## Description

In the Linux kernel, the following vulnerability has been resolved:  nfsd: fix refcount leak in nfsd_set_fh_dentry()  nfsd exports a "pseudo root filesystem" which is used by NFSv4 to find the various exported filesystems using LOOKUP requests from a known root filehandle.  NFSv3 uses the MOUNT protocol to find those exported filesystems and so is not given access to the pseudo root filesystem.  If a v3 (or v2) client uses a filehandle from that filesystem, nfsd_set_fh_dentry() will report an error, but still stores the export in "struct svc_fh" even though it also drops the reference (exp_put()). This means that when fh_put() is called an extra reference will be dropped which can lead to use-after-free and possible denial of service.  Normal NFS usage will not provide a pseudo-root filehandle to a v3 client.  This bug can only be triggered by the client synthesising an incorrect filehandle.  To fix this we move the assignments to the svc_fh later, after all possible error cases have been detected.
