In doing so I realized that much code was being
duplicated between Hangul, Big5 and Simplified
Chinese - so I re-arranged kanji.[ch] to go
through generic functions for all multibyte
characters that can be identified by a single
code range (not Kanji - but all the others).
Jeremy.
+ improvement to smbtar to allow exclusion/inclusion of system and
hidden files, and to generate a listing of what has been archived
in a format useful for automated backup systems.
+ add the "Softq" spooling system to samba's printing capabilities.
+ I have "fixed" the intrusion of US style dates into samba reporting
as well. The format yyyy/mm/dd is not only uunambiguous, but also
has the benefit of making lexicographic sorts work correctly.
Jeremy.
testparm.
In particular I added:
- ability to optionally save default values of all parameters when
calling lp_load(). This can then be used to save only non-default
parameters in lp_dump(). This makes the saved smb.conf (and viewed
parameters in testparm) much shorter
- ability to not load ipc share in lp_load()
- separators in parm_table[] so parameters can be grouped logically.
- flag to mark parameters that are local but which should be also
viewed as global as far as parameters editing is concerned
all I saw" - the book of Jeremy, chapter 1 :-).
So here is the mega-merge of the NTDOM branch server code.
It doesn't include the new client side pieces, we'll look
at that later.
This should give the same functionality, server wise, as
the NTDOM branch does, only merged into the main branch.
Any fixes to domain controler functionality should be
added to the main branch, not the NTDOM branch.
This code compiles without warnings on gcc2.8, but will
need further testing before we are sure all the working
functionality of the NTDOM server branch has been
correctly carried over.
I hereby declare the server side of the NTDOM branch
dead (and all who sail in her :-).
Jeremy.
These are some hacks on SWAT. Maybe users will actually be able to
work out how to use it now.
Unfortunately these changes required some editing in loadparm.c and
smb.h which will make Jeremys merge job harder. Sorry!
Kanji support is one case of multibyte character
support, rather than being a specific case in
single byte character support.
This allows us to add Big5 Chinese support (code page 950)
and Korean Hangul support (code page 949) at very little
cost. Also allows us to easily add future multibyte
code pages.
Makefile: Added codepages 949, 950 as we now support more multibyte
codepages.
asyncdns.c: Fixed problem with child being re-spawned when parent killed.
charcnv.c
charset.c
client.c
clitar.c
kanji.c
kanji.h
smb.h
util.c
loadparm.c: Generic multibyte codepage support (adding Big5 Chinese
and Korean Hangul).
nmbd.c: Fixed problem with child being re-spawned when parent killed.
mangle.c: Modified str_checksum so that first 15 characters have more
effect on outcome. This helps with short name mangling as
most 'long' names are still shorter than 15 chars (bug was
foobar_mng and foobar_sum would hash to the same value, with
the modified code they hash differently.
Jeremy.
loadparm.c: Added "win95 bug compatibility" parameter.
local.h: Replaced MAX_OPEN_FILES back to 100 from 10 (oops).
reply.c: Fixed ulogoff check against uid - changed to vuid.
server.c: Changed file struct save of uid - changed to vuid.
smb.h: Changed id in struct current_user to vuid.
Changed file struct uid to vuid.
time.c: Added "win95 bug compatibility" atime -> mtime return.
trans2.c: Added "win95 bug compatibility" fixes.
uid.c: Changed id in struct current_user to vuid - added checks
to set/reset it.
util.c: Added code to expand environment variables.
version.h : still at 1.9.18 (head branch doesn't matter too much at present).
Jeremy.
asyncdns.c: Fixes that went into 1.9.18p2 - allow unclocking of sigterm.
chgpasswd.c: char -> unsigned char fixes.
includes.h: AIX fix to get prototype for inet_ntoa.
local.h: Tune size of shared memory based on MAX_OPEN_FILES.
nmbd_mynames.c: Fix for nmbd repeated refresh bug.
nmbd_responserecordsdb.c: Fix for nmbd repeated refresh bug.
nmbd_winsserver.c: Fix for multi-homed registration optimisation.
smb.h: Moved default shared memory size to local.h
Jeremy.
smbmount: This is a stripped down smbclient that communicates with
the Linux 2.1.x kernel to supply authenticated smb connections for
smbfs mount points.
smbmnt/smbumount: setuid commands that do the actual smb mount system
call after having done the appropriate security checks
can't sent a oplock break twice on the same file.
