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.

EXT 4

EXT 4 is a evolution (not a redesign) of EXT3

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

- dynamic slab reclaim: currently slab reclaim is enabled by setting an explicit option in /proc/sys/vm/zone_reclaim_mode and its used as a final option if the freeing of unmapped file backed pages is not enough to free enough pages to allow a local allocation.

* 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)]

* [PATCH] paravirt: lazy mmu mode hooks.patch: Implement lazy MMU update hooks which are SMP safe for both direct and shadow

page tables. The idea is that PTE updates and page invalidations while in lazy mode can be batched into a single hypercall. We use this in VMI for shadow page table synchronization, and it is a win. It also can be used by PPC and for direct page tables on Xen. For SMP, the enter / leave must happen under protection of the page table locks for page tables which are being modified. This is because otherwise, you end up with stale state in the batched hypercall, which other CPUs can race ahead of. Doing this under the protection of the locks guarantees the synchronization is correct, and also means that spurious faults which are generated during this window by remote CPUs are properly handled, as the page fault handler must re-check the PTE under protection of the same lock.

Considering it is PAE specific, and the accessor is i386 specific, I didn't want to add a generic encapsulation of this behavior yet.

* [PATCH] paravirt: kpte flush: Create a new PTE function which combines clearing a kernel PTE with the

subsequent flush. This allows the two to be easily combined into a single hypercall or paravirt-op. More subtly, reverse the order of the flush for kmap_atomic. Instead of flushing on establishing a mapping, flush on clearing a mapping. This eliminates the possibility of leaving stale kmap entries which may still have valid TLB mappings. This is required for direct mode hypervisors, which need to reprotect all mappings of a given page when changing the page type from a normal page to a protected page (such as a page table or descriptor table page). But it also provides some nicer semantics for real hardware, by providing extra debug-proofing against using stale mappings, as well as ensuring that no stale mappings exist when changing the cacheability attributes of a page, which could lead to cache conflicts when two different types of mappings exist for the same page.

* [PATCH] paravirt: combine flush accessed dirty.patch: Remove ptep_test_and_clear_{dirty|young} from i386, and instead use the

dominating functions, ptep_clear_flush_{dirty|young}. This allows the TLB page flush to be contained in the same macro, and allows for an eager optimization - if reading the PTE initially returned dirty/accessed, we can assume the fact that no subsequent update to the PTE which cleared accessed / dirty has occurred, as the only way A/D bits can change without holding the page table lock is if a remote processor clears them. This eliminates an extra branch which came from the generic version of the code, as we know that no other CPU could have cleared the A/D bit, so the flush will always be needed. We still export these two defines, even though we do not actually define the macros in the i386 code:
- #define HAVE_ARCH_PTEP_TEST_AND_CLEAR_YOUNG #define HAVE_ARCH_PTEP_TEST_AND_CLEAR_DIRTY
The reason for this is that the only use of these functions is within the generic clear_flush functions, and we want a strong guarantee that there are no other users of these functions, so we want to prevent the generic code from defining them for us.

* [PATCH] paravirt: optimize ptep establish for pae: The ptep_establish macro is only used on user-level PTEs, for P->P mapping

changes. Since these always happen under protection of the pagetable lock, the strong synchronization of a 64-bit cmpxchg is not needed, in fact, not even a lock prefix needs to be used. We can simply instead clear the P-bit, followed by a normal set. The write ordering is still important to avoid the possibility of the TLB snooping a partially written PTE and getting a bad mapping installed.

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:-)

-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, and everyone is happy. And nobody flames the kernel or GFS2 developers. Amazing, isn't?

* 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)]

* [PATCH] paravirt: lazy mmu mode hooks.patch:    Implement lazy MMU update hooks which are SMP safe for both direct and shadow
    page tables.  The idea is that PTE updates and page invalidations while in
    lazy mode can be batched into a single hypercall.  We use this in VMI for
    shadow page table synchronization, and it is a win.  It also can be used by
    PPC and for direct page tables on Xen.
    
