Important things (AKA: ''the cool stuff'')

GFS2

GFS2 is a clustering filesystem developed mainly by Red Hat (after [http://www.theregister.co.uk/2003/12/18/red_hat_sweetens_q3/ purchasing Sistina] and opening the source code). It's not the first: OCFS2, another clustering filesystem developed by Oracle, was already merged in [http://kernelnewbies.org/Linux_2_6_16 Linux 2.6.16]. Clustering filesystems allow to share a filesystem between several machines with no compromises. GFS includes his own DLM (distributed locking manager) and a userspace API interface for that DLM.

Like OCFS2 and like any other filesystem that wants to be merged in the linux kernel, GFS2 developers asked for submission long time ago. They were asked to fix things (even considering that GFS2 had already been developed at Sistina and it was already a stable final product), they submitted it again, they were asked to fix more things, and so on, for a long period of time. Their developers have fixed every thing they were asked to fix. Because of their hard work, GFS2 is now ready to be merged, nobody oposes to it, and everyone is happy, there're no flames or accusations anywhere. Amazing, isn't? In fact, 3 new filesystems are being merged in 2.6.19.

ECRYPTFS

Coming from IBM, ecryptfs aims to bring "enterprise level" file encryption to the masses.

"Oh no, another filesystem!". No, Ecryptfs is not a traditional filesystem: it doesn't implements his own disk format. From [http://lwn.net/Articles/156921/ this LWN article]:

The eCryptfs developers took the stacking approach, meaning that, rather than implement its own platter-level format, eCryptfs sits on top of another filesystem. It is, essentially, a sort of translation layer which makes encrypted file capabilities available. The system administrator can thus create encrypted filesystems on top of whatever filesystem is in use locally, or even over a network-mounted filesystem. [...] Rather than encrypt the filesystem as a whole, eCryptfs deals with each file individually

(Reading the rest of the [http://lwn.net/Articles/156921 LWN article] is recommended. There's also a [http://www.linuxsymposium.org/2005/linuxsymposium_procv1.pdf Ecryptfs paper from the 2005 Ottawa Symposium] - page 209 and onwards)

Is it better to encrypt the whole disk using cryptoloop/dmcrypt, or use ecryptfs? You decide. Ecryptfs avoids the overhead of a fully encrypted filesystem by only encrypting the files you really want to encrypt, and it also allows to encrypt different files in different ways. Ecryptfs tries to make file encryption available in a easy way for the masses. It "aims to combine the flexibility of GnuPG encryption with the transparency of a kernel service" [...] "Think of eCryptfs as a sort of 'gnupgfs'". If you're interested, you will find the userspace tools and more information available in the [http://ecryptfs.sourceforge.net/ ecryptfs sourceforge site]. You can also read the [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob;f=Documentation/ecryptfs.txt Ecryptfs documentation] and the [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=237fead619984cc48818fe12ee0ceada3f55b012 Ecryptfs code] (232 KB).

Libata PATA (Parallel ATA) merge

By "Parallel ATA" we mean all the ATA/IDE controllers and drives that we have been using for years before SATA. Almost from the start, one of the objectives of some kernel hackers was to [http://marc.theaimsgroup.com/?l=linux-kernel&m=115514409104283&w=2 replace the IDE drivers available in drivers/ide] (everything under the "Device drivers -> ATA/ATAPI/MFM/RLL support" configuration menu) with a reimplementation on top of libata (i.e.: the "SATA layer"). Drivers/ide suffers from many ugly and obscure problems, and re-implementing it on top of libata has been much easier than fixing the unfixable drivers/ide mess - most of the porting work has been done by Alan Cox (a consequence of this PATA merge is that libata and all its SATA drivers have also been moved from drivers/scsi (available in the "Device drivers -> SCSI device support -> SCSI low-level drivers" submenu) to drivers/ata (now "Device drivers -> Serial ATA (prod) and Parallel ATA (experimental) drivers"), and all the CONFIG_SCSI_FOOBAR options for the individual SATA drivers have been changed to CONFIG_FOOBAR, so this means you may need to reconfigure your SATA configuration options)