changed some debug levels in the oplock code to level 0 so we can
track down a bug
zero the returned Files[] entry in find_free_file()
don't try to overcome client bugs in the handling of non-encrypted
passwords if in server level security mode
added paranoid null termination of password buffers
slight change to my ajt_panic() routine
separated out smb server-mode password validation into a separate file.
added called and calling netbios names to client gen state: referenced
section in rfc1002.txt.
created workstation trust account checking code in ntclient.c
there might be a bug in reply_session_setup_andX. i indented and added { }
around single-line if statements: the lm password checking code now doesn't
look right (around the GUEST_SESSSETUP bits). *no code semantics have been
changed by the indentation process*.
added a #define around the alignment thing: it's a way to stop
NetMonitor from decoding your packets!!!!
proto.h :
usual.
reply.c :
added what i believe to be the correct error messages for getting
correct domain joining.
smb.h :
some guesses at good names of the SAMR_XXXX functions. sorting
out the SAMR_LOOKUP_RIDS function. this is *not* the same as
the LSA_LOOKUP_RIDS function, unless paul accidentally put it
on the ntlsa pipe by mistake, instead of the samr pipe :-)
rpc_pipes/lsa_hnd.c rpc_pipes/pipe_hnd.c :
moved creation and allocation of unique policy handles into this module.
rpc_pipes/pipesamr.c rpc_pipes/samrparse.c rpc_pipes/smbparse.c :
SAMR_LOOKUP_RIDS is beginning to look _suspiciously_ like the
LSA_LOOKUP_RIDS function. but i know that there are subtle
discrepancies.
Modified Files:
---------------
Makefile:
adding extra files
ipc.c :
send_trans_reply() - alignment issue. this makes the alignment
the same as that in NT. this should be looked at by people who
understand the SMB stuff better than i.
api_fd_commands[] - added samr and wkssvc pipes.
loadparm.c :
lp_domain_controller() changed to mean "samba is a domain controller".
it's a "yes/no" parameter, now. no, it isn't used _anywhere_.
namedbwork.c nameelect.c :
if "domain controller = yes" then add SV_TYPE_DOMAIN_CTRL to the
host _and_ workgroup announcements. yes, you must do both: nt does.
namelogon.c :
important NETLOGON bug in SAMLOGON request parsing, which may be
the source of some people's problems with logging on to the Samba PDC.
password.c :
get_smbpwnam() renamed to get_smbpwd_entry().
pipes.c :
added samr and wkssvc pipes.
proto.h :
usual. can we actually _remove_ proto.h from the cvs tree, and
have it as one of the Makefile dependencies, or something?
reply.c :
get_smbpwnam() renamed to get_smbpwd_entry() - also changed response
error code when logging in from a WORKSTATION$ account. yes, paul
is right: we need to know when to return the right error code, and why.
server.c :
added call to reset_chain_pnum().
#ifdef NTDOMAIN added call to init_lsa_policy_hnd() #endif. jeremy,
you'd be proud: i did a compile without NTDOMAIN, and caught a link
error for this function.
smb.h :
defines and structures for samr and wkssvc pipes.
smbpass.c :
modified get_smbpwnam() to get_smbpwd_entry() and it now takes
two arguments. one for the name; if this is null, it looks up
by smb_userid instead.
oh, by the way, smb_userids are actually domain relative ids
(RIDs). concatenate a RID with the domain SID, and you have
an internet globally unique way of identifying a user.
we're using RIDs in the wrong way....
added mod_smbpwnam() function. this was based on code in smbpasswd.c
rpc_pipes/lsaparse.c :
added enum trusted domain parsing. this is incomplete: i need
a packet trace to write it properly.
rpc_pipes/pipe_hnd.c :
added reset_chain_pnum() function.
rpc_pipes/pipenetlog.c :
get_smbpwnam() function renamed to get_smbpwd_entry().
arcfour() issues.
removed capability of get_md4pw() function to automatically add
workstation accounts. this should either be done using
smbpasswd -add MACHINE$, or by using \PIPE\samr.
rpc_pipes/pipe_util.c :
create_pol_hnd() - creates a unique LSA Policy Handle. overkill
function: uses a 64 bit sequence number; current unix time and
the smbd pid.
rpc_pipes/smbparse.c :
arcfour() issues.
smb_io_unistr2() should advance by uni_str_len not uni_max_len.
smb_io_smb_hdr_rb() - request bind uses uint16 for the context
id, and uint8 for the num_syntaxes. oops, i put these both as
uint32s.
