Scientific Linux 4.3 Release Notes

  ---------------------------------------------------------------------------

Introduction

  The following topics are covered in this document:

    o Changes to the Scientific Linux installation program
      (Anaconda)

    o General information

    o Kernel Notes

    o Changes to drivers and hardware support

    o Changes to packages

Installation Related Notes

  The following section includes information specific to installation of
  Scientific Linux and the Anaconda installation program.

 Note

  In order to upgrade an already-installed Scientific Linux 4x system
  to 4.3, you must use yum to update those packages that have changed.
  Instructions can be found at
  https://www.scientificlinux.org/documentation/howto/upgrade.4x

  You may use Anaconda to perform a fresh installation of Scientific
  Linux 4.3 or to perform an upgrade from Scientific Linux 30x to
  Scientific Linux 4.3.

    o The Scientific Linux 4.3 installation program terminates with
      the error "install exited abnormally -- received signal 11" early in
      the installation process if a Sony PCGA-CD51 external PCMCIA CD-ROM
      drive is connected.

      There are two workarounds for this issue:

        1. If you are using the drive as the installation source, add the
           following options at the installation boot prompt:

pci=off ide1=0x180,0x386

        2. If you are not using the drive as the install source, either
           disconnect it before attempting the installation or add the
           following option at the installation boot prompt:

nopcmcia

    o Installation of Scientific Linux 4.3 is known to have
      an issue with USB peripherals on IBM(R) BladeCenter(R) HS20-8832
      systems.

      To avoid this issue, you must perform either of two actions:

         o Install Scientific Linux 4.3 x86_64

         o If you are installing Scientific Linux 4.3 for the
           x86 architecture, you must first move the USB IRQ from line #7 to
           another available IRQ line. This will prevent stray interrupts
           from disrupting the USB device and the installation of the OS.
           Consult your hardware vendor for more information about changing
           IRQ lines in your system.

General Information

  This section contains general information not specific to any other
  section of this document.

    o The InfiniBand Architecture (IBA) is an industry standard that defines
      a new high-speed, switched fabric subsystem designed to connect
      processor nodes and I/O nodes to form a system area network. This new
      interconnect method transitions from a local transaction-based I/O
      model across buses to a remote message-passing model across channels.

      Scientific Linux 4.3 includes a technology preview
      release of the upstream OpenIB.org InfiniBand network and clustering
      software implementation.

      Note that this technology preview release is not supported for use in
      production environments, and that the OpenIB InfiniBand interfaces and
      APIs are subject to change during the technology preview phase. Not
      all of the InfiniBand upper layer protocols are implemented in the
      current upstream OpenIB project. As more upper layer protocols are
      implemented by the OpenIB group, a fully supported release of the
      OpenIB InfiniBand network/clustering stack is planned.

      InfiniBand technologies implemented via new or updated packages in
      this preview are as follows:

         o kernel -- Low level driver support for Mellanox based host
           controllers are included. The core InfiniBand modules are also
           included, which provide the interface between the low level
           hardware driver and the upper layer InfiniBand protocol drivers
           and also provide user space access to InfiniBand hardware. Also
           included are the Sockets Direct Protocol (SDP) upper layer kernel
           driver, the IP over InfiniBand (IPoIB) TCP/IP networking protocol
           driver, and the SCSI Remote Direct Memory Access (RDMA) protocol
           driver.

         o udev - Minor modifications were made to know where to place the
           new InfiniBand device files

         o initscripts -- Added a new ifup-ib network script to enable using
           IPoIB networking at boot time.

         o module-init-tools -- Minor modifications were made to support the
           new SDP socket protocol and IPoIB interfaces

         o libibverbs -- A library that provides direct user space access to
           the RDMA verbs capabilities of InfiniBand hardware. Developers
           who want to program to the verbs interface can program to the
           libibverbs API and, as new hardware support is added, their
           application will require no modifications.

         o libmthca -- A low level hardware driver library that plugs into
           libibverbs and actually communicates with the hardware on behalf
           of libibverbs. Support for future hardware will be implemented as
           additional libraries.

