The following topics are covered in this document:
Changes to the Red Hat Enterprise Linux installation program (Anaconda)
General information
Kernel-related information
Changes to drivers and hardware support
Changes to packages
The following section includes information specific to the Red Hat Enterprise Linux installation program, Anaconda.
In order to upgrade an already-installed Red Hat Enterprise Linux 3 system to Update 3, you must use Red Hat Network to update those packages that have changed. The use of Anaconda to upgrade to Update 3 is not supported.
Use Anaconda only to perform a fresh install of Red Hat Enterprise Linux 3 Update 3.
If you are copying the contents of the Red Hat Enterprise Linux 3 Update 3 CD-ROMs (in preparation for a network-based installation, for example) be sure you copy the CD-ROMs for the operating system only. Do not copy the Extras CD-ROM, or any of the layered product CD-ROMs, as this will overwrite files necessary for Anaconda's proper operation.
These CD-ROMs must be installed after Red Hat Enterprise Linux has been installed.
This section contains general information not specific to any other section of this document.
Red Hat Enterprise Linux 3 Update 3 adds the most recent version of the KornShell (ksh) to the Red Hat Enterprise Linux Extras CD. KornShell is a shell programming language for both interactive and shell script use, and is upward compatible with the Bourne Shell (sh).
The new ksh package is an optional alternative to pdksh, which is already included in the core distribution. It is useful in circumstances where precise compatibility with AT&T ksh semantics is required.
The autofs package, which controls the operation of the automount daemons running on Red Hat Enterprise Linux, has been updated to version 4. This update provides full backward compatibility with version 3. Additionally, it adds the following features:
Browsable mounts (ghosting) — Ghosting of map directories allows you to see the directories in the autofs map without mounting them. When they are accessed (such as when a directory listing is requested) the map entry is mounted so that it is seen.
Replicated Server support — Replicated server functionality allows the administrator to specify map entries that point to multiple, replicated servers. The automount daemon attempts to determine the best server to use for mounts by testing the latency of an rpc_ping to each available server. Weights may also be assigned to the servers, allowing for more administrator control. Refer to the /usr/share/doc/autofs-4.1.3/README.replicated-server file for additional map format information.
Executable maps — A map can now be marked as executable. The initscript that parses the auto.master map passes this as a program map to the auto-mounter. A program map is called as a script with the key as an argument. It may return no lines of output if there is an error, or one or more lines containing a map (with \ quoting line breaks). This feature is useful for implementing /net functionality.
Multi-mounts — This feature allows the automount daemon to seek multiple lookup methods in succession. For example, a lookup could query NIS and file maps.
Red Hat Enterprise Linux 3 Update 2 is currently "in evaluation" for Evaluated Assurance Level (EAL) 3+/Controlled Access Protection Profile (CAPP) on the following platforms:
Red Hat Enterprise Linux WS on the x86 architecture
Red Hat Enterprise Linux AS on the x86, AMD64, IBM zSeries, iSeries, and pSeries architectures
To get the latest Common Criteria evaluation status, refer to the following Web page:
http://www.redhat.com/solutions/industries/government/commoncriteria/
All the patches that were applied to the Red Hat Enterprise Linux 3 Update 2 code base to achieve EAL3 certification have been mirrored in the Red Hat Enterprise Linux 3 Update 3 release.
For additional information regarding the auditing subsystem, refer to the laus(7) man page.
Since its initial deployment in the Red Hat Enterprise Linux 3 Update 2 kernel, the kernel for Update 3 contains additional modifications that enable system-call auditing on additional architectures. When auditing is not in use, these modifications are performance-neutral. The kernel component provides access to the auditing facilities through the character-special device /dev/audit. Through this device, a user-space daemon (auditd) can enable or disable auditing and can provide the kernel with the rulesets to be used to determine when a system-call invocation must be logged. This device is also used by auditd to retrieve audit records from the kernel for transfer to the audit log. Refer to the audit(4) man page for information concerning supported ioctl calls and /proc/ interfaces for managing and tuning auditing behavior.
The iSeries ODBC Driver for Linux product has been replaced by a new product — iSeries Access for Linux. This new product is available as a Web download:
http://www.ibm.com/eserver/iseries/access/linux/
iSeries Access for Linux is the latest offering in the iSeries Access product line. It offers Linux-based access to iSeries servers. iSeries Access for Linux allows you to access the DB2 Universal Database® (UDB) for iSeries using its ODBC Driver and to establish a 5250 session to an iSeries server from a Linux client.
The version of the httpd Web server included as part of Red Hat Enterprise Linux 3 Update 3 includes several significant changes:
The mod_cgi module has been enhanced to correctly handle concurrent output on stderr and stdout
SSL environment variables defined by mod_ssl can be used directly from mod_rewrite using the %{SSL:...} syntax. For example, "%{SSL:SSL_CIPHER_USEKEYSIZE}" may expand to "128".
Similarly, SSL environment variables can be used directly from mod_headers using the %{...}s syntax.
The mod_ext_filter module is now included
The minimal acceptable group id that will be used by suexec has been lowered from 500 to 100. This allows the use of suexec with users belonging to the "users" group.
