> We intend to push this change to upstream Crash Utility too. As is the case with BZ #633449 (Z dumps on ELF), I'll make this dependent upon upstream acceptance as well. ------- Comment From rsisk.com 2010-10-04 11:14 EDT------- Code Upstream Status: Not Started IBM is signed up to test and provide feedback, setting OtherQA.

crash-5.0.0-23-s390_elf_and_diskdump_support.patch (backport)
------- Comment on attachment From mahesh.ibm.com 2010-11-15 21:27 EDT-------
Please find the attached backport-ed patch that enables s390x elf as well as diskdump support. This patch cleanly applies on crash version (crash-5.0.0-23) shipped through RHEL6.0.
The patch has been tested on RHEL6.0 and works fine.
Patch posted upstream by mahesh.ibm.com for review: https://www.redhat.com/archives/crash-utility/2010-November/msg00020.html > The patch has been tested on RHEL6.0 and works fine. Since there is no RHEL6 kernel support for this yet, and since the RHEL6 version of makedumpfile does not have this support, I need two sets of files to test/verify this patch-set with: (1) vmlinux / vmcore (ELF format) (2) vmlinux / vmcore (makedumpfile-generated) Obviously the vmlinux files can be the same, and for that matter it would be helpful if the "makedumpfile-generated" vmcore was created from the "ELF format" vmcore. mahesh.ibm.com does not have a Red Hat bugzilla account, so can you pass this request on to IBM? ------- Comment From mahesh.ibm.com 2010-11-17 11:03 EDT------- The s390 vmlinux and vmcore (in ELF format) is available at: http://kernel.beaverton.ibm.com/~msalgaon/crash/s390_vmcore/ The dumpfiles generated by makedumpfile are available at: http://kernel.beaverton.ibm.com/~msalgaon/crash/s390_vmcore/makedumpfile_generated/ Redhat may not have access to above urls. Can someone help me to make these files available to Redhat ? Thanks, -Mahesh. We do not have access to http://kernel.beaverton.ibm.com. Perhaps Steve Best can access them and transfer them inside Red Hat? Dave, just tried to access the files and I don't have access to them. once I get access to them I'll bring them over for you. -Steve Dave, I placed the files on one of my systems. standard beaker password root.eng.bos.redhat.com:/home/sbest/s390_vmcore/ ls -all total 1539048 drwxr-xr-x 2 root root 4096 Nov 18 13:24 . drwx------ 22 sbest sbest 4096 Nov 18 12:48 .. -rw-r--r-- 1 root root 22799287 Nov 18 13:20 dumpfile_c_d_31 -rw-r--r-- 1 root root 298670834 Nov 18 13:21 dumpfile_compressed -rw-r--r-- 1 root root 105503416 Nov 18 13:20 dumpfile_d_31 -rw-r--r-- 1 root root 1073744448 Nov 18 13:23 vmcore_elf -rw-r--r-- 1 root root 73651456 Nov 18 13:24 vmlinux-2.6.32-71.el6.s390x -Steve (In reply to comment #10) > Dave, > > I placed the files on one of my systems. standard beaker password > > > root.eng.bos.redhat.com:/home/sbest/s390_vmcore/ > > ls -all > total 1539048 > drwxr-xr-x 2 root root 4096 Nov 18 13:24 . > drwx------ 22 sbest sbest 4096 Nov 18 12:48 .. > -rw-r--r-- 1 root root 22799287 Nov 18 13:20 dumpfile_c_d_31 > -rw-r--r-- 1 root root 298670834 Nov 18 13:21 dumpfile_compressed > -rw-r--r-- 1 root root 105503416 Nov 18 13:20 dumpfile_d_31 > -rw-r--r-- 1 root root 1073744448 Nov 18 13:23 vmcore_elf > -rw-r--r-- 1 root root 73651456 Nov 18 13:24 vmlinux-2.6.32-71.el6.s390x > > -Steve Got 'em... Thanks for your help! ------- Comment From mahesh.ibm.com 2010-11-25 22:51 EDT------- Hi Dave, Will this backport patch go into RHEL6.1? (In reply to comment #12) > ------- Comment From mahesh.ibm.com 2010-11-25 22:51 EDT------- > Hi Dave, > > Will this backport patch go into RHEL6.1? That's the plan, yes... Patch applied in upstream version 5.1.0: http://people.redhat.com/anderson/crash.changelog.html - Implemented support for s390x compressed kdump dumpfiles created by the makedumpfile facility. (mahesh.ibm.com) This enhancement request was evaluated by the full Red Hat Enterprise Linux team for inclusion in a Red Hat Enterprise Linux minor release. As a result of this evaluation, Red Hat has tentatively approved inclusion of this feature in the next Red Hat Enterprise Linux Update minor release. While it is a goal to include this enhancement in the next minor release of Red Hat Enterprise Linux, the enhancement is not yet committed for inclusion in the next minor release pending the next phase of actual code integration and successful Red Hat and partner testing.
