2082c0c3b5 lib/util: Avoid splitting tevent-unix-util as public library
BUG: https://bugzilla.samba.org/show_bug.cgi?id=11946

Commit 670db6ac1d split tevent-util public
library to create tevent-unix-util public library for standalone ctdb
use.  This created a public library dependency between samba and ctdb
for packaging.

Bundle tevent_unix.c in public library tevent-util as before.  However,
to avoid the dependencies for packaging, standalone ctdb build will
build tevent-util as a private library with only tevent_unix.c

This simplifies any new subsystems (or libraries) which need tevent-util
and are linked in both samba and ctdb.

88be24c279 util/attr.h: use HAVE___ATTRIBUTE__, not __GNUC__ comparisons
The comparisons that look like

    #if (__GNUC__ >= 3) && (__GNUC_MINOR__ >= 1 )

fail if __GNUC_MINOR__ is 0.  The intended comparison is something
more like

    #if __GNUC__ > 3 || (__GNUC__ == 3 && __GNUC_MINOR__ >= 1)

However, given that:

 * these checks are really trying to test the presence of
   __attribute__,

 * there are now credible compilers that are not GCC, which have
   __attribute__ but might not be good at emulating __GNUC__
   numbers, and

 * we really face little risk of running into GCC 2.95

 * we have a HAVE___ATTRIBUTE__ check in ./configure

let's not do the version comparisons.

(Untested on GCC 2.95, GCC 3.0 and GCC 3.1).

5235f1facf util/binsearch: macro for greater than or equal search
Sometimes you want to find the place where an item would be in a
sorted list, whether or not it is actually there.

The BINARY_ARRAY_SEARCH_GTE macro takes an extra 'next' pointer
argument over the other binsearch macros. This will end up pointing to
the next element in the case where there is not an exact match, or
NULL when there is. That is, searching the list

     { 2, 3, 4, 4, 9}

with a standard integer compare should give the following results:

search term    *result    *next
         1      -          2
         3      3          -
         4      4 [1]      -
         7      -          9
         9      9          -
        10      -          - [2]

Notes
[1] There are two fours, but you will always get the first one.
[2] The both NULL case means the search term is beyond the last list
item.

You can safely use the same pointer for both 'result' and 'next', if
you don't care to distinguish between the 'greater-than' and 'equals'
cases.

There is a torture test for this.

The intention of strv_addn() is to be able to add some number of

assumes that the old _strv_append() added the trailing NUL to form a
valid strv.  That's not true.

538d305de9 CVE-2015-5330: next_codepoint_handle_ext: don't short-circuit UTF16 low bytes
UTF16 contains zero bytes when it is encoding ASCII (for example), so we
can't assume the absense of the 0x80 bit means a one byte encoding. No
current callers use UTF16.

ba5dbda6d0 CVE-2015-5330: Fix handling of unicode near string endings
Until now next_codepoint_ext() and next_codepoint_handle_ext() were
using strnlen(str, 5) to determine how much string they should try to
decode. This ended up looking past the end of the string when it was not
null terminated and the final character looked like a multi-byte encoding.
The fix is to let the caller say how long the string can be.

e73ccc06ef Rely on /dev/urandom
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.

22c5699751 lib: Fix server_id_db_set_exclusive
For server_id_db_set_exclusive we need to store the unique id along
with the vnn:pid combo. I had tested all this just with some
smbtorture and net command tests, all of which have a unique id of
zero. When trying to exclusively register "notify-daemon" when smbd
is running, this fails because serverid_exists only tests with zero
unique id. notifyd does have a non-zero unique id, so server_id_exists
will think the existing notifyd is another non-samba process that
happened to claim notifyd's pid.

a4f64500a5 lib: Fix server_id_from_string
sscanf overwrites vars as numbers come in. So the first sscanf will
overwrite "vnn", although it can't scan the whole thing. This leads
to the string "1234" return .vnn=1234, pid=1234. Bad.

While there, save the temp variables. The SCNu32/64 thingies look
ugly, but it's actually c99.