    For SMP, the enter / leave must happen under protection of the page table
    locks for page tables which are being modified.  This is because otherwise,
    you end up with stale state in the batched hypercall, which other CPUs can
    race ahead of.  Doing this under the protection of the locks guarantees the
    synchronization is correct, and also means that spurious faults which are
    generated during this window by remote CPUs are properly handled, as the page
    fault handler must re-check the PTE under protection of the same lock.

* [PATCH] paravirt: update pte hook:    Add a pte_update_hook which notifies about pte changes that have been made

    shadows.
    
    It also turns out, there was one pte update in PAE mode that wasn't using any
    accessor interface at all for setting NX protection.  Considering it is PAE
    specific, and the accessor is i386 specific, I didn't want to add a generic
    encapsulation of this behavior yet.

* [PATCH] paravirt: kpte flush:    Create a new PTE function which combines clearing a kernel PTE with the
    subsequent flush.  This allows the two to be easily combined into a single
    hypercall or paravirt-op.  More subtly, reverse the order of the flush for
    kmap_atomic.  Instead of flushing on establishing a mapping, flush on clearing
    a mapping.  This eliminates the possibility of leaving stale kmap entries
    which may still have valid TLB mappings.  This is required for direct mode
    hypervisors, which need to reprotect all mappings of a given page when
    changing the page type from a normal page to a protected page (such as a page
    table or descriptor table page).  But it also provides some nicer semantics
    for real hardware, by providing extra debug-proofing against using stale
    mappings, as well as ensuring that no stale mappings exist when changing the
    cacheability attributes of a page, which could lead to cache conflicts when
    two different types of mappings exist for the same page.

* [PATCH] paravirt: combine flush accessed dirty.patch:    Remove ptep_test_and_clear_{dirty|young} from i386, and instead use the
    dominating functions, ptep_clear_flush_{dirty|young}.  This allows the TLB
    page flush to be contained in the same macro, and allows for an eager
    optimization - if reading the PTE initially returned dirty/accessed, we can
    assume the fact that no subsequent update to the PTE which cleared accessed /
    dirty has occurred, as the only way A/D bits can change without holding the
    page table lock is if a remote processor clears them.  This eliminates an
    extra branch which came from the generic version of the code, as we know that
    no other CPU could have cleared the A/D bit, so the flush will always be
    needed.
    
    We still export these two defines, even though we do not actually define
    the macros in the i386 code:
    
     #define __HAVE_ARCH_PTEP_TEST_AND_CLEAR_YOUNG
     #define __HAVE_ARCH_PTEP_TEST_AND_CLEAR_DIRTY
    
    The reason for this is that the only use of these functions is within the
    generic clear_flush functions, and we want a strong guarantee that there
    are no other users of these functions, so we want to prevent the generic
    code from defining them for us.

    set_pte_atomic from other architectures which falesly duplicated it, and

* [PATCH] paravirt: optimize ptep establish for pae:    The ptep_establish macro is only used on user-level PTEs, for P->P mapping
    changes.  Since these always happen under protection of the pagetable lock,
    the strong synchronization of a 64-bit cmpxchg is not needed, in fact, not
    even a lock prefix needs to be used.  We can simply instead clear the P-bit,
    followed by a normal set.  The write ordering is still important to avoid the
    possibility of the TLB snooping a partially written PTE and getting a bad
    mapping installed.

* [PATCH] Add the __stack_chk_fail() function:    GCC emits a call to a __stack_chk_fail() function when the stack canary is
    not matching the expected value.
    
    Since this is a bad security issue; lets panic the kernel rather than limping
    along; the kernel really can't be trusted anymore when this happens.

* [PATCH] 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 of course 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.
    
    The patch below 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).  The reason for this is to give apps
    that do longer bursts of FPU use still the lazy behavior back after some
    time.

