During recent testing related to the IETF NFSv4 Bakeathon, it was discovered that Kerberized NFSv4.1/4.2 mounts to pNFS servers (sec=krb5[ip],pnfs mount options) was broken. The FreeBSD client was using the "service principal" for the MDS to try and establish a rpcsec_gss credential for a DS, which is incorrect. (A "service principal" looks like "nfs@<fqdn-of-server>" and the <fqdn-of-server> for the DS is not the same as the MDS for most pNFS servers.) To fix this, the rpcsec_gss code needs to be able to do a reverse DNS lookup of the DS's IP address. A new kgssapi upcall to the gssd(8) daemon is added by this patch to do the reverse DNS along with a new rpcsec_gss function to generate the "service principal". A separate patch to the gssd(8) will be committed, so that this patch will fix the problem. Without the gssd(8) patch, the new upcall fails and current/incorrect behaviour remains. This bug only affects the rare case of a Kerberized (sec=krb5[ip],pnfs) mount using pNFS. This patch changes the internal KAPI between the kgssapi and nfscl modules, but since I did a version bump a few days ago, I will not do one this time. MFC after: 1 month |
