      software/headless-chromium: Update chromium to 114.0.5735.340 · 4cd01085
      Jérome Perrin authored
      We had to introduce a web page to bootstrap the web version of devtools
      because since https://bugs.chromium.org/p/chromium/issues/detail?id=1232509
      chrome debugger port no longer serve such a page via HTTP.
      
      The URL also changed, /serve_file/@{version_hash}. pattern is no longer
      used, both the devtools and the websocket endpoint are in /devtools
      
      The test was made a bit more complete by actually making requests and
      trying to connect to websocket endpoints.
      
      Some problems were found with incognito and block-new-web-contents
      options:
       - they are boolean type, but the software parameter serialisation is
       XML, which as of today does not support boolean types. This is left
       TODO for now
       - When both --incognito and --block-new-web-contents are true, the
       command line flag was --incognito--block-new-web-contents, which is
       unknown and was ignored. Some minmal changes are included to fix this.

      software/ors-amarisoft: enb: Adjust DHCP server to provide dedicated IPv6 to each Radio Unit · cbc3929c
      Kirill Smelkov authored
      By reusing recently added "split TAP" infrastructure we can adjust dnsmasq
      configuration to provide unique IPv6 to each RU.
      
      - ru_mac_addr becomes per-RU setting and without default. We talked with Lu, and
        since now all Lopcomm units are shipped from the factory with unique MAC, it
        both does not make sense to provide the default, and we can rely on all units
        to have different MACs and configure DHCP replies based on that.
      
      - No need to provide /64 network to every RU. We cannot actually do that anyway
        because normally SlapOS provides /71 address range for its slaptap. In the
        new configuration everything works with smaller networks just ok.

      software/ors-amarisoft: enb: Remove DNS options from for-RU DHCP configuration · 30b4cec5
      Kirill Smelkov authored
      Those options are not needed, because we need to only provide IPv6 address to
      RU, and also they are not very meaningful: in the current form we tell RU that
      DNS addresses sit at RU.addr+1 and RU.addr+2, i.e. in the IP range we give to
      RU and also at the addresses where no DNS server is actually running.
      
      It was probably a thinko to add those options initially.

      software/ors-amarisoft: Split dnsmasq.cfg into for-core and for-enb · 9f2b9db5
      Kirill Smelkov authored
      Core Network and ENB use dnsmasq for completely different purposes:
      
      - core network uses it to provide DNS server, while
      - enb uses dnsmasq to provide DHCP server for Radio Units to be able to access
        Control & Management channel on the CPRI link.
      
      -> Even though both those services are handled via same dnsmasq program, it
         makes sense to split dnsmasq config for clarity and as preparation for
         further adjustments of enb part.
      
         We also push config rendering down to -core and -enb instances also for
         clarity, and because in enb case rendering will need to know set of
         configured Radio Units - information that will become loaded only at
         instance-enb.

      software/ors-amarisoft: Provide dedicated TAP interface for each Radio Unit · 49ce8ef5
      Kirill Smelkov authored
      SlapOS provides to each partition dedicated TAP interface, so that an instance
      could organize internal networking. In practice this is used by KVM software
      release and here in ors-amarisoft, where we feed to eNB such TAP interface for
      CPRI-based radio unit so that eNB, in turn, could provide access to CPRI
      Control and Management channel via provided TAP.
      
      However there is a problem: SlapOS provides only one TAP interface per
      instance, while we need to have one TAP for each Radio Unit.
      
      -> Solve this problem by creating TAP "subinterfaces" per each RU ourselves.
      
      The interfaces we create are full TAP interfaces, just we name them with prefix
      based on main interface, and we allocate only part of address space of sole
      SlapOS TAP to each subtap. For example if SlapOS provided us slaptap16 with
      2401:5180:0:66:a200::/71 IPv6 range and we want to split it for 2 radio units,
      we'll be splitting it into 3 regions as follows:
      
          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
          -> slaptap16-2   2401:5180:0:66:a300::/73
      
      Here we preserve 2401:5180:0:66:a200::/73 for usage on original slaptap16, and
      we create slaptap16-1 and slaptap16-2 with correspondingly allocated address
      range subparts for the RUs.
      
      The splitting is done easily but depends on having networking administration
      capability to be able to work. We solve this with employing
      /opt/amarisoft/setcap, which we already use for dnsmasq, and with compiled
      trampoline program because setcap does not really work directly on scripts.
      
      To avoid hard dependency on having network capability rights, we fallback to
      using regular SlapOS slaptap in case there is only one RU.
      
      ru/lopcomm/* and enb.cfg are adapted straightforwardly, but dnsmasq adaptation
      is left to a later step not to mix everything into one pile.
      
      NOTE that relying on setcap is not a good in the long term and should be
           reworked once SlapOS is improved to provide ability for instances to
           request several TAP interfaces. Please see discussion at
           nexedi/slapos!1471 (comment 194356)
           for details.
