This is it ! The mega-merge of the JRA_NMBD_REWRITE branch
back into the main tree.
For the cvs logs of all the files starting nmbd_*.c, look
in the JRA_NMBD_REWRITE branch. That branch has now been
discontinued.
Jeremy.

-/************************************************************************* - search_for_name() - *************************************************************************/ - -this function is responsible for finding a name in the appropriate part -of samba's NetBIOS name database. if the name cannot be found, then it -should look the name up using DNS. later modifications will be to -forward the request on to another WINS server, should samba not be able -to find out about the requested name (this will be implemented through -issuing a new type of samba 'state'). - -the name is first searched for in the NetBIOS cache. if it cannot be -found, then it if the name looks like it's a server-type name (0x20 -0x0 or 0x1b) then DNS is used to look for the name. - -if DNS fails, then a record of this failure is kept. if it succeeds, then -a new NetBIOS entry is added. - -the successfully found name is returned. on failure, NULL is returned. - - -/************************************************************************* - expire_names() - *************************************************************************/ - -this function is responsible for removing old NetBIOS names from its -database. no further action is required. - -for over-zealous WINS systems, the use of query_refresh_names() is -recommended. this function initiates polling of hosts that have -registered with samba in its capacity as a WINS server. an alternative -means to achieve the same end as query_refresh_names() is to -reduce the time to live when the name is registered with samba, -except that in this instance the responsibility for refreshing the -name is with the owner of the name, not the server with which the name -is registered. - - -/************************************************************************* - add_netbios_entry() - *************************************************************************/ - -this function is responsible for adding or updating a NetBIOS name -in the database. into the local interface records, the only names -that will be added are those of domain master browsers and -samba's own names. into the WINS records, all names are added. - -the name to be added / updated will be looked up in the records. -if it is found, then we will not overwrite the entry if the flag -'newonly' is True, or if the name is being added as a non-SELF -(non-samba) name and the records indicate that samba owns the -name. - -otherwise, the name is added or updated with the new details. - - -/************************************************************************* - remove_netbios_entry() - *************************************************************************/ - -this function is responsible for removing a NetBIOS entry from -the database. the name is searched for in the records using -find_name_search(). if the ip is zero, then the ip is ignored. - -the name is removed if the expected source (e.g SELF, REGISTER) -matches that in the database. - - -/************************************************************************* - load_netbios_names() - *************************************************************************/ - -this function is responsible for loading any NetBIOS names that samba, -in its WINS capacity, has written out to disk. all the relevant details -are recorded in this file, including the time-to-live. should the -time left to live be small, the name is not added back in to samba's -WINS database. - - -/************************************************************************* - dump_names() - *************************************************************************/ - -this function is responsible for outputting NetBIOS names in two formats. -firstly, as debugging information, and secondly, all names that have been -registered with samba in its capacity as a WINS server are written to -disk. - -writing all WINS names allows two things. firstly, if samba's NetBIOS -daemon dies or is terminated, on restarting the daemon most if not all -of the registered WINS names will be preserved (which is a good reason -why query_netbios_names() should be used). - - -/************************************************************************* - find_name_search() - *************************************************************************/ - -this function is a wrapper around find_name(). find_name_search() can -be told whether to search for the name in a local subnet structure or -in the WINS database. on top of this, it can be told to search only -for samba's SELF names. - -if it finds the name in the WINS database, it will set the subnet_record -and also return the name it finds. - - -/************************************************************************* - find_name() - *************************************************************************/ - -this function is a low-level search function that searches a single -interface's NetBIOS records for a name. if the ip to be found is -zero then the ip address is ignored. this is to enable a name to -be found without knowing its ip address, and also to find the exact -name if a large number of group names are added with different ip -addresses. - - -/************************************************************************* - remove_name() - *************************************************************************/ - -this function is responsible for removing a specific NetBIOS entry -from a subnet list's records. only if the pointer to the entry is -in the list will the name be removed. - - -/************************************************************************* - add_name() - *************************************************************************/ - -this function is responsible for adding a NetBIOS entry into a -subnet list's records. - - -/************************************************************************* - ms_browser_name() - *************************************************************************/ - -this function returns True if the NetBIOS name passed to it is -^1^2__MSBROWSE__^2^1 - - -/************************************************************************* - name_equal() - *************************************************************************/ - -this function returns True if the two NetBIOS names passed to it -match in name, type and scope: the NetBIOS names are equal. -
