      erp5: restore ZODB using the --with-verify option of "repozo --recover" · a21d8d03
      Nicolas Wavrant authored
      "repozo --verify" is not working as this code expects it to: it simply
      prints errors in stdout, and doesn't return an error code in case of
      error. Thus, running it had absolutely no effect, except wasting IO
      and CPU time.
      
      This commit introduces the use of "repozo --recover --with-verify",
      which runs the verify and the recover in a same step, and has the
      advantage to raise (it doesn't exit with 0) in case of error. Also, as
      it does the verification and the recovery at the same time, it uses
      half the IO for the read. On a production server using SSDs, with a
      ZODB of 1Tb, runner-import-restore now takes 14h instead of 26h, iow a
      performance increase of 46%.

      software/ors-amarisoft: MultiRU · ed138c6e
      Kirill Smelkov authored
      Hello up there. This merge-request brings in major update to ors-amarisoft
      software release: first eNB is significantly restructured to prepare base for
      further changes, and then we add support for working with multiple radio units
      and multiple cells with all LTE/NR and FDD/TDD simultaneously. All kinds of
      Carrier Aggregation - LTE+LTE, NR+NR and LTE+NR are now supported. All kinds of
      Handover - Intra-ENB, Inter-ENB with LTE→NR and NR→LTE are now supported as
      well. UE simulator is also updated to support multiple radio units, cells and
      UEs. In the new system configuration of RU, CELL, PEERCELL, PEER and UE objects
      are done via shared instances attached to the main eNB or UEsim instance.
      
      Most of the parameters become runtime settings instead of being static choice
      of particular software template. There is no longer multiple rendered
      softwares - all that remain is
      
      1. `software.cfg` for generic software, and
      2. `software-ors.cfg` for ORS.
      
      Switching to configuring things at runtime became possible because SlapOS Master
      recently switched to new JSON-editor with support for `oneOf`, arrays and
      conditionals - bits that make it possible to configure settings in the WEB UI
      with multiple choices for e.g. RF mode, cell or radio unit type.
      
      For ORS full backward compatibility is preserved via special proxy which
      translates ORS input schema to configuration objects of the new generic eNB.
      Since most our current ORS deployments are TDD, `software-tdd-ors.cfg` link to
      `software-ors.cfg` is also provided to preserve backward compatibility at
      software-release URL level for those instances.
      
      eNB and gNB are merged along the way. Unittests are improved. JSON schemas
      become primary source for defaults(*). Unnecessary parameters are removed and
      are now computed automatically. For example it is no longer needed to
      explicitly specify SSB NR-ARFCN for peer NR cell, or `txa0cc00_center_frequency`
      for Lopcomm RU. `tx_gain` and `rx_gain` become generic parameters that
      semantically apply uniformly to all Radio Units.
      
      A protection against buildout code injection via specially-crafted references
      of shared instances is installed. The problem was noticed because instantiation
      was failing with spaces in the references - a condition that is present by
      default on the testnodes. Solving the problem generally via custom "buildout
      encoding" was not hard and probably the solution might be useful not only for
      ors-amarisoft software release. Please see the patch `"Protect from buildout
      code injection"` for details.
      
      There are more minor enhancements and bug fixes in there.
      
      Please see individual patches for details.

      software/ors-amarisoft: Do not recreate slaptapX-* on every idempotent `slapos node instance` run · 7989e6ce
      Kirill Smelkov authored
      To run tapsplit we use plone.recipe.command with both command and
      update-command set to `tapsplit ...`. But tapsplit, when run, currently 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
      3) if subtap interfaces disappear for any reason, recreate it
      
      -> Rework tapsplit to keep its promise, that it "brings tap interface into state
         with several children interfaces each covering part of original interface
         address space", without recreating those children on every run and instead
         doing any action only if their state is not what is desired.
      
      In other words those interfaces now are only created when they do not exist
      before. Addresses and routes are added only if they are not there before
      tapsplit is run, etc.
      
