2005-06-23[PATCH] Remove f_error field from struct fileChristoph Lameter1-5/+0
The following patch removes the f_error field and all checks of f_error. Trond said: f_error was introduced for NFS, and made sense when we were guaranteed always to have a file pointer around when write errors occurred. Since then, we have (for various reasons) had to introduce the nfs_open_context in order to track the file read/write state, and it made sense to move our f_error tracking there too.

2005-06-22[PATCH] NFS: Cleanup of caching code, and slight optimization of writes.Trond Myklebust2-18/+38
Unless we're doing O_APPEND writes, we really don't care about revalidating the file length. Just make sure that we catch any page cache invalidations. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
2005-06-22[PATCH] NFS: Fix the file size revalidationTrond Myklebust3-54/+21
Instead of looking at whether or not the file is open for writes before we accept to update the length using the server value, we should rather be looking at whether or not we are currently caching any writes. Failure to do so means in particular that we're not updating the file length correctly after obtaining a POSIX or BSD lock. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
2005-06-22[PATCH] NFSv4: Fix up races in nfs4_proc_setattr()Trond Myklebust1-36/+19

2005-06-22[PATCH] NFS: Hide NFS server-generated readdir cookies from userlandOlivier Galibert2-24/+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.

2005-06-22[PATCH] NFS: Cache the NFSv3 acls.Andreas Gruenbacher2-15/+86
Attach acls to inodes in the icache to avoid unnecessary GETACL RPC round-trips. As long as the client doesn't retrieve any acls itself, only the default acls of exiting directories and the default and access acls of new directories will end up in the cache, which preserves some memory compared to always caching the access and default acl of all files.

2005-06-22[PATCH] NFS: Fix handling of the umask when an NFSv3 default acl is present.Andreas Gruenbacher3-6/+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.

2005-06-22[PATCH] NFS: Add support for NFSv3 ACLsAndreas Gruenbacher8-6/+530
This adds acl support fo nfs clients via the NFSACL protocol extension, by implementing the getxattr, listxattr, setxattr, and removexattr iops for the system.posix_acl_access and system.posix_acl_default attributes. This patch implements a dumb version that uses no caching (and thus adds some overhead). (Another patch in this patchset adds caching as well.)

Currently we return -ENOMEM for every single failure to create a new auth. This is actually accurate for auth_null and auth_unix, but for auth_gss it's a bit confusing.

Add nfs4_acl field to the nfs_inode, and use it to cache acls. Only cache acls of size up to a page. Also prepare for up to a page of acl data even when the user doesn't pass in a buffer, as when they want to get the acl length to decide what size buffer to allocate. Signed-off-by: J.

2005-06-07[PATCH] NFS: Fix lookup intent handlingTrond Myklebust1-14/+35
We should never apply a lookup intent to anything other than the last path component in an open(), create() or access() call. Introduce the helper nfs_lookup_check_intent() which always returns zero if LOOKUP_CONTINUE or LOOKUP_PARENT are set, and returns the intent flags if we're on the last component of the lookup. By doing so, we fix a bug in open(O_EXCL), where we may end up optimizing away a real lookup of the parent directory.

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!
