      Also only unassign the sock from the sap if the socket
      is not zapped, because autobind can fail, leaving it
      unassigned...
      
      Noticed with llcping/llcpingd from Jay, that I'm using
      now to test PF_LLC SOCK_DGRAM (xid, test, ui).
      
      Also add more debugging calls, disabled by default in
      mainline.

      [PATCH] md - Fix problems with freeing gendisk in md.c · c39f7320
      Neil Brown authored
      md currently tries to set_capacity() *after* freeing
      the gendisk structure.
      
      It also frees the gendisk even when switching to read-only.
      
      That patch open-codes free_mddev (which is only called once)
      and cleans all this up.

      [PATCH] kNFSd 16: Remove per-client list of exports. · 0713b154
      Neil Brown authored
      This is used:
        to iterate all exports when making /proc/fs/nfs/exports
        to find all exports of a client to unexport them.
      
      The first can just as easily be done by iterating the export_table
      hash table.
      
      The second is very rarely called and can be done by iterating the
      hash table looking for exports for the given client.

      [PATCH] kNFSd 14: Filehandle lookup makes use of new export table structure. · 981d3487
      Neil Brown authored
      Filehandle lookup currently breaks out the interesting pieces of
      a filehandle and passes them to exp_get or exp_get_fsid, which put the
      pieces back into a filehandle fragment.
      
      We define a new interface "exp_find" which does a lookup based on
      a filehandle fragment to avoid this double handling.
      
      In the process, common code in exp_get_key and exp_get_fsid_key is united
      into exp_find_key.
      
      Also, filehandle composition now uses the mk_fsid_v? inline functions.

      [PATCH] kNFSd 13: Separate out the multiple keys in the export hash table. · 6d0f7b03
      Neil Brown authored
      Currently each entry in the export table had two hash chains
      going through it, one for hash-by-dev/ino,  One for hash-by-fsid.
      This is contrary to the goal of a simple hash table structure.
      
      The two hash-tables per client are replace by one which stores 'exp_key's
      which contain the key (as a file handle fragment) and a pointer to the
      real export entry.
      
      The export entries are then all stored in a single hash table indexed
      by client+vfsmount+dentry;

      [PATCH] kNFSd 12: Change exp_parent to talk directory tree, not hash table. · 37dbeea3
      Neil Brown authored
      Currently get_parent (needed to find the exportpoint
      above a given dentry) walks the hash table of export points
      checking each with is_subdir.  Now it walks up the d_parent
      link checking each for membership in the hashtable.
      
      nfsd_lookup currently does that walk too (when crossing
      a mountpoint backwards) so the code gets unified.
      
      This approach makes more sense as we move towards a cache
      for export information that can be filled on demand.
      It also assumes less about the hash table (which will change).

      [PATCH] kNFSd 11: Remove problematic "security" checks when NFS exporting. · 04146816
      Neil Brown authored
      The nfs server currently doesn't allow you to export both a
      directory and an ancestor of that directory on the same filesystem.
      
      This check is more of a problem than a solution and can be
      done in user-space if needed, so it is removed.
      
      The potential for a security problem is because the files
      below the lower directory could be accessed as though it were under
      either of the export points, and so the access control that is
      applied might not be what is expected (by the nieve admin).
      
      e.g.  export /a as readwrite and /a/b as readonly.  Then a/b/c
      can be accessed readwrite as it is in /a which might not be the
      intend.  Altering the user to this can be done in userspace though.
      
      The current restriction also stops exporting / as readonly and
      /tmp as read-write which some people want to do.  Providing
      /tmp is also exported subtree_check (the default) there is no
      security issue here.

      Neil Brown authored
      We currently store the address list with each
      client and use it only to print out comments
      on /proc/fs/nfs/exports
      While these can be helpful, they are not critical and
      could be added back later after we restructure the exports
      table.

      Instead, use d_path to find path from dentry/vfsmnt.

      [PATCH] kNFSd 3: Increase separation between lockd and nfsd. · 151ddf2e
      Neil Brown authored
      lockd currently asks nfsd for a 'client handle' for each
      request.
      
      This is used as a key for finding (or creating) a 'nlm_host'
      structure, so that there is only one of these per client...almost.
      There can currently be up to 4 nlm_hosts for a given client,
      depending on protocol (udp/tcp) or version (v1 or v4).
      
      But this isn't handled very well.
      
      So the question is: is there any advantage in having only on
      nlm_host per real host, or have we simply have one for each IP
      address that makes requests, whether they are separate hosts or not.
      
      The nlm_host structure is used:
       1/ to hold a lockd rpc client for talking to the
          remote lockd.  Having multiple lockd clients cannot hurt
          except possibly to waste a little space.
       2/ to identify resources to free when we receive notification
          from statd that a client has restarted.
          As statd gets a hostname and looks up all IP addresses,
          and then sends a notification for each IP for which it has
          a registration, there is no need to minimise the number
          of nlm_host structures (each of which register for monitoring).
       3/ to identify resources to free when a client sends a
          "free_all" request.  If a client uses multiple IP addresses to
          create locks, and then sends free_all from just one IP address
          we will loose here.
          However it is not clear that a client would ever want to send
          a free_all request, and the linux client doesn't seem to, so
          there is unlikely to be any loss here.
      
      This patch does not ask nfsd for a client identifier, but rather
      finds an nlm_host based on IP, version, protocol (udp/tcp) and
      whether we are acting as NFS server or client.
      
      All of this information is then placed in the cookie that is
      passed to statd and returned by statd when the client restarts.
      Previously only the IP address was passing the cookie, so possibly
      not all nlm_host structures would have been found.
      
      Because of these changes, lockd does not need to know
      anything about the nfsd export table, so the interface to
      nfsd is much more narrow.
      
      Another consequence is that when nfsd is told to delete a client,
      it cannot tell lockd to forget all the locks for that client.
      However it is not clear that lockd should ever forget any locks
      unless it is told to shutdown (or simulate a shutdown), and in
      anycase, the current nfsd admin tools never tell nfsd to delete
      a client anyway.

      Neil Brown authored
      both md.c and raid5.c can be compiled with debugging and compile
      errors in this code aren't normally noticed as they aren't even
      compiled.
      
      Now the debugging messages are compiled but optimised out so we will
      always see the errors.
      
      Current errors are fixed.

      [PATCH] md - 2 of 3 - Fix bug in raid5 AGAIN · 6545eefc
      Neil Brown authored
      That recent bug fix in raid5 just changed the bug, it didn't fix it.
      I think that the original code was actually wrong, which didn't
      help.
      
      This time, the code actually matches the nearby comment, that has been expanded
      a bit, so I feel somewhat more confident that it is actually right.

      When using cp to copy the shipped file to its actual name,