* [PATCH] Add the -fstack-protector option to the CFLAGS:    Add a feature check that checks that the gcc compiler has stack-protector
    support and has the bugfix for PR28281 to make this work in kernel mode.
    The easiest solution I could find was to have a shell script in scripts/
    to do the detection; if needed we can make this fancier in the future
    without making the makefile too complex.

* [PATCH] x86: Allow disabling early pci scans with pci=noearly or disallowing conf1:    Some buggy systems can machine check when config space accesses
    happen for some non existent devices.  i386/x86-64 do some early
    device scans that might trigger this. Allow pci=noearly to disable
    this. Also when type 1 is disabling also don't do any early
    accesses which are always type1.
    
    This moves the pci= configuration parsing to be a early parameter.
    I don't think this can break anything because it only changes
    a single global that is only used by PCI.

* [PATCH] x86 microcode: add sysfs and hotplug support:    Add sysfs support.  Currently each CPU has three microcode related
    attributes.  One is 'version' which shows current ucode version of CPU.
    Tools can use the attribute do validation or show CPU ucode status.  one is
    'reload' which allows manually reloading ucode.  Another is
    'processor_flags', which exports processor flags, so we can write tools to
    check if CPU has latest ucode.  Also add suspend/resume and CPU hotplug
    support.

* Zoned counters: Support NR_SLAB_RECLAIMABLE / NR_SLAB_UNRECLAIMABLE [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=972d1a7b140569084439a81265a0f15b74e924e0 (commit)]

* zone_reclaim: dynamic slab reclaim:    Currently slab reclaim is enabled by setting an explicit option in /proc/sys/vm/zone_reclaim_mode and its used as a final option if the freeing of unmapped file backed pages is not enough to free enough pages to allow a local allocation. However, that means that the slab can grow excessively and that most memory of a node may be used by slabs. This implements slab reclaim during zone reclaim (zone reclaim occurs if there is a danger of an off node allocation).

At that point we:
    1. Shrink the per node page cache if the number of pagecache
       pages is more than min_unmapped_ratio percent of pages in a zone.
    
    2. Shrink the slab cache if the number of the nodes reclaimable slab pages
       (patch depends on earlier one that implements that counter)
       are more than min_slab_ratio (a new /proc/sys/vm tunable).
    
The default for the min_slab_ratio is 5%, and the slab option from /proc/sys/vm/zone_reclaim_mode is removed [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=0ff38490c836dc379ff7ec45b10a15a662f4e5f6 (commit)]

* [PATCH] Account for holes that are outside the range of physical memory:    absent_pages_in_range() made the assumption that users of the API would not

    holes correctly.

* [PATCH] Account for memmap and optionally the kernel image as holes:    The x86_64 code accounted for memmap and some portions of the the DMA zone as
    holes.  This was because those areas would never be reclaimed and accounting
    for them as memory affects min watermarks.  This patch will account for the
    memmap as a memory hole.  Architectures may optionally use set_dma_reserve()
    if they wish to account for a portion of memory in ZONE_DMA as a hole.

* [PATCH] Allow an arch to expand node boundaries:    Arch-independent zone-sizing determines the size of a node
    (pgdat->node_spanned_pages) based on the physical memory that was
    registered by the architecture.  However, when
    CONFIG_MEMORY_HOTPLUG_RESERVE is set, the architecture expects that the
    spanned_pages will be much larger and that mem_map will be allocated that
    is used lated on memory hot-add.
    
    This patch allows an architecture that sets CONFIG_MEMORY_HOTPLUG_RESERVE
    to call push_node_boundaries() which will set the node beginning and end to
    at *least* the requested boundary.

* [PATCH] vm: add per-zone writeout counter:    The VM is supposed to minimise the number of pages which get written off the

    So add `nr_vmscan_write' to /proc/vmstat and /proc/zoneinfo - the number of

    As compared to git-net-selinux_xfrm_decode_session-build-fix.patch in
    -mm, this patch sets the return parameter sid to SECSID_NULL in
    selinux_xfrm_decode_session() and handles this value in the caller
    selinux_inet_conn_request() appropriately.
