Red Hat Bugzilla – Bug 137530
linux/nfs_mount.h is missing #define for NFS_MOUNT_NOACL flag
Last modified: 2007-11-30 17:07:04 EST
User-Agent: Build Identifier: The RHEL3 kernel contains patches to add ACL support to NFS v3. This includes a new NFS mount option 'noacl'. The version of nfs_mount.h in the kjernel source contains the constant #define NFS_MOUNT_NOACL 0x0800 However, this is missing from the nfs_mount.h present in glibc-kernheaders. The am-utils automounter, uses the nfs_mount.h to determine what flags are supported for the mount syscall on NFS filesystems, thus needs this constant to be added. Reproducible: Always Steps to Reproduce: 1. Compile any program that wants the NFS_MOUNT_NOACL constant 2. 3. Actual Results: Comnpile fails / constant is not found Expected Results: Compiles succeeeds & constant is found
The upstream kernel doesn't define NFS_MOUNT_NOACL, so I don't believe we should be defining it in glibc-kernheaders either -- that should stick to the pure ABI and not include local hacks. Until/unless NFS_MOUNT_NOACL is supported in an upstream kernel (even a 2.6 kernel), please continue to define it in your own local header files. While it's a local hack in our kernel, it needs to remain a local hack in our userspace too, unforunately.
