  • OpenID Federation -work

  • https://shibboleth.atlassian.net/browse/JOIDC-226

    • Spring CORS Configuration handles both the preflight and the actual requests (containing Origin-header)

      • The currently existing hook (shibboleth.CorsConfigurations) is a static list - the p:allowedOrigins doesn’t scale

        • Dynamic hook shibboleth.CorsConfigurationsSource in IdP 5.2 via IDP-2338

        • The preflight request contains the Origin-header, but not client_id - most of the metadata resolvers can be queried without entity ID criterion, but not all (e.g. local dynamic)

      • The simplest approach is to provide plugin-specific CORS Configuration -documentation, containing the required manual steps

        • The (plugin) flows can perform more fine-grained Origin-header validation after metadata resolution

      • Perhaps another option would be to provide e.g. auto-wiring hooks for the dynamic shibboleth.CorsConfigurationsSourcein IdP

  • https://shibboleth.atlassian.net/wiki/spaces/DEV/pages/4629659652 is mostly done now:

    • All public working repositories are now canonically hosted on Codeberg and mirrored back to git.shibboleth.net.

    • Inactive repositories are now locked and are no longer mirrored.

    • I added a script (fixremote) to the migration page to make it a little easier to convert your local workspaces. Here’s a copy:

    • Exceptions: personal repositories, gitolite-config, infra-pgpkeys, java-idp-plugin-mgmt.

    • The mail to committers seems to be working again but we don’t know why. If that persists, I will retire the other mechanism.

    • One disruption between the two mail streams seems to come from signed commits. In general I don’t see the point in signed commits in general (they break if you need to rebase or cherry-pick) but specifically any push containing a signed commit does not appear in Codeberg’s activity feed. This is probably a bug, but for the moment I suggest not using this Git feature with our repositories, with the possible exception of infra-gpgkeys. I think this only affects Tom, and only in the last couple of days, but by definition it’s hard for me to tell.

    • There’s an API we can use to do any further per-repository configuration instead of doing everything manually.

    • Next steps: migrate the two repositories with hooks.

No updates.

Phil

  • Minor RP-Proxy and WebAuthn work

  • OIDC SP Work:

    • Token exchange is working, signature verification and decryption is wired up.

      • Some of the validators have been disabled until I go back to looking at what gets carried in the state

    • UserInfo profile claims lookup is working. Similar to token exchange wr.t. to the security checks currently enabled

    • Extracting claims and filtering is in place; need to add the attribute resolver

    • The response is added back to the DDF ready to be transferred back to the agent

      • Only the basics atm. No extract session data yet.

    • Will make sure the verification and validation is all working next.

 

Rod

  • Nothing. Life is getting in the way. Like to continue through the new year

  • Jetty plugin: shaping up nice. Thanks to Scott and Steven

  • SP. I would like to start poking at Wix6 next week (I am envisioning the simplest possible, GUI free, install at least for Alpha)

Scott

  • Jetty plugin testing and docs for Linux, though I tested with a Mac

    • Pending objections, we will default to 8080/8443 on 127.0.0.1 only

  • SP documentation

    • Hub material complex but coming along, mostly through the intermediate material, no real reference work done yet, or much on security config (i.e. keys)

    • Don’t think it’s a good idea to duplicate most of the existing IdP material where services are reused, but it would eventually be an opportunity to revisit a lot of that for better approachability from both perspectives

    • “Maybe” good enough for an alpha at this point? Not easy for me to assess.

  • https://shibboleth.atlassian.net/browse/CPPSP-37

  • Major concerns that could disrupt plans

    • Load testing the file session cache and the WinHTTP remoting

      • Suspect default session cache will end up being remoted to Hub StorageService anyway until/unless a cookie option is viable/implemented, so don’t know how much I care about the filesystem working

      • WinHTTP fallback is not Curl because that would mean building, linking, maintaining libcurl, openssl, zlib, which is out of the question
