To make matters worse, it pads a short result with\nzeroes, which is a performance disaster if you have big buffers.\n\nstrlcpy(), by contrast, is a mis-designed \"fix\" for strlcpy(), lacking\nthe insane NUL padding, but having a differently broken return value\nwhich returns the original length of the source string. Which means\nthat it will read characters past the count from the source buffer, and\nyou have to trust the source to be properly terminated. It also makes\nerror handling fragile, since the test for overflow is unnecessarily\nsubtle.\n\nstrscpy() avoids both these problems, guaranteeing the NUL termination\n(but not excessive padding) if the destination size wasn\u0027t zero, and\nmaking the overflow condition very obvious by returning -E2BIG. It also\ndoesn\u0027t read past the size of the source, and can thus be used for\nuntrusted source data too.\n\nSo why did I waffle about this for so long?\n\nEvery time we introduce a new-and-improved interface, people start doing\nthese interminable series of trivial conversion patches.\n\nAnd every time that happens, somebody does some silly mistake, and the\nconversion patch to the improved interface actually makes things worse.\nBecause the patch is mindnumbing and trivial, nobody has the attention\nspan to look at it carefully, and it\u0027s usually done over large swatches\nof source code which means that not every conversion gets tested.\n\nSo I\u0027m pulling the strscpy() support because it *is* a better interface.\nBut I will refuse to pull mindless conversion patches. Use this in\nplaces where it makes sense, but don\u0027t do trivial patches to fix things\nthat aren\u0027t actually known to be broken.\n\n* \u0027strscpy\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/cmetcalf/linux-tile:\n tile: use global strscpy() rather than private copy\n string: provide strscpy()\n Make asm/word-at-a-time.h available on all architectures\n" }, { "commit": "15ecf9a986e2678f5de36ead23b89235612fc03f", "tree": "2eb463a995f42091a147a5093e1d3b818b78206e", "parents": [ "0d8770815f70cf41b69a82ede272b026dbb2df7d", "da6fb7a9e5bd6f04f7e15070f630bdf1ea502841" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sun Oct 04 11:47:28 2015 +0100" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sun Oct 04 11:47:28 2015 +0100" }, "message": "Merge tag \u0027md/4.3-fixes\u0027 of git://neil.brown.name/md\n\nPull md fixes from Neil Brown:\n \"Assorted fixes for md in 4.3-rc.\n\n Two tagged for -stable, and one is really a cleanup to match and\n improve kmemcache interface.\n\n* tag \u0027md/4.3-fixes\u0027 of git://neil.brown.name/md:\n md/bitmap: don\u0027t pass -1 to bitmap_storage_alloc.\n md/raid1: Avoid raid1 resync getting stuck\n md: drop null test before destroy functions\n md: clear CHANGE_PENDING in readonly array\n md/raid0: apply base queue limits *before* disk_stack_limits\n md/raid5: don\u0027t index beyond end of array in need_this_block().\n raid5: update analysis state for failed stripe\n md: wait for pending superblock updates before switching to read-only\n" }, { "commit": "0d8770815f70cf41b69a82ede272b026dbb2df7d", "tree": "3f088af1c614fd3b73e3aeae64223088797ef873", "parents": [ "3e519dde1e8a73e59b0eab52575a14a2986283b6", "d218af78492a36a4ae607c08fedfb59258440314" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sun Oct 04 11:41:58 2015 +0100" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sun Oct 04 11:41:58 2015 +0100" }, "message": "Merge branch \u0027upstream\u0027 of git://git.linux-mips.org/pub/scm/ralf/upstream-linus\n\nPull MIPS updates from Ralf Baechle:\n \"This week\u0027s round of MIPS fixes:\n - Fix JZ4740 build\n - Fix fallback to GFP_DMA\n - FP seccomp in case of ENOSYS\n - Fix bootmem panic\n - A number of FP and CPS fixes\n - Wire up new syscalls\n - Make sure BPF assembler objects can properly be disassembled\n - Fix BPF assembler code for MIPS I\"\n\n* \u0027upstream\u0027 of git://git.linux-mips.org/pub/scm/ralf/upstream-linus:\n MIPS: scall: Always run the seccomp syscall filters\n MIPS: Octeon: Fix kernel panic on startup from memory corruption\n MIPS: Fix R2300 FP context switch handling\n MIPS: Fix octeon FP context switch handling\n MIPS: BPF: Fix load delay slots.\n MIPS: BPF: Do all exports of symbols with FEXPORT().\n MIPS: Fix the build on jz4740 after removing the custom gpio.h\n MIPS: CPS: #ifdef on CONFIG_MIPS_MT_SMP rather than CONFIG_MIPS_MT\n MIPS: CPS: Don\u0027t include MT code in non-MT kernels.\n MIPS: CPS: Stop dangling delay slot from has_mt.\n MIPS: dma-default: Fix 32-bit fall back to GFP_DMA\n MIPS: Wire up userfaultfd and membarrier syscalls.\n" }, { "commit": "3e519dde1e8a73e59b0eab52575a14a2986283b6", "tree": "16e19515f19a239aaa155e927a37d8e59304b202", "parents": [ "2cf30826bbc6c940568be07e8fab0aee02165cf8", "791c76d58465a248cbd1ee422c8075cb90fa615f" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sun Oct 04 11:40:09 2015 +0100" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sun Oct 04 11:40:09 2015 +0100" }, "message": "Merge branch \u0027irq-urgent-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip\n\nPull irq fixes from Thomas Gleixner:\n \"This update contains:\n\n - Fix for a long standing race affecting /proc/irq/NNN\n\n - One line fix for ARM GICV3-ITS counting the wrong data\n\n - Warning silencing in ARM GICV3-ITS.

