commit c24a667e4cae82bb8ca0c1c41b63dcddbc96eb27 Author: Pier Angelo Vendrame pierov@torproject.org AuthorDate: Mon Feb 21 15:39:11 2022 +0100
Bug 40458: Implement .tor.onion aliases
We have enabled HTTPS-Only mode, therefore we do not need HTTPS-Everywhere anymore. However, we want to keep supporting .tor.onion aliases (especially for securedrop). Therefore, in this patch we implemented the parsing of HTTPS-Everywhere rulesets, and the redirect of .tor.onion domains. Actually, Tor Browser believes they are actual domains. We change them on the fly on the SOCKS proxy requests to resolve the domain, and on the code that verifies HTTPS certificates. --- browser/components/BrowserGlue.jsm | 42 ++ browser/components/about/AboutRedirector.cpp | 5 + browser/components/about/components.conf | 1 + browser/components/moz.build | 1 + .../components/onionservices/OnionAliasStore.jsm | 563 +++++++++++++++++++++ browser/components/onionservices/moz.build | 1 + browser/components/rulesets/RulesetsChild.jsm | 11 + browser/components/rulesets/RulesetsParent.jsm | 79 +++ .../components/rulesets/content/aboutRulesets.css | 305 +++++++++++ .../components/rulesets/content/aboutRulesets.html | 107 ++++ .../components/rulesets/content/aboutRulesets.js | 531 +++++++++++++++++++ browser/components/rulesets/content/securedrop.svg | 173 +++++++ browser/components/rulesets/jar.mn | 5 + browser/components/rulesets/moz.build | 6 + modules/libpref/init/StaticPrefList.yaml | 5 + netwerk/build/components.conf | 11 + netwerk/build/nsNetCID.h | 10 + netwerk/dns/IOnionAliasService.idl | 34 ++ netwerk/dns/OnionAliasService.cpp | 99 ++++ netwerk/dns/OnionAliasService.h | 40 ++ netwerk/dns/effective_tld_names.dat | 2 + netwerk/dns/moz.build | 4 + netwerk/socket/nsSOCKSIOLayer.cpp | 24 +- security/manager/ssl/SSLServerCertVerification.cpp | 9 + security/manager/ssl/SSLServerCertVerification.h | 4 +- toolkit/modules/RemotePageAccessManager.jsm | 14 + 26 files changed, 2080 insertions(+), 6 deletions(-)
