mpls: Add a sysctl to control the size of the mpls label table
This sysctl gives two benefits. By defaulting the table size to 0 mpls even when compiled in and enabled defaults to not forwarding any packets. This prevents unpleasant surprises for users. The other benefit is that as mpls labels are allocated locally a dense table a small dense label table may be used which saves memory and is extremely simple and efficient to implement. This sysctl allows userspace to choose the restrictions on the label table size userspace applications need to cope with. Signed-off-by: "Eric W.

genirq / PM: better describe IRQF_NO_SUSPEND semantics
The IRQF_NO_SUSPEND flag is intended to be used for interrupts required to be enabled during the suspend-resume cycle. This mostly consists of IPIs and timer interrupts, potentially including chained irqchip interrupts if these are necessary to handle timers or IPIs. If an interrupt does not fall into one of the aforementioned categories, requesting it with IRQF_NO_SUSPEND is likely incorrect. Using IRQF_NO_SUSPEND does not guarantee that the interrupt can wake the system from a suspended state. For an interrupt to be able to trigger a wakeup, it may be necessary to program various components of the system. In these cases it is necessary to use {enable,disabled}_irq_wake. Unfortunately, several drivers assume that IRQF_NO_SUSPEND ensures that an IRQ can wake up the system, and the documentation can be read ambiguously w.r.t. this property. This patch updates the documentation regarding IRQF_NO_SUSPEND to make this caveat explicit, hopefully making future misuse rarer. Cleanup of existing misuse will occur as part of later patch series.

ipvs: allow rescheduling of new connections when port reuse is detected
Currently, when TCP/SCTP port reusing happens, IPVS will find the old entry and use it for the new one, behaving like a forced persistence. But if you consider a cluster with a heavy load of small connections, such reuse will happen often and may lead to a not optimal load balancing and might prevent a new node from getting a fair load. This patch introduces a new sysctl, conn_reuse_mode, that allows controlling how to proceed when port reuse is detected. The default value will allow rescheduling of new connections only if the old entry was in TIME_WAIT state for TCP or CLOSED for SCTP.

Pull MIPS updates from Ralf Baechle: "This is the main pull request for MIPS: - a number of fixes that didn't make the 3.19 release. - a number of cleanups. - preliminary support for Cavium's Octeon 3 SOCs which feature up to 48 MIPS64 R3 cores with FPU and hardware virtualization. - support for MIPS R6 processors. Revision 6 of the MIPS architecture is a major revision of the MIPS architecture which does away with many of original sins of the architecture such as branch delay slots. This and other changes in R6 require major changes throughout the entire MIPS core architecture code and make up for the lion share of this pull request. - finally some preparatory work for eXtendend Physical Address support, which allows support of up to 40 bit of physical address space on 32 bit processors" [ Ahh, MIPS can't leave the PAE brain damage alone.

The clock framework changes for 3.20 contain the usual driver additions,
enhancements and fixes mostly for ARM32, ARM64, MIPS and Power-based devices. Additionaly the framework core underwent a bit of surgery with two major changes. The boundary between the clock core and clock providers (e.g clock drivers) is now more well defined with dedicated provider helper functions. struct clk no longer maps 1:1 with the hardware clock but is a true per-user cookie which helps us tracker users of hardware clocks and debug bad behavior. The second major change is the addition of rate constraints for clocks. Rate ranges are now supported which are analogous to the voltage ranges in the regulator framework. Unfortunately these changes to the core created some breakeage. We think we fixed it all up but for this reason there are lots of last minute commits trying to undo the damage. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJU54D5AAoJEDqPOy9afJhJs6AQAK5YuUwjDchdpNZx9p7OnT1q +poehuUwE/gYjmdACqYFyaPrI/9f43iNCfFAgKGLQqmB5ZK4sm4ktzfBEhjWINR2 iiCx9QYMQVGiKwC8KU0ddeBciglE2b/DwxB45m9TsJEjowucUeBzwLEIj5DsGxf7 teXRoOWgXdz1MkQJ4pnA09Q3qEPQgmu8prhMfka/v75/yn7nb9VWiJ6seR2GqTKY sIKL9WbKjN4AzctggdqHnMSIqZoq6vew850bv2C1fPn7GiYFQfWW+jvMlVY40dp8 nNa2ixSQSIXVw4fCtZhTIZcIvZ8puc7WVLcl8fz3mUe3VJn1VaGs0E+Yd3GexpIV 7bwkTOIdS8gSRlsUaIPiMnUob5TUMmMqjF4KIh/AhP4dYrmVbU7Ie8ccvSxe31Ku lK7ww6BFv3KweTnW/58856ZXDlXLC6x3KT+Fw58L23VhPToFgYOdTxn8AVtE/LKP YR3UnY9BqFx6WHXVoNvg3Piyej7RH8fYmE9om8tyWc/Ab8Eo501SHs9l3b2J8snf w/5STd2CYxyKf1/9JLGnBvGo754O9NvdzBttRlygB14gCCtS/SDk/ELG2Ae+/a9P YgRk2+257h8PMD3qlp94dLidEZN4kYxP/J6oj0t1/TIkERWfZjzkg5tKn3/hEcU9 qM97ZBTplTm6FM+Dt/Vk =zCVK -----END PGP SIGNATURE----- Merge tag 'clk-for-linus-3.20' of git://git.linaro.org/people/mike.turquette/linux Pull clock framework updates from Mike Turquette: "The clock framework changes contain the usual driver additions, enhancements and fixes mostly for ARM32, ARM64, MIPS and Power-based devices.