This means 2.6.19 may have two drivers for your PATA-base device: The old IDE driver under "Device drivers -> ATA/ATAPI/MFM/RLL support" and an alternative driver under "Device drivers -> Serial ATA (prod) and Parallel ATA (experimental) drivers" (along with the rest of the SATA drivers)

What one must you choose? Well, the safe option is using the old driver: The old drivers will continue working just as they did before. There'll be no changes if you continue using the old drivers.

What do the new libata-base PATA drivers offer to you?

First of all, because they're libata-based and libata is a well engineered and sane infrastructure, the drivers have much better quality, they're cleaner, they've much better error handling (much better behaviour when one of your drives dies suddenly or finds broken sectors), and they don't have some of the known design issues that the old drivers have (this is why people did all the work to move away from drivers/ide, they didn't do it just for fun)
Because they're newer, there are more bugs. For this release, they're "experimental". If you want to be safe, use the old drivers.
Really. There is a risk that the new drivers won't work for you, or may harm your data (unlikely, but not impossible). If you want to be safe, use the old drivers.
They support some chipsets not supported by drivers/ide. The cleaner design of libata allows for easier driver development and maintenance. In some cases it supports features that the old driver doesn't, for the same reasons.
Some IDE controllers are not supported or they aren't fully supported. Some of them because not all the IDE drivers have been ported to libata, but others because they're old and undocumented or because the libata PATA layer still doesn't support some of their features. There's no support for certain old serialized devices, for prehistoric CMD640 controllers or for host-protected-area yet.
Drives appear as /dev/sda, /dev/sr0, the old devices names won't work. You will need to change your boot parameters and your /etc/fstab parameters in order to get a working system with the new drivers. Again, this only happens if you use the new drivers, the old drivers continue working as they did before.

Eventually, the new libata-based PATA drivers will get more stable, so the old drivers in drivers/ide may get deleted as the new drivers fulfill all needs of the IDE users and becomes feature-complete. But this certainly won't happen anytime soon. No old drivers will be deleted if there's not a working libata-based replacement. You can read the latest [http://zeniv.linux.org.uk/~alan/IDE/STATUS.txt status report] written by Alan Cox. It'd certainly be useful if you could give it a try and report back how well it works to linux-kernel@vger.kernel.org or bugzilla.kernel.org - even if it works fine, it'll be useful to know what systems do work (be sure to include the necessary information mentioned in the previous status report).

Removal of selected OSS drivers

Since 2.6 was released, ALSA has been the "official" sound subsystem. OSS drivers were kept for compatibility - ALSA also implements a OSS compatibility layer. However, there's a big number of ALSA drivers and OSS drivers targetting exactly the same hardware. Usually, the OSS ones are undermaintained (or no maintained at all). And ALSA already implements OSS compatibility. So....

...it's possible to remove old OSS drivers, as long as there's a equivalent ALSA driver, and as long as that driver has no regressions that don't allow users to migrate (drivers with no ALSA equivalent or with know regressions have NOT been deleted). In 2.6.19, those OSS drivers are being removed. If when migrating users find something wrong in the ALSA drivers, they should report it in the [https://bugtrack.alsa-project.org ALSA bug tracking system] and work with developers to fix them. Yes, we know there're users that feel just fine with the OSS drivers, but it doesn't helps to the kernel to keep those old drivers around. By forcing people to migrate to ALSA drivers, the ALSA drivers will be improved and fixed. Overall, the linux sound subsystem will only get better. Many thanks to all the hackers that coded them.

