+Change Log for Samba
+
+Unless otherwise attributed, all changes were made by
+Andrew.Tridgell@anu.edu.au
+
+NOTE: THIS LOG IS IN CHRONOLOGICAL ORDER
+
+
+1.5.00 announced to mailing list
+
+1.5.01 1/12/93
+ - configuration through makefile only
+ - fixed silly bug that made the client not accept dir's from
+ the server
+ - tested and updated include files for ultrix, aix and solaris
+ - several things fixed thanks to pierson@ketje.enet.dec.com
+ who provided invaluable help and advice.
+
+1.5.02 1/12/93
+ - added username option to services file so connection
+ as non guest from lanmanager is possible
+ - made server abort when it can't read/write on a socket
+ - added logging to client
+
+1.5.03 2/12/93
+ - printing now works
+ - fixed a minor bug to do with hidden and system attributes
+
+1.5.04 2/12/93
+ - added reduce_name() call to fill in security hole.
+ - cleanup up debug stuff a little
+
+1.5.05 2/12/93
+ - fixed bug in reduce_name that affects services with base paths
+ that have a soft link in them.
+
+1.5.06 3/12/93
+ - used the reserved server field in the search status to hold the
+ directory pointer. This allows lots of directories to be open
+ at once by clients without stuffing things up.
+ - preserved all the client reserved bytes in the search status
+ in case they actually use them. Hopefully this will fix the annoying
+ empty directory dir bug. (it does)
+
+1.5.07 3/12/93
+ - fixed silly bug that caused volume ids to appear twice
+ - fixed a wrote-too-few bug in smb_send()
+
+1.5.08 3/12/93
+ - did the SMBsearch properly. It can now handle recursive searches.
+ In order to keep the required dir info I encode the dirptr and
+ the current dir offset (from telldir) into 5 bytes by using a table
+ on the last 7 bits of the first byte. The first bit is always on
+ as this byte must by != 0
+ This is all put in the "server reserved" search field.
+
+1.5.09 5/12/93
+ - added a prototype nameserver. It's broken but can at least interpret
+ incoming packets.
+ - minor fixes to the server and client
+
+
+1.5.10 5/12/93
+ - fixed silly unsigned/signed char bug that made dosshell noot see all files
+ - added nmbd to Makefile
+
+1.5.11 6/12/93
+ - made the volume label appear as the service name, rather than "Remote"
+ - made the nmbd actually work (a little) for lanman for dos
+
+1.5.12 7/12/93
+ - fixed broadcasting in the nameserver
+ - the smbd now correctly sets the pid and uid
+ - nmbd now seems to work enough to satisfy the MS client.
+
+
+1.5.13 7/12/93
+ - fixed a silly bug that truncated filenames
+ - added -B option to nameserver to specify bcast address
+ - added -R option to nameserver to prevent name registering
+ - fixed minor read() bug. Does this fix the "cmp" bug?
+
+1.5.14 8/12/93
+ - fixed a bug in send_login() in the client. Thanks to
+ tim.hudson@gslmail.mincom.oz.au for pointing this out.
+ - changed name_mangle() to pad to minimum of 32 bytes with spaces
+ - changed the returned buffer size in reply_connect() to not
+ count the 4 byte length field. This fixes the "can execute" bug
+ and the "comp" bug
+ - once again re-wrote the directory pointer handling code.
+ now "tree" works correctly
+
+1.5.15 9/12/93
+ - fixed name mangle bug introduced in 1.5.14 which stopped
+ nameserver from working
+
+1.5.16 9/12/93
+ - arrgh. another silly bug in name_mangle() causes the client to die.
+
+
+1.5.17 13/12/93
+ - some cosmetic cleanups to the code
+ - changed make_connection not to lower case the password (thanks
+ to bryan@alex.com)
+ - fixed accept() bug not initialising in_addrlen (thanks to
+ bogstad@cs.jhu.edu)
+ - fixed cd bug in client.c (thanks to joergs@toppoint.de)
+ - lots of fixes to the nameserver to read_socket and
+ associated routines. It should now correctly reply to the originating
+ address and use the correct broadcast.
