commit 5d784358fcdbfad980b737824ed1565b237cc148 Author: Yawning Angel <yawning(a)schwanenlied.me> Date: Wed Apr 12 18:33:01 2017 +0000 Bug 21929: Remove hardened/ASAN related code. The removes the bulk of the `hardened`/ASAN related code, as it is no longer relevant. The tor-sans-obfs4 seccomp rules probably can tighten the permitted mmap arguments a bit, but that can wait till I have more time. --- ChangeLog | 1 + data/tor-common-amd64.seccomp | 4 --- data/torbrowser-amd64.seccomp | 4 --- .../internal/sandbox/application.go | 35 ++++++++-------------- .../internal/sandbox/hugbox.go | 2 +- .../internal/ui/config/config.go | 3 +- .../sandboxed-tor-browser/internal/ui/launch.go | 5 ---- src/cmd/sandboxed-tor-browser/internal/ui/ui.go | 18 +---------- 8 files changed, 17 insertions(+), 55 deletions(-) diff --git a/ChangeLog b/ChangeLog index 20cae09..e623392 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,4 +1,5 @@ Changes in version 0.0.4 - UNRELEASED: + * Bug 21929: Remove hardened/ASAN related code. * Bug 21927: Remove the ability to install/update the hardened bundle. * Bug 21244: Update the MAR signing key for 7.0. * Bug 21536: Remove asn's scramblesuit bridge from Tor Browser. diff --git a/data/tor-common-amd64.seccomp b/data/tor-common-amd64.seccomp index 5bc0428..c324843 100644 --- a/data/tor-common-amd64.seccomp +++ b/data/tor-common-amd64.seccomp @@ -96,10 +96,6 @@ unshare: 1 rt_sigaction: 1 setsid: 1 -# XXX: This is only required for ASAN builds, so this should be included at -# runtime. -readlink: 1 - # # System calls allowed with filtering. # diff --git a/data/torbrowser-amd64.seccomp b/data/torbrowser-amd64.seccomp index a2c2817..11e42e5 100644 --- a/data/torbrowser-amd64.seccomp +++ b/data/torbrowser-amd64.seccomp @@ -181,10 +181,6 @@ uname: 1 unshare: 1 wait4: 1 -# XXX: This is only required for ASAN builds, so this should be included at -# runtime. -setrlimit: 1 - # # System calls allowed with filtering. # diff --git a/src/cmd/sandboxed-tor-browser/internal/sandbox/application.go b/src/cmd/sandboxed-tor-browser/internal/sandbox/application.go index fa773d4..427c3b1 100644 --- a/src/cmd/sandboxed-tor-browser/internal/sandbox/application.go +++ b/src/cmd/sandboxed-tor-browser/internal/sandbox/application.go @@ -139,10 +139,16 @@ func RunTorBrowser(cfg *config.Config, manif *config.Manifest, tor *tor.Tor) (pr // h.setenv("LD_LIBRARY_PATH", filepath.Join(browserHome, "TorBrowser", "Tor")) h.setenv("FONTCONFIG_PATH", filepath.Join(browserHome, "TorBrowser", "Data", "fontconfig")) h.setenv("FONTCONFIG_FILE", "fonts.conf") - if manif.Channel == "hardened" { - h.setenv("ASAN_OPTIONS", "detect_leaks=0") - h.setenv("NSS_DISABLE_HW_AES", "1") // For selfrando. - } + + // This used to be for `hardened` but may eventually be required for + // `alpha`, though according to trac, newer versions of selfrando fix the + // problem. + // + // https://trac.torproject.org/projects/tor/ticket/20683#comment:13 + // + // if manif.Channel == "alpha" { + // h.setenv("NSS_DISABLE_HW_AES", "1") // For selfrando. + // } // GNOME systems will puke with a read-only home, so instead of setting // $HOME to point to inside the browser bundle, setup a bunch of @@ -176,19 +182,6 @@ func RunTorBrowser(cfg *config.Config, manif *config.Manifest, tor *tor.Tor) (pr h.assetFile(stubPath, "tbb_stub.so") ldPreload := stubPath - if manif.Channel == "hardened" { - // ASAN wants to be the first entry on LD_PRELOAD, so placate it. - matches, err := filepath.Glob(filepath.Join(realBrowserHome, "TorBrowser", "Tor") + "/libasan.so*") - if err != nil { - return nil, err - } - if len(matches) < 1 { - log.Printf("sandbox: Failed to find 'libasan.so.*'") - } else { - _, f := filepath.Split(matches[0]) - ldPreload = f + ":" + ldPreload - } - } h.setenv("LD_PRELOAD", ldPreload) // Hardware accelerated OpenGL will not work, and never will. @@ -520,13 +513,11 @@ func RunTor(cfg *config.Config, manif *config.Manifest, torrc []byte) (process * // `/proc/sys/net/core/somaxconn` - obfs4proxy, Go runtime uses this to // determine listener backlog, but will default to `128` on errors. // - // Hardened builds are special cased because asan crashes the binary - // if it can't read `/proc/self/maps`. + // `/proc/self/maps` - ASAN.

