** Description changed: + [Impact] + + * Read from /dev/mem and scan DMI tables is dangerous, if /dev/mem is + not stable to read, it will cause ipmi-locate crash. + + [Test Case] + + * `sudo ipmi-locate` shall not crash + + [Regression Potential] + + * Reading from DMI tables is sysfs is more stable then reading from + /dev/mem and if DMI tables is not available ipmi-locate will use the old + way to search in /dev/mem. I believe its low regression risk + + ---- Similiar to bug 1499838 but not 100% same. ipmi-locate looks into /dev/mem for DMI tables and crash when DMI tables are not in accessible memory region. Kernel > v4.2 provides /sys/firmware/DMI/tables/DMI which is a much safer place to read.
