commit 1e2826d96f36d46a0060afc2ae1a279c923dc3a2 Author: Mike Perry <mikeperry-git(a)torproject.org> Date: Mon Sep 29 14:30:19 2014 -0700 Bug 13028: Prevent potential proxy bypass cases. It looks like these cases should only be invoked in the NSS command line tools, and not the browser, but I decided to patch them anyway because there literally is a maze of network function pointers being passed around, and it's very hard to tell if some random code might not pass in the proper proxied versions of the networking code here by accident. --- security/nss/lib/certhigh/ocsp.c | 8 ++++++++ .../lib/libpkix/pkix_pl_nss/module/pkix_pl_socket.c | 21 +++++++++++++++++++++ 2 files changed, 29 insertions(+) diff --git a/security/nss/lib/certhigh/ocsp.c b/security/nss/lib/certhigh/ocsp.c index cea8456606bf..86fa971cfbef 100644 --- a/security/nss/lib/certhigh/ocsp.c +++ b/security/nss/lib/certhigh/ocsp.c @@ -2932,6 +2932,14 @@ ocsp_ConnectToHost(const char *host, PRUint16 port) PRNetAddr addr; char *netdbbuf = NULL; + // XXX: Do we need a unittest ifdef here?

[tor-browser/tor-browser-84.0-10.0-1] Bug 13252: Do not store data in the app bundle
by sysrqb＠torproject.org 11 Dec '20

commit f909b8b97bcb8b0df4672cb9b366787a8e291db5 Author: Kathy Brade <brade(a)pearlcrescent.com> Date: Fri Mar 18 14:20:02 2016 -0400 Bug 13252: Do not store data in the app bundle When --enable-tor-browser-data-outside-app-dir is enabled, all user data is stored in a directory named TorBrowser-Data which is located next to the application directory. Display an informative error message if the TorBrowser-Data directory cannot be created due to an "access denied" or a "read only volume" error. On Mac OS, add support for the --invisible command line option which is used by the meek-http-helper to avoid showing an icon for the helper browser on the dock. --- toolkit/xre/nsAppRunner.cpp | 76 +++++++++++++++---- toolkit/xre/nsXREDirProvider.cpp | 43 +++++------ toolkit/xre/nsXREDirProvider.h | 6 ++ xpcom/io/TorFileUtils.cpp | 133 +++++++++++++++++++++++++++++++++ xpcom/io/TorFileUtils.h | 32 ++++++++ xpcom/io/moz.build | 5 ++ xpcom/io/nsAppFileLocationProvider.cpp | 53 ++++++------- 7 files changed, 280 insertions(+), 68 deletions(-) diff --git a/toolkit/xre/nsAppRunner.cpp b/toolkit/xre/nsAppRunner.cpp index 21c5415a5dff..51a1a43ec891 100644 --- a/toolkit/xre/nsAppRunner.cpp +++ b/toolkit/xre/nsAppRunner.cpp @@ -2369,6 +2369,8 @@ static nsresult ProfileMissingDialog(nsINativeAppSupport* aNative) { } } +// If aUnlocker is NULL, it is also OK for the following arguments to be NULL: +// aProfileDir, aProfileLocalDir, aResult. static ReturnAbortOnError ProfileErrorDialog(nsIFile* aProfileDir, nsIFile* aProfileLocalDir, ProfileStatus aStatus, @@ -2377,17 +2379,19 @@ static ReturnAbortOnError ProfileErrorDialog(nsIFile* aProfileDir, nsIProfileLock** aResult) { nsresult rv; - bool exists; - aProfileDir->Exists(&exists); - if (!exists) { - return ProfileMissingDialog(aNative); + if (aProfileDir) { + bool exists; + aProfileDir->Exists(&exists); + if (!exists) { + return ProfileMissingDialog(aNative); + } } ScopedXPCOMStartup xpcom; rv = xpcom.Initialize(); NS_ENSURE_SUCCESS(rv, rv); - mozilla::Telemetry::WriteFailedProfileLock(aProfileDir); + if (aProfileDir) mozilla::Telemetry::WriteFailedProfileLock(aProfileDir); rv = xpcom.SetWindowCreator(aNative); NS_ENSURE_SUCCESS(rv, NS_ERROR_FAILURE); @@ -2477,7 +2481,8 @@ static ReturnAbortOnError ProfileErrorDialog(nsIFile* aProfileDir, } } else { #ifdef MOZ_WIDGET_ANDROID - if (java::GeckoAppShell::UnlockProfile()) { + if (aProfileDir && aProfileLocalDir && aResult && + java::GeckoAppShell::UnlockProfile()) { return NS_LockProfilePath(aProfileDir, aProfileLocalDir, nullptr, aResult); } @@ -2586,6 +2591,23 @@ static ReturnAbortOnError ShowProfileManager( return LaunchChild(false); } +#ifdef TOR_BROWSER_DATA_OUTSIDE_APP_DIR +static ProfileStatus CheckTorBrowserDataWriteAccess(nsIFile* aAppDir) { + // Check whether we can write to the directory that will contain + // TorBrowser-Data. + nsCOMPtr<nsIFile> tbDataDir; + RefPtr<nsXREDirProvider> dirProvider = nsXREDirProvider::GetSingleton(); + if (!dirProvider) return PROFILE_STATUS_OTHER_ERROR; + nsresult rv = + dirProvider->GetTorBrowserUserDataDir(getter_AddRefs(tbDataDir)); + NS_ENSURE_SUCCESS(rv, PROFILE_STATUS_OTHER_ERROR); + nsCOMPtr<nsIFile> tbDataDirParent; + rv = tbDataDir->GetParent(getter_AddRefs(tbDataDirParent)); + NS_ENSURE_SUCCESS(rv, PROFILE_STATUS_OTHER_ERROR); + return nsToolkitProfileService::CheckProfileWriteAccess(tbDataDirParent); +} +#endif + static bool gDoMigration = false; static bool gDoProfileReset = false; static nsCOMPtr<nsIToolkitProfile> gResetOldProfile; @@ -3610,6 +3632,14 @@ int XREMain::XRE_mainInit(bool* aExitFlag) { if (PR_GetEnv("XRE_MAIN_BREAK")) NS_BREAK(); #endif +#if defined(XP_MACOSX) && defined(TOR_BROWSER_DATA_OUTSIDE_APP_DIR) + bool hideDockIcon = (CheckArg("invisible") == ARG_FOUND); + if (hideDockIcon) { + ProcessSerialNumber psn = {0, kCurrentProcess}; + TransformProcessType(&psn, kProcessTransformToBackgroundApplication); + } +#endif + IncreaseDescriptorLimits(); #ifdef USE_GLX_TEST @@ -4458,7 +4488,34 @@ int XREMain::XRE_mainStartup(bool* aExitFlag) { return 0; } +#if (defined(MOZ_UPDATER) && !defined(MOZ_WIDGET_ANDROID)) || \ + defined(TOR_BROWSER_DATA_OUTSIDE_APP_DIR) + nsCOMPtr<nsIFile> exeFile, exeDir; + bool persistent; + rv = mDirProvider.GetFile(XRE_EXECUTABLE_FILE, &persistent, + getter_AddRefs(exeFile)); + NS_ENSURE_SUCCESS(rv, 1); + rv = exeFile->GetParent(getter_AddRefs(exeDir)); + NS_ENSURE_SUCCESS(rv, 1); +#endif + rv = NS_NewToolkitProfileService(getter_AddRefs(mProfileSvc)); +#ifdef TOR_BROWSER_DATA_OUTSIDE_APP_DIR + if (NS_FAILED(rv)) { + // NS_NewToolkitProfileService() returns a generic NS_ERROR_FAILURE error + // if creation of the TorBrowser-Data directory fails due to access denied + // or because of a read-only disk volume.