A total of 1.79 MB of OSS drivers will be removed. To see a list of source files being removed, see [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=d56b9b9c464a10ab1ee51a4c6190a2b57b8ef7a6 the commit link]. Hardware that is forced to use ALSA drivers include:

AVR32 Architecture

2.6.19 adds support for the Atmel AVR32 architecture, implemented and supported by Atmel Corporation.

AVR32 is a new high-performance 32-bit RISC microprocessor core, designed for cost-sensitive embedded applications, with particular emphasis on low power consumption and high code density. The AVR32 architecture description, including the instruction set, can be found in the [http://www.atmel.com/dyn/resources/prod_documents/doc32000.pdf AVR32 Architecture Manual]. The Atmel AT32AP7000 is the first CPU implementing the AVR32 architecture; it features a 7-stage pipeline, 16KB instruction and data caches and a full Memory Management Unit and a large set of integrated peripherals ([http://www.atmel.com/dyn/resources/prod_documents/doc32003.pdf full data sheet]); while the CPU core implementation including caches and MMU is documented by the [http://www.atmel.com/dyn/resources/prod_documents/doc32001.pdf AVR32 AP Technical Reference]. Information about the AT32STK1000 development board can be found [http://www.atmel.com/dyn/products/tools_card.asp?tool_id=3918 here], including a BSP CD image, development tools (binaries and source/patches) and a root filesystem image suitable for booting from SD card. Alternatively, there's a preliminary "getting started" guide available at http://avr32linux.org/twiki/bin/view/Main/GettingStarted which provides links to the sources and patches you will need in order to set up a cross-compiling environment for avr32-linux

Parallel device probing

(Disabled by default). Most of the boot time speeds up are in userspace, but some minor improvements can be done in the kernel. Until now Linux (and most, if not all the other OS - if there's another OS doing this it'd be interesting to hear about it) when booting take a secuential approach: One device is probed, initializated, etc, after other, then the next subsystem is intializated, a driver is loaded, it detects the device, another driver is loaded, etc etc.

This can cause some minor delays. For example, in the good old days when linux users were real men and didn't use bootsplash and didn't silented their dmesg outputs, you could see a small delay in the IDE driver when probing for disks. This is not a misfeature in the IDE driver, this was a requeriment of IDE. SCSI is even worse - probing for disk can take as much as 30 seconds, 1 minute, or even more! Other small delays can happen in other devices - for example, some devices may require a firmware upload or they may just need some seconds to power up. In embedded devices, this kind of delays can make bootup slower.

This situation is suboptimal. In 2.6.19, the code has changed to allow parallel device probing. The drivers continue working as always, but the kernel won't wait for the driver to finish its work. Instead, the kernel will continue initializating other drivers and subsystems, and will wait for them to finish when it has to run init. In multiprocessor systems, drivers may be initializated in another CPU while the rest of the kernels runs in the the main one.

However this feature is experimental, and for now it's only supported by the PCI subsystem. Some PCI drivers can not properly handle running in this way, and others might decide to blow up power supplies with a huge load all at once, so use this option at your own risk.

=== Sleepable RCU (Read Copy Update)=== [http://lwn.net/Articles/202847/ (LWN article by Paul McKenney, who implemented it)]

Like in spinlocks, RCU read-side critical sections were prohibited. However, many people had frequently requested a "sleepable RCU". Furthermore, the realtime capabilities beind developed in the -rt patch required that those critical sections were preemptible. So a RCU variant permitting read-side blocking has been developed, and a SRCU-base notifier chain has also been merged [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=621934ee7ed5b073c7fd638b347e632c53572761 (commit)], [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=eabc069401bcf45bcc3f19e643017bf761780aa8 (commit)]

