722312c326 removed some of the rough edges from the splitup -
Andrew Tridgell
f92475aa3c move soem variables from server.c that don't belong there. -
Andrew Tridgell
a6d194886a this completes the splitup of server.c.
the splitup was done with an axe, not a scalpel, so there are some
rough edges. I mostly wanted to get the general form right with fine
tuning of what goes where to come later. Still, this is better than
what we had before where server.c was a general repository for
anything that didn't fit elsewhere.
-
Andrew Tridgell
534a90ca44 more splitting of server.c
created dosmode.c and filename.c
-
Andrew Tridgell
b3d7014643 now that we have no global arrays we can start to split up the monster
server.c without breaking things.

this splits off netprot.c and fileio.c for negprot and read/write/seek
handling respectively.
-
Andrew Tridgell
b7aaab1b6b moved connection_struct handling code into smbd/conn.c and changed it
to a linked list with bitmap format.
-
Andrew Tridgell
068a862982 much cleaner chain pointer handling for both files and pipes.
the chain pointer is now stored as a static and is set whenever a
handle is created or extracted. This also makes the code less error
prone.
-
Andrew Tridgell
8bc2627ff2 some cleanups from the conversion of Pipes[] to a linked list. I also
removed most cases where a pnum is used and substituted a pipes_struct*.

in files.c I added a offset of 0x1000 to all file handles on the
wire. This makes it much less likely that bad parsing will give us the
wrong field.
-
Andrew Tridgell
79755ce970 got rid of the Files[] array completely (previously I'd just made it
private to files.c)

It now is a doubly linked list with a bitmap for allocated file
numbers. Similarly for the fd_ptr code. I also changed the default
maximum number of open files to 4096. The static cost is 1 bit per
file.

It all seems to work, and it passes the "does Sue scream" test, but if
you see weird behaviour then please investigate. With the volume of
new code that has gone in there are bound to be one or two bugs
lurking.

note that you must do a "make clean" before building this as many data
structures have changed in size.

f573a65b67 server.c: fixed a bug in close_file() with the new files.c handling code
bitmap.c: added bitmap hanlding code in preparation for increasing the
          default max open files to several thousand
-
Andrew Tridgell
b088c804f9 this checkin gets rid of the global Files[] array and makes it local
in files.c

it should now be faily easy to expand the default MAX_OPEN_FILES to
many thousands.

c7ee025ead this is the bug change to using connection_struct* instead of cnum.
Connections[] is now a local array in server.c

I might have broken something with this change. In particular the
oplock code is suspect and some .dll files aren't being oplocked when
I expected them to be. I'll look at it after I've got some sleep.

ddfbcc0581 include/smb.h: Removed dir_ptr. Not needed.
locking/locking.c: First cut a blocking lock code. #ifdef'ed out for now.
locking/locking_shm.c: Removed dir_ptr. Not needed.
smbd/nttrans.c: More work on ChangeNotify - return is not an error and needs
                to be handled as a nttrans with zero params. Removed dir_ptr. Not needed.
smbd/reply.c:
smbd/server.c:
smbd/trans2.c: Removed dir_ptr. Not needed.

Hmmm. At the moment smbclient is broken - doesn't issue prompt correctly.
This needs looking at.

162141d3b3 moved access.c into lib/ from smbd/ as it is needed by testparm. I
modified it not to need any smbd specific structures and instead pass
things from smbd.

Andrew Tridgell
90d93889d7 split the system password checking routines out of smbd/password.c and
into passdb/pass_check.c. This means SWAT no longer needs to link to
smbd/password.c

34ef55b722 loadparm.c: Added "debug timestamp" synonym for Chris.
nttrans.c: Moved common code into function in server.c
           Removed left over debug level 0.
server.c: Moved common code into function in server.c

a0748c3f53 First implementation of ChangeNotify - this version only checks
for changes in the directory modify timestamps. A better version
will look at the requested client flags, and create a hash that
represents the current state of the directory, and check against
this instead.
debug.c: Added lp_timestamp_logs() function.
loadparm.c: Added "change notify timeout" in seconds (default 60)
- this is the scan rate for a directory.
            Added ""timestamp logs" boolean - default True. Turns
off log timestamps (so I can read them :-).
nttrans.c: ChangeNotify implementation.
server.c: ChangeNotify implementation.
shmem_sysv.c: Added exits on shmem errors (without them smbd can
              core dump if some calls fail).
smb.h: Added ChangeNotify flags for future use.
util.c: Tidied up typedef.
Jeremy.

