We use the same resource for CSI meas report and RSRP (judging by the
name of the functions), but the memory allocations need to be separate
to avoid a double free:

During refactoring, I had asan errors in the next line. It took me some
time to figure out that a DRB ID 0 is not valid (cf.
get_next_available_drb_id() and get_drb(), they enforce this).

Move the filling of DRBs to set up for UE context setup/modification
request into the corresponding functions, and use malloc() deliberately
to avoid memory leaks. In fact fill_drb_to_be_setup_from_e1_resp()
allocates memory dynamically (and has to do that), so the easiest is to
do the same for DRBs. The most straight-forward way seems to be to then
dynamically allocate all memory for F1 UE context setup/modification
request messages, and free with the corresponding free functions,
which removes a couple of memory leaks.
Similarly to the commit "Use F1 UE context setup/modif Request in
stack", we do both UE context setup/modification response at once
because of some functions that are shared by the MAC message handler.
Use the new, tested F1 UE context setup request and modification
requests in the stack.
We have to do both at once, because there are some functions that are
used by handlers for both messages, notably
- handle_ue_context_drbs_setup()
- handle_ue_context_srbs_setup()
(+ and some functions called by those two). For instance, the first uses
the (new/old) type f1ap_drb_to_be_setup_t/f1ap_drb_to_setup_t which is
shared. The alternative would be to duplicate the functionality
temporarily, and I want to avoid unnecessary code churn.
Reintroduce separate message types to simplify the encoding/decoding,
including shorter names. The old types will be removed once everything
has been migrated to the new encoder/decoder, which should ensure that
everything is properly migrated to the unit-tested encoder/decoders.
Also, for each type of F1 message (F1 UE context setup request,
response, modification request, ...) introduce a separate type to avoid
to mistakenly use wrong fields, which can lead to bugs. In this regard,
the DL PDCP SN bit size in the DRB-ToBeSetup list of the UE context
setup request is optional, as it will also be used in the UE context
modification request DRB SetupMod list (which avoids quite some code
duplication). The encoder checks that this IE is present, though.
F1AP_LIB_FIND_IE() is used to look up elements in a list, but was
hitherto hardcoded to use "protocolIEs" as an intermediate struct. A
follow-up commit will use this macro where we don't have protocolIEs,
but "iE_Extensions". Hence, modify to make it work for that case (and
others) as well.
Introduce generic _F1_CHECK_EXP(), which is like the macros for checking
values (_F1_EQ_CHECK_INT() etc). Reuse the same for introducing
_F1_EQ_CHECK_OPTIONAL_IE that will be used to write the check for
optional fields more concisely.
CP_OPT_BYTE_ARRAY() FREE_OPT_BYTE_ARRAY() are macros to wrap handling of
optional byte arrays.
_F1_MALLOC() simplifies allocations and is similar to asn1cCallocOne(),
but provided to avoid confusion (since more than ASN.1 structures will
use it).
All will be used in the following commits.

Fix Msg3 with MAC CE for C-RNTI and RRCReestablishmentComplete
- Only trigger RRCReconfiguration if UE is not performing RRCReestablishment
- The RRCReconfiguration will be triggered by the RRCReestablishmentComplete

it does not need that many
Cleanup PDU Session Handling in RRC/NGAP
Currently, NGAP and RRC share the same structures and responsibilities when
handling PDU Session information: this creates tight coupling, redundancy, and
makes the code harder to maintain.
- NGAP should be responsible only for: Protocol-specific encoding/decoding
(3GPP TS 38.413)
- RRC should own: PDU Session handling and storage in the UE context
This MR is the first step in a broader refactoring of the PDU Session handling
code across NGAP and RRC layers, with the goal of splitting responsibilities
cleanly between both modules.
- Unified gtpu_tunnel_t for tunnel endpoint config (formerly f1u_tunnel_t)
- Refactored and relocated PDU Session struct definitions for better separation
between NGAP and RRC
- Moved pdusession_t for PDU Session handling out of NGAP, now defined and
managed by RRC only
- Defined 3GPP TS 38.413 message-specific structs in NGAP module
- NGAP now decodes NGAP PDU Session Resource Setup/Modify IEs and transfers
decoded data to RRC via ITTI
- Add helper functions to copy from NGAP message to pdusession_t
- Introduced new encoders/decoders/helpers in NGAP for handling PDU Session
Resource Setup/Modify procedures (e.g. decode_pdusession_transfer)
- Migrated to NGAP and removed duplicated logic for QoS information decoding
(fill_qos)
- Improved logging of GTP tunnel info
- Merged redundant functions (f1u_dl_gtp_update and f1u_ul_gtp_update)
- Removed unused code and obsolete types
- do free_func in seq_arr_erase_it on the provided range and updated unit test
- Other fixes and simplifications (e.g. simplified and clarified naming of
tunnel/session parameters and structs)
This cleanup improves code readability, has a high code churn (the deletions are
~159.7% of the insertions) and prepares for better modularity before the
refactoring of PDU Session handling in RRC/NGAP.
Add NAS Authentication Reject enc/dec library and unit test
This MR introduces the library for encoding/decoding of NAS Authentication
Reject (8.2.5.1 of 3GPP TS 24.501) and relevant unit test.
The message is sent by the AMF to the UE to indicate that the authentication
procedure has failed. A NAS handler was also introduced.
CI: Add "may_fail" step to execute flaky steps
Add a generic may_fail CI XML step option that indicates the CI step may
fail, but the CI would still be marked as succeeded (instead of skipping
all steps and mark as failed). The cause of this failure depends on the
specific step, e.g., Iperf failing because of low throughput. This
allows to clean up some code and e.g. remove the command_fail option of
Custom_Command, which is then superfluous (and less generic). An
inconvenience is that those may_fail steps will be marked as "failed" in
the HTML. Later cleanup can correct this.
The may_fail is used for executing FHI7.2 testing to push 700 Mbps in DL
(close to the maximum).
Fix some bugs and add some clean up, see commit messages.
Enabling usage of ulsyncvalidityDuration timer in SIB19
ntn-UlSyncValidityDuration in SIB19 from Spec 38.331 v17.12 A validity
duration configured by the network for assistance information which
indicates the maximum time duration (from epochTime) during which the UE
can apply assistance information without having acquired new assistance
information. The unit of ntn-UlSyncValidityDuration is second. Value s5
corresponds to 5 s, value s10 indicate 10 s and so on.
ntn-UlSyncValidityDuration-r17 ENUMERATED{ s5, s10, s15, s20, s25, s30, s35,s40, s45, s50, s55, s60, s120, s180, s240, s900}
Implementation of epochtime is under discussion.
It can be configured in configuration file according to the above
enumeration. For GEO - 240s, MEO - 20s, LEO-5s can be used.
Handle authentication not accepted by the network. The handler assumes the message
is not integrity protected, processes the received NAS message and logs whether a
EAP-failure is enclosed. The UE enters state: 5GMM-DEREGISTERED.
Not done in this commit: the UE shall performs actions as per 5.4.1.3.5 of
3GPP TS 24.501, including (1) Abort any ongoing 5GMM procedure
(2) Stop all active timers: T3510, T3516, T3517, T3519, T3520, T3521
(3) Delete stored SUCI. (4) handle EAP-failure message.
