I realised this afternoon just how easy it is to add this, so I
thought I'd implement it while the idea was fresh.
nmbd forks at startup and uses a pipe to talk to its child. The child
does the DNS lookups and the file descriptor of the child is added to
the main select loop.
While I was doing this I discovered a bug in nmbd that explains why
the dns proxy option has been so expensive. The DNS cache entries in
the WINS list were never being checked, which means we always did a
DNS lookup even if we have done it before and it is in cache. I'm sure
this used to work (I tested the DNS cache when I added it) so someone
broke it :-(
Anyway, the async DNS gets rid of the problem completely. I'll commit
just the fix to the DNS cache bug to the 1.9.17 tree.
You can disable async DNS by adding -DSYNC_DNS to the compile flags.
(This used to be commit 178e27de07)
to fix the password server code, so I didn't use SMBlib. This code is
fairly generic and uses a "struct cli_state" to hold the client
state.
(This used to be commit 3a0b5f06f4)
SAM logon sorting. too many buffer pointers. added in the missing
switch value (value of 3). dealing with the buffer pointers to the
user info structure in a slightly different way.
(This used to be commit 7993e17c9a)
whoops, the SAM Logon structure was wrong. updated this, and
cifsntdomain.txt. more debug info in pipenetlog.c. the crash
is somewhere around deal_with_credentials().
byteorder.h :
put in uint8, uint16 and uint32 typecasts around debug info, because
sign extending was resulting in ffffffe8 being displayed instead of e8.
credentials.c :
some debugging info, because i'm tracking a coredump. without gdb.
nothing like making things difficult.
reply.c :
whoops, missed this (important) bit from paul's code, which tells
the NT workstation that the MACHINE$ entry doesn't already exist,
and we're going to create a default entry with a password "machine"
right now.
proto.h:
the usual.
(This used to be commit ed606bc7d4)
changed the order of arguments to smbhash() in credentials.c. Luke,
when you changed from E1() to smbhash() you didn't notice that the
arguments are in a different order. This is why your new code was
failing.
NT logon still fails, but now gets to SAMLOGON. It shouldn't take much
to get it working now.
(This used to be commit 708edc348f)
debugging output wasn't (still isn't) perfect.
credentials.c lsaparse.c smbparse.c :
added DEBUG strings.
pipes.c :
lost some changes, to do with setup of RPC headers. arg.
(This used to be commit 9fdd697d17)
added credentials.c to smbd
credentials.c:
using credential structures instead of char*
password.c uid.c server.c:
added sid and attr to user_struct.
smbdes.c:
smbhash and str_to_key make public instead of private.
pipes.c smb.h:
lsa structures, sub-functions.
proto.h:
usual.
(This used to be commit 87a0a94485)
use UTIME structure (defined and commented in smb.h to be time, secs,
since 01jan1970)
pipes.c:
another sub-function.
util.c:
added char *unistr2(uint16 *buff) function. same as unistr except
it takes uint16* instead of char*.
smbparse.c smb.h:
more structure sorting.
proto.h:
the usual.
(This used to be commit 72a86f514f)
- move routines about a bit between smbencrypt.c and smbdes.c. Ensure
that there is no entry point for normal DES operation
- add the following comment:
This code is NOT a complete DES implementation. It implements only
the minimum necessary for SMB authentication, as used by all SMB
products (including every copy of Microsoft Windows95 ever sold)
In particular, it can only do a unchained forward DES pass. This
means it is not possible to use this code for encryption/decryption
of data, instead it is only useful as a "hash" algorithm.
There is no entry point into this code that allows normal DES operation.
I believe this means that this code does not come under ITAR
regulations but this is NOT a legal opinion. If you are concerned
about the applicability of ITAR regulations to this code then you
should confirm it for yourself (and maybe let me know if you come
up with a different answer to the one above)
(This used to be commit 35b92e725f)
1) put the encryption code in by default, with no #ifdef. It is still
disabled by default so you need to add "encrypt passwords = yes" in
smb.conf but at least all binaries will have it.
2) cleanup the kanji code so it compiles with no warnings
3) get rid of lots of uses of ugly non-portable C code. The main
offender being things like "register" but also remove uses of the
"const" keyword as there are compilers out there that don't support it
and even those that do often complain about its usage. Users don't
like warnings :-(
There is still some work to do. We need to replace the md4 code with
our own implementation. The current code (from rfc1186) is PD but is
not very portable. The new RFC (rfc1320) is more portable but adds
copyright restrictions. I'll do a from-scratch MD4 soon.
We also need to test that what I've implemented is portable. It should
be, but I'm too tired right now to test it on anything other than
intel linux.
(This used to be commit db917c62c1)
GPLd implementation so I decided to write one.
This version only does DES ecb encryption and isn't very general, so
it may in fact be exempt from ITAR regulations. ITAR regulations do
not prohibit the distribution of code that can be used for
authentication purposes only. This code has no decrypt function so it
would be useless for a normal encryption application and thus may be
ITAR exempt.
It is also very slow, but we don't need it to be fast. It is a literal
implementation from the standard and treats each bit as one byte to
make the code easy to write.
(This used to be commit c2bc073a87)
client.c: Fixed silly bugs detected on IRIX.
namedbname.c: Stopped 1d names from being registered in WINS db.
namedbsubnet.c: Only register 1e names on broadcast subnet.

have less than 10 servers listed. Fixed registering 1b
domain name issues.

the network. Needed to get around bugs in earlier nmbd
handling of DOMAIN(1b) names.
nameservreply.c:Tidied up debug message.