Add infrastructure to track "maximum allowable latency" for power saving policies. The reason for adding this infrastructure is that power management in the idle loop needs to make a tradeoff between latency and power savings (deeper power save modes have a longer latency to running code again). The code that today makes this tradeoff just does a rather simple algorithm; however this is not good enough: There are devices and use cases where a lower latency is required than that the higher power saving states provide. An example would be audio playback, but another example is the ipw2100 wireless driver that right now has a very direct and ugly acpi hook to disable some higher power states randomly when it gets certain types of error. The proposed solution is to have an interface where drivers can 1) announce the maximum latency (in microseconds) that they can deal with 2) modify this latency 3) give up their constraint [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=5c87579e65ee4f419b2369407f82326d38b5d2d8 (commit)], [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=9442e691e4aec85eba43ac60a3e77c77fd2e73a4 (commit)]

Non lazy "sleazy" fpu implementation. Right now the kernel on x86-64 has a 100% lazy fpu behavior: after *every* context switch a trap is taken for the first FPU use to restore the FPU context lazily. This is great for applications that have very sporadic or no FPU use (since then you avoid doing the expensive save/restore all the time). However for very frequent FPU users... you take an extra trap every context switch. So 2.6.19 adds a simple heuristic to this code: After 5 consecutive context switches of FPU use, the lazy behavior is disabled and the context gets restored every context switch. If the app indeed uses the FPU, the trap is avoided. (the chance of the 6th time slice using FPU after the previous 5 having done so are quite high obviously). After 256 switches, this is reset and lazy behavior is returned (until there are 5 consecutive ones again) [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=e07e23e1fd3000289fc7ccc6c71879070d3b19e0 (commit)]

* [MLSXFRM]: Granular IPSec associations for use in MLS environments: The current approach to labeling Security Associations for SELinux

purposes uses a one-to-one mapping between xfrm policy rules and security associations. This doesn't address the needs of real world MLS (Multi-level System,
traditional Bell-LaPadula) environments where a single xfrm policy rule (pertaining to a range, classified to secret for example) might need to map to multiple Security Associations (one each for classified, secret, top secret and all the compartments applicable to these security levels). This patch set addresses the above problem by allowing for the mapping of a single xfrm policy rule to multiple security associations, with each association used in the security context it is defined for. It also includes the security context to be used in IKE negotiation in the acquire messages sent to the IKE daemon so that a unique SA can be negotiated for each unique security context. A couple of bug fixes are also included; checks to make sure the SAs used by a packet match policy (security context-wise) on the inbound and also that the bundle used for the outbound matches the security context of the flow. This patch set also makes the use of the SELinux sid in flow cache lookups seemless by including the sid in the flow key itself. Also, open requests as well as connection-oriented child sockets are labeled automatically to be at the same level as the peer to allow for use of appropriately labeled IPSec associations.

* [PATCH] SELinux: support mls categories for context mounts: Allows commas to be embedded into context mount options (i.e. "-o

context=some_selinux_context_t"), to better support multiple categories, which are separated by commas and confuse mount. For example, with the current code:
- mount -t iso9660 /dev/cdrom /media/cdrom -o \ ro,context=system_u:object_r:iso9660_t:s0:c1,c3,c4,exec
The context option that will be interpreted by SELinux is context=system_u:object_r:iso9660_t:s0:c1 instead of context=system_u:object_r:iso9660_t:s0:c1,c3,c4 The options that will be passed on to the file system will be ro,c3,c4,exec. The proposed solution is to allow/require the SELinux context option specified to mount to use quotes when the context contains a comma. This patch modifies the option parsing in parse_opts(), contained in mount.c, to take options after finding a comma only if it hasn't seen a quote or if the quotes are matched. It also introduces a new function that will strip the quotes from the context option prior to translation. The quotes are replaced after the translation is completed to insure that in the event the raw context contains commas the kernel will be able to interpret the correct context.

