      rpc: xs_bind - do not bind when requesting a random ephemeral port · 0f7a622c
      Chris Perl 提交于
      When attempting to establish a local ephemeral endpoint for a TCP or UDP
      socket, do not explicitly call bind, instead let it happen implicilty when the
      socket is first used.
      
      The main motivating factor for this change is when TCP runs out of unique
      ephemeral ports (i.e.  cannot find any ephemeral ports which are not a part of
      *any* TCP connection).  In this situation if you explicitly call bind, then the
      call will fail with EADDRINUSE.  However, if you allow the allocation of an
      ephemeral port to happen implicitly as part of connect (or other functions),
      then ephemeral ports can be reused, so long as the combination of (local_ip,
      local_port, remote_ip, remote_port) is unique for TCP sockets on the system.
      
      This doesn't matter for UDP sockets, but it seemed easiest to treat TCP and UDP
      sockets the same.
      
      This can allow mount.nfs(8) to continue to function successfully, even in the
      face of misbehaving applications which are creating a large number of TCP
      connections.

      pnfs: fix filelayout_retry_commit when idx > 0 · 224ecbf5
      Weston Andros Adamson 提交于
      filelayout_retry_commit was recently split out from alloc_ds_commits,
      but was done in such a way that the bucket pointer always starts at
      index 0 no matter what the @idx argument is set to.
      
      The intention of the @idx argument is to retry commits starting at
      bucket @idx. This is called when alloc_ds_commits fails for a bucket.

      The original reason for this patch was because the fl_release_private
      operation couldn't sleep. With commit ed9814d8 (locks: defer freeing
      locks in locks_delete_lock until after i_lock has been dropped), this is
      no longer a problem so we can revert this patch.

       "The fixes all address recently discovered data corruption issues.
      
        The original Direct IO issue was discovered by Chris Mason @ Facebook
        on a production workload which mixed buffered reads with direct reads
        and writes IO to the same file.  The fix for that exposed other issues
        with page invalidation (exposed by millions of fsx operations) failing
        due to dirty buffers beyond EOF.
      
        Finally, the collapse_range code could also cause problems due to
        racing writeback changing the extent map while it was being shifted
        around.  The commits for that problem are simple mitigation fixes that
        prevent the problem from occuring.  A more robust fix for 3.18 that
        addresses the underlying problem is currently being worked on by
        Brian.

         - a direct IO read/buffered read data corruption
