Symptoms
已通過 Kerberos 驗證並擁有有效 Generic Security Service (GSS) 票證的網路檔案系統 (NFS) 用戶端嘗試使用別名掛接匯出,但遇到失敗:
# 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 在回應時不帶任何值來回應 SECINFO 呼。封包擷取中的範例:
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 在裝載期間為有效的檔句柄 (FH) 訪問提供可選的特定實例值。
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,由於代碼缺陷,客戶無法通過初步化合物獲得其真實靶標 ROOTFH。因此,OneFS 回覆沒有任何風格,工作階段也會遭到銷毀。
Resolution
以下代碼層級包含修補程式:
- OneFS 9.4.0.19
- OneFS 9.5.1.1
- OneFS 9.7.1.1
- OneFS 9.9+
在可執行升級之前使用的因應措施:
- 在裝載時指定遠端過程調用 (RPC) 身份驗證風格,例如:
sec=sys - 使用完整掛接路徑與別名。