         o libsdp -- An LD_PRELOAD supported library that allows users to
           cause their existing TCP/IP network applications to use SDP
           instead without the need to recompile their application

         o opensm -- The Open Subnet Manager. At least one machine in any
           InfiniBand network must be running a subnet manager in order to
           configure the low level hardware link routing. This is usually
           left running as a system daemon to handle reconfiguration of the
           subnet fabric on link status change events.

         o udapl -- The User Direct Access Programming Library is a high
           level user space RDMA programming environment. The uDAPL library
           allows applications to take advantage of RDMA protocols without
           having to be aware of how to program the RDMA capable hardware.
           The uDAPL specification is not InfiniBand specific, and in the
           future should support RDMA hardware other than InfiniBand, such
           as RDMA enabled 10-Gigabit Ethernet controllers.

           To use the udapl library, you must make sure that the libdat.so
           file is in the path. This can accomplished by adding the
           following line to the /etc/ld.so.conf file:

/usr/lib64/dat

           Additionally, by default, the system parameters are set to allow
           only a minimum amount of memory to be locked down by user-mode
           applications, such as uDAPL. To increase this limit, you must
           modify the parameters in /etc/security/limits.conf to increase
           the amount of memory allowed for memlock.

           For example, on a system with 1 gigabytes of memory, a system
           administrator may allow 1 gigabyte to be locked down via memlock.
           To allow this, the administrator would add the following in the
           /etc/security/limits.conf file.

*                hard    memlock          1000000
*                soft    memlock          1000000

    o There is a change in the behavior of /etc/issue and /etc/issue.net in
      the sl-release package, such that user-customized versions of
      these files are not moved to a new filename (/etc/issue.rpmsave and
      /etc/issue.net.rpmsave, respectively) when sl-release is updated.

      Because of the triggers that exist in previous sl-release RPMs,
      the change in behavior will not take effect when the package is first
      updated. What will happen is that the new /etc/issue and
      /etc/issue.net files from the updated sl-release package will be
      saved as they are on disk and any previously customized /etc/issue and
      /etc/issue.net files will get moved to /etc/issue.rpmsave and
      /etc/issue.net.rpmsave, respectively. Users must reapply their
      customizations to these files one time. After reapplying their
      customizations to the files, subsequent upgrades will update as
      expected without such user intervention.

    o Scientific Linux 4.3 supports a new feature to access
      z/VM hypervisor commands (CP commands) using a new Linux kernel module
      called vmcp.ko and a new tool called vmcp. This new feature allows
      Linux guests to be managed running under z/VM out of a z/VM guest
      running a Scientific Linux 4.3 image.

    o DebugInfo packages provide full debugging symbol binaries for
      individual package libraries so that system analysis tools and
      profilers can fully debug and trace applications. DebugInfo packages
      install these binaries in the directory /usr/lib/debuginfo.

      With the -debuginfo RPMs installed, users are able to fully take
      advantage of the following deep analysis tools:

         o Program debugging with gdb

         o kernel core dump debugging with crash

         o performance analysis and profiling with systemtap and oprofile

      DebugInfo packages for Scientific Linux 4x are available from
      the Scientific Linux FTP site at the following URLs:

ftp://ftp.scientificlinux.org/linux/scientific/4x/archives/debuginfo/i386
ftp://ftp.scientificlinux.org/linux/scientific/4x/archives/debuginfo/x86_64
ftp://ftp.scientificlinux.org/linux/scientific/4x/archives/debuginfo/ia64

    o Scientific Linux 4.3 includes a technology preview
      release of Frysk, a new execution analysis framework. Users are
      encouraged to find more information and provide feedback on the
      technology preview at the Frysk project web site:

      [3]http://sources.redhat.com/frysk/

      Note that this technology preview release of Frysk is not supported
      for use in production environments, and that Frysk interfaces and APIs
      are subject to change during the technology preview phase. A fully
      supported release of Frysk is planned for future releases of
      Scientific Linux.

Kernel Notes

  This section contains notes relating to the Scientific Linux 4.3 kernel.

    o Scientific Linux 4.3 includes the largesmp kernel
      package for 64-bit platforms. In order to preserve the kernel
      application binary interface (kabi) in current supported kernels,
      Scientific Linux introduces a new kernel package called
      kernel-largesmp-2.6.9-xxx.EL.yyy.rpm.

      xxx specifies the kernel version, while yyy specifies the platform
      name, which is one of the following 3 platforms: x86_64, ia64, ppc64.