Added Files:
------------
rpc_pipes/lsa_hnd.c :
on the samr pipe, allocate and associate an LSA Policy Handle
with a SID. you receive queries with the LSA Policy Handle,
and have to turn this back into a SID in order to answer the
query...
rpc_pipes/pipesamr.c rpc_pipes/samrparse.c
\PIPE\samr processing. samr i presume is the SAM Replication pipe.
rpc_pipes/pipewkssvc.c rpc_pipes/wksparse.c
\PIPE\wkssvc processing. the Workstation Service pipe?
holy cow.
LSA_OPENSECRET and three other unknown #defines are commented as not
being the real defines for these!!!
rpc_pipes/pipenetlog.c :
USE_ARCFOUR for Server Password Set. and then ignore the password (agh!)
this will *fail* to do logins, by the way. i need to add a routine
to update the smb password (next job).
which are pipes on the IPC$ connection.
created mechanism to record pipe names in a separate pipes_struct. it
is planned to expand this, to return sensible things like interface
structures, and policy handles (RPC_IFACE and LSA_POL_HND). and the like.
response to Bind Acknowledgment needs a lookup table for the PIPE string
(secondary address in RPC_HDR_BA structure).
smbparse.c util.c :
interesting problem, i think caused by us typecasting a uint16* buffer
to char*. found on a SPARC.
and made it private to the 2 shmem implementations. Added new
shmops->hash_size() function.
Added code to handle the IPC system limits by looping decreasing the
size of the resources (semaphores and shared memory) that we request
until we get under the system limits, which can be quite low on some
systems!
Added checks that the creator of the IPC objects is root. Otherwise we
would be open to a security hole where someone pre-creates the shared
memory segment and attaches.
added mode for printing debug array data as chars not uint8/16/32s.
only really useful for (uint8) strings or (uint16) unicode strings
lsaparse.c smbparse.c smb.h :
rpc bind and rpc bind ack structures and parsing and creation functions.
ipc.c pipes.c pipenetlog.c pipentlsa.c pipesrvsvc.c :
using rpc bind / bind ack parsing routines instead of incorrect use of
api_LsarpcTNP1 function.
ntclient.c :
creation of do_rpc_bind() function.
THAT'S IT, FOLKS!
added bind and bind ack structures and parsing functions. restructured
rpc header stuff.
ntclient.c pipenetlog.c pipentlsa.c pipesrvsvc.c :
having to deal with restructuring above.
It will try sysv IPC first, then if that fails it will try mmap(),
then after that it will try share files.
I have defined USE_SYSV_IPC for Linux, Solaris and HPUX at the
moment. Probably a lot more could have it defined. In fact, the vast
majority of systems support it. Need autoconf again :-)
It should actually be faster than the mmap() version, and doesn't need
any lock files. This means the problem of the share mem file being on
a NFS drive will be gone.
updated Query Info Policy to report domain name and domain sid for info levels
3 and 5.
fixed bug in dom_sid_to_string (idauths decoded wrong). fixed bug in DOM_SID:
subauths are 32 bit not 16.
1) the oplock macros in smb.h used | where they should have used
&. This means that smbd thought that all clients were always
requesting oplocks. This would have _really_ confused smbclient
and smbfs when they started receiving async oplock break requests when
they don't even know what an oplock is!
2) an oplock break request from a client can be embedded in a normal
lockingX request, and will be if the client has batched any lock
requests internally. The smbd code assumed that all oplock break
requests had num_locks==num_ulocks==0 which is not true. The only
thing special about a oplock break request with
num_locks==num_ulocks==0 is that no reply is sent. Otherwise it is
processed as a normal locking request in addition to the oplock break
processing.
These two fixes get the MS mail system in Win98 working on a Samba
1.9.18 network drive.
