RHBA-2013:1102 - crash-gcore-command bug fix update

Synopsis

crash-gcore-command bug fix update

Type/Severity

Bug Fix Advisory

Topic

Updated crash-gcore-command packages that fix one bug are now available for Red Hat Enterprise Linux 6.

Description

The crash-gcore-command packages contain an extension module for the crash utility that adds a "gcore" command which can create a core dump file of a user-space task that was running in a kernel dumpfile.

This update fixes the following bug:

  • VDSO and vsyscall pages are not contained in the generated process core dump, due to a backported madvise/MADV_DONTDUMP change in the Red Hat Enterprise Linux 6 kernel. With this update, the VDSO and vsyscall pages are contained in the generated core dump. (BZ#968897)

Users of crash-gcore-command are advised to upgrade to these updated packages, which fix this bug.

Solution

Before applying this update, make sure all previously-released errata relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/knowledge/articles/11258
