>/kernel/2.2.19/
where <DIST> is the distribution version of your system (one out of
6.3, 6.4, 7.0 or 7.1).
Most installations are likely to run a k_deflt kernel.
To verify the integrity of the files that you need to download, see the
section "Verification" near the end of this announcement.
In SuSE-6.3 distributions, the above command can produce inconclusive
results. This is caused by a different kernel installation procedure
in this version of the SuSE Linux distribution.
To select your kernel type, choose from the following options:
k_eide - should be used for "exotic" IDE chipsets, mostly found on
additional IDE interface adapters to PCI or ISA bus systems.
k_laptop - should be used for laptops. This kernel has APM support
configured.
k_i386 - a kernel that should run on most i386 processors. Use this
kernel package if the k_pentiu kernel will not boot.
k_smp - kernel for multiprocessor systems (SMP)
k_pentiu - the standard kernel. It should run on most systems.
In the case that you have a self-compiled kernel running on your
system, please note that most kernels for the newer distributions
have APM configured. This obsoletes the need for a particular
laptop kernel. k_deflt (after SuSE-6.3) should do on most modern
hardware.
**** Step 2: SuSE-6.3 special
If you have a SuSE-6.3 system, continue to read this paragraph,
otherwise jump to Step 3.
In SuSE Linux version 6.3, the kernel and the kernel modules are
packaged in two different packages. Both packages must be downloaded
and installed. On SMP systems, the packages kernmods (-> kernmod-SMP)
and k_smp are needed. On single processor systems, get the kernmod
package plus the package as determined by the description in Step 1.
**** Step 3: Installation of the RPM package
Install the rpm package using the command
rpm -Uhv <K_FILE.RPM>
where <K_FILE.RPM> is the rpm package you downloaded in Step 1 (for
6.3 also Step 2, two packages!).
If the RPM command complains about conflicting files or unfulfilled
dependencies, use the options "--nodeps" and "--force". In this case
there is no risk for the consistency of the packages on your system.
**** Step 4: aic7xxx
If you use an Adaptec aic7xxx SCSI host adapter, continue to read
this paragraph, otherwise jump to Step 5.
The new kernel comes with two versions for the Adaptec aic7xxx driver.
If you have such a card, you should see the driver listed in the
output from the command
lsmod
or you should see the adapter in the output of the command
lspci
The new driver is known to work reliably. However, if you encounter
any problems with CDROM drives or other removeable devices (CD-RW
drives, tapes, etc) after this kernel upgrade, then you should try to
use the old driver which is called aic7xxx_old instead of aic7xxx.
If you decide to make this change, then the steps 6 and 7 are
mandatory for the update to succeed, regardless if you get back to
this paragraph after your first reboot or not.
To use the old driver, please use your favourite editor to edit
the file /etc/rc.config. Change aic7xxx into aic7xxx_old at the line
that starts with INITRD_MODULES. You should find it near the top of the
file. Do not forget to save your changes. Then go to Steps 6 and 7.
If you want to use the new driver, then do not change anything.
**** Step 5: LVM
If you use LVM, then continue to read this paragraph,
otherwise jump to Step 6.
If you use LVM (Logical Volume Manager) in your installation of SuSE
Linux, then you need the updated lvm package from the kernel/2.2.19/
directory for your distribution as well. The package contains the
userspace utilities to manage the Logical Volume Manager driver.
An update package is needed because the LVM data format/structure on
disk has changed with the new version of the LVM kernel driver.
Install the package as usual using the command
rpm -Uhv lvm-0.9.1_beta4-12.i386.rpm
Be sure you have downloaded the package for the explicit version
of your SuSE Linux Installation. The package names are identical
for all distribution versions.
WARNING: After the first boot with the new kernel you will not be able
to downgrade to older versions of LVM any more.
**** Step 6: initrd
Upon kernel boot (after lilo runs), the kernel needs to use the
drivers for the device (disk/raid) where the root filesystem
is located. If this driver is not compiled into the kernel, it is
supplied as a kernel module that must be loaded _before_ the
root filesystem is mounted. This is done using a ramdisk that is
loaded along with the kernel by lilo (See next Step).
This ramdisk, called "initrd", must be generated using the command
mk_initrd
The modules as configured in the variable INITRD_MODULES from
/etc/rc.config (See Step 4) are being added to the initrd.
Without the "mk_initrd"-call your system might not boot any more.
**** Step 7: lilo
lilo is responsible for loading the kernel image and the initrd
ramdisk image into the system and for transferring control over the
system to the kernel. Therefore, a proper installation of the
bootloader (by calling the program lilo) is essential for the
system to boot (!).
