Currently it does add an \u0027unlabeled\u0027\nlabel in this case, which we\u0027ve found causes problems later.\n\nSELinux always maintains a safe internal label if there is none, so with this\npatch, we just stick with that and wait until a policy is loaded before adding\na persistent label on disk.\n\nThe effect is simply that if you boot with SELinux enabled but no policy\nloaded and create a file in that state, SELinux won\u0027t try to set a security\nextended attribute on the new inode on the disk. This is the only sane\nbehavior for SELinux in that state, as it cannot determine the right label to\nassign in the absence of a policy. That state usually doesn\u0027t occur, but the\nrawhide installer seemed to be misbehaving temporarily so it happened to show\nup on a test install.\n\nSigned-off-by: Stephen Smalley \u003csds@tycho.nsa.gov\u003e\nAcked-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": "b20a35035f983f4ac7e29c4a68f30e43510007e0", "tree": "fdf090ddddbcc275349f62f71adc98649e2c683b", "parents": [ "442295c94bf650221af3ef20fc68fa3e93876818" ], "author": { "name": "Christoph Lameter", "email": "clameter@sgi.com", "time": "Wed Mar 22 00:09:12 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Wed Mar 22 07:54:06 2006 -0800" }, "message": "[PATCH] page migration reorg\n\nCentralize the page migration functions in anticipation of additional\ntinkering.

However, the test it uses\nto do so is incorrect: it calls is_hugepage_only_range on a hugepage sized\nrange at the start of the vma. is_hugepage_only_range() will return true\nif the given range has any intersection with a hugepage address region, and\nin this case the given region need not be hugepage aligned. So, for\nexample, this test can return true if called on, say, a 4k VMA immediately\npreceding a (nicely aligned) hugepage VMA.\n\nAt present we get away with this because the powerpc version of\nhugetlb_free_pgd_range() is just a call to free_pgd_range().

There\u0027s a\nsomewhat dubious (and racy) heuristic when making a new mmap() to check if\nthere are enough available hugepages to fully satisfy that mapping.\n\nA particularly obvious case where the heuristic breaks down is where a\nprocess maps its hugepages not as a single chunk, but as a bunch of\nindividually mmap()ed (or shmat()ed) blocks without touching and\ninstantiating the pages in between allocations. In this case the size of\neach block is compared against the total number of available hugepages.\nIt\u0027s thus easy for the process to become overcommitted, because each block\nmapping will succeed, although the total number of hugepages required by\nall blocks exceeds the number available. In particular, this defeats such\na program which will detect a mapping failure and adjust its hugepage usage\ndownward accordingly.\n\nThe patch below addresses this problem, by strictly reserving a number of\nphysical hugepages for hugepage inodes which have been mapped, but not\ninstatiated. MAP_SHARED mappings are thus \"safe\" - they will fail on\nmmap(), not later with an OOM SIGKILL. MAP_PRIVATE mappings can still\ntrigger an OOM. (Actually SHARED mappings can technically still OOM, but\nonly if the sysadmin explicitly reduces the hugepage pool between mapping\nand instantiation)\n\nThis patch appears to address the problem at hand - it allows DB2 to start\ncorrectly, for instance, which previously suffered the failure described\nabove.\n\nThis patch causes no regressions on the libhugetblfs testsuite, and makes a\ntest (designed to catch this problem) pass which previously failed (ppc64,\nPOWER5).\n\nSigned-off-by: David Gibson \u003cdwg@au1.ibm.com\u003e\nCc: William Lee Irwin III \u003cwli@holomorphy.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "3935baa9bcda3ccaee4f7849f5157d316e34412e", "tree": "45f6d064693a91171c57159acac43822cae6e129", "parents": [ "79ac6ba40eb8d70f0d204e98ae9b63280ad1018c" ], "author": { "name": "David Gibson", "email": "david@gibson.dropbear.id.au", "time": "Wed Mar 22 00:08:53 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Wed Mar 22 07:54:03 2006 -0800" }, "message": "[PATCH] hugepage: serialize hugepage allocation and instantiation\n\nCurrently, no lock or mutex is held between allocating a hugepage and\ninserting it into the pagetables / page cache. When we do go to insert the\npage into pagetables or page cache, we recheck and may free the newly\nallocated hugepage. However, since the number of hugepages in the system\nis strictly limited, and it\u0027s usualy to want to use all of them, this can\nstill lead to spurious allocation failures.\n\nFor example, suppose two processes are both mapping (MAP_SHARED) the same\nhugepage file, large enough to consume the entire available hugepage pool.\nIf they race instantiating the last page in the mapping, they will both\nattempt to allocate the last available hugepage. One will fail, of course,\nreturning OOM from the fault and thus causing the process to be killed,\ndespite the fact that the entire mapping can, in fact, be instantiated.\n\nThe patch fixes this race by the simple method of adding a (sleeping) mutex\nto serialize the hugepage fault path between allocation and insertion into\npagetables and/or page cache. It would be possible to avoid the\nserialization by catching the allocation failures, waiting on some\ncondition, then rechecking to see if someone else has instantiated the page\nfor us. Given the likely frequency of hugepage instantiations, it seems\nvery doubtful it\u0027s worth the extra complexity.\n\nThis patch causes no regression on the libhugetlbfs testsuite, and one\ntest, which can trigger this race now passes where it previously failed.\n\nActually, the test still sometimes fails, though less often and only as a\nshmat() failure, rather processes getting OOM killed by the VM. The dodgy\nheuristic tests in fs/hugetlbfs/inode.c for whether there\u0027s enough hugepage\nspace aren\u0027t protected by the new mutex, and would be ugly to do so, so\nthere\u0027s still a race there.
