But it can cause the same tail region of the memory to\nbe unmapped twice (once in UnMapAtEnd() and once more in ~MemMap()\nduring a shutdown.)\n\nI encountered a crash because of this issue in SpaceTest.ZygoteTest\n(which happens to happen only on a device in a branch with the\nrosalloc change probably due to some randomness in mmap address\nchoice, etc.)\n\nHere\u0027s what happens:\n\n1) CreateZygoteSpace() will call UnMapAtEnd() and unmap the unused\ntail of the alloc space.\n\n2) In the same function, after UnMapAtEnd(), several libc new/malloc\nallocations, including a new DlMallocSpace object, happen. This\nhappens to cause libc to map a new memory region that overlaps with\nthe memory region that has just been unmapped in 1) and use it to\nallocate those allocations (that is, the new DlMallocSpace object is\nallocated in that memory region.) This is a second DlMallocSpace that\nbecomes the new alloc space after zygote fork. The first DlMallocSpace\nbecomes the zygote space. Note that that libc maps that memory region\nbefore the underlying memory of the second DlMallocSpace is mapped.\n\n3) During a Runtime shutdown (which happens once for a normal VM\nshutdown or at the end of each test run) all the spaces get destructed\nincluding the the two DlMallocSpaces one by one. When the first\nDlMallocSpace gets destructed (note the space list is sorted by\naddress,) its super destructor ~MemMap() unmaps the original memory\nregion that\u0027s already partially unmapped in 2). Now this memory region\nincludes the libc memory region that includes the second DlMallocSpace\nobject.\n\n4) When the second DlMallocSpace object gets attempted to be\ndestructed, the memory in which the object resides is already unmapped\nin 3) and causes a SIGSEGV.\n\nThis change replaces UnMapAtEnd() with a new function RemapAtEnd()\nwhich combines the unmapping of the tail region and remapping of it to\nachieve the following two things:\n\n1) Fixes this double unmap issue by updating the base_size_ member\nvariable to exclude the already-unmapped tail region so that ~MemMap()\nwill not unmap the tail region again.\n\n2) Improves on the non-atomicity issue in the unmap/map sequence in\nCreateZygoteSpace(). That is, once the unused tail portion of the\nmemory region of the origina alloc space is unmapped, something like\nlibc could come along and take that memory region, before the memory\nregion is mapped again for the new alloc space. This, as a result,\nwould make a hole between the old alloc (new zygote) space and the new\nalloc space and cause the two spaces to be\nnon-contiguous. RemapAtEnd() eliminates new/malloc allocations between\nthe unmap and the map calls. But note this still isn\u0027t perfect as\nother threads could in theory take the memory region between the\nmunmap and the mmap calls.\n\nAdded tests.\n\nChange-Id: I43bc3a33a2cbfc7a092890312e34aa5285384589\n" }, { "commit": "8d31bbd3d6536de12bc20e3d29cfe03fe848f9da", "tree": "2373ae08ddddaf1034623df85d647ecf9ac6c831", "parents": [ "57e6d8a99058e5c74d5244b68a5f4d53526fa108" ], "author": { "name": "Ian Rogers", "email": "irogers@google.com", "time": "Sun Oct 13 10:44:14 2013 -0700" }, "committer": { "name": "Ian Rogers", "email": "irogers@google.com", "time": "Mon Oct 21 17:01:11 2013 -0700" }, "message": "Throw IOException at source of failing to open a dex file.\n\nBefore is:\njava.lang.ClassNotFoundException: Didn\u0027t find class \"GCBench\" on path: DexPathList[[zip file \"/disk2/dalvik-dev/out/host/linux-x86/framework/GCBench.jar\"],nativeLibraryDirectories\u003d[/disk2/dalvik-dev/out/host/linux-x86/lib]]\n at dalvik.system.BaseDexClassLoader.findClass(BaseDexClassLoader.java:56)\n at java.lang.ClassLoader.loadClass(ClassLoader.java:511)\n at java.lang.ClassLoader.loadClass(ClassLoader.java:469)\n Suppressed: java.lang.ClassNotFoundException: GCBench\n at java.lang.Class.classForName(Native Method)\n at java.lang.BootClassLoader.findClass(ClassLoader.java:781)\n at java.lang.BootClassLoader.loadClass(ClassLoader.java:841)\n at java.lang.ClassLoader.loadClass(ClassLoader.java:504)\n ... 