Andrew
adding bits for new nt domain code
byteorder.h :
trying to get macros right, and not to crash on SUNOS5...
client.c :
added #ifdef NTDOMAIN, and created do_nt_login() function. don't
want to have to recompile client.c unless absolutely necessary.
credentials.c :
moved deal_with_creds() [possibly inappropriately] into credentials.c
ipc.c reply.c server.c uid.c :
attempting to make (un)become_root() functions calleable from smbclient.
this is a little tricky: smbclient might have to be another setuid
root program, immediately setuid'ing to non-root, so that we can
reset-uid to root to get at the smbpasswd file. or, have a secure
pipe mechanism to smbd to grab smbpasswd entries. or the like.
smbdes.c smbencrypt.c :
created a function to generate lm and nt owf hashes.
lsaparse.c ntclient.c smbparse.c :
added nt client LSA_AUTH2 code. it works, too!
pipenetlog.c pipentlsa.c pipesrvsvc.c :
simplification. code-shuffling. getting that damn offset right
for the opcode in RPC_HDR.
smb.h :
changed dcinfo xxx_creds to DOM_CRED structures instead of DOM_CHAL.
we might need to store the server times as well.
proto.h :
the usual.
adding start of undocumented options to do NT domain logons, client-side.
starting with LSA_REQCHAL.
the code here happily crashes smbd: i'll investigate this further... :-)
smbparse.c pipeutil.c lsaparse.c :
moved some of the common make_xxxx() functions out of pipeutil.c
so that the make_xxxx and (smb/lsa)_io_xxxx functions now sit
together. makes sense, really...
added a make_q_req_chal() function.
restructured make_rpc_reply() and called it make_rpc_hdr(). created
functions create_rpc_reply() and create_rpc_response().
pipenetlog.c pipentlsa.c pipesrvsvc.c
calling new create_rpc_reply() function instead of old make_rpc_reply().
proto.h :
usual.
smb.h:
added enum for RPC_PACKET_TYPE
redid the split that i did a year ago, taking the functions in client.c
out into clientutil.c. guess what? we could now do encrypted password
NetServerEnum2 calls in nmbd, if we wanted to.
i can now use cli_call_api() to send to different pipes. i hope.
pipenetlog.c:
allow adding to users group _and_ to admin group. if adding to
guest group, don't allow adding to users or admin as well.
smb.h :
added some pipe #defines (\PIPE\NETLOGON \PIPE\srvsvc ...)
proto.h :
usual.
added "domain other sids" parameter
pipenetlog.c :
using "domain other sids" parameter in SAM Logon response.
using new name_to_rid() function for r_uid and r_gid.
pipentlsa.c :
minor mods to do with new name_to_rid() function.
pipesrvsvc.c :
in the "net share enum" response, allocate some more space for the buffer.
there can be only 32 share entries in the response anyway. this needs
to be dealt with.
pipeutil.c :
modified name_to_rid() function to use new parameters "domain admin users"
and "domain guest users", but will otherwise do unix uid + 1000.
moved make_dom_gids() here.
proto.h:
the usual.
smb.h smbparse.c :
renamed sid_no to sid_rev_num in DOM_SID, and gid to r_gid in DOM_GID.
util.c :
moved make_dom_gids() from here.
created char *unistrn2(uint16* uni_buffer, int max_len)
added "domain admin users" parameter
added "domain guest users" parameter
these two complement the "domain groups" parameter. the "domain groups"
parameter should be for your own groups, and well-known aliases.
util.c :
added ability to do "domain groups = power_users admin_users backup_ops"
which are well-known RID aliases, not well-known RID groups.
pipenetlog.c :
combine the "domain admin users"; "domain guest users" and "domain groups"
parameters to give an array of RID groups to include in the SAM Logon
response.
ipc.c smb.h :
moved REALLOC() into smb.h
added RID #defines.
proto.h:
usual.
interface
The new code uses a source netbios name equal to the Samba servers
name, not the client name. It also uses NetWkstaUserLogon to do a full
network logon. This means it will honour the servers logon
restrictions (such as login times etc).
The shares modes code is now split into separate files. The shared
memory implementation is in locking_shm.c. The slow implementation is
in locking_slow.c
It is all controlled by a struct share_ops structure that has function
pointers to the implementation of all the functions needed by a share
modes implementation. An initialisation function sets up this
structure. This will make adding new implementations easy and clean.
This also allowed me to get rid of the ugly code in smbstatus. Now
status.c links to the locking code and calls methods in share_ops.
I also renamed some things and generally organised things in a much
cleaner fashion. Defines and structures specific to each
implementation have been moved to the appropriate file and out of
smb.h.
