acce952 liubo 06 January 2011, 11:30:25 UTC Btrfs: forced readonly mounts on errors This patch comes from "Forced readonly mounts on errors" ideas. As we know, this is the first step in being more fault tolerant of disk corruptions instead of just using BUG() statements. The major content: - add a framework for generating errors that should result in filesystems going readonly. - keep FS state in disk super block. - make sure that all of resource will be freed and released at umount time. - make sure that fter FS is forced readonly on error, there will be no more disk change before FS is corrected. For this, we should stop write operation. After this patch is applied, the conversion from BUG() to such a framework can happen incrementally.

154bf89 Artem Bityutskiy 16 January 2011, 15:50:54 UTC mtd: mtdpart: disallow reading OOB past the end of the partition This patch fixes the mtdpart bug which allows users reading OOB past the end of the partition. This happens because 'part_read_oob()' allows reading multiple OOB areas in one go, and mtdparts does not validate the OOB length in the request. Although there is such check in 'nand_do_read_oob()' in nand_base.c, but it checks that we do not read past the flash chip, not the partition, because in nand_base.c we work with the whole chip (e.g., mtd->size in nand_base.c is the size of the whole chip). So this check cannot be done correctly in nand_base.c and should be instead done in mtdparts.c. This problem was reported by Jason Liu <r64343@freescale.com> and reproduced with nandsim: $ modprobe nandsim first_id_byte=0x20 second_id_byte=0xaa third_id_byte=0x00 \ fourth_id_byte=0x15 parts=0x400,0x400 $ modprobe nandsim mtd_oobtest.ko dev=0 $ dmesg = snip = mtd_oobtest: attempting to read past end of device mtd_oobtest: an error is expected... mtd_oobtest: error: read past end of device = snip = mtd_oobtest: finished with 2 errors Reported-by: Jason Liu <liu.h.jason@gmail.com> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com> 17 January 2011, 15:25:48 UTC

2fe17c1 Christoph Hellwig 14 January 2011, 12:07:43 UTC fallocate should be a file operation Currently all filesystems except XFS implement fallocate asynchronously, while XFS forced a commit. Both of these are suboptimal - in case of O_SYNC I/O we really want our allocation on disk, especially for the !KEEP_SIZE case where we actually grow the file with user-visible zeroes. On the other hand always commiting the transaction is a bad idea for fast-path uses of fallocate like for example in recent Samba versions. Given that block allocation is a data plane operation anyway change it from an inode operation to a file operation so that we have the file structure available that lets us check for O_SYNC. This also includes moving the code around for a few of the filesystems, and remove the already unnedded S_ISDIR checks given that we only wire up fallocate for regular files.

The naive solution is to make __set_hae() and set_hae() static inline but for reasons described in commit d559d4a24a3fe this breaks the generic kernel build. Instead, since this is architecture specific code, this patch hard wires in the architecture specific method f disabling and enabling interrupts.

But they are causing more trouble than they were supposed to solve, so it's simpler not to define them when THP is off. This is also correcting the export of pmdp_splitting_flush which is currently unused (x86 isn't using the generic implementation in mm/pgtable-generic.c and no other arch needs that [yet]).

Bring the code ordering in acpi_pci_root_init() back to sanity. Additionally, make sure that hest_disable is set when acpi_disabled is set, which is going to prevent acpi_hest_parse(), that still may be executed for acpi_disabled=1 through aer_acpi_firmware_first(), from crashing because of uninitialized hest_tab.

f03c659 Al Viro 15 January 2011, 03:30:21 UTC sanitize vfsmount refcounting changes Instead of splitting refcount between (per-cpu) mnt_count and (SMP-only) mnt_longrefs, make all references contribute to mnt_count again and keep track of how many are longterm ones. Accounting rules for longterm count: * 1 for each fs_struct.root.mnt * 1 for each fs_struct.pwd.mnt * 1 for having non-NULL ->mnt_ns * decrement to 0 happens only under vfsmount lock exclusive That allows nice common case for mntput() - since we can't drop the final reference until after mnt_longterm has reached 0 due to the rules above, mntput() can grab vfsmount lock shared and check mnt_longterm. If it turns out to be non-zero (which is the common case), we know that this is not the final mntput() and can just blindly decrement percpu mnt_count. Otherwise we grab vfsmount lock exclusive and do usual decrement-and-check of percpu mnt_count. For fs_struct.c we have mnt_make_longterm() and mnt_make_shortterm(); namespace.c uses the latter in places where we don't already hold vfsmount lock exclusive and opencodes a few remaining spots where we need to manipulate mnt_longterm. Note that we mostly revert the code outside of fs/namespace.c back to what we used to have; in particular, normal code doesn't need to care about two kinds of references, etc. And we get to keep the optimization Nick's variant had bought us...

