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 [http://lwn.net/Articles/91267/ opening the source code], since it was closed at Sistina). 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. (Amazing, isn't? In fact, 3 new filesystems are being merged in 2.6.19 and nobody is flaming nobody, quite the contrary)

EXT 4

EXT 4 is a evolution (not a redesign from zero) of EXT3. EXT3 never was, and never intended to be, a "state-of-the-art" filesystem (being fair, it was just about adding a journal to ext2 + some features like htree) but rather a solid, reliable filesystem. EXT3 has been quite succesful, and despite of the age of its design it works surprisingly quite well in a wide variety of workloads from modern desktops to some big iron SMPs (even if it's not "the best" in some of those workloads). EXT4 is a development and experimental feature. EXT4 will incorporate scalability and reliability enhancements for supporting large filesystems (64 bit) in keeping with increasing disk capacities and some of the "state-of-the-art" feature requirements. But the version in 2.6.19 it's missing lots of the features that are already developed but not merged, so it's not useful even for benchmarking. From the Section 2 of the [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob;f=Documentation/filesystems/ext4.txt Documentation file]:

Features currently available: ability to use filesystems > 16TB, extent format reduces metadata overhead (RAM, IO for access, transactions), extent format more robust in face of on-disk corruption due to magics, internal redundancy in tree

Candidate features for future inclusion: There are several under discussion, whether they all make it in is partly a function of how much time everyone has to work on them: improved file allocation (multi-block alloc, delayed alloc; basically done), fix 32000 subdirectory limit (patch exists, needs some e2fsck work), nsec timestamps for mtime, atime, ctime, create time (patch exists, needs some e2fsck work), inode version field on disk (NFSv4, Lustre; prototype exists), reduced mke2fs/e2fsck time via uninitialized groups (prototype exists), journal checksumming for robustness, performance (prototype exists), persistent file preallocation (e.g for streaming media, databases).

Features like metadata checksumming have been discussed and planned for a bit but no patches exist yet so I'm not sure they're in the near-term roadmap. The big performance win will come with mballoc and delalloc. CFS has been using mballoc for a few years already with Lustre, and IBM + Bull did a lot of benchmarking on it. The reason it isn't in the first set of patches is partly a manageability issue, and partly because it doesn't directly affect the on-disk format (outside of much better allocation) so it isn't critical to get into the first round of changes

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 for example. 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-based 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-based 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). [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=tree;f=drivers/ata (libata PATA code)]

It is probably worth reiterating that if you have SATA drives, and you do a make oldconfig from a 2.6.18 or previous kernel, your system will not boot unless you specifically go in and enable the new SATA subsystem, and the driver for your controller.

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

Sleepable RCU (Read Copy Update)

[http://lwn.net/Articles/202847/ (LWN article by Paul McKenney, who implemented it)]

Like in spinlocks, preemptable RCU read-side critical sections were prohibited. However, many people had frequently requested a "sleepable RCU". Furthermore, the realtime capabilities being 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)]

Configurable block layer

Not all embedded devices require it, some can make do with just JFFS2, NFS, ramfs, etc - none of which require the block layer to be present [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=9361401eb7619c033e2394e4f9f6d410d6719ac7 (commit 1], [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=51d7513a8a54e4210d358ff1dbd34daab99a6638 2], [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=cf9a2ae8d49948f861b56e5333530e491a9da190 3], [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=0d67a46df0125e20d14f12dbd3646f1f1bf23e8c 4], [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=b398f6bff93a247d2a7099e92905374966e4558f 5], [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=811d736f9e8013966e1a5a930c0db09508bdbb15 6], [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=07f3f05c1e3052b8656129b2a5aca9f888241a34 7], [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=831058dec3735665fe91bd0d37b6a8cf56b91abd 8], [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=7b0de42d7c5a471741ede4e71727d88000e6ea59 9], [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=65e6f5bc8149165efb9d7bdbd142bb837d5edfeb 10], [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=b71e8a4ce03b3098c7801ee5e6e08d1a39a226c2 11], [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=36695673b012096228ebdc1b39a6a5850daa474e 12], [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=52b499c438ff60991eb3855ca090782569b3e8cf 13], [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=e322ff07fb2d0f05c02d85e7c6b30d23f308c20f 14], [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=188f83dfe0eeecd1427d0d255cc97dbf7ef6b4b7 15], [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=52a700c5675f399c07e6e57328291e57f13ef3bb 16], [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=863d5b822c02d0e7215fb84ca79e9f8c3e35f04e 17], [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=d366e40a1cabd453be6e2609caa7e12f9ca17b1f 18], [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=4cb50dc2eaeddb0bc20bc4cd108c4fec99f5045a 19], [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=65934a9a028b88e83e2b0f8b36618fe503349f8e 20)]

Tracking maximum allowable latency for power saving

2.6.19 adds a infrastructure to track "maximum allowable latency" for power saving policies [http://lwn.net/Articles/197299/ (LWN article)]. 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)]

Arch-independent changes in the kernel core

• Memory management

  • Allow the removal of ZONE_DMA32 for non x86_64 architectures and ZONE_HIGHMEM for arches not using highmem (like 64 bit architectures). While they're not used on those arches, they eat some memory and they've no sense on those platforms anyway, so make it possible to disable them at compile time [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=776ed98b842ee8551793f842fe028c8091f3633e (commit)], [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=fb0e7942bdcbbd2f90e61cb4cfa4fa892a873f8a (commit)], [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=e53ef38d05dd59ed281a35590e4a5b64d8ff4c52 (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 tn here are 5 consecutive ones again) [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=e07e23e1fd3000289fc7ccc6c71879070d3b19e0 (commit)]

SELinux

• 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). 2.6.19 fixes 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 [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=51bd39860ff829475aef611a3234309e37e090d9 (commit)], [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=08554d6b33e60aa8ee40bbef94505941c0eefef2 (commit)], [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=4e2ba18eae7f370c7c3ed96eaca747cc9b39f917 (commit)], [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=b6340fcd761acf9249b3acbc95c4dc555d9beb07 (commit)], [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=4237c75c0a35535d7f9f2bfeeb4b4df1e068a0bf (commit)], [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=beb8d13bed80f8388f1a9a107d07ddd342e627e8 (commit)], [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=e0d1caa7b0d5f02e4f34aa09c695d04251310c6c (commit)], [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=0d681623d30c6565e8b62889f3aa3f4d4662c3e8 (commit)], [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=892c141e62982272b9c738b5520ad0e5e1ad7b42 (commit)], [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=cb969f072b6d67770b559617f14e767f47e77ece (commit)], [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=a51c64f1e5c2876eab2a32955acd9e8015c91c15 (commit)]
