1997-10-23Big change to make nmbd code more readable/understandable.Jeremy Allison1-5/+6
Main change is removal of find_name_search() confusion. This has been replaced with find_name_on_subnet() which makes it explicit what is being searched. Also changed wins_subnet to be wins_client_subnet in preparation for splitting the wins subnet into client and server pieces. This is a big nmbd change and I'd appreciate any bug reports. Specific changes follow : asyncdns.c: Removed wins entry from add_netbios_entry(). This is now explicit in the subnet_record parameter. interface.c: iface_bcast(), iface_nmask(), iface_ip() return the default interface if none can be found. Made this behavior explicit - some code in nmbd incorrectly depended upon this (reply_name_status() for instance). nameannounce.c: find_name_search changes to find_name_on_subnet. namebrowse.c: wins_subnet renamed to wins_client_subnet. namedbname.c: find_name_search removed. find_name_on_subnet added. add_netbios_entry - wins parameter removed. namedbsubnet.c: find_req_subnet removed - not explicit enough. nameelect.c: wins_subnet renamed to wins_client_subnet. namepacket.c: listening() simplified. nameresp.c: wins_subnet renamed to wins_client_subnet. nameserv.c: find_name_search moved to find_name_on_subnet. nameserv.h: FIND_XXX -> changed to FIND_SELF_NAME, FIND_ANY_NAME. nameservreply.c: find_name_search moved to find_name_on_subnet. Debug entries changed. nameservresp.c: wins_subnet renamed to wins_client_subnet. namework.c: wins_subnet renamed to wins_client_subnet. nmbd.c: wins parameter removed from add_netbios_entry. nmbsync: wins_subnet renamed to wins_client_subnet. proto.h: The usual. server.c: remove accepted fd from fd_set.

1997-10-17fix the handling of negative name query responses and the handling ofAndrew Tridgell1-20/+19
packets with no answer section in general. The fix has 2 parts: 1) set ans_name to the name we queried if nmb->answers == NULL 2) check for nmb->answers == NULL in several other places where we currently check for nmb->answers->data While doing this, I noticed there are lots of places in our nmbd code where we make assumptions about the packets being well formed. Someone could easily implement a denial of service attack on nmbd by sending a packet that causes a null pointer dereference. Does anyone feel like going through the code and adding checks? Probably the best solution is to have a single function that "validates" a packet, making sure that all the required fields are there. This will be a bit tricky as what fields are required varies a lot between packets. A first pass would be a function that prints "SUSPECT PACKET" when it hits a packet that it suspects does not have a required field (or the field is badly formatted), then we could use this on a live system to find any cases we've missed. Any takers? (This used to be commit e02c21b0b8e3ed6f2d294458160c4f632af67ed3)
1997-10-15fixed the freeze on logout bug. The fix has several parts:Andrew Tridgell1-4/+6
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)

1996-08-01local_only NetServerEnum syncs can now be issued.Samba Release Account1-27/+106
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)
