release 2.4.16.6

Bugfixes

• metadata: fix caching of JWKs from jwks_uri when using the default expiry setting (i.e. not using OIDCJWKSRefreshInterval) and avoid fetching JWKs from the jwks_uri for each user login; also addresses Redis cache error entries the log [ERR invalid expire time in 'setex' command] (regression in 2.4.16-2.4.16.5)
• info: fix requests to the info hook with extend_session=false; see #1279; thanks @fnieri-cdp
  • properly reflect the (unmodified) inactivity timeout in the response (in thetimeout claim)
  • avoid refreshing an access token (since the session is not saved)
  • avoid refreshing claims from the user info endpoint, and possibly refreshing the access token
• cookie: OIDCCookieSameSite default behaviour Lax
• cookie: apply OIDCCookieSameSite Off/None properly to state cookies instead of always setting Lax
• cache: avoid segfault and improve error reporting in case apr_temp_dir_get fails when a temp directory cannot be found on the system upon initaliizing cache mutexes and the file cache; see #1288; thanks @ErmakovDmitriy

Features

• cookie: allow specific settings Strict|Lax|None|Disabled for OIDCCookieSameSite in addition to On(=Lax)|Off(=None)
  • re-introduces the option to configure a Strict SameSite session cookie policy, which will turn the initial Lax session cookie - set upon receving the response to the Redirect URI - into a Strict session cookie immediately after the first application request
  • cookie: allows for a Disabled value that does not set any SameSite flag on the cookies, in which case a browser falls back to its default browser behaviour (which should be Lax by spec)
• http: add option to set local address for outgoing HTTP requests; see #1283; thanks @studersi using e.g. SetEnvIfExpr true OIDC_CURL_INTERFACE=192.168.10.2

Other

• metadata: allow plain HTTP URLs in metadata elements jwks_uri and signed_jwks_uri to ensure backwards compatibility with <=2.4.15.7 and to support private/test deployments
• code: address warnings from static code analysis tool CodeChecker
• init: try and address metris cleanup segmentation fault on shutdown; see #1207 by not flushing metrics to the shared memory segment upon exit