watchdog: gpio_wdt: Add "always_running" feature to GPIO watchdog
On some chips, like the TPS386000, the trigger cannot be disabled and the CPU must keep toggling the line at all times. Add a switch "always_running" to keep toggling the GPIO line regardless of the state of the soft part of the watchdog. The "armed" member keeps track of whether a timeout must also cause a reset.

ARM: SoC platform changes
New and updated SoC support. Also included are some cleanups where the platform maintainers hadn't separated cleanups from new developent in separate branches. Some of the larger things worth pointing out: - A large set of changes from Alexandre Belloni and Nicolas Ferre preparing at91 platforms for multiplatform and cleaning up quite a bit in the process. - Removal of CSR's "Marco" SoC platform that never made it out to the market. We love seeing these since it means the vendor published support before product was out, which is exactly what we want! New platforms this release are: - Conexant Digicolor (CX92755 SoC) - Hisilicon HiP01 SoC - CSR/sirf Atlas7 SoC - ST STiH418 SoC - Common code changes for Nvidia Tegra132 (64-bit SoC) We're seeing more and more platforms having a harder time labelling changes as cleanups vs new development -- which is a good sign that we've come quite far on the cleanup effort.

dax: does not work correctly with virtual aliasing caches
The DAX code accesses the underlying storage through the kernel's linear mapping, which may not be cache-coherent with user mappings on ARM, MIPS or SPARC.

This support includes RTC time reading and setting, Alarm (1 minute accuracy) reading and setting, and battery low detection.

of: add vendor prefix for Abracon Corporation
This series adds support for Abracon AB-RTCMC-32.768kHz-B5ZE-S3 I2C RTC chip. Unlike many RTC chips, it includes an internal oscillator which spares room on the PCB. It also has some interesting features, like battery low detection (which the driver in this series supports). The only small "limitation" (mainly due to what RTC subsystem expects from RTC chips) is the fact that its alarm is accurate to the second. This series provides a solution (described below) for that limitation using another mechanism of the chip. I decided to split support between three different patches for this v0: - Patch 1/3: it simply references Abracon Corporation in vendor-prefixes documentation file. As Abracon has no NASDAQ ticker symbol; I have decided to use "abcn" (I initially started my work w/ "ab" but later changed for "abcn" which looked more meaningful) - Patch 2/3: it adds initial support for the chip and provides the ability to read/write time and also read/write alarm. As the alarm the chip provides is accurate to the minute, the support provided by this patch also has this limitation (e.g. UIE mode is not supported). - Patch 3/3: the chip supports a watchdog timer which can be used to extend the alarm mechanism in patch 2/3 in order to provide support for alarms under one minute (e.g. support UIE mode). In practice, the logic I implemented is to use the watchdog timer for alarms which are at most 4 minutes in the future and use the common alarm mechanism for alarms which are set to larger values. With that additional patch the device fully passes the rtctest.c program. I decided to split the driver between two patches (2 and 3 of 3) in order to ease review: patch 2 should be pretty straightforward to read for someone familiar w/ RTC subsystem. Patch 3 only extends what is in patch 2 regarding alarms.

