RHBA-2013:1720 - 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:

• Due to a backported madvise/MADV_DONTDUMP change in the Red Hat Enterprise

Linux 6 kernel, VDSO (Virtual Dynamically linked Shared Objects) and vsyscall
pages were missing in the generated process core dump. With this update, VDSO
and vsyscall pages are always contained in the generated process core dump.
(BZ#890232)

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