This section contains information related to the Red Hat Enterprise Linux 3 Update 3 kernel.
Red Hat Enterprise Linux 3 Update 3 includes preliminary support for initial IBM POWER5 platforms, and includes the following features:
Support for micropartitioning, with up to 254 partitions per system enabling a low-cost solution for server consolidation.
Simultaneous multithreading for increased performance.
Virtual storage, which allows multiple partitions within a POWER5-based system to share storage. Virtual adapters allow other partitions (I/O client partitions) to use storage from the I/O server partition.
Virtual LAN, which provides a fast and cost-effective way for partitions to communicate with each other over the physical or virtual LAN.
The ipr device driver for the IBM Power RAID SCSI adapters default the maximum SCSI speed to 80 MB/s. In order to enable U160 or U320 SCSI speeds, download and install the latest microcode image for your SCSI adapter from this page:
http://techsupport.services.ibm.com/server/mdownload/download.html
Run iprupdate to update the microcode on the adapter and enable faster SCSI speeds. Note that iprupdate must be run each time the system is booted (or each time the ipr device driver is loaded) to enable optimal transfer rates. An init.d script is installed as part of the iprutils package that will ensure iprupdate is run each time the system is booted.
This update includes bug fixes for a number of drivers. The more significant driver updates are listed below. In some cases, the original driver has been preserved under a different name, and is available as a non-default alternative for organizations that wish to migrate their driver configuration to the latest versions at a later time.
The migration to the latest drivers should be completed before the next Red Hat Enterprise Linux update is applied, because in most cases only one older-revision driver will be preserved for each update.
These release notes also indicate which older-revision drivers have been removed from this kernel update. These drivers have the base driver name with the revision digits appended; for example, megaraid_2002.o. You must remove these drivers from /etc/modules.conf before installing this kernel update.
Keep in mind that the only definitive way to determine what drivers are being used is to review the contents of /etc/modules.conf. Use of the lsmod command is not a substitute for examining this file.
Adaptec RAID (aacraid driver)
The aacraid driver has been updated from 1.1.2 to 1.1.5-2339
The new driver is scsi/aacraid/aacraid.o
The older driver has been preserved as addon/aacraid_10102/aacraid_10102.o
LSI Logic RAID (megaraid driver)
The megaraid2 driver includes support for a number of new host bus adapters (certain PERC4 and Serial ATA products) that are not supported by the megaraid driver. If your system contains these newer products exclusively, the megaraid2 driver is loaded by default. If you have the older products exclusively, the megaraid driver will continue to be the default.
However, if you have a mix of old and new MegaRAID adapters, then the driver that is selected depends on the order in which the adapters are scanned. (Note that you cannot have both the megaraid and megaraid2 drivers loaded at the same time.) If the default driver on your system is not the desired one, take one of the following actions:
If you are installing the system, type the following command at the boot prompt:
expert noprobe
Next, select the desired driver from the subsequent menu.
If the system is already installed, edit /etc/modules.conf and change the "alias scsi_hostadapter" lines referring to the megaraid or the megaraid2 driver to the desired driver. Note that after making any changes to /etc/modules.conf you must rebuild the initrd image; refer to the mkinitrd man page for further details.
The megaraid2 driver has been updated from v2.10.1.1 to v2.10.6-RH1
The new driver is scsi/megaraid2.o
The older driver has been preserved as addon/megaraid_2101/megaraid2101.o
The v2.00.9 driver has been removed
The default driver remains the v1.18k driver (megaraid.o)
IBM ServeRAID (ips driver)
The ips driver has been updated from 6.11.07 to 7.00.15
The new driver is scsi/ips.o
The older driver has been preserved as addon/ips_61107/ips_61107.o
The ips 6.10.52 driver (ips_61052.o) has been removed
LSI Logic MPT Fusion (mpt* drivers)
These drivers have been updated from 2.05.11.03 to 2.05.16
The new drivers are located in message/fusion/
The older drivers have been preserved in addon/fusion_20511
The 2.05.05+ drivers (mpt*_20505.o) have been removed
Compaq SA53xx Controllers (cciss driver)
The cciss driver has been updated from 2.4.50.RH1 to v2.4.52.RH1
QLogic Fibre Channel (qla2xxx driver)
These drivers have been updated from 6.07.02-RH2 to 7.00.03-RH1
The new drivers are located in addon/qla2200
The older driver has been preserved in addon/qla2200_60702RH2
The 6.06.00b11 drivers (qla2*00_60600b11.o) have been removed
The QLA2100 adapter has been retired by QLogic. This adapter is no longer supported by QLogic or Red Hat. Therefore, the driver is located in the kernel-unsupported package.
Emulex Fibre Channel (lpfc driver)
This driver has been added to the distribution. The version is 7.0.3
The driver is located in addon/lpfc
Intel PRO/1000 (e1000 driver)
This driver has been updated from 5.2.30.1-k1 to 5.2.52-k3
Intel PRO/100 (e100 driver)
This driver has been updated from version 2.3.30-k1 to 2.3.43-k1
Broadcom Tigon3 (tg3 driver)
This driver has been updated from v3.1 to v3.6RH
