By using a struct we may have warnings at compilation time in some
cases if the type is not used properly.
The type definition becomes a bit weird, so we need to properly
comment.
If too strange, we can revert to the classical "void" definition.
- 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.
These functions enables (un)deployment of the OAI CN v2.0.1, increase
reliability and speedup overall CN (un)deployment compared to current
implementation.
Use "--wait" helm option to wait for deployment/undeployment of the CN.
Wait for pods to be in a ready state before marking the release as
successful. If not deployed/undeployed before timeout, marked as
unsuccessful.
Hardcode path for OC CN5G deployment/undeployment
- Remove unused AmariUE config file, replace by new one - for PLMN 00102
- Change frequency of AW2S pipeline - Move center frequency by 40 MHz to avoid interferency with other setups
in the lab. Set center frequency to ~ 3450 MHz.
The absslot_tx overflow issue observed during integration testing of AW2S
RU with GPS as the source for the clock synchronization. Causes the gNB
not to start the TX thread and stops the processing.

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).
