commit bed2324647cb49dbf7762014cf961fda6ab65733 Author: Richard Pospesel richard@torproject.org Date: Fri May 21 22:18:23 2021 +0200

Bug 40416: Add v2 Onion deprecation warnings

- adds new v2 deprecated warning page (js and styling) that piggy-backs off of the existing added onion service errors - updates identity-icon to onionWarning.svg when visiting a v2 onion site adds warning tooltip; this warning supersedes all other identity states (including mixed-content error) - we determine whether to show the warning page in nsDocShell::DoURILoad() - a new synchonous IPC method is added to ContentChild/ContentParent to determine if the session has loaded the warning page already; worst case scenario, each child process will need to wait on this method to return only once when visiting a v2 onion; nothing is permanently cached with regards to this change - an exception for the new sync method is added to sync-messages.ini (generally, in practice adding new blocking methods is probably bad, but the minimial overhead and frequency this method is called is worth the simpler code) --- browser/base/content/aboutNetError.xhtml | 3 ++ browser/base/content/browser-siteIdentity.js | 12 +++++ browser/base/jar.mn | 2 +- .../content/netError/onionNetError.js | 6 +++ .../content/netError/v2Deprecated.css | 25 +++++++++ .../onionservices/content/netError/v2Deprecated.js | 50 ++++++++++++++++++ browser/components/onionservices/jar.mn | 8 ++- browser/modules/TorStrings.jsm | 8 +++ .../shared/identity-block/identity-block.inc.css | 3 +- browser/themes/shared/onionPattern.inc.xhtml | 4 +- docshell/base/nsDocShell.cpp | 61 ++++++++++++++++++++++ dom/ipc/ContentParent.cpp | 11 ++++ dom/ipc/ContentParent.h | 2 + dom/ipc/PContent.ipdl | 3 ++ ipc/ipdl/sync-messages.ini | 3 ++ js/xpconnect/src/xpc.msg | 1 + xpcom/base/ErrorList.py | 2 + 17 files changed, 200 insertions(+), 4 deletions(-)
