* orangefs: Avoid symlink upcall if target is too long.Martin Brandenburg2016-03-091-0/+3
| | | | | | | | | | | | Previously the client-core detected this condition by sheer luck! Since we used strncpy, no NUL byte would be included on the name. The client-core would call strlen, which would read past the end of its buffer, but return a number large enough that the client-core would return ENAMETOOLONG.

| | | | | | | | Thus d_revalidate is not obliged to check on as much, which will eventually lead the way to hammering the filesystem servers much less. Signed-off-by: Martin Brandenburg <martin@omnibond.com> Signed-off-by: Mike Marshall <hubcap@omnibond.com>

* OrangeFS: Change almost all instances of the string PVFS2 to OrangeFS.Yi Liu2015-12-031-67/+67
| | | | | | | | | | | | | | | | | | | | | | OrangeFS was formerly known as PVFS2 and retains the name in many places. I leave the device /dev/pvfs2-req since this affects userspace. I leave the filesystem type pvfs2 since this affects userspace. Further the OrangeFS sysint library reads fstab for an entry of type pvfs2 independently of kernel mounts. I leave extended attribute keys user.pvfs2 and system.pvfs2 as the sysint library understands these. I leave references to userspace binaries still named pvfs2. I leave the filenames.