+ (thanks to troyer@saifr00.ateng.az.honeywell.com)
+ - SVR4 patches from mark@scot1.ucsalf.ac.uk
+ - changed the default BUFFER_SIZE to 0xFFFF
+
+1.5.18 15/12/93
+ - minor fix to reply_printqueue() to zero data buffer array.
+ - added print command to client.
+ - fixed minor bug in cmd_put() in client where a handle could
+ be closed without being previously opened.
+ - minor cleanups to the client
+ - minor solaris fixes from lonnie@itg.ti.com
+ - SYSV, shadow password and dfree() fixes from mark@scot1.ucsalf.ac.uk
+ - fixed reply_delete() to not delete read-only files
+ - fixed infinite loop in reply_delete on "del ."
+ Thanks to mark@scot1.ucsalf.ac.uk for pointing this out.
+ - posix mode definitions and changes from mark@scot1.ucsalf.ac.uk
+
+
+1.5.19 18/12/93
+ - another very minor fix to dfree().
+ - minor change to SVR4 makefile entry from rossw@march.co.uk
+ - changed reply_open not to open directories, this fixes the
+ "copy .." bug pointed out by mark@scot1.ucsalf.ac.uk
+ - changed dos_mode() so it doesn't return hidden and system info
+ on directories.
+ - changed get_dir_entry() not to descend into proc/self under linux
+ control this with the DONT_DESCEND define in includes.h
+ - changed smb_setlen() to add in the SMB id. (thanks
+ to troyer@saifr00.ateng.az.honeywell.com)
+ - fixed minor bug in reply_dir() so it won't return a ACCESS_DENIED
+ when searching a directory that is unreadable
+ - removed second stat() from get_dir_entry() (speed up)
+ - made null searches close the dirptr (fixes big filesystem problem)
+ - fixed clean_name for cd .. (from magnus@axiom.se)
+
+
+1.5.20 28/12/93
+ - added debug statement in case of SMBcreate with volid set (leefi@microsoft.com)
+ - fixed a bug in dptr_close() so it sets the next_key to a better
+ value, this fixes a annoying dir bug
+ - LOTS of changes from jeremy@netcom.com (Jeremy Allison). This
+ makes it possible to at least connect to a NT server with the client
+ and also fixes up much of the socket/process code. This also includes
+ stuff for compiling on a sun386
+ - got the client working with the Syntax server (a commercial
+ smb-based server). This required a few minor changes so the xmit
+ sizes were negotiated properly.
+ - added support for OSF1, tested on a DEC3000/400 alpha.
+ - fixed the ifconf support under ultrix
+
+1.5.21 31/12/93
+ - minor cosmetic change to reduce_name()
+ - changes for HPUX from ppk@atk.tpo.fi (Pasi Kaara)
+ - minor fix to nameserver
+ - revamped configuration file format. It now takes a Windows-style
+ (.INI style) configuration file. See the file services for
+ full details of the format. New files: loadparm.c, loadparm.h,
+ params.c, params.h, testparm.c. Several changes to smb.h, local.h,
+ server.c, Makefile. The services structure is no longer visible
+ to the rest of the system. (Karl Auer)
+ - added ability to specify a print command on a per service basis
+ and globally via the configuration file. Also allows guest account
+ to be specified in the configuration file. Made appropriate changes
+ to server.c so that these data items are obtained from the config
+ module rather than from hardcoded strings (though the hardcoded
+ strings are still the source of the defaults). (Karl Auer)
+ - renamed old-style configuration file to services.old (Karl Auer)
+ - changed README to reflect new configuration details. (Karl Auer)
+ - removed an item from the bugs wishlist (now supplied!) (Karl Auer)
+ - protected smb.h against multiple compilation. (Karl Auer)
+ - protected local.h against multiple compilation. (Karl Auer)
+ - made config stuff do dynamic allocation
+ - added "homes" capability
+ - added create_mask to each service in config
+
+1.5.22 3/1/94
+ - added "root dir" option for extra security
+ - added -n option to client (useful for OS/2)
+ - changed operation of -n to nameserver to be more useful
+ - patches from Jeremy Allison (jeremy@netcom.com)
+ fixing bug in set_message(), fixing up wait3() for SYSV,
+ making cd check the path in the client, allowing fetching to stdin
+ in client, and enhancing prompt in client to include directory.
