Instead of calling layoutreturn directly, call pnfs_error_mark_layout_for_return to mark layouts for return and let generic code return layout when layout segments are freed.

It marks all matching layout segments as NFS_LSEG_LAYOUTRETURN, which is an indicator for pnfs_put_lseg() to send layoutreturn, and also prevents pnfs_update_layout() from using the returning segments. Once it is set, it never gets cleared. It also sets proper io failure bit so that pnfs path can be retried after PNFS_LAYOUTGET_RETRY_TIMEOUT second.

Per RFC 5661 Errata 3208: | A client MAY always forget its layout state and associated | layout stateid at any time (See also section 12.5.5.1). | In such case, the client MUST use a non-layout stateid for the next | LAYOUTGET operation. This will signal the server that the client has | no more layouts on the file and its respective layout state can be | released before issuing a new layout in response to LAYOUTGET. In order to make such a signal unique to server, client needs to serialize all layoutgets using non-layout stateid. We implement this by serializing layoutgets when client has no layout segments at hand. Signed-off-by: NPeng Tao <tao.peng@primarydata.com> Signed-off-by: NTom Haynes <Thomas.Haynes@primarydata.com>

由 Trond Myklebust 提交于
While we normally expect the NFSv4 client to always send the same client owner to all servers, there are a couple of situations where that is not the case: 1) In NFSv4.0, switching between use of '-omigration' and not will cause the kernel to switch between using the non-uniform and uniform client strings. 2) In NFSv4.1, or NFSv4.0 when using uniform client strings, if the uniquifier string is suddenly changed. This patch will catch those situations by checking the client owner id in the trunking detection code, and will do the right thing if it notices that the strings differ.

-
由 Trond Myklebust 提交于
Currently, our trunking code will check for session trunking, but will fail to detect client id trunking. This is a problem, because it means that the client will fail to recognise that the two connections represent shared state, even if they do not permit a shared session. By removing the check for the server minor id, and only checking the major id, we will end up doing the right thing in both cases: we close down the new nfs_client and fall back to using the existing one.

Use the correct calculation of the maximum size of a clientaddr4 when encoding and decoding SETCLIENTID operations. clientaddr4 is defined in section 2.2.10 of RFC3530bis-31. The usage in encode_setclientid_maxsz is missing the 4-byte length in both strings, but is otherwise correct. decode_setclientid_maxsz simply asks for a page of receive buffer space, which is unnecessarily large (more than 4KB). Note that a SETCLIENTID reply is either clientid+verifier, or clientaddr4, depending on the returned NFS status. It doesn't hurt to allocate enough space for both.
