Summary: 使用 NFSv4 时,客户端无法装载别名导出,并显示错误“作不允许”。通过 IP 或使用完整导出路径时装载成功。

Symptoms

使用 Kerberos 进行身份验证并拥有有效的通用安全服务 (GSS) 票证的网络文件系统 (NFS) 客户端尝试使用别名装载导出,但遇到故障:

# mount -t nfs4 fullyqualifieddomain:/aliases01  /mnt/test -vvvv
mount.nfs4: timeout set for Wed Apr 10 12:14:37 2024
mount.nfs4: trying text-based options 'vers=4.2,addr=x.x.x.x,clientaddr=x.x.x.x'
mount.nfs4: mount(2): Operation not permitted
mount.nfs4: trying text-based options 'vers=4,minorversion=1,addr=x.x.x.x,clientaddr=x.x.x.x'
mount.nfs4: mount(2): Operation not permitted
mount.nfs4: trying text-based options 'vers=4,addr=x.x.x.x,clientaddr=x.x.x.x'
mount.nfs4: mount(2): Operation not permitted
mount.nfs4: Operation not permitted

OneFS 响应时不会对 SECINFO 叫。数据包捕获中的示例:

Network File System
    [Program Version: 4]
    [V4 Procedure: COMPOUND (1)]
    GSS Data, Ops(2): PUTFH SECINFO
        Length: 36
        GSS Sequence Number: 3
        Status: NFS4_OK (0)
        Tag: <EMPTY>
            length: 0
            contents: <EMPTY>
        Operations (count: 2)
            Opcode: PUTFH (22)
                Status: NFS4_OK (0)
            Opcode: SECINFO (33)
                Status: NFS4_OK (0)
                Flavors Info
                    no values <<<<<<<<<<<<<<<<<<<<<<<<
        [Main Opcode: SECINFO (33)]

 

Cause

通常 SECINFO 为装载期间的有效文件句柄 (FH) 访问提供可选的风格值。

   The new SECINFO operation allows the client to determine, on a
   per filehandle basis, what security triple is to be used for server
   access.

但是,由于代码缺陷,客户端无法通过 ROOTFH。因此,OneFS 回复时不会显示任何风格,并且会话会被销毁。

Resolution

以下代码级别包含修复:

  • OneFS 9.4.0.19
  • OneFS 9.5.1.1
  • OneFS 9.7.1.1
  • OneFS 9.9+

在执行升级之前要使用的解决方法:

  1. 在装载时指定远程过程调用 (RPC) 身份验证方式,例如: sec=sys
  2. 使用完整装载路径与别名。
