It holds a number of\n low level bits with no/few dependencies that are commonly used (eg.\n memory barriers) and a number of bits with more dependencies that\n aren\u0027t used in many places (eg. switch_to()).\n\n These patches break asm/system.h up into the following core pieces:\n\n (1) asm/barrier.h\n\n Move memory barriers here. This already done for MIPS and Alpha.\n\n (2) asm/switch_to.h\n\n Move switch_to() and related stuff here.\n\n (3) asm/exec.h\n\n Move arch_align_stack() here.

\u003clinux/bug.h\u003e file. Due to historical reasons, we have some BUG code\n in bug.h and some in kernel.h -- i.e. the support for BUILD_BUG in\n linux/kernel.h predates the addition of linux/bug.h, but old code in\n kernel.h wasn\u0027t moved to bug.h at that time. As a band-aid, kernel.h\n was including \u003casm/bug.h\u003e to pseudo link them.\n\n This has caused confusion[1] and general yuck/WTF[2] reactions.

[We\u0027ve not kernel.h for BUILD_BUG_ON.] Ugh -\n very confusing for someone who is new to kernel development.\n\n With the above in mind, the goals of this changeset are:\n\n 1) find and fix any include/*.h files that were relying on the\n implicit presence of BUG code.\n 2) find and fix any C files that were consuming kernel.h and hence\n relying on implicitly getting some/all BUG code.\n 3) Move the BUG related code living in kernel.h to \u003clinux/bug.h\u003e\n 4) remove the asm/bug.h from kernel.h to finally break the chain.\n\n During development, the order was more like 3-4, build-test, 1-2.

There are already a number of filter flags in\n/proc/\u003cpid\u003e/coredump_filter, however, these allow one to specify \u0027types\u0027\nof kernel memory, not specific address ranges (which is needed in this\ncase).\n\nSince there are no more vma flags available, the first patch eliminates\nthe need for the \u0027VM_ALWAYSDUMP\u0027 flag. The flag is used internally by\nthe kernel to mark vdso and vsyscall pages. However, it is simple\nenough to check if a vma covers a vdso or vsyscall page without the need\nfor this flag.\n\nThe second patch then replaces the \u0027VM_ALWAYSDUMP\u0027 flag with a new\n\u0027VM_NODUMP\u0027 flag, which can be set by userspace using new madvise flags:\n\u0027MADV_DONTDUMP\u0027, and unset via \u0027MADV_DODUMP\u0027. The core dump filters\ncontinue to work the same as before unless \u0027MADV_DONTDUMP\u0027 is set on the\nregion.\n\nThe qemu code which implements this features is at:\n\n http://people.redhat.com/~jbaron/qemu-dump/qemu-dump.patch\n\nIn my testing the qemu core dump shrunk from 383MB -\u003e 13MB with this\npatch.\n\nI also believe that the \u0027MADV_DONTDUMP\u0027 flag might be useful for\nsecurity sensitive apps, which might want to select which areas are\ndumped.\n\nThis patch:\n\nThe VM_ALWAYSDUMP flag is currently used by the coredump code to\nindicate that a vma is part of a vsyscall or vdso section.

