Kirill Smelkov authoredElse enb treats args="" unset and implicitly uses /dev/sdr0 by default. We do not want implicit default behaviour -> we want to see an error.

We currently have support for a3_offset and a3_time_to_trigger only, while there is also a3_hysteresis plus at least a1_*, a2_* and probably other parameters. Simple A3-only based meas_config tuning might be appropriate for ORS, but for generic enb it is better to expose full control which I do not currently feel good to implement right now. So do not expose it at all on generic to avoid establishing a public API yet. enb.jinja2.cfg already has corresponding comments: {# TODO fully expose lte meas_config_desc in generic SR #} meas_config_desc: { ... {# TODO fully expose nr meas_config_desc in generic SR #} meas_config_desc: { -

- Indicate that it is not for ORS, but for generic case. - Move ue to the end, to where it logically belongs. - Indicate shared instances clearly with clear visually appearing indent. For now it is only about SIM card, but later we will be adding more kinds of shared instances, so it will be needed to clearly see on the UR if an item is a kind of service, or a shared instance of a service.

There is now only 2 kinds of softwares - ORS and generic, and their cfg.json will diverge with ORS staying as it is now for backward compatibility, and generic gaining more features and more kind of shared instances. That means that it no longer makes sense to render those two from a common source. -> Stop rendering them and leave previous rendered result in place for further manual edits.

Previously, e.g. for ORS it was: enb index=0 gnb index=1 core-network index=2 core-network-slave index=3 which resulted in the following appearance order on SlapOS Master UI: gnb core-network core-network-slave enb Note that enb comes last instead of being first as originally intended. That happens because SlapOS Master treats index=0 as being unset and puts all items with unset index in the end. -> Fix this by starting explicitly-set indices from 1. Now, for ORS, the order on UI is enb gnb core-network core-network-slave -

