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 |

FreeBSD Source:
This is the top level of the FreeBSD source directory.
FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
For copyright information, please see the file COPYRIGHT in this directory. Additional copyright information also exists for some sources in this tree - please see the specific source directories for more information.
The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree. See build(7), config(8), FreeBSD handbook on building userland, and Handbook for kernels for more information, including setting make(1) variables.
For information on the CPU architectures and platforms supported by FreeBSD, see the FreeBSD website's Platforms page.