7b8a53f Al Viro 16 January 2011, 01:08:44 UTC fix old umount_tree() breakage Expiry-related code calls umount_tree() several times with the same list to collect vfsmounts to. Which is fine, except that umount_tree() implicitly assumed that the list would be empty on each call - it moves the victims over there and then iterates through the list kicking them out. It's *almost* idempotent, so everything nearly worked. However, mnt->ghosts handling (and thus expirability checks) had been broken - that part was not idempotent... The fix is trivial - use local temporary list, splice it to the the collector list when we are through. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> 16 January 2011, 18:47:01 UTC

Hi, In fs/btrfs/inode.c::fixup_tree_root_location() we have this code: ... if (!path) { err = -ENOMEM; goto out; } ... out: btrfs_free_path(path); return err; btrfs_free_path() passes its argument on to other functions and some of them end up dereferencing the pointer. In the code above that pointer is clearly NULL, so btrfs_free_path() will eventually cause a NULL dereference. There are many ways to cut this cake (fix the bug). The one I chose was to make btrfs_free_path() deal gracefully with NULL pointers. If you disagree, feel free to come up with an alternative patch.

It is strange to the user. This patch fixes it by calcing the free space that can be used to allocate chunks. Implementation: 1. get all the devices free space, and align them by stripe length. 2. sort the devices by the free space. 3. check the free space of the devices, 3.1. if it is not zero, and then check the number of the devices that has more free space than this device, if the number of the devices is beyond the min stripe number, the free space can be used, and add into total free space. if the number of the devices is below the min stripe number, we can not use the free space, the check ends. 3.2. if the free space is zero, check the next devices, goto 3.1 This implementation is just likely fake chunk allocation.

b2117a3 Miao Xie 05 January 2011, 10:07:28 UTC btrfs: make the chunk allocator utilize the devices better With this patch, we change the handling method when we can not get enough free extents with default size. Implementation: 1. Look up the suitable free extent on each device and keep the search result. If not find a suitable free extent, keep the max free extent 2. If we get enough suitable free extents with default size, chunk allocation succeeds. 3. If we can not get enough free extents, but the number of the extent with default size is >= min_stripes, we just change the mapping information (reduce the number of stripes in the extent map), and chunk allocation succeeds. 4. If the number of the extent with default size is < min_stripes, sort the devices by its max free extent's size descending 5. Use the size of the max free extent on the (num_stripes - 1)th device as the stripe size to allocate the device space By this way, the chunk allocator can allocate chunks as large as possible when the devices' space is not enough and make full use of the devices.

1974a3b Miao Xie 05 January 2011, 10:07:24 UTC btrfs: fix wrong calculation of stripe size There are two tiny problem: - One is When we check the chunk size is greater than the max chunk size or not, we should take mirrors into account, but the original code didn't. - The other is btrfs shouldn't use the size of the residual free space as the length of of a dup chunk when doing chunk allocation. It is because the device space that a dup chunk needs is twice as large as the chunk size, if we use the size of the residual free space as the length of a dup chunk, we can not get enough free space.

d52a5b5 Miao Xie 05 January 2011, 10:07:18 UTC btrfs: try to reclaim some space when chunk allocation fails We cannot write data into files when when there is tiny space in the filesystem. Reproduce steps: # mkfs.btrfs /dev/sda1 # mount /dev/sda1 /mnt # dd if=/dev/zero of=/mnt/tmpfile0 bs=4K count=1 # dd if=/dev/zero of=/mnt/tmpfile1 bs=4K count=99999999999999 (fill the filesystem) # umount /mnt # mount /dev/sda1 /mnt # rm -f /mnt/tmpfile0 # dd if=/dev/zero of=/mnt/tmpfile0 bs=4K count=1 (failed with nospec) But if we do the last step again, we can write data successfully. The reason of the problem is that btrfs didn't try to commit the current transaction and reclaim some space when chunk allocation failed.