+ - made the -D become_daemon() actually detach from the tty. This
+ may need tuning for different flavors of unix.
+ - added "dont descend" option to each service to prevent infinite
+ loops on recursive filesystems.
+ - updated README to add "running as a daemon" and a simple
+ smb.conf file.
+ - HP/UX fixes from ppk@atk.tpo.fi
+ - made lock calls only if opened with write enabled, as pointed out
+ by gadams@ddrive.demon.co.uk
+
+1.5.23 4/1/94
+ - minor fix to logging of data in receive_smb(). It used to
+ miss the last 4 bytes of packets.
+ - added the pid,uid and mid fields to the negotiation phase of
+ the client.
+ - made client able to print from stdin
+ - added password on command line for client
+ - created a sample printcap input filter "smbprint"
+ - several fixes to client to work with OS/2
+ - added mput, mget, prompt and lcd to client
+
+1.5.24 5/1/94
+ - a resend of 1.5.23 as I managed to not include the new
+ prompt, mput and mget code.
+
+1.5.25 7/1/94
+ - change -B on nameserver so it can override the broadcast address
+ - minor changes to printing in client so OS/2 server can handle it.
+ - fixed reply_access() where OK was not being initialised

+ - fix for become_daemon() for HPUX from ppk@atk.tpo.fi
+ - added "hosts allow" and "hosts deny" to server
+ - added keepalives to server
+ - added "access" feature to testparam
+ - NetBSD patches from sreiz@aie.nl
+
+1.5.26 8/1/94
+ - changed semantics of hosts access code to do more sensible defaults
+ when either of "hosts allow" or "hosts deny" is blank
+ - added the SO_KEEPALIVE option to configurations of sockets in the
+ server
+ - made some of the SVAL fns into macros to keep fussy compilers from
+ complaining
+ - fixed several null pointer bugs in check_access(). These bugs
+ made 1.5.25 unuseable for many people.
+ - fixed null pointer reference of lp_dontdescend()
+ - reload services file after each new connection.
+
+1.5.27 11/1/94
+ - fixed opening mode for reply_open() in server
+ - patches from Jeremy Allison (jeremy@netcom.com) to support the
+ "core+" protocol. The patches also inclued some other features, such
+ as a new read_with_timeout() call (used by SMBreadbraw), and auto
+ detection of the need to create a socket.
+ - changed the default KEEPALIVE value to 0, as it caused
+ problems with Lanmanager.
+ - added tar capability to client when getting files
+ - altered unix_mode() to return x bits for directories
+ - fixed bug in trim_string()
+
+1.5.28 12/1/94
+ - cleaned up the debug levels a little so debug level 1 is a practical
+ level for general use
+ - fixed a bug in add_a_service() where a freed pointer was referenced. Thanks
+ to bryan@alex.com for finding the bug.
+ - fixed bug in time structure handling in server and client. Thanks to
+ bryan@alex.com for pointing out the bug.
+
+
+1.5.29 15/1/94
+ - fixed a silly bug in reply_open(). Thanks to
+ jeremy@netcom.com for pointing this out.
+ - fixed debug levels in client to be more sensible
+ - added raw read to client
+ - added -B option to client
+ - fixed several bugs in the client, mostly to do with the tar option
+ - added -E option to client
+
+1.5.30 16/1/94
+ - added lots of prototypes so compilers don't complain
+ - fixed minor bug in reply_rename() (thanks to ppk@atk.tpo.fi)
+ - added more support for LANMAN1.0 protocol.
