commit b063609e67cf00d426e320a55a03f901385f96ab Author: Kathy Brade <brade(a)pearlcrescent.com> Date: Tue Apr 29 13:08:24 2014 -0400 Bug 11641: change TBB directory structure to be more like Firefox's Unless the -osint command line flag is used, the browser now defaults to the equivalent of -no-remote.

[tor-browser/tor-browser-87.0b4-10.5-1] Bug 18821: Disable libmdns for Android and Desktop
by sysrqb＠torproject.org 11 Mar '21

11 Mar '21

commit cd9f9f610d7174ba010333811cbac765bf973d13 Author: Georg Koppen <gk(a)torproject.org> Date: Wed Apr 20 14:34:50 2016 +0000 Bug 18821: Disable libmdns for Android and Desktop There should be no need to remove the OS X support introduced in https://bugzilla.mozilla.org/show_bug.cgi?id=1225726 as enabling this is governed by a preference (which is actually set to `false`). However, we remove it at build time as well (defense in depth). This is basically a backout of the relevant passages of https://hg.mozilla.org/mozilla-central/rev/6bfb430de85d, https://hg.mozilla.org/mozilla-central/rev/609b337bf7ab and https://hg.mozilla.org/mozilla-central/rev/8e092ec5fbbd. Fixed bug 21861 (Disable additional mDNS code to avoid proxy bypasses) as well. --- dom/presentation/provider/components.conf | 10 ---------- dom/presentation/provider/moz.build | 1 - netwerk/dns/mdns/libmdns/components.conf | 15 --------------- netwerk/dns/mdns/libmdns/moz.build | 28 ---------------------------- 4 files changed, 54 deletions(-) diff --git a/dom/presentation/provider/components.conf b/dom/presentation/provider/components.conf index 04cb28ec757e..56994ed7cd94 100644 --- a/dom/presentation/provider/components.conf +++ b/dom/presentation/provider/components.conf @@ -6,9 +6,6 @@ categories = {} -if buildconfig.substs['MOZ_WIDGET_TOOLKIT'] in ('cocoa', 'android'): - categories["presentation-device-provider"] = "MulticastDNSDeviceProvider" - Classes = [ { 'cid': '{f4079b8b-ede5-4b90-a112-5b415a931deb}', @@ -16,11 +13,4 @@ Classes = [ 'jsm': 'resource://gre/modules/PresentationControlService.jsm', 'constructor': 'PresentationControlService', }, - { - 'cid': '{814f947a-52f7-41c9-94a1-3684797284ac}', - 'contract_ids': ['@mozilla.org/presentation-device/multicastdns-provider;1'], - 'type': 'mozilla::dom::presentation::MulticastDNSDeviceProvider', - 'headers': ['/dom/presentation/provider/MulticastDNSDeviceProvider.h'], - 'categories': categories, - }, ] diff --git a/dom/presentation/provider/moz.build b/dom/presentation/provider/moz.build index f6c4527d2cdf..9fab92997787 100644 --- a/dom/presentation/provider/moz.build +++ b/dom/presentation/provider/moz.build @@ -8,7 +8,6 @@ EXTRA_JS_MODULES += ["PresentationControlService.jsm"] UNIFIED_SOURCES += [ "DeviceProviderHelpers.cpp", - "MulticastDNSDeviceProvider.cpp", ] XPCOM_MANIFESTS += [ diff --git a/netwerk/dns/mdns/libmdns/components.conf b/netwerk/dns/mdns/libmdns/components.conf index 6e64140c820e..1b50dbf673a4 100644 --- a/netwerk/dns/mdns/libmdns/components.conf +++ b/netwerk/dns/mdns/libmdns/components.conf @@ -5,20 +5,5 @@ # file, You can obtain one at http://mozilla.org/MPL/2.0/.

