An update that has one fix can now be installed.

Description:

This update for biosdevname fixes the following issues:

  • Read DMI info rom sysfs. (bsc#1174491)

A kernel with Secure Boot lockdown may prohibit reading the contents of /dev/mem, hence biosdevname fails. The recent kernel provides the DMI byte contents in /sys/firmware/dmi/tables/*.

  • Add buffer read helper using read explicitly.

mmap can't work well with a sysfs file and it's required to read the contents explicitly via read, even if USE_MMAP is enabled.
