<c>node_org_enc</c>) in order to be backward compatible

<p>
ei: integer overflow in string/atom encoding</p>
<p>
ei_encode_atom() and ei_encode_string() use strlen() to
get the length of the buffer. As strlen() returns an
unsigned long long and both ei functions take a signed
integer, the length fields may overflow.</p>
<p>
Check so that the results of strlen can be held in a
signed integer. (Thanks to Michael Santos)</p>

<p>
Fix using sizeof() for array given as function argument</p>
<p>
When using the sizeof() operator for an array given as
function argument it returns the size of the pointer. In
this case, the affected function hex(char digest[16],
char buff[33]) will just print 4 or 8 byte instead of the
full length of 16 bytes, on 32bit and 64bit systems
respectively. (Thanks to Cristian greco)</p>

ei_gethostbyname directly since gethostbyname supports
IPv4 addresses.</p>

<p>compact IEEE 754 double encoding in external binary
format for ei</p> <list><item><p>Implement the compact
IEEE 754 double encoding in external binary format for
ei. Encoding for ei now always produces the NEW_FLOAT_EXT
format. Decoding and term printing handle both the old
ERL_FLOAT_EXT encoding and the new NEW_FLOAT_EXT
encoding. </p></item> <item><p>Legacy erl_interface code
also handles the new encoding, but still produces the
ERL_FLOAT_EXT encoding by default.</p></item>
<item><p>Also enable the DFLAG_NEW_FLOATS distribution
flag.</p></item> <item><p>ei_get_type() will return
ERL_FLOAT_EXT regardless if the external format is
encoded with ERL_FLOAT_EXT or NEW_FLOAT_EXT for
doubles.</p></item> <item><p>Reduce the number of copies
of the code for encoding and decoding doubles throughout
ei and erl_interface by instead calling the ei encoding
and decoding functions wherever possible.</p></item>
<item><p>Restore commented-out float tests in
ei_decode_SUITE and ei_encode_SUITE in
lib/erl_interface/test. Modify them to make them match
the style of other tests in the same suites.</p></item>
</list> <p>These changes are based on an ei float patch
from Serge Aleynikov originally submitted against R12B-2
in July 2008 and reworked by Steve Vinoski May 2010.</p>

Document debug support.</p>
<p>
Debug trace output for connection activity could be
enabled setting the trace level as an integer to the
EI_TRACELEVEL environment variable. This option could
also be read and set from a running program using
ei_get_tracelevel(void) and ei_set_tracelevel(int).</p>

<p>Cross compilation improvements and other build system
improvements.</p>
<p>Most notable:</p> <list><item> Lots of cross
compilation improvements. The old cross compilation
support was more or less non-existing as well as broken.
Please, note that the cross compilation support should
still be considered as experimental. Also note that old
cross compilation configurations cannot be used without
modifications. For more information on cross compiling
Erlang/OTP see the <c>$ERL_TOP/INSTALL-CROSS.md</c> file.
</item><item> Support for staged install using <url
href="http://www.gnu.org/prep/standards/html_node/DESTDIR.html">DESTDIR</url>.
The old broken <c>INSTALL_PREFIX</c> has also been fixed.
For more information see the <c>$ERL_TOP/INSTALL.md</c>
file. </item><item> Documentation of the <c>release</c>
target of the top <c>Makefile</c>. For more information
see the <c>$ERL_TOP/INSTALL.md</c> file. </item><item>
<c>make install</c> now by default creates relative
symbolic links instead of absolute ones. For more
information see the <c>$ERL_TOP/INSTALL.md</c> file.
</item><item> <c>$ERL_TOP/configure --help=recursive</c>
now works and prints help for all applications with
<c>configure</c> scripts. </item><item> Doing <c>make
install</c>, or <c>make release</c> directly after
<c>make all</c> no longer triggers miscellaneous
rebuilds. </item><item> Existing bootstrap system is now
used when doing <c>make install</c>, or <c>make
release</c> without a preceding <c>make all</c>.
</item><item> The <c>crypto</c> and <c>ssl</c>
applications use the same runtime library path when
dynamically linking against <c>libssl.so</c> and
<c>libcrypto.so</c>. The runtime library search path has
also been extended. </item><item> The <c>configure</c>
scripts of <c>erl_interface</c> and <c>odbc</c> now
search for thread libraries and thread library quirks the
same way as <c>erts</c> do. </item><item> The
<c>configure</c> script of the <c>odbc</c> application
now also looks for odbc libraries in <c>lib64</c> and
<c>lib/64</c> directories when building on a 64-bit
system. </item><item> The <c>config.h.in</c> file in the
<c>erl_interface</c> application is now automatically
generated in instead of statically updated which reduces
the risk of <c>configure</c> tests without any effect.

In <c>ei_decode_term.c</c> when decoding a double

the first 3 bytes are read, but the index did not
increment by the total size.</p>

In <c>ei_decode_fun.c</c> no check of correct buffer
allocation or data length was done.</p>

<p>Process identifiers and port identifiers have been
made more unique. Previously 18 bits were used as id in
the internal representation of process and port
identifiers. Now 28 bits are used. </p>
<p>The maximum
limit on the number of concurrently existing processes
due to the representation of pids has been increased to
268435456 processes. The same is true for ports. This
limit will at least on a 32-bit architecture be
impossible to reach due to memory shortage. </p>
<p><em>NOTE:</em> By default, the <c><![CDATA[ERTS]]></c>, and the
<c><![CDATA[erl_interface]]></c>, <c><![CDATA[ei]]></c>, and <c><![CDATA[jinterface]]></c>
libraries are now only guaranteed to be compatible with
other Erlang/OTP components from the same release. It is
possible to set each component in compatibility mode of
an earlier release, though. See the documentation for
respective component on how to set it in compatibility
mode. </p>
