I had to modify sys_select() to not loop on EINTR. I added a wrapper
called sys_select_intr() which gives the old behaviour.
(This used to be commit b28cc4163bc2faaa80c5782fc02c8f03c410cdeb)
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.
(This used to be commit b563be824b8c3141c49558eced7829b48d4ab26f)
I also fixed up the lookup_pdc_name() code so that it now works, even
with a NT server that insists on replying to udp/138.
The method I used to match packets was to use the mailslot string as a
datagram ID. The true dgm_id doesn't work as NT doesn't set it
correctly. uggh.
PS: Jeremy, I had to change your code quite a bit, are you sure this
worked with a Samba PDC?? The code looked broken, it got the offsets
wrong in the SMB portion of the packet and filled in the IP
incorrectly.
(This used to be commit 32f66f4ea63038cb4b3785bdf1762abdde076f5d)
this means "nmblookup -S" now always works, even with broken servers
the database stores all unexpected replies and these can be accessed
by any client.
while doing this I cleaned up a couple of functions, and put in place
a better trn_id generator. in most places the code got quite a bit
simpler due to the addition of simple helper functions.
I haven't yet put the code in to take advantage of this for pdc
replies - that will be next. Jeremys pdc finding code will then work :)
(This used to be commit 280e6359d36c9bc8dcded302f15c3a1db8e3feeb)
received properly when a UDP "retry" occurs. it's because reads and
writes must be interleaved / matched.
scenario:
nmblookup connects to agent, sends request.
agent receives request, broadcasts it on 137.
agent RECEIVES 137 broadcast, sends it to nmblookup
agent receives RESPONSE to 137 broadcast, sends it to nmblookup.
if reads are not equally interspersed with writes, then second send
will fail.
if you think this is odd behaviour and that the agent should be filtering
its own UDP traffic, think again.
agent will be, potentially, redirecting nmbd traffic (including WINS
server) not just client programs.
(This used to be commit 43e158c4261e51678d6e7f77ceb4a1c7281a2525)
created an "nmb-agent" utility that, yes: it connects to the 137 socket
and accepts unix socket connections which it redirects onto port 137.
it uses the name_trn_id field to filter requests to the correct
location.
name_query() and name_status() are the first victims to use this
feature (by specifying a file descriptor of -1).
(This used to be commit d923bc8da2cf996408194d98381409191dd81a16)
reg_io_r_info() working properly. previously they weren't well
understood (well, they were the first of the registry functions i did,
back in december 97, ok??? :-)
set ntversion to 0x1 in SAMQUERY, so that we reply same as NT4 srv.

nmbd*: Changed all calls to namestr() to nmbd_namestr() to fix broken FreeBSD include
file problem...sigh.
Jeremy.

should allow us to call a function in swat rather than piping to
smbpasswd.
while doing this I also fixed quite a few "const char *" versus "char *" issues
that cropped up while using const to track down bugs in the code. This
led to changes in several generic functions.
The smbpasswd changes should be correct but they have not been
extensively tested. At least if I have introduced bugs then we should
be able to fix them more easily than before.
(This used to be commit 713864dd0322ae2ae2d83e333d85be35a7eed4ec)
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?
(This used to be commit 2204475c87f3024ea8fd1fbd7385b2def617a46f)
are now sorted by the number of common leading bits in the IP address
with the address of the querying host.
(This used to be commit 4460a1bc6aa7666d1c71d32ba73855d6ed32320a)
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.
(This used to be commit 779b924ec1f6c81ff578d22295b20fece698d1fc)
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.
(This used to be commit 068a862982bea726e8d7b1b4065d510b9840a272)
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.
(This used to be commit c7ee025ead4a85b6fa44a832047b878451845fb6)
through and changed some DEBUG() calls to DEBUGADD() to combine output
under a single timestamp. There were too many timestamps.
Note that Jeremy has told me that he's working on adding a config parameter
to turn timestamps off. Cool.

that DEBUG() provides them automatically.
There are still a few more files to do, but I've got to get home for dinner.

byte-by-byte comparisons, so it is important that the case and padding
are correct.

nmbd_become_lmb.c: Add 'force_new_election' parameter to some functions.
This allows the start of the election to be done *after*
the demotion from local master browser is done.
Also changed code so release of 1d name is done
immediately to allow other local master to gain it.
nmbd_elections.c: Ensured no elections are run until we have registered
the WORKGROUP<1e> name that we must listen on to participate
in elections.
nmbd_incomingdgrams.c: Use force_new_election code.
nmbd_namelistdb.c: Make update_name_in_namelist static.
nmbd_subnetdb.c: Fix bug in comparison function. We cannot use memcmp
as structure packing may make this fail.
nmbd_packets.c: Ensure that we only send one release packet when
sending a broadcast packet.
nmbd_workgroupdb.c: Ensure we put the correct value in the ElectionCriterion field.
nmblib.c: Ensure make_nmb_name zero's the struct nmb_name.

(This used to be commit 1fcb094ba04f01be1261ac92198c25b21b0d5ad5)
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.
(This used to be commit 2d774454005f0b54e5684cf618da7060594dfcbb)
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.
(This used to be commit ee09e9dadb69aaba5a751dd20ccc6d587d841bd6)
It is changing the global variables "myname" and "myworkgroup"
to "global_myname" and "global_myworkgroup" respectively.
This is to make it very explicit when we are messing
with a global (don't ask - it makes the domain client
code much clearer :-).

outgoing packets :
NMB_NAME_REG_OPCODE, NMB_NAME_RELEASE_OPCODE, NMB_NAME_REFRESH_OPCODE,
NMB_NAME_MULTIHOMED_REG_OPCODE.
A WINS server written by Shadow Software was rejecting our packets
as we weren't using name pointers in those requests (talk about
picky :-).

adding some debug info
pipenetlog.c pipentlsa.c pipesrvsvc.c :
using unistrn2 instead of unistr2 in the SAM logon username.
wrong offset for command in request (use "reserved" field
not cancel_count. AGH i'll get there)
(This used to be commit 6d301d2cfd25b18ba18685d926d7a5bc08695b6d)
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 178e27de0791c1ff3268cb456ed5c5efc9ac2a01)
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.
