- rename "lib_ctx" to "mac_implementation" which is what is stored because
of previous commit
- rename "mac" to "mac_context" to be clearer with what is stored in this
variable too
The main work of this commit is to rewrite cipher_aes_128_cbc_cmac()
which was too slow and created issues when running the 4G eNB on some
machines (LLL when using a b210).
Instead of creating the security context, use it, and delete it, all in
cipher_aes_128_cbc_cmac(), we introduce the function init_aes_128_cbc_cmac()
to create it, and we change cipher_aes_128_cbc_cmac() to just use it,
and we also adapt free_aes_128_cbc_cmac(). The function aes_128_cbc_cmac()
is removed, it does not follow the new init/use/free API.
Doing so, on the primary test machine used to do this work (a powerful
and fast machine where it is possible to set the CPUs' frequencies)
it was possible to limit the CPUs' frequencies to 500 MHz (it was not
possible to go lower) without any LLL (using a b210, quectel UE in
idle, no data traffic, only periodic measurement reports). Before this
commit, it was necessary to set a frequency of at least 1.8 GHz
otherwise some LLL would appear.
Then we need to adapt the rest of the code to take into account those
changes.
A notion of security container (stream_security_container_t) containing
ciphering and integrity contexts is introduced.
And the code is harmonized for, hopefully, better readability.
The (opaque) type stream_security_context_t is introduced, used by
both integrity and ciphering contexts. The idea is to use a
init()/use()/free() API for all the security procedures, identical for
all the ciphering and integrity procedures.

After the recent update of matix, collected logs contain color codes
and we did not find the way to switch them completely off.
Replacement of "docker compose logs" by "docker logs" resolves this
issue. This commit includes changes related to "docker logs" usage.
Reset all the circular buffer to zero; this ensures that we cannot read
uninitialized data. Since this is RFsimulator, performance is not a
problem here either (and zeroing out happens only once).
Memsan complains that uninitialized reads originate because of these
warnings. Most of the corresponding variables are actually read into
through by libconfig; nevertheless, initializing them should not have a
bad side-effect (because the initialized value is overwritten).
We access G_N at indexes that are not necessarily 32-byte aligned,
leading to segfaults. Use simde_mm256_loadu_si256() to load from memory
at an unaligned memory address to avoid the segfault.
Discovered using clang; it is unclear why gcc did not encounter the same
segfault.
-rdynamic is necessary for clang as well to properly link shared
executables. Add furthermore an option to ignore unused command line
arguments, to suppress warning
clang: warning: argument unused during compilation: '-rdynamic' [-Wunused-command-line-argument]
This is likely because -rdynamic is only relevant for the linker, but
the corresponding option add_link_options() is only available starting
cmake 3.13, while we are still at 3.12 (for Ubuntu 18, to my
understanding).

Unlike the previous commit, in noS1, we cannot use Attach(), as noS1
automatically brings up an interface, no matter whether the connection
succeeded or not. Therefore, consistently wait a bit longer to increase
the chance that the radio is really up.
For various reasons, the UE might take longer to connect to the eNB. A
simple sleep might not be enough; instead, use Attach() to actively wait
that the UE gets an IP address. The added bonus of this function is that
it will also stop&restart a UE if it did not attach, i.e., it will try
multiple times to attach the UE.
The code (author) confused MCE_PARAMS_DESC and MCE_NETPARAMS_DESC and
tried to read the MCE name from MCE_NETPARAMS_DESC when in reality it
should come from MCE_PARAMS_DESC. This commit fixes to use the right
array.
In a previous commit, the functionality of handling IPv6 (and DNS names)
as part of the IPv4 was introduced (in IPv4 field for backwards
compatibility). This commit now removes superfluous configuration
fields:
- IPv6: handled by IPv4 field
- active: users can just remove an entry
- preference: not needed
- Update the configuration for benetel 650 and 550 for new firmware version
- Remove the old firmware configuration file and description in the document
- Add a new RU configuration section
- Add How to get support from the OAI Community to clarify the support procedure.
Rewrite sctp_create_new_listener() to use getaddrinfo() to look up
IPv4/IPv6 addresses via a common interface. This allows to use e.g. DNS,
and enables the SCTP library to listen on IPv6 ports.
To support the above, the corresponding message is changed to not take
an IPv4 address on 4 bytes (and separate IPv6), but a single name that
will be resolved via getaddrinfo()
The previous init message used to allow multiple IPv4/IPv6 addresses;
since this is not used anywhere, remove the corresponding functionality.
Modify all uses of this ITTI message to copy te SCTP init bind addr into
ITTI message.
Use getaddrinfo() to look up IP (v4/v6) addresses. The old
interface of separately specifying IPv4 and IPv6 addresses is
preserved, but both fields allow to specify types of addresses, and we
will remove one field in the future.