+ - added SESSION SETUP AND X call
+ - added READ AND X call
+ - added TREE CONNECT AND X call
+ - added support for setbuffer for HPUX (thanks to ppk@atk.tpo.fi)
+
+1.5.31 29/1/94
+ - added support for user level security in smbclient eg:
+ smbclient "\\SERVER\SHARE" -U USERNAME%PASSWORD
+ - added error message decode as per SMB File Sharing
+ protocol extensions. (thanks to merik@blackadder.dsh.oz.au)
+ - added selection masks to smbclient that recurse down directory
+ tree. eg: mget *.* with recurse and mask *.c on will retrieve all
+ *.c files in the tree.
+ - patches for FreeBSD from kuku@acds.physik.rwth-aachen.de
+ - changed reduce_name() to trim ./ from front of strings and / from
+ back
+ - fixed a nasty bug in trim_string().
+ - numerous small changes to lots of stuff that I didn't
+ document while I was doing them. Sorry :-(
+ - slightly updated sockspy
+
+ - The following was done by Karl Auer (Karl.Auer@anu.edu.au)
+ - added processing in configuration file of a [printers] section. Allows
+ connection to any printer specified in /etc/printcap (or the file
+ specified in the global parameter 'printcap name').
+ - added full processing of 'available' flag to configuration file. A
+ service can now be 'turned off' by specifying 'available = no'. Of
+ dubious utility.
+ - added 'printcap =' parameter to [global] section in the configuration
+ file. This allows the normal /etc/printcap to be bypassed when
+ checking printer names for dynamic printer connections via [printers].
+ - added 'printer name =' parameters to both the [global] section and
+ services sections of the configuration file. This allows the printer
+ name only to be set, without having to specify an entire print
+ command.
+ - added some synonyms: 'writable' and 'write ok' have the opposite sense
+ to 'read only'. 'public' may be used instead of 'guest ok'. 'printer'
+ may be used instead of 'printer name'. 'printable' is the same as
+ 'print ok'. 'root' may be used instead of 'root dir' or 'root
+ directory'.
+ - added lots more detail to the sample configuration file to take
+ account of the above.
+ - many minor fixes to internal documentation in the configuration
+ sources.
+ - also - Man pages!
+
+
+1.5.32 3/2/94
+ - addition of smbd, smbclient and testparm man pages
+ from Karl Auer
+ - zombie process fix from lendecke@namu01.gwdg.de
+ - added capability to nmbd to serve names available
+ via gethostbyname().
+
+1.5.33 3/2/94
+ - fixed up getting of netmask so it works on more unix variants
+ - added -N option to nmbd
+ - changed GMT diff calculation. need to check it's right for
+ lots of OSes
+ - fixed a bug in read_and_X() and chain_reply() chaining now
+ seems to work correctly
+
+1.5.34 4/2/94
+ - fixed bug in client that meant it couldn't get/put files from WfWg
+ - fixed a bug in the server that caused lpr to return -1 under sunos
+ - fixed a few errors in the hosts allow section of the
+ smb.conf.5 manual page and added examples
+
+1.5.35 6/2/1994
+ - minor bugfix in reduce_name().
+ - changed width of "size" in client during a dir
+ - patches for NEXT (among other things) from lendecke@namu01.gwdg.de
+ - added -a switch to server, and made default action to append
+ to log file
+ - added deadtime options to [global] section for timing out
+ dead connections to the smbd.
+ - HPUX changes from Pasi.Kaara@atk.tpo.fi
+ - made use of unsigned char more consistent
+ - changed the way of getting the default username and host in the
+ client
+ - made LANMAN1 default to on in the client, off in server.
+ Use -DLANMAN1=1 to make it on in both.
+ - lots of casts and cleanups for various operating systems
+ - changes to the Makefile from Karl to auto-instal the man pages
+ - added a short history of the project to the distribution
+
+1.5.36 15/2/94
+ - fixed minor bug in Debug() (thanks to Pasi.Kaara@atk.tpo.fi)
+ - fixed bug in server.c so -a wasn't accepted.
