"[PATCH] SELinux: add security hook call to mediate attach_task (kernel/cpuset.c)\n\nAdd a security hook call to enable security modules to control the ability\nto attach a task to a cpuset. While limited control over this operation is\npossible via permission checks on the pseudo fs interface, those checks are\nnot sufficient to control access to the target task, which is looked up in\nthis function. The existing task_setscheduler hook is re-used for this\noperation since this falls under the same class of operations.\n\nSigned-off-by: David Quigley \u003cdpquigl@tycho.nsa.gov\u003e\nAcked-by: Stephen Smalley \u003csds@tycho.nsa.gov\u003e\nSigned-off-by: James Morris \u003cjmorris@namei.org\u003e\nAcked-by: Paul Jackson \u003cpj@sgi.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "e7834f8fccd791225a1cf91c2c3e740ad8e2e145", "tree": "8f48d03d7b1dc32d326825fef1d1c54117a06ac8", "parents": [ "03e68060636e05989ea94bcb671ab633948f328c" ], "author": { "name": "David Quigley", "email": "dpquigl@tycho.nsa.gov", "time": "Fri Jun 23 02:03:59 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Jun 23 07:42:53 2006 -0700" }, "message": "[PATCH] SELinux: add security hooks to {get,set}affinity\n\nThis patch adds LSM hooks into the setaffinity and getaffinity functions to\nenable security modules to control these operations between tasks with\ntask_setscheduler and task_getscheduler LSM hooks.\n\nSigned-off-by: David Quigley \u003cdpquigl@tycho.nsa.gov\u003e\nAcked-by: Stephen Smalley \u003csds@tycho.nsa.gov\u003e\nSigned-off-by: James Morris \u003cjmorris@namei.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "03e68060636e05989ea94bcb671ab633948f328c", "tree": "aee5e7b55f31998536dd3a4f54f38caeee6105d6", "parents": [ "9216dfad4fc97ab639ef0885efc713f3d7a20d5b" ], "author": { "name": "James Morris", "email": "jmorris@namei.org", "time": "Fri Jun 23 02:03:58 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Jun 23 07:42:53 2006 -0700" }, "message": "[PATCH] lsm: add task_setioprio hook\n\nImplement an LSM hook for setting a task\u0027s IO priority, similar to the hook\nfor setting a tasks\u0027s nice value.\n\nA previous version of this LSM hook was included in an older version of\nmultiadm by Jan Engelhardt, although I don\u0027t recall it being submitted\nupstream.\n\nAlso included is the corresponding SELinux hook, which re-uses the setsched\npermission in the proccess class.\n\nSigned-off-by: James Morris \u003cjmorris@namei.org\u003e\nAcked-by: Stephen Smalley \u003csds@tycho.nsa.gov\u003e\nCc: Jan Engelhardt \u003cjengelh@linux01.gwdg.de\u003e\nCc: Chris Wright \u003cchrisw@sous-sol.org\u003e\nCc: Jens Axboe \u003caxboe@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "9216dfad4fc97ab639ef0885efc713f3d7a20d5b", "tree": "546e301f3181f56133509327f9c5ed035dd4b50d", "parents": [ "1b2db9fb7adc4d67d9ce7d16ce79c41ee84730fe" ], "author": { "name": "Christoph Lameter", "email": "clameter@sgi.com", "time": "Fri Jun 23 02:03:57 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Jun 23 07:42:53 2006 -0700" }, "message": "[PATCH] move_pages: fix 32 -\u003e 64 bit compat function\n\nThe definition of the third parameter is a pointer to an array of virtual\naddresses which give us some trouble.

(If the process were later to fault on this\n orphaned entry, it would hit the same BUG from migration_entry_wait.)\n\n This could be fixed by locking anon_vma in copy_one_pte, but we\u0027d rather\n not. There\u0027s no such problem with file pages, because vma_prio_tree_add\n adds child vma after parent vma, and the page table locking at each end is\n enough to serialize. Follow that example with anon_vma: add new vmas to the\n tail instead of the head.\n\n (There\u0027s no corresponding problem when inserting migration entries,\n because a missed pte will leave the page count and mapcount high, which is\n allowed for. And there\u0027s no corresponding problem when migrating via swap,\n because a leftover swap entry will be correctly faulted.
