      VFS: Log the fact that we've given ELOOP rather than creating a loop · dd179946
      David Howells 提交于
      To prevent an NFS server from being used to create a directory loop in an NFS
      superblock on the client, the following patch was committed:
      
      	commit 18367501
      	Author: Al Viro <viro@zeniv.linux.org.uk>
      	Date:   Tue Jul 12 21:42:24 2011 -0400
      	Subject: fix loop checks in d_materialise_unique()
      
      This causes ELOOP to be reported to anyone trying to access the dentry that
      would otherwise cause the kernel to complete the loop.
      
      However, no indication is given to the caller as to why an operation that ought
      to work doesn't.  The fault is with the kernel, which doesn't want to try and
      solve the problem as it gets horrendously messy if there's another mountpoint
      somewhere in the trees being spliced that can't be moved[*].
      
      [*] The real problem is that we don't handle the excision of a subtree that
      gets moved _out_ of what we can see.  This can happen on the server where a
      directory is merely moved between two other dirs on the same filesystem, but
      where destination dir is not accessible by the client.
      
      So, given the choice to return ELOOP rather than trying to reconfigure the
      dentry tree, we should give the caller some indication of why they aren't being
      allowed to make what should be a legitimate request and log a message.

      Btrfs: sectorsize align offsets in fiemap · 4d479cf0
      Josef Bacik 提交于
      We've been hitting BUG()'s in btrfs_cont_expand and btrfs_fallocate and anywhere
      else that calls btrfs_get_extent while running xfstests 13 in a loop.  This is
      because fiemap is calling btrfs_get_extent with non-sectorsize aligned offsets,
      which will end up adding mappings that are not sectorsize aligned, which will
      cause problems in some cases for subsequent calls to btrfs_get_extent for
      similar areas that are sectorsize aligned.  With this patch I ran xfstests 13 in
      a loop for a couple of hours and didn't hit the problem that I could previously
      hit in at most 20 minutes.  Thanks,

      When doing the io_ctl helpers to clean up the free space cache stuff I stopped

      wonderful propblems.  Thanks,

      Btrfs: wait on caching if we're loading the free space cache · 291c7d2f
      Josef Bacik 提交于
      We've been hitting panics when running xfstest 13 in a loop for long periods of
      time.  And actually this problem has always existed so we've been hitting these
      things randomly for a while.  Basically what happens is we get a thread coming
      into the allocator and reading the space cache off of disk and adding the
      entries to the free space cache as we go.  Then we get another thread that comes
      in and tries to allocate from that block group.  Since block_group->cached !=
      BTRFS_CACHE_NO it goes ahead and tries to do the allocation.  We do this because
      if we're doing the old slow way of caching we don't want to hold people up and
      wait for everything to finish.  The problem with this is we could end up
      discarding the space cache at some arbitrary point in the future, which means we
      could very well end up allocating space that is either bad, or when the real
      caching happens it could end up thinking the space isn't in use when it really
      is and cause all sorts of other problems.
      
      The solution is to add a new flag to indicate we are loading the free space
      cache from disk, and always try to cache the block group if cache->cached !=
      BTRFS_CACHE_FINISHED.  That way if we are loading the space cache anybody else
      who tries to allocate from the block group will have to wait until it's finished
      to make sure it completes successfully.  Thanks,
