      [PATCH] VFS: Make filldir_t and struct kstat deal in 64-bit inode numbers · afefdbb2
      David Howells authored
      These patches make the kernel pass 64-bit inode numbers internally when
      communicating to userspace, even on a 32-bit system.  They are required
      because some filesystems have intrinsic 64-bit inode numbers: NFS3+ and XFS
      for example.  The 64-bit inode numbers are then propagated to userspace
      automatically where the arch supports it.
      
      Problems have been seen with userspace (eg: ld.so) using the 64-bit inode
      number returned by stat64() or getdents64() to differentiate files, and
      failing because the 64-bit inode number space was compressed to 32-bits, and
      so overlaps occur.
      
      This patch:
      
      Make filldir_t take a 64-bit inode number and struct kstat carry a 64-bit
      inode number so that 64-bit inode numbers can be passed back to userspace.
      
      The stat functions then returns the full 64-bit inode number where
      available and where possible.  If it is not possible to represent the inode
      number supplied by the filesystem in the field provided by userspace, then
      error EOVERFLOW will be issued.
      
      Similarly, the getdents/readdir functions now pass the full 64-bit inode
      number to userspace where possible, returning EOVERFLOW instead when a
      directory entry is encountered that can't be properly represented.
      
      Note that this means that some inodes will not be stat'able on a 32-bit
      system with old libraries where they were before - but it does mean that
      there will be no ambiguity over what a 32-bit inode number refers to.
      
      Note similarly that directory scans may be cut short with an error on a
      32-bit system with old libraries where the scan would work before for the
      same reasons.
      
      It is judged unlikely that this situation will occur because modern glibc
      uses 64-bit capable versions of stat and getdents class functions
      exclusively, and that older systems are unlikely to encounter
      unrepresentable inode numbers anyway.

      [PATCH] NFS server subtree_check returns dubious value · 8c7b389e
      Peter Staubach authored
      Address a problem found when a Linux NFS server uses the "subtree_check"
      export option.
      
      The "subtree_check" NFS export option was designed to prohibit a client
      from using a file handle for which it should not have permission.  The
      algorithm used is to ensure that the entire path to the file being
      referenced is accessible to the user attempting to use the file handle.  If
      some part of the path is not accessible, then the operation is aborted and
      the appropriate version of ESTALE is returned to the NFS client.
      
      The error, ESTALE, is unfortunate in that it causes NFS clients to make
      certain assumptions about the continued existence of the file.  They assume
      that the file no longer exists and refuse to attempt to access it again.
      In this case, the file really does exist, but access was denied by the
      server for a particular user.
      
      A better error to return would be an EACCES sort of error.  This would
      inform the client that the particular operation that it was attempting was
      not allowed, without the nasty side effects of the ESTALE error.

      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      
      Let it rip!