* [NetLabel]: SELinux support: Add NetLabel support to the SELinux LSM and modify the

socket_post_create() LSM hook to return an error code. The most
significant part of this patch is the addition of NetLabel hooks into the following SELinux LSM hooks:
- selinux_file_permission()
- selinux_socket_sendmsg()
- selinux_socket_post_create()
- selinux_socket_sock_rcv_skb()
- selinux_socket_getpeersec_stream()
- selinux_socket_getpeersec_dgram()
- selinux_sock_graft()
- selinux_inet_conn_request()
The basic reasoning behind this patch is that outgoing packets are
"NetLabel'd" by labeling their socket and the NetLabel security attributes are checked via the additional hook in selinux_socket_sock_rcv_skb(). NetLabel itself is only a labeling mechanism, similar to filesystem extended attributes, it is up to the SELinux enforcement mechanism to perform the actual access checks. In addition to the changes outlined above this patch also includes some changes to the extended bitmap (ebitmap) and multi-level security (mls) code to import and export SELinux TE/MLS attributes into and out
of NetLabel.

network stack. CIPSO has become a de-facto standard for trusted/labeled networking amongst existing Trusted Operating Systems such as Trusted Solaris, HP-UX CMW, etc. This implementation is
designed to be used with the NetLabel subsystem to provide explicit packet labeling to LSM developers.
The CIPSO/IPv4 packet labeling works by the LSM calling a NetLabel API function which attaches a CIPSO label (IPv4 option) to a given socket; this in turn attaches the CIPSO label to every packet leaving the socket without any extra processing on the outbound side. On the inbound side the individual packet's sk_buff is examined through a call to a NetLabel API function to determine if a CIPSO/IPv4 label is present and if so the security attributes of the CIPSO label are returned to the caller of the NetLabel API function.

* [XFRM] POLICY: sub policy support.: Sub policy is introduced. Main and sub policy are applied the same flow.

(Policy that current kernel uses is named as main.) It is required another transformation policy management to keep IPsec and Mobile IPv6 lives separate. Policy which lives shorter time in kernel should be a sub i.e. normally main is for IPsec and sub is for Mobile IPv6. (Such usage as two IPsec policies on different database can be used, too.) Limitation or TODOs:
- - Sub policy is not supported for per socket one (it is always inserted as main). - Current kernel makes cached outbound with flowi to skip searching database.
  - However this patch makes it disabled only when "two policies are used and the first matched one is bypass case" because neither flowi nor bundle information knows about transformation template size.

CPUFREQ

* add powersave_bias tunable. ondemand selects the minimum frequency that can retire a workload with negligible idle time -- ideally resulting in the highest performance/power efficiency with negligible performance impact. But on some systems and some workloads, this algorithm is more performance biased than necessary, and de-tuning it a bit to allow some performance impact can save measurable power. This patch adds a "powersave_bias" tunable to ondemand to allow it to reduce its target frequency by a specified percent. By default, the powersave_bias is 0 and has no effect. powersave_bias is in units of 0.1%, so it has an effective range of 1 through 1000, resulting in 0.1% to 100% impact. In practice, users will not be able to detect a difference between 0.1% increments, but 1.0% increments turned out to be too large. Also, the max value of 1000 (100%) would simply peg the system in its deepest power saving P-state, unless the processor really has a hardware P-state at 0Hz:-)

+=== Parallel device probing ===
(Disabled by default). Most of the boot time speeds up are in userspace, but some minor improvements can be done in the kernel. Until now Linux (and most, if not all the other OS - if there's another OS doing this it'd be interesting to hear about it) when booting take a secuential approach: One device is probed, initializated, etc, after other, then the next subsystem is intializated, a driver is loaded, it detects the device, another driver is loaded, etc etc.

This can cause some minor delays. For example, in the good old days when linux users were real men and didn't use bootsplash and didn't silented their dmesg outputs, you could see a small delay in the IDE driver when probing for disks. This is not a misfeature in the IDE driver, this was a requeriment of IDE. SCSI is even worse - probing for disk can take as much as 30 seconds, 1 minute, or even more! Other small delays can happen in other devices - for example, some devices may require a firmware upload or they may just need some seconds to power up. In embedded devices, this kind of delays can make bootup slower.

