Updated netcf packages that fix one bug are now available for Red Hat Enterprise Linux 6.
The netcf packages contain a library for modifying the network configuration of a system. Network configuration is expressed in a platform-independent XML format, which netcf translates into changes to the system's "native" network configuration files.
Previously, the netcf utility had been calling the nl_cache_mngt_provide() function in the libnl library, which was not thread-safe. Consequently, the libvirtd daemon could terminate unexpectedly. As nl_cache_mngt_provide() was not necessary for proper operation, it is no longer called by netcf, thus preventing this bug.
Users of netcf are advised to upgrade to these updated packages, which fix this bug.
