* nfsd: common grace period controlJ. Bruce Fields2008-10-03
| | | | | | | | | | | | | | | | | | | | | Rewrite grace period code to unify management of grace period across lockd and nfsd. The current code has lockd and nfsd cooperate to compute a grace period which is satisfactory to them both, and then individually enforce it. This creates a slight race condition, since the enforcement is not coordinated. It's also more complicated than necessary. Here instead we have lockd and nfsd each inform common code when they enter the grace period, and when they're ready to leave the grace period, and allow normal locking only after both of them are ready to leave. We also expect the locks_start_grace()/locks_end_grace() interface here to be simpler to build on for future cluster/high-availability work, which may require (for example) putting individual filesystems into grace, or enforcing grace periods across multiple cluster nodes.

* [NFSD] uninline nfsd4_op_name()Adrian Bunk2008-08-08
| | | | | | | | | | | | | | | | | | | | | | There doesn't seem to be a compelling reason why nfsd4_op_name() is marked as "inline": It's only used in a dprintk(), and as long as it has only one caller non-ancient gcc versions anyway inline it automatically.

* nfsd: Allow AIX client to read dir containing mountpointsFrank Filz2008-02-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch addresses a compatibility issue with a Linux NFS server and AIX NFS client. I have exported /export as fsid=0 with sec=krb5:krb5i I have mount --bind /home onto /export/home I have exported /export/home with sec=krb5i The AIX client mounts / -o sec=krb5:krb5i onto /mnt If I do an ls /mnt, the AIX client gets a permission error. Looking at the network traceIwe see a READDIR looking for attributes FATTR4_RDATTR_ERROR and FATTR4_MOUNTED_ON_FILEID. The response gives a NFS4ERR_WRONGSEC which the AIX client is not expecting. Since the AIX client is only asking for an attribute that is an attribute of the parent file system (pseudo root in my example), it seems reasonable that there should not be an error. In discussing this issue with Bruce Fields, I initially proposed ignoring the error in nfsd4_encode_dirent_fattr() if all that was being asked for was FATTR4_RDATTR_ERROR and FATTR4_MOUNTED_ON_FILEID, however, Bruce suggested that we avoid calling cross_mnt() if only these attributes are requested. The following patch implements bypassing cross_mnt() if only FATTR4_RDATTR_ERROR and FATTR4_MOUNTED_ON_FILEID are called. Since there is some complexity in the code in nfsd4_encode_fattr(), I didn't want to duplicate code (and introduce a maintenance nightmare), so I added a parameter to nfsd4_encode_fattr() that indicates whether it should ignore cross mounts and simply fill in the attribute using the passed in dentry as opposed to it's parent.

* knfsd: set the response bitmask for NFS4_CREATE_EXCLUSIVEJeff Layton2007-07-31
| | | | | | | | | | | | | | | | | | RFC 3530 says: If the server uses an attribute to store the exclusive create verifier, it will signify which attribute by setting the appropriate bit in the attribute mask that is returned in the results. Linux uses the atime and mtime to store the verifier, but sends a zeroed out bitmask back to the client. This patch makes sure that we set the correct bits in the bitmask in this situation.

* [PATCH] knfsd: nfsd4: fix owner-override on openJ. Bruce Fields2006-10-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a client creates a file using an open which sets the mode to 000, or if a chmod changes permissions after a file is opened, then situations may arise where an NFS client knows that some IO is permitted (because a process holds the file open), but the NFS server does not (because it doesn't know about the open, and only sees that the IO conflicts with the current mode of the file). As a hack to solve this problem, NFS servers normally allow the owner to override permissions on IO. The client can still enforce correct permissions-checking on open by performing an explicit access check. In NFSv4 the client can rely on the explicit on-the-wire open instead of an access check. Therefore we should not be allowing the owner to override permissions on an over-the-wire open! However, we should still allow the owner to override permissions in the case where the client is claiming an open that it already made either before a reboot, or while it was holding a delegation.

As we plan to increase RPCSVC_MAXPAGES from 8 upto 256, we can no longer allocate an array of this size on the stack. So we allocate it in 'struct svc_rqst'. However svc_rqst contains (indirectly) an array of the same type and size (actually several, but they are in a union). So rather than waste space, we move those arrays out of the separately allocated union and into svc_rqst to share with the kvec moved out of svc_tcp_recvfrom (various arrays are used at different times, so there is no conflict).

Unfortunately in that patch I stupidly moved the grace-period check back too far, so now an open for create can succesfully create the file while still returning ERR_GRACE.

* [PATCH] nfsd4: block metadata ops during grace periodNeilBrown2005-06-24
| | | | | | | | | | | | | | | | We currently return err_grace if a user attempts a non-reclaim open during the grace period. But we also need to prevent renames and removes, at least, to ensure clients have the chance to recover state on files before they are moved or deleted. Of course, local users could also do renames and removes during the lease period, and there's not much we can do about that. This at least will help with remote users. Signed-off-by: J.

* [PATCH] nfsd4: support CLAIM_DELEGATE_CURNeilBrown2005-06-24
| | | | | | | | | | | | | | Add OPEN claim type NFS4_OPEN_CLAIM_DELEGATE_CUR to nfsd4_open(). A delegation stateid and a name are provided. OPEN with O_CREAT is not legal with this claim type; otherwise, use the NFS4_OPEN_CLAIM_NULL code path to lookup the filename to be opened.

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!
