Merge branch 'next-integrity' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security
Pull integrity updates from James Morris: "In Linux 4.19, a new LSM hook named security_kernel_load_data was upstreamed, allowing LSMs and IMA to prevent the kexec_load syscall. Different signature verification methods exist for verifying the kexec'ed kernel image. This adds additional support in IMA to prevent loading unsigned kernel images via the kexec_load syscall, independently of the IMA policy rules, based on the runtime "secure boot" flag. An initial IMA kselftest is included. In addition, this pull request defines a new, separate keyring named ".platform" for storing the preboot/firmware keys needed for verifying the kexec'ed kernel image's signature and includes the associated IMA kexec usage of the ".platform" keyring. (David Howell's and Josh Boyer's patches for reading the preboot/firmware keys, which were previously posted for a different use case scenario, are included here)" * 'next-integrity' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security: integrity: Remove references to module keyring ima: Use inode_is_open_for_write ima: Support platform keyring for kernel appraisal efi: Allow the "db" UEFI variable to be suppressed efi: Import certificates from UEFI Secure Boot efi: Add an EFI signature blob parser efi: Add EFI signature data types integrity: Load certs to the platform keyring integrity: Define a trusted platform keyring selftests/ima: kexec_load syscall test ima: don't measure/appraise files on efivarfs x86/ima: retry detecting secure boot mode docs: Extend trusted keys documentation for TPM 2.0 x86/ima: define arch_get_ima_policy() for x86 ima: add support for arch specific policies ima: refactor ima_init_policy() ima: prevent kexec_load syscall based on runtime secureboot flag x86/ima: define arch_ima_get_secureboot integrity: support new struct public_key_signature encoding field |

IOMMU Updates for Linux v4.21
Including (in no particular order): - Page table code for AMD IOMMU now supports large pages where smaller page-sizes were mapped before. VFIO had to work around that in the past and I included a patch to remove it (acked by Alex Williamson) - Patches to unmodularize a couple of IOMMU drivers that would never work as modules anyway. - Work to unify the the iommu-related pointers in 'struct device' into one pointer. This work is not finished yet, but will probably be in the next cycle. - NUMA aware allocation in iommu-dma code - Support for r8a774a1 and r8a774c0 in the Renesas IOMMU driver - Scalable mode support for the Intel VT-d driver - PM runtime improvements for the ARM-SMMU driver - Support for the QCOM-SMMUv2 IOMMU hardware from Qualcom - Various smaller fixes and improvements -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAABAgAGBQJcKkEoAAoJECvwRC2XARrjCCoQAJxsgaAF5Z0s7z8j2A9SkaGp SIMnUAI5mDOdyhTOAI+eehpRzg5UVYt/JjFYnHz8HWqbSc8YOvDvHafmhMFIwYvO hq5knbs6ns2jJNFO+M4dioDq+3THdqkGIF5xoHdGTP7cn9+XyQ8lAoHo0RuL122U PJGqX7Cp4XnFP4HMb3uQYhVeBV7mU+XqAdB+4aDnQkzI5LkQCRr74GcqOm+Rlnyc cmQWc2arUMjgc1TJIrex8dx9dT6lq8kOmhyEg/IjHeGaZyJ3HqA+30XDDLEExN0G MeVawuxJz40HgXlkXr+iZTQtIFYkXdKvJH6rptMbOfbDeDz+YZ01TbtAMMH9o4jX yxjjMjdcWTsWYQ/MHHdsoMP34cajCi/EYPMNksbycw+E3Y+X/bSReCoWC0HUK8/+ Z4TpZ9mZVygtJR+QNZ+pE9oiJpb4sroM10zTnbMoVHNnvfsO01FYk7FMPkolSKLw zB4MDswQYgchoFR9Z4ZB4PycYTzeafLKYgDPDoD1vIJgDavuidwvDWDRTDc+aMWM siIIewq19To9jDJkVjX4dsT/p99KVKgAR/Ps6jjWkAroha7g6GcmlYZHIJnyop04 jiaSXUsk8aRucP/CRz5xdMmaGoN7BsNmpUjcrquc6Povk/6gvXvpY04oCs1+gNMX ipL9E3GTFCVBubRFrksv =DT9A -----END PGP SIGNATURE----- Merge tag 'iommu-updates-v4.21' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu Pull IOMMU updates from Joerg Roedel: - Page table code for AMD IOMMU now supports large pages where smaller page-sizes were mapped before.

kgdb patches for 4.20-rc1
Mostly clean ups although whilst Doug's was chasing down a odd
lockdep warning he also did some work to improved debugger resilience
when some CPUs fail to respond to the round up request.
The main changes are:
* Fixing a lockdep warning on architectures that cannot use an NMI for
the round up plus related changes to make CPU round up and all CPU
backtrace more resilient.
* Constify the arch ops tables
* A couple of other small clean ups
Two of the three patchsets here include changes that spill over into
arch/. Changes in the arch space are relatively narrow in scope
(and directly related to kgdb). Didn't get comprehensive acks but
all impacted maintainers were Cc:ed in good time.