      The largesmp kernel on AMD64 and Intel(R) EM64T platforms increases
      support of CPUs from 8 to 64.

      With successful partner collaboration and testing of the largesmp
      kernel in Scientific Linux 4.3, the supported and
      certifiable CPU limits for AMD64/EM64T, Itanium2, and POWER will
      increase in future releases.

    o The largesmp kernels introduced in Scientific Linux 4.3
      support up to 128GB of memory.

    o Files and directories have permission sets for the owner of the file,
      the group associated with the file, and all other users for the
      system. However, these permission sets have limitations. For example,
      different permissions cannot be configured for different users. To
      address this need, Access Control Lists (ACLs) were implemented.

      The Scientific Linux 4.3 kernel provides ACL support
      for the ext3 file system and NFS file systems. ACLs are now recognized
      on ext3 file systems accessed via Samba.

      Along with support in the kernel, the acl package is required to
      implement ACLs. The acl package contains the utilities used to add,
      modify, remove, and retrieve ACL information.

    o Scientific Linux 4.3 adds error detection and
      correction (EDAC) functionality for x86 and x86_64 systems. The
      kernel, on supported chipsets, can now detect and report ECC single
      bit errors, and report and panic on multi-bit errors.

      The behavior of the kernel is controlled by
      /proc/sys/kernel/panic_on_unrecovered_nmi; and the default value is
      set to "1". If an unrecoverable ECC error or unknown non-maskable
      interrupt (NMI) is detected and the value of
      /proc/sys/kernel/panic_on_unrecovered_nmi is set to "1", then the
      kernel will panic and halt the system. This is the default behavior.

      The hardware autodetect program automatically detects and loads the
      appropriate EDAC kernel modules during installation or upgrade. Upon
      successful loading of the modules, some kernel messages will be saved
      in the message log file.

      While EDAC kernel modules are loaded, the kernel provides control
      interfaces to perform debugging and logging at run-time via
      /proc/sys/mc and directory assistance via the /proc/mc directory.

      If the EDAC kernel modules are loaded, then the kernel provides
      control interfaces to perform debugging and logging at run-time via
      /proc/sys/mc and directory assistance via the /proc/mc directory.

      The EDAC code in Scientific Linux 4x and the code it is based
      on provide statistics via /proc. As part of the merger and acceptance
      of this code into the base kernel, this interface will change to use
      sysfs. Customers should expect future Scientific Linux releases
      to adopt the sysfs interface instead.

    o Kernel Key Management support was a new feature included in
      Scientific Linux 4.2. However, due to on-going development
      efforts, be advised that Kernel Key Management is a technology preview
      and that the key management interfaces can and will undergo further
      development in subsequent Scientific Linux 4x updates. Because
      Kernel Key Management is a technology preview, it is not supported for
      production environments.

Changes to Drivers and Hardware Support

  This update includes bug fixes for a number of drivers. The more
  significant driver updates are listed below.

    o The following device drivers are added or updated in
      Scientific Linux 4.3:

         o added support for Marvell Yukon 2 chipset in sky2 driver

         o added support for SysKonnect's SK-9E21, SK-9S21 chipset in sky2
           driver

         o added support for LSI Logic MegaRAID Serial Attached SCSI
           (megaraid_sas) driver

         o incorporated Broadcom NetXtreme II (bnx2) network driver with
           support for BCM5706 and BCM5708

         o added support for HT1000 chipset in serverworks driver

         o added support for HT2000 chipset in serverworks driver

         o updated Emulex LightPulse Fibre Channel (lpfc) driver

         o updated Intel(R) PRO/1000 (e1000) networking driver

         o updated HP Smart Array (cciss) driver

         o updated LSI Logic MPT Fusion driver

         o updated QLogic Fibre Channel (qla2xxx) driver

         o updated Adaptec RAID (aacraid) driver

         o updated Broadcom Tigon 3 (tg3) network driver

         o various SATA driver updates

    o The SysKonnect Yukon II (sky2) driver is now available in
      Scientific Linux 4.3. It only supports hardware that is not
      supported by the sk98lin driver in Scientific Linux 4.3.
      Note that the current version of the sky2 driver is known to
      perform poorly if autonegotiation is disabled.