As explained in the previous patch now once we have software.cfg and software.cfg.json, json-schemas started to analyze them instead of skipping software/ors-amarisoft/ completely, and it started to complain about missing response schemas, for example: ERROR: test_ors-amarisoft_software_cfg_json (slapos.test.test_json_schema.TestJSONSchemaValidation) ---------------------------------------------------------------------- Traceback (most recent call last): File "/srv/slapgrid/slappart91/srv/runner/software/45a1e838784afb18daf420009d925c78/eggs/jsonschema-4.17.3-py3.9.egg/jsonschema/validators.py", line 909, in resolve_from_url document = self.store[url] File "/srv/slapgrid/slappart91/srv/runner/software/45a1e838784afb18daf420009d925c78/eggs/jsonschema-4.17.3-py3.9.egg/jsonschema/_utils.py", line 28, in __getitem__ return self.store[self.normalize(uri)] KeyError: 'file:///srv/slapgrid/slappart91/srv/project/slapos/software/ors-amarisoft/instance-ue-schema.json' During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/srv/slapgrid/slappart91/srv/runner/shared/python3/dd8479ce2a2b9dff51f7185535dd0403/lib/python3.9/urllib/request.py", line 1503, in open_local_file stats = os.stat(localfile) FileNotFoundError: [Errno 2] No such file or directory: '/srv/slapgrid/slappart91/srv/project/slapos/software/ors-amarisoft/instance-ue-schema.json' During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/srv/slapgrid/slappart91/srv/runner/software/45a1e838784afb18daf420009d925c78/eggs/jsonschema-4.17.3-py3.9.egg/jsonschema/validators.py", line 912, in resolve_from_url document = self.resolve_remote(url) File "/srv/slapgrid/slappart91/srv/runner/software/45a1e838784afb18daf420009d925c78/eggs/jsonschema-4.17.3-py3.9.egg/jsonschema/validators.py", line 1018, in resolve_remote with urlopen(uri) as url: File "/srv/slapgrid/slappart91/srv/runner/shared/python3/dd8479ce2a2b9dff51f7185535dd0403/lib/python3.9/urllib/request.py", line 214, in urlopen return opener.open(url, data, timeout) File "/srv/slapgrid/slappart91/srv/runner/shared/python3/dd8479ce2a2b9dff51f7185535dd0403/lib/python3.9/urllib/request.py", line 517, in open response = self._open(req, data) File "/srv/slapgrid/slappart91/srv/runner/shared/python3/dd8479ce2a2b9dff51f7185535dd0403/lib/python3.9/urllib/request.py", line 534, in _open result = self._call_chain(self.handle_open, protocol, protocol + File "/srv/slapgrid/slappart91/srv/runner/shared/python3/dd8479ce2a2b9dff51f7185535dd0403/lib/python3.9/urllib/request.py", line 494, in _call_chain result = func(*args) File "/srv/slapgrid/slappart91/srv/runner/shared/python3/dd8479ce2a2b9dff51f7185535dd0403/lib/python3.9/urllib/request.py", line 1481, in file_open return self.open_local_file(req) File "/srv/slapgrid/slappart91/srv/runner/shared/python3/dd8479ce2a2b9dff51f7185535dd0403/lib/python3.9/urllib/request.py", line 1520, in open_local_file raise URLError(exp) urllib.error.URLError: <urlopen error [Errno 2] No such file or directory: '/srv/slapgrid/slappart91/srv/project/slapos/software/ors-amarisoft/instance-ue-schema.json'> During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/srv/slapgrid/slappart91/srv/project/slapos/slapos/test/test_json_schema.py", line 72, in run resolver.resolve(software_type_definition['response']) File "/srv/slapgrid/slappart91/srv/runner/software/45a1e838784afb18daf420009d925c78/eggs/jsonschema-4.17.3-py3.9.egg/jsonschema/validators.py", line 898, in resolve return url, self._remote_cache(url) File "/srv/slapgrid/slappart91/srv/runner/software/45a1e838784afb18daf420009d925c78/eggs/jsonschema-4.17.3-py3.9.egg/jsonschema/validators.py", line 914, in resolve_from_url raise exceptions.RefResolutionError(exc) jsonschema.exceptions.RefResolutionError: <urlopen error [Errno 2] No such file or directory: '/srv/slapgrid/slappart91/srv/project/slapos/software/ors-amarisoft/instance-ue-schema.json'> -> Fix this and all other similar errors by adding stub response schemas for all objects that is possible to instantiate. -

Previously json-schemas tests were passing on software/ors-amarisoft but the status was misleading: since json-schemas check only software.cfg.json, and until recently - before the patch to switch RU type to be a runtime parameter, there was _no_ such file in here, nothing about software-*.cfg.json was checked at all. But after the switch we started to have software.cfg and software.cfg.json files which json schemas checks and errors start to appear. Here we fix the following error popping up due to extra blank lines around "ue" entry in software.cfg.json: FAIL: test_ors-amarisoft_software_cfg_json_format (slapos.test.test_json_schema.TestJSONSchemaValidation) ---------------------------------------------------------------------- Traceback (most recent call last): File "/srv/slapgrid/slappart91/srv/project/slapos/slapos/test/test_json_schema.py", line 85, in run self.assertEqual( AssertionError: Lists differ: ['{',[145 chars]{', ' "ue": {', ' "title": "UE",', ' [1344 chars] '}'] != ['{',[145 chars]{', '', ' "ue": {', ' "title": "UE",',[1352 chars] '}'] First differing element 5: ' "ue": {' '' Second list contains 2 additional elements.