[sandboxed-tor-browser/master] Bug 21927: Remove the ability to install/update the hardened bundle.

commit dc0ca5edeea0c9e17b94444cd3d941502ac1d57f Author: Yawning Angel <yawning(a)schwanenlied.me> Date: Wed Apr 12 17:59:54 2017 +0000 Bug 21927: Remove the ability to install/update the hardened bundle. This removes the `hardened` bundle from install/update related metadata assets. New installs will no longer provide the user the option to install the `hardened` channel, and the update check will fail due to lack of an update URL. --- ChangeLog | 1 + data/installer/urls.json | 12 ++++-------- data/ui/channels.json | 2 +- data/ui/locales.json | 3 +-- 4 files changed, 7 insertions(+), 11 deletions(-) diff --git a/ChangeLog b/ChangeLog index 5331f4f..20cae09 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,4 +1,5 @@ Changes in version 0.0.4 - UNRELEASED: + * Bug 21927: Remove the ability to install/update the hardened bundle. * Bug 21244: Update the MAR signing key for 7.0. * Bug 21536: Remove asn's scramblesuit bridge from Tor Browser. * Fix compilation with Go 1.8. diff --git a/data/installer/urls.json b/data/installer/urls.json index bbfcdeb..7223654 100644 --- a/data/installer/urls.json +++ b/data/installer/urls.json @@ -1,22 +1,18 @@ { "downloadsURLs": { "release": "https://aus1.torproject.org/torbrowser/update_2/release/downloads.json", - "alpha": "https://aus1.torproject.org/torbrowser/update_2/alpha/downloads.json", - "hardened": "https://aus1.torproject.org/torbrowser/update_2/hardened/downloads.json" + "alpha": "https://aus1.torproject.org/torbrowser/update_2/alpha/downloads.json" }, "downloadsOnions": { "release": "http://x3nelbld33llasqv.onion/torbrowser/update_2/release/downloads.json", - "alpha": "http://x3nelbld33llasqv.onion/torbrowser/update_2/alpha/downloads.json", - "hardened": "http://x3nelbld33llasqv.onion/torbrowser/update_2/hardened/downloads.json" + "alpha": "http://x3nelbld33llasqv.onion/torbrowser/update_2/alpha/downloads.json" }, "updateURLs": { "release": "https://aus1.torproject.org/torbrowser/update_2/release", - "alpha": "https://aus1.torproject.org/torbrowser/update_2/alpha", - "hardened": "https://aus1.torproject.org/torbrowser/update_2/hardened" + "alpha": "https://aus1.torproject.org/torbrowser/update_2/alpha" }, "updateOnions": { "release": "http://x3nelbld33llasqv.onion/torbrowser/update_2/release", - "alpha": "http://x3nelbld33llasqv.onion/torbrowser/update_2/alpha", - "hardened": "http://x3nelbld33llasqv.onion/torbrowser/update_2/hardened" + "alpha": "http://x3nelbld33llasqv.onion/torbrowser/update_2/alpha" } } diff --git a/data/ui/channels.json b/data/ui/channels.json index 8e78f46..5dfbd9f 100644 --- a/data/ui/channels.json +++ b/data/ui/channels.json @@ -1,3 +1,3 @@ { - "linux64": [ "release", "alpha", "hardened" ] + "linux64": [ "release", "alpha" ] } diff --git a/data/ui/locales.json b/data/ui/locales.json index ec48d2b..42adfac 100644 --- a/data/ui/locales.json +++ b/data/ui/locales.json @@ -1,5 +1,4 @@ { "release": [ "en-US", "ar", "de", "es-ES", "fa", "fr", "it", "ja", "ko", "nl", "pl", "pt-PT", "ru", "tr", "vi", "zh-CN" ], - "alpha": [ "en-US", "ar", "de", "es-ES", "fa", "fr", "it", "ja", "ko", "nl", "pl", "pt-PT", "ru", "tr", "vi", "zh-CN" ], - "hardened": [ "ALL"] + "alpha": [ "en-US", "ar", "de", "es-ES", "fa", "fr", "it", "ja", "ko", "nl", "pl", "pt-PT", "ru", "tr", "vi", "zh-CN" ] }