KEYS: fix parsing invalid pkey info string
We need to check the return value of match_token() for Opt_err before doing anything with it. [ Not only did the old "-1" value for Opt_err cause problems for the __test_and_set_bit(), as fixed in commit |

ARM: SoC defconfig updates
Most changes here are to enable new drivers and platforms in the various configs that affect them. Most of these have been covered and described in the other branches, we mostly keep defconfig separate to avoid conflicts between SoC/dt/driver updates that they otherwise would be grouped with. One thing worth mentioning here is that OMAP changes from using their own UART driver, to 8250, for the multi_v7_defconfig shared config on 32-bit. This means that the console is now named ttyS* instead of ttyO*. This change was already done for omap2_defconfig a while back, so most users of these configs have either already updated, or can easily follow the same patterns as they did at that time. This makes platform support slightly easier for distros, since they no longer need to keep track of a separate console prefix for these platforms. -----BEGIN PGP SIGNATURE----- iQJDBAABCAAtFiEElf+HevZ4QCAJmMQ+jBrnPN6EHHcFAlwqg+4PHG9sb2ZAbGl4 b20ubmV0AAoJEIwa5zzehBx3nHcQAKrzSPsi3NWZHAIyP9Gcsu/mqebeB7ATnUVB EfsYl+0ZLwZjex2pI7YmDih4QgOui3caOYU3rlqcu+zTSXYp03GnzA/fuW/aOBr3 Y4UYQcUIJULJyYzE14y5MhYxMfedF5U4yfayQj/6Xn4dojSICb19/CxD7lEtxUBQ DqYizTnR5ABRVDnRXmgo0TcHCSa05xP5Hn48DL02fJUc1oHzv3RoH2MrC4j4a2QO k0INYeq9cRFv9kcuz4S0VRXDvpA6cLsa9RZ8I3eJ+tpDFK8HmNyrij98CQLBwb/S UzuC+DvD5MdJsf6Tp15enXIKtLKBtEQiXVncX5dCFLGW+lfZb0FyMa6Q4herGEL3 NLifwcxDwiATKJkGuQKJHhCnMVGanUz+fn+7nXbHtloOsR/2ttofaTFCCURN0Pr+ oIa79JSd58SES+Rqz7V17r08SuK5iMjF8XENDMuim095WIt2ysoKW7P11eq/CjNf qheaiBK/ANHeYaVLb6OG7V5SMjsxWYcUfvwONiA5Qs1HbjiOXamUBOAiBF8zMBZc rd21X2kqVpfU/IDgqhWTEawtl76gh9+1uCbbL5l+qiwyFfRw0b/9pakMs3szgD+v 2w49p/WwOQQoxzV5jCBlo36ZzKISrKGnTEQhRadtxCPPnrg/8emUNU6S/aHB2OmH x1Vehuja =65qL -----END PGP SIGNATURE----- Merge tag 'armsoc-defconfig' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC defconfig updates from Olof Johansson: "Most changes here are to enable new drivers and platforms in the various configs that affect them.

