commit fa3ac404e97e5dcb25e31e9ec7dfddf229714d22 Author: Georg Koppen <gk(a)torproject.org> Date: Fri Dec 19 10:38:33 2014 +0000 Updating the README.build. This update takes account of the changes landed in #13379 and earlier updater related bugs. It removes the section with spurious hangs during builds as the underlying libfaketime problems should be fixed with the switch to a newer libfaketime providing a more fine-grained control via FAKETIME_SKIP_CMDS and friends. --- gitian/README.build | 40 ++++++++++++++++++++++++---------------- 1 file changed, 24 insertions(+), 16 deletions(-) diff --git a/gitian/README.build b/gitian/README.build index 24a67a8..670e84c 100644 --- a/gitian/README.build +++ b/gitian/README.build @@ -46,15 +46,19 @@ Detailed Explanation of Scripts: several helper scripts to make things easier. 0.

[tor-browser-bundle/master] Bug 13379: Sign our MAR files.
by brade＠torproject.org 18 Dec '14

18 Dec '14

commit d852329ac0979d8005e9e8bdd9b3f8a049fc2db4 Author: Kathy Brade <brade(a)pearlcrescent.com> Date: Wed Dec 17 16:57:28 2014 -0500 Bug 13379: Sign our MAR files. In the Linux mar-tools package, include certutil, signmar, and the required NSS and NSPR libraries. Change update_responses to select the action to be done based on the program name, thereby separating the incremental MAR file generation (done via a new 'gen_incrementals' symlink) from the htdocs generation. Also added an 'update_responses' make target. Thanks to boklm for help with this. Add a series of 'signmar' make targets which run a new signmars.sh script, which does the following: 1. Prompts for an NSS password (the script assumes that an nssdb directory exists that contains the signing key/cert). 2. Moves original (unsigned) MAR files to a TORBROWSER_VERSION-unsigned/ directory. 3. Signs each of the MAR files, placing the signed files in the TORBROWSER_VERSION/ directory. You may set NSS_DB_DIR and/or NSS_CERTNAME before running signmars.sh; the defaults are ./nssdb and marsigner --- gitian/Makefile | 15 +++ gitian/descriptors/linux/gitian-firefox.yml | 11 +++ gitian/signmars.sh | 135 +++++++++++++++++++++++++++ tools/update-responses/gen_incrementals | 1 + tools/update-responses/update_responses | 34 +++++-- 5 files changed, 189 insertions(+), 7 deletions(-) diff --git a/gitian/Makefile b/gitian/Makefile index 2c17656..9613db6 100644 --- a/gitian/Makefile +++ b/gitian/Makefile @@ -33,6 +33,21 @@ build-beta: ./hash-bundles.sh versions.beta incrementals: + ../tools/update-responses/gen_incrementals + +signmars: + ./signmars.sh versions + +signmars-alpha: + ./signmars.sh versions.alpha + +signmars-beta: + ./signmars.sh versions.beta + +signmars-nightly: + ./signmars.sh versions.nightly + +update_responses: ../tools/update-responses/update_responses hash: diff --git a/gitian/descriptors/linux/gitian-firefox.yml b/gitian/descriptors/linux/gitian-firefox.yml index 5f96b6e..a1abf2e 100644 --- a/gitian/descriptors/linux/gitian-firefox.yml +++ b/gitian/descriptors/linux/gitian-firefox.yml @@ -136,12 +136,23 @@ script: | rm -f $INSTDIR/Browser/*.chk # # Make MAR-based update tools available for use during the bundle phase. + # Note that mar and mbsdiff are standalone tools, compiled for the build + # host's architecture.

[tor-browser/tor-browser-31.3.0esr-4.5-1] Bug 13379: Sign our MAR files.
by brade＠torproject.org 18 Dec '14

18 Dec '14

commit 7612aeba131f3eca1c80a369aab97da6fc249565 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-signmar (build the signmar tool). 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 (Mozilla plans to use OS-native APIs on Mac OS and they already do so on 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 all platforms. Use SHA512-based MAR signatures instead of the SHA1-based ones that Mozilla uses. This is implemented inside MAR_USE_SHA512_RSA_SIG #ifdef's and with a signature algorithm ID of 512 to help avoid collisions with future work Mozilla might do in this area.

commit fc1c9ff7c1b2defdbc039f12214767608f46423f Author: Gunes Acar <gunes.acar(a)esat.kuleuven.be> Date: Wed Dec 3 20:22:22 2014 +0100 Bug 13439: No canvas prompt for content-callers.
