Fix the problem that duplicate type names exist in OPEN TYPE.
The following excerpt of ASN.1 of X2AP is one example.
HandoverRequestAcknowledge-IEs X2AP-PROTOCOL-IES ::= {
{ ID id-Old-eNB-UE-X2AP-ID CRITICALITY ignore TYPE UE-X2AP-ID PRESENCE mandatory}|
{ ID id-New-eNB-UE-X2AP-ID CRITICALITY ignore TYPE UE-X2AP-ID PRESENCE mandatory}|
...
}
1. Fix the problem of compiling NR_RangeToBestCell.c of NR-RRC 15.3.0
2. Fix the problem that default OCTET/BIT STRING value not used in APER
3. Add support of extension group inside CHOICE type used in LTE-RRC 15.3.0
4. Fix the problem that NGAP 15.0.0 ASN.1 can not generate C files
- install package 'vim-common' to have 'xxd' needed by the compilation
process of the T tracer
- change the way xxd is called so that no file is created in case
of error
1. It's no need to modify LTE-RRC's ASN.1 file for enabling option group
feature in generate_asn1.
2. It's no need to patch the C header files generated from
LTE-RRC/S1AP/X2AP's ASN.1 in fix_asn1.
3. It's no need to pre-process S1AP/X2AP's ASN.1 for enabling information
object class feature by asn1tostruct.py.
This commit requires an un-official version of asn1c which are
collaboration of asn1c community members and `build_helper` is modified
in this commit accordingly :
https://github.com/brchiu/asn1c/tree/velichkov_s1ap_plus_option_group
This asn1c can also convert ASN.1 of 5G NR RRC (38.331, v15.1.0) and
generate C files with -findirect-choice command line option without
tweaking ASN.1 file.
Examples for how to use this asn1c for S1AP are in S1AP files, e.g.
s1ap_eNB_nas_procedures.c and s1ap_eNB_handler.c.
There is an modified openair-cn (based on tag 0.5.0) with this new asn1c at :
https://github.com/brchiu/openair-cn/tree/new-asn1c
Basic S1AP interaction and data transfer operation between OAI eNB and
this modified openair-cn has been tested.
Note: Community version of asn1c is keeping evolved to provide better usage.
-- Stability issues when installing packages for USRP variants on new VM
It sometimes timed-out
Added loop up to 5 tries to add apt-repository
-- Temporary merge during MergeRequest processing now returns an
error when there are any conflicts
Will stop the whole build
-- Physical simulator now has a XLST for the XML result

It has been chosen to not include the full history of commits
from David. He included a binary version of wireshark, probably
a modified one that understands NFAPI. Wireshark is released under
the GPL license, we cannot include it in the repository. We could
have done a next commit to remove this binary. But then it would
still be present in the history of commits, which may not be allowed.
And it would take space on disk. We could edit the history to remove
wireshark entirely. But this operation is too complicated.
There was also a pcap capture file, which has nothing to do in
the history of commits and would take space on disk. There again,
it's too difficult to edit the history to remove it.
There was a file .gitignore that was also removed.
The original history can be found on David's repository:
https://gitlab.eurecom.fr/daveprice/openairinterface5g/
The branch is: nfapi-ru-rau-split.
A copy of that branch has been included in the internal OAI
repository, for those who have access to it.
The branch is the same. The last commit ID is
9106438239e0bc626ff1fa1d97d911caadd0fbb9.
You can compare the current commit with the commit 9106...
to see what differs.
The current commit has to be considered non-working.
The commit following the current commit will fix problems with
the work in the current commit.
If you use git bisect, don't spend time analyzing the current
commit.
Basically, build_helper has been adapted so that:
./buil_oai -I -w USRP
works for Ubuntu 17.04 and 17.10.
Concerning those systems:
- compilation with "--eNB --UE -w USRP" works
- the enb softmodem runs on 17.04 (not tested on 17.10)
- nothing else has been tested.
Users should report any problem.
protobuf-c does not compile anymore.
Let's handle this a bit better.
We now install protobuf and protobuf-c only for the
flexran agent. That is, if you want to use the flexran
agent, you need to install protobuf/protobuf-c and
you do it this way:
./build_oai -I -a
(you add -a)
Other targets don't need protobuf nor protobuf-c, so
it's not installed by the -I command of build_oai,
unless you pass -a with -I.
Also, we now use protobuf 3.3.0, not 2.6.1. The code
has been adapted, a quick test seems to indicate that
the system works, but it has not been intensively tested.
Problems reported by Jorge Muñoz Castañer <jorgem@gti.uvigo.es>.
- use Rel14 binaries (those are produced by default)
- let -x option work to have graphical output
- fix VCD missing 'echo'
The files NativeInteger.c.diff and constr_SET_OF.c.diff
from asn1c were generating compilation warnings. We had
local patches applied on generated files by asn1c.
A new version of asn1c has been pushed to
https://gitlab.eurecom.fr/oai/asn1c
(commit 224dc1f991b7e7ad705ce92e171b942f87b7b7e7)
making obsolete the fixes we do here.
So we now remove those fixes.
*************************
* IMPORTANT BEGIN *
*************************
Everyone should update their asn1c installation.
The simplest is to do:
source oaienv
cd cmake_targets
./build_oai -I

- import RRC ASN.1 defintions from the specifications
(file openair2/RRC/LITE/MESSAGES/asn1c/ASN1_files/RRC-e10.asn)
contrary to rel8/10, all modules have been imported, maybe it's too much
to refine in case of problems
- deal with rel14 in fix_asn1
- all code that was for Rel10 is now for Rel10/Rel14
- some incompatible changes (mostly in naming) were resolved in favor
of rel14, see in openair2/RRC/LITE/defs.h
- unsure about the rlc layer, some arrays have changed (values appended),
I only changed the definition and in tests in the code, I changed
the index limit, maybe it's not enough
Rel14 is the default compilation mode.
- build script has ability to indicate location for downloading uhd images
- one simple wrapper to set environment variables and initiate another program (supposed to be lte-softmodem)
This commit reverts behaviour of data generation as before
commit 7207c65b05fd812a18371827f2bfb1431fc58696:
fix .ue* filenames in scripts and documentation
TODO add option to conf2uedata and adapt script
This patch adds the conf2uedata tool for generating .ue.nvram* .ue.emm.nvram*
and .usim.nvram* files from a textual configuration file.
The configuration file define most usefull values like plmns, mnc, mcc, msin, K,
OPc for several users.
The files generated will always ends with a number corresponding to the user
entry in the configuration file.
This breaks oai5g because other script have not be updated for using
conf2uedata.
This breaks also the at_nas_ue command.
Examples of configuration files are in openair3/NAS/TOOLS/
init_nas_s1 may not work properly, but many people complain
about this file, so let's put it in the repository.
We'll fix it at some point if it's not properly usable.
