This has a side effect of forcing the operand\nsize to 8 bytes on 64-bit hosts.\n\nNow, a 32-bit guest goes and fork()s a process. It write protects a stack\npage at 0xbffff000 using the \u0027btr\u0027 instruction, at offset 0xffc in the page\ntable, with bit offset 1 (for the write permission bit).\n\nThe emulator now forces the operand size to 8 bytes as previously described,\nand an innocent page table update turns into a cross-page-boundary write,\nwhich is assumed by the mmu code not to be a page table, so it doesn\u0027t\nactually clear the corresponding shadow page table entry. The guest and\nhost permissions are out of sync and guest memory is corrupted soon\nafterwards, leading to guest failure.\n\nFix by not using BITS_PER_LONG as the word size; instead use the actual\noperand size, so we get a 32-bit write in that case.\n\nNote we still have to teach the mmu to handle cross-page-boundary writes\nto guest page table; but for now this allows Damn Small Linux 0.4 (2.4.20)\nto boot.\n\nSigned-off-by: Avi Kivity \u003cavi@qumranet.com\u003e\n" }, { "commit": "afeb1f14c5478560262b37431726eb0eb1a42e9e", "tree": "ff5613b598ab4e0dcf13426e453c6bcf6075e03e", "parents": [ "36868f7b0efd0b6a1d45fe3b40a6c4bc63222659" ], "author": { "name": "Avi Kivity", "email": "avi@qumranet.com", "time": "Tue Mar 27 17:50:20 2007 +0200" }, "committer": { "name": "Avi Kivity", "email": "avi@qumranet.com", "time": "Thu May 03 10:52:27 2007 +0300" }, "message": "KVM: Remove debug message\n\nNo longer interesting.\n\nSigned-off-by: Avi Kivity \u003cavi@qumranet.com\u003e\n" }, { "commit": "36868f7b0efd0b6a1d45fe3b40a6c4bc63222659", "tree": "79acd363a5fce690443f438dcba33b1d88e03373", "parents": [ "55bf4028342d96b21fe5dc0721b481b0bc1e81f6" ], "author": { "name": "Avi Kivity", "email": "avi@qumranet.com", "time": "Mon Mar 26 19:31:52 2007 +0200" }, "committer": { "name": "Avi Kivity", "email": "avi@qumranet.com", "time": "Thu May 03 10:52:27 2007 +0300" }, "message": "KVM: Use list_move()\n\nUse list_move() where possible.