(This used to be commit cf23a155a1)
- change debug level on clitar stuff
- define MAP_FILE if not defined
- ensure we never set authoritative on queries in nmbd
- fake a positive response to SMBioctl, apparently this is needed for
some WfWg printer drivers
- deny file access for non-fcbopen queries when (access_allowed == AREAD && flags == O_RDWR)
- add sys_waitpid()
(This used to be commit 61e3116e57)
The 1.9.16 tree is now back to 1.9.16p2 as far as nmbd is concerned
apart from a small change that fixes the announce type in two places.
(This used to be commit 45e66a69d3)
stuff and also fix a pile of nmbd bugs. Unfortunately I found it very
hard to disentangle the new features from the bug fixes so I am
putting in the new code. I hope this is the last big pile of changes
to the 1.9.16 series!
(This used to be commit 20b6203dac)
Bressler)
- machten support from Trevor Strohman (trev@figment.tenon.com)
- added qinfo command to client as part of drag-and-drop printer
support for win95 from David Chappell <chappell@mouse.cc.trincoll.edu>
He also added the "printer driver" option
- use sigblock() on more systems and use sigsetmask(0) instead of
sigunblock() as its more portable. This beats a problem with zombies
on heavilily loaded systems.
- added internals.doc written by David Chappell into the source tree
- get rid of PRINT_COMMAND options from local.h as they are no longer
relevent
- new kanji code from Fujita
- don't set the recursion_available flag on queries in nmbd
- fix a potential bug with pointer subtraction in printing.c
- got rid of error_count code as the real fix (the EOF problem) is now
in
(This used to be commit aa6f8b04d1)
bug spotted in nameservresp.c - arguments to test subnet the response
is received on (same_net()) were the wrong way round (ccm@shentel.net)
samba was adding WORKGROUP(1e) as a unique not a group name: fixed this
bug in reply_name_status() and reply_name_query(): WINS entries weren't
being looked up.
name status reply adds local SELF entries to WINS SELF entries: some
SELF entries are only added locally, while others are only added via
WINS. name status needs to have both, combined.
a sync will only occur when an ANN_LocalMasterAnnouncement is received, NOT
an ANN_HostAnnouncement or an ANN_DomainAnnouncement.
when samba is a member of a workgroup, it looks for (using a wins server)
and announces to its domain master. NAME_QUERY_ANNOUNCE_HOST - yet another
'state' - has been created to do this: do the name query on the wins server
and send the announce host to the answer to this query.
jeremy @ vantive wrote the original code to do this, which used the
name_query() function. i'm trying to avoid name_query: it times out and
generally messes things up, but using queue_netbios_packet() and
queue_netbios_pkt_wins() is... not intuitive?
lkcl with help from jra
(This used to be commit 6e932e4bae)
prototypes automatically using "make proto". This is much less prone
to error than the old method of manually adding prototypes
(This used to be commit b551dc98f7)
and Netmask, instead replacing them with calls to routines in
interface.c
- got rid of old MAXINT define
- added code to ensure we only return one entry for each name in the ipc
enum routines
- added new_only option to add_netbios_entry() to prevent overwriting
of important names
- minor time handling fixup
(This used to be commit 7ed71b73ae)
- added dir_check_ftype() to clean up the file type checking a bit
- added check for libc version >= 5 for setfsuid() for Linux
- moved the AM_MASTER() and related macros to nameserv.h
- added proper defines for the various netbios announce types
- don't call the announce_backup() code, as I'm pretty sure its wrong
it sent ANN_GetBackupListReq packets as broadcasts, they are supposed
to be used only by clients to the master browser to find a list of
available backup servers to remote a netserverenum to, I don't think
nmbd should ever send one.
- fixed a bug in the browse list writing
- minor debug cleanups
- put in the code to discard our own broadcasts (it won't work for
multi-homed hosts though)
- changed ELECTION_VERSION to 1 so we can be beaten by a NT 3.51 server by
lowering the os level.
- only do sync_browse_lists() if we are the master browser, otherwise
we'll cause network overload
- don't call tell_become_backup() as it appears to be badly broken, it
should only be used when the machine being told has its MAINTAIN_LIST
to to auto. Not calling it does no great harm anyway
- fix a nasty bug where becomebackup was confused with reset browser!
- make setbuffer() not get caught by the auto protototypes
(This used to be commit cfbad9b082)
I've now got WINS registration working, and refresh working. Its
looking pretty good so far, but needs lots of testing.
(This used to be commit 045014aa57)
The biggest thing is the integration of Lukes new nmbd. Its still
largely untested, so we will really need some feedback
I've also added auto prototype generation and cleaned up a lot of
minor things as a result
(This used to be commit 0d8dcfa13c)
- add faq info on NT printer handling
- add "delete readonly" option to help rcs users
- add stuff to man pages on new printer options
- add "proxy name resolution" option
- add "command string" -c option to smbclient (thanks Ken)
- split time functions into time.c
- rearrange the quotas stuff a bit and fix some bugs
- complete rehash of the time handling code thanks to Paul Eggert
- fix nmblookup output a bit
- add plp print queue parsing from Bertrand Wallrich
