<p> By default <c>global</c> does <i>not</i> take any
62+
actions to restore a fully connected network when
63+
connections are lost due to network issues. This is
64+
problematic for all applications expecting a fully
65+
connected network to be provided, such as for example
66+
<c>mnesia</c>, but also for <c>global</c> itself. A
67+
network of overlapping partitions might cause the
68+
internal state of <c>global</c> to become inconsistent.
69+
Such an inconsistency can remain even after such
70+
partitions have been brought together to form a fully
71+
connected network again. The effect on other applications
72+
that expects that a fully connected network is maintained
73+
may vary, but they might misbehave in very subtle hard to
74+
detect ways during such a partitioning. </p> <p> In order
75+
to prevent such issues, we have introduced a <i>prevent
76+
overlapping partitions</i> fix which can be enabled using
77+
the <seeapp
78+
marker="kernel:kernel_app#prevent_overlapping_partitions"><c>prevent_overlapping_partitions</c></seeapp>
79+
<c>kernel(6)</c> parameter. When this fix has been
80+
enabled, <c>global</c> will actively disconnect from
81+
nodes that reports that they have lost connections to
82+
other nodes. This will cause fully connected partitions
83+
to form instead of leaving the network in a state with
84+
overlapping partitions. Note that this fix <i>has</i> to
85+
be enabled on <i>all</i> nodes in the network in order to
86+
work properly. Since this quite substantially changes the
87+
behavior, this fix is currently disabled by default.
88+
Since you might get hard to detect issues without this
89+
fix you are, however, <i>strongly</i> advised to enable
90+
this fix in order to avoid issues such as the ones
91+
described above. As of OTP 25 this fix will become
92+
enabled by default. </p>

The crypto app in OTP can since OTP-24.2 be compiled,
41+
linked and used with the new OpenSSL 3.0 cryptolib.</p>
42+
<p>
43+
The crypto app has 3.0 support has been improved, but is
44+
still <em>*not recommended*</em> for other usages than
45+
experiments and alpha testing. There are not yet any
46+
guaranties that it works, not even together with other
47+
OTP applications like for example SSL and SSH, although
48+
there are no known errors.</p>
49+
<p>
50+
Since the previous release, OTP-24.2, the following
51+
improvements have been done:</p>
52+
<p>
53+
- It has been tested during nearly every nightly test on
54+
the OTP lab</p>
55+
<p>
56+
- The hash algorithms <c>md4</c> and <c>ripemd160</c>
57+
have been enabled with OpenSSL 3.0.</p>
58+
<p>
59+
- The ciphers <c>blowfish_cbc</c>, <c>blowfish_ecb</c>,
60+
<c>des_cbc</c>, <c>des_cfb</c>, <c>des_ecb</c>,
61+
<c>rc2_cbc</c> and <c>rc4</c> have been enabled with
62+
OpenSSL 3.0.</p>
63+
<p>
64+
Disabled or unsupported with OpenSSL 3.0 are still:</p>
65+
<p>
66+
- ENGINE support</p>
67+
<p>
68+
- FIPS mode</p>
69+
<p>
70+
- Other providers than the built-in ones</p>
71+
<p>
72+
- Compiling and linking with OpenSSL 3.0 cryptolib in
73+
compatibility modes (for example to behave as 1.1.1) </p>
74+
<p>
75+
and, the ciphers <c>blowfish_cfb64</c> and
76+
<c>blowfish_ofb64</c> are not supported and will not be
77+
either.</p>
78+
<p>
79+
Deprecated functions in the OpenSSL 3.0 cryptolib must
80+
not be disabled as OTP/crypto still uses some of the
81+
deprecated API functions. The gcc flag
82+
<c>-Wno-deprecated-declarations</c> is set to prevent
83+
deprecation warnings to be printed when compiling.</p>

New configure option ( <c>--disable-otp-test-engine</c>)
96+
to prohibit the build of the OTP test engine used in some
97+
test suites.</p>
98+
<p>
99+
The reason is that the test engine could be hard to
100+
compile on for instance LibreSSL 3.5.0. For that
101+
particular cryptolib version (or higher), this configure
102+
option is set automatically.</p>