The changes are\n well contained and just plug into the driver new gpu functionality\n so they should be fairly regression proof. I just want to give\n them a bit of a run on the hw AMD kindly sent me.\n\n b) drm prime/dma-buf interface code. This is just infrastructure\n code to expose the dma-buf stuff to drm drivers and to userspace.\n I\u0027m not planning on pushing any driver support in this cycle\n (except maybe exynos), but I\u0027d like to get the infrastructure code\n in so for the next cycle I can start getting the driver support\n into the individual drivers. We have started driver support for\n i915, nouveau and udl along with I think exynos and omap in\n staging. However this code relies on the dma-buf tree being\n pulled into your tree first since it needs the latest interfaces\n from that tree. I\u0027ll push to get that tree sent asap.\n\n (oh and any warnings you see in i915 are gcc\u0027s fault from what anyone\n can see).\"\n\nFix up trivial conflicts in arch/x86/platform/mrst/mrst.c due to the new\nmsic_thermal_platform_data() thermal function being added next to the\ntc35876x_platform_data() i2c device function..\n\n* \u0027drm-next\u0027 of git://people.freedesktop.org/~airlied/linux: (326 commits)\n drm/i915: use DDC_ADDR instead of hard-coding it\n drm/radeon: use DDC_ADDR instead of hard-coding it\n drm: remove unneeded redefinition of DDC_ADDR\n drm/exynos: added virtual display driver.\n drm: allow loading an EDID as firmware to override broken monitor\n drm/exynos: enable hdmi audio feature\n drm/exynos: add default pixel format for plane\n drm/exynos: cleanup exynos_hdmi.h\n drm/exynos: add is_local member in exynos_drm_subdrv struct\n drm/exynos: add subdrv open/close functions\n drm/exynos: remove module of exynos drm subdrv\n drm/exynos: release pending pageflip events when closed\n drm/exynos: added new funtion to get/put dma address.\n drm/exynos: update gem and buffer framework.\n drm/exynos: added mode_fixup feature and code clean.\n drm/exynos: add HDMI version 1.4 support\n drm/exynos: remove exynos_mixer.h\n gma500: Fix mmap frambuffer\n drm/radeon: Drop radeon_gem_object_(un)pin.\n drm/radeon: Restrict offset for legacy display engine.\n ...\n" }, { "commit": "639077fb69aec8112e5427210a83d0fb192969f0", "tree": "31513fea8a3a7eaa4d2db10194c0435cf2395d20", "parents": [ "c16fa4f2ad19908a47c63d8fa436a1178438c7e7" ], "author": { "name": "Jan Kiszka", "email": "jan.kiszka@siemens.com", "time": "Mon Mar 19 15:16:48 2012 -0500" }, "committer": { "name": "Jason Wessel", "email": "jason.wessel@windriver.com", "time": "Thu Mar 22 15:07:15 2012 -0500" }, "message": "kgdb: x86: Return all segment registers also in 64-bit mode\n\nEven if the content is always 0, gdb expects us to return also ds,\nes, fs, and gs while in x86-64 mode.

In those cases the huge page faults can\nallocate hugepmds under pmd_none_or_clear_bad() and that can trigger a\nfalse positive from pmd_bad() that will not like to see a pmd\nmaterializing as trans huge.\n\nIt\u0027s not khugepaged causing the problem, khugepaged holds the mmap_sem\nin write mode (and all those sites must hold the mmap_sem in read mode\nto prevent pagetables to go away from under them, during code review it\nseems vm86 mode on 32bit kernels requires that too unless it\u0027s\nrestricted to 1 thread per process or UP builds). The race is only with\nthe huge pagefaults that can convert a pmd_none() into a\npmd_trans_huge().\n\nEffectively all these pmd_none_or_clear_bad() sites running with\nmmap_sem in read mode are somewhat speculative with the page faults, and\nthe result is always undefined when they run simultaneously. This is\nprobably why it wasn\u0027t common to run into this. For example if the\nmadvise(MADV_DONTNEED) runs zap_page_range() shortly before the page\nfault, the hugepage will not be zapped, if the page fault runs first it\nwill be zapped.