remove un-necessary global variables
Remove global variables that can be removed by a trivial way:
- simply dead globals
- or reference is a single source, so can be static
setting them static reduces the scope, that is a progress, but of course as
for all static variables, the code is still not re-entrant
* ideally the result of these macros shall be relevant
only in unit tests, in order to validate enc/dec NAS functions
* use a local print macro
* remove dependency from LOG module
* simplified the code
* cleanup TLVDecoder.c (kept it for LTE dependencies)
* FGMM enc/dec library files
* Plain message encoding + logic for security protected message
* added fill_fgstmsi function
* add checks on length in 5G-S-TMSI encoder function
* encoding of NAS Service Request and relevant mandatory IEs
Fix Regression 4G
- Fix various bugs and/or regressions in 4G code
- Also, the CI does not test RFsim 4G with --sanitize, enables this to
detect problems.
Simplify logs in gNB&UE
- reduce the amount of printf() that outputs useless info
- in MAC, PHY, NGAP, RRC, mark some "important" UE events with LOG_A for
better visibility -> can put log_config.global_log_level analysis to
only see important stuff
- in RRC, use some macro to consistently print logs
- track the cellID of a UE in RRC
* DL NAS Transport messages can piggy-back 5GSM messages
* the relevant decoding functions can be called in the handler (e.g. capture_pdu_session_establishment_accept_msg)
* the capture_pdu_session_establishment_accept_msg function is already handling
the code in the case FGS_PDU_SESSION_ESTABLISHMENT_ACC of NAS_DOWNLINK_DATA_IND
Closes: #841
The IES_DECODE_U16 macro loads a 16 bit integer from an arbitrary
address; this can lead to reads from misaligned addresses, and undefined
behavior sanitizer warns, like, e.g., so:
openair3/NAS/COMMON/IES/ProtocolConfigurationOptions.c:62:5: runtime error: load of misaligned address 0x7f3c24032c01 for type 'uint16_t', which requires 2 byte alignment
To fix this, first use memcpy() to load to a 16-bit aligned address,
then do the actual decoding.
- rename as_nas_info_t member data to nas_data to have a uniq name to
trace between complex malloc/free of this pointer
- fix, maybe not perfect, these pais od malloc/free
- remove typedef name changes across transmission of these as_nas_info_t
over itti, as name changing makes it even more confusing
- remove globals that are likely possible races
- in as_message_decode() fix memcpy size, it is hard to understand the
initial idea, likely the author beleives a struct of struct makes a
intermediate pointer
- in network_api.c remove globals (static but used globally)
- remove casts that are there to hide gcc warnings on probable unaligned
access
- remain a weird mix of packed/unpacked versions of the same typedef,
but gcc is happy
The previously used net_ip_address_t type is limited to some bytes, but
the CU name might be longer. Use char * to allow longer DNS names.
Also, this type separates IPv4/v6, which is not necessary, as it is now
handled by the same C API (getaddrinfo()), since !2635.

User of the SCTP module use the assoc_id for connection identification.
The previous code set the assoc_id to -1, so there is no way of telling
which connection broke. Use the assoc_id instead

Before this commit, the following will trigger a complete rebuild:
- create another git name (git checkout -b test)
- run cmake again manually (cmake ..)
- run ninja again
The top-level CMakeLists.txt uses add_definitions() to add git
information to all targets; if some git information changes, this will
mark all command lines as dirty, triggering the build.
There is an easy solution: instead of passing this information on the
command line, pass it in a header. This commit uses configure_file() to
generate a file oai_version.h in the build directory with the same
information. Various sources files, e.g., main executables, use this to
output the same information as before. It is then also not necessary to
use header guards, as cmake takes care to create this file.
If cmake is re-run, it will update the header, and trigger only files
including this header will be rebuilt (which can be shown with the above
stpes). The information passed is the same as before, and updates the
information when the old method would have updated it.
