TDB2 started with a top-level hash of 1024 entries, divided into 128
groups of 8 buckets. When a bucket filled, the 8 bucket group
expanded into pointers into 8 new 64-entry hash tables. When these
filled, they expanded in turn, etc.
It's a nice idea to automatically expand the hash tables, but it
doesn't pay off. Remove it for NTDB.
1) It only beats TDB performance when the database is huge and the
TDB hashsize is small. We are about 20% slower on medium-size
databases (1000 to 10000 records), worse on really small ones.
2) Since we're 64 bits, our hash tables are already twice as expensive
as TDB.
3) Since our hash function is good, it means that all groups tend to
fill at the same time, meaning the hash enlarges by a factor of 128
all at once, leading to a very large database at that point.
4) Our efficiency would improve if we enlarged the top level, but
that makes our minimum db size even worse: it's already over 8k,
and jumps to 1M after about 1000 entries!
5) Making the sub group size larger gives a shallower tree, which
performs better, but makes the "hash explosion" problem worse.
6) The code is complicated, having to handle delete and reshuffling
groups of hash buckets, and expansion of buckets.
7) We have to handle the case where all the records somehow end up with
the same hash value, which requires special code to chain records for
that case.
On the other hand, it would be nice if we didn't degrade as badly as
TDB does when the hash chains get long.
This patch removes the hash-growing code, but instead of chaining like
TDB does when a bucket fills, we point the bucket to an array of
record pointers. Since each on-disk NTDB pointer contains some hash
bits from the record (we steal the upper 8 bits of the offset), 99.5%
of the time we don't need to load the record to determine if it
matches. This makes an array of offsets much more cache-friendly than
a linked list.
Here are the times (in ns) for tdb_store of N records, tdb_store of N
records the second time, and a fetch of all N records. I've also
included the final database size and the smbtorture local.[n]tdb_speed
results.
Benchmark details:
1) Compiled with -O2.
2) assert() was disabled in TDB2 and NTDB.
3) The "optimize fetch" patch was applied to NTDB.
10 runs, using tmpfs (otherwise massive swapping as db hits ~30M,
despite plenty of RAM).

Analysis:
1) TDB wins on small databases, beating TDB2 by ~15%, NTDB by ~10%.
2) TDB starts to lose when hash chains get 10 long (fetch 10% slower
than TDB2/NTDB).
3) TDB does horribly when hash chains get 100 long (fetch 4x slower
than NTDB, 5x slower than TDB2, insert about 2-3x slower).
4) TDB2 databases are 40% larger than TDB1. NTDB is about 15% larger
than TDB1
This is designed to allow us to make ntdb_context (and NTDB_DATA returned
from ntdb_fetch) a talloc pointer. But it can also be used for any other
alternate allocator.

TDB allows this for internal databases, but it's a bad idea, since the
name is useful for logging.

The performance numbers for transaction pagesize are indeterminate:
larger pagesizes means a smaller transaction array, and a better
chance of having a contiguous record (more efficient for
ntdb_parse_record and some internal operations inside a transaction).
On the other hand, large pagesize means more I/O even if we change a
few bytes.
But it also controls the multiple by which we will enlarge the file,
and hence the minimum db size. It's 4k for tdb1, but 16k seems
reasonable in these modern times.

Now our database is always a multiple of NTDB_PGSIZE, we can remove the
special handling for the last block.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
As copied from tdb1, there is logic in the transaction code to handle
a non-PGSIZE multiple db, but in fact this only happens for a
completely unused database: as soon as we add anything to it, it is
expanded to a NTDB_PGSIZE multiple.
If we create the database with a free record which pads it out to
NTDB_PGSIZE, we can remove this last-page-is-different logic.
Of course, the fake ntdbs we create in our tests now also need to be
multiples of NTDB_PGSIZE, so we change some numbers there too.

ntdb uses tdb's transaction code, and it has an undocumented but implicit
assumption: that the transaction recovery area is always aligned to the
transaction pagesize. This means that no block will overlap the recovery
area.
This is maintained by rounding the size of the database up, so do the same
for ntdb.

This simplifies our supported configurations down to those that we test and expect
to work. security=domain and domain logons = yes has never made much sense, and
security=ads and domain logons = yes was only ever used in early experiments for
our AD support using smbd.
The correct way to be an AD DC is to set "server role = active directory domain controller"
Andrew Bartlett
This will allow us to detect from the smb.conf if this is a Samba4 AD
DC which will allow smarter handling of (for example) accidentially
starting smbd rather than samba.
To cope with upgrades from existing Samba4 installs, 'domain
controller' is a synonym of 'active directory domain controller' and
new parameters 'classic primary domain controller' and 'classic backup
domain controller' are added.

After consolidating DNS resolver code to lib/addns, there is one piece
that still needs to be moved into a common DNS resolver library: DNS_HOSTS_FILE
subsystem. Unfortunately, direct move would require lib/addns to depend on
libcli/util/{ntstatus.h,werror.h} (provided by errors subsystem).
In addition, moving libcli/dns/* code to lib/addns/ would make conflicting
the dns_tkey_record struct. The conflict comes from source4/dns_server/ and is due
to use of IDL to define the struct. lib/addns/ library also provides its own definition
so we either need to keep them in sync (rewrite code in lib/addns/ a bit) or
depend on generated IDL headers.
Thus, making a private library and subsystem clidns is an intermediate step
that allows to buy some time fore refactoring.
System MIT krb5 build also enabled by specifying --without-ad-dc
When --with-system-mitkrb5 (or --withou-ad-dc) option is passed to top level
configure in WAF build we are trying to detect and use system-wide MIT krb5
libraries. As result, Samba 4 DC functionality will be disabled due to the fact
that it is currently impossible to implement embedded KDC server with MIT krb5.
Thus, --with-system-mitkrb5/--without-ad-dc build will only produce
* Samba 4 client libraries and their Python bindings
* Samba 3 server (smbd, nmbd, winbindd from source3/)
* Samba 3 client libraries
In addition, Samba 4 DC server-specific tests will not be compiled into smbtorture.
This in particular affects spoolss_win, spoolss_notify, and remote_pac rpc tests.
After migrating to use libaddns, reply_to_addrs() needed to change the
way answers are iterated through. Originally libroken implementation
gave all answers as separate records with last one being explicitly NULL.
libaddns unmarshalling code gives all non-NULL answers and should be
iterated with explicit reply->num_answers in use.
In case krb5_cc_get_lifetime is not available, iterate over
existing tickets in the keytab, find the one marked as TKT_FLAG_INITIAL,
and use its lifetime. This is how it is implemented in Heimdal and
how it was suggested to be done by MIT Kerberos developers.
We need to ifdef out some minor things here because there is no available API
to set these options in MIT.
The realm and canonicalize options should be not interesting in the client
case. Same for the send_to_kdc hacks.
Also the OLD DES3 enctype is not at all interesting. I am not aware that
Windows will ever use DES3 and no modern implementation relies on that enctype
anymore as it has been fully deprecated long ago, so we can simply ignore it.
"security=server" has a lot of problems in the world with
modern security (ntlmv2 and krb5). It was also not very
reliable, as it needed a stable connection to the password
server for the lifetime of the whole client connection!
Please use "security=domain" or "security=ads" is you
authentication against remote servers (domain controllers).