\n\nAltering pmd_bad() not to error out if it finds hugepmds won\u0027t be enough\nto fix this, because zap_pmd_range would then proceed to call\nzap_pte_range (which would be incorrect if the pmd become a\npmd_trans_huge()).\n\nThe simplest way to fix this is to read the pmd in the local stack\n(regardless of what we read, no need of actual CPU barriers, only\ncompiler barrier needed), and be sure it is not changing under the code\nthat computes its value. Even if the real pmd is changing under the\nvalue we hold on the stack, we don\u0027t care. If we actually end up in\nzap_pte_range it means the pmd was not none already and it was not huge,\nand it can\u0027t become huge from under us (khugepaged locking explained\nabove).\n\nAll we need is to enforce that there is no way anymore that in a code\npath like below, pmd_trans_huge can be false, but pmd_none_or_clear_bad\ncan run into a hugepmd. The overhead of a barrier() is just a compiler\ntweak and should not be measurable (I only added it for THP builds). I\ndon\u0027t exclude different compiler versions may have prevented the race\ntoo by caching the value of *pmd on the stack (that hasn\u0027t been\nverified, but it wouldn\u0027t be impossible considering\npmd_none_or_clear_bad, pmd_bad, pmd_trans_huge, pmd_none are all inlines\nand there\u0027s no external function called in between pmd_trans_huge and\npmd_none_or_clear_bad).\n\n\t\tif (pmd_trans_huge(*pmd)) {\n\t\t\tif (next-addr !\u003d HPAGE_PMD_SIZE) {\n\t\t\t\tVM_BUG_ON(!rwsem_is_locked(\u0026tlb-\u003emm-\u003emmap_sem));\n\t\t\t\tsplit_huge_page_pmd(vma-\u003evm_mm, pmd);\n\t\t\t} else if (zap_huge_pmd(tlb, vma, pmd, addr))\n\t\t\t\tcontinue;\n\t\t\t/* fall through */\n\t\t}\n\t\tif (pmd_none_or_clear_bad(pmd))\n\nBecause this race condition could be exercised without special\nprivileges this was reported in CVE-2012-1179.\n\nThe race was identified and fully explained by Ulrich who debugged it.\nI\u0027m quoting his accurate explanation below, for reference.\n\n\u003d\u003d\u003d\u003d\u003d\u003d start quote \u003d\u003d\u003d\u003d\u003d\u003d\u003d\n mapcount 0 page_mapcount 1\n kernel BUG at mm/huge_memory.c:1384!\n\n At some point prior to the panic, a \"bad pmd ...\" message similar to the\n following is logged on the console:\n\n mm/memory.c:145: bad pmd ffff8800376e1f98(80000000314000e7).\n\n The \"bad pmd ...\" message is logged by pmd_clear_bad() before it clears\n the page\u0027s PMD table entry.\n\n 143 void pmd_clear_bad(pmd_t *pmd)\n 144 {\n -\u003e 145 pmd_ERROR(*pmd);\n 146 pmd_clear(pmd);\n 147 }\n\n After the PMD table entry has been cleared, there is an inconsistency\n between the actual number of PMD table entries that are mapping the page\n and the page\u0027s map count (_mapcount field in struct page).

New \"hardware based branch profiling\" feature both on the kernel and\n the tooling side, on CPUs that support it. (modern x86 Intel CPUs\n with the \u0027LBR\u0027 hardware feature currently.)\n\n This new feature is basically a sophisticated \u0027magnifying glass\u0027 for\n branch execution - something that is pretty difficult to extract from\n regular, function histogram centric profiles.\n\n The simplest mode is activated via \u0027perf record -b\u0027, and the result\n looks like this in perf report:\n\n\t$ perf record -b any_call,u -e cycles:u branchy\n\n\t$ perf report -b --sort\u003dsymbol\n\t 52.34% [.] main [.] f1\n\t 24.04% [.] f1 [.] f3\n\t 23.60% [.] f1 [.] f2\n\t 0.01% [k] _IO_new_file_xsputn [k] _IO_file_overflow\n\t 0.01% [k] _IO_vfprintf_internal [k] _IO_new_file_xsputn\n\t 0.01% [k] _IO_vfprintf_internal [k] strchrnul\n\t 0.01% [k] __printf [k] _IO_vfprintf_internal\n\t 0.01% [k] main [k] __printf\n\n This output shows from/to branch columns and shows the highest\n percentage (from,to) jump combinations - i.e. the most likely taken\n branches in the system. \"branches\" can also include function calls\n and any other synchronous and asynchronous transitions of the\n instruction pointer that are not \u0027next instruction\u0027 - such as system\n calls, traps, interrupts, etc.