Patch Name: PHNE_12522 Patch Description: s700_800 10.20 2.23 ACC X.25 Protocol Software (EISA) Patch Creation Date: 97/09/13 Post Date: 97/09/23 Hardware Platforms - OS Releases: s700: 10.20 s800: 10.20 Products: Z7401A 2.23; Z7434AA 2.23; Filesets: ACC-X25.ACC-X25-KRN Automatic Reboot?: Yes Status: General Superseded Critical: No Path Name: /hp-ux_patches/s700_800/10.X/PHNE_12522 Symptoms: PHNE_12522: SR None / DTS None: Fix some general problems discovered in the handling of the Fast-Select and Call/Clear user data. SR None / DTS None: Fix a potential hang in PVC setups if a Reset Collision occurs. SR None / DTS None: Fix a defect introduced in the PVC close handling. SR None / DTS None: Fix a configuration problem with one-way SVCs when an unequal number of SVC INs vs OUTs are defined and the link is configured as a DCE. PHNE_12223: SR None / DTS None: Enhancement patch erroneously submitted. Patch recalled. PHNE_12094: SR None / DTS None: Reset packets that omit the diagnostic code are rejected with a packet too short error. PHNE_11869: SR 5003379479 / DTS TPO0h01476: When using negotiated packet or window sizes, then the called and calling direction sense of the negotiated parameters is reversed. The facilities field in the call packet is formatted correctly. The error is only noticeable when the ACC is not connected to another ACC card and the negotiated values are asymmetric (not the same in each direction). The error can lead to RESETS on SVCs, with diagnostic errors indicating bad P(r), bad P(s) or packet size errors. SR None / DTS None: Restart packets that omit the diagnostic code are rejected with a packet too short error. PHNE_11434: SR None: Problem in clearing SVCs; they get into an incorrect state. Problem for inbound calls, not for outbound calls because of queuing on inbound calls. PHNE_11283: SR 4701356246 "Application timeout on inbound call" error in the ZCOM logfile SR 4701356253 SVCs could be left around instead of cleaned up. PHNE_11025: SR None / DTS TPO0h01163: When using the X.121 address information supplied in the TTGEN configuration on an outbound call request (ZCOM API only), both the calling and called addresses transmitted in the call packet were the same. They both coresponded to the X.121 address configured for the link. SR 4701349134 / DTS TPO0h01160: If call user data is supplied in the TTGEN configuration file for a SVC and the user request the TTGEN call user data be sent in the call, the call user data was not being inserted into the call request packet. Defect Description: PHNE_12522: SR None / DTS None: There were missing checks in the Clear Request handling for "Fast-Select" and in the Call Accept handling for "Restricted Fast-Select". Call user data is not allowed in these cases. SR None / DTS None: When a Reset Collision occurred, a Reset Complete unsolicited status message was not being sent to the upper layers. SR None / DTS None: There was a missing check when disabling PVCs on a close. SR None / DTS None: The LCN subscription table is defined from the perspective of the DTE, but the ZLUs are always created from the local perspective. For DCEs, the number of input and output one-way SVCs created needed to be reversed. PHNE_12223: SR None / DTS None: Enhancement patch erroneously submitted. Patch recalled. PHNE_12094: SR None / DTS None: Under ISO 8208 the diagnostic code for restarts and resets is mandatory. However, under ITU-T X.25, it is optional. The ACC implementation was treating the diagnostic code as mandatory. PHNE_11869: SR 5003379479 / DTS TPO0h01476: Incorrect parsing of the packet size and window size facilities fields. SR None / DTS None: Under ISO 8208 the diagnostic code is mandatory. However, under ITU-T X.25, it is optional. The ACC implementation was treating the diagnostic code as mandatory. PHNE_11434: SR None: This is a follow-up fix to the last superseded patch. Fix for a fix to an ENOSPC problem in axin. PHNE_11283: SR 4701356246 zx25 driver was clearing a call when the call did not have to be cleared. SR 4701356253 zx25 driver call accept did not correctly check state of the circuit. PHNE_11025: SR None / DTS TPO0h01163: When using the TTGEN supplied X.121 addresses, the driver copies the address into temporary variables (addr1 and addr2) and assigns pointer for the called and calling address to these temporaries. However, the code was assigning both the called and calling pointers to the same temporary (addr1) which resulted in both addresses being the same. SR 4701349134 / DTS TPO0h01160: The code to retrieve the call user data from the SVC's table area was incorrect.

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_12522 5a. For a standalone system, run swinstall to install the patch: swinstall -x autoreboot=true -x match_target=true \ -s /tmp/PHNE_12522.depot 5b. For a homogeneous NFS Diskless cluster run swcluster on the server to install the patch on the server and the clients: swcluster -i -b This will invoke swcluster in the interactive mode and force all clients to be shut down. WARNING: All cluster clients must be shut down prior to the patch installation. Installing the patch while the clients are booted is unsupported and can lead to serious problems. The swcluster command will invoke an swinstall session in which you must specify: alternate root path - default is /export/shared_root/OS_700 source depot path - /tmp/PHNE_12522.depot To complete the installation, select the patch by choosing "Actions -> Match What Target Has" and then "Actions -> Install" from the Menubar. 5c. For a heterogeneous NFS Diskless cluster: - run swinstall on the server as in step 5a to install the patch on the cluster server. - run swcluster on the server as in step 5b to install the patch on the cluster clients. By default swinstall will archive the original software in /var/adm/sw/patch/PHNE_12522. If you do not wish to retain a copy of the original software, you can create an empty file named /var/adm/sw/patch/PATCH_NOSAVE. Warning: If this file exists when a patch is installed, the patch cannot be deinstalled. Please be careful when using this feature. It is recommended that you move the PHNE_12522.text file to /var/adm/sw/patch for future reference. To put this patch on a magnetic tape and install from the tape drive, use the command: dd if=/tmp/PHNE_12522.depot of=/dev/rmt/0m bs=2k Special Installation Instructions: SUBSYSTEM_SHUT Before installing this patch, use the following command to shutdown the ACC subsystem and kill the ACC daemons. /opt/acc/bin/zmasterd kill The above command kills any of the ACC daemons that are still running, including zmasterd, zx25d, watch, zmlog, zmon, and znode. The kernel will be regenerated and the system will reboot automatically during the patch installation.