This situation is suboptimal. In 2.6.19, the code has changed to allow parallel device probing. The drivers continue working as always, but the kernel won't wait for the driver to finish its work. Instead, the kernel will continue initializating other drivers and subsystems, and will wait for them to finish when it has to run init. In multiprocessor systems, drivers may be initializated in another CPU while the rest of the kernels runs in the the main one.

However this feature is experimental, and for now it's only supported by the PCI subsystem. Some PCI drivers can not properly handle running in this way, and others might decide to blow up power supplies with a huge load all at once, so use this option at your own risk.

 * Add infrastructure to track "maximum allowable latency" for power saving policies. The reason for adding this infrastructure is that power management in the idle loop needs to make a tradeoff between latency and power savings (deeper power save modes have a longer latency to running code again). The code that today makes this tradeoff just does a rather simple algorithm; however this is not good enough: There are devices and use cases where a lower latency is required than that the higher power saving states provide. An example would be audio playback, but another example is the ipw2100 wireless driver that right now has a very direct and ugly acpi hook to disable some higher power states randomly when it gets certain types of error. The proposed solution is to have an interface where drivers can 1) announce the maximum latency (in microseconds) that they can deal with 2) modify this latency 3) give up their constraint [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=5c87579e65ee4f419b2369407f82326d38b5d2d8 (commit)], [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=9442e691e4aec85eba43ac60a3e77c77fd2e73a4 (commit)]

 * Non lazy "sleazy" fpu implementation. Right now the kernel on x86-64 has a 100% lazy fpu behavior: after *every* context switch a trap is taken for the first FPU use to restore the FPU context lazily. This is great for applications that have very sporadic or no FPU use (since then you avoid doing the expensive save/restore all the time). However for very frequent FPU users...  you take an extra trap every context switch. So 2.6.19 adds a simple heuristic to this code: After 5 consecutive context switches of FPU use, the lazy behavior is disabled and the context gets restored every context switch. If the app indeed uses the FPU, the trap is avoided.  (the chance of the 6th time slice using FPU after the previous 5 having done so are quite high obviously). After 256 switches, this is reset and lazy behavior is returned (until there are 5 consecutive ones again) [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=e07e23e1fd3000289fc7ccc6c71879070d3b19e0 (commit)]

-         Description of changes:
    
    A "sid" member has been added to the flow cache key resulting in the
    sid being available at all needed locations and the flow cache lookups
    automatically using the sid. The flow sid is derived from the socket
    on the outbound and the SAs (unlabeled where an SA was not used) on
    the inbound.
    
    Outbound case:
    1. Find policy for the socket.
    
    2. OLD: Find an SA that matches the policy.
     NEW: Find an SA that matches BOTH the policy and the flow/socket.
       This is necessary since not every SA that matches the policy
       can be used for the flow/socket. Consider policy range Secret-TS,
       and SAs each for Secret and TS. We don't want a TS socket to
       use the Secret SA. Hence the additional check for the SA Vs. flow/socket.
    
    3. NEW: When looking thru bundles for a policy, make sure the
            flow/socket can use the bundle. If a bundle is not found,
            create one, calling for IKE if necessary. If using IKE,
            include the security context in the acquire message to the IKE
            daemon.
    
    Inbound case:
    1. OLD: Find policy for the socket.
     NEW: Find policy for the incoming packet based on the sid of the
          SA(s) it used or the unlabeled sid if no SAs were
          used. (Consider a case where a socket is "authorized" for two
          policies (unclassified-confidential, secret-top_secret). If the
          packet has come in using a secret SA, we really ought to be
          using the latter policy (secret-top_secret).)
    
