it. epoll is much more scalable than select(), but only exists on some
systems (such as Linux with the 2.6.x kernel). The code detects any
epoll system call failures at runtime and falls back to select() if
there is a problem, so it should be safe to compile this on a 2.6
kernel and run it on a 2.4.x kernel.
The speedup is quite large. It gains 20% in packet rate in the
BENCH-NBT test, on top of another 20% gain from the better timer
handling I added earlier. The really big gain will be when we are
dealing with large numbers of file descriptors. With epoll we can
handle hundreds of file descriptors all O(1), whereas with select it
is O(n).

events much more efficient (no linked lists need to be traversed, so
large numbers of timers are no problem)

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)

event handler to trigger a free that could cause a timer to be
triggered twice. This changs fixes it properly by marking timer events
to be removed using a zero next_event time.
I also changed the default timeout for events.c to be infinite, so if
there are no events to handle then smbd will sit forever doing
nothing. That allows it to be swapped out completely when idle.

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

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.

themselves are run as a single process, but run as a child of the
main process when smbd is run in the standard model, and run as part
of the main process when in the single mode.
- rewrote the winbind template code to use the new task services. Also
fixed the packet queueing
- got rid of event_context_merge() as it is no longer needed

servers in smbd. The old code still contained a fairly bit of legacy
from the time when smbd was only handling SMB connection. The new code
gets rid of all of the smb_server specific code in smbd/, and creates
a much simpler infrastructures for new server code.
Major changes include:
- simplified the process model code a lot.
- got rid of the top level server and service structures
completely. The top level context is now the event_context. This
got rid of service.h and server.h completely (they were the most
confusing parts of the old code)
- added service_stream.[ch] for the helper functions that are
specific to stream type services (services that handle streams, and
use a logically separate process per connection)
- got rid of the builtin idle_handler code in the service logic, as
none of the servers were using it, and it can easily be handled by
a server in future by adding its own timed_event to the event
context.
- fixed some major memory leaks in the rpc server code.
- added registration of servers, rather than hard coding our list of
possible servers. This allows for servers as modules in the future.
- temporarily disabled the winbind code until I add the helper
functions for that type of server
- added error checking on service startup. If a configured server
fails to startup then smbd doesn't startup.
- cleaned up the command line handling in smbd, removing unused options

files don't need to match the type names in the generated headers
- with this type mapping we no longer need definitions for the
deprecated "int32", "uint8" etc form of types. We can now force
everyone to use the standard types int32_t, uint8_t etc.
- fixed all the code that used the deprecated types
- converted the IDL types "int64" and "uint64" to "dlong" and
"udlong". These are the 4 byte aligned 64 bit integers that
Microsoft internally define as two 32 bit integers in a
structure. After discussions with Ronnie Sahlberg we decided that
calling these "int64" was confusing, as it implied a true 8 byte
aligned type
- fixed all the cases where we incorrectly used things like
"NTTIME_hyper" in our C code. The generated API now uses a NTTIME for
those. The fact that it is hyper-aligned on the wire is not relevant
to the API, and should remain just a IDL property

control of the event, so instead build that into the function. If you

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.

I decided to incorporate the udp support into the socket_ipv4.c
backend (and later in socket_ipv6.c) rather than doing a separate
backend, as so much of the code is shareable. Basically this adds a
socket_sendto() and a socket_recvfrom() call and not much all.
For udp servers, I decided to keep the call as socket_listen(), even
though dgram servers don't actually call listen(). This keeps the API
consistent.
I also added a simple local sockets testsuite in smbtorture,
