      caddy-frontend: Put back certificates to input schemas · 05b1d215
      Łukasz Nowak authored
      In "caddy-frontend: Implement KeDiFa SSL information" the certificates were
      dropped from the schema, but still internally supported. This lead to missing
      UI fields for still supported parameters.
      
      Reintroduced them with OBSOLETE mark.

      caddy-frontend: Switch AIKC to default true · a198be7f
      Łukasz Nowak authored
      It is better to have automation similar to previous implementation by
      default.

      AIKC - Automatic Internal Kedifa's Caucase CSR signing, which can be triggered
      by option automatic-internal-kedifa-caucase-csr.
      
      It signs all CSR which match csr_id and certificate from the nodes which needs them.

      caddy-frontend: Implement KeDiFa SSL information · bc2b1742
      Łukasz Nowak authored
      Use KeDiFa to store keys, and transmit the url to the requester for master
      and slave partitions.
      
      Download keys on the slave partitions level.
      
      Use caucase to fetch main caucase CA.
      
      kedifa-caucase-url is published in order to have access to it.
      
      Note: caucase is prepended with kedifa, as this is that one.
      
      Use kedifa-csr tool to generate CSR and use caucase-updater macro.
      
      Switch to KeDiFa with SSL Auth and updated goodies.
      
      KeDiFa endpoint URLs are randomised.
      
      Only one (first) user certificate is going to be automatically accepted. This
      one shall be operated by the cluster owner, the requester of frontend master
      partition.
      
      Then he will be able to sign certificates for other users and also for
      services - so each node in the cluster.
      
      Special trick from https://security.stackexchange.com/questions/74345/provide-subjectaltname-to-openssl-directly-on-command-line
      is used for one command generation of extensions in the certificate.
      Note: We could upgrade to openssl 1.1.1 in order to have it really
      simplified (see https://security.stackexchange.com/a/183973 )
      
      Improve CSR readability by creating cluster-identification, which is master
      partition title, and use it as Organization of the CSR.
      
      Reserve slots for data exchange in KeDiFa.

      caddy-frontend: Fix random 502 EOFs by adding try_duration · 4f168972
      Łukasz Nowak authored
      try_duration and try_interval are Caddy proxy's switches which allow to deal
      with non working backend (https://caddyserver.com/docs/proxy)
      
      The non working backend is the one, to which connection is lost or was not
      possible to make, without sending any data.
      
      The default try_duration=5s and try_interval=250ms are chosen, so that in
      normal network conditions (with all possible problems in the network, like
      lost packets) the browser will have to wait up to 5 seconds to be informed
      that backend is inaccessible or for the request to start being processed,
      but only a bit more than 250ms if Caddy would have to reestablish connection
      to faulty backend.
      
      In order to check it out it is advisable to setup a system, with real backend,
      like apache one, and configure iptables to randomly reject packets to it:
      
        iptables -A INPUT -m statistic --mode random -p tcp --dport <backend_port> \
        --probability 0.05 -j REJECT --reject-with tcp-reset
      
      Using ab or any other tool will results with lot of 502 EOF in the Caddy error
      log and also reported by ab. With this configuration there are no more
      errors visible to the client, which come from the problems on the network
      between Caddy and the backend.