      After the patch the first run of tapsplit to split by 2 looks like
      
          # ./pythonwitheggs ru/tapsplit slaptap16 2
          slaptap16: split 2401:5180:0:66:a200::/71 by 2
          preserve         2401:5180:0:66:a200::/73
          -> slaptap16-1   2401:5180:0:66:a280::/73
           # ip tuntap add dev slaptap16-1 mode tap user slapuser16
           # ip link set slaptap16-1 up
           # ip addr add 2401:5180:0:66:a280::/73 dev slaptap16-1 noprefixroute
           # ip route add 2401:5180:0:66:a280::1 dev slaptap16-1
           # ip route add 2401:5180:0:66:a280::/73 dev slaptap16-1 via 2401:5180:0:66:a280::1
          -> slaptap16-2   2401:5180:0:66:a300::/73
           # ip tuntap add dev slaptap16-2 mode tap user slapuser16
           # ip link set slaptap16-2 up
           # ip addr add 2401:5180:0:66:a300::/73 dev slaptap16-2 noprefixroute
           # ip route add 2401:5180:0:66:a300::1 dev slaptap16-2
           # ip route add 2401:5180:0:66:a300::/73 dev slaptap16-2 via 2401:5180:0:66:a300::1
      
      The second run with the same arguments looks as
      
          # ./pythonwitheggs ru/tapsplit slaptap16 2
          slaptap16: split 2401:5180:0:66:a200::/71 by 2
          preserve         2401:5180:0:66:a200::/73
          -> slaptap16-1   2401:5180:0:66:a280::/73
           # slaptap16-1: already exists
           # slaptap16-1: already up
           # slaptap16-1: already has 2401:5180:0:66:a280::/73 addr
           # slaptap16-1: already has 2401:5180:0:66:a280::1 route
           # slaptap16-1: already has 2401:5180:0:66:a280::/73 route
          -> slaptap16-2   2401:5180:0:66:a300::/73
           # slaptap16-2: already exists
           # slaptap16-2: already up
           # slaptap16-2: already has 2401:5180:0:66:a300::/73 addr
           # slaptap16-2: already has 2401:5180:0:66:a300::1 route
           # slaptap16-2: already has 2401:5180:0:66:a300::/73 route
      
      where it could be seen that no actions had been taken.
      
      And if, for example, the user manipulates slaptap16-2 and manually sets it
      down, the third run restores it to desired 'UP' state and readds the address
      and routes because the kernel removed them when link went down:
      
          # ip -6 addr show dev slaptap16-2
          157: slaptap16-2: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc fq_codel state DOWN group default qlen 1000

          # ip link set slaptap16-2 down

          -> slaptap16-1   2401:5180:0:66:a280::/73
           # slaptap16-1: already exists
           # slaptap16-1: already up
           # slaptap16-1: already has 2401:5180:0:66:a280::/73 addr

          -> slaptap16-2   2401:5180:0:66:a300::/73
           # slaptap16-2: already exists
           # ip link set slaptap16-2 up

      The first version of this patch tried to solve the problem by setting
      update-command to be noop instead of reworking tapsplit itself. But as Thomas
      noted this does not satisfy requirement "3".

      stack/erp5: implement Zope's rewrite rules in ERP5 balancer partition · 6e735808
      Jérome Perrin authored
      The strategy for compatibility is that:
       - haproxy still listen on the same port as before, without rewrite rule.
         This is called "legacy" port.
       - for each frontend from request parameters, we introduce an haproxy
         frontend with a rewrite for the corresponding `internal-path`
         parameter.
       - the shared frontend instance is updated to use this new frontend
         entry from haproxy. This will cause a small downtime until the shared
         frontend is updated to the new URL on ERP5, but since this feature
         was not used, it's OK.
      