rtc: rtc-isl12057: add isil,irq2-can-wakeup-machine property for in-tree users
Current in-tree users of ISL12057 RTC chip (NETGEAR ReadyNAS 102, 104 and 2120) do not have the IRQ#2 pin of the chip (associated w/ the Alarm1 mechanism) connected to their SoC, but to a PMIC (TPS65251 FWIW). This specific hardware configuration allows the NAS to wake up when the alarms rings. Recently introduced alarm support for ISL12057 relies on the provision of an "interrupts" property in system .dts file, which previous three users will never get. For that reason, alarm support on those devices is not function. To support this use case, this patch adds a new DT property for ISL12057 (isil,irq2-can-wakeup-machine) to indicate that the chip is capable of waking up the device using its IRQ#2 pin (even though it does not have its IRQ#2 pin connected directly to the SoC). This specific configuration was tested on a ReadyNAS 102 by setting an alarm, powering off the device and see it reboot as expected when the alarm rang w/: # echo `date '+%s' -d '+ 1 minutes'` > /sys/class/rtc/rtc0/wakealarm # shutdown -h now As a side note, the ISL12057 remains in the list of trivial devices, because the property is not per se required by the device to work but can help handle system w/ specific requirements. In exchange, the new feature is described in details in a specific documentation file.

kasan: enable instrumentation of global variables
This feature let us to detect accesses out of bounds of global variables. This will work as for globals in kernel image, so for globals in modules. Currently this won't work for symbols in user-specified sections (e.g. __init, __read_mostly, ...) The idea of this is simple. Compiler increases each global variable by redzone size and add constructors invoking __asan_register_globals() function. Information about global variable (address, size, size with redzone ...) passed to __asan_register_globals() so we could poison variable's redzone. This patch also forces module_alloc() to return 8*PAGE_SIZE aligned address making shadow memory handling ( kasan_module_alloc()/kasan_module_free() ) more simple. Such alignment guarantees that each shadow page backing modules address space correspond to only one module_alloc() allocation.

x86_64: add KASan support
This patch adds arch specific code for kernel address sanitizer. 16TB of virtual addressed used for shadow memory. It's located in range [ffffec0000000000 - fffffc0000000000] between vmemmap and %esp fixup stacks. At early stage we map whole shadow region with zero page. Latter, after pages mapped to direct mapping address range we unmap zero pages from corresponding shadow (see kasan_map_shadow()) and allocate and map a real shadow memory reusing vmemmap_populate() function. Also replace __pa with __pa_nodebug before shadow initialized. __pa with CONFIG_DEBUG_VIRTUAL=y make external function call (__phys_addr) __phys_addr is instrumented, so __asan_load could be called before shadow area initialized.

