Guiding principles

  • Code quality
  • Developer experience (including modularity)
  • End-user experience
  • Administrator experience
  • Performance
  • Protocol evolution

Current roadmap items

This list will probably eventually be superseded by the KRB JIRA backlog. Target releases for roadmap items are subject to change.

krb5-1.15

krb5-1.16

Long-term roadmap items

Code quality

  • Move toward test-driven development
  • Increase conformance to coding style
    • Selective refactoring
    • Continue formatting cleanup
  • Use cyclomatic complexity metrics to identify cleanup targets

Developer experience

  • Crypto modularity -- make sure PKCS#11 etc. work well
  • API documentation
  • Support readily building subsets
    • "Lite" client
    • "Lite" server
  • KDC Database modularity (long-term)
    • SQLite back end
    • Does the existing DAL make sense?
    • Make data model less "blobby"
    • Track IETF data model work
  • Plugin support improvements
    • GSS-API mechanism glue
    • DNS / host-to-realm mapping
  • Secure co-processor ("would be nice")
  • GSS proxy
  • interposition capability for GSS mechs (useful for GSS proxy) -- external for 1.11
  • Use default keytab for gss_init_sec_context
  • gss_export_cred (useful for async GSS proxy)
  • Improve ASN.1 support code (better support for plugins that need to encode/decode their own ASN.1 types)

End-user experience

  • Improve credential management

Administrator Experience

  • Plugin for kadmin authorizations
  • Move more realm-global configuration into KDB
  • Add interface to purge old keys (1.8 patch?)
  • Add interface to delete keys of specific enctypes (1.8 patch?)
  • Disable enctypes at compile time (1.8 patch?)
  • Improve IPv6 support
  • Improve key rollover
    • Application service keys
  • Decrease DNS-related fragility
  • Plugins for login failure lockout
  • Plugins for audit support
  • Plugins for ticket issuance access control
  • Plugins for domain-realm mapping
  • Friendlier smart card support
  • FAST OTP client in libkrb5 (maybe excluding second-level plugins hardware OTP tokens)
  • Multiple logging levels for trace logging

Performance

  • Decrease DNS traffic
  • Client resolution of KDC (etc.) addresses can be very slow. Decouple address resolution from initiation of KDC communications. (requires some redesign of internal interfaces)
  • Replay cache ("rcache")
    • Improve implementation
    • Support disabling by service type name
  • Enhancements to improve concurrency
    • Explicit state
    • Reduce mutex contention
    • Support asynchronous APIs and frameworks such as Apple's Grand Central Dispatch; begin refactoring code to make this easier

Protocol evolution

  • International strings in protocol (need IETF feedback)
    • Principal names
    • Error strings, etc. (need language tag negotiation)
  • Timestamp-independence
  • Replay-proofing protocols
  • Encryption algorithm updates (SHA-2, SHA-3, CCM, GCM)
  • PKU2U
  • One time password support
  • Multiply-authenticated authorization data container
  • POSIX IDs in authorization data
  • Level of Assurance in authorization data
  • Site-defined string-keyed claims in authorization data
  • X.509 attributes in authorization data
  • FAST preauth sets (e.g. OTP + long-term password)
