Kirill Smelkov authoredFor example if we need to do 4T4R but have SDR boards with only 2T2R ports, we need to combine two such boards into single RF port. Allow to do that via changing SDR schema from taking sdr_dev into accepting sdr_dev_list and adjusting the code everywhere correspondingly. For ORS full backward compatibility is preserved via adjusting "ORS mode" proxy correspondingly. One example in slapos-render-config.py is changed from 2T2R to be 4T2R on such RF port combined from two SDR boards. For that example the diff for rendered enb.cfg is as follows: --- a/config/old/enb/iRU1_SDR_tLTE2_tNR/enb.cfg +++ b/config/out/enb/iRU1_SDR_tLTE2_tNR/enb.cfg @@ -8,7 +8,7 @@ rf_driver: { // __CELL__a__ru 4T2R (sdr) name: "sdr", - args: "dev0=/dev/sdr0", + args: "dev0=/dev/sdr0,dev1=/dev/sdr1", }, tx_gain: [51, 51, 51, 51], rx_gain: [52, 52], All other cases, including ORS, remain without any change. -

We currently have at least the following problem: 1. a malfored shared instance reference leads to instantiation failure and potential buildout code injection. For example if reference of shared instance contains space then buildout fails with something like zc.buildout.configparser.ParsingError: File contains parsing errors: .../instance-enb.cfg [line 45]: '[promise-testing partition 0.RU-sdr-busy]\n' since, when requesting, it is possible to use arbitrary characters for references, including newline, it also opens the door for code injection attacks. 2. we currently use `json` directive of slapos.recipe.template e.g. as extra-context = json iru_dict {{ rulib.iru_dict | tojson }} this also potentially leads to instantiation failure if JSON(rulib.iru_dict) contains buildout control characters. Solve this problems. For 1 we develop "buildout encoding" that encodes arbitrary string into form that is safe to be used as a name of buildout section. This encoding never fails and does not loose information, which means it is safe to be applied unconditionanly and there is no chance for two string inputs to result in the same encoded form. The encoding also has practical property that it leaves most of the strings, that we use in our buildot profiles, intact. Which means that the result of the encoding is readable and the encoding can be applied almost unconditionally to all strings without hurting instantiation. Then this encoding is applied wherever reference of a shared instance is used to form e.g. name of buildout section or inside other codes. We apply this encoding universally - in config files too to avoid breakage there - e.g. in enb.cfg to protect from e.g. \n being inserted in the middle of comment resulting in YAML breakage. See documentation of added xbuildout.py for details. For 2 we switch from `json` to using `dumps` on an object and referring that dumps result via `key` directive. See the following links for preliminary discussions with Jérome and Vincent on this topic: d5d4f7c8 nexedi/slapos@bf6b2ef3 -

As promised add tests for generic enb that exercise enb instantiation with multiple Radio Units and cells in all kind of combinations: FDD|TDD x LTE|NR x SDR|Lopcomm|Sunwave and not only one particular case, but verifying instantiation with many combinations at the same time - verifying how cells of different kinds are handled and how radio units of different kinds are handled too. Using multiple cells on top of several radio units of the same type is verified too. For Lopcomm we also exercise generated cu_config.xml a bit. See added tests for details. Enb/generic tests are bootstrapped now. From now one every fix to enb/generic and every semantic change will go on only if it is accompanied test change or enhancement.

As promised in indicated TODO. It is useful for debugging and for being able to take all the rendered files, copy them to a callbox, and to be able to run lteenb directly on them. Besides enb.cfg we need to also have those drb and asn23, because enb.cfg references them.

Extend slapos-render-config to simulate not only what ORS does, but also simulate multiple radio units and/or multiple cells with RU being SDR or CPRI-based Lopcomm. It is useful as an example on how to configure things in new "shared instances" MultiRU, and to verify handling of all those combinations.

