Stanislav Kinsbursky 2c9030eef9 SUNRPC: check RPC inode's pipe reference before dereferencing ... There are 2 tightly bound objects: pipe data (created for kernel needs, has reference to dentry, which depends on PipeFS mount/umount) and PipeFS dentry/inode pair (created on mount for user-space needs). They both independently may have or have not a valid reference to each other. This means, that we have to make sure, that pipe->dentry reference is valid on upcalls, and dentry->pipe reference is valid on downcalls. The latter check is absent - my fault. IOW, PipeFS dentry can be opened by some process (rpc.idmapd for example), but it's pipe data can belong to NFS mount, which was unmounted already and thus pipe data was destroyed. To fix this, pipe reference have to be set to NULL on rpc_unlink() and checked on PipeFS file operations instead of pipe->dentry check. Note: PipeFS "poll" file operation will be updated in next patch, because it's logic is more complicated.