kasan: add kernel address sanitizer infrastructure
Kernel Address sanitizer (KASan) is a dynamic memory error detector. It provides fast and comprehensive solution for finding use-after-free and out-of-bounds bugs. KASAN uses compile-time instrumentation for checking every memory access, therefore GCC > v4.9.2 required. v4.9.2 almost works, but has issues with putting symbol aliases into the wrong section, which breaks kasan instrumentation of globals. This patch only adds infrastructure for kernel address sanitizer. It's not available for use yet. The idea and some code was borrowed from [1]. Basic idea: The main idea of KASAN is to use shadow memory to record whether each byte of memory is safe to access or not, and use compiler's instrumentation to check the shadow memory on each memory access. Address sanitizer uses 1/8 of the memory addressable in kernel for shadow memory and uses direct mapping with a scale and offset to translate a memory address to its corresponding shadow address. Here is function to translate address to corresponding shadow address: unsigned long kasan_mem_to_shadow(unsigned long addr) { return (addr >> KASAN_SHADOW_SCALE_SHIFT) + KASAN_SHADOW_OFFSET; } where KASAN_SHADOW_SCALE_SHIFT = 3. So for every 8 bytes there is one corresponding byte of shadow memory. The following encoding used for each shadow byte: 0 means that all 8 bytes of the corresponding memory region are valid for access; k (1 <= k <= 7) means that the first k bytes are valid for access, and other (8 - k) bytes are not; Any negative value indicates that the entire 8-bytes are inaccessible. Different negative values used to distinguish between different kinds of inaccessible memory (redzones, freed memory) (see mm/kasan/kasan.h). To be able to detect accesses to bad memory we need a special compiler. Such compiler inserts a specific function calls (__asan_load*(addr), __asan_store*(addr)) before each memory access of size 1, 2, 4, 8 or 16. These functions check whether memory region is valid to access or not by checking corresponding shadow memory. If access is not valid an error printed. Historical background of the address sanitizer from Dmitry Vyukov: "We've developed the set of tools, AddressSanitizer (Asan), ThreadSanitizer and MemorySanitizer, for user space. We actively use them for testing inside of Google (continuous testing, fuzzing, running prod services). To date the tools have found more than 10'000 scary bugs in Chromium, Google internal codebase and various open-source projects (Firefox, OpenSSL, gcc, clang, ffmpeg, MySQL and lots of others): [2] [3] [4]. The tools are part of both gcc and clang compilers. We have not yet done massive testing under the Kernel AddressSanitizer (it's kind of chicken and egg problem, you need it to be upstream to start applying it extensively). To date it has found about 50 bugs. Bugs that we've found in upstream kernel are listed in [5]. We've also found ~20 bugs in out internal version of the kernel. Also people from Samsung and Oracle have found some. [...] As others noted, the main feature of AddressSanitizer is its performance due to inline compiler instrumentation and simple linear shadow memory. User-space Asan has ~2x slowdown on computational programs and ~2x memory consumption increase. Taking into account that kernel usually consumes only small fraction of CPU and memory when running real user-space programs, I would expect that kernel Asan will have ~10-30% slowdown and similar memory consumption increase (when we finish all tuning). I agree that Asan can well replace kmemcheck. We have plans to start working on Kernel MemorySanitizer that finds uses of unitialized memory. Asan+Msan will provide feature-parity with kmemcheck. As others noted, Asan will unlikely replace debug slab and pagealloc that can be enabled at runtime. Asan uses compiler instrumentation, so even if it is disabled, it still incurs visible overheads. Asan technology is easily portable to other architectures. Compiler instrumentation is fully portable. Runtime has some arch-dependent parts like shadow mapping and atomic operation interception. They are relatively easy to port." Comparison with other debugging features: ======================================== KMEMCHECK: - KASan can do almost everything that kmemcheck can. KASan uses compile-time instrumentation, which makes it significantly faster than kmemcheck. The only advantage of kmemcheck over KASan is detection of uninitialized memory reads. Some brief performance testing showed that kasan could be x500-x600 times faster than kmemcheck: $ netperf -l 30 MIGRATED TCP STREAM TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to localhost (127.0.0.1) port 0 AF_INET Recv Send Send Socket Socket Message Elapsed Size Size Size Time Throughput bytes bytes bytes secs. 10^6bits/sec no debug: 87380 16384 16384 30.00 41624.72 kasan inline: 87380 16384 16384 30.00 12870.54 kasan outline: 87380 16384 16384 30.00 10586.39 kmemcheck: 87380 16384 16384 30.03 20.23 - Also kmemcheck couldn't work on several CPUs. It always sets number of CPUs to 1. KASan doesn't have such limitation. DEBUG_PAGEALLOC: - KASan is slower than DEBUG_PAGEALLOC, but KASan works on sub-page granularity level, so it able to find more bugs. SLUB_DEBUG (poisoning, redzones): - SLUB_DEBUG has lower overhead than KASan. - SLUB_DEBUG in most cases are not able to detect bad reads, KASan able to detect both reads and writes. - In some cases (e.g. redzone overwritten) SLUB_DEBUG detect bugs only on allocation/freeing of object. KASan catch bugs right before it will happen, so we always know exact place of first bad read/write.

