d1291dacbd r8408: its quite common in our code to free up a connection when we get an
error, but sometimes a socket option may then happen on the NULL
socket. This has been handled by the individual libraries up to now,
but its cleaner to centralise it here

bab977dad7 r7626: a new ldap client library. Main features are:
- hooked into events system, so requests can be truly async and won't
   interfere with other processing happening at the same time

 - uses NTSTATUS codes for errors (previously errors were mostly
   ignored). In a similar fashion to the DOS error handling, I have
   reserved a range of the NTSTATUS code 32 bit space for LDAP error
   codes, so a function can return a LDAP error code in a NTSTATUS

 - much cleaner packet handling

1692bbf2e2 r7227: added a socket_pending() call to abstract away the FIONREAD ioctl. It
will be interesting to see if this causes any portability problems, as
it is a less commonly used call.

e82aad1ce3 r5298: - got rid of pstring.h from includes.h. This at least makes it a bit
less likely that anyone will use pstring for new code

 - got rid of winbind_client.h from includes.h. This one triggered a
   huge change, as winbind_client.h was including system/filesys.h and
   defining the old uint32 and uint16 types, as well as its own
   pstring and fstring.

8783aa8ea5 r4831: added udp support to our generic sockets library.
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,
LOCAL-SOCKET

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

0caeda53d3 r3356: in the standard process model we need to make sure we close all
listening sockets after the fork to prevent the child still listening
on incoming requests.

I have also added an optimisation where we use dup()/close() to lower
the file descriptor number of the new socket to the lowest possible
after closing our listening sockets. This keeps the max fd num passed
to select() low, which makes a difference to the speed of select().

8c752ec861 r3318: generate random STATUS_MORE_ENTRIES errors (1 in 10 packets) as well

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.

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)

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.