Previously RU type was static parameter of particular software - it was possible to instantiate cells only with selected RU type for particular template. In MultiRU it will be possible to generally instantiate all kind of cells - LTE/NR and TDD/FDD all at the same time and each served by a different kind of Radio Unit. -> Switch RU to be runtime parameter as a preparatory step for that. There is now only two software releases: - ORS (software-ors.cfg), and - generic (software.cfg). ORS behaviour stays the same as before here by patch. For generic each cell in cell_list now needs to explicitly specify which kind of RU it wants to use and with which parameters. There are less defaults: for example which CPRI board and SFP port to use now needs to be explicitly specified. Only ORS tests are left for now. The old test{LOPCOMM,M2RU,ANY} did not exercised any driver-specific functionality and until recently were not run at all due to '-' in their file name. We remove them for now and we will add tests for generic in a soon follow-up patch after switching LTE/NR cell type to also be a runtime parameter. Backward compatibility: * nothing changes for ORS * for generic all RU-related parameters are now moved from cell_list to cell_list.ru, there are several renames and besides ru_type ru_link_type also needs to be specified. Please see new RU-related JSON schemas added into ru/ for details. Cell_list itself now also does not provide a default with one cell - if no cells are configured no cells are instantiated. -------- Appendix.

Previously rf_mode was static parameter of particular software - it was possible to instantiate cells only of the mode selected for particular template. In MultiRU it will be possible to generally instantiate all kind of cells - LTE/NR and TDD/FDD all at the same time. -> Switch rf_mode to be runtime parameter as a preparatory step for that. Software for ORS becomes just software-ors.cfg with software-tdd-ors.cfg providing backward compatibility proxy as we have many ORS'es currently deployed with that software-release URL. For other softwares backward compatibility is not preserved including for software-fdd-ors.cfg because we practically have very few deployments with those. To show tdd_ul_dl_config only for TDD we use conditional feature of new JSON-editor. Backward compatibility: nothing changes for ORS, for everything else rf_mode now needs to be explicitly set in cell parameters if it is not TDD. Rendered enb.cfg and gnb.cfg stay the same.

Similarly with cell_list, organize a loop in under nr_cell_list and emit configuration for each NR cell we have. Tests will be added later as full tests for generic MultiRU. Only trivial space and comments changes in rendered gnb.cfg Backward compatibility: no change for ORS and everything else.

So far CA was setup only for lte case and it is possible to simplify generation of all pair of cells to be done without extra loop and state.

As with Radio Units organize a registry of cells and start to handle that registry generally everywhere. Make parameters that configure cells, for example tdd_ul_dl_config, dl_earfcn, bandwidth, pci, etc to be per-cell. Cell registry is still populated from cell_list and slapparameter_dict.

Most were already so, but sdr_number and cpri_mult were not. We need to be able to use different SDR boards and with different CPRI speed, so make those parameters to be per-RU as well. Backward compatibility: no change for ORS; For CPRI-based cases sdr_number and cpri_mult become per-RU.

Like e.g. txa0cc00_center_frequency, rxa0cc00_center_frequency_earfcn, etc - because different units needs to use different parameters. cron_schedule is renamed to -> reset_schedule to better reflect its meaning. user-authorized-key remains to be global as this is per-eNB nor per-RU property, but is likely unneded in the future. Corresponding FIXME is added to highlight this. Backward compatibility: no change for ORS; lopcomm parameters become per-cell and need adaptation.

Add code to organize a registry of Radio Units and handle that registry generally everywhere. RU registry is still populated from cell_list and in practice there still can be radio units only of the same type, but besides slaplte.load_ru_and_cell which is aware of that, the rest of the code tries to do everything as if RUs of different type could be present simultaneously. Now it is not only lopcomm who can do multiCELL, but also sunwave and SDR as well. gNB also starts to gain support for cell_list, because cell_list loading is uniformly applied to both eNB and gNB. However, since enb.cfg is not yet prepared to handle multiple NR cells yet, there is an assert that in case of NR there is only one RU/cell present there. We will remove this limitation in a follow-up patch. Later we will also change the loading to load RU descriptions from shared instances and they won't be constrained to be Radio Units of the same type. But we need to prepare a lot to be able to do that. One more step forward towards MultiRU. Tests will be added later as full tests for generic MultiRU.

