An updated libtirpc package that fixes one bug is now available for Red Hat Enterprise Linux 6.
The libtirpc package contains SunLib's implementation of transport independent RPC (TI-RPC) documentation. This includes a library required by programs in the nfs-utils and rpcbind packages.
- Due to certain errors and missing code in libtirpc, user space NFS servers were not able to fully utilize the RPCSEC_GSS security protocol, which allows remote procedure call (RPC) protocols to access the Generic Security Services Application Programming Interface (GSS-API). With this update, the problems have been fixed in the libtirpc code. The RPCSEC_GSS protocol now can be used by NFS servers properly.
All users of libtirpc are advised to upgrade to this updated package, which fixes this bug.
