messaging system as a notification mechanism, and the speed of notification
greatly exceeds the speed of message recovery, then you get a massively (>75Mb)
growing tdb. If the message is a simple notification, then the message is
static, and you only need one of them in transit to a target process at
any one time.
This patch adds a BOOL "allow_duplicates" to the message_send_XX primitives.
If set to False, then before sending a message the sender checks the existing
message queue for a target pid for a duplicate of this message, and doesn't
add to it if one already exists.
Also added code into msgtest.c to test this.

easier to add new message types to messages.h without breaking old
binaries
- added a MSG_FORCE_ELECTION message to force nmbd to hold an election

allowing new bits of code or vfs modules to register functions without
impacting on the messaging code itself.
Also note that multiple registrations for the same message type are
possible allowing the same message to be delivered to multiple parts
of the code (possibly useful for reload messages).

The motivation for this system is to replace the UDP message for
oplocks, but this commit only does the "set debug level" message.

re-opening in some circumstances. This fixes a problem where a HUP
does not re-open logs and leaves the log open on a unlinked file.

handling in Samba. This was needed due to several limitations and
races in the previous code - as a side effect the new code is much
cleaner :)
in summary:
- changed sys_select() to avoid a signal/select race condition. It is a
rare race but once we have signals doing notification and oplocks it
is important.
- changed our main processing loop to take advantage of the new
sys_select semantics
- split the notify code into implementaion dependent and general
parts. Added the following structure that defines an implementation:
struct cnotify_fns {
void * (*register_notify)(connection_struct *conn, char *path, uint32 flags);
BOOL (*check_notify)(connection_struct *conn, uint16 vuid, char *path, uint32 flags, void *data, time_t t);
void (*remove_notify)(void *data);
};
then I wrote two implementations, one using hash/poll (like our old
code) and the other using the new Linux kernel change notify. It
should be easy to add other change notify implementations by creating
a sructure of the above type.
- fixed a bug in change notify where we were returning the wrong error
code.
- rewrote the core change notify code to be much simpler
- moved to real-time signals for leases and change notify
Amazingly, it all seems to work. I was very surprised!

Modified to do checks in timeout processing not in main loop. This (IMHO)
is the correct place as (a) we are already root, and (b) it is guarenteed
to be called every 200 smb requests.

on the glibc source code and are safer than the traditional popen as
they don't use a shell to exec the requested command. Now we have
these functions they can be tightened up (environment etc.) as required
to make a safe popen. It should now be safe to add the environement
variable loading code to loadparm.c

better "fit" with other Samba code. This is a small first step toward
doing what (I think) we agreed to do.
I've moved the key function from ubiqx/debugparse.c into lib/debug.c. I
have also moved the enum from ubiqx/debugparse.h into the debug section in
smb.h.
The next thing to do is to get debug2html added into the Makefile.in so
that it is always produced when compiling the suite.

Tidied up some of the mess (no other word for it). Still doesn't
compile cleanly. There are calls with incorrect parameters that
don't seem to be doing the right thing.
This code still needs surgery :-(.

the pre-alpha "domain group" etc parameters have disappeared.
- interactive debug detection
- re-added mem_man (andrew's memory management, detects memory corruption)
- american spellings of "initialise" replaced with english spelling of
"initialise".
- started on "lookup_name()" and "lookup_sid()" functions. proper ones.
- moved lots of functions around. created some modules of commonly used
code. e.g the password file locking code, which is used in groupfile.c
and aliasfile.c and smbpass.c
- moved RID_TYPE_MASK up another bit. this is really unfortunate, but
there is no other "fast" way to identify users from groups from aliases.
i do not believe that this code saves us anything (the multipliers)
and puts us at a disadvantage (reduces the useable rid space).
the designers of NT aren't silly: if they can get away with a user-
interface-speed LsaLookupNames / LsaLookupSids, then so can we. i
spoke with isaac at the cifs conference, the only time for example that
they do a security context check is on file create. certainly not on
individual file reads / writes, which would drastically hit their
performance and ours, too.
- renamed myworkgroup to global_sam_name, amongst other things, when used
in the rpc code. there is also a global_member_name, as we are always
responsible for a SAM database, the scope of which is limited by the role
of the machine (e.g if a member of a workgroup, your SAM is for _local_
logins only, and its name is the name of your server. you even still
have a SID. see LsaQueryInfoPolicy, levels 3 and 5).
- updated functionality of groupname.c to be able to cope with names
like DOMAIN\group and SERVER\alias. used this code to be able to
do aliases as well as groups. this code may actually be better
off being used in username mapping, too.
- created a connect to serverlist function in clientgen.c and used it
in password.c
- initialisation in server.c depends on the role of the server. well,
it does now.
- rpctorture. smbtorture. EXERCISE EXTREME CAUTION.

Changes to get Samba to compile cleanly with the IRIX compiler
with the options : -fullwarn -woff 1209,1174 (the -woff options
are to turn off warnings about unused function parameters and
controlling loop expressions being constants).
Split prototype generation as we hit a limit in IRIX nawk.
Removed "." code in smbd/filename.c (yet again :-).
Jeremy.

to check for stat64 and friends, and then changes much of Samba
to use the data type SMB_OFF_T for file size information.
stat/fstat/lstat/lseek/ftruncate have now become sys_stat etc. to hide
the 64 bit calls if needed.
Note that this still does not expose 64 bit functionality to the
client, as the changes to the reply_xxx smb's are not yet done.
This code change should make these changes possible.
Still to do before full 64 bit-ness to the client:
fcntl lock code.
statfs code
widening of dev_t and ino_t (now possible due to SMB_DEV_T and SMB_OFF_T
types being in place).
Let me know if wierd things happen after this check-in and I'll
fix them :-).

bit file interface for the NT SMB's.
Created a new define, SMB_STRUCT_STAT that currently is
defined to be struct stat - this wil change to a user
defined type containing 64 bit info when the correct
wrappers are written for 64 bit stat(), fstat() and lstat()
calls.
Also changed all sys_xxxx() calls that were previously just
wrappers to the same call prefixed by a dos_to_unix() call
into dos_xxxx() calls. This makes it explicit when a pathname
translation is being done, and when it is not.
Now, all sys_xxx() calls are meant to be wrappers to mask
OS differences, and not silently converting filenames on
the fly.

If the output line is longer than the format buffer could manage, I was
simply ignoring the additional output (that is, *not* copying it to the
format buffer--thus avoiding a buffer overrun). Instead, I now output
the current content followed by " +>\n", and then reset the format buffer.
I have never seen a debug line that exceeds the size of a pstring, but I
might as well handle the situation...just in case.

debug format buffer to be written out (and reset). fflush() is also called
to force the issue. I replaced the call to fflush() in client.c with a
call to dbgflush(), which seems to have fixed the problem that Andrew was
working on (i.e., that the prompt was not displayed when using smbclient).

Debug1() was being called like this:
Debug1( format_bufr );
but if format_bufr contains any %s or other % arguments (such as when
processing a smb.conf file containing % macros) then smbd dies a
horrible death.
The quick fix is to use:
Debug1( "%s", format_bufr);

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.

util.c itself appears to be okay).