Previously type of emulated UE was static parameter of particular software release - it was possible to simulate UE and attach to cells only of the RAT of particular template. In MultiRU it will be possible to generally emulate all kind of UEs - both LTE and NR all at the same time, and attach them to LTE and NR cells simultaneously. -> Switch type of UE to be runtime parameter as a preparatory step for that. URLs of software releases changes (we remove lte and nr in names), but here we do not care about backward compatibility because currently there are just a few UEsim deployments and migration should be easy.

ORS does not support UEsim as indicated by `if bbu != ors` in software.cfg.json.jinja2. Amends f3f1cb46 (software/ors-amarisoft: Start to introduce ORS mode) because that patch started to really reject instantiating ue-* on ORS.

Soon we are going to make rf_mode a runtime parameter and so there won't be TDD and FDD in software names anymore. Prepare to that and make --delete to remove the exact set of files that render-template actually generates instead of becoming a noop after "runtime rf_mode" restructuring.

We are currently querying it in instance.cfg and later, once again, in e.g. instance-enb.jinja2.cfg . However ORS mode will need to adjust slapparameter_dict with ORS defaults and pass it further to generic enb. So it won't work if we use slapparameter_dict obtained the second time because the second query will return unadjusted original slapparameter_dict. In this patch we are only doing preparatory step - redo the code not query the master from instance-{enb,ue}.jinja2.cfg and work with slapparameter_dict and slap_configuration already queried by instance.cfg For UE the change is trivial. For eNB instance-enb.jinja2.cfg used to set the defaults for com, mme, amf and gtp in the same section used for the second query. We rework those defaults to be applied to slapparameter_dict via jinja2 - via the same way we are going to later use in ORS mode. Handling defaults for everything besides gtp_addr is straightforward. For gtp_addr it has the semantic difference when explicitly given, and given only implicitly. In the latter case the intent of original code is to autodetect whether to use an address on loopback, or externally-visible address. Original code used the check for emptiness of mme_list/amf_list as the condition for "use loopback". Since now those lists, after applying their defaults, are never empty we rework the code to see if core address is on the loopback or not, and use auto-GTP-on-loopback only if core is also on loopback. This should, hopefully, be more convenient as it also works ok out of the box if core is on loopback, but its address was explicitly specified. Previously for such cases gtp_addr was also needed to be specified, and now it should work without that. No change to rendered enb.cfg and gnb.cfg besides whitespace. Adjust ipv6-random usage in core-network for consistency with enb as well. -

For example it is the port that is setup in ru/dnsmasq.jinja2.cfg that is used, not :port and there it is 5354, i.e. different. :ip is also not used anywhere. -> Remove them to avoid confusion.

Not only inside rendered enb.jinja2.cfg and ue.jinja2.cfg because we will need that information in slaplte and slaplte is imported by instance-enb and instance-ue.

instance-enb and instance-ue currently setup that slap_configuration with LTE/NR defaults to be accessible from enb.jinja2.cfg and ue.jinja2.cfg. But we will soon need to have access to those defaults from slaplte.jinja2 as well, and it will break if left as is because when slaplte is imported from e.g. enb.jinja2 - it will work, but when slaplte is imported from instance-enb it will break because parent of instance-enb (instance.cfg) does not setup defaults in slap_configuration at that level. The fix is to either duplicate slap_configuration at instance.cfg level, or to switch access to the defaults to go via original default_* parameters. We go the second way for simplicity.

software/ors-amarisoft: enb.jinja2.cfg: Switch internal ru.ru_type to be 'sunwave' for Sunwave M2RU Radio Unit ru/libinstance and everything inside there already refer to that unit as 'sunwave'. Do the same for uniformity in enb.cfg and because we already refer to Lopcomm ORAN Radio Unit as just 'lopcomm'. In the future, if we will need to distinguish different models of one manufacturer, we could extend ru type to be e.g. manufacturer/model or do something similar. Template rendering is still done with ru='m2ru' coming from outside but internally it is now ru.ru_type='sunwave' instead of ru.ru_type='m2ru'.

