2003-01-02BIG patch...Andrew Bartlett1-2/+2
This patch makes Samba compile cleanly with -Wwrite-strings. - That is, all string literals are marked as 'const'. These strings are always read only, this just marks them as such for passing to other functions. What is most supprising is that I didn't need to change more than a few lines of code (all in 'net', which got a small cleanup of net.h and extern variables). The rest is just adding a lot of 'const'. As far as I can tell, I have not added any new warnings - apart from making all of tdbutil.c's function const (so they warn for adding that const string to struct).

2002-07-28this is an interim fix for nmbd not registering DOMAIN#1b with WINSAndrew Tridgell1-1/+20
when a PDC. The fix does not iterate over all WINS tags, which it should do, but after having looked at doing that it gets *very* messy to do with our current code base. (This used to be commit 434e5124db28134ebfc9840cf0839d77987db65e)

2002-07-09the last WINS update broke self registration when we are a WINSAndrew Tridgell1-3/+4
server. The real problem is all the special cases we had for when we are a wins server as opposed to when we are using a 'real' wins server. This patch removes the special cases. We now accept non-broadcast packets from ourselves and we use ourselves as a wins server when we are one. This gets rid of the special cases and simplifies things quite a bit. It all seems to work, but there are bound to be problems found later. (This used to be commit 3e843d30158d05cdfba716bac7e5c0a75ae7a79c)
2002-06-27The next phase in the WINS rewrite!Andrew Tridgell1-110/+122
We now cope wiith multiple WINS groups and multiple failover servers for release and refresh as well as registration. We also do the regitrations in the same fashion as W2K does, where we don't try to register the next IP in the list for a name until the WINS server has acked the previos IP. This prevents us flooding the WINS server and also seems to make for much more reliable multi-homed registration. I also changed the dead WINS server code to mark pairs of IPs dead, not individual IPs. The idea is that a WINS server might be dead from the point of view of one of our interfaces, but not another, so we need to keep talking to it on one while moving onto a failover WINS server on the other interface. This copes much better with partial LAN outages and weird routing tables. (This used to be commit 313f2c9ff7a513802e4f893324865e70912d419e)
2002-06-26This commit finally gives us multiple wins server groups. We nowAndrew Tridgell1-50/+47
accept an extended syntax for 'wins server' like this: wins server = group1:192.168.2.10 group2:192.168.3.99 group1:192.168.0.1 The tags before the IPs don't mean anything, they are just a way of grouping IPs together. If you use the old syntax (ie. no ':') then an implicit group name of '*' is used. In general I'd recommend people use interface names for the group names, but it doesn't matter much. When we register in nmbd we try to register all our IPs with each group of WINS servers. We keep trying until all of them are registered with every group, falling back to the failover WINS servers for each group as we go. When we do a WINS lookup we try each of the WINS servers for each group. If a WINS server for a group gives a negative answer then we give up on that group and move to the next group. If it times out then we move to the next failover wins server in the group. In either case, if a WINS server doesn't respond then we mark it dead for 10 minutes, to prevent lengthy waits for dead servers. (This used to be commit e125f06058b6b51382cf046b1dbb30728b8aeda5)
2002-06-26- completely rewrote the wins_srv.c code. It is now much simpler, andAndrew Tridgell1-4/+12
gives us a good grounding to properly support multiple wins servers for different interfaces (which will be coming soon ...) - fixed our wins registration failover code to actually do failover! We were not trying to register with a secondary wins server at all when the primary was down. We now fallback correctly. - fixed the multi-homed name registration packets so that they work even in a non-connected network (ie. when one of our interfaces is not routable from the wins server. Yes, this really happens in the real world). (This used to be commit a049360d5b0d95a935b06aad43efc17d34de46dc)

The motivation for this system is to replace the UDP message for oplocks, but this commit only does the "set debug level" message. (This used to be commit 2a34ee95f3929cff131db6c5a2b4820194c05b2d)

2000-06-11Linux kernel oplocks now seem to work, but need a _lot_ of testingAndrew Tridgell1-1/+1
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)

2000-03-27fixed the hanlding of recursion desired when sending packets fromAndrew Tridgell1-23/+22
nmbd. It does NOT follow the rule that packets to the wins server have rec_des set (I know that we have postulated this in the past). Please don't screw with this unless you do careful testing from WinXX clients. Luke and I spent a couple of hours today getting this right (it was wrong in both TNG and HEAD) (This used to be commit 9eda2e27b74d95975e481d92930ef87de7006919)
2000-01-07this looks like a big commit, but it isn't really :)Andrew Tridgell1-7/+8
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)
2000-01-03added suppport for unexpected udp/138 packetsAndrew Tridgell1-9/+12
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)
2000-01-03added the unexpected packet database (unexpected.tdb)Andrew Tridgell1-1/+2
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)

1998-10-22Minor change.Christopher R. Hertel1-1/+1
The debug_browse_data() function does a hex dump of a browser packet. The last line is often not a full 16 bytes, which would miss-align the hex output. I've added the padding needed to align the hex output. Chris -)----- (This used to be commit 9f9b30abab118f0a2e007beddd79de38a2d5ea29)
1998-09-28Changes to test in configure if capabilities are enabled on a system.Jeremy Allison1-1/+1
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. (This used to be commit e0567433bd72aec17bf5a54cc292701095d25f09)
1998-09-05tridge the destroyer returns!Andrew Tridgell1-8/+7
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)
1998-08-30added a dest_port parameter to send_mailslot() so we send replies toAndrew Tridgell1-4/+3

1998-08-28This checking fixes the statcache bug that stopped NetBench from runningJeremy Allison1-1/+1
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)
1998-08-14this is the bug change to using connection_struct* instead of cnum.Andrew Tridgell1-1/+1
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)
1998-08-03I finished removing timestring() calls from DEBUG() messages. Also wentChristopher R. Hertel1-5/+7

Note that Jeremy has told me that he's working on adding a config parameter to turn timestamps off. Cool. Chris -)----- (This used to be commit 247dbc9a24987035a47f1ba4fa143b1e2c050e92)

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.

1998-06-09This is a first step toward moving long namelists into a database. IChristopher R. Hertel1-1/+1
split the name_record structure into pieces. The goal is that the key (the name) be separate from the data associated with the key. Databases such as gdbm store information in [key,content] pairs. There is no functional change in with this update. It's just a step in the direction that Jeremy and I have been discussing.

1998-05-12This is a security audit change of the main source.Jeremy Allison1-3/+3
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)
