the composite_context structue, we should try to convert all code
to use this because there're a lot of places where the we have
bugs with this task...
- add a composite_continue_smb2() helper
We should try to hide the internals of the composite code from the users
to avoid errors (and I found a lot of them... and will fix then step by step)
metze
(This used to be commit a16180f202)
instead make the normal composite_done() and composite_error()
functions automatically trigger a delayed callback if the caller has
had no opportunity to setup a async callback
this removes one of the common mistakes in writing a composite function
(This used to be commit f9413ce792)
Tridge, if you have the time, you might want to look at a problem I'm having
with unix domain stream sockets. From a comment in this commit:
/* Using composite_trigger_error here causes problems with the client
* socket. Linux 2.6.8 gives me a ECONNRESET on the next read after
* writing the reply when I don't wait the 100 milliseconds. */
This is in winbind/wb_cmd_userdomgroups.c:93.
The problem I have is that I can not *immediately* send an error reply to the
client because the next receive fails. Waiting 100 milliseconds helps. It
might also be a problem with epoll(), I don't really know.
I'd appreciate if you took a brief look at this, maybe I'm doing something
wrong.
Thanks,

* rename the composite helper functions from comp_* to composite_*
* Move the lsa initialization to wb_connect_lsa.c
* Equip smb_composite_connect with a fallback_to_anonymous
The latter two simplify wb_init_domain.c quite a bit.

(This used to be commit deb127e04e)
Initialize a domain structure properly. Excerpt from wb_init_domain.c:
/*
* Initialize a domain:
*
* - With schannel credentials, try to open the SMB connection with the machine
* creds. Fall back to anonymous.
*
* - If we have schannel creds, do the auth2 and open the schannel'ed netlogon
* pipe.
*
* - Open LSA. If we have machine creds, try to open with ntlmssp. Fall back
* to schannel and then to anon bind.
*
* - With queryinfopolicy, verify that we're talking to the right domain
*
* A bit complex, but with all the combinations I think it's the best we can
* get. NT4, W2k3SP1 and W2k all have different combinations, but in the end we
* have a signed&sealed lsa connection on all of them.
*
* Is this overkill? In particular the authenticated SMB connection seems a
* bit overkill, given that we do schannel for netlogon and ntlmssp for
* lsa later on w2k3, the others don't do this anyway.

Thanks to Jeremy for his detective work, and to the Samba4 team for providing
such a great infrastructure.
Next step is to connect to SAM. Do it via LDAP if we can, fall back to samr
with all we have.

the events code replaces a destructor to one that returns allways -1
while it's calling the event handler
- we don't need the composite and winsrepl specific fixes any more
- this also fixes the problem with smbcli, dcerpc, cldap, ldap and nbt
request timeouts

stuff.
- don't use SMBCLI_REQUEST_* state's in the genreic composite stuff
- move monitor_fn to libnet.
NOTE: I have maybe found some bugs, in code that is dirrectly in DONE or ERROR
state in the _send() function. I haven't fixed this bugs in this
commit! We may need some composite_trigger_*() functions or so.
And maybe some other generic helper functions...
metze
(This used to be commit 4527815a0a)
to cause an event to happen immediately. This allows metzes patch for
recognising IPs in resolve_name() to work, and also allows us to
remove some of the other code where we currently do specific checks
for is_ipaddress().
(This used to be commit 9cc000d868)
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 d7b4b6de51)
