This avoids getting IPv4 addresses as mapped IPv6 addresses
(e.g. ::ffff:192.168.0.1).
Before the bahavior was inconsistent between operating system
and distributions. Some system have IPV6_ONLY as default.
Now we consistently get AF_INET for IPv4 addresses and AF_INET6
for IPv6 addresses.
It also makes it possible to listen only on IPv6 now
as "::" doesn't imply "0.0.0.0" anymore. Which also
avoids confusing log messages that we were not able to
bind to "0.0.0.0".

Most fault codes have a NTSTATUS representation, so use that.
This brings the fault handling in common with the source4/librpc/rpc code,
which make it possible to share more highlevel code, between source3 and
source4 as the error checking can be the same now.

This is now API compatible with the existing code in lib/util/charset
lazy_initialize_conv() is no longer called as init_iconv() is called
when the smb.conf is processed, and get_conv_handle() will auto-init
with defaults if required.
load_case_tables_library() is no longer requried as all binaries and
libraries already load these in their entry points, as otherwise all
the other string functions would fail.

The s4 implementation didn't do multibyte strings, so was only good
for '/' which is known to be safe in all multibyte charsets.

This means that there is no need for the 'valid.dat' table to be
loaded by anything other than smbd, so the unloader is also removed.
The concept of a 'valid dos character' has been replaced by the hash2

This way, the record will be scheduled for fast vacuuming.
This is sent with the NOREPLY flag, so ctd should not sent
a reply packet and samba does not expect one. Hence, it
is not important for the success of the db_ctdb_delete command
whether or not the ctdbd we are running against supports the
SCHEDULE_FOR_DELETION control.
The only flag that is currently used is the NOREPLY flag to indicate that
the client expects no reply packet. This needs to get passed down to the
ctdb daemon so that it really does not send a reply.
Makes these interfaces much harder to misuse and easier to ensure error
checking.

This reverts a part of 0189087e25. That one might have fixed the fast path,
but it broke the slow path. convert_string_internal returns 0/-1 despite the
size_t result type and the misleading comment. If you follow the path to
smb_iconv and for example iconv_copy(), you will see that this routine returns
0 even after it copied something.
How to check: Use German locale, and do an smbclient "allinfo" on a file
modified in march (März in German). Notice the "ä". Before 0189087 this printed
correctly, after 0189087 it cut off the fields after the M for März.

As discovered by David Disseldorp <ddiss@suse.de>, convert_string_talloc()
doesn't always return consistent results for a zero length string. The
API states an incoming string must *always* contain the terminating null,
but unfotunately too much code expects passing in a zero source length
to return a null terminated string, so at least ensure we return a
correct null string in the required character set and return the
correct length.
Also ensure we cannot return a zero length for a converted string
(we ensure that the returned buffer is always allocated and zero
terminated anyway) as calling code depends on the fact that returning
true from this function will *always* return a non-zero length (as
it must include the terminating null).

Pair-Programmed-With: Andrew Bartlett <abartlet@samba.org>
When doing a non-locking fetch on a record of a persistent db when no
transaction is running, the old behaviour was to fetch locally and
do a ctdb call when the record was not found in the local db.
The call is useless for persistent dbs anyway since they are only
written to using transactions and hence kept in sync, but it is
also harmful, because a ctdb call will bump the record RSN when it
does actually migrate the record from one node to another.
Recently, ctdb has been changed to make all calls do a migration.
This uncovered the client misbehaviour for persistent dbs, because
now _each_ non-locking fetch will render the persistent db inconsistent:
A subsequent transaction which touches the record in question will
fail because the RSNs are out of sync.
This patch fixes this old bug.

If IPv6 DNS names are turned on, but Samba isn't configured to
listen on an IPv6 interface, then is_myname_or_ipaddr() can return
false on a valid DNS name that it should detect is our own. If the
IPv6 addr is returned by preference, then looking at the first addr
only causes is_myname_or_ipaddr() to fail. We need to look at all the
addresses returned by the DNS lookup and check all of them against
our interface list. This is an order N^2 lookup, but there shouldn't
be enough addresses to make this a practical problem.

This code wrote to the full buffer in fstrcpy(), pstrcpy() and other
fixed-length string manipulation functions.
The hope of this code was to find out at run time if we were mixing up
pstring and fstring etc, and to record where this came from. It has a
runtime performance impact (particularly if compiled with
--enable-developer).
It is being removed because of the complexity it adds, and the
distinct lack of bugs that this complexity has been credited in
finding.
The macro-based compile-time checking of string sizes remains.

A callback of tldap_search_send might not interested in the rest of the results
and could do a TALLOC_FREE of the search request. In this case, "subreq" is

When pulling non-aligned ucs2 strings, we neglected to add in the
pad byte to the buffer length we've eaten. This caused the device

This is the s3 debug system, with a number of changes to tidy it up
for common use. The debug class system is simplified by the removal of the
ISSET table, the system no longer attempts to cope with assignment of
DEBUGLEVEL, and the full class table is always available (rather than
just DEBUGLEVEL_CLASS[DBCG_ALL]) from startup. It is also no longer
confusingly described as a hack, but as the initial table.

These variables, of type struct auth_serversupplied_info were poorly
named when added into 2001, and in good consistant practice, this has
extended all over the codebase in the years since.
The structure is also not ideal for it's current purpose. Originally
intended to convey the results of the authentication modules, it
really describes all the essential attributes of a session. This
rename will reduce the volume of a future patch to replaced these with
a struct auth_session_info, with auth_serversupplied_info confined to
the lower levels of the auth subsystem, and then eliminated.
(The new structure will be the output of create_local_token(), and the
change in struct definition will ensure that this is always run, populating
local groups and privileges).

These now call the common _m functions that consider UTF16 code points.
This removes the code which will make up a 'lame' table in memory, as
this can just as correctly be handled by running the algorithm at runtime (which is to call toupper() and tolower() on characters < 128).
When used, a top level waf build will always locate the correct table
- in the build tree or outside - due to relinking the installed
binary.

Via an AF_NETLINK socket, the Linux kernel can inform us when IP addresses are
added or dropped.
This will first be used in winbind, it was triggered by clustering with ctdb.
When winbind is connected to a domain controller and ctdb decides to move away
the IP address that winbind used locally for the connection to the DC, the next
request will run into a timeout. winbind sends out its request, but the
response will never arrive: The IP is gone.
It will also be interesting for more reliable online/offline detection, but
this is something for future winbind refactoring.

If select returns EBADF (which should NEVER happen), then we loop infinitely
because the select masks seem all active.
I've been given an strace where smbd floods syslog with inotify-related

the inotify event callback. It then complains there's no data on the inotify
fd.

In the cluster case it can happen that a node just died and we did not yet have
the time to clean up serverid.tdb. If the corresponding serverid.tdb record
that represented a process was migrated away from the dead record, it
represents existence of a process where it is already dead.
