solutions Security update for Linux kernel SuSE Linux Maintenance Web (06d9b535f149ae45bfa511b709dd024b)

Applies to

Product(s): SuSE Linux Enterprise Server 8 for IBM zSeries

Package: k_deflt
Release: 20040112
Obsoletes: none

Indications

This update should be installed.

Contraindications

This kernel requires PTF UM30652 installed on systems using Guest LAN / Hipersockets with z/VM 4.3.

Description

This This update fixes a security vulnerability in the Linux kernel (CAN-2003-0985) and contains additional fixes and IBM codedrops. The changes in detail are:
Security fix
  • Add missing check in mremap (CAN-2003-0985)
IBM code drop from 2003-12-18
  • DASD driver sets improper default cache mode on ESS.
  • Massive workload combined with ESS flascopy leading to I/O hang.
IBM code drop from 2003-11-28
  • PCICCs fail to be detected under z90crypt.
  • z90crypt doesn't support dynamic device node generation.
  • Unable to reconnect when using z/VM 3.1 at remote peer.
  • fake_ll problems when IPv6 is not active in qeth.
  • multicast_router handling for IPv6 on OSA.
  • sclp: signal shutdown does not work.
  • zfcp: unwary memory allocation during error recovery.
IBM code drop from 2003-10-31
  • Crashes, triggered by IUCV and CTC when calling dst_link_failure().
  • DHCP does not work with HiperSockets guest LAN.
  • Fixed S390 Debug Feature usage.
  • Race Conditions in qeth when more than one osasnmpd is running.
  • VIPA and Proxy ARP problems on qeth.
  • Avoid hang during initialization on I/O errors.
  • Console: kernel compilation fails in drivers/s390/char/ctrlchar.c.
  • Crashes triggered by s390 network drivers calling dst_link_failure().
  • fake_ll source MAC problem.
  • Tape: Fix implementation of NOP mtio operation.
  • Tape: Initially boxed tapes might become invisible.
  • z90crypt incorrectly detects PCIXCC as PCICC.
  • zfcp: SCSI I/O stall due to missed local-link-up event.
  • zfcp: arbitrary (and bewildering) order of entries in /proc/scsi/zfcp/map.
  • zfcp: incomplete fix for dynamic SCSI adapter addition in scsi_mod.
  • zfcp: infinite error recovery escalation for certain port failure.
Further improvements
  • Corrected hangcheck driver
  • Fix a pointer arithmetic bug in the xattr code.
  • nfsd-fhalias (for HA-NFS): avoid console spew from invalid IP 0.
  • Fix bad ffs() return value, fixes fat and netfilter.
  • Fix NFS directio bug that causes data corruption when creating files larger than 4 GB.
  • Added missing epoll() syscalls.
IBM code drops
This updates contains the following IBM code drops:
  • 2003-10-31 kernel for the "June 2003 stream"
  • 2003-11-28 kernel for the "June 2003 stream"
  • 2003-12-18 kernel for the "June 2003 stream"

Solution

Please install the update provided at the location noted below.

Installation notes

This update is provided as an RPM package that can easily be installed onto a running system by using this command:
rpm -Uvh k_deflt.rpm zipl
Please make sure to run "zipl" to write the updated IPL code to the DASD or MDISK as the system won't boot at next IPL otherwise.
Now reboot the system with
shutdown -r now
to load the new kernel (replace "now" with the appropriate amount of time to allow local users to cleanly log out, for example "+5" for five minutes.)