Even though I introduced cell object in 79370ebf (software/ors-amarisoft: enb.jinja2.cfg: Stop using C Preprocessor and switch to Jinja2 completely) it is currently only cell.bandwidth that is living there, while all other cell parameters are still fetched from slapparameter_dict directly. We will soon introduce cell variable - that will iterate over cell_dict, and also keeping global cell won't work due to name shadowing. On the other hand we are not yet ready to start migrating all cell parameters to be accessible via cell object. -> So inline code for lte bandwidth parameter until the time comes to rework all cell parameters to be accessible via cell object. Rendered enb.cfg and gnb.cfg stay the same.

To handle multiple radio units we will need to rework this code significantly. Move this to a dedicated routine as a preparatory step. The code moves out of enb.cfg because later it will be also used in UEsim to configure simulator radio units as well.

To run tapsplit we use plone.recipe.command with both command and update-command set to `tapsplit ...`. But tapsplit, when run, fully recreates and reinitializes subtap interfaces, which leads to interfering with running enb because subtap interfaces, that enb started to use, are removed. This is not desirable behaviour. What we need: 1) create subtap interfaces only once and keep them stable 2) until configuration changes which should lead to * subtaps recreated, and * enb restarted Carefully reading plone.recipe.command documentation shows: command Command to run when the buildout part is installed. update-command Command to run when the buildout part is updated. This happens when buildout is run BUT THE CONFIGURATION FOR THIS BUILDOUT PART HAS NOT CHANGED. (emphasis mine) So the fix looks to be to make update-command noop - this fulfills requirement "1". For "2" - I've verified that when configuration changes, e.g. number of RU changes, buildout reinstalls [vtap] section from scratch, and it also should restart enb, because generated enb.cfg changes. So the fix is fully correct because it satifies all needed requirements.

In f3f1cb46 I've made a mistake in "inject ORS defaults" code - there it should be RF.dl_earfcn and RF.dl_nr_arfcn instead of RF.earfcn and RF.nr_arfcn.

Don't repeat slapparameter_dict['ncell_list'][k] - we can introduce a name for current neighbour cell, and use that name in the loop. And align entries to that they read more clearly.

We currently have LTE-specific handover configuration in under cell_list and NR-specific handover configuration in under nr_cell_list. Those configuration are different. However in upcoming MultiRU we will need to handle LTE->NR handover, NR->LTE handover, and also Intra-ENB handover in addition to Inter-ENB handover we currently do. -> Move handover code into common function as a preparatory step for that. In the future the handover code for LTE and NR cells will be the same, so it makes sense to move that code to common place to avoid duplication. For rendered enb.cfg this unification introduces only space and trivial changes as shown in the appendix. /cc @jhuge, @lu.xu, @tomo, @xavier_thompson, @Daetalus /proposed-for-review-on nexedi/slapos!1528 /reviewed-by TrustMe Appendix.

1. Currently we have separate log_options for LTE and NR cases with listing different subsystems in each. But in MultiRU one enb will be driving both LTE and NR cells at the same time, so we will need to define both LTE- and NR-related levels. -> Merge all log settings into one log_options as a preparatory step For current state it does not hurt for an LTE if we set e.g. ngap.level, and it does not hurt for NR if we set e.g. s1ap.level - since those layers will be unused. This way merging log settings for both LTE and NR subsystems is ok. -------- 2. Factorize log_phy_debug handling: instead of duplicating whole log_options line and changing only phy.level settings there, construct the log_options line programmatically and handle phy.level on its own. -------- 3. Use log/enb.log log_filename for both LTE and NR cases. In the upcoming MultiRU there might be several cells activated at the same time and in general it will be not possible to say are we doing "enb" or "gnb" now - for example if there will be two cells - one LTE and one NR. -> Use enb.log for log filename uniformly similarly to how the software is named (lteenb) even though it can work as both enb and gnb. For the reference we do the same with enb.xlog in nexedi/slapos!1522 . /cc @jhuge, @lu.xu, @tomo, @xavier_thompson, @Daetalus /proposed-for-review-on nexedi/slapos!1527 /reviewed-by TrustMe Appendix.