Christopher R. Hertel
60286cceca As per a Andrew's message, I went through and removed the timestring()
timestamps from several DEBUG messages.  The timestamps are redundant now
that DEBUG() provides them automatically.

There are still a few more files to do, but I've got to get home for dinner.

locking.c: Changes to implement union in files_struct.
locking_shm.c: Changes to implement union in files_struct.
nttrans.c: Made opening a directory explicit (we have to).
           Added create directory code for nttrans.
reply.c: Changes to implement union in files_struct.
server.c: Changes to implement union in files_struct. Added create directory code.
trans2.c: Changes to implement union in files_struct.
smb.h: Changes to implement union in files_struct.

        the other lists I need to implement for ChangeNotify and blocking
        locks easier.

8b25fe7341 get rid of the runtime test for broken getgroups() and add a compile
time test instead. This also allows us to get rid of the igroups
element of a couple of structures.

ef1af7fe6d chgpasswd.c: Fixed up debug calls to stop crashes if ptsname failed.
local.h: Kept FSTYPE_STRING as Samba for now.
nmbd_browsesync.c: Added bugfix from Matt Chapman mattyc@cyberdude.com
                   - lmb_browserlist is now a struct ubi_dlList not a
                   struct browse_cache_record *.

uid.c:
password.c: Removed attrs code - it is not used anywhere.

80080abf77 locking.c: Added lock type to is_locked() and do_lock()
as the code in reply_lockingX wasn't taking account of
           the difference between read and write locks ! How did this
           ever work :-) !
reply.c:
server.c: Add lock type to is_locked() and do_lock().
util.c: Also added code from klausr@ITAP.Physik.Uni-Stuttgart.De
        to fix problem with log files growing too large if an
        smbd writes less than 100 debug messages.

339b102222 Fixed bug found by Richard Sharpe. After increasing files_struct size by
MAX_OPEN_DIRECTORIES for nttrans I forgot to update the code that
enumerates the array.
Created new MAX_FNUMS in local.h, changed all code that iterates
through the files_struct array to use this.
(sorry Richard).

e01ce693f4 Code added to fix the renaming of a directory under NT SMB calls.
local.h: Changed MAXDIR to MAX_OPEN_DIRECTORIES - shmem size also tuned by this.
dir.c: Use MAX_OPEN_DIRECTORIES.
nttrans.c: Allow opening of a directory to succeed. Doesn't actually open
           a file descriptor but takes a files_struct slot marked as an
           fd.
reply.c: Changed to close any outstanding is_directory files.
         reply_close changed to understand directory files.
server.c: Added open_directory(), close_directory() calls.
smb.h: Added is_directory to files_struct.
       Changed OPEN_FNUM to check that target is !is_directory (this
       prevents the normal file calls from processing a directory
       files_struct.

4eccb47cfb loadparm.c:
With apologies to Charlton Heston and Pierre Boule.

    "You damn fools, you finally did it".

    Changed default security mode to be security=user.
    Yes this is a big (although small in code) change.
    It's something we've been discussing for a while, to
    finally wean people off the legacy security=share mode
    which is *never* what you want.

    Jeremy.

nmbd_incomingrequests.c: Bug fix for nmbd core dumps caused by overrun.

server.c: Tidyup unreadable code.
smbpasswd.c: Code to allow -U remote_username to allow ordinary
             users to change remote passwords if their NT username
             is different from their UNIX username.

