lib/oe/lsb: sanitise the distro identifier
The distribution identifier is often used to create filenames, so it needs to be safe to use as a filename. Whilst most distributions have e.g. Fedora or Debian as their name, it is possible that the name contains special characters. To ensure this doesn't cause a problem strip out any non-alphanumerics from the distribution name before returning it. [ YOCTO #9443 ] Signed-off-by: Ross Burton <> Signed-off-by: Richard Purdie <>
