* NFS: Send valid mode bits to the serverTrond Myklebust2006-01-06
| | | | | | | inode->i_mode contains a lot more than just the mode bits. Make sure that we mask away this extra stuff in SETATTR calls to the server. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFSv4: Ensure DELEGRETURN returns attributesTrond Myklebust2006-01-06
| | | | | | | | Upon return of a write delegation, the server will almost always bump the change attribute. Ensure that we pick up that change so that we don't invalidate our data cache unnecessarily. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFSv4: Convert LOCK rpc call into an asynchronous RPC callTrond Myklebust2006-01-06
| | | | | | In order to allow users to interrupt/cancel it. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

* NFSv4: Make open recovery track O_RDWR, O_RDONLY and O_WRONLY correctlyTrond Myklebust2006-01-06
| | | | | | | When recovering from a delegation recall or a network partition, we need to replay open(O_RDWR), open(O_RDONLY) and open(O_WRONLY) separately. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFSv4: Make open_confirm() asynchronous tooTrond Myklebust2006-01-06

* NFSv4: Convert open() into an asynchronous RPC callTrond Myklebust2006-01-06
| | | | | | | | | OPEN is a stateful operation, so we must ensure that it always completes. In order to allow users to interrupt the operation, we need to make the RPC call asynchronous, and then wait on completion (or cancel). Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

* NFSv4: Add post-op attributes to nfs4_proc_link()Trond Myklebust2005-10-27
| | | | | | | Optimise attribute revalidation when hardlinking. Add post-op attributes for the directory and the original inode. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFS: Add optional post-op getattr instruction to the NFSv4 file close.Trond Myklebust2005-10-27
| | | | | | | | "Optional" means that the close call will not fail if the getattr at the end of the compound fails. If it does succeed, try to refresh inode attributes. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFSv4: Add directory post-op attributes to the CREATE operations.Trond Myklebust2005-10-27
| | | | | | | | Since the directory attributes change every time we CREATE a file, we might as well pick up the new directory attributes in the same compound. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFS: Optimise inode attribute cache updatesTrond Myklebust2005-10-27
| | | | | | | Allow nfs_refresh_inode() also to update attributes on the inode if the RPC call was sent after the last call to nfs_update_inode(). Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFSv4: handle no acl attrJ. Bruce Fields2005-10-19
| | | | | | | | | Stop handing garbage to userspace in the case where a weird server clears the acl bit in the getattr return (despite the fact that they've already claimed acl support.)

* NFSv4: Make NFS clean up byte range locks asynchronouslyTrond Myklebust2005-10-18
| | | | | | Currently we fail to do so if the process was signalled. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFSv4: Fix a potential CLOSE raceTrond Myklebust2005-10-18
| | | | | | | | | | Once the state_owner and lock_owner semaphores get removed, it will be possible for other OPEN requests to reopen the same file if they have lower sequence ids than our CLOSE call. This patch ensures that we recheck the file state once nfs_wait_on_sequence() has completed waiting. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFSv4: Add functions to order RPC callsTrond Myklebust2005-10-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | NFSv4 file state-changing functions such as OPEN, CLOSE, LOCK,... are all labelled with "sequence identifiers" in order to prevent the server from reordering RPC requests, as this could cause its file state to become out of sync with the client. Currently the NFS client code enforces this ordering locally using semaphores to restrict access to structures until the RPC call is done. This, of course, only works with synchronous RPC calls, since the user process must first grab the semaphore. By dropping semaphores, and instead teaching the RPC engine to hold the RPC calls until they are ready to be sent, we can extend this process to work nicely with asynchronous RPC calls too. This patch adds a new list called "rpc_sequence" that defines the order of the RPC calls to be sent. We add one such list for each state_owner. When an RPC call is ready to be sent, it checks if it is top of the rpc_sequence list. If so, it proceeds. If not, it goes back to sleep, and loops until it hits top of the list. Once the RPC call has completed, it can then bump the sequence id counter, and remove itself from the rpc_sequence list, and then wake up the next sleeper. Note that the state_owner sequence ids and lock_owner sequence ids are all indexed to the same rpc_sequence list, so OPEN, LOCK,... requests are all ordered w.r.t. each other.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-16
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