Manually changed settings in /etc/lilo.conf require the admin to make
sure that /boot/vmlinuz is listed in the first "image" line in that
file. Verify that the line starting with initrd= is set to
initrd=/boot/initrd
Execute
lilo
and you should see your label in an output like
Added linux *
Every other output should be considered an error and requires
attention. If your system managed to reboot before the upgrade, you
should not see any additional output from lilo at this stage.
**** Step 8: SuSE-7.0 special
If you have a SuSE Linux 7.0 distribution, then continue to read this
paragraph, otherwise jump to Step 9.
During testing of the 2.2.19-SuSE Linux kernel, we have found an error
in the glibc (shlibs) package of the SuSE Linux 7.0 distribution. The
error might result in readdir(3) calls to return -EIO to the user
program due to incorrect handling of the return value of getdents(2)
from the kernel. This bug mostly appears on NFS-mounted filesystems
when commands such as tar(1) are used.
We have prepared update packages that solve this specific problem.
Former security updates are included in this package, of course.
Determine which packages you need: See the output of the command
rpm -q shlibs libc libd nssv1
It should not be necessary to update a package that is not installed.
Select the needed update packages and download them from the following
list of URLs
ftp://ftp.suse.com/pub/suse/i386/update/7.0/a1/shlibs-2.1.3-193.i386.rpm
ftp://ftp.suse.com/pub/suse/i386/update/7.0/a1/nssv1-2.1.3-193.i386.rpm
ftp://ftp.suse.com/pub/suse/i386/update/7.0/d1/libc-2.1.3-193.i386.rpm
ftp://ftp.suse.com/pub/suse/i386/update/7.0/d2/libd-2.1.3-193.i386.rpm
!!! !!! WARNING: !!! !!!
After download and before installation of the glibc packages, the
system should be brought to single user mode ("init 1"). If this
is not suitable for operational reasons, then please keep the system
as calm as at all possible during the update of the shlibs and nssv1
packages. In particular, do not run any shell scripts or any other
processes that execute other binaries. Stop the cron and at services,
and shut down your MTA. Suspend the execution of active processes
by killing them with the -STOP signal and let them resume their work
after the installation of the shlibs and nssv1 packages with a -CONT
signal.
After verifying that the right conditions are in place, install the
packages using the command
rpm -Fhv nssv*.rpm shlibs*.rpm
rpm -Fhv <rest>
Afterwards, execute the command
ldconfig
to update the cache for the dynamic linker.
NOTE: updating shared libraries in the running system requires enough
space on the root and /usr filesystem to keep both versions of the
shared libraries on the disk. The old libraries will be deleted, but
the files continue to use diskspace until they are not used by any
processes any more. (See Step 9). Similar considerations apply for the
the memory consumption of the system.
**** Step 9: reboot
Reboot your machine for the new kernel to boot and therefore become
active. Make sure that all of the above steps have completed
successfully. Shutdown and reboot using the command
shutdown -r now
or
init 6
Notes:
a) After the upgrade, you might notice kernel messages upon execution
of an NFS mount command:
silence kernel: nfs warning: mount version older than kernel
These messages are complaints that the mount(8) command needs to
be upgraded. The mount(8) command is contained in the package
"util" ("util-linux" for SuSE-7.1) - we will provide update
packages for the "util" ("util-linux" for SuSE-7.1) package.
The change is mostly a cosmetic nature and does not have any
impact on the security or the stability of the system.
b) The kernel sources are contained in the RPM
kernel/2.2.19/lx_sus22-2.2.19.SuSE-25.i386.rpm in each distribution
update tree. The kernel documentation is in the package
kernel/2.2.19/lx_doc22-2.2.19.SuSE-25.i386.rpm and installs to the
base path /usr/share/doc/kernel/.
c) The directory kernel/misc/ in each distribution tree contains
the .config files, the spec and changes file as well as the
compilation output for the respective kernel, each in a directory
where it belongs to. In addition, the sources for the lvm
package can be found in the lvm directory as appropriate.
Known problems:
* The kernel modules for the cipe and the freeswan packages are not
contained in the kernel RPM packages. If you use these packages, then
you should wait with the kernel update until the kernel modules
for these packages are available, or you could recompile the kernel
modules yourself (See section Notes b). Please read the section 2)
of the upcoming SuSE security announcements for the location of the
cipecb.o and ipsec.o kernel modules.
Verification:
All RPM packages are gpg-signed using the build@suse.de SuSE packaging
key that can be found in the toplevel directory of the first CD on
SuSE-7.1 and younger, as well as at
ftp://ftp.suse.com/pub/suse/pubring.gpg-build.suse.de (this key is signed
by security@suse.de).
All files that are needed or referred to in this announcement have
their md5 sums listed in the file
ftp://ftp.suse.com/pub/suse/i386/update/>/kernel/MD5SUMS .
These files are signed by security@suse.de in the file MD5SUMS.sig.
Since there are 150 files, we do not send the md5sums with the mail
this time.
