This fixes our netbios scope handling. We now have a 'netbios scope' option
in smb.conf and the scope option is removed from make_nmb_name()
this was prompted by a bug in our PDC finding code where it didn't append
the scope to the query of the '*' name.
yamd is much better, and doesn't require any source code changes
if you haven't seen yamd then take a look at
http://www3.hmc.edu/~neldredge/yamd/
its excellent!
done a minimal amout of clean-up in the Makefile, removing unnecessary
modules from the link stage. this is not complete, yet, and will
involve some changes, for example to smbd, to remove dependencies on
the password database API that shouldn't be there. for example,
smbd should not ever call getsmbpwXXX() it should call the Samr or Lsa
API.
this first implementation has minor problems with not reinstantiating
the same services as the caller. the "homes" service is a good example.
damn, this one is bad.
started, at least two days ago, to add an authentication mechanism to
the smbd<->msrpc redirector/relay, such that sufficient unix / nt
information could be transferred across the unix socket to do a
become_user() on the other side of the socket.
it is necessary that the msrpc daemon inherit the same unix and nt
credentials as the smbd process from which it was spawned, until
such time as the msrpc daemon receives an authentication request
of its own, whereupon the msrpc daemon is responsible for authenticating
the new credentials and doing yet another become_user() etc sequence.
one horrible cut / paste job from smbd, plus a code split of shared
components between the two.
the job is not _yet_ complete, as i need to be able to do a become_user()
call for security reasons. i picked lsarpcd first because you don't
_need_ security on it (microsoft botched so badly on this one, it's not
real. at least they fixed this in nt5 with restrictanonymous=0x2).
fixing this involves sending the current smb and unix credentials down
the unix pipe so that the daemon it eventually goes to can pick them
up at the other end.
i can't believe this all worked!!!

capabilities to Samba so that Samba could talk to the SGI PCP
(Performance Co-Pilot) apps.
This change adds a profiling shared memory area and uses it to count
two fairly trivial things, the number of uid switches and the number
of SMB packets processes. To add more just edit include/profile.h and
then increment it at the right place.
I've also added a -P switch to smbstatus to dump the profile area.
samr_query_aliasmembers (cool!)
util_pwdb.c sids.c nmbd.c server.c smbpasswd.c swat.c :
pwdb_initialise(BOOL is_server) now creates / reads DOMAIN_NAME.SID
if is_server is True, and does LsaQueryInfoPolicy(levels 3 and 5)
to obtain member and pdc sids.
- lib/sids.c:
generate_sam_sid() modified to take a domain name: it now
generates "DOMAIN_NAME.SID". reasons:
1) if you run multiple samba servers on the same machine
under different netbios names as members of a domain,
they won't all use the same SID, which is a _big_ mistake
but it would happen _by default_.
2) we have (had) a problem with sid_to_string() and string_to_sid()
which cause SIDs to be incorrectly read. one of the major
reasons for *NOT* making this change was so as not to disrupt
existing users. but as they will be anyway by this bug,
we might as well go ahead.
- passdb/smbpass.c:
wanted to change the meaning of the name in the smbpasswd
file to an "nt" name not a "unix" name. this is probably
not a good idea: reverted this.
- output formatting / bug-fixing in rpcclient query_useraliases code.
- split sam_passwd and smb_passwd into separate higher-order function tables
- renamed struct smb_passwd's "smb_user" to "unix_user". added "nt_user"
plus user_rid, and added a "wrap" function in both sam_passwd and smb_passwd
password databases to fill in the blank entries that are not obtained
from whatever password database API instance is being used.
NOTE: whenever a struct smb_passwd or struct sam_passwd is used, it MUST
be initialised with pwdb_sam_init() or pwd_smb_init(), see chgpasswd.c
for the only example outside of the password database APIs i could find.
- added query_useraliases code to rpcclient.
- dealt with some nasty interdependencies involving non-smbd programs
and the password database API. this is still not satisfactorily
resolved completelely, but it's the best i can do for now.
- #ifdef'd out some password database options so that people don't
mistakenly set them unless they recompile to _use_ those options.
lots of debugging done, it's still not finished. the unix/NT uid/gid
and user-rid/group-rid issues are better, but not perfect. the "BUILTIN"
domain is still missing: users cannot be added to "BUILTIN" groups yet,
as we only have an "alias" db API and a "group" db API but not "builtin-alias"
db API...
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.
rpc_client/cli_pipe.c: Inlined code removed from smbdes.c

prompted by the interpret_security() dead code that Jean-Francois
pointed out I added a make target "finddead" that finds potentially
dead (ie. unused) code. It spat out 304 function names ...
I went through these are deleted many of them, making others static
(finddead also reports functions that are used only in the local
file).
in doing this I have almost certainly deleted some useful code. I may
have even prevented compilation with some compile options. I
apologise. I decided it was better to get rid of this code now and add
back the one or two functions that are needed than to keep all this
baggage.
So, if I have done a bit too much "destroying" then let me know. Keep
the swearing to a minimum :)
One bit I didn't do is the ubibt code. Chris, can you look at that?
Heaps of unused functions there. Can they be made static?
correctly. Added new parameter "stat cache size" - set to 50 by default.
I now declare the statcache code officially "open" for business :-).
It gets a hit rate of 97% with a NetBench run and seems to make
using a case insensitive run as efficient as a case sensitive run.
Also tidied up our sys_select usage - added a maxfd parameter and
also added an implementation of select in terms of poll(), for systems
where poll() is much faster. This is disabled by default.
Jeremy.
default to overwrite and smbd would default to append. Also, the -a option
(actually a toggle, such that "-a -a" would set the default) was documented
as append mode for nmbd, and *overwrite mode* for smbd.
nmbd now defaults to append mode, to match smbd. The -a option now always
means append, and I've added the -o option to both, meaning overwrite.
Note that the change to nmbd's default behavior may confuse some people.
I've not seen anything about 2.0.0 changes in the WHATSNEW.txt file.
Where would I document a change like this?
Chris -)-----
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.
