* afs: Support interacting with multiple user namespacesEric W. Biederman2013-02-131-2/+2
| | | | | | | | | | | | | | | | | | | | | | Modify struct afs_file_status to store owner as a kuid_t and group as a kgid_t. In xdr_decode_AFSFetchStatus as owner is now a kuid_t and group is now a kgid_t don't use the EXTRACT macro. Instead perform the work of the extract macro explicitly. Read the value with ntohl and convert it to the appropriate type with make_kuid or make_kgid. Test if the value is different from what is stored in status and update changed. Update the value in status. In xdr_encode_AFS_StoreStatus call from_kuid or from_kgid as we are computing the on the wire encoding. Initialize uids with GLOBAL_ROOT_UID instead of 0. Initialize gids with GLOBAL_ROOT_GID instead of 0. Cc: David Howells <dhowells@redhat.com> Acked-by: Serge Hallyn <serge.hallyn@canonical.com> Signed-off-by: Eric W. Biederman <ebiederm@xmission.com>
* afs: Remove unused structure afs_store_statusEric W. Biederman2013-02-121-7/+0
| | | | | | | | | | | | | While looking for kuid_t and kgid_t conversions I found this structure that has never been used since it was added to the kernel in 2007. The obvious for this structure to be used is in xdr_encode_AFS_StoreStatus and that function uses a small handful of local variables instead. So remove the unnecessary structure to prevent confusion.

* [AFS]: Add "directory write" support.David Howells2007-04-261-4/+22
| | | | | | | | | | | | | | | | Add support for the create, link, symlink, unlink, mkdir, rmdir and rename VFS operations to the in-kernel AFS filesystem. Also: (1) Fix dentry and inode revalidation. d_revalidate should only look at state of the dentry. Revalidation of the contents of an inode pointed to by a dentry is now separate. (2) Fix afs_lookup() to hash negative dentries as well as positive ones. Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* [AFS]: Add security support.David Howells2007-04-261-2/+25
| | | | | | | | | | Add security support to the AFS filesystem. Kerberos IV tickets are added as RxRPC keys are added to the session keyring with the klog program. open() and other VFS operations then find this ticket with request_key() and either use it immediately (eg: mkdir, unlink) or attach it to a file descriptor (open).
