Description

Updated kernel packages are now available as part of ongoing support and maintenance of CentOS Linux version 3. This is the first regular update.

The Linux kernel handles the basic functions of the operating system. This is the first regular kernel update for CentOS Linux version 3. It contains a new critical security fix, many other bug fixes, several device driver updates, and numerous performance and scalability enhancements. On AMD64 systems, a fix was made to the eflags checking in 32-bit ptrace emulation that could have allowed local users to elevate their privileges. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0001 to this issue. Other bug fixes were made in the following kernel areas: VM, NPTL, IPC, kernel timer, ext3, NFS, netdump, SCSI, ACPI, several device drivers, and machine-dependent support for the x86_64, ppc64, and s390 architectures. The VM subsystem was improved to better handle extreme loads and resource contention (such as might occur during heavy database application usage). This has resulted in a significantly reduced possibility of hangs, OOM kills, and low-mem exhaustion. Several NPTL fixes were made to resolve POSIX compliance issues concerning process IDs and thread IDs. A section in the Release Notes elaborates on a related issue with file record locking in multi-threaded applications. AMD64 kernels are now configured with NUMA support, S390 kernels now have CONFIG_BLK_STATS enabled, and DMA capability was restored in the IA64 agpgart driver. The following drivers have been upgraded to new versions: cmpci ------ 6.36 e100 ------- 2.3.30-k1 e1000 ------ 5.2.20-k1 ips -------- 6.10.52 megaraid --- v1.18k megaraid2 -- v2.00.9 All CentOS Linux 3 users are advised to upgrade their kernels to the packages associated with their machine architectures and configurations as listed in this erratum.
