Can't we probe for the existence of openat64(), and then probe whether the bug exists, and if so, replace openat() for that platform? > > The bug was introduced on 2015-06-04 and fixed on 2015-08-10 in glibc. I guess it depends on whether we think these flawed versions are common in the wild, or whether vendors have patched the major distros and only self-built glibc remains vulnerable, on whether it is worth our effort. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
