From 1618b68bfa740ed655ac45d7d5f4f46fed6c8c62 Mon Sep 17 00:00:00 2001 From: Eugen Rochko Date: Fri, 14 Jul 2017 20:41:49 +0200 Subject: [PATCH] HTTP signatures (#4146) * Add Request class with HTTP signature generator Spec: https://tools.ietf.org/html/draft-cavage-http-signatures-06 * Add HTTP signature verification concern * Add test for SignatureVerification concern * Add basic test for Request class * Make PuSH subscribe/unsubscribe requests use new Request class Accidentally fix lease_seconds not being set and sent properly, and change the new minimum subscription duration to 1 day * Make all PuSH workers use new Request class * Make Salmon sender use new Request class * Make FetchLinkService use new Request class * Make FetchAtomService use the new Request class * Make Remotable use the new Request class * Make ResolveRemoteAccountService use the new Request class * Add more tests * Allow +-30 seconds window for signed request to remain valid * Disable time window validation for signed requests, restore 7 days as PuSH subscription duration (which was previous default due to a bug) --- app/controllers/accounts_controller.rb | 1 + .../api/subscriptions_controller.rb | 2 +- .../concerns/signature_verification.rb | 87 +++++++++++++++++++ app/controllers/stream_entries_controller.rb | 1 + app/helpers/http_helper.rb | 17 ---- app/lib/provider_discovery.rb | 4 +- app/lib/request.rb | 70 +++++++++++++++ app/models/account.rb | 2 +- app/models/concerns/remotable.rb | 3 +- app/models/subscription.rb | 4 +- app/services/fetch_atom_service.rb | 8 +- app/services/fetch_link_card_service.rb | 6 +- .../resolve_remote_account_service.rb | 3 +- app/services/send_interaction_service.rb | 14 ++- app/services/subscribe_service.rb | 48 +++++++--- app/services/unsubscribe_service.rb | 31 +++++-- .../pubsubhubbub/confirmation_worker.rb | 12 ++- app/workers/pubsubhubbub/delivery_worker.rb | 11 ++- .../concerns/signature_verification_spec.rb | 74 ++++++++++++++++ spec/helpers/http_helper_spec.rb | 13 --- spec/lib/request_spec.rb | 54 ++++++++++++ .../pubsubhubbub/confirmation_worker_spec.rb | 2 +- .../pubsubhubbub/delivery_worker_spec.rb | 2 +- 23 files changed, 379 insertions(+), 90 deletions(-) create mode 100644 app/controllers/concerns/signature_verification.rb delete mode 100644 app/helpers/http_helper.rb create mode 100644 app/lib/request.rb create mode 100644 spec/controllers/concerns/signature_verification_spec.rb delete mode 100644 spec/helpers/http_helper_spec.rb create mode 100644 spec/lib/request_spec.rb diff --git a/app/controllers/accounts_controller.rb b/app/controllers/accounts_controller.rb index 11402ab79..69b520df1 100644 --- a/app/controllers/accounts_controller.rb +++ b/app/controllers/accounts_controller.rb @@ -2,6 +2,7 @@ class AccountsController < ApplicationController include AccountControllerConcern + include SignatureVerification def show respond_to do |format| diff --git a/app/controllers/api/subscriptions_controller.rb b/app/controllers/api/subscriptions_controller.rb index d3ea98676..89007f3d6 100644 --- a/app/controllers/api/subscriptions_controller.rb +++ b/app/controllers/api/subscriptions_controller.rb @@ -42,7 +42,7 @@ class Api::SubscriptionsController < Api::BaseController end def lease_seconds_or_default - (params['hub.lease_seconds'] || 86_400).to_i.seconds + (params['hub.lease_seconds'] || 1.day).to_i.seconds end def set_account diff --git a/app/controllers/concerns/signature_verification.rb b/app/controllers/concerns/signature_verification.rb new file mode 100644 index 000000000..abe845d93 --- /dev/null +++ b/app/controllers/concerns/signature_verification.rb @@ -0,0 +1,87 @@ +# frozen_string_literal: true + +# Implemented according to HTTP signatures (Draft 6) +# +module SignatureVerification + extend ActiveSupport::Concern + + def signed_request?
