* [PATCH] remove duplicate get_dentry functions in various placesChristoph Hellwig2005-06-236-27/+10
| | | | | | | | | | | | | | Various filesystem drivers have grown a get_dentry() function that's a duplicate of lookup_one_len, except that it doesn't take a maximum length argument and doesn't check for \0 or / in the passed in filename. Switch all these places to use lookup_one_len.

* [PATCH] fix for prune_icache()/forced final iput() racesAlexander Viro2005-06-231-6/+10
| | | | | | | | | | | | | | | | | | | | | | | | | Based on analysis and a patch from Russ Weight <rweight@us.ibm.com> There is a race condition that can occur if an inode is allocated and then released (using iput) during the ->fill_super functions. The race condition is between kswapd and mount. For most filesystems this can only happen in an error path when kswapd is running concurrently. For isofs, however, the error can occur in a more common code path (which is how the bug was found). The logic here is "we want final iput() to free inode *now* instead of letting it sit in cache if fs is going down or had not quite come up". The problem is with kswapd seeing such inodes in the middle of being killed and happily taking over. The clean solution would be to tell kswapd to leave those inodes alone and let our final iput deal with them. I.e. add a new flag (I_FORCED_FREEING), set it before write_inode_now() there and make prune_icache() leave those alone.

* [PATCH] NFS: Hide NFS server-generated readdir cookies from userlandOlivier Galibert2005-06-222-24/+92
| | | | | | | | | | | | NFSv3 currently returns the unsigned 64-bit cookie directly to userspace. The following patch causes the kernel to generate loff_t offsets for the benefit of userland. The current server-generated READDIR cookie is cached in the nfs_open_context instead of in filp->f_pos, so we still end up work correctly under directory insertions/deletion.

* [PATCH] NFS: Fix handling of the umask when an NFSv3 default acl is present.Andreas Gruenbacher2005-06-223-6/+64
| | | | | | | | | | | | | | | | | | | | | | | NFSv3 has no concept of a umask on the server side: The client applies the umask locally, and sends the effective permissions to the server. This behavior is wrong when files are created in a directory that has a default ACL. In this case, the umask is supposed to be ignored, and only the default ACL determines the file's effective permissions. Usually its the server's task to conditionally apply the umask. But since the server knows nothing about the umask, we have to do it on the client side. This patch tries to fetch the parent directory's default ACL before creating a new file, computes the appropriate create mode to send to the server, and finally sets the new file's access and default acl appropriately. Many thanks to Buck Huppmann <buchk@pobox.com> for sending the initial version of this patch, as well as for arguing why we need this change.
