 Hi,
 
 opendir() calls open with O_RDONLY|O_NONBLOCK but without a third
 argument which is therefore 'random' in the ktrace output.
    
 Listing a samba share on a netbsd-4 machine seems to work     
 fine here:
    
  29565      1 ls       CALL  __stat30(0x80550cc,0xbfbfe2c4)
  29565      1 ls       NAMI  "/mnt/"
  29565      1 ls       RET   __stat30 0
  29565      1 ls       CALL  open(0xbbbcd634,0,0)
  29565      1 ls       NAMI  "."
  29565      1 ls       RET   open 3
  29565      1 ls       CALL  fcntl(3,2,1)
  29565      1 ls       RET   fcntl 0
  29565      1 ls       CALL  fchdir(3)
  29565      1 ls       RET   fchdir 0
  29565      1 ls       CALL  open(0x8051800,4,1)
  29565      1 ls       NAMI  "/mnt/"
  29565      1 ls       RET   open 4
  29565      1 ls       CALL  fcntl(4,2,1)
  29565      1 ls       RET   fcntl 0
  
 The smbfs code isn't very precise with errnos. EINVAL can happen
 at many places, usually this is the result of either bad hostname
 resolution or incompatible authentication methods.
  
 Therefore it would be interesting what kind of 'samba' server is
 used. Here it is a real samba-3 but I guess in the error case it
 is a Windows server.
 
 Greetings,