[tor-browser/tor-browser-87.0b4-10.5-1] Bug 19273: Avoid JavaScript patching of the external app helper dialog.

commit 49cea828cc49c1f6daa9604848bd1a9a1f425a86 Author: Kathy Brade <brade(a)pearlcrescent.com> Date: Tue Jun 28 15:13:05 2016 -0400 Bug 19273: Avoid JavaScript patching of the external app helper dialog. When handling an external URI or downloading a file, invoke Torbutton's external app blocker component (which will present a download warning dialog unless the user has checked the "Automatically download files from now on" box). For e10s compatibility, avoid using a modal dialog and instead use a callback interface (nsIHelperAppWarningLauncher) to allow Torbutton to indicate the user's desire to cancel or continue each request. Other bugs fixed: Bug 21766: Crash with e10s enabled while trying to download a file Bug 21886: Download is stalled in non-e10s mode Bug 22471: Downloading files via the PDF viewer download button is broken Bug 22472: Fix FTP downloads when external helper app dialog is shown Bug 22610: Avoid crashes when canceling external helper app downloads Bug 22618: Downloading pdf file via file:/// is stalling --- .../exthandler/nsExternalHelperAppService.cpp | 172 ++++++++++++++++++--- uriloader/exthandler/nsExternalHelperAppService.h | 3 + .../exthandler/nsIExternalHelperAppService.idl | 47 ++++++ 3 files changed, 204 insertions(+), 18 deletions(-) diff --git a/uriloader/exthandler/nsExternalHelperAppService.cpp b/uriloader/exthandler/nsExternalHelperAppService.cpp index 92927822d792..c02a03d27d2c 100644 --- a/uriloader/exthandler/nsExternalHelperAppService.cpp +++ b/uriloader/exthandler/nsExternalHelperAppService.cpp @@ -133,6 +133,9 @@ static const char NEVER_ASK_FOR_SAVE_TO_DISK_PREF[] = static const char NEVER_ASK_FOR_OPEN_FILE_PREF[] = "browser.helperApps.neverAsk.openFile";

[tor-browser/tor-browser-87.0b4-10.5-1] Bug 13379: Sign our MAR files.
by sysrqb＠torproject.org 11 Mar '21

11 Mar '21

commit b32667fe79455bbbe6d4f6970800ababc1359714 Author: Kathy Brade <brade(a)pearlcrescent.com> Date: Wed Dec 17 16:37:11 2014 -0500 Bug 13379: Sign our MAR files. Configure with --enable-verify-mar (when updating, require a valid signature on the MAR file before it is applied). Use the Tor Browser version instead of the Firefox version inside the MAR file info block (necessary to prevent downgrade attacks). Use NSS on all platforms for checking MAR signatures (instead of using OS-native APIs, which Mozilla does on Mac OS and Windows). So that the NSS and NSPR libraries the updater depends on can be found at runtime, we add the firefox directory to the shared library search path on macOS. On Linux, rpath is used by Mozilla to solve that problem, but that approach won't work on macOS because the updater executable is copied during the update process to a location that is under TorBrowser-Data, and the location of TorBrowser-Data varies. Also includes the fix for bug 18900. --- .mozconfig | 1 + .mozconfig-asan | 1 + .mozconfig-mac | 1 + .mozconfig-mingw | 1 + modules/libmar/tool/mar.c | 6 +-- modules/libmar/tool/moz.build | 12 ++++-- modules/libmar/verify/moz.build | 14 +++--- .../mozapps/update/updater/updater-common.build | 26 +++++++++-- toolkit/mozapps/update/updater/updater.cpp | 25 +++++++---- toolkit/xre/moz.build | 3 ++ toolkit/xre/nsUpdateDriver.cpp | 50 ++++++++++++++++++++++ 11 files changed, 115 insertions(+), 25 deletions(-) diff --git a/.mozconfig b/.mozconfig index 18cd1f9b6487..c50c57d410de 100755 --- a/.mozconfig +++ b/.mozconfig @@ -37,3 +37,4 @@ ac_add_options MOZ_TELEMETRY_REPORTING= ac_add_options --disable-tor-launcher ac_add_options --with-tor-browser-version=dev-build ac_add_options --disable-tor-browser-update +ac_add_options --enable-verify-mar diff --git a/.mozconfig-asan b/.mozconfig-asan index bad7ea022c9f..e42ff6c86bc5 100644 --- a/.mozconfig-asan +++ b/.mozconfig-asan @@ -29,6 +29,7 @@ ac_add_options --enable-official-branding ac_add_options --enable-default-toolkit=cairo-gtk3 ac_add_options --enable-tor-browser-update +ac_add_options --enable-verify-mar ac_add_options --disable-strip ac_add_options --disable-install-strip diff --git a/.mozconfig-mac b/.mozconfig-mac index 26e2b6b92fdb..5b4624ef1f67 100644 --- a/.mozconfig-mac +++ b/.mozconfig-mac @@ -43,6 +43,7 @@ ac_add_options --disable-debug ac_add_options --enable-tor-browser-data-outside-app-dir ac_add_options --enable-tor-browser-update +ac_add_options --enable-verify-mar ac_add_options --disable-crashreporter ac_add_options --disable-webrtc diff --git a/.mozconfig-mingw b/.mozconfig-mingw index 3ec6ff18a3e9..ce6ace1dad67 100644 --- a/.mozconfig-mingw +++ b/.mozconfig-mingw @@ -15,6 +15,7 @@ ac_add_options --enable-strip ac_add_options --enable-official-branding ac_add_options --enable-tor-browser-update +ac_add_options --enable-verify-mar ac_add_options --disable-bits-download # Let's make sure no preference is enabling either Adobe's or Google's CDM. diff --git a/modules/libmar/tool/mar.c b/modules/libmar/tool/mar.c index 0bf2cb4bd1d4..ea2b79924914 100644 --- a/modules/libmar/tool/mar.c +++ b/modules/libmar/tool/mar.c @@ -65,7 +65,7 @@ static void print_usage() { "signed_input_archive.mar base_64_encoded_signature_file " "changed_signed_output.mar\n");