+ - minor fixes to the client
+ - added hosts file to name server (-H option)
+ - added -G option for groups to nameserver
+ - cleanups and additions from Jeremy Allison, taking us
+ closer to LANMAN1.0. In particular the locking code was cleaned up
+ considerably.
+
+1.5.37 16/2/94
+ - fixed bug introduced in 1.5.36 which disabled SMBcreate
+
+1.5.38 18/2/94
+ - fixed get_broadcast() for ultrix (fix from iversen@dsfys1.fi.uib.no)
+ - added automatic group registration
+ - fixed bug in registration code
+ - made nmbd work better with WfWg, and probably others
+ - updated the man pages to include the new nmbd options.
+ - minor updates to the README
+ - fixed double log_out() in send_packet().
+ - fixed bug in smbclient so that "dir" didn't work correctly
+ with pathworks
+ - possibly fixed bug in server that led to "abort retry ignore" from
+ pathworks client when doing a "dir".
+ - changed behaviour of smbclient login slightly, to try a
+ blank password in SMBtcon if the right password fails, and a
+ session setup has succeeded. Some clients seem to use a blank
+ one if a session setup has succeeded.
+ - ISC patches from imb@asstdc.scgt.oz.au
+ - the client now tries to do name registration using a unicast.
+ Let me know if this helps anyone.
+ - tried to add a "contributed" line to each OS in the Makefile.
+
+1.5.39 18/2/94
+ - fixed silly C code that only worked with some compilers
+ - fixed another silly bug in nameserv.c that caused it to seg fault
+
+1.5.40 21/2/94
+ - removed the from (IP) message so people don't worry about 0.0.0.0,
+ it's redundant anyway.
+ - changed the client so the crypt key isn't printed
+ - changed the structure of switch_message() to use a list of functions.
+ This improves the debug info.
+ - made SMBopen ignore supplied attribute as per X/Open spec
+ - made SMBopen fail if file doesn't exist in all cases. Let me know
+ if this breaks something. It is implied in the X/Open spec. This
+ fixes the pkzip bug.
+ - added dptr_demote() to replace dptr_close() to try and fix
+ pathworks dir bug. This has the potential disadvantage of
+ leaving lots of open file descriptors.
+ - changed mask_match to disallow two .s in a name
+
+1.5.41 2/3/94
+ - added "dfree command" global option to smbd to support an
+ external "disk free" executable (typically a script). This gets
+ around the problem of getting disk free info reliably on lots
+ of systems.
+ - added ffirst and fclose to client
+ - simple SYSVR4 patch from mark@scot1.ucsalf.ac.uk
+ - added better uid/gid reporting for debugging purposes
+ - several changes to the logon procedure for the client, so hopefully
+ it will connect correctly to a wider range of servers.
+ - server should no longer crash if it can't open the debug
+ file (thanks to MGK@newton.npl.co.uk)
+ - added the THANKS file.
+
+1.5.42 6/3/94
+ - lots of changes from Jeremy Allison, implementing more of
+ the LANMAN1.0 protocol, and fixing a few bugs.
+ - fixed delete bug, so hopefully wildcards are correct now
+ - pcap changes from Martin Kiff so non-aliased printers in
+ /etc/printcap are recognised
+ - wrote announce file ready for 1.6
+ - re-wrote browse code in client (still doesn't work)
+ - updates to man-pages from Karl Auer
+ - made raw packet dumps mode 0600 and only if -dA is given
+ - changed socket code to use utility functions in util.c
+
+1.6.00 17/3/94
+ - made server always return to original directory (rather than /)
+ - fixed bug in params.c that caused a seg fault if no parms in a
+ section
+ - minor clean ups for clean compile under solaris
+ - solaris fix for running from inetd from Karl Auer
+ - fixes for dfree() under solaris
+ - minor changes that might help BSDI
+ - changes to the Makefile, manual-pages and sample config file from
+ Karl Auer
+ - fixed dfree for Ultrix
+
+1.6.01 19/3/94

+
+==========
+todo:
+
+
+64 bit longs and IP addresses may give problems with unsigned longs?
