Tracing also\nindicated that log recovery was also reading the block, but then\nnever writing it before log recovery invalidated the cache,\nindicating that it was not modified by log recovery.\n\nMore detailed analysis of the corpse indicated that the filesystem\nhad a uuid of \"a4131074-1872-4cac-9323-2229adbcb886\" but the XARM\nblock had a uuid of \"8f32f043-c3c9-e7f8-f947-4e7f989c05d3\", which\nindicated it was a block from an older filesystem. The reason that\nlog recovery didn\u0027t replay it was that the LSN in the XARM block was\nlarger than the LSN of the transaction being replayed, and so the\nblock was not overwritten by log recovery.\n\nHence, log recovery cant blindly trust the magic number and LSN in\nthe block - it must verify that it belongs to the filesystem being\nrecovered before using the LSN. i.e. if the UUIDs don\u0027t match, we\nneed to unconditionally recovery the change held in the log.\n\nThis patch was first tested on a block device that was repeatedly\ncausing xfs/182 to fail with the same failure on the same block with\nthe same directory read corruption signature (i.e. XARM block).

We have support where the first HSA_SIZE bytes are saved into\na hypervisor owned memory area (HSA) before the kdump kernel is booted.\nWhen the kdump kernel starts, it is restricted to use only HSA_SIZE bytes.\n\nThe advantages of this mechanism are:\n\n * No crashkernel memory has to be defined in the old kernel.\n * Early boot problems (before kexec_load has been done) can be dumped\n * Non-Linux systems can be dumped.\n\nWe modify the s390 copy_oldmem_page() function to read from the HSA memory\nif memory below HSA_SIZE bytes is requested.\n\nSince we cannot use the kexec tool to load the kernel in this scenario,\nwe have to build the ELF header in the 2nd (kdump/new) kernel.\n\nSo with the following patch set we would like to introduce the new\nfunction that the ELF header for /proc/vmcore can be created in the 2nd\nkernel memory.\n\nThe following steps are done during zfcpdump execution:\n\n1. Production system crashes\n2. User boots a SCSI disk that has been prepared with the zfcpdump tool\n3. Hypervisor saves CPU state of boot CPU and HSA_SIZE bytes of memory into HSA\n4. Boot loader loads kernel into low memory area\n5. Kernel boots and uses only HSA_SIZE bytes of memory\n6. Kernel saves registers of non-boot CPUs\n7. Kernel does memory detection for dump memory map\n8. Kernel creates ELF header for /proc/vmcore\n9. /proc/vmcore uses this header for initialization\n10. The zfcpdump user space reads /proc/vmcore to write dump to SCSI disk\n - copy_oldmem_page() copies from HSA for memory below HSA_SIZE\n - copy_oldmem_page() copies from real memory for memory above HSA_SIZE\n\nCurrently for s390 we create the ELF core header in the 2nd kernel with a\nsmall trick. We relocate the addresses in the ELF header in a way that\nfor the /proc/vmcore code it seems to be in the 1st kernel (old) memory\nand the read_from_oldmem() returns the correct data. This allows the\n/proc/vmcore code to use the ELF header in the 2nd kernel.\n\nThis patch:\n\nExchange the old mechanism with the new and much cleaner function call\noverride feature that now offcially allows to create the ELF core header\nin the 2nd kernel.\n\nTo use the new feature the following function have to be defined\nby the architecture backend code to read from new memory:\n\n * elfcorehdr_alloc: Allocate ELF header\n * elfcorehdr_free: Free the memory of the ELF header\n * elfcorehdr_read: Read from ELF header\n * elfcorehdr_read_notes: Read from ELF notes\n\nSigned-off-by: Michael Holzheu \u003cholzheu@linux.vnet.ibm.com\u003e\nAcked-by: Vivek Goyal \u003cvgoyal@redhat.com\u003e\nCc: HATAYAMA Daisuke \u003cd.hatayama@jp.fujitsu.com\u003e\nCc: Jan Willeke \u003cwilleke@de.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "6b3c538f5b2cfc53cb6803ec5001bbcf8f18a98e", "tree": "5a3dd78b655c93d7248facb2377be2630435b1fc", "parents": [ "4e0621a07ea58a0dc15859be3b743bdeb194a51b" ], "author": { "name": "Oleg Nesterov", "email": "oleg@redhat.com", "time": "Wed Sep 11 14:24:46 2013 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Sep 11 15:59:09 2013 -0700" }, "message": "exec: cleanup the error handling in search_binary_handler()\n\nThe error hanling and ret-from-loop look confusing and inconsistent.\n\n- \"retval \u003e\u003d 0\" simply returns\n\n- \"!bprm-\u003efile\" returns too but with read_unlock() because\n binfmt_lock was already re-acquired\n\n- \"retval !\u003d -ENOEXEC || bprm-\u003emm \u003d\u003d NULL\" does \"break\" and\n relies on the same check after the main loop\n\nConsolidate these checks into a single if/return statement.\n\nneed_retry still checks \"retval \u003d\u003d -ENOEXEC\", but this and -ENOENT before\nthe main loop are not needed.

