	SUBTTL General Comments

	COMMENT ~

This Access Control Facility operates in two phases.  In the first ("profile")
phase, commands are entered to set up a database of which GETOK functions are
desired and which users need special treatment.  In the second ("policy") phase
the program implements the policy specified in the first phase by running as
the system access control facility.

This is the ACJDEC module.  This module of the access control facility
implements the initial phase (profile phase).  After the policy profile data
has been specified, a command generates a runnable ACJ.EXE which implements the
policy.

The ACJDEC module also contains the core Access Control Facility policy
program, which gets access control requests from the monitor and implements the
policy specified in the profile phase.  This module also contains subroutines
called by this module in the profile and policy phases.  These subroutines are
also called by the ACJUSR module.

The design of the program allows site specific policy implementations and
access control functions to be changed in the ACJUSR module.  It is expected
that any site should not have to change any code in the ACJDEC module,
particularly in the core access control code.  The ACJSYM module contains all
symbols that need to be shared between ACJDEC and ACJUSR.

This program was written in November 1988 by Gregory A. Scott, Digital
Equipment Corporation, Marlboro, Massachusetts.

Future enhancements to consider:
	Write logfiles with date and/or time included in filespec.
	Create some kind of idle job killer functionality.

	SUBTTL Spy on Intruder

;In order to spy on intruders (an excellent technique to discover unwanted
;tourists) the SPYON routine was stolen from another ACJ.  This intruder spy
;facility puts the user's output to a file.  

;For each intruder there is a fork in a BIN%/BIN% loop between a PTY TLINKed to
;the intruder's terminal and the suspected intruder's job.  The fork runs in
;ACJ's address space so that it can be started quickly, and is started sharing
;adress space with the top level ACJ fork.  Each fork has its own acs of course
;but also its own private stack.  The private fork's stack and the ACs are the
;only storage the subfork writes into.  Every 10 seconds it takes a TIMER
;interrupt to see if the job has moved to another terminal, logged out, or
;typed BREAK (it always redoes the spy link in case the user typed BREAK).
;After the spy fork halts, the superior fork notices on a fork termination
;interrupt and kills any spy forks that smell bad (halt or error halt status).

;AC usage in the spy on intruder fork startup code and in the spy fork:
;	P1/  User number
;	P2/  Job number
;	P3/  Log file JFN
;	P4/  PTY designator
;	P5/  PTY's TTY I/O designator

;Define a little macro to catch spy fork errors and punt the spying session.
;This is done because the fork by design does not touch any memory that the
;superior ACJ main fork might be using.

	SUBTTL Secure Files -- Access Control Cache

;[111] The Access Control Cache maintains the last NCACHE files open read for
;secure files access control.

;The SECOPN routine is called to open an ACCESS.CONTROL file for parsing.  This
;routine tries to find an entry in the cache for the directory of the filename
;passed to this routine.  Routine SECOSF is called to split the given filename
;string apart into a string containing the structure and directory and other
;string containing just the file.type.version.

;Routine SECOCF is called to find a cache entry for the str:<directory> where
;the given file resides.  If there is no entry for this directory, an entry is
;found by searching the cache for the first free cache block.  If there is no
;free block the oldest referenced cache block which is then used for this
;opening of the file.

;The cache is organized into NCACHE non-contiguous fixed buffers in memory,
;each of SCACHE contiguous pages.  A table of CBXSIZ words is used for each
;fixed buffer and contains the address of the buffer as determined at assembly
;time as well as the ASCIZ directory for which the cache is a part.

;After the cache block is idenitified, SECOCS is called to check to see that
;the entry is not "stale".  Stale entries are determined by checking the time
;that the data pages were mapped.  If stale entries were not flushed, changes
;in the ACCESS.CONTROL files would never be picked up.  If the entry is
;considered stale the cache block is invalidated.  This invalidation causes the
;file to be remapped (as if it was a new entry in the cache).  This period
;should be fairly long to avoid overhead.

;Routine SECOCO is called after the stale check.  This routine opens and maps
;the file if the cache block indicates that the file is not currently mapped.
;Finally, routine SECOCI is called to set up the pointers and counts needed to
;for routines that scan the ACCESS.CONTROL file.  

;The cached paged are then read by the normal SECCIN routine.  If the scan of
;the file causes all cached pages to be looked at, and the file was larger than
;SCACHE pages, routine SECMAP is called to map the next page in the file into
;the "overflow" buffer.  Pages are then looked at one at a time until all pages
;in the file have been mapped.

;When SECCLS is called to close the file only the overflow buffer is unmapped.
;The file stays open along with its JFNs for possible future access.  Routine
;SECFLU is called to flush an entry from the cache, unmapping all pages and
;releasing the JFN.