by sysrqb＠torproject.org 11 Mar '21

commit 8f664c9dacaf388564b47af52e5430f1ca1dce7e Author: Igor Oliveira <igor.oliveira(a)posteo.net> Date: Sun Dec 10 18:16:59 2017 -0200 Bug 23104: Add a default line height compensation Many fonts have issues with their vertical metrics. they are used to influence the height of ascenders and depth of descenders. Gecko uses it to calculate the line height (font height + ascender + descender), however because of that idiosyncratic behavior across multiple operating systems, it can be used to identify the user's OS. The solution proposed in the patch uses a default factor to be multiplied with the font size, simulating the concept of ascender and descender. This way all operating systems will have the same line height only and only if the frame is outside the chrome. --- layout/generic/ReflowInput.cpp | 19 +++++++++--- layout/generic/test/mochitest.ini | 1 + layout/generic/test/test_tor_bug23104.html | 50 ++++++++++++++++++++++++++++++ 3 files changed, 65 insertions(+), 5 deletions(-) diff --git a/layout/generic/ReflowInput.cpp b/layout/generic/ReflowInput.cpp index b9584a8b405b..03b5f4db0f0a 100644 --- a/layout/generic/ReflowInput.cpp +++ b/layout/generic/ReflowInput.cpp @@ -31,6 +31,7 @@ #include "mozilla/SVGUtils.h" #include "mozilla/dom/HTMLInputElement.h" #include "nsGridContainerFrame.h" +#include "nsContentUtils.h" using namespace mozilla; using namespace mozilla::css; @@ -2633,7 +2634,8 @@ void ReflowInput::CalculateBlockSideMargins() { // For risk management, we use preference to control the behavior, and // eNoExternalLeading is the old behavior. -static nscoord GetNormalLineHeight(nsFontMetrics* aFontMetrics) { +static nscoord GetNormalLineHeight(nsIContent* aContent, + nsFontMetrics* aFontMetrics) { MOZ_ASSERT(nullptr != aFontMetrics, "no font metrics"); nscoord normalLineHeight; @@ -2641,6 +2643,12 @@ static nscoord GetNormalLineHeight(nsFontMetrics* aFontMetrics) { nscoord externalLeading = aFontMetrics->ExternalLeading(); nscoord internalLeading = aFontMetrics->InternalLeading(); nscoord emHeight = aFontMetrics->EmHeight(); + + if (nsContentUtils::ShouldResistFingerprinting() && + !aContent->IsInChromeDocument()) { + return NSToCoordRound(emHeight * NORMAL_LINE_HEIGHT_FACTOR); + } + switch (GetNormalLineHeightCalcControl()) { case eIncludeExternalLeading: normalLineHeight = emHeight + internalLeading + externalLeading; @@ -2658,7 +2666,8 @@ static nscoord GetNormalLineHeight(nsFontMetrics* aFontMetrics) { return normalLineHeight; } -static inline nscoord ComputeLineHeight(ComputedStyle* aComputedStyle, +static inline nscoord ComputeLineHeight(nsIContent* aContent, + ComputedStyle* aComputedStyle, nsPresContext* aPresContext, nscoord aBlockBSize, float aFontSizeInflation) { @@ -2687,7 +2696,7 @@ static