Minutes/Updates

• Make repo config into the json config and support local file
  • Where is the json .cfg?
  • The comments are the only docs we have for the config.
    • Would be nice to have a doc for this
• When should PRs be approved how many approvals needed?
  • 2 separate from the submitter
• `Monitoring the expiration of TLS certs.
  • Added configurable warning
  • 30 day warning by default
• Running L3AFd on Azure VM.
  • use port 8080
  • clone l3afd repo run go install
  • Use port 7080
  • Change the port
• Roadmap and Release schedule Initial
  • Release will increase our badging score
  • What are the big rocks?
    • mTLS
      • Trust based on CA
      • Trust if it's signed by CA and matches pattern
    • define repos per eBPF package
      • Atul working on this now
    • Security RBAC - Read only user vs. Admin.
  • Having L3AFD running on an Azure VM in Windows and Linux
  • Running rate limiting and XDP root on Windows
  • Signed eBPF programs(?) - Stretch goal.
  • Multiple repo support.
  • mTLS - key should never be in the source code or a cfg.
    • Could be in a separate file that only the l3afd user can access it.
    • Use cloud services for prod.
    • Every time we generate a new token.
    • Client can use the token until we regenerate
    • Sign token for read user then that is part of the hash
    • the role is signed in the token.
    • If we have a token with the assigned role then we can auth and validate the user.
    • Use local file store for dev and cloud provider option for prod.
  • Timeframe:
    • 1-2 months
• Thoughts about release cadence
  • Every 2-3 months(?) - too aggressive
  • Let's try 6 months for starters.
    • Eventually go to quarterly
• Long term roadmap
  • Chaining semantics
    • Cilium has their own semantics
    • Standardize XDP dispatcher
      • Have multiple progs attach to interface on XDP
      • Approach is impossible on the TC side
        • Testing now.
      • lib XDP convert into golang
      • directly call APIs from l3afd
      • Newer version of prog with mult eBPF progs attached in priority
      • l3af chaining and Cilium not compat.
        • Should we change our semantics?
          • tracking progs and maps
        • Should be seamless in kube environment
      • desktop apps for l3afd
        • Running on service
  • Looking at using core. (Linux Kernel)
    • write eBPF progs to leverage core semantics across different kernel releases
    • Move everything to latest libBPF
    • Move to latest libBPF APIs
  • Package signing
