From cc88f1dd6245ae572b54822b23f0ef685d0118e3 Mon Sep 17 00:00:00 2001 From: "Nick A. Smith" Date: Tue, 1 May 2018 17:48:25 +0100 Subject: [PATCH 1/2] Split JWT verification from forwarding. Splitting logic previously in jwt_authenticator into 2 parts. - jwt_authenticator just contains logic for verifying/authenticating JWTs - JWT forwarding logic has been moved into jwt_auth filter. The changes enable greater re-usability of the JWT verification code across filters. All tests updated and passing. --- WORKSPACE | 4 +- istio.deps | 2 +- src/envoy/http/authn/BUILD | 2 +- src/envoy/http/authn/authn_utils.cc | 4 +- src/envoy/http/jwt_auth/BUILD | 94 +--- src/envoy/http/jwt_auth/http_filter.cc | 95 +++- src/envoy/http/jwt_auth/http_filter.h | 28 +- .../http/jwt_auth/http_filter_factory.cc | 20 +- src/envoy/http/jwt_auth/http_filter_test.cc | 226 +++++++++ .../jwt_auth/integration_test/envoy.conf.jwk | 28 +- ...envoy_allow_missing_or_failed_jwt.conf.jwk | 26 +- .../http_filter_integration_test.cc | 10 +- src/envoy/http/jwt_auth/jwt_authenticator.cc | 247 ---------- src/envoy/http/mixer/check_data.cc | 13 +- src/envoy/http/mixer/filter_factory.cc | 1 + src/envoy/tcp/mixer/filter_factory.cc | 1 + src/envoy/utils/BUILD | 81 ++++ .../{http/jwt_auth => utils}/auth_store.h | 27 +- src/envoy/utils/constants.cc | 30 ++ src/envoy/utils/constants.h | 28 ++ src/envoy/{http/jwt_auth => utils}/jwt.cc | 51 +- src/envoy/{http/jwt_auth => utils}/jwt.h | 86 ++-- src/envoy/utils/jwt_authenticator.cc | 205 ++++++++ .../jwt_auth => utils}/jwt_authenticator.h | 62 +-- .../jwt_authenticator_test.cc | 453 ++++++------------ .../{http/jwt_auth => utils}/jwt_test.cc | 199 ++++---- .../{http/jwt_auth => utils}/pubkey_cache.h | 22 +- .../jwt_auth => utils}/token_extractor.cc | 35 +- .../jwt_auth => utils}/token_extractor.h | 46 +- .../token_extractor_test.cc | 132 ++--- src/envoy/utils/tools/generate_test_jwts.sh | 101 ++++ .../jwt_auth => utils}/tools/jwk_generator.py | 0 .../jwt_auth => utils}/tools/jwt_generator.py | 20 +- 33 files changed, 1341 insertions(+), 1038 deletions(-) create mode 100644 src/envoy/http/jwt_auth/http_filter_test.cc delete mode 100644 src/envoy/http/jwt_auth/jwt_authenticator.cc rename src/envoy/{http/jwt_auth => utils}/auth_store.h (74%) create mode 100644 src/envoy/utils/constants.cc create mode 100644 src/envoy/utils/constants.h rename src/envoy/{http/jwt_auth => utils}/jwt.cc (92%) rename src/envoy/{http/jwt_auth => utils}/jwt.h (85%) create mode 100644 src/envoy/utils/jwt_authenticator.cc rename src/envoy/{http/jwt_auth => utils}/jwt_authenticator.h (54%) rename src/envoy/{http/jwt_auth => utils}/jwt_authenticator_test.cc (59%) rename src/envoy/{http/jwt_auth => utils}/jwt_test.cc (73%) rename src/envoy/{http/jwt_auth => utils}/pubkey_cache.h (89%) rename src/envoy/{http/jwt_auth => utils}/token_extractor.cc (75%) rename src/envoy/{http/jwt_auth => utils}/token_extractor.h (70%) rename src/envoy/{http/jwt_auth => utils}/token_extractor_test.cc (64%) create mode 100755 src/envoy/utils/tools/generate_test_jwts.sh rename src/envoy/{http/jwt_auth => utils}/tools/jwk_generator.py (100%) rename src/envoy/{http/jwt_auth => utils}/tools/jwt_generator.py (86%) diff --git a/WORKSPACE b/WORKSPACE index b864fa6513a..086986527d6 100644 --- a/WORKSPACE +++ b/WORKSPACE @@ -38,12 +38,12 @@ git_repository( ) # When updating envoy sha manually please update the sha in istio.deps file also -ENVOY_SHA = "2b2c299144600fb9e525d21aabf39bf48e64fb1f" +ENVOY_SHA = "a9bcb26375658a505e19938f4816a92d6e338053" http_archive( name = "envoy", strip_prefix = "envoy-" + ENVOY_SHA, - url = "https://github.com/envoyproxy/envoy/archive/" + ENVOY_SHA + ".zip", + url = "https://github.com/thalesignite/envoy/archive/" + ENVOY_SHA + ".zip", ) load("@envoy//bazel:repositories.bzl", "envoy_dependencies") diff --git a/istio.deps b/istio.deps index d646d377bc2..65d36613383 100644 --- a/istio.deps +++ b/istio.deps @@ -11,6 +11,6 @@ "name": "ENVOY_SHA", "repoName": "envoyproxy/envoy", "file": "WORKSPACE", - "lastStableSHA": "2b2c299144600fb9e525d21aabf39bf48e64fb1f" + "lastStableSHA": "2eb5bd5acc11a88f7c284ebc0eb7d40c27a93e2d" } ] \ No newline at end of file diff --git a/src/envoy/http/authn/BUILD b/src/envoy/http/authn/BUILD index 6c9efa35324..d9697fbd38f 100644 --- a/src/envoy/http/authn/BUILD +++ b/src/envoy/http/authn/BUILD @@ -43,7 +43,7 @@ envoy_cc_library( repository = "@envoy", deps = [ "//external:authentication_policy_config_cc_proto", - "//src/envoy/http/jwt_auth:jwt_lib", + "//src/envoy/utils:jwt_lib", "//src/envoy/utils:utils_lib", "//src/istio/authn:context_proto", ], diff --git a/src/envoy/http/authn/authn_utils.cc b/src/envoy/http/authn/authn_utils.cc index 78c232e3108..bf0ed948c34 100644 --- a/src/envoy/http/authn/authn_utils.cc +++ b/src/envoy/http/authn/authn_utils.cc @@ -15,7 +15,7 @@ #include "authn_utils.h" #include "common/json/json_loader.h" -#include "src/envoy/http/jwt_auth/jwt.h" +#include "src/envoy/utils/jwt.h" namespace Envoy { namespace Http { @@ -61,7 +61,7 @@ bool AuthnUtils::GetJWTPayloadFromHeaders( } std::string value(entry->value().c_str(), entry->value().size());
