2015-02-02nfsd: implement pNFS operationsChristoph Hellwig16-5/+1324
Add support for the GETDEVICEINFO, LAYOUTGET, LAYOUTCOMMIT and LAYOUTRETURN NFSv4.1 operations, as well as backing code to manage outstanding layouts and devices. Layout management is very straight forward, with a nfs4_layout_stateid structure that extends nfs4_stid to manage layout stateids as the top-level structure. It is linked into the nfs4_file and nfs4_client structures like the other stateids, and contains a linked list of layouts that hang of the stateid. The actual layout operations are implemented in layout drivers that are not part of this commit, but will be added later. The worst part of this commit is the management of the pNFS device IDs, which suffers from a specification that is not sanely implementable due to the fact that the device-IDs are global and not bound to an export, and have a small enough size so that we can't store the fsid portion of a file handle, and must never be reused. As we still do need perform all export authentication and validation checks on a device ID passed to GETDEVICEINFO we are caught between a rock and a hard place. To work around this issue we add a new hash that maps from a 64-bit integer to a fsid so that we can look up the export to authenticate against it, a 32-bit integer as a generation that we can bump when changing the device, and a currently unused 32-bit integer that could be used in the future to handle more than a single device per export. Entries in this hash table are never deleted as we can't reuse the ids anyway, and would have a severe lifetime problem anyway as Linux export structures are temporary structures that can go away under load. Parts of the XDR data, structures and marshaling/unmarshaling code, as well as many concepts are derived from the old pNFS server implementation from Andy Adamson, Benny Halevy, Dean Hildebrand, Marc Eshel, Fred Isaman, Mike Sager, Ricardo Labiaga and many others.

2015-02-02fs: add FL_LAYOUT lease typeChristoph Hellwig2-4/+26
This (ab-)uses the file locking code to allow filesystems to recall outstanding pNFS layouts on a file. This new lease type is similar but not quite the same as FL_DELEG. A FL_LAYOUT lease can always be granted, an a per-filesystem lock (XFS iolock for the initial implementation) ensures not FL_LAYOUT leases granted when we would need to recall them. Also included are changes that allow multiple outstanding read leases of different types on the same file as long as they have a differnt owner. This wasn't a problem until now as nfsd never set FL_LEASE leases, and no one else used FL_DELEG leases, but given that nfsd will also issues FL_LAYOUT leases we will have to handle it now.

2015-01-16locks: add a new struct file_locking_context pointer to struct inodeJeff Layton3-1/+57
The current scheme of using the i_flock list is really difficult to manage. There is also a legitimate desire for a per-inode spinlock to manage these lists that isn't the i_lock. Start conversion to a new scheme to eventually replace the old i_flock list with a new "file_lock_context" object. We start by adding a new i_flctx to struct inode. For now, it lives in parallel with i_flock list, but will eventually replace it. The idea is to allocate a structure to sit in that pointer and act as a locus for all things file locking. We allocate a file_lock_context for an inode when the first lock is added to it, and it's only freed when the inode is freed. We use the i_lock to protect the assignment, but afterward it should mostly be accessed locklessly. Signed-off-by: Jeff Layton <jlayton@primarydata.com> Acked-by: Christoph Hellwig <hch@lst.de>

2015-01-15svcrdma: Handle additional inline contentChuck Lever1-0/+55
Most NFS RPCs place their large payload argument at the end of the RPC header (eg, NFSv3 WRITE). For NFSv3 WRITE and SYMLINK, RPC/RDMA sends the complete RPC header inline, and the payload argument in the read list. Data in the read list is the last part of the XDR stream. One important case is not like this, however. NFSv4 COMPOUND is a counted array of operations. A WRITE operation, with its large data payload, can appear in the middle of the compound's operations array. Thus NFSv4 WRITE compounds can have header content after the WRITE payload. The Linux client, for example, performs an NFSv4 WRITE like this: { PUTFH, WRITE, GETATTR } Though RFC 5667 is not precise about this, the proper way to convey this compound is to place the GETATTR inline, _after_ the front of the RPC header. The receiver inserts the read list payload into the XDR stream after the initial WRITE arguments, and before the GETATTR operation, thanks to the value of the read list "position" field. The Linux client currently sends the GETATTR at the end of the RPC/RDMA read list, which is incorrect. It will be corrected in the future. The Linux server currently rejects NFSv4 compounds with inline content after the read list. For the above NFSv4 WRITE compound, the NFS compound header indicates there are three operations, but the server finds nonsense when it looks in the XDR stream for the third operation, and the compound fails with OP_ILLEGAL. Move trailing inline content to the end of the XDR buffer's page list. This presents incoming NFSv4 WRITE compounds to NFSD in the same way the socket transport does.

2015-01-15svcrdma: Move read list XDR round-up logicChuck Lever1-28/+9
This is a pre-requisite for a subsequent patch. Read list XDR round-up needs to be done _before_ additional inline content is copied to the end of the XDR buffer's page list.

2015-01-15svcrdma: Support RDMA_NOMSG requestsChuck Lever2-3/+37
Currently the Linux server can not decode RDMA_NOMSG type requests. Operations whose length exceeds the fixed size of RDMA SEND buffers, like large NFSv4 CREATE(NF4LNK) operations, must be conveyed via RDMA_NOMSG. For an RDMA_MSG type request, the client sends the RPC/RDMA, RPC headers, and some or all of the NFS arguments via RDMA SEND. For an RDMA_NOMSG type request, the client sends just the RPC/RDMA header via RDMA SEND. The request's read list contains elements for the entire RPC message, including the RPC header. NFSD expects the RPC/RMDA header and RPC header to be contiguous in page zero of the XDR buffer. Add logic in the RDMA READ path to make the read list contents land where the server prefers, when the incoming message is a type RDMA_NOMSG message.

2015-01-15svcrdma: rc_position sanity checkingChuck Lever1-4/+12
An RPC/RDMA client may send large RPC arguments via a read list. This is a list of scatter/gather elements which convey RPC call arguments too large to fit in a small RDMA SEND. Each entry in the read list has a "position" field, whose value is the byte offset in the XDR stream where the data in that entry is to be inserted. Entries which share the same "position" value make up the same RPC argument. The receiver inserts entries with the same position field value in list order into the XDR stream. Currently the Linux NFS/RDMA server cannot handle receiving read chunks in more than one position, mostly because no current client sends read lists with elements in more than one position. As a sanity check, ensure that all received chunks have the same "rc_position."

2015-01-15svcrdma: Find rmsgp more reliablyChuck Lever1-14/+4
xdr_start() can return the wrong rmsgp address if an assumption about how the xdr_buf was constructed changes. When it gets it wrong, the client receives a reply that has gibberish in the RPC/RDMA header, preventing it from matching a waiting RPC request. Instead, make (and document) just one assumption: that the RDMA header for the client's RPC call is at the start of the first page in rq_pages.

2015-01-15svcrdma: Scrub BUG_ON() and WARN_ON() call sitesChuck Lever3-33/+49
Current convention is to avoid using BUG_ON() in places where an oops could cause complete system failure. Replace BUG_ON() call sites in svcrdma with an assertion error message and allow execution to continue safely. Some BUG_ON() calls are removed because they have never fired in production (that we are aware of). Some WARN_ON() calls are also replaced where a back trace is not helpful; e.g., in a workqueue task.