inline nscoord ComputeLineHeight(ComputedStyle* aComputedStyle, RefPtr<nsFontMetrics> fm = nsLayoutUtils::GetFontMetricsForComputedStyle( aComputedStyle, aPresContext, aFontSizeInflation); - return GetNormalLineHeight(fm); + return GetNormalLineHeight(aContent, fm); } nscoord ReflowInput::CalcLineHeight() const { @@ -2709,7 +2718,7 @@ nscoord ReflowInput::CalcLineHeight(nsIContent* aContent, float aFontSizeInflation) { MOZ_ASSERT(aComputedStyle, "Must have a ComputedStyle"); - nscoord lineHeight = ComputeLineHeight(aComputedStyle, aPresContext, + nscoord lineHeight = ComputeLineHeight(aContent, aComputedStyle, aPresContext, aBlockBSize, aFontSizeInflation); NS_ASSERTION(lineHeight >= 0, "ComputeLineHeight screwed up"); @@ -2722,7 +2731,7 @@ nscoord ReflowInput::CalcLineHeight(nsIContent* aContent, if (!lh.IsNormal()) { RefPtr<nsFontMetrics> fm = nsLayoutUtils::GetFontMetricsForComputedStyle( aComputedStyle, aPresContext, aFontSizeInflation); - nscoord normal = GetNormalLineHeight(fm); + nscoord normal = GetNormalLineHeight(aContent, fm); if (lineHeight < normal) { lineHeight = normal; } diff --git a/layout/generic/test/mochitest.ini b/layout/generic/test/mochitest.ini index 072b11da7eb6..3c377e0781ed 100644 --- a/layout/generic/test/mochitest.ini +++ b/layout/generic/test/mochitest.ini @@ -145,3 +145,4 @@ skip-if = debug == true || tsan # the test is slow. tsan: bug 1612707 support-files = file_reframe_for_lazy_load_image.html [test_bug1655135.html] +[test_tor_bug23104.html] diff --git a/layout/generic/test/test_tor_bug23104.html b/layout/generic/test/test_tor_bug23104.html new file mode 100644 index 000000000000..8ff1d2190c45 --- /dev/null +++ b/layout/generic/test/test_tor_bug23104.html @@ -0,0 +1,50 @@ +<!DOCTYPE HTML> +<meta charset="UTF-8"> +<html> +<head> + <title>Test for Tor Bug #23104: CSS line-height reveals the platform Tor browser is running</title> + <script type="application/javascript" src="/tests/SimpleTest/SimpleTest.js"></script> + <script type="application/javascript" src="/tests/SimpleTest/SpawnTask.js"></script> + <style type="text/css"> + span { + background-color: #000; + color: #fff; + font-size: 16.5px; + } + </style> +</head> +<body> +<span id="test1">Test1</span> +<span id="test2">كلمة</span> +<span id="test3">ação</span> +<script> + +let setPref = async function (key, value) { + await SpecialPowers.pushPrefEnv({"set": [[key, value]]}); +} + +function getStyle(el, styleprop) { + el = document.getElementById(el); + return document.defaultView.getComputedStyle(el, null).getPropertyValue(styleprop); +} + +function validateElement(elementName, isFingerprintResistent) { + var fontSize = getStyle(elementName, 'font-size'); + var lineHeight = getStyle(elementName, 'line-height'); + var validationCb = isFingerprintResistent ?

