71db46ea66 r3586: Fix some of the issues with the module init functions.
Both subsystems and modules can now have init functions, which can be
specified in .mk files (INIT_FUNCTION = ...)

The build system will define :
 - SUBSYSTEM_init_static_modules that calls the init functions of all statically compiled modules. Failing to load will generate an error which is not fatal
 - BINARY_init_subsystems that calls the init functions (if defined) for the subsystems the binary depends on

This removes the hack with the "static bool Initialised = " and the
"lazy_init" functions

452ddd94ba r3450: portability fixes
- fix rep_inet_ntoa() for IRIX
 - lib/signal.c needs system/wait.h
 - some systems define a macro "accept", which breaks the lib/socket/ structures.
   use fn_ as a prefix for the structure elements to avoid the problem

284349482f r3443: the next stage in the include files re-organisation.
I have created the include/system/ directory, which will contain the
wrappers for the system includes for logical subsystems. So far I have
created include/system/kerberos.h and include/system/network.h, which
contain all the system includes for kerberos code and networking code.
These are the included in subsystems that need kerberos or networking
respectively.

Note that this method avoids the mess of #ifdef HAVE_XXX_H in every C
file, instead each C module includes the include/system/XXX.h file for
the logical system support it needs, and the details are kept isolated
in include/system/

This patch also creates a "struct ipv4_addr" which replaces "struct
in_addr" in our code. That avoids every C file needing to import all
the system networking headers.

990d76f7cb r3314: added a option "socket:testnonblock" to the generic socket code. If
you set this option (either on the command line using --option or in
smb.conf) then every socket recv or send will return short by random
amounts. This allows you to test that the non-blocking socket logic in
your code works correctly.

I also removed the flags argument to socket_accept(), and instead made
the new socket inherit the flags of the old socket, which makes more
sense to me.

c6888da148 r3304: changed the API to lib/socket/ a little.
The main change is to make socket_recv() take a pre-allocated buffer,
rather than allocating one itself. This allows non-blocking users of
this API to avoid a memcpy(). As a result our messaging code is now
about 10% faster, and the ncacn_ip_tcp and ncalrpc code is also
faster.

The second change was to remove the unused mem_ctx argument from
socket_send(). Having it there implied that memory could be allocated,
which meant the caller had to worry about freeing that memory (if for
example it is sending in a tight loop using the same memory
context). Removing that unused argument keeps life simpler for users.

1f6fd130a3 r3279: Removed MSG_DONTWAIT flags as many platform don't have it.
If a socket is non-blocking then adding MSG_DONTWAIT is pointless (it
does nothing), so all we lose is the ability to set non-blocking on a
packet-by-packet basis, which is not a very useful thing to have
anyway

if the socket is blocking then the code already adds MSG_WAITALL, so
MSG_DONTWAIT is also not needed in that case.

9d055846f2 r3278: - rewrote the client side rpc connection code to use lib/socket/
rather than doing everything itself. This greatly simplifies the
  code, although I really don't like the socket_recv() interface (it
  always allocates memory for you, which means an extra memcpy in this
  code)

- fixed several bugs in the socket_ipv4.c code, in particular client
  side code used a non-blocking connect but didn't handle EINPROGRESS,
  so it had no chance of working. Also fixed the error codes, using
  map_nt_error_from_unix()

- cleaned up and expanded map_nt_error_from_unix()

- changed interpret_addr2() to not take a mem_ctx. It makes absolutely
  no sense to allocate a fixed size 4 byte structure like this. Dozens
  of places in the code were also using interpret_addr2() incorrectly
  (precisely because the allocation made no sense)

5b44130afa r2671: we're getting too many errors caused by the talloc_realloc() API not
taking a context (so when you pass a NULL pointer you end up with
memory in a top level context). Fixed it by changing the API to take a
context. The context is only used if the pointer you are reallocing is
NULL.

fe45888e22 r2581: added "hosts allow" and "hosts deny" checking in smbd. I needed this
as my box keeps getting hit by viruses spreading on my companies
internal network, which screws up my debug log badly (sigh).

metze, I'm not sure if you think access.c should go in the socket
library or not. It is closely tied to the socket functions, but you
may prefer it separate.

The access.c code is a port from Samba3, but with some cleanups to
make it (slighly) less ugly.
