Patch Description: s700 10.20 VME Services Patch

Creation Date: 97/06/02

Post Date:  97/06/10

Hardware Platforms - OS Releases:
        s700: 10.20

Products: N/A

Filesets:
        VME-Services.VME-KRN

Automatic Reboot?: No

Status: General Superseded

Critical: No

Path Name:  /hp-ux_patches/s700/10.X/PHKL_11224

Symptoms:
        PHKL_11224:
        1) Use of system V shared memory shmat() or
           file based shared memory mmap() call will cause
           the vme2_ioctl() command VME2_USER_COPY to fail.
        2) vme_dma_setup() may cause VME bus errors if invoked
           with the VME_USE_IOMAP option active.
        3) VME2_USER_COPY transfers the SAME 256k bytes for data
           transfers larger than 256K.
        4) VME_USER_COPY does not limit transfers to MAXPHYS length

Defect Description:
        PHKL_11224:
        1) VME Services makes invalid assumptions about kernel
           space id values with respect to shared memory, not
           exposed until shared memory used in a 10.X environment.
        2) Detected at 9.05 ( but problem is present at 10.X).
           VME Services does not lock VME bus when accessing
           slave mapper configuration registers in vme_dma_setup().
           Failure to do this may cause bus errors.
        3) Kernel data pointer not properly updated
        4) Incorrect checking for MAXPHYS.

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 PHKL_11224

        5a. For a standalone system, run swinstall to install the
            patch:

                swinstall -x autoreboot=true -x match_target=true \
                        -s /tmp/PHKL_11224.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_11224.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/PHKL_11224.  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_11224.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_11224.depot of=/dev/rmt/0m bs=2k
