[comp.protocols.nfs] PC-NFS bug using file locking

DAVISTD@MSU.BITNET (Tom Davis) (01/03/90)

I've run into a problem with PC-NFS file locking, and I believe it's a bug.
Here's the scoop:

  Two drives (E: and F) are mounted with mandatory locking (/MS parameter)
  File E:A is OPENed (AH=0x3D) for read with no locks (AL=0x40)
  Same file (E:A) is OPENed for read with no locks and then CLOSEd (AH=0x3E)
  File F:B is OPENed for read with no locks and CLOSEd
  Attempt to READ (AH=0x3F) original file returns 0 bytes (AX=0, carry clear)

I'm using PC-NFS v3.0.1 with E: mounted on a Sun3 w/SunOS v3.5 and F: mounted
on a Sun386i w/SunOS v4.0.1.
