allows specifying an RFC1001 target "called" name (netbios name of the server, which can now be pecified as mount option "servernetbiosname" but will eventually be passed in automatically on retry of host down error messages caused when server refuses to handle default server name and can not handle port 445).

2005-08-19Fix nasty ncpfs symlink handling bug.Linus Torvalds
This bug could cause oopses and page state corruption, because ncpfs used the generic page-cache symlink handlign functions. But those functions only work if the page cache is guaranteed to be "stable", ie a page that was installed when the symlink walk was started has to still be installed in the page cache at the end of the walk. We could have fixed ncpfs to not use the generic helper routines, but it is in many ways much cleaner to instead improve on the symlink walking helper routines so that they don't require that absolute stability. We do this by allowing "follow_link()" to return a error-pointer as a cookie, which is fed back to the cleanup "put_link()" routine. This also simplifies NFS symlink handling. Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-08-19[PATCH] jffs2: fix symlink error handlingAl Viro
The current calling conventions for ->follow_link() are already fairly complex. What we have is 1) you can return -error; then you must release nameidata yourself and ->put_link() will _not_ be called. 2) you can do nd_set_link(nd, ERR_PTR(-error)) and return 0 3) you can do nd_set_link(nd, path) and return 0 4) you can return 0 (after having moved nameidata yourself) jffs2 follow_link() is broken - it has an exit where it returns -EIO and leaks nameidata.

2005-08-18[PATCH] NFS: Introduce the use of inode->i_lock to protect fields in nfsiChuck Lever
Down the road we want to eliminate the use of the global kernel lock entirely from the NFS client. To do this, we need to protect the fields in the nfs_inode structure adequately. Start by serializing updates to the "cache_validity" field. Note this change addresses an SMP hang found by njw@osdl.org, where processes deadlock because nfs_end_data_update and nfs_revalidate_mapping update the "cache_validity" field without proper serialization. Test plan: Millions of fsx ops on SMP clients. Run Nick Wilson's breaknfs program on large SMP clients.

2005-08-18[PATCH] NFS: use atomic bitops to manipulate flags in nfsi->flagsChuck Lever
Introduce atomic bitops to manipulate the bits in the nfs_inode structure's "flags" field. Using bitops means we can use a generic wait_on_bit call instead of an ad hoc locking scheme in fs/nfs/inode.c, so we can remove the "nfs_i_wait" field from nfs_inode at the same time. The other new flags field will continue to use bitmask and logic AND and OR. This permits several flags to be set at the same time efficiently. The following patch adds a spin lock to protect these flags, and this spin lock will later cover other fields in the nfs_inode structure, amortizing the cost of using this type of serialization.

2005-08-17[PATCH] nfsd to unlock kernel before exitingSteven Rostedt
The nfsd holds the big kernel lock upon exit, when it really shouldn't. Not to mention that this breaks Ingo's RT patch. This is a trivial fix to release the lock. Ingo, this patch also works with your kernel, and stops the problem with nfsd. Note, there's a "goto out;" where "out:" is right above svc_exit_thread. The point of the goto also holds the kernel_lock, so I don't see any problem here in releasing it.

2005-08-16[PATCH] NFS: Ensure we always update inode->i_mode when doing O_EXCL createsTrond Myklebust
When the client performs an exclusive create and opens the file for writing, a Netapp filer will first create the file using the mode 01777. It does this since an NFSv3/v4 exclusive create cannot immediately set the mode bits. The 01777 mode then gets put into the inode->i_mode. After the file creation is successful, we then do a setattr to change the mode to the correct value (as per the NFS spec). The problem is that nfs_refresh_inode() no longer updates inode->i_mode, so the latter retains the 01777 mode. A bit later, the VFS notices this, and calls remove_suid(). This of course now resets the file mode to inode->i_mode & 0777. Hey presto, the file mode on the server is now magically changed to 0777. Duh...

2005-08-08[PATCH] fsnotify_name/inoderemoveJohn McCutchan
The patch below unhooks fsnotify from vfs_unlink & vfs_rmdir. It introduces two new fsnotify calls, that are hooked in at the dcache level. This not only more closely matches how the VFS layer works, it also avoids the problem with locking and inode lifetimes. The two functions are - fsnotify_nameremove -- called when a directory entry is going away. It notifies the PARENT of the deletion. This is called from d_delete(). - inoderemove -- called when the files inode itself is going away. It notifies the inode that is being deleted. This is called from dentry_iput().

2005-08-07[PATCH] namespace.c: fix bind mount from foreign namespaceMiklos Szeredi
I'm resending this patch, because I still believe it's the correct fix. Tested before/after applying the patch with a test application available from: http://www.inf.bme.hu/~mszeredi/nstest.c Bind mount from a foreign namespace results in an un-removable mount. The reason is that mnt->mnt_namespace is copied from the old mount in clone_mnt(). Because of this check_mnt() in sys_umount() will fail. The solution is to set mnt->mnt_namespace to current->namespace in clone_mnt(). clone_mnt() is either called from do_loopback() or copy_tree(). copy_tree() is called from do_loopback() or copy_namespace(). When called (directly or indirectly) from do_loopback(), always current->namspace is being modified: check_mnt(nd->mnt). So setting mnt->mnt_namespace to current->namspace is the right thing to do. When called from copy_namespace(), the setting of mnt_namespace is irrelevant, since mnt_namespace is reset later in that function for all copied mounts. Jamie said: This patch is correct. The old code was buggy for more fundamental and serious reason: it broke the invariant that a tree of vfsmnts all have the same value of mnt_namespace (and the same for the mnt_list list).
