      "message": "mm: fix PageUptodate data race\n\nAfter running SetPageUptodate, preceeding stores to the page contents to\nactually bring it uptodate may not be ordered with the store to set the\npage uptodate.\n\nTherefore, another CPU which checks PageUptodate is true, then reads the\npage contents can get stale data.\n\nFix this by having an smp_wmb before SetPageUptodate, and smp_rmb after\nPageUptodate.\n\nMany places that test PageUptodate, do so with the page locked, and this\nwould be enough to ensure memory ordering in those places if\nSetPageUptodate were only called while the page is locked.  Unfortunately\nthat is not always the case for some filesystems, but it could be an idea\nfor the future.\n\nAlso bring the handling of anonymous page uptodateness in line with that of\nfile backed page management, by marking anon pages as uptodate when they\n_are_ uptodate, rather than when our implementation requires that they be\nmarked as such.  Doing allows us to get rid of the smp_wmb\u0027s in the page\ncopying functions, which were especially added for anonymous pages for an\nanalogous memory ordering problem.  Both file and anonymous pages are\nhandled with the same barriers.\n\nFAQ:\nQ. Why not do this in flush_dcache_page?\nA. Firstly, flush_dcache_page handles only one side (the smb side) of the\nordering protocol; we\u0027d still need smp_rmb somewhere. Secondly, hiding away\nmemory barriers in a completely unrelated function is nasty; at least in the\nPageUptodate macros, they are located together with (half) the operations\ninvolved in the ordering. Thirdly, the smp_wmb is only required when first\nbringing the page uptodate, wheras flush_dcache_page should be called each time\nit is written to through the kernel mapping. It is logically the wrong place to\nput it.\n\nQ. Why does this increase my text size / reduce my performance / etc.\nA. Because it is adding the necessary instructions to eliminate the data-race.\n\nQ. Can it be improved?\nA. Yes, eg. if you were to create a rule that all SetPageUptodate operations\nrun under the page lock, we could avoid the smp_rmb places where PageUptodate\nis queried under the page lock. Requires audit of all filesystems and at least\nsome would need reworking.

It takes the position where to\n        start and end the zeroing which avoids length calculations and\n\tmakes code clearer.\n\nzero_user_segment(page, start, end)\n\n        Same for a single segment.\n\nzero_user(page, start, length)\n\n        Length variant for the case where we know the length.\n\nWe remove the zero_user_page macro. Issues:\n\n1. Its a macro. Inline functions are preferable.\n\n2. The KM_USER0 macro is only defined for HIGHMEM.\n\n   Having to treat this special case everywhere makes the\n   code needlessly complex. The parameter for zeroing is always\n   KM_USER0 except in one single case that we open code.\n\nAvoiding KM_USER0 makes a lot of code not having to be dealing\nwith the special casing for HIGHMEM anymore. Dealing with\nkmap is only necessary for HIGHMEM configurations. In those\nconfigurations we use KM_USER0 like we do for a series of other\nfunctions defined in highmem.h.\n\nSince KM_USER0 is depends on HIGHMEM the existing zero_user_page\nfunction could not be a macro. zero_user_* functions introduced\nhere can be be inline because that constant is not used when these\nfunctions are called.\n\nAlso extract the flushing of the caches to be outside of the kmap.\n\n[akpm@linux-foundation.org: fix nfs and ntfs build]\n[akpm@linux-foundation.org: fix ntfs build some more]\nSigned-off-by: Christoph Lameter \u003cclameter@sgi.com\u003e\nCc: Steven French \u003csfrench@us.ibm.com\u003e\nCc: Michael Halcrow \u003cmhalcrow@us.ibm.com\u003e\nCc: \u003clinux-ext4@vger.kernel.org\u003e\nCc: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\nCc: Trond Myklebust \u003ctrond.myklebust@fys.uio.no\u003e\nCc: \"J.

      "message": "Add __GFP_MOVABLE for callers to flag allocations from high memory that may be migrated\n\nIt is often known at allocation time whether a page may be migrated or not.\nThis patch adds a flag called __GFP_MOVABLE and a new mask called\nGFP_HIGH_MOVABLE.  Allocations using the __GFP_MOVABLE can be either migrated\nusing the page migration mechanism or reclaimed by syncing with backing\nstorage and discarding.\n\nAn API function very similar to alloc_zeroed_user_highpage() is added for\n__GFP_MOVABLE allocations called alloc_zeroed_user_highpage_movable().  The\nflags used by alloc_zeroed_user_highpage() are not changed because it would\nchange the semantics of an existing API.  After this patch is applied there\nare no in-kernel users of alloc_zeroed_user_highpage() so it probably should\nbe marked deprecated if this patch is merged.\n\nNote that this patch includes a minor cleanup to the use of __GFP_ZERO in\nshmem.c to keep all flag modifications to inode-\u003emapping in the\nshmem_dir_alloc() helper function.

      "message": "[PATCH] Fix COW D-cache aliasing on fork\n\nProblem:\n\n1. There is a process containing two thread (T1 and T2).  The\n   thread T1 calls fork().  Then dup_mmap() function called on T1 context.\n\nstatic inline int dup_mmap(struct mm_struct *mm, struct mm_struct *oldmm)\n\t...\n\tflush_cache_mm(current-\u003emm);\n\t...\t/* A */\n\t(write-protect all Copy-On-Write pages)\n\t...\t/* B */\n\tflush_tlb_mm(current-\u003emm);\n\t...\n\n2. When preemption happens between A and B (or on SMP kernel), the\n   thread T2 can run and modify data on COW pages without page fault\n   (modified data will stay in cache).\n\n3. Some time after fork() completed, the thread T2 may cause a page\n   fault by write-protect on a COW page.\n\n4. Then data of the COW page will be copied to newly allocated\n   physical page (copy_cow_page()).  It reads data via kernel mapping.\n   The kernel mapping can have different \u0027color\u0027 with user space\n   mapping of the thread T2 (dcache aliasing).  Therefore\n   copy_cow_page() will copy stale data.  Then the modified data in\n   cache will be lost.\n\nIn order to allow architecture code to deal with this problem allow\narchitecture code to override copy_user_highpage() by defining\n__HAVE_ARCH_COPY_USER_HIGHPAGE in \u003casm/page.h\u003e.\n\nThe main part of this patch was originally written by Ralf Baechle;\nAtushi Nemoto did the the debugging.\n\nSigned-off-by: Atsushi Nemoto \u003canemo@mba.ocn.ne.jp\u003e\nSigned-off-by: Ralf Baechle \u003cralf@linux-mips.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"
