      RPC: add wrapper for svc_reserve to account for checksum · cd123012
      Jeff Layton authored
      When the kernel calls svc_reserve to downsize the expected size of an RPC
      reply, it fails to account for the possibility of a checksum at the end of
      the packet.  If a client mounts a NFSv2/3 with sec=krb5i/p, and does I/O
      then you'll generally see messages similar to this in the server's ring
      buffer:
      
      RPC request reserved 164 but used 208
      
      While I was never able to verify it, I suspect that this problem is also
      the root cause of some oopses I've seen under these conditions:
      
      https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=227726
      
      
      
      This is probably also a problem for other sec= types and for NFSv4.  The
      large reserved size for NFSv4 compound packets seems to generally paper
      over the problem, however.
      
      This patch adds a wrapper for svc_reserve that accounts for the possibility
      of a checksum.  It also fixes up the appropriate callers of svc_reserve to
      call the wrapper.  For now, it just uses a hardcoded value that I
      determined via testing.  That value may need to be revised upward as things
      change, or we may want to eventually add a new auth_op that attempts to
      calculate this somehow.
      
      Unfortunately, there doesn't seem to be a good way to reliably determine
      the expected checksum length prior to actually calculating it, particularly
      with schemes like spkm3.

      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!