      Technical details are that we:
       - split haproxy config to have frontends and backends.
       - introduce one frontend in haproxy for each frontend from request
         parameters.
       - routing-rule-list argument is still honored the same way, globally
         and after path from frontend.
       - change the shared frontend requests to use "" type, no longer "zope"
         type.
       - we don't do automatic detection of /VirtualHostRoot in URL but always
         add it, because it could be used to trick zope into thinking it
         serves requests for an arbitrary host and do open redirects
       - before using the request's host header in virtualhost path, we check
         that it does not contain /, to prevent injection of virutalhost path
         elements through the host header.
       - we don't use the "path" parameter from shared frontend, because we
         want the frontend to be simple, so we don't want it to rewrite the
         request path (which is also the reason why we deprecated "zope" type)
       - the tests have changed a lot, because they were using what's now the
         "legacy" URL types, so we updated it to use the new URL types with
         all the /VirtualHostRoot/../ in path and also because they use IPv6
         URL, no longer IPv4

      stack/erp5: use caucase managed certificate for balancer · d49914a6
      Jérome Perrin authored
      This reverts commit 620c9332 (stack/erp5: stop using caucase managed
      certificate for balancer, 2020-11-10) with an updated design. We add a
      caucase service for balancer in the balancer partition. The caucase
      service from the root partition (that was not used) is removed.
      
      The underlying idea is that the default configuration should use multiple
      caucases with limited scope, here we have one caucase to manage the
      certificate used by haproxy server in the balancer partition, so we put
      one caucase to manage this certificate and the caucase is configured to
      auto-accept one certificate only. The plan is that when we will add a
      certificate for mariadb server, we'll add another caucase inside this
      mariadb server.
      
      For more advanced usage and also to support the cases where a new
      certificate needs to be re-emitted for some reason, users can request
      with an existing caucase URL. In that case, they will have to accept
      the certificate requests.
      
      Notable changes:
      
      balancer/ssl/caucase-url is no longer documented in parameters, this is
      an internal parameter, users can pass one global caucase service to
      manage all partition
      
      CAUCASE environment variable is no longer set when running zope. There
      was no identified use case and with this new approach of multiple
      caucases, the term "caucase" alone became ambiguous.

      ERP5: rework frontend instance parameter · cb78214e
      Jérome Perrin authored
      This change the format or the (mostly) unused frontend parameter to
      support requesting more than one frontend and also enable the request of
      a frontend by default, so that requesting a frontend separately is no
      longer needed.
      
      The `frontend` parameter now also supports requesting frontends for
      specific paths on the ERP5 backend, the example below requests a
      frontend serving directly a web site, with the necessary rewrite rules:
      
      ```js
      {
        "frontend": {
          "default": {
            "internal-path": "/erp5/web_site_module/renderjs_runner/"
          }
        }
      }
      ```
      
      The example below requests a default frontend to the erp5 root, to
      access the ZMI or erp5_xhtml_style interface and two web sites:
      
      ```js
      {
        "frontend": {
          "default": {},
          "erp5js": {
            "internal-path": "/erp5/web_site_module/renderjs_runner/"
          },
          "crm": {
            "internal-path": "/erp5/web_site_module/erp5_officejs_support_request_ui/"
          }
        }
      }
      ```
      
      The example below has an explicit definition of the zope families using
      `zope-partition-dict` parameter, because there is more than one zope
      family, no frontend is requested by default:
      
      ```js
      {
        "zope-partition-dict": {
          "backoffice": {
            "family": "backoffice"
          },
          "web": {
            "family": "web"
          },
          "activities": {
            "family": "activities"
          }
        }
      }
      ```
      
      Continuing this example, to have frontends for backoffice and web
      families, the frontend request can specify the families, like it is
      demonstrated in the example below. In this example, we don't specify an
      entry for "activities" family, so no frontend will be requested for
      this family.
      