For such filesystems balance_dirty_pages always check bdi\ncounters against bdi limits. I.e. even if global \"nr_dirty\" is under\n\"freerun\", it\u0027s not allowed to skip bdi checks. The only use case for now\nis fuse: it sets bdi max_ratio to 1% by default and system administrators\nare supposed to expect that this limit won\u0027t be exceeded.\n\nThe feature is on if a BDI is marked by BDI_CAP_STRICTLIMIT flag. A\nfilesystem may set the flag when it initializes its BDI.\n\nThe problematic scenario comes from the fact that nobody pays attention to\nthe NR_WRITEBACK_TEMP counter (i.e. number of pages under fuse\nwriteback). The implementation of fuse writeback releases original page\n(by calling end_page_writeback) almost immediately. A fuse request queued\nfor real processing bears a copy of original page. Hence, if userspace\nfuse daemon doesn\u0027t finalize write requests in timely manner, an\naggressive mmap writer can pollute virtually all memory by those temporary\nfuse page copies. They are carefully accounted in NR_WRITEBACK_TEMP, but\nnobody cares.\n\nTo make further explanations shorter, let me use \"NR_WRITEBACK_TEMP\nproblem\" as a shortcut for \"a possibility of uncontrolled grow of amount\nof RAM consumed by temporary pages allocated by kernel fuse to process\nwriteback\".\n\nThe problem was very easy to reproduce. There is a trivial example\nfilesystem implementation in fuse userspace distribution: fusexmp_fh.c. I\nadded \"sleep(1);\" to the write methods, then recompiled and mounted it.\nThen created a huge file on the mount point and run a simple program which\nmmap-ed the file to a memory region, then wrote a data to the region. An\nhour later I observed almost all RAM consumed by fuse writeback. Since\nthen some unrelated changes in kernel fuse made it more difficult to\nreproduce, but it is still possible now.\n\nPutting this theoretical happens-in-the-lab thing aside, there is another\nthing that really hurts real world (FUSE) users. This is write-through\npage cache policy FUSE currently uses. I.e. handling write(2), kernel\nfuse populates page cache and flushes user data to the server\nsynchronously. This is excessively suboptimal. Pavel Emelyanov\u0027s patches\n(\"writeback cache policy\") solve the problem, but they also make resolving\nNR_WRITEBACK_TEMP problem absolutely necessary. Otherwise, simply copying\na huge file to a fuse mount would result in memory starvation. Miklos,\nthe maintainer of FUSE, believes strictlimit feature the way to go.\n\nAnd eventually putting FUSE topics aside, there is one more use-case for\nstrictlimit feature. Using a slow USB stick (mass storage) in a machine\nwith huge amount of RAM installed is a well-known pain. Let\u0027s make simple\ncomputations. Assuming 64GB of RAM installed, existing implementation of\nbalance_dirty_pages will start throttling only after 9.6GB of RAM becomes\ndirty (freerun \u003d\u003d 15% of total RAM). So, the command \"cp 9GB_file\n/media/my-usb-storage/\" may return in a few seconds, but subsequent\n\"umount /media/my-usb-storage/\" will take more than two hours if effective\nthroughput of the storage is, to say, 1MB/sec.