ARM: Device-tree updates
As usual, this is where the bulk of our changes end up landing each merge window. The individual updates are too many to enumerate, many many platforms have seen additions of device descriptions such that they are functionally more complete (in fact, this is often the bulk of updates we see). Instead I've mostly focused on highlighting the new platforms below as they are introduced. Sometimes the introduction is of mostly a fragment, that later gets filled in on later releases, and in some cases it's near-complete platform support. The latter is more common for derivative platforms that already has similar support in-tree. Two SoCs are slight outliers from the usual range of additions. Allwinner support for F1C100s, a quite old SoC (ARMv5-based) shipping in the Lychee Pi Nano platform. At the other end is NXP Layerscape LX2160A, a 16-core 2.2GHz Cortex-A72 SoC with a large amount of I/O aimed at infrastructure/networking. TI updates stick out in the diff stats too, in particular because they have moved the description of their L4 on-chip interconnect to devicetree, which opens up for removal of even more of their platform-specific 'hwmod' description tables over the next few releases. SoCs: - Qualcomm QCS404 (4x Cortex-A53) - Allwinner T3 (rebranded R40) and f1c100s (armv5) - NXP i.MX7ULP (1x Cortex-A7 + 1x Cortex-M4) - NXP LS1028A (2x Cortex-A72), LX2160A (16x Cortex-A72) New platforms: - Rockchip: Gru Scarlet (RK3188 Tablet) - Amlogic: Phicomm N1 (S905D), Libretech S805-AC - Broadcom: Linksys EA6500 v2 Wi-Fi router (BCM4708) - Qualcomm: QCS404 base platform and EVB - Qualcomm: Remove of Arrow SD600 - PXA: First PXA3xx DT board: Raumfeld - Aspeed: Facebook Backpack-CMM BMC - Renesas iWave G20D-Q7 (RZ/G1N) - Allwinner t3-cqa3t-bv3 (T3/R40) and Lichee Pi Nano (F1C100s) - Allwinner Emlid Neutis N5, Mapleboard MP130 - Marvell Macchiatobin Single Shot (Armada 8040, no 10GbE) - i.MX: mtrion emCON-MX6, imx6ul-pico-pi, imx7d-sdb-reva - VF610: Liebherr's BK4 device, ZII SCU4 AIB board - i.MX7D PICO Hobbit baseboard - i.MX7ULP EVK board - NXP LX2160AQDS and LX2160ARDB boards Other: - Coresight binding updates across the board - CPU cooling maps updates across the board -----BEGIN PGP SIGNATURE----- iQJDBAABCAAtFiEElf+HevZ4QCAJmMQ+jBrnPN6EHHcFAlwqgVYPHG9sb2ZAbGl4 b20ubmV0AAoJEIwa5zzehBx3ybAQAKAhd7XI5oY/wgdZZmxwcX+p7sU6LXeIlpWU XsPN1c14KU0siQv/znVA5OpF+fgn9eRqfWnMoDPlvdScTq07FM2NBmOJfVJYDPJa uvsll5m+84FCYanIR//YybS0tCM0b0BHoHo2DoyIxWeAwmw7BBVslddBdNg6R7hG S9rU9rUeqfCj7HbcPLqVn0DecMtEe7R8zmDtG1CSMqrhncifmoV4gtUnbYAg0GGT cSvj/zT8A1j0oJcU2Upl/Fr+7WJ7XB9pnku91nUOSXLv5VkyctLGomKq5F7O2/Xs 2DhpH2yKwQt7S7TDiDd0jy64Of6+Xup35wEHevCeKrzGXcVRqqHwCkanLz9FdjVt yg4UrI/P1nY7h4ifZPplgigv+kA+IjRGiMrTRIEgSE5YK9U5AYkgembTWksRDikd 5EpeJcMj2tBv4SDellNNtzh6GGTPBf3GJw3P9uRuxnQY/T31N2eX0XGeRikL+Lzf 9nbQdJealmql3rCa5oFEJwSxrSaAv/ub7/294kPdEmXj8+3qUuH3hZAZOI9LSXGW GCuxsgccB2GF1M48x48/QpHgxb93okyXmndONZnU8uN8ba0zS4b8QLwvIY5rqv5Z kqD1VPBQf9kGVyzDyABRjFmGCDJcoOJf4QrzvNk9+xo8fXVk1xNtxu4MUsHvc2lS cU2RYWm/ =sFVi -----END PGP SIGNATURE----- Merge tag 'armsoc-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM Device-tree updates from Olof Johansson: "As usual, this is where the bulk of our changes end up landing each merge window.

ARM: SoC platform updates
SoC updates, mostly refactorings and cleanups of old legacy platforms,
but also a few more things:
New SoC support this release:
- NXP/Freescale i.MX7ULP (1x Cortex-A7, Cortex-M4, graphics, etc)
- Allwinner F1C100, older platform with an ARM926-EJS (ARMv5) core
Cleanups of various platforms:
- OMAP1 ams-delta does some GPIO cleanups
- Davinci removes of at24 platform data
- Samsung cleans up old wakeup, PM debug and secondary core boot code
- Renesas moves around config options and PM code to drivers/soc for
sharing with 64-bit and more consistency
- i.MX, Broadcom and SoCFPGA all have tweaks to lowlevel debug console setups
- SoCFPGA adds explicit selection of ARM errata and removes some unused code
This tag also contains a few patches that I had queued up as fixes for
4.20 but didn't send in before the release.

Tracing changes for v4.21:
- Rework of the kprobe/uprobe and synthetic events to consolidate all
the dynamic event code. This will make changes in the future easier.
- Partial rewrite of the function graph tracing infrastructure.
This will allow for multiple users of hooking onto functions
to get the callback (return) of the function. This is the ground
work for having kprobes and function graph tracer using one code base.
- Clean up of the histogram code that will facilitate adding more
features to the histograms in the future.
- Addition of str_has_prefix() and a few use cases. There currently
is a similar function strstart() that is used in a few places, but
only returns a bool and not a length. These instances will be
removed in the future to use str_has_prefix() instead.
- A few other various clean ups as well.

