Defect Description:
PHNE_32825:
1) CR JAGad76007 / SR 8606206834 :
Description:
The "tsize", "blksize", and "timeout" negotiation options
do not work in the tftp client and server.
Resolution:
The "tsize", "blksize", and "timeout" options now work
properly in the tftp client and server.
2) CR JAGae09213 / SR 8606241958 :
Description:
When the "tsize" option is set in a system with large
available disk space, tfptd(1M) fails with "Option
negotiation error" during a "put" operation.
Resolution:
tftpd(1M) now works properly for the "put" operation,
with "tsize" option set,in a system with large available
disk space.
3) CR JAGae76149 / SR 8606313351 :
Description:
tftpd(1M) does not respond under certain circumstances.
Resolution:
tftpd(1M) now responds properly.
4) CR JAGae89237 / SR 8606326973 :
Description:
Child tftpd(1M) process exits with SIGBUS error under
certain circumstances.
Resolution:
tftpd(1M) code has been modified to fix the problem and to
send a negative acknowledgement to the client.
PHNE_32449:
1) CR JAGaf47657 / SR 8606387504 :
Description:
DHCP/TFTP patch PHNE_28762 should supersede PHNE_29081 but
does not.
Resolution:
PHNE_32449 supersedes both PHNE_28762 and PHNE_29081.
PHNE_28762:
1) CR JAGad39835 / SR 8606170571 :
Description:
The static buffer size of the dhcpclient is 15 KB and it
can accommodate interface details of only 36 LAN
interfaces. Therefore, the interface list is truncated
when the number of LAN interfaces exceeds 36. The
dhcpclient exits when it does not find a specified LAN
interface in the interface list.
Resolution:
The dynamically allocated buffer is now used to store the
interface details when the static buffer size of 15 KB is
not sufficient.
2) CR JAGad52870 / SR 8606183657 :
Description:
When a DHCP client sends a duplicate request for lease,
bootpd tries to insert the duplicate entry in the internal
hash table. When bootpd fails to insert the duplicate
entry, it wrongly tries to free the static structure
instead of the dynamically allocated structure,
and dumps core with signal 11.
Resolution:
bootpd now frees the dynamically allocated structure
instead of the static structure.
3) CR JAGad97772 / SR 8606228718 :
Description:
During a dynamic DNS update, bootpd uses an incorrect
pointer and dumps core with signal 11.
Resolution:
bootpd now handles dynamic DNS updates properly.
4) CR JAGae16142 / SR 8606249756 :
Description:
bootpd attempts to store the hardware address mask in an
improper variable type which results in overflow of the
hardware address mask and improper functioning of bootpd.
Resolution:
bootpd now parses and stores the hardware address mask
properly.
5) CR JAGae30333 / SR 8606266080 :
Description:
bootpd dumps core with signal 11 under certain
circumstances.
Resolution:
bootpd code has been modified to fix the problem.
6) CR JAGae49090 / SR 8606285149 :
Description:
bootpd limits the T176 option in the /etc/dhcptab file to
61 characters of data.
Resolution:
The T176 option can now contain 255 characters of data.
7) CR JAGae49874 / SR 8606285933 :
Description:
bootpd dynamically allocates memory for certain fields in
the host information structure. But, the memory is not
freed after the host information is processed.
Resolution:
bootpd now frees the dynamically allocated memory for
individual fields, after processing the host information.
8) CR JAGae50734 / SR 8606286795 :
Description:
bootpd releases declined leases under certain
circumstances.
Resolution:
Code has been modified to rectify the problem.
9) CR JAGae71679 / SR 8606308645 :
Description:
During DHCPOFFER, bootpd dynamically allocates memory for
the hostname but does not free the memory after processing
the hostname.
Resolution:
bootpd now frees the dynamically allocated memory for the
hostname.