\n\nAfter inclusion of strictlimit feature, it will be trivial to add a knob\n(e.g. /sys/devices/virtual/bdi/x:y/strictlimit) to enable it on demand.\nManually or via udev rule. May be I\u0027m wrong, but it seems to be quite a\nnatural desire to limit the amount of dirty memory for some devices we are\nnot fully trust (in the sense of sustainable throughput).\n\n[akpm@linux-foundation.org: fix warning in page-writeback.c]\nSigned-off-by: Maxim Patlasov \u003cMPatlasov@parallels.com\u003e\nCc: Jan Kara \u003cjack@suse.cz\u003e\nCc: Miklos Szeredi \u003cmiklos@szeredi.hu\u003e\nCc: Wu Fengguang \u003cfengguang.wu@intel.com\u003e\nCc: Pavel Emelyanov \u003cxemul@parallels.com\u003e\nCc: James Bottomley \u003cJames.Bottomley@HansenPartnership.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "7d9f073b8da45a894bb7148433bd84d21eed6757", "tree": "513aa8ce5502ba3f1c167c7b63774136fafaac8f", "parents": [ "187320932dcece9c4b93f38f56d1f888bd5c325f" ], "author": { "name": "Wanpeng Li", "email": "liwanp@linux.vnet.ibm.com", "time": "Wed Sep 11 14:22:40 2013 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Sep 11 15:58:02 2013 -0700" }, "message": "mm/writeback: make writeback_inodes_wb static\n\nIt\u0027s not used globally and could be static.\n\nSigned-off-by: Wanpeng Li \u003cliwanp@linux.vnet.ibm.com\u003e\nCc: Dave Hansen \u003cdave.hansen@linux.intel.com\u003e\nCc: Rik van Riel \u003criel@redhat.com\u003e\nCc: Fengguang Wu \u003cfengguang.wu@intel.com\u003e\nCc: Joonsoo Kim \u003ciamjoonsoo.kim@lge.com\u003e\nCc: Johannes Weiner \u003channes@cmpxchg.org\u003e\nCc: Tejun Heo \u003ctj@kernel.org\u003e\nCc: Yasuaki Ishimatsu \u003cisimatu.yasuaki@jp.fujitsu.com\u003e\nCc: David Rientjes \u003crientjes@google.com\u003e\nCc: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nCc: Jiri Kosina \u003cjkosina@suse.cz\u003e\nCc: Wanpeng Li \u003cliwanp@linux.vnet.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "d9104d1ca9662498339c0de975b4666c30485f4e", "tree": "cb95c72dde19930ca985b9834d604958ef4eecde", "parents": [ "3b11f0aaae830f0f569cb8fb7fd26f4133ebdabd" ], "author": { "name": "Cyrill Gorcunov", "email": "gorcunov@gmail.com", "time": "Wed Sep 11 14:22:24 2013 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Sep 11 15:57:56 2013 -0700" }, "message": "mm: track vma changes with VM_SOFTDIRTY bit\n\nPavel reported that in case if vma area get unmapped and then mapped (or\nexpanded) in-place, the soft dirty tracker won\u0027t be able to recognize this\nsituation since it works on pte level and ptes are get zapped on unmap,\nloosing soft dirty bit of course.\n\nSo to resolve this situation we need to track actions on vma level, there\nVM_SOFTDIRTY flag comes in.

Secondly - most importantly - it\nfails to unlock the dquot and relock the LRU in the LRU_RETRY path.\nThis leads to deadlocks in xfstests generic/232.
