 
indentified easily by running the sample test program included here.

Copy the following program to ttyslot_test.c:

#include <sys/ioctl.h>
#include <stdio.h>
#include <string.h>
#include <utmp.h>

main()
{
        printf("ttyslot() = %d\n", ttyslot());
        exit(1);
}

Error messages may vary, depending on which applications are being run. When 
connected to a system over an SVR4-style LAT device the application calls the 
ttyslot function to locate the entry in the /var/adm/utmp file. The ttyslot 
function returns zero in error because it fails to match the control terminal.  
When you connect to a system over a LAT device and make a ttyslot function call 
to locate the entry in the /var/adm/utmp file for the control terminal of the 
current process, ttyslot() returns zero in error because it fails to match the 
control terminal.

This problem is more obvious with ypserv, but it can occur on ypbind also. 
If there was a heavy load on a NIS server causing more than 32 connections, 
ypserv would "lose" some of them.  A "netstat -an" on the system would show 
many TCP connections in the "CLOSE_WAIT" state and ypserv would keep taking 
up more and more of physical memory.

Currently, the yppush process will print

twice, after a delay of several minutes, and then  
pushed <map>

but the map in fact does not get transferred to the slave.
With the patched ypserv running on the slave, the "transfer ..." messages 
do not appear, and the map is in fact transferred.

This patch corrects the following:

- Fixes a system panic when shutting down to single user mode using either
  one of the following commands when AdvFS is the root or usr filesystem:
     # shutdown now
     # init s

- Fixes system panic with the following error message:

   panic (cpu 0): kernel memory fault

- Fixes a problem with an NFS V3 mounted AdvFS file system
  where under heavy I/O load, data written to a file may be lost.
  Additionally, because file stats are not being saved, the file
  modification time may revert to a previous value.

- Fixes system panic with the following error message:

        AdvFS exception Module=26 line=1483

- Fixes AdvFS to prevent the following two panics:
  o AdvFS Exception  Module = 1, line = 1891
  o kernel memory fault

- Under heavy I/O loads, systems running with ADVFS and LSM may have sluggish
  interactive performance, or in DECsafe (ASE) environments, unexpected
  relocations of services can occur (using AdvFS filesystems).

- AdvFS will no longer check quotas when user is root.

- Any access of an AdvFS file could result in the system error messages "write
  failed, user (group) limit reached" or "quota exceeded too long", even though
  the file had have not been written to.

- The vquotaoff command may not report an error if it fails to turn off AdvFS
  quotas for a fileset.

- Quotas for AdvFS filesets are not turned off when the filesets are unmounted.

- System panics (with AdvFS in use):
	o The system panics with one of the panic messages:
		* "dealloc_bits_page: can not clear a bit twice!"
		* "AdvFS Exception Module = 41, Line = 549".
		* "ADVFS EXCEPTION Module = 1, Line = 487, N1 = 0".
		*  ADVFS EXCEPTION Module = 4, Line = 3541 "bs_unpinpg called
		   with buffer not pinned".
		* "clear_buf: bufCnt = 0" is too strict and has been removed.
		* "kernel memory fault" or "ADVFS EXCEPTION panic string:
		   N1= -1027" panics during backup operations using AdvFS.
		* "simple_lock: time limit exceeded".
		* Kernel Memory Fault panics:
			- when mounting a crashed AdvFS file system.
			- Advfs background thread doing I/O to inactive domain.
			- in ubc_page_alloc().

	o When either:
		* ls command is run in the fileset mount directory (containing
		  the .tags file)

		* msfsck is run at least twice and then the AdvFS fileset is
		  unmounted

- Newly created root filesets may not be assigned the correct unique id while
  booting the system. Utilities like vdump, find, DECnsr, etc may be unable to
  distinguish /proc as a mount point due to this problem.

- When AdvFS is the root file system, the system date is incorrect following
  reboot, even if "date" has been run and the correct date and time entered
  prior to the reboot.

- After rebooting the system, a file that was changed via mmap() without an
  msync(), may have corrupted data.

- Large reads can cause Advfs to perform poorly or hang.

- The getrusage system call returns zero for the values of ru_inblock and
  ru_outblock on an AdvFS file system.

- Fix NFS rpc.lockd "can not clear lock after crash of client" when AdvFS is
  being used.

- A system using AdvFS can run out of metadata space when the AdvFS domain
  still has some free space available. The system will display error messages
  such as "no space left on device".

- An AdvFS system returns an error message when attempting to create greater
  than 764490 files in a directory.

- System panics with "kernel memory fault" in ubc_page_alloc().

- Idle time is reset on broadcast message when AdvFS is the root file system.

- This patch fixes a problem that occurs with the telnet and ftp commands.
  Telnet or ftp processes that are no longer in use, are left on the system
  indefinitely.  When a user tries to log in, the login process hangs after
  displaying the last login message.
PROBLEM:	(TKTR71564,QAR 36411)		(Patch ID: OSF350-037)
********
Under heavy I/O loads, systems running with ADVFS and LSM can have

AdvFS will no longer check quotas when user is root.