\n\n This feature comes with (hopefully intuitive) flat ascii and TUI\n support in perf report.\n\n - Various \u0027perf annotate\u0027 visual improvements for us assembly junkies.\n It will now recognize function calls in the TUI and by hitting enter\n you can follow the call (recursively) and back, amongst other\n improvements.\n\n - Multiple threads/processes recording support in perf record, perf\n stat, perf top - which is activated via a comma-list of PIDs:\n\n\tperf top -p 21483,21485\n\tperf stat -p 21483,21485 -ddd\n\tperf record -p 21483,21485\n\n - Support for per UID views, via the --uid paramter to perf top, perf\n report, etc. For example \u0027perf top --uid mingo\u0027 will only show the\n tasks that I am running, excluding other users, root, etc.\n\n - Jump label restructurings and improvements - this includes the\n factoring out of the (hopefully much clearer) include/linux/static_key.h\n generic facility:\n\n\tstruct static_key key \u003d STATIC_KEY_INIT_FALSE;\n\n\t...\n\n\tif (static_key_false(\u0026key))\n\t do unlikely code\n\telse\n\t do likely code\n\n\t...\n\tstatic_key_slow_inc();\n\t...\n\tstatic_key_slow_inc();\n\t...\n\n The static_key_false() branch will be generated into the code with as\n little impact to the likely code path as possible. the\n static_key_slow_*() APIs flip the branch via live kernel code patching.\n\n This facility can now be used more widely within the kernel to\n micro-optimize hot branches whose likelihood matches the static-key\n usage and fast/slow cost patterns.\n\n - SW function tracer improvements: perf support and filtering support.\n\n - Various hardenings of the perf.data ABI, to make older perf.data\u0027s\n smoother on newer tool versions, to make new features integrate more\n smoothly, to support cross-endian recording/analyzing workflows\n better, etc.\n\n - Restructuring of the kprobes code, the splitting out of \u0027optprobes\u0027,\n and a corner case bugfix.\n\n - Allow the tracing of kernel console output (printk).\n\n - Improvements/fixes to user-space RDPMC support, allowing user-space\n self-profiling code to extract PMU counts without performing any\n system calls, while playing nice with the kernel side.\n\n - \u0027perf bench\u0027 improvements\n\n - ... and lots of internal restructurings, cleanups and fixes that made\n these features possible. And, as usual this list is incomplete as\n there were also lots of other improvements\n\n* \u0027perf-core-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (120 commits)\n perf report: Fix annotate double quit issue in branch view mode\n perf report: Remove duplicate annotate choice in branch view mode\n perf/x86: Prettify pmu config literals\n perf report: Enable TUI in branch view mode\n perf report: Auto-detect branch stack sampling mode\n perf record: Add HEADER_BRANCH_STACK tag\n perf record: Provide default branch stack sampling mode option\n perf tools: Make perf able to read files from older ABIs\n perf tools: Fix ABI compatibility bug in print_event_desc()\n perf tools: Enable reading of perf.data files from different ABI rev\n perf: Add ABI reference sizes\n perf report: Add support for taken branch sampling\n perf record: Add support for sampling taken branch\n perf tools: Add code to support PERF_SAMPLE_BRANCH_STACK\n x86/kprobes: Split out optprobe related code to kprobes-opt.c\n x86/kprobes: Fix a bug which can modify kernel code permanently\n x86/kprobes: Fix instruction recovery on optimized path\n perf: Add callback to flush branch_stack on context switch\n perf: Disable PERF_SAMPLE_BRANCH_* when not supported\n perf/x86: Add LBR software filter support for Intel CPUs\n ...\n" } ], "next": "0bbfcaff9b2a69c71a95e6902253487ab30cb498" }
