process state via\nproc from full ptrace access by renaming ptrace_may_attach to\nptrace_may_access and adding a mode argument indicating whether only\nread access or full attach access is requested. This allows security\nmodules to permit access to reading process state without granting\nfull ptrace access. The base DAC/capability checking remains unchanged.\n\nRead access to /proc/pid/mem continues to apply a full ptrace attach\ncheck since check_mem_permission() already requires the current task\nto already be ptracing the target. The other ptrace checks within\nproc for elements like environ, maps, and fds are changed to pass the\nread mode instead of attach.\n\nIn the SELinux case, we model such reading of process state as a\nreading of a proc file labeled with the target process\u0027 label. This\nenables SELinux policy to permit such reading of process state without\npermitting control or manipulation of the target process, as there are\na number of cases where programs probe for such information via proc\nbut do not need to be able to control the target (e.g. procps,\nlsof, PolicyKit, ConsoleKit). At present we have to choose between\nallowing full ptrace in policy (more permissive than required/desired)\nor breaking functionality (or in some cases just silencing the denials\nvia dontaudit rules but this can hide genuine attacks).\n\nThis version of the patch incorporates comments from Casey Schaufler\n(change/replace existing ptrace_may_attach interface, pass access\nmode), and Chris Wright (provide greater consistency in the checking).\n\nNote that like their predecessors __ptrace_may_attach and\nptrace_may_attach, the __ptrace_may_access and ptrace_may_access\ninterfaces use different return value conventions from each other (0\nor -errno vs. 1 or 0). I retained this difference to avoid any\nchanges to the caller logic but made the difference clearer by\nchanging the latter interface to return a bool rather than an int and\nby adding a comment about it to ptrace.h for any future callers.\n\nSigned-off-by: Stephen Smalley \u003csds@tycho.nsa.gov\u003e\nAcked-by: Chris Wright \u003cchrisw@sous-sol.org\u003e\nSigned-off-by: James Morris \u003cjmorris@namei.org\u003e\n" }, { "commit": "199a952876adbfc2b6c13b8b07adabebf4ff54b2", "tree": "8c53dca02da179c0a43735020c77e6df9d4c6117", "parents": [ "0c81b2a1448bc6a2a9b2d6469fb0669fb4b25e5b" ], "author": { "name": "Lai Jiangshan", "email": "laijs@cn.fujitsu.com", "time": "Thu Jun 26 10:06:43 2008 +0800" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Sun Jul 13 23:12:17 2008 +0200" }, "message": "rcu classic: update qlen when cpu offline\n\nWhen callbacks are moved from offline cpu to this cpu,\nthe qlen field of this rdp should be updated.\n\n[ Paul E.

This excludes those machines from high\nresolution timers / dynamic ticks, which hurts especially X2 based\nlaptops.\n\nThe current boot time C1E detection has another, more serious flaw\nas well: some BIOSes do not enable C1E until the ACPI processor module\nis loaded. This causes systems to stop working after that point.\n\nTo work nicely with C1E enabled machines we use a separate idle\nfunction, which checks on idle entry whether C1E was enabled in the\nInterrupt Pending Message MSR. This allows us to do timer broadcasting\nfor C1E and covers the late enablement of C1E as well.\n\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "d763d5edf945eec47bd443b699f174976f0afc13", "tree": "3e5cd46b9a783999716bf92176854f4f1215d930", "parents": [ "790e2a290b499b0400254e6870ec27969065d122", "1b40a895df6c7d5a80e71f65674060b03d84bbef" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Mon Jul 07 08:07:35 2008 +0200" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Mon Jul 07 08:07:35 2008 +0200" }, "message": "Merge branch \u0027linus\u0027 into tracing/mmiotrace\n" }, { "commit": "032f82786f9be4635acaa5f77feca175a4ac5fe1", "tree": "11ce43c1086d3dec43c92b0a2cc740240b338fb7", "parents": [ "46ac22bab42cc868b9c1d0e915ddbc8e8065a44d", "b7279469d66b55119784b8b9529c99c1955fe747" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Mon Jul 07 08:01:26 2008 +0200" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Mon Jul 07 08:01:26 2008 +0200" }, "message": "Merge commit \u0027v2.6.26-rc9\u0027 into sched/devel\n" }, { "commit": "84df87b7ebdcbbc0f59df9526f4e63fda70647d3", "tree": "e91ab6df3d2f6403e315bfedd9e02736d0e6f4a4", "parents": [ "537388bb6563bfde7c0307b95ecc1f7a1ae39b02", "3b7253238801a7b97b3929d8db2fa7a0721fb17b" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Jul 05 13:09:31 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Jul 05 13:09:31 2008 -0700" }, "message": "Merge branch \u0027core-fixes-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip\n\n* \u0027core-fixes-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip:\n softlockup: print a module list on being stuck\n" }, { "commit": "3b7253238801a7b97b3929d8db2fa7a0721fb17b", "tree": "6238744e76fbcaddd7cc2107845fbc112462640d", "parents": [ "8558f8f81680a43d383abd1b5f23d3501fedfa65" ], "author": { "name": "Arjan van de Ven", "email": "arjan@linux.intel.com", "time": "Mon Jun 16 15:51:08 2008 -0700" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Sat Jul 05 08:51:24 2008 +0200" }, "message": "softlockup: print a module list on being stuck\n\nMost places in the kernel that go BUG: print a module list\n(which is very useful for doing statistics and finding patterns),\nhowever the softlockup detector does not do this yet.\n\nThis patch adds the one line change to fix this gap.\n\nSigned-off-by: Arjan van de Ven \u003carjan@linux.intel.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "086f7316f0d400806d76323beefae996bb3849b1", "tree": "679405a89b7f8c7a75d3896e43c837b5a5115d7b", "parents": [ "abbaeff38c00cb7f6817ec1cef406b27081ebedd" ], "author": { "name": "Andrew G.