software/ors-amarisoft: enb/generic: Switch configuration of RU, cell, peer and peercell to shared instances Previously we had cell_list, ncell_list and peers parameters and we now remove them and rework the software release to accept configuration for said objects via shared instances. In other words now it is possible to add Radio Units, cells, peers and peer cells on on top of main eNB service. Schema for parameters of those shared instances is based on what we just recently generalized and established in ru/ cell/ peer/ and peer/cell/ input schemas. We only add cell_kind=enb|enb_peer addition field to be able to distinguish a cell from peercell object, and we add a way for cell to reference RU one way or another. RU-CELL relation is no longer 1-1: one RU can be generally serving multiple cells. For example transmission bandwidth of SDR100 board is ~ 100MHz while bandwidth of one LTE cell is max 20MHz. This way it is possible to put several cells whose frequencies are nearby each other to be run on the same SDR board(*). And in general one Radio Unit can be serving transmission/reception in multiple frequency ranges, thus providing ability for multiple cells to be served by RU. This way RU is split off from CELL object and each CELL needs to say which RU object it wants to use. There are 3 ways to configure CELL->RU links: 1. CELL references a RU object. This is the most general. 2. CELL embeds definition of RU object. This variant is provided for simplicity of management for users that do not want to split CELL/RU relations. 3. CELL2 references another cell object and says to use the same RU as CELL1. Again, this variant is provided for simplicity of management when users want to add a cell on top of same RU when they already started with "2". Full backward compatibility is provided for ORS. For this instance-ors-enb.jinja2.cfg is adjusted to inject synthetic RU/CELL/PEER/PEERCELL shared instances instead of translating to slapparameter_dict. As the result for ORS users it works without visible change as parameters with original ORS schema are handled as expected. Rendered files for ORS also stay practically the same as before this patch. The main change is in slaplte.jinja2 - in the loading routines. The other changes are mostly straightforward adaptation because details of how ru_dict, cell_dict, peer_dict and peercell_dict are loaded were already localized to slaplte and the rest of the code independent from that. Now, once we switched to shared instances, we will be finally able to add tests for updated enb. Please see a soon follow-up patch for that. And for existing test_ors.py we also temporary workaround breakage of tests, because currently generic code does not handle well special characters in partition references. For example it currently breaks on spaces with buildout complaining that sections with spaces in their name are invalid. We will fix that in another soon-followup patch as well, but apply a workaround for now. (*) see https://tech-academy.amarisoft.com/SDR_MultiCell_OneSdr.html for details. -------- Appendix.

The procedures to generate those are currently very similar, and that's why we employ a shared `do` function to render them. But enb and ue rendering will become different from each other in the next step. -> Prepare to that by pushing necessary bits of do into do_enb and do_ue insides. No change in rendered files.

In other words merge enb and gnb into sole enb that can handle both LTE and NR cells at the same time and simultaneously. Previously which type of Radio Access Technology to use - LTE or NR - was static parameter of particular software - it was possible to instantiate cells only with selected RAT for particular template. In MultiRU it is 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 cell type to be runtime parameter as the final step to be able to do that. For generic cell definitions are now required to come with cell_type=lte|nr parameter. In schemas cell_list now includes oneOf for lte|nr cell instead of particular cell type. Similar adaption is done for ncell_list and x2_peers/xn_peers are merged into just peers with similar oneOf. Global gnb-specific parameters of went-away gnb are also added as global ones to enb: - gnb_id - gnb_id_bits - amf_list - plmn_list (as plmn_list_5g not to conflict with plmn_list) - nssai They must be present if there are NR cells. Full backward compatibility is preserved for ORS: now it injects cells to generic with particular cell_type annotations and translates ORS-specific x2_peers/xn_peers and gnb/plmn_list to proper generic parameters. In ORS-gnb schema gnb_stats_fetch_period and gnb_drb_stats_enabled had to be renamed to enb_stats_fetch_period and enb_drb_stats_enabled, but once again, full backward compatibility is preserved because ORS mode already had the following in its proxy: {#- backward compatibility: if ORS is running in gnb mode, and gnb_* parameters are present, replace their generic enb_* counterparts with gnb_* ones #} ... The diff for rendered enb.cfg and gnb.cfg, that simulate ORS, before and after hereby patch is also empty. -

As with Radio Units and cells organize a registry of peer cells and start to handle that registry generally everywhere. The registry is still populated with only LTE cells on enb and only NR cells on gnb, but the only place that is aware of that is registry loading routine. In the old code defaults were noticed for tac to be 1 if not provided, and so those defaults are pushed to live in ORS now. ORS schemas are also updated because that defaults were not declared there. Generic switches to use peer/cell/lte directly which means that now it accepts e_cell_id instead of cell_id as the name for full E-UTRAN cell identity. Full backward compatibility is provided for ORS which implements translation of its original schema to the new generic one. Tests will be added later as full tests for generic MultiRU. Rendered enb.cfg and gnb.cfg change a bit, but the changes are mostly due to reordering of fields. The only change with semantic value is - ssb_nr_arfcn: , + ssb_nr_arfcn: 520090, in gnb.cfg . The old configuration was invalid anyway because if it is only ssb_nr_arfcn: , then enb does not start with the following error: # ../lteenb gnb.cfg gnb.cfg:119: unexpected token: ',' Like with many other handover-related fields https://tech-academy.amarisoft.com/lteenb.doc#prop.ncell_list.ssb_nr_arfcn documents that ssb_nr_arfcn "Must be present" for Inter-gNB HO case. The old code was erroneously doing `ncell.get(name, '')` with yielding empty string in case a parameter is missing, which is corrected here. -------- Appendix.

