just do the write. This is needed because the write could return
-1/EAGAIN for dgram sockets, if the socket buffer is nearly full. The
epoll loop then goes on forever.
This was causing some failures in 'make test'

Note that this response is almost identical to the CLDAP netlogon
response, so adding that will now be quite easy.

packet. This allows much longer names to fit within the limits of NBT
name packets (rfc1002.txt also says this should be done, although
Samba3 never generates them).
The main reason for doing this is it means that our NBT name pointer
decoding code is tested with the smbtorture tests
(This used to be commit 6e2feef125daceb143c44c0c4ab73b010b311792)
registrations from anyone who isn't a current owner, then query the
owner addresses to see if they still want it.

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)
- added --case-sensitive option to nmblookup
- added case sensitivity tests to the NBT-WINS test
(This used to be commit 80a95d5688e055b36727e5c043cb36322d719763)
convert from/to DOS strings in NBT names. This will allow us to
support all foreign names as a WINS server, as long as they don't
contain a 0 byte.

- 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)
- fixed a bug in the send queue handling on timeouts
- added support for handling unexpected replies (replies to the wrong
port) at the nbtsocket layer
- added separate layer 2 code for wins refresh and wins registration
(This used to be commit 2502b02898407e3262c09a5a4aa573c5f87b8f5f)
- always try to enable broadcast on nbt name sockets (this matches
samba3 behaviour better)
(This used to be commit 919bc14e7bbc04479cf11f7a7fd4c5e46616ef46)
having the 2nd layer functions do retries themselves. This makes the
code simpler, and allows the TRN_ID to be reused in the retry (which
is how it is supposed to work).
- added support for WACK replies to nbt name requests. A WACK reply
specifies a timeout to wait for the real reply.
- added WINS name refresh async calls, supporting multiple wins
servers and multiple IPs to register
(This used to be commit 76be35cb990de830c2451d9e48cb2c40a4befdb7)
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)
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)
event code, as elements of the callers packet structure could go away
while the queue is pending (if for example a name was de-registered
while a packet referencing that name is queued)
(This used to be commit 6726f15cf44388e5787eec223a8c9778110a508f)
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.

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)
control of the event, so instead build that into the function. If you
pass NULL as mem_ctx then it leaves it as a child of the events
structure.
(This used to be commit 7f981b9ed96f39027cbfd500f41e0c2be64cbb50)
complexity was that events didn't automatically cleanup
themselves. This was because the events code was written before we had
talloc destructors, so you needed to call event_remove_XX() to clean
the event out of the event lists from every piece of code that used
events. I have now added automatic event destructors, which in turn
allowed me to simplify a lot of the calling code.
The 2nd source of complexity was caused by the ref_count, which was
needed to cope with event handlers destroying events while handling
them, which meant the linked lists became invalid, so the ref_count ws
used to mark events for later destruction.
The new system is much simpler. I now have a ev->destruction_count,
which is incremented in all event destructors. The event dispatch code
checks for changes to this and handles it.
(This used to be commit a3c7417cfeab429ffb22d5546b205818f531a7b4)
- expanded the generic async name resolver to try multiple methods
- added wins resolutions to the list of methods tried
- fixed up the random trn id generation to use the good random generator
(This used to be commit 266fd2751c01808e5a18d4094032af50554ceb7a)
which will eventually try all resolution methods setup in smb.conf
- only resolution backend at the moment is bcast, which does a
parallel broadcast to all configured network interfaces, and takes
the first reply that comes in (this nicely demonstrates how to do
parallel requests using the async APIs)
- converted all the existing code to use the new resolve_name() api
- removed all the old nmb code (yay!)
(This used to be commit 239c310f255e43dd2d1c2433f666c9faaacbdce3)
- structures defined using IDL in nbt.idl
- build around our events structure, and talloc
- fully async
- supports all NBT packet fields as per rfc1002
- easy interfaces for name query and status
For the moment there are just a couple of test functions in
namequery.c, test_name_query() and test_name_status(). These will be
removed when we hook the new library into libcli/ fully
The new library will also be a fairly good basis for a nbt
server. Although it can't be a server as-is, I wrote it with the needs
of a server in mind (for example, extremely scalable idtree based
packet handling)
