oauth2_proxy/CHANGELOG.md

Vx.x.x (Pre-release)

Changes since v4.0.0

#258 Add IDToken for Azure provider

• This PR adds the IDToken into the session for the Azure provider allowing requests to a backend to be identified as a specific user. As a consequence, if you are using a cookie to store the session the cookie will now exceed the 4kb size limit and be split into multiple cookies. This can cause problems when using nginx as a proxy, resulting in no cookie being passed at all. Either increase the proxy_buffer_size in nginx or implement the redis session storage (see https://pusher.github.io/oauth2_proxy/configuration#redis-storage)

v4.0.0

Release Highlights

• Documentation is now on a microsite
• Health check logging can now be disabled for quieter logs
• Authorization Header JWTs can now be verified by the proxy to skip authentication for machine users
• Sessions can now be stored in Redis. This reduces refresh failures and uses smaller cookies (Recommended for those using OIDC refreshing)
• Logging overhaul allows customisable logging formats

Important Notes

• This release includes a number of breaking changes that will require users to reconfigure their proxies. Please read the Breaking Changes below thoroughly.

Breaking Changes

• #231 Rework GitLab provider
  • This PR changes the configuration options for the GitLab provider to use a self-hosted instance. You now need to specify a -oidc-issuer-url rather than explicit -login-url, -redeem-url and -validate-url parameters.
• #186 Make config consistent
  • This PR changes configuration options so that all flags have a config counterpart of the same name but with underscores (_) in place of hyphens (-). This change affects the following flags:
  • The --tls-key flag is now --tls-key-file to be consistent with existing file flags and the existing config and environment settings
  • The --tls-cert flag is now --tls-cert-file to be consistent with existing file flags and the existing config and environment settings This change affects the following existing configuration options:
  • The proxy-prefix option is now proxy_prefix. This PR changes environment variables so that all flags have an environment counterpart of the same name but capitalised, with underscores (_) in place of hyphens (-) and with the prefix OAUTH2_PROXY_. This change affects the following existing environment variables:
  • The OAUTH2_SKIP_OIDC_DISCOVERY environment variable is now OAUTH2_PROXY_SKIP_OIDC_DISCOVERY.
  • The OAUTH2_OIDC_JWKS_URL environment variable is now OAUTH2_PROXY_OIDC_JWKS_URL.
• #146 Use full email address as User if the auth response did not contain a User field
  • This change modifies the contents of the X-Forwarded-User header supplied by the proxy for users where the auth response from the IdP did not contain a username. In that case, this header used to only contain the local part of the user's email address (e.g. john.doe for john.doe@example.com) but now contains the user's full email address instead.
• #170 Pre-built binary tarballs changed format
  • The pre-built binary tarballs again match the format of the bitly repository, where the unpacked directory has the same name as the tarball and the binary is always named oauth2_proxy. This was done to restore compatibility with third-party automation recipes like https://github.com/jhoblitt/puppet-oauth2_proxy.

v3.1.0

Release highlights

• Introduction of ARM releases and and general improvements to Docker builds
• Improvements to OIDC provider allowing pass-through of ID Tokens
• Multiple redirect domains can now be whitelisted
• Streamed responses are now flushed periodically

Important notes

• If you have been using #bitly/621 and have cookies larger than the 4kb limit, the cookie splitting pattern has changed and now uses _ in place of - when indexing cookies. This will force users to reauthenticate the first time they use v3.1.0.
• Streamed responses will now be flushed every 1 second by default. Previously streamed responses were flushed only when the buffer was full. To retain the old behaviour set --flush-interval=0. See #23 for further details.

  • Implement pass-authorization-header and set-authorization-header flags
  • Implement token refreshing in OIDC provider
  • Split cookies larger than 4k limit into multiple cookies
  • Implement token validation in OIDC provider
• #15 WhitelistDomains (@joelspeed)
  • Add --whitelist-domain flag to allow redirection to approved domains after OAuth flow
• #21 Docker Improvement (@yaegashi)
  • Move Docker base image from debian to alpine
  • Install ca-certificates in docker image
• #23 Flushed streaming responses
  • Long-running upstream responses will get flushed every (1 second by default)
• #24 Redirect fix (@agentgonzo)
  • After a successful login, you will be redirected to your original URL rather than /
• #35 arm and arm64 binary releases (@kskewes)
  • Add armv6 and arm64 to Makefile release target
• #37 cross build arm and arm64 docker images (@kskewes)
