Patch Name: PHKL_7059 Patch Description: s700 10.01 Fix for file lock starting at 2GB-1 Creation Date: 96/05/24 Post Date: 96/05/31 Hardware Platforms - OS Releases: s700: 10.01 Products: N/A Filesets: OS-Core.CORE-KRN Automatic Reboot?: Yes Status: General Release Critical: No Path Name: /hp-ux_patches/s700/10.X/PHKL_7059 Symptoms: PHKL_7059: fcntl() did not handle the lock request start=2GB-1 len=0 properly and multiple processes could get the lock. Defect Description: PHKL_7059: The fcntl() lock request start=2GB-1 len=0 always succeeded, and thus multiple processes could get this lock. Also, an explicit unlocking (F_UNLCK) would not remove the lock from the lock list, although the implicit unlocking done at close time would remove the lock.

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 PHKL_7059 5a. For a standalone system, run swinstall to install the patch: swinstall -x autoreboot=true -x match_target=true \ -s /tmp/PHKL_7059.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/PHKL_7059.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. The cluster clients must be shut down as described in step 5b. By default swinstall will archive the original software in /var/adm/sw/patch/PHKL_7059. 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 PHKL_7059.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/PHKL_7059.depot of=/dev/rmt/0m bs=2k Special Installation Instructions: None
