2008-01-03NFS: Fix a possible Oops in fs/nfs/super.cTrond Myklebust
Sigh... commit 4584f520e1f773082ef44ff4f8969a5d992b16ec (NFS: Fix NFS mountpoint crossing...) had a slight flaw: server can be NULL if sget() returned an existing superblock. Fix the fix by dereferencing s->s_fs_info. Thanks to Coverity/Adrian Bunk and Frank Filz for spotting the bug. (See http://bugzilla.kernel.org/show_bug.cgi?id=9647) Also add in the same namespace Oops fix for NFSv4 in both the mountpoint crossing case, and the referral case.

2007-11-17kernel BUG at fs/nfs/namespace.c:108! - can be triggered by bad serverNeil Brown
Hi Trond, I have discovered that the BUG_ON in nfs_follow_mountpoint: BUG_ON(IS_ROOT(dentry)); can be triggered by a misbehaving server. What happens is the client does a lookup and discoveres that the named directory has a different fsid, so it initiates a mount. It then performs a GETATTR on the mounted directory and gets a different fsid again (due to a bug in the NFS server). This causes nfs_follow_mountpoint to be called on the newly mounted root, which triggers the BUG_ON. To duplicate this, have a directory which contains some mountpoints, and export that directory with the "crossmnt" flag using nfs-utils 1.1.1 (or 1.1.0 I think) The GETATTR on the root of the mounted filesystem will return the information for the top exportpoint, while a lookup will return the correct information. This difference causes the NFS client to BUG. I think the best way to fix this is to trap this possibility early, so just before completing the mount in the NFS client, check that it isn't going to use nfs_mountpoint_inode_operations. As long as i_op will never change once set (is that true?), this should be adequately safe. The following patch shows a possible approach, and it works for me. i.e. when the NFS server is misbehaving, I get ESTALE on those mountpoints, while when the NFS server is working correctly, I get correct behaviour on the client.

2007-10-09NFS: Add new 'mountaddr=' mount optionChuck Lever
I got the 'mounthost=' option wrong - it shouldn't look for an address value, but rather a hostname value. However, the in-kernel mount client and NFS client cannot resolve a hostname by themselves; they rely on user-land to pass in the resolved address. Create a new mount option that does take an address so that the mount program's address can be passed in. The mount hostname is now ignored by the kernel.

A minor thing, but useful when working with a server with multiple addrs. This looks like it might also be necessary if Miklos' effort to eliminate /etc/mtab ever comes to fruition. When displaying mount options in /proc/mounts, the kernel prints "addr=hostname". This info is redundant since we already have the hostname displayed as part of the "device" section of the mount.

2007-08-31NFS: Fix the mount regressionTrond Myklebust
This avoids the recent NFS mount regression (returning EBUSY when mounting the same filesystem twice with different parameters). The best I can do given the constraints appears to be to have the kernel first look for a superblock that matches both the fsid and the user-specified mount options, and then spawn off a new superblock if that search fails. Note that this is not the same as specifying nosharecache everywhere since nosharecache will never attempt to match an existing superblock.

2007-07-10NFS: Add the mount option "nosharecache"Trond Myklebust
Prior to David Howell's mount changes in 2.6.18, users who mounted different directories which happened to be from the same filesystem on the server would get different super blocks, and hence could choose different mount options. As long as there were no hard linked files that crossed from one subtree to another, this was quite safe. Post the changes, if the two directories are on the same filesystem (have the same 'fsid'), they will share the same super block, and hence the same mount options. Add a flag to allow users to elect not to share the NFS super block with another mount point, even if the fsids are the same. This will allow users to set different mount options for the two different super blocks, as was previously possible. It is still up to the user to ensure that there are no cache coherency issues when doing this, however the default behaviour will be to share super blocks whenever two paths result in the same fsid.

The current NFS client congestion logic is severly broken, it marks the backing device congested during each nfs_writepages() call but doesn't mirror this in nfs_writepage() which makes for deadlocks. Also it implements its own waitqueue. Replace this by a more regular congestion implementation that puts a cap on the number of active writeback pages and uses the bdi congestion waitqueue. Also always use an interruptible wait since it makes sense to be able to SIGKILL the process even for mounts without 'intr'.

2007-02-03NFSv4: Fix Oops in nfs4_create_referral_serverTrond Myklebust
The filehandle that is passed into nfs4_create_referral_server is not initialised. The expectation is that nfs4_create_referral_server will initialise it, and return it to the caller. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

2006-09-24[PATCH] Allow file systems to manually d_move() inside of ->rename()Mark Fasheh
Some file systems want to manually d_move() the dentries involved in a rename. We can do this by making use of the FS_ODD_RENAME flag if we just have nfs_rename() unconditionally do the d_move(). While there, we rename the flag to be more descriptive. OCFS2 uses this to protect that part of the rename operation with a cluster lock.
