Red Hat Bugzilla – Bug 679581
"grubby --info=ALL" segfaults with dual boot parameters in grub.conf
Last modified: 2013-03-07 18:31:47 EST
Description of problem: When using grubby to parse boot parameters, it segfaults: [root@gss-rhel5u5-32 ~]# grep -v ^# /etc/grub.conf default=0 timeout=5 splashimage=(hd0,0)/grub/splash.xpm.gz serial --unit=0 --speed=115200 --word=8 --parity=no --stop=1 terminal --timeout=5 serial console title Red Hat Enterprise Linux Server (2.6.18-194.26.1.el5) root (hd0,0) kernel /vmlinuz-2.6.18-194.26.1.el5 ro root=/dev/vg0/root console=ttyS0,115200 rhgb quiet initrd /initrd-2.6.18-194.26.1.el5.img title Red Hat Enterprise Linux Server (2.6.18-194.el5) root (hd0,0) kernel /vmlinuz-2.6.18-194.el5 ro root=/dev/vg0/root console=ttyS0,115200 rhgb quiet initrd /initrd-2.6.18-194.el5.img title Other rootnoverify (hd0,0) chainloader +1 [root@gss-rhel5u5-32 ~]# grubby --info=ALL boot=/dev/vda index=0 kernel=/vmlinuz-2.6.18-194.26.1.el5 args="ro console=ttyS0,115200 rhgb quiet" root=/dev/vg0/root initrd=/boot/initrd-2.6.18-194.26.1.el5.img index=1 kernel=/vmlinuz-2.6.18-194.el5 args="ro console=ttyS0,115200 rhgb quiet" root=/dev/vg0/root initrd=/boot/initrd-2.6.18-194.el5.img index=2 Segmentation fault Version-Release number of selected component (if applicable): mkinitrd-5.1.19.6-68.el5 How reproducible: Setup dual boot system with Windows, then run "grubby --info=ALL" in RHEL Steps to Reproduce: 1. Verify GRUB parameters for Windows in grub.conf 2. Run "grubby --info=ALL" 3. Observe segfault once parameters for Windows boot are accessed Actual results: grubby segfaults with Windows boot definitions in grub.conf Expected results: grubby ignores Windows boot definitions in grub.conf, or returns "non linux entry", as it does in later versions (grubby-7.0.x).

Created attachment 481756 [details] commit 173351118ccb5b3595168a701fa7b4c1b9804106 This patch from the grubby repo will fix this.