    o Support for fabric rediscovery through sysfs is now available in
      Scientific Linux 4.3. For the Qlogic (qla2xxx) and Emulex
      (lpfc) Fibre Channel HBA drivers, run the following commands to
      perform redisocvery and rescan for new storage:

echo "1" > /sys/class/fc_host/hostXYZ/issue_lip
echo "- - -" > /sys/class/scsi_host/hostXYZ/scan

      Where XYZ is the scsi host number of your HBA.

    o The Scientific Linux 4x release notes mentioned several issues
      related to the Emulex LightPulse Fibre Channel driver (lpfc). All of
      these issues (related to cable pulls, rmmod and insmod) were fixed in
      Scientific Linux 4.1. The lpfc driver was included in
      the upstream Linux 2.6 kernel shortly after Scientific Linux 4.0
      shipped. Scientific Linux fully supports the lpfc driver, and is committed to
      maintaining the driver as long as Scientific Linux 4x is
      supported.

    o In some Fibre Channel configurations, an operating system will
      automatically detect the addition of a new target device while the
      system is running. In other configurations, it is necessary to issue
      the following command to detect a new target device:

echo 1 > /sys/class/fc_host/hostn/issue_lip

      Where hostn corresponds to the appropriate adapter.

      When a new Logical Unit is created on a particular target, a command
      such as the following is required to detect and configure it:

echo "b t l" > /sys/class/scsi_host/hostn/scan

      Where b is the bus, t is the target, and l is the LUN to be scanned on
      hostn.

      Wild cards can also be used, such as the following example:

echo "- - -" > /sys/class/scsi_host/host2/scan

      Note that the device name (such as /dev/sdb) that is assigned when a
      device is added dynamically while the system is running may be
      different from the device name assigned the next time the system
      boots.

    o Scientific Linux 4.3 includes support for scanning past
      LUN 0 when a target returns a peripheral qualifier of 3 for LUN 0. For
      SCSI 3 and higher devices, the scsi layer will attempt a REPORT_LUNS
      command, and for SCSI 2 devices the scsi layer will perform a
      sequential scan for LUNs 1 to 7.

      To modify the scanning behavior, users can add entries to the scsi
      device_info table through the procfs interface located at
      /proc/scsi/device_info or through the scsi_mod module parameters. The
      format for the entry is dev_flags=vendor:model:flags[,v:m:f] where
      flags can be the following integer values:

0x001   /* Only scan LUN 0 */
0x002   /* Known to have LUNs, force scanning, deprecated: Use max_luns=N */
0x004   /* Flag for broken handshaking */
0x008   /* unlock by special command */
0x010   /* Do not use LUNs in parallel */
0x020   /* Buggy Tagged Command Queuing */
0x040   /* Non consecutive LUN numbering */
0x080   /* Avoid LUNS >= 5 */
0x100   /* Treat as (removable) CD-ROM */
0x200   /* LUNs past 7 on a SCSI-2 device */
0x400   /* override additional length field */
0x800   /* ... for broken inquiry responses */
0x1000  /* do not do automatic start on add */
0x2000  /* do not send ms page 0x08 */
0x4000  /* do not send ms page 0x3f */
0x8000  /* use 10 byte ms before 6 byte ms */
0x10000 /*  192 byte ms page 0x3f request */
0x20000 /* try REPORT_LUNS even for SCSI-2 devs (if HBA supports more than 8 LUNs) */
0x40000 /* don't try REPORT_LUNS scan (SCSI-3 devs) */
0x80000 /* don't use PREVENT-ALLOW commands */
0x100000 /* device is actually for RAID config */
0x200000 /* select without ATN */
0x400000 /* retry HARDWARE_ERROR */

      For example, to scan past LUN 7 for a SCSI 2 device from vendor Linux
      with model scsi_debug, execute the following command:

echo Linux:scsi_debug:200 > /proc/scsi/device_info

      or

modprobe scsi_mod dev_flags=Linux:scsi_debug:200

      The module parameter can also be added to /etc/modprobe.conf so that
      it can be used at system boot-up:

options scsi_mod dev_flags=Linux:scsi_debug:200