      ```js
      {
        "frontend": {
          "backoffice": {
            "zope-family": "backoffice"
          },
          "web": {
            "zope-family": "web",
            "internal-path": "/erp5/web_site_module/web_site/"
          }
        }
        "zope-partition-dict": {
          "backoffice": {
            "family": "backoffice"
          },
          "web": {
            "family": "web"
          },
          "activities": {
            "family": "activities"
          }
        }
      }
      ```

      Rework UEsim to be able to work with multiple cells, multiple radio units(*),
      multiple UE all at the same time. RU, CELLs and UEs are now configured,
      simiularly to eNB, via shared instances. Add tests.
      
      Contrary to ORS don't care about backward compatibility here because currently
      we have just a few UEsim deployments and migrating them should be easy.
      
      Please see added schemas, tests and updates slapos-render-config on how to use
      the new system.
      
      (*) contrary to eNB UEsim does not allow to use one RU for two cells,

      software/ors-amarisoft: enb: Try to support NR/FDD a bit · 4abb4101
      Kirill Smelkov authored
      It should be already generally supported, but many parameters needs in NR case
      are currently hardcoded to their TDD values. I've adjusted only a few of them
      and stopped, becuase there is currently no practical case at hand for me to
      test it. Still I think it makes sense to save this first step.
      
      For ORS, who uses TDD, rendered config stays practically the same:
      
      ```
      $ ./pythonwitheggs slapos-render-config.py && xdiff -C -C config/{old,out}/ors/

      software/ors-amarisoft: enb: Intra-ENB handover · 5c300a7d
      Kirill Smelkov authored
      If a base station has multiple cells, it should be possible for UE to be handed
      over from one cell into another, for example when UE crosses border of sectors.
      
      So far we had only Inter-ENB HO and now we are also adding configuration for
      HO in between all own cells.
      
      Add tests for everything.
      
      NOTE: we use allowed_meas_bandwidth, antenna_port_1 in dst=LTE case because
      otherwise, e.g. for NR->LTE HO if they are not present, lteenb complains:
      
          enb.cfg:260: expecting 'allowed_meas_bandwidth' field
          enb.cfg:260: expecting 'antenna_port_1' field
      
      for both Intra-ENB and Inter-ENB handovers.
      
      For Intra-ENB case we can compute those numbers from cell definition. For
      Inter-ENB case, when we don't know target context, we use conservative values.

      software/ors-amarisoft: enb: Take frequencies control into our hands · 37b1b28d
      Kirill Smelkov authored
      Currently when setting up cells we allow users to input
      
      - dl_earfcn for LTE, and
      - dl_nr_arfcn and nr_band for NR
      
      and from that lteenb automatically computes
      
      - ul_earfcn for LTE, and
      - ul_nr_arfcn and ssb_nr_arfcn for NR
      
      everything kind of works out of the box for eNB case when there is simple SDR Radio Unit.
      
      Then there are also the following cases:
      
      1. we also need to set UL frequency when configuring Lopcomm RU, or any other ORAN-based Radio Unit.
      2. we also need to specify DL/UL frequencies in MHz when configuring Lopcomm RU.
      3. when configuring NR peercell it is required to set ssb_nr_arfcn. It is also
         required to set both dl_nr_arfcn and ul_nr_arfcn, and so far we were setting
         only DL one and using it for both assuming TDD band.
      4. when configuring UEsim we need to specify both dl_nr_arfcn and ssb_nr_arfcn for NR cells.
      
      So the problem is that even though lteenb automatically computes UL and SSB
      frequencies, there is no way for us to reuse results of that computation for
      scenarios outside of "simple enb" case.
      