[tor-browser/tor-browser-84.0-10.0-1] Bug 18821: Disable libmdns for Android and Desktop
by sysrqb＠torproject.org 11 Dec '20

11 Dec '20

commit c4037a4bc377fa7e3212cc281697f7978cce1873 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`).

[tor-browser/tor-browser-84.0-10.0-1] Bug 19121: reinstate the update.xml hash check
by sysrqb＠torproject.org 11 Dec '20

commit 610b39377edb9af740a4f1020f725669509f17ae 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 f94c47cc8953..e42c8ed8d0b9 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 9f5e88efc5e6..6756fad9ce05 100644 --- a/toolkit/mozapps/update/UpdateService.jsm +++ b/toolkit/mozapps/update/UpdateService.jsm @@ -799,6 +799,20 @@ 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. @@ -1612,6 +1626,8 @@ function UpdatePatch(patch) { } break; case "finalURL": + case "hashFunction": + case "hashValue": case "state": case "type": case "URL": @@ -1631,6 +1647,8 @@ UpdatePatch.prototype = { // over writing nsIUpdatePatch attributes. _attrNames: [ "errorCode", + "hashFunction", + "hashValue", "finalURL", "selected", "size", @@ -1644,6 +1662,8 @@ 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); @@ -4480,7 +4500,42 @@ 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).

[tor-browser/tor-browser-84.0-10.0-1] Bug 19273: Avoid JavaScript patching of the external app helper dialog.

commit 1929918f708a8656eb632622e70ace6a864b1ab1 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 16b7be9b364a..8028eaeafaab 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";
