1997-10-22Implemented asynchronous DNS lookups in nmbd.Andrew Tridgell1-12/+20
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.

1997-10-15fixed the freeze on logout bug. The fix has several parts:Andrew Tridgell1-3/+5
1) add a new parameter to queue_netbios_packet(), the "reply_id", this is the id that should be used when sending a further response to the packet (such as a response after we get back a reply to a name query after senidnga WACK). reply_id is 0 (meaning unused) in most cases. 2) fix the id used in the reply in add_name_respond() from response_name_query_register() 3) remember to remove the response record at the end of response_name_query_register() 4) get the right IP address (it was 0.0.0.0) in response_name_query_register() 5) add a new field reply_id to struct response_record (This used to be commit e1e86c1a160c8302004ea58e4f0f5874dd179dae)

1996-10-05I have fixed quite a few important bugs in this commit.Andrew Tridgell1-6/+5
Luke, can you take special note of the bug fixes to nmbd so you can propogate them to your new code. - rewrote the code that used to use fromhost(). We now call gethostbyaddr() only if necessary and a maximum of once per connection. Calling gethostbyaddr() causes problems on some systems so avoiding it if possible is a good thing :-) - added the "fake oplocks" option. See the docs in smb.conf(5) and Speed.txt - fixed a serious bug in nmbd where it would try a DNS lookup on FIND_SELF queries. This caused a lot of unnecessary (and incorrect) DNS lookups to happen. FIND_SELF queries should only go to the internal name tables. - don't set FIND_SELF for name queries if we are a wins proxy, as we are supposed to be answering queries for other hosts. - fixed a bug in nmbd which had "if (search | FIND_LOCAL)" instead of "if (search & FIND_LOCAL)". Luke, this was in nameservreply.c - the above 3 bugs together meant that DNS queries were being cached, but the cache wasn't being used, so every query was going to DNS, no wonder nmbd has been chewing so much CPU time! Another side effect was that queries on names in lmhosts weren't being answered for bcast queries with "wins proxy" set. - ignore the maxxmit for seconday session setups (see CIFS spec) - close user opened files in a uLogoffX for user level security (see CIFS spec) - added uid into the files struct to support the above change (This used to be commit ea472b7217b7693627a13a7b1e428a0a6a3d8755)

1996-08-01local_only NetServerEnum syncs can now be issued.Samba Release Account1-43/+60
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 6e932e4bae8b46e7ff4a55a75484bad78308336a)