      As the result we kind of workaround that currently with exposing additional
      parameters and asking users to look into enb, probably its `cell phy` output,
      with the following:
      
           ---- 8< ---- (from UEsim)
           "ssb_nr_arfcn": {
             "title": "SSB NR ARFCN",
             "description": "SSB NR ARFCN, you can retrieve from ENB/GNB side",
      
      or use additional parameters just for ul_earfcn and frequency-in-MHz:
      
           ---- 8< ---- (from ru/lopcomm)
           "txa0cc00_center_frequency": {
             "title": "Lopcomm ORAN DL Center Frequency in MHz (TXA0CC00)",
             "description": "Lopcomm ORAN Center Frequency in MHz (TXA0CC00)",
             "type": "number",
             "default": 2140
           },
           "rxa0cc00_center_frequency_earfcn": {
             "title": "Lopcomm ORAN UL Center Frequency EARFCN (RXA0CC00)",
             "description": "Lopcomm ORAN Center Frequency EARFCN (RXA0CC00)",
             "type": "number",
             "default": 18300
           },
           "rxa0cc00_center_frequency": {
             "title": "Lopcomm ORAN UL Center Frequency in MHz (RXA0CC00)",
             "description": "Lopcomm ORAN Center Frequency in MHz (RXA0CC00)",
             "type": "number",
             "default": 1950
           },
      
      which prevents automation, opens the door for inconsistencies and puts the load
      to resolve all that on users.
      
      The root cause of the problem is that there is no way to access at
      instantiation time what lteenb would compute internally. But DL<->UL conversion
      and DL->SSB conversion is not a difficult task and we can do that on our own.
      
      -> Do that here and solve all the problems listed above in one go.
      
      For frequency computations we use my xlte.earfcn and xlte.nrarfcn modules and
      upstream nrarfcn egg. For this xlte is updated(*) to primarily pick up
      
      kirr/xlte@6cb9d37f
      kirr/xlte@b8065120
      
      and the rest of the conversion is in slaplte to use corresponding dl2ul and
      dl2ssb routines.
      
      For consistency ul_earfcn and ul_nr_arfcn now become input parameters for LTE
      and NR cells, but optional. If they are absent - they are computed with
      defaults, but a user can now control them explicitly. The same applies for
      ssb_nr_arfcn.
      
      This patch does not convert UEsim yet, because UEsim does not use rulib yet and
      will be handled all in one go in a follow-up step.
      
      The computation routines are thoroughly tested. First they have unit tests
      inside XLTE itself, then we also update our tests in generic test/test.py here
      with explicitly checking that correct numbers are emitted for UL and SSB
      frequencies, and third I've also verified SSB computation results with respect
      to https://tech-academy.amarisoft.com/OutOfBox_UEsim_SA.html#Tips_SSB_Frequency .
      
      All this creates a base to be sure that the computations are correct and we are
      indeed safe to switch our frequencies computation modules.
      
      (*) full upgrade brings kirr/xlte@e716ab51...8e606c64 ;

      Kirill Smelkov authored
      So far in the unit tests we were only generating enb.cfg without semantically
      processing as running lteenb is not possible on testnodes due to licensing
      restrictions. That allowed to use arbitrary numbers, even invalid, for
      frequencies without hitting an error.
      
      However in the next patch we are going to start handling frequencies ourselves,
      and invalid frequencies will lead to instantiation failures like
      
          ... in dl2ul(dl_earfcn)
          KeyError: 'no band that corresponds to DL EARFCN=325320'
      
      Avoid that by switching to valid LTE and NR frequency numbers in the test.

      Radio Units like Lopcomm ORAN require explicit activation for the radio.

      For example if we need to do 4T4R but have SDR boards with only 2T2R ports, we

      software/ors-amarisoft: enb/generic: Protect from buildout code injection · c83fa3cb
      Kirill Smelkov authored
      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.

      this topic:

      Kirill Smelkov authored
      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.

      software/ors-amarisoft: slapos-render-config: Add peers · 69602afe
      Kirill Smelkov authored
      We already have peer cells in the setup of generated enb/gnb, but there were no
      X2/XN peers there. Add them to be able to see how handling of peers works.
      
      Rendered files change as expected:
      
      ```
      $ ./pythonwitheggs slapos-render-config.py && xdiff config/{old,out}
      ```