10) CR JAGae73843 / SR 8606310985 :
Description:
When a PXE client receives a class identifier option from
the DHCP server, the PXE client tries to boot up using the
Proxy DHCP server. In absence of an appropriate Proxy
DHCP server, the PXE client fails to boot up.
Resolution:
A configuration option 'ncid' is now available in the
/etc/dhcptab file that instructs bootpd to drop the
class identifier option in the reply message. This
helps PXE clients to boot up using the normal DHCP
server instead of the Proxy DHCP server.
11) CR JAGaf07529 / SR 8606346705:
Defect Description:
The bootp server does not properly initialize the lease
time with the configured lease value before sending the
OFFER packet to the client.
Resolution:
The bootp server code has been modified to properly
initialize the lease time with the configured lease
value before sending the OFFER packet to the client.
12) CR JAGad25107 / SR 8606155794 :
Description:
When a request is sent to an alias IP address in a
Service-Guard environment, tftpd replies with the primary
IP address in the source IP address field. Certain tftp
clients reject such a reply.
Resolution:
A new option "-s" has been added to enable tftpd to
function properly in service guard environment. However,
inetd.sec feature may not work properly when Service-Guard
fix is enabled using "-s" option.
13) CR JAGae80695 / SR 8606318163 :
Description:
tftpd exits under certain circumstances.
Resolution:
tftpd now functions properly.
PHNE_29081:
1) JAGae60488 / SR 8606296939
Description:
Under certain circumstances, tftpd can cause performance
problems.
Resolution:
The tftpd performance problem has now been rectified.
Enhancement:
No

Installation Instructions:
Please review all instructions and the Hewlett-Packard
SupportLine User Guide or your Hewlett-Packard support terms
and conditions for precautions, scope of license,
restrictions, and, limitation of liability and warranties,
before installing this patch.
------------------------------------------------------------
1. Back up your system before installing a patch.
2. Login as root.
3. Copy the patch to the /tmp directory.
4. Move to the /tmp directory and unshar the patch:
cd /tmp
sh PHNE_32825
5. Run swinstall to install the patch:
swinstall -x autoreboot=true -x patch_match_target=true \
-s /tmp/PHNE_32825.depot
By default swinstall will archive the original software in
/var/adm/sw/save/PHNE_32825. If you do not wish to retain a
copy of the original software, include the patch_save_files
option in the swinstall command above:
-x patch_save_files=false
WARNING: If patch_save_files is false when a patch is installed,
the patch cannot be deinstalled. Please be careful
when using this feature.
For future reference, the contents of the PHNE_32825.text file is
available in the product readme:
swlist -l product -a readme -d @ /tmp/PHNE_32825.depot
To put this patch on a magnetic tape and install from the
tape drive, use the command:
dd if=/tmp/PHNE_32825.depot of=/dev/rmt/0m bs=2k
Special Installation Instructions:
1) This patch stops bootpd, but it does not restart after
patch installation, since it is usually invoked by inetd.
Therefore, if bootpd is running in standalone mode
(started manually), customers are advised to manually
restart bootpd after the patch installation.
2) As this patch does not stop the dhcpclient, customers
are advised to restart dhcpclient manually to activate
the patched binary.
i. ps -efx | grep dhcpclient
ii. Kill dhcpclient.
iii. Execute dhcpclient with parameters obtained from
step i.
3) To enable the tftpd service guard fix(CR JAGad25107 /
SR 8606155794), add the "-s" option to the tftp entry in
the "/etc/inetd.conf" file as specified below:
tftp dgram udp wait root /usr/lbin/tftpd tftpd -s
Then, reconfigure inetd using the "inetd -c" command. The
transport patch PHNE_23645 must be installed for proper
functioning of the tftpd service guard fix.
4) To enable the fix for JAGae73843 (SR 8606310985),
include "ncid" tag under the the desired DHCP_DEVICE_GROUP
in /etc/dhcptab configuration file. Note that this
tag should be used for PXE clients ONLY. It SHOULD NOT be
used for normal DHCP clients.