kdb: Don't back trace on a cpu that didn't round up
If you have a CPU that fails to round up and then run 'btc' you'll end up crashing in kdb becaue we dereferenced NULL. Let's add a check. It's wise to also set the task to NULL when leaving the debugger so that if we fail to round up on a later entry into the debugger we won't backtrace a stale task.

kgdb: Don't round up a CPU that failed rounding up before
If we're using the default implementation of kgdb_roundup_cpus() that uses smp_call_function_single_async() we can end up hanging kgdb_roundup_cpus() if we try to round up a CPU that failed to round up before. Specifically smp_call_function_single_async() will try to wait on the csd lock for the CPU that we're trying to round up. If the previous round up never finished then that lock could still be held and we'll just sit there hanging. There's not a lot of use trying to round up a CPU that failed to round up before. Let's keep a flag that indicates whether the CPU started but didn't finish to round up before. If we see that flag set then we'll skip the next round up. In general we have a few goals here: - We never want to end up calling smp_call_function_single_async() when the csd is still locked. This is accomplished because flush_smp_call_function_queue() unlocks the csd _before_ invoking the callback. That means that when kgdb_nmicallback() runs we know for sure the the csd is no longer locked. Thus when we set "rounding_up = false" we know for sure that the csd is unlocked. - If there are no timeouts rounding up we should never skip a round up. NOTE #1: In general trying to continue running after failing to round up CPUs doesn't appear to be supported in the debugger. When I simulate this I find that kdb reports "Catastrophic error detected" when I try to continue. I can overrule and continue anyway, but it should be noted that we may be entering the land of dragons here. Possibly the "Catastrophic error detected" was added _because_ of the future failure to round up, but even so this is an area of the code that hasn't been strongly tested. NOTE #2: I did a bit of testing before and after this change. I introduced a 10 second hang in the kernel while holding a spinlock that I could invoke on a certain CPU with 'taskset -c 3 cat /sys/...". Before this change if I did: - Invoke hang - Enter debugger - g (which warns about Catastrophic error, g again to go anyway) - g - Enter debugger ...I'd hang the rest of the 10 seconds without getting a debugger prompt. After this change I end up in the debugger the 2nd time after only 1 second with the standard warning about 'Timed out waiting for secondary CPUs.' I'll also note that once the CPU finished waiting I could actually debug it (aka "btc" worked) I won't promise that everything works perfectly if the errant CPU comes back at just the wrong time (like as we're entering or exiting the debugger) but it certainly seems like an improvement. NOTE #3: setting 'kgdb_info[cpu].rounding_up = false' is in kgdb_nmicallback() instead of kgdb_call_nmi_hook() because some implementations override kgdb_call_nmi_hook(). It shouldn't hurt to have it in kgdb_nmicallback() in any case. NOTE #4: this logic is really only needed because there is no API call like "smp_try_call_function_single_async()" or "smp_csd_is_locked()". If such an API existed then we'd use it instead, but it seemed a bit much to add an API like this just for kgdb.

kgdb: Fix kgdb_roundup_cpus() for arches who used smp_call_function()

If nothing else that seems like it could violate spinlock semantics and cause a deadlock. Instead, let's use a private csd alongside smp_call_function_single_async() to round up the other CPUs. Using smp_call_function_single_async() doesn't require interrupts to be enabled so we can remove the offending bit of code. In order to avoid duplicating this across all the architectures that use the default kgdb_roundup_cpus(), we'll add a "weak" implementation to debug_core.c. Looking at all the people who previously had copies of this code, there were a few variants. I've attempted to keep the variants working like they used to. Specifically: * For arch/arc we passed NULL to kgdb_nmicallback() instead of get_irq_regs(). * For arch/mips there was a bit of extra code around kgdb_nmicallback() NOTE: In this patch we will still get into trouble if we try to round up a CPU that failed to round up before. We'll try to round it up again and potentially hang when we try to grab the csd lock. That's not new behavior but we'll still try to do better in a future patch.

kgdb: Remove irq flags from roundup

There is > local_irq_save() call before kgdb_roundup_cpus(). Nobody used those flags. Anyone who wanted to temporarily turn on interrupts just did local_irq_enable() and local_irq_disable() without looking at them. So we can definitely remove the flags.

Kconfig file consolidation for v4.21
Consolidation of bus (PCI, PCMCIA, EISA, RapidIO) config entries by Christoph Hellwig.

lib: don't depend on linux headers being installed.
gen_crc64table requires linux include files to be installed in
/usr/include/linux. This is a new requrement so hosts that could
previously build the kernel, now cannot.
gen_crc64table makes this requirement by including <linux/swab.h>, but
nothing from that header is actaully used.
So remove the #include, so that the linux headers no longer need to be
installed.
Fixes:

A fairly normal cycle for documentation stuff. We have a new
document on perf security, more Italian translations, more
improvements to the memory-management docs, improvements to the
pathname lookup documentation, and the usual array of smaller
