Rely on /dev/urandom

2015-10-13T02:25:38+00:00

This removes quite a bit of code. All reasonable systems have /dev/urandom
these days. Linux, Solaris and the BSDs do.  In case we find a system
without /dev/urandom, we will have to go hunting in other libraries.

The main reason for this is speed: On Ubuntu 14.04 doing direct reads from
/dev/urandom is 2-3 times faster than our md4 based code. On virtualized
FreeBSD 10 the difference is even larger.

My first approach was to use fopen/fread. It was even faster, but less
than twice as fast. So I thought we could save the additional complexity
when having to deal with throwing away buffers when forking and the
additional memory footprint per process.

With this simple generate_random_buffer it will be easier to adapt new
syscalls to get randomness.

tdb_wrap: Move to specific directory.

2012-03-10T22:13:01+00:00

It's a bit confusing to mix low-level and high-level libraries.  We had
multiple libraries in one directory, and there were have circular
dependencies with other libraries outside that directory (in this case,
samba-hostconfig).

lib/util: Add back control of mmap and hash size in tdb for top level build

2011-10-13T12:06:07+00:00

This passes down a struct loadparm_context to allow these
parameters to be checked.  This may be s3 or s4 context, allowing the
#if _SAMBA_BUILD_ macro to go away safely.

s4-param Remove 'secrets database' parameter

2011-06-06T05:02:39+00:00

This is now just secrets.ldb in the private dir, which remains.

lib/util Move source3 tdb_wrap_open() into the common code.

2011-05-06T05:51:24+00:00

This #if _SAMBA_BUILD == 3 is very unfortunate, as it means that in
the top level build, these options are not available for these
databases.  However, having two different tdb_wrap lists is a worse
fate, so this will do for now.

s4-param Rename secrets_init() -> randseed_init()

2011-05-03T05:37:07+00:00

This only sets up the random number generator callback these days, so
use a different database for that.

(All secrets data in Samba4 is in secrets.ldb)
