From ea456fc2bf09e1b80a3add3b898175605da3bf60 Mon Sep 17 00:00:00 2001 From: Julien Boeuf Date: Tue, 7 Jul 2015 15:23:30 -0700 Subject: [PATCH 1/2] Server auth metadata processor. - Right now it is a global function: would be better to have this per (secure) port. - Changed the interface of the auth_context slightly to make it more friendly. - Positive tests pass. Still need some work on error case (have a negative case as well). - Fixing cpp auth context tests so that they use the shiny new C API. --- include/grpc/grpc_security.h | 46 ++- src/core/security/credentials.c | 48 +-- src/core/security/credentials.h | 13 +- src/core/security/security_connector.c | 32 +- src/core/security/security_context.c | 101 ++++-- src/core/security/security_context.h | 34 +- src/core/security/server_auth_filter.c | 166 ++++++++- src/core/transport/stream_op.h | 2 +- .../chttp2_simple_ssl_with_oauth2_fullstack.c | 4 +- ...est_response_with_payload_and_call_creds.c | 322 +++++++++++++++++- test/core/security/auth_context_test.c | 73 ++-- test/core/security/credentials_test.c | 8 +- .../cpp/common/auth_property_iterator_test.cc | 15 +- test/cpp/common/secure_auth_context_test.cc | 22 +- 14 files changed, 715 insertions(+), 171 deletions(-) diff --git a/include/grpc/grpc_security.h b/include/grpc/grpc_security.h index 37d66c04ae5..9e193e697f8 100644 --- a/include/grpc/grpc_security.h +++ b/include/grpc/grpc_security.h @@ -203,8 +203,6 @@ grpc_call_error grpc_call_set_credentials(grpc_call *call, /* --- Authentication Context. --- */ -/* TODO(jboeuf): Define some well-known property names. */ - #define GRPC_TRANSPORT_SECURITY_TYPE_PROPERTY_NAME "transport_security_type" #define GRPC_FAKE_TRANSPORT_SECURITY_TYPE "fake" #define GRPC_SSL_TRANSPORT_SECURITY_TYPE "ssl" @@ -260,6 +258,50 @@ grpc_auth_context *grpc_call_auth_context(grpc_call *call); /* Releases the auth context returned from grpc_call_auth_context. */ void grpc_auth_context_release(grpc_auth_context *context); +/* -- + The following auth context methods should only be called by a server metadata + processor that will augment the channel auth context (see below). + -- */ + +/* Creates a new auth context based off a chained context. */ +grpc_auth_context *grpc_auth_context_create(grpc_auth_context *chained); + +/* Add a property. */ +void grpc_auth_context_add_property(grpc_auth_context *ctx, const char *name, + const char *value, size_t value_length); + +/* Add a C string property. */ +void grpc_auth_context_add_cstring_property(grpc_auth_context *ctx, + const char *name, + const char *value); + +/* Sets the property name.