[tor-browser/tor-browser-87.0b4-10.5-1] Bug 19121: reinstate the update.xml hash check

commit f3c340a62dc8c892bb7f9d7dc9c4359929fafd76 Author: Kathy Brade <brade(a)pearlcrescent.com> Date: Mon Apr 23 15:22:57 2018 -0400 Bug 19121: reinstate the update.xml hash check Revert most changes from Mozilla Bug 1373267 "Remove hashFunction and hashValue attributes from nsIUpdatePatch and code related to these attributes." Changes to the tests were not reverted; the tests have been changed significantly and we do not run automated updater tests for Tor Browser at this time. Also partial revert of commit f1241db6986e4b54473a1ed870f7584c75d51122. Revert the nsUpdateService.js changes from Mozilla Bug 862173 "don't verify mar file hash when using mar signing to verify the mar file (lessens main thread I/O)." Changes to the tests were not reverted; the tests have been changed significantly and we do not run automated updater tests for Tor Browser at this time. We kept the addition to the AppConstants API in case other JS code references it in the future. --- toolkit/modules/AppConstants.jsm | 7 ++++ toolkit/mozapps/update/UpdateService.jsm | 63 ++++++++++++++++++++++++++++- toolkit/mozapps/update/UpdateTelemetry.jsm | 1 + toolkit/mozapps/update/nsIUpdateService.idl | 11 +++++ 4 files changed, 81 insertions(+), 1 deletion(-) diff --git a/toolkit/modules/AppConstants.jsm b/toolkit/modules/AppConstants.jsm index dc71230b77fb..79fbb9303cf6 100644 --- a/toolkit/modules/AppConstants.jsm +++ b/toolkit/modules/AppConstants.jsm @@ -212,6 +212,13 @@ this.AppConstants = Object.freeze({ false, #endif + MOZ_VERIFY_MAR_SIGNATURE: +#ifdef MOZ_VERIFY_MAR_SIGNATURE + true, +#else + false, +#endif + MOZ_MAINTENANCE_SERVICE: #ifdef MOZ_MAINTENANCE_SERVICE true, diff --git a/toolkit/mozapps/update/UpdateService.jsm b/toolkit/mozapps/update/UpdateService.jsm index e615f7d6fdc0..6298ef2e3fe0 100644 --- a/toolkit/mozapps/update/UpdateService.jsm +++ b/toolkit/mozapps/update/UpdateService.jsm @@ -907,6 +907,20 @@ function LOG(string) { } } +/** + * Convert a string containing binary values to hex. + */ +function binaryToHex(input) { + var result = ""; + for (var i = 0; i < input.length; ++i) { + var hex = input.charCodeAt(i).toString(16); + if (hex.length == 1) + hex = "0" + hex; + result += hex; + } + return result; +} + /** * Gets the specified directory at the specified hierarchy under the * update root directory and creates it if it doesn't exist. @@ -1907,6 +1921,8 @@ function UpdatePatch(patch) { } break; case "finalURL": + case "hashFunction": + case "hashValue": case "state": case "type": case "URL": @@ -1926,6 +1942,8 @@ UpdatePatch.prototype = { // over writing nsIUpdatePatch attributes. _attrNames: [ "errorCode", + "hashFunction", + "hashValue", "finalURL", "selected", "size", @@ -1939,6 +1957,8 @@ UpdatePatch.prototype = { */ serialize: function UpdatePatch_serialize(updates) { var patch = updates.createElementNS(URI_UPDATE_NS, "patch"); + patch.setAttribute("hashFunction", this.hashFunction); + patch.setAttribute("hashValue", this.hashValue); patch.setAttribute("size", this.size); patch.setAttribute("type", this.type); patch.setAttribute("URL", this.URL); @@ -4962,7 +4982,42 @@ Downloader.prototype = { } LOG("Downloader:_verifyDownload downloaded size == expected size."); - return true; + let fileStream = Cc["@mozilla.org/network/file-input-stream;1"]. + createInstance(Ci.nsIFileInputStream); + fileStream.init(destination, FileUtils.MODE_RDONLY, FileUtils.PERMS_FILE, 0); + + let digest; + try { + let hash = Cc["@mozilla.org/security/hash;1"]. + createInstance(Ci.nsICryptoHash); + var hashFunction = Ci.nsICryptoHash[this._patch.hashFunction.toUpperCase()]; + if (hashFunction == undefined) { + throw Cr.NS_ERROR_UNEXPECTED; + } + hash.init(hashFunction); + hash.updateFromStream(fileStream, -1); + // NOTE: For now, we assume that the format of _patch.hashValue is hex + // encoded binary (such as what is typically output by programs like + // sha1sum).