5f4be1498f Fix for bug PR#8294 reported by <detlef.lammermann@er.materna.de>
- the Files array was storing the 'dos_to_unix' translated name,
rather than the untranslated name. This could case problems when
the name was run through dos_to_unix again.

fa95fae5ee ipc.c: map_username is now a BOOL function.
reply.c: map_username is now a BOOL function.
server.c: Added capability to do map_username on service names
          when looking for a home directory. That's what the
          original code would do.
lib/rpc/server/srv_util.c: Changed domain_ to builtin_ for
                           BUILTIN aliases.

smb.h:
server.c: Fix for a nastly little security problem with multi-user Windows NT
          servers and Samba where the contents of the open-file cache can end
          up being served out to users who shouldn't have access. This is some
          *seriously* ugly code.

b8fedca619 loadparm.c: Added machine password timeout parameter - set to 7 days be default.
password.c: Added code to tell server.c when machine password needs changing.
server.c: Change machine password in idle cycles if it needs it.
smbpassfile.c: Fixed up length calculations for machine password file.
smbpasswd.c: Moved domain joining code/machine password changing code.
lib/rpc/client/cli_netlogon.c: And this is where it now lives.
Jeremy.

Jeremy Allison
27ca536ad9 Abstracted all the crappy password interfaces through an indirect
function table, selectable at compile time. This should make the
code that implements all the password functions much cleaner, as
it's now very clear exactly what a particular password database
needs to provide to Samba.

3b8f5aef57 passdb.c
server.c: Moved generate_machine_sid() into passdb.c for Jean-Francois

          lock as soon as possible to prevent contention.
lib/rpc/parse/parse_samr.c
lib/rpc/server/srv_samr.c: Changed last SID-as-string manipulation

2d77445400 This is a security audit change of the main source.
It removed all ocurrences of the following functions :

sprintf
strcpy
strcat

The replacements are slprintf, safe_strcpy and safe_strcat.

It should not be possible to use code in Samba that uses
sprintf, strcpy or strcat, only the safe_equivalents.

Once Andrew has fixed the slprintf implementation then
this code will be moved back to the 1.9.18 code stream.

Jeremy.
-
Andrew Tridgell
ee09e9dadb changed to use slprintf() instead of sprintf() just about
everywhere. I've implemented slprintf() as a bounds checked sprintf()
using mprotect() and a non-writeable page.

This should prevent any sprintf based security holes.

Jeremy Allison
1fd8d12ca4 This should (hopefully :-) be the final fix for the %U %G substitution
problem....
smbpass.c: Removed Luke's dire warning - as some of the functions in here
*need* to be called externally :-).

446b98ca07 loadparm.c: Added #ifdef USE_LDAP around ldap code.
server.c: Moved %U, %G and %N into standard_sub() from standard_sub_basic()
          as only smbd knows about usernames. Also fixes problem with calling
          standard_sub_basic() from loadparm.c.
smbpass.c: Partial tidyup of machine_password_lock() code - not finished yet.
util.c: Moved %U, %G and %N into standard_sub() from standard_sub_basic()
          as only smbd knows about usernames. Also fixes problem with calling
          standard_sub_basic() from loadparm.c.
lib/rpc/server/srv_ldap_helpers.c: Added #ifdef USE_LDAP around ldap code.
lib/rpc/server/srv_samr.c: Added #ifdef USE_LDAP around ldap code.

Jeremy Allison
b5187ad6a3 Fixes for the %U and %G problems people have reported.
Essentially, multiple session_setup_and_X's may be done
to an smbd. As there is only one global variable containing
the requested connection name (sessionsetup_user), then any
subsequent sessionsetups overwrite this name (causing %U
and %G to get the wrong name). This is particularly common
when an NT client does a null session setup to get a
browse list after the user has connected, but before
a share has been mounted.

These changes store the requested_name in the vuid structure
(so this only really works for user level and above security)
and copies this name back into the global variable before
the standard_sub call.

17b94a7084 This is the checkin that adds the security=domain functionality.
WARNING - so far this has only been tested against a Samba PDC
(still waiting for IS to add me the machine accounts :-).

Still missing is the code in smbpasswd that will add a machine
account password and change it on the domain controller, but
this is not hard, and I will check it in soon.
