Fedora 11 New Extended File Attributes Namespace

I am experimenting with XAM (eXtensible Access Method), which is a storage standard developed by SNIA (Storage Networking Industry Association and have developed a first prototype of a VIM (Vendor Interface Module) for the ext4 file system based on adding another namespace to the current extended file attributes support. Since other Linux developers might be interested in how to add an extended attributes namespace to a file system, I decided to publish this post as a guide.

Extended file attributes (EA) are extensions to the normal attributes which are associated with inodes in a file system. They are simply name:value pairs associated with files and directories and whose purpose is to provide additional functionality which is either defined by the operating system or a user application. An EA may be defined or undefined. If an EA is defined, its value may be empty or non-empty. Most of the initial work to support EAs in Linux was done by Andreas Gruenbacher in the 2001 to 2004 timeframe and is based on work done in the SGI XFS file system.

EAs are stored directly in inodes and on additional disk blocks if necessary. Currently all EAs associated with a file must fit in an inode and one additional block. Blocks that contain the identical set of EAs may be shared among several inodes. EAs in inodes and on blocks have a different header followed by multiple entry descriptors. Entry descriptors are sorted in disk blocks but are left unsorted in inodes.

EA names are zero-terminated strings and are always specified using a fully qualified namespace.attribute e.g. system.posix_acl_access or security.selinux. Namespaces are used to define different classes of EAs. Different EA classes are required because the permissions and capabilities required for manipulating EAs in one namespace may differ from one to another. Currently Linux supports EA namespaces for SELinux (security.), system (system.), trusted (trusted.) and user (user.).

Fedora 11 comes with EA support in the Linux kernel and hence it is the kernel which must be modified in order to add another EA namespace. In my case I wanted to add an EA namespace called snia in order to support XAM XSet metadata (see below).

Here is the patch file for the Fedora 11 2.6.29.4-167.fc11 kernel which implements the snia namespace. It should work for both 32-bit and 64-bit kernels but I have only tested it on a 64-bit kernel.

I am going to assume that if you are still reading this post you know how to build, package and install a Linux kernel in Fedora. If not, here is a good tutorial. The only caveat I would make is to ignore the comment that "most text editors know how to break the hardlink correctly to avoid problems." That is just plain wrong. You need to have separate standalone copies of any source file that you intend modifying in both the original and new kernel source trees - not a single hard linked copy - before you start making changes in the new kernel source tree.

Once you are running on the new kernel, you can set and get EAs in the snia namespace as shown in this simple example.

$ touch testfile
$ setfattr -n snia.test -v "hello world" testfile
$ getfattr -n snia.test testfile
# file: testfile
snia.test="hello world"

$

In the next example I set and get the metadata (called fields in XAM terminology) for a sample XAM XSet. A field has a name and a value, and the following standard attributes: type, length, binding and readonly. The attributes and values roughly correspond to the fields outputted as an XML document to a persisted XSet by the ReferenceXSetClient example included with the XAM SDK which is available on the SNIA website. For an introduction to the concepts of an XSystem and XSets a good starting place is Mark Carlson's blog.

Obviously this work is a proof-of-concept only. The actual XAM namespace is org.snia.xam.* and not the shortened version, i.e. snia.*, which I used in the proof-of-concept. I have not tested it sufficiently to discover boundary conditions or size limitations yet. I suspect that it might be better to store the snia namespace attributes in their own block(s) rather than sharing an inode or block with the other four namespaces and this is what I intend to prototype next.

If anybody else is interested in working with me in this space I would welcome their involvement.

Fedora 11 nVidia Twinview Support

Fedora 11 (Leonidas) ships with the nouveau nVidia graphics driver preloaded by default if a nVidia graphics card is detected at install time. Previous versions of Fedora used the older X.Org nv driver.

The nouveau project aims at producing Open Source 3D drivers for nVidia graphics cards. According to the nouveau project Wiki

2D-support is in fairly good shape with EXA acceleration, Xv and Randr12 (think of dual-head, rotations, etc.). Randr12 should work for all cards up to, and including, Geforce 9000 series, although some issues with Geforce 8/9 laptops may still exist, for such issues bug reports should be submitted. Randr12 is now the default. Any 3D functionality that might exist is still unsupported, do not ask for instructions to try it. Also, VT switching while X is running is considered lucky."

Well, I certainly quickly ran into the VT switching issue! It worked but not consistently.

Unfortunately the nouveau driver currently does not support nVidia TwinView functionality and I suspect that it will be a long time before it does if ever!

To use TwinView with Fedora 11, you have to load the correct nVidia drivers from rpmfusion.org. I described how to do this in detail in a previous post so I will not repeat that information here.

You also need to modify your grub.conf file to include the nopat kernel boot option as shown below.

title Fedora (2.6.29.4-167.fc11.x86_64)
       root (hd0,1)
       kernel /vmlinuz-2.6.29.4-167.fc11.x86_64 ro root=/dev/mapper/vg_ultra-lv_root rhgb quiet nopat
       initrd /initrd-2.6.29.4-167.fc11.x86_64.img

The nopat option is needed for this particular kernel (2.6.29.4) as it appears to still have broken PAT functionality.

For those readers who are unaware of what PAT is, here is a brief explanation. Traditionally page caching was controlled by a CPU feature called Memory Type Range Registers (MTRR). A CPU has a finite and limited set of MTRRs each of which control part of the physical address space. To overcome this limitation and provide a more flexible architecture, Intel and other x86 CPU vendors added a set of bits to page table entries to control how a CPU does page caching. These bits are called the Page Attribute Table (PAT). Incidentally, the 2.6.26 kernel was the first Linux kernel to support PATs.

Unless you rebuild your initial ramdisk (initrd), the nouveau driver will remain loaded in the kernel. I prefer not to have the nouveau driver loaded in my kernel if I am not using it so I added nouveau to the list of blacklisted drivers in /etc/modprobe.d/blacklist.conf and rebuild initrd.

After rebooting your system, if you use dmesg or lsmod, you will see that the nvidia driver was loaded instead of the nouveau driver.

You will also see that for some reason Plymouth no longer runs with a graphical splash screen if it previously did so. Plymouth is the replacement for the old RedHat Graphical Boot (RHGB). It was written by Ray Strode, Kristian Hogsberg and Peter Jones of Redhat and first shipped in Fedora 10.

Finally, you do not need to modify your xorg.conf file for Fedora 11. It should just work.