1 more\n Caused by: java.lang.NoClassDefFoundError: Class \"LGCBench;\" not found\n ... 5 more\nAnd after is:\njava.lang.ClassNotFoundException: Didn\u0027t find class \"GCBench\" on path: DexPathList[[zip file \"/disk2/dalvik-dev/out/host/linux-x86/framework/GCBench.jar\"],nativeLibraryDirectories\u003d[/disk2/dalvik-dev/out/host/linux-x86/lib]]\n at dalvik.system.BaseDexClassLoader.findClass(BaseDexClassLoader.java:56)\n at java.lang.ClassLoader.loadClass(ClassLoader.java:511)\n at java.lang.ClassLoader.loadClass(ClassLoader.java:469)\n Suppressed: java.io.IOException: Zip archive \u0027/disk2/dalvik-dev/out/host/linux-x86/framework/GCBench.jar\u0027 doesn\u0027t contain classes.dex\n at dalvik.system.DexFile.openDexFile(Native Method)\n at dalvik.system.DexFile.\u003cinit\u003e(DexFile.java:80)\n at dalvik.system.DexFile.\u003cinit\u003e(DexFile.java:59)\n at dalvik.system.DexPathList.loadDexFile(DexPathList.java:268)\n at dalvik.system.DexPathList.makeDexElements(DexPathList.java:235)\n at dalvik.system.DexPathList.\u003cinit\u003e(DexPathList.java:113)\n at dalvik.system.BaseDexClassLoader.\u003cinit\u003e(BaseDexClassLoader.java:48)\n at dalvik.system.PathClassLoader.\u003cinit\u003e(PathClassLoader.java:38)\n at java.lang.ClassLoader.createSystemClassLoader(ClassLoader.java:128)\n at java.lang.ClassLoader.access$000(ClassLoader.java:65)\n at java.lang.ClassLoader$SystemClassLoader.\u003cclinit\u003e(ClassLoader.java:81)\n at java.lang.ClassLoader.getSystemClassLoader(ClassLoader.java:137)\n Suppressed: java.lang.ClassNotFoundException: GCBench\n at java.lang.Class.classForName(Native Method)\n at java.lang.BootClassLoader.findClass(ClassLoader.java:781)\n at java.lang.BootClassLoader.loadClass(ClassLoader.java:841)\n at java.lang.ClassLoader.loadClass(ClassLoader.java:504)\n ... 1 more\n Caused by: java.lang.NoClassDefFoundError: Class \"LGCBench;\" not found\n ... 5 more\n\nAlso, move dex file verifier messages out of logs.\nIn the process the ClassLinker::dex_lock_ needed tidying to cover a smaller\nscope.

Since it can be read-only protected, the DEX-to-DEX compiler\nmust be able to temporarily change its protection to read-write mmapped file.\nTo achieve this, this CL adds support for changing DEX file protection with\nDexFile::EnableWrite and DexFile::DisableWrite methods. Besides, it also adds\na dedicated lock (DexFile::modification_lock) to ensure thread-safety and avoid\nconcurrent DEX file protection change (from a parallel DEX-to-DEX compiler on\nthe same DEX file).\n\nChange-Id: Iaafd103b9766810d7fc94a2c424a8fafba66e26a\n" }, { "commit": "f8adc60455b90c95a6a3c8f87830e4e88b2644e1", "tree": "da454c5488560a4abca669598ed2f29a22930e57", "parents": [ "dbbc99d2a197592aee8fdaf01253e426c9dff1d8" ], "author": { "name": "Ian Rogers", "email": "irogers@google.com", "time": "Thu Apr 18 17:06:19 2013 -0700" }, "committer": { "name": "Ian Rogers", "email": "irogers@google.com", "time": "Thu Apr 18 17:27:31 2013 -0700" }, "message": "Mem map bug fix and documentation.\n\nAddresses issue where valgrind treats a non-null \u0027addr\u0027 as meaning MAP_FIXED.\n\nChange-Id: Ibfd2360cd5bd226f9699022e07b918db612c2f7c\n" }, { "commit": "a40307e8562c20d9b9ce46e773864d07d95512a1", "tree": "ed4e85f5a7cd52458326a8dcb6ad4f89efa9131b", "parents": [ "5fe2c162a422426687ba3570df1dc68864386764" ], "author": { "name": "Ian Rogers", "email": "irogers@google.com", "time": "Fri Feb 22 11:32:44 2013 -0800" }, "committer": { "name": "Ian Rogers", "email": "irogers@google.com", "time": "Fri Feb 22 23:26:22 2013 -0800" }, "message": "Ensure VM\u0027s heap is accounted correctly.\n\nThe meminfo dumping assumes that dalvik heap is created using ashmem and has a\nprefix of \"dalvik-\".