Move schema of peer cells into under peer/cell/lte and peer/cell/nr with keeping in mind that peer/cell will become a separate entity in MultiRU. NR deduplication is straightforward, but for LTE original ncell_list used `cell_id` name for full E-UTRAN cell identity. peer/cell/lte uses e_cell_id name for that and content of that peer/cell/lte cannot be applied directly to ORS's ncell_list and ncell_list in current enb/generic. To keep things working we pickup peer/cell/lte field by field with mapping e_cell_id into cell_id. For the reference for NR both original ncell_list and new peer/cell/nr use nr_cell_id for full 5G cell identity. Backward compatibility: nothing practically changes for ORS and generic.

software/ors-amarisoft: enb+ue: Switch to JSON schemas as the primary source of defaults; stop rendering them JSON schemas for eNB/gNB and UE specify defaults for many parameters and the software release use those defaults when parameters are not explicitly specified on the instantiation. Some primary defaults - for bandwidth and n_antenna DL/UL - were setup in render-templates and propagated through all places to avoid duplicating them. Defaults for many other parameters were duplicated in both JSON schemas and in the code that handles those parameters. To avoid this duplication we either need to extend render-templates and put defaults for all the other many parameters there, or just switch to JSON schemas to be primary source of those defaults, and use the schemas on instantiation by automatically loading them and extracting defaults for all parameters from there. I decided to go the second way because it avoids additional layer of rendering and the need to keep on remembering not to put raw defaults in the JSON schemas. Evidently this is the same approach that Rapid CDN is going to take (see nexedi/slapos!1380 for details). In this patch we stop rendering JSON schemas and keep their last rendered result. In the later patches we will handle formed duplication there and go on to further merge enb and gnb. UE is handled brutally for now, because it will be much reworked after. Actually loading JSON schemas is left as TODO as I do not have resources to implement that now. Still this step is needed as precondition for further patches. I hope bit of duplication for enb/gnb parameters is ok, given that they are now centrally maintained and corresponding TODO warning is in place.

We currently have 2 kinds of software: - ORS, whose intended usage is small private networks, and - generic, whose intended usage is small-to-medium networks. and currently they both share defaults for their parameters inherited from ORS. But what is appropriate for small private networks, might be not so appropriate for medium networks. For example ORS has default enb_id/gnb_id, but in a network with 100 nodes, it is better to force every node to be explicitly assigned an id and error otherwise. Similarly for cells ORS has defaults for cell_id, but in network with many nodes, cell_id needs to be explicitly assigned. With having a default there is also a chance to misspell the parameter name, and do not notice it because the software will instantiate without an error but work incorrectly. So in this patch we tighten the defaults for generic: - enb_id, mme_list become non-optional for LTE - gnb_id, afm_list become non-optional for NR - plmn_list becomes non-optional for both LTE and NR. The format is different in between RATs and so later we will use plmn_list and plmn_list_5g when merging enb and gnb. - the following parameters of LTE cells now needs to be explicitly configured: rf_mode, dl_earfcn, bandwidth, cell_id, pci, tac. - the following parameters of NR cells now needs to be explicitly configured: rf_mode, dl_nr_arfcn, nr_band, bandwidth, cell_id, pci. We rework ORS mode to translate its own set of parameters and defaults into generic enb/gnb parameters. We similarly pull some global generic defaults into instance-enb.cfg.jinja2 with the idea that they could be maintained in one central place. In the future it would be good to automatically load them from JSON schemas to avoid duplication. This patch should be backward compatible for ORS, but it introduces the change in cell_id and pci in rendered enb.cfg which become 1 instead of 0: --- a/config/old/enb.cfg +++ b/config/out/enb.cfg @@ -33,9 +33,9 @@ n_antenna_dl: 2, n_antenna_ul: 2, - cell_id: 0x00, + cell_id: 0x01, tac: 0x0001, - n_id_cell: 0, + n_id_cell: 1, root_sequence_index: 204, dl_earfcn: 36100, inactivity_timer: 10000, The defaults for those parameters according to instance-enb-input-schema.json are 0x01 and 1.

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.

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. Tests will be added later as full tests for generic MultiRU. Backward compatibility: no change for ORS, which has only one cell, and rendered enb.cfg and gnb.cfg stay the same.

For uniformity with LTE where it already is. We do not expose it in ORS schema because it will be exposed only in generic LTE and NR schemas, but for ORS schemas I prefer to keep them intact myself.

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. Tests will be added later as full tests for generic MultiRU. Rendered enb.cfg and gnb.cfg stay practically the same.

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. Backward compatibility: no change for ORS and practically no breaking change for everything else. -------- Appendix.