+
+set archive bit whenever file is modified??
+
+fix man page dates
+
+reply only to own workgroup in server enum
+
+patch to compile with g++ and possibly solaris c++
+
+nmbd needs to keep browse list uptodate by talking to the master if it loses
+an election as others may still think its a valid backup and use it to get
+lists.
+
+leftover lock files can end up belonging to non-smbd processes after a reboot.
+
+hosts allow in nmbd
+
+hosts allow cache
+
+add password command in smbclient
+
+drag long filename to samba under os/2 gives short name
+
+document max ttl option
+
+dup/close 0 for getopt?
+
+implement SMBmove ??
+
+add option to print more info about locked files (full path, share name
+etc)
+
+very slow listing CD, perhaps because of order of stat and readdir or add
+masking to opendir?
+
+protocol drop back in client to avoid openX etc.
+
+handle exported fat drives to a long filename capable client
+
+add check for existance of lpq commands etc (use stat?)
+
+get rid of the silly +4 and -4 by removing NBT stuff
+
+write-only shares
+
+document cnvchar stuff
+
+allow smbd to serve user and group lists to win95
+
+document homes behaviour with WinDD
+
+add "hide file = *.o" "hide dir = .Foo*" "show file = xx*" type options.
+
+ALLOW_PASSWORD_CHANGE only compiles/works on some systems
+
+weird foooooooo/open.exe bug on NT
+
+%a detection can't detect Win95 versus WinNT
+
+reverse mangled maps, so (*.html *.htm) works for new files.
+
+install problems with w95. could be some sort of race?
+
+more efficient Files[] structure to handle thousands of open files
+
+lpd stuff:
+ Tony Aiuto (tony@ics.com)
+
+make max disk size local
+ \ No newline at end of file

+ *
+ * To add a parameter:
+ *
+ * 1) add it to the global or service structure definition
+ * 2) add it to the parm_table
+ * 3) add it to the list of available functions (eg: using FN_GLOBAL_STRING())
+ * 4) If it's a global then initialise it in init_globals. If a local
+ * (ie. service) parameter then initialise it in the sDefault structure
+ *
+ *
+ * Notes:
+ * The configuration file is processed sequentially for speed. It is NOT
+ * accessed randomly as happens in 'real' Windows. For this reason, there
+ * is a fair bit of sequence-dependent code here - ie., code which assumes
+ * that certain things happen before others. In particular, the code which
+ * happens at the boundary between sections is delicately poised, so be

+PARAMS.C
+
+Copyright (C) 1990, 1991, 1992, 1993, 1994 Karl Auer
+
+This module provides for streamlines retrieval of information from a
+Windows-like parameter files. There is a function which will search for
+all sections in the file and call a specified function with each. There is
+a similar function which will call a specified function for all parameters
+in a section. The idea is that you pass the addresses of suitable functions
+to a single function in this module which will then enumerate all sections,
+and within each section all parameters, to your program.
+
+Parameter files contain text lines (newline delimited) which consist of
+either a section name in square brackets or a parameter name, delimited
+from the parameter value by an equals sign. Blank lines or lines where the
+first non-whitespace character is a colon are ignored. All whitespace in
+section names and parameter names is compressed to single spaces. Leading
+and trailing whitespace on parameter names and parameter values is stripped.
+
+Only the first equals sign in a parameter line is significant - parameter
+values may contain equals signs, square brackets and semicolons. Internal
+whitespace is retained in parameter values. Parameter names may not start
+with a square bracket, an equals sign or a semicolon, for obvious reasons.
+
+A sample parameter file might look like this:
+
+[things]
+this=1
+that=2
+[other things]
+the other = 3
