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. However, we\ncan determine if a vma is in one these sections by checking it against\nthe gate_vma and checking for a non-NULL return value from\narch_vma_name(). Thus, freeing a valuable vma bit.\n\nSigned-off-by: Jason Baron \u003cjbaron@redhat.com\u003e\nAcked-by: Roland McGrath \u003croland@hack.frob.com\u003e\nCc: Chris Metcalf \u003ccmetcalf@tilera.com\u003e\nCc: Avi Kivity \u003cavi@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "5f293474c4c6c4dc2baaf2dfd486748b5986de76", "tree": "1ced9f5c401aa7d808954a21e527a0f0e54ea9b8", "parents": [ "91ec87d57fc38c529034e853687dfb7756de5406" ], "author": { "name": "Andy Lutomirski", "email": "luto@mit.edu", "time": "Thu Mar 22 21:15:52 2012 -0700" }, "committer": { "name": "John Stultz", "email": "john.stultz@linaro.org", "time": "Fri Mar 23 16:49:35 2012 -0700" }, "message": "x86-64: Inline vdso clock_gettime helpers\n\nThis is about a 3% speedup on Sandy Bridge.\n\nSigned-off-by: Andy Lutomirski \u003cluto@amacapital.net\u003e\nSigned-off-by: John Stultz \u003cjohn.stultz@linaro.org\u003e\n" }, { "commit": "91ec87d57fc38c529034e853687dfb7756de5406", "tree": "4f88d6a7e0221bdd791a1de6d4c36b17da8337a2", "parents": [ "88b28adf6fcdd6d10a1cfc7765bb200d7366a265" ], "author": { "name": "Andy Lutomirski", "email": "luto@mit.edu", "time": "Thu Mar 22 21:15:51 2012 -0700" }, "committer": { "name": "John Stultz", "email": "john.stultz@linaro.org", "time": "Fri Mar 23 16:49:33 2012 -0700" }, "message": "x86-64: Simplify and optimize vdso clock_gettime monotonic variants\n\nWe used to store the wall-to-monotonic offset and the realtime base.\nIt\u0027s faster to precompute the monotonic base.\n\nThis is about a 3% speedup on Sandy Bridge for CLOCK_MONOTONIC.\nIt\u0027s much more impressive for CLOCK_MONOTONIC_COARSE.\n\nSigned-off-by: Andy Lutomirski \u003cluto@amacapital.net\u003e\nSigned-off-by: John Stultz \u003cjohn.stultz@linaro.org\u003e\n" }, { "commit": "2ab516575f2f273b19d95140d02c54612201e80a", "tree": "26db92249e65754d99759af21fd207507a81cec8", "parents": [ "6c260d586343f7f78239d90aa9e2cfed02f74ff3" ], "author": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Tue Feb 28 19:46:04 2012 +0000" }, "committer": { "name": "John Stultz", "email": "john.stultz@linaro.org", "time": "Thu Mar 15 18:17:58 2012 -0700" }, "message": "x86: vdso: Use seqcount instead of seqlock\n\nThe update of the vdso data happens under xtime_lock, so adding a\nnested lock is pointless.

Prepare for\nthis change by updating users of gfp and slab facilities include those\nheaders directly instead of assuming availability. As this conversion\nneeds to touch large number of source files, the following script is\nused as the basis of conversion.\n\n http://userweb.kernel.org/~tj/misc/slabh-sweep.py\n\nThe script does the followings.\n\n* Scan files for gfp and slab usages and update includes such that\n only the necessary includes are there. ie. if only gfp is used,\n gfp.h, if slab is used, slab.h.\n\n* When the script inserts a new include, it looks at the include\n blocks and try to put the new include such that its order conforms\n to its surrounding. It\u0027s put in the include block which contains\n core kernel includes, in the same order that the rest are ordered -\n alphabetical, Christmas tree, rev-Xmas-tree or at the end if there\n doesn\u0027t seem to be any matching order.\n\n* If the script can\u0027t find a place to put a new include (mostly\n because the file doesn\u0027t have fitting include block), it prints out\n an error message indicating which .h file needs to be added to the\n file.\n\nThe conversion was done in the following steps.\n\n1. The initial automatic conversion of all .c files updated slightly\n over 4000 files, deleting around 700 includes and adding ~480 gfp.h\n and ~3000 slab.h inclusions. The script emitted errors for ~400\n files.\n\n2. Each error was manually checked. Some didn\u0027t need the inclusion,\n some needed manual addition while adding it to implementation .h or\n embedding .c file was more appropriate for others. This step added\n inclusions to around 150 files.\n\n3. The script was run again and the output was compared to the edits\n from #2 to make sure no file was left behind.\n\n4. Several build tests were done and a couple of problems were fixed.\n e.g. lib/decompress_*.c used malloc/free() wrappers around slab\n APIs requiring slab.h to be added manually.\n\n5. The script was run on all .h files but without automatically\n editing them as sprinkling gfp.h and slab.h inclusions around .h\n files could easily lead to inclusion dependency hell. Most gfp.h\n inclusion directives were ignored as stuff from gfp.h was usually\n wildly available and often used in preprocessor macros. Each\n slab.h inclusion directive was examined and added manually as\n necessary.\n\n6. percpu.h was updated not to include slab.h.\n\n7. Build test were done on the following configurations and failures\n were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my\n distributed build env didn\u0027t work with gcov compiles) and a few\n more options had to be turned off depending on archs to make things\n build (like ipr on powerpc/64 which failed due to missing writeq).\n\n * x86 and x86_64 UP and SMP allmodconfig and a custom test config.\n * powerpc and powerpc64 SMP allmodconfig\n * sparc and sparc64 SMP allmodconfig\n * ia64 SMP allmodconfig\n * s390 SMP allmodconfig\n * alpha SMP allmodconfig\n * um on x86_64 SMP allmodconfig\n\n8. percpu.h modifications were reverted so that it could be applied as\n a separate patch and serve as bisection point.\n\nGiven the fact that I had only a couple of failures from tests on step\n6, I\u0027m fairly confident about the coverage of this conversion patch.\nIf there is a breakage, it\u0027s likely to be something in one of the arch\nheaders which should be easily discoverable easily on most builds of\nthe specific arch.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nGuess-its-ok-by: Christoph Lameter \u003ccl@linux-foundation.org\u003e\nCc: Ingo Molnar \u003cmingo@redhat.com\u003e\nCc: Lee Schermerhorn \u003cLee.Schermerhorn@hp.com\u003e\n" }, { "commit": "24a065624dcdd91e8bfd0f14113feb91c7ed11ca", "tree": "cf4492df2caa95fa4d6a6730db2cdfe564ede55e", "parents": [ "a09b6e811800cba79e8104deff12c544b835a3ff" ], "author": { "name": "Eric W.

This is very fast as we don\u0027t\nhave to access any hardware (which can be very painful if you\u0027re using\nsomething like the acpi_pm clocksource), and we can even use the vdso\nclock_gettime() method to avoid the syscall.