Fairly small update, but there are some interesting new features.
Common: Optional support for adding a small amount of polling on each HLT instruction executed in the guest (or equivalent for other architectures). This can improve latency up to 50% on some scenarios (e.g. O_DSYNC writes or TCP_RR netperf tests). This also has to be enabled manually for now, but the plan is to auto-tune this in the future. ARM/ARM64: the highlights are support for GICv3 emulation and dirty page tracking s390: several optimizations and bugfixes. Also a first: a feature exposed by KVM (UUID and long guest name in /proc/sysinfo) before it is available in IBM's hypervisor! :) MIPS: Bugfixes. x86: Support for PML (page modification logging, a new feature in Broadwell Xeons that speeds up dirty page tracking), nested virtualization improvements (nested APICv---a nice optimization), usual round of emulation fixes. There is also a new option to reduce latency of the TSC deadline timer in the guest; this needs to be tuned manually. Some commits are common between this pull and Catalin's; I see you have already included his tree. ARM has other conflicts where functions are added in the same place by 3.19-rc and 3.20 patches.

fs: proc: task_mmu: show page size in /proc/<pid>/numa_maps
The output of /proc/$pid/numa_maps is in terms of number of pages like anon=22 or dirty=54. Here's some output: 7f4680000000 default file=/hugetlb/bigfile anon=50 dirty=50 N0=50 7f7659600000 default file=/anon_hugepage\040(deleted) anon=50 dirty=50 N0=50 7fff8d425000 default stack anon=50 dirty=50 N0=50 Looks like we have a stack and a couple of anonymous hugetlbfs areas page which both use the same amount of memory. They don't. The 'bigfile' uses 1GB pages and takes up ~50GB of space. The anon_hugepage uses 2MB pages and takes up ~100MB of space while the stack uses normal 4k pages. You can go over to smaps to figure out what the page size _really_ is with KernelPageSize or MMUPageSize. But, I think this is a pretty nasty and counterintuitive interface as it stands. This patch introduces 'kernelpagesize_kB' line element to /proc/<pid>/numa_maps report file in order to help identifying the size of pages that are backing memory areas mapped by a given task. This is specially useful to help differentiating between HUGE and GIGANTIC page backed VMAs.

The first user will be the ARM64 common DMA-API implementation for IOMMUs * Device tree support for Renesas IPMMU * Various fixes and cleanups all over the place -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (GNU/Linux) iQIcBAABAgAGBQJU3MJOAAoJECvwRC2XARrjopUP+wachFx8vb00M4hlnlwL6FCn DyIFkA1n4wL0muPhjcBI+LViEXrSxjr2TYoJEaBg+fiByWWQ1Hefg+KPz331Lo1D +uo7WiOa1AB3pfkQiUN9IN6xx+o6ivhb3UQPiL4FHjggB/qz+KVxMM9nx0j8o0fQ D9q6HLFiOIsFkra3xZaSuDGvYUBpcwyfn8FP1HVfvLlg1uxIGDcUJX3qU5UBpj9q al/lPZ4A7rp+JLApV6WyouPiyVOZKikb5x920KeRNBem7a9fNBdgf+x7QbKpNXa1 5MaT5MarwGe8lJE4wtjOqRtsllhia+A1rg/6JbROPrlGetRFiuIh2sCKLvwOCko/ IjBHSutpaRT1lFoAG0TAnXQlvHRG/58XxOlP3eF613X/p8/cezuUaTyTIwZam9X3 j2GWwbUcBiHTxlu7bQDPz6a7cTf4w6wEALzYl18QrAFv+2LqlCfOo/LSlpStmjrF kRN8DYaohlTULvmFneSr8rfGsnp5yPgIPvdmqiSwTz/Ih7kYPgfLy6+v6IAHUqZj 0n9oGs8eMqVvSzM2qqmyA9WGuQZRyhNjj4iDwn/he5YMw2kqxUQYGMpLnSu0Oi48 n4PqodtVol64jKLwaHZwyU8u71iyjUC5K9TDot/I2wlSRcTELJhxGh6c1sfDLyrO u/htIszgKCgFvVrQoEZB =dwrA -----END PGP SIGNATURE----- Merge tag 'iommu-updates-v3.20' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu Pull IOMMU updates from Joerg Roedel: "This time with: - Generic page-table framework for ARM IOMMUs using the LPAE page-table format, ARM-SMMU and Renesas IPMMU make use of it already. - Break out the IO virtual address allocator from the Intel IOMMU so that it can be used by other DMA-API implementations too.
