replication support
- on a WACK registration success, check that the database record
hasn't changed during the WACK processing. If it has, then fail
the registration
(This used to be commit 2acd79b95931b57efae9f7c239bc08dc143f5225)
- if we have no configured network interfaces, then don't start nbtd (when I add dynamic
interface loading this will change to a delay until a network interface comes up)
- choose the best interface by netmask for torture tests that need a
specific IP (such as the WINS test). Added iface_best_ip() for that.
- if specific interfaces are chosen in smb.conf, then keep that ordering, and
default to the first one listed
(This used to be commit 4d08c114079ef6d1d10a96195046fe43631aefa2)
registrations from anyone who isn't a current owner, then query the
owner addresses to see if they still want it.
(This used to be commit 8dc2a028d3ca0115d3173df435d926d7b6a4d5d5)
do secure server WACK responses
- added a ldap_string_to_time() function, for converting a LDAP
formatted time to a time_t
(This used to be commit 9aa3313b3f93e47e3f93028e072f6a23b3c22385)
as a human readable string. The format is designed to be able to be
used as the DN for the WINS database as well, while coping with
arbitrary bytes in the name (except nul bytes)
(This used to be commit aac3090e3504ba07124a9d480322a98efb97175e)
- more NBT packet asserts, to ensure that incoming requests have all
the elements we depend on
- open the WINS database at startup if we are configured as a WINS server
- split out the nbtd server reply packet generation code so it can be
shared by the WINS server
- re-did the logic of what is answered by the WINS server and what by
the B node server. It now always tries to answer by the B node, and
only "recurses" to the WINS server for names that are not found.
(This used to be commit 5613e6b8ad9b32639caf5055f793dbc4d0a2fc19)
- change the iface_n_*() functions to return a "const char *" instead of a "struct ipv4_addr"
I think that in general we should move towards "const char *" for
all IP addresses, as this makes IPv6 much easier, and is also easier
to debug. Andrew, when you get a chance, could you fix some of the
auth code to use strings for IPs ?
- return a NTSTATUS error on bad name queries and node status instead
of using rcode. This makes the calling code simpler.
- added low level name release code in libcli/nbt/
- use a real IP in the register and wins nbt torture tests, as w2k3
WINS server silently rejects some operations that don't come from the
IP being used (eg. it says "yes" to a release, but does not in fact
release the name)
(This used to be commit bb1ab11d8e0ea0bd9ae34aebeb565d36fe4b495f)
- when registering with a WINS server, initially use multi-homed
registration, then switch to name refresh requests. Send refresh
requests only to the WINS server that responded to our
registration. If that server goes away, then start the registration
from scratch. This makes registration more robust to WINS server
failure.
- send WINS registration requests out on our first interface rather
than an unbound interface, to avoid the problem of WACK replies
being sent to the wrong port (w2k3 WINS server does this)
(This used to be commit f7712ac7468184c07b3e3c10cb7b847ad1791dd2)
- always try to enable broadcast on nbt name sockets (this matches
samba3 behaviour better)
(This used to be commit 919bc14e7bbc04479cf11f7a7fd4c5e46616ef46)
be consistent with the function names
- added WINS client support to the NBT server. It will do initial WINS
registration, and WINS refresh, automatically failing over to
secondary WINS servers and handling multi-homed servers where we need
to register multiple IPs.
- added support for multi-homed name query replies, which are
essential for multi-homed registration as the WINS server will query
us to ensure we have the names when doing the secondary IPs in
multi-homed registration
(This used to be commit a1553fa8054dc7d33f5d77f8f95d3ffd90392b2a)
make it possible to add optimisations to the events code such as
keeping the next timed event in a sorted list, and using epoll for
file descriptor events.
I also removed the loop events code, as it wasn't being used anywhere,
and changed timed events to always be one-shot (as adding a new timed
event in the event handler is so easy to do if needed)
(This used to be commit d7b4b6de51342a65bf46fce772d313f92f8d73d3)
bind twice on each interface, once using the broadcast address and
once using the specific IP. We then only listen on the wildcard
address if we don't have "bind interface only" set. This also happens
to simplify the code that finds the right interface for an incoming
request.
(This used to be commit b3edf17281c5d82abb40dab817bf2de43f9f6c3f)
the header, and defined on the wire as a 4 byte network byte order
IP. This means the calling code doesn't have to worry about network
byte order conversions.
(This used to be commit 72048e37179dd5b9ada0c5280d2f0d8c23d1a17d)
rename the core structure to composite_context and the wait routine to
composite_wait() (suggestion from metze)
(This used to be commit cf11d05e35179c2c3e51c5ab370cd0a3fb15f24a)
broadcast name registration demands per name per interface at 1 second
intervals, then send a name overwrite request and demand. Any name
conflict replies are reported.
(This used to be commit d656fba6f1a2e9d8c03893741327e5fb59c5271e)
names on the network and answers name queries. Lots of details are
still missing, but at least this now means you don't need a Samba3
nmbd to use Samba4.
missing pieces include:
- name registrations should be "shout 3 times, then demand"
- no WINS server yet
- no master browser code
(This used to be commit d7d31fdc6670f026f96b50e51a4de19f0b920e5b)
the packets it receives, but it at least shows how the server
structure will work.
To implement it I extended the libcli/nbt/ library to allow for an
incoming packet handler to be registered. That allows the nbt client
library to be used for low level processing of the nbtd server packets.
Other changes:
- made the socket library always set SO_REUSEADDR when binding to an
interface, to ensure that restarts of a server don't have to wait
for a couple of minutes.
- made the nbt port configurable. Defaults to 137, but other ports
will be useful for testing.
(This used to be commit 2fedca6adfd4df9e85cc86896dfa79630777a917)
