after doing some patching on aquarela, wrote a cifs/smb server
from scratch and got it down to 3350 lines of code.

it uses binary regular expressions to unpack and pack the
various nested sub-structures in the packets.

/n/sources/cinap_lenrek/cifsd.tgz
http://9hal.ath.cx/usr/cinap_lenrek/cifsd.tgz

features include:

run from listen(8) as none, so more secure.

uses syslog() for informational logging (auth/share
accesses/errors/warnings).  debug tracing can be done with a separate
debug trace file.

open/read/write/close/rename/delete files and directories.

fixed auth so it doesnt fail half the time. the trick was to delay the
auth failure to the TREE_CONNECT_ANDX, otherwise windows
will try over and over again with wrong password and username
combinations.

moving files/directories works by returning a special error code to
instruct the client to do a recursive copy.

impements/pretends enougth IPC$/rap to get the local share listed.

not implemented:

oplocks
wildcard matching (will do (again))
netbios nameservice
named pipes/mailslots
setting file attributes
NT_TRANSACT / acls
anything i'v not seen while testing with w2k and wxp

i'm interested in feedback. expecially tests with vista or w7.