PROBLEM:        (HPXQ64F10)			(Patch ID: OSF350-038)
********
Corrects the problem where any access of an AdvFS file could result in the 
system error messages "write failed, user (group) limit reached" or "quota 
exceeded too long", even though the file hadn't been written to.

A previous earlier write to the file had extended the file to the quota limit
and AdvFS improperly disallowed the creation of file fragments.  After a
subsequent reboot (clears an internal flag), any access to that file, even a 
read-only one, would initiate an attempt to create fragments on file close.  If 
the quota limit hadn't changed, the attempt to create fragments would fail and 
result in the above system error messages.


PROBLEM:        (QAR 37683)			(Patch ID: OSF350-058)
********
The vquotaoff command may not report an error if it fails to turn off AdvFS 
quotas for a fileset.  Specifically, if quotas are turned on but then the 
/etc/fstab entry for the fileset is modified to remove the 
"userquota,groupquota" clause and vquotaoff is run to turn off the quotas,
the quotas will not be turned off and vquotaoff will not report an error.


PROBLEM:        (QAR 36330,37137)		(Patch ID: OSF350-058)
********
Quotas for AdvFS filesets are not turned off when the filesets are unmounted.
More specifically, if quotas are turned on for an AdvFS fileset and then
the fileset is unmounted, the next time the fileset is mounted, quotas
will automatically be turned on; running the vquotaon command is not necessary.
This behavior differs from UFS and is considered to be incorrect.  The desired
behavior is to have the unmount turn off quota enforcement so that the next
time the fileset is mounted, vquotaon must be run to activate quotas.
This patch (QAR 36330) causes AdvFS to have this UFS-like behavior.
QAR 37137 is related to the same problem and is fixed in this patch.


PROBLEM:	(UVO103161)			(Patch ID: OSF350-094)
********
The system panics with "dealloc_bits_page: can't clear a bit twice!"

If this problem is seen, it is necessary to fix the filesystem by backing up the
filesystem, rebuilding the domain, and restoring it from the backups.  Then,
apply the patch, rebuild the kernel, and reboot.

This patch fixes two scenarios which can cause this panic.

but the ref count should not have been zero.

is doing a directory search of an AdvFS fileset, for example, this has
been seen during backup operations.  A typical stack trace is:

********
This patch fixes a problem in which the getrusage system call returns zero for 
the values of ru_inblock and ru_outblock on an AdvFS file system.

To observe the problem on a system where /usr is an AdvFS file system, do the 
following as root:

csh
cp /vmunix /usr/vmunix.tmp1
time cp /usr/vmunix.tmp1 /usr/vmunix.tmp2
# the time command shows 0+0io (before applying the patch)
rm /usr/vmunix.tmp1 /usr/vmunix.tmp2

This fix corrects a problem when remote NFS clients crash and reboot while
holding locks againsts files on an AdvFS files system.  Prior to this fix
the daemon.log file would receive messages similar to the following:

    can't clear locks after crash of client <ClientName>:  Invalid argument


PROBLEM:  (9WAB62151,QAR 46315,QAR 34257,QAR 35785)	(Patch ID: OSF350-272)
********
This patch fixes a problem in which a system using AdvFS can run out of
metadata space when the AdvFS domain still has some free space available.
The system will display error messages such as 'no space left on device'.

The problem may occur on a heavily fragmented system with many small files,
such as an Internet News server or Mail server.

To handle this problem, please use the -p and -x options when using
the mkfdmn command to create an AdvFS domain that is expected to have
many small files. Specifying the new -p option to the mkfdmn command
pre-allocates internal AdvFS structures and the erroneous 'out of space'
messages will not occur.

NOTE:  Please run the mkfdmn command with no options or arguments to list
       the updated mkfdmn man page and the -p and -x option descriptions.


PROBLEM:	(Q38248)	(Patch ID: OSF350-232)

This patch fixes a problem in which an AdvFS system returns an error message

mkdir: cannot create foo.
foo: No space left on device

PROBLEM:	(MANBCP087,QAR 50227)	(Patch ID: OSF350-356)
********
This patch fixes a problem that occurs on AdvFS systems in which the
system panics with the following error message:

        AdvFS exception Module=26 line=1483

This problem follows an I/O error, and may also cause memory and/or 
data corruption without causing a system panic.

The stacktrace of the panic thread will be as follows:

panic()
advfs_sad()
ftx_fail_2()
ftx_fail()
fs_write()
msfs_write()
vn_write()
rwuio()
write()
syscall()
_Xsyscall()

The problem may have also led to memory and/or data corruption,
without the above panic.

********
Fixes a system panic when shutting down to single user mode using either
one of the following commands when AdvFS is the root or usr filesystem:
    # shutdown now
    # init s

The cause of this problem is subject to the timing of several kernel threads,
therefore the symptoms or panic may occur intermittently and on different
platforms.