That\u0027s because the\nwalk_system_ram_range() filters out small memory regions that\nreside in the same page, but walk_system_ram_res() does not.\n\nHere\u0027s how I found the bug:\n\nAfter tracing prepare_elf64_headers() and prepare_elf64_ram_headers_callback(),\nthe code uses walk_system_ram_res() to fill-in crash memory regions information\nto the program header, so it counts those small memory regions that\nreside in a page area.\n\nBut, when the kernel was using walk_system_ram_range() in\nfill_up_crash_elf_data() to count the number of crash memory regions,\nit filters out small regions.\n\nI printed those small memory regions, for example:\n\n kexec: Get nr_ram ranges. vaddr\u003d0xffff880077592258 paddr\u003d0x77592258, sz\u003d0xdc0\n\nBased on the code in walk_system_ram_range(), this memory region\nwill be filtered out:\n\n pfn \u003d (0x77592258 + 0x1000 - 1) \u003e\u003e 12 \u003d 0x77593\n end_pfn \u003d (0x77592258 + 0xfc0 -1 + 1) \u003e\u003e 12 \u003d 0x77593\n end_pfn - pfn \u003d 0x77593 - 0x77593 \u003d 0 \u003c\u003d\u003d\u003d if (end_pfn \u003e pfn) is FALSE\n\nSo, the max_nr_ranges that\u0027s counted by the kernel doesn\u0027t include\nsmall memory regions - causing us to under-allocate the required space.\nThat causes the page fault crash that happens in a later code path\nwhen preparing ELF headers.\n\nThis bug is not easy to reproduce on small machines that have few\nCPUs, because the allocated page aligned ELF buffer has more free\nspace to cover those small memory regions\u0027 PT_LOAD headers.\n\nSigned-off-by: Lee, Chun-Yi \u003cjlee@suse.com\u003e\nCc: Andy Lutomirski \u003cluto@kernel.org\u003e\nCc: Baoquan He \u003cbhe@redhat.com\u003e\nCc: Jiang Liu \u003cjiang.liu@linux.intel.com\u003e\nCc: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\nCc: Mike Galbraith \u003cefault@gmx.de\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: Stephen Rothwell \u003csfr@canb.auug.org.au\u003e\nCc: Takashi Iwai \u003ctiwai@suse.de\u003e\nCc: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: Viresh Kumar \u003cviresh.kumar@linaro.org\u003e\nCc: Vivek Goyal \u003cvgoyal@redhat.com\u003e\nCc: kexec@lists.infradead.org\nCc: linux-kernel@vger.kernel.org\nCc: \u003cstable@vger.kernel.org\u003e\nLink: http://lkml.kernel.org/r/1443531537-29436-1-git-send-email-jlee@suse.com\nSigned-off-by: Ingo Molnar \u003cmingo@kernel.org\u003e\n" }, { "commit": "ccf03d6995fa4b784f5b987726ba98f4859bf326", "tree": "6fdc0aabe330fac0ec6ddc9d1cbf54b0a000ae3b", "parents": [ "274d83524895fe41ca8debae4eec60ede7252bb5" ], "author": { "name": "Dave Airlie", "email": "airlied@redhat.com", "time": "Thu Oct 01 16:28:25 2015 +1000" }, "committer": { "name": "Dave Airlie", "email": "airlied@redhat.com", "time": "Fri Oct 02 15:34:42 2015 +1000" }, "message": "drm/dp/mst: add some defines for logical/physical ports\n\nThis just removes the magic number.\n\nAcked-by: Daniel Vetter \u003cdaniel.vetter@ffwll.ch\u003e\nSigned-off-by: Dave Airlie \u003cairlied@redhat.com\u003e\n" }, { "commit": "274d83524895fe41ca8debae4eec60ede7252bb5", "tree": "343a2a9e9cba7f74ac5446047d09c05c5055da0e", "parents": [ "d9515c5ec1a20c77d83471e634ad9bb12deb0eac" ], "author": { "name": "Dave Airlie", "email": "airlied@redhat.com", "time": "Wed Sep 30 10:39:42 2015 +1000" }, "committer": { "name": "Dave Airlie", "email": "airlied@redhat.com", "time": "Fri Oct 02 15:34:42 2015 +1000" }, "message": "drm/dp/mst: drop cancel work sync in the mstb destroy path (v2)\n\nSince 9eb1e57f564d4e6e10991402726cc83fe0b9172f\ndrm/dp/mst: make sure mst_primary mstb is valid in work function\n\nwe validate the mstb structs in the work function, and doing\nthat takes a reference.

configured in a\n different way and may cause an interrupt storm to happen as a\n result with an extra ACPI SCI IRQ handling simplification on top of\n it (Jiang Liu).\n\n - Update of the PCI power management documentation that became\n outdated and started to actively confuse the readers to make it\n actually reflect the code (Rafael J Wysocki).\n\n - turbostat fixes including an IVB Xeon regression fix (related to\n the --debug command line option), Skylake adjustment for the TSC\n running at a frequency that doesn\u0027t match the base one exactly, and\n a Knights Landing quirk to account for the fact that it only\n updates APERF and MPERF every 1024 clock cycles plus bumping up the\n turbostat version number (Len Brown, Hubert Chrzaniuk)\"\n\n* tag \u0027pm+acpi-4.3-rc4\u0027

This is because pmd_modify calls pte_modify which is now\nallowed to modify the type of the page table entry.\n\nThis patch reverts commit 6910fa16dbe142f6a0fd0fd7c249f9883ff7fc8a, and\nfixes the problem it was trying to address by adjusting PAGE_NONE to\nrepresent a table entry.