    2. OLD: BUG: No check to see if the SAs used by the packet agree with
                 the policy sec_ctx-wise.
    
                 (It was indicated in selinux_xfrm_sock_rcv_skb() that
                  this was being accomplished by
                  (x->id.spi == tmpl->id.spi || !tmpl->id.spi) in xfrm_state_ok,
           but it turns out tmpl->id.spi
                  would normally be zero (unless xfrm policy rules specify one
                  at the template level, which they usually don't).
     NEW: The socket is checked for access to the SAs used (based on the
          sid of the SAs) in selinux_xfrm_sock_rcv_skb().
    
    Forward case:
     This would be Step 1 from the Inbound case, followed by Steps 2 and 3
    from the Outbound case.
    
    Outstanding items/issues:
    
    - Timewait acknowledgements and such are generated in the
      current/upstream implementation using a NULL socket resulting in the
      any_socket sid (SYSTEM_HIGH) to be used. This problem is not addressed
      by this patch set.
    
    This patch: Add new flask definitions to SELinux
    
    Adds a new avperm "polmatch" to arbitrate flow/state access to a xfrm
    policy rule.

* [PATCH] selinux: add support for range transitions on object classes:    Introduces support for policy version 21.  This version of the binary
    kernel policy allows for defining range transitions on security classes
    other than the process security class.  As always, backwards compatibility
    for older formats is retained.  The security class is read in as specified
    when using the new format, while the "process" security class is assumed
    when using an older policy format.

* [PATCH] selinux: enable configuration of max policy version:    Enable configuration of SELinux maximum supported policy version to support
    legacy userland (init) that does not gracefully handle kernels that support
    newer policy versions two or more beyond the installed policy, as in FC3
    and FC4.

* [PATCH] SELinux: support mls categories for context mounts:    Allows commas to be embedded into context mount options (i.e.  "-o
    context=some_selinux_context_t"), to better support multiple categories,
    which are separated by commas and confuse mount.

    For example, with the current code:

      mount -t iso9660 /dev/cdrom /media/cdrom -o \
      ro,context=system_u:object_r:iso9660_t:s0:c1,c3,c4,exec

    The context option that will be interpreted by SELinux is
    context=system_u:object_r:iso9660_t:s0:c1

    instead of
    context=system_u:object_r:iso9660_t:s0:c1,c3,c4

    The options that will be passed on to the file system will be
    ro,c3,c4,exec.

    The proposed solution is to allow/require the SELinux context option
    specified to mount to use quotes when the context contains a comma.

    This patch modifies the option parsing in parse_opts(), contained in
    mount.c, to take options after finding a comma only if it hasn't seen a
    quote or if the quotes are matched.  It also introduces a new function that
    will strip the quotes from the context option prior to translation.  The
    quotes are replaced after the translation is completed to insure that in
    the event the raw context contains commas the kernel will be able to
    interpret the correct context.

-* [PATCH] AVR32 MTD: Static Memory Controller driver:    This patchset adds the necessary drivers and infrastructure to access the
    external flash on the ATSTK1000 board through the MTD subsystem.  With this
    stuff in place, it will be possible to use a jffs2 filesystem stored in the
    external flash as a root filesystem.  It might also be possible to update the
    boot loader if you drop the write protection of partition 0.
    
    As suggested by David Woodhouse, I reworked the patches to use the physmap
    driver instead of introducing a separate mapping driver for the ATSTK1000.
    I've also cleaned up the hsmc header by removing useless comments and
    converting spaces to tabs (my headerfile generator needs some work.)
    
    Unfortunately, I couldn't unlock the flash in fixup_use_atmel_lock because the
    erase regions hadn't been set up yet, so I had to do it from cfi_amdstd_setup
    instead.
    
    This patch:
    
    This adds a simple API for configuring the static memory controller along with
    an implementation for the Atmel HSMC.

* [PATCH] AVR32 MTD: AT49BV6416 platform device for ATSTK1000:    FRegister a platform device for the AT49BV6416 NOR flash chip on the ATSTK1000
    development board for use by the physmap MTD driver.
    
    The SMC timings are set up before the platform device is registered so that no
    board-specific mapping driver is necessary.
