Updated crash-gcore-command packages that fix one bug are now available for Red Hat Enterprise Linux 6.
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.
- 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.
Users of crash-gcore-command are advised to upgrade to these updated packages, which fix this bug.
