This is essentially because the gendisk holds a\nreference to the mddev, and the mddev holds a reference to the\ngendisk, this a circular reference.\n\nIf we drop the reference from mddev to gendisk, then we need to ensure\nthat the mddev is destroyed when the gendisk is destroyed. However it\nis not possible to hook into the gendisk destruction process to enable\nthis.\n\nSo we drop the reference from the gendisk to the mddev and destroy the\ngendisk when the mddev gets destroyed. However this has a\ncomplication.\nBetween the call\n __blkdev_get-\u003eget_gendisk-\u003ekobj_lookup-\u003emd_probe\nand the call\n __blkdev_get-\u003emd_open\n\nthere is no obvious way to hold a reference on the mddev any more, so\nunless something is done, it will disappear and gendisk will be\ndestroyed prematurely.\n\nAlso, once we decide to destroy the mddev, there will be an unlockable\nmoment before the gendisk is unlinked (blk_unregister_region) during\nwhich a new reference to the gendisk can be created. We need to\nensure that this reference can not be used. i.e. the -\u003eopen must\nfail.\n\nSo:\n 1/ in md_probe we set a flag in the mddev (hold_active) which\n indicates that the array should be treated as active, even\n though there are no references, and no appearance of activity.\n This is cleared by md_release when the device is closed if it\n is no longer needed.\n This ensures that the gendisk will survive between md_probe and\n md_open.\n\n 2/ In md_open we check if the mddev we expect to open matches\n the gendisk that we did open.\n If there is a mismatch we return -ERESTARTSYS and modify\n __blkdev_get to retry from the top in that case.\n In the -ERESTARTSYS sys case we make sure to wait until\n the old gendisk (that we succeeded in opening) is really gone so\n we loop at most once.\n\nSome udev configurations will always open an md device when it first\nappears. If we allow an md device that was just created by an open\nto disappear on an immediate close, then this can race with such udev\nconfigurations and result in an infinite loop the device being opened\nand closed, then re-open due to the \u0027ADD\u0027 even from the first open,\nand then close and so on.\nSo we make sure an md device, once created by an open, remains active\nat least until some md \u0027ioctl\u0027 has been made on it. This means that\nall normal usage of md devices will allow them to disappear promptly\nwhen not needed, but the worst that an incorrect usage will do it\ncause an inactive md device to be left in existence (it can easily be\nremoved).\n\nAs an array can be stopped by writing to a sysfs attribute\n echo clear \u003e /sys/block/mdXXX/md/array_state\nwe need to use scheduled work for deleting the gendisk and other\nkobjects. This allows us to wait for any pending gendisk deletion to\ncomplete by simply calling flush_scheduled_work().\n\n\n\nSigned-off-by: NeilBrown \u003cneilb@suse.de\u003e\n" }, { "commit":

This implements a random 16 byte string, available\nto every ELF program via a new auxv AT_RANDOM vector.\n\n[1] http://sourceware.org/ml/libc-alpha/2008-10/msg00006.html\n\nUlrich said:\n\nglibc needs right after startup a bit of random data for internal\nprotections (stack canary etc). What is now in upstream glibc is that we\nalways unconditionally open /dev/urandom, read some data, and use it. For\nevery process startup. That\u0027s slow.\n\n...\n\nThe solution is to provide a limited amount of random data to the\nstarting process in the aux vector. I suggested 16 bytes and this is\nwhat the patch implements. If we need only 16 bytes or less we use the\ndata directly. If we need more we\u0027ll use the 16 bytes to see a PRNG.\nThis avoids the costly /dev/urandom use and it allows the kernel to use\nthe most adequate source of random data for this purpose. It might not\nbe the same pool as that for /dev/urandom.\n\nConcerns were expressed about the depletion of the randomness pool. But\nthis patch doesn\u0027t make the situation worse, it doesn\u0027t deplete entropy\nmore than happens now.\n\nSigned-off-by: Kees Cook \u003ckees.cook@canonical.com\u003e\nCc: Jakub Jelinek \u003cjakub@redhat.com\u003e\nCc: Andi Kleen \u003candi@firstfloor.org\u003e\nCc: Ulrich Drepper \u003cdrepper@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "61bce0f1371cfff497fe85594fd39d1a0b15ebe1", "tree": "97871c4148856e39ffcc8a6ffec89495018729f1", "parents": [ "f9fb860f67b9542cd78d1558dec7058092b57d8e" ], "author": { "name": "Eric W.

Ric Wheeler noticed this when using\nfs_mark with more than 1 thread, the throughput would plummet as he added\nmore threads.\n\nThis patch attempts to fix this problem by recording the average time in\nnanoseconds that it takes to commit a transaction to disk, and what time\nwe started the transaction. If we run an fsync() and we have been running\nfor less time than it takes to commit the transaction to disk, we sleep\nfor the delta amount of time and then commit to disk. We acheive\nsub-jiffie sleeping using schedule_hrtimeout. This means that the wait\ntime is auto-tuned to the speed of the underlying disk, instead of having\nthis static timeout. I weighted the average according to somebody\u0027s\ncomments (Andreas Dilger I think) in order to help normalize random\noutliers where we take way longer or way less time to commit than the\naverage. I also have a min() check in there to make sure we don\u0027t sleep\nlonger than a jiffie in case our storage is super slow, this was requested\nby Andrew.\n\nI unfortunately do not have access to a Clariion, so I had to use a\nramdisk to represent a super fast array. I tested with a SATA drive with\nbarrier\u003d1 to make sure there was no regression with local disks, I tested\nwith a 4 way multipathed Apple Xserve RAID array and of course the\nramdisk. I ran the following command\n\nfs_mark -d /mnt/ext3-test -s 4096 -n 2000 -D 64 -t $i\n\nwhere $i was 2, 4, 8, 16 and 32. I mkfs\u0027ed the fs each time.

An\n\tunusual_devs entry for Linux\u0027s own File-backed Storage Gadget\n\tis added with this flag set, since g_file_storage always\n\treports the correct capacity and since the capacity need\n\tnot be even (it is determined by the size of the backing\n\tfile).\n\n\tAn entry in unusual_devs.h which has only the CAPACITY_OK\n\tflag set shouldn\u0027t prejudice libusual, since the device will\n\twork perfectly well with either usb-storage or ub. So a\n\tnew macro, COMPLIANT_DEV, is added to let libusual know\n\tabout these entries.\n\n\tWhen a last-sector access succeeds and the total number of\n\tsectors is odd (the unexpected case, in which guessing that\n\tthe number is even might cause trouble), a WARN is triggered.\n\tThe kerneloops.org project will collect these warnings,\n\tallowing us to add CAPACITY_OK flags for the devices in\n\tquestion before implementing the default-to-even heuristic.\n\tIf users want to prevent the stack dump produced by the WARN,\n\tthey can disable the hack by adding an unusual_devs entry\n\tfor their device with the CAPACITY_OK flag.\n\n\tWhen a last-sector access fails three times in a row and\n\tneither the FIX_CAPACITY nor the CAPACITY_OK flag is set,\n\twe assume the last-sector bug is present. We replace the\n\texisting status and sense data with values that will cause\n\tthe SCSI core to fail the access immediately rather than\n\tretry indefinitely.
