Issue created Dec 15, 2013 by intrigeri@intrigeriMaintainer

Drop sqlite3, nss and nspr backports from our APT repository

Originally created by @intrigeri on #6496 (Redmine)

In bugfix/use-our-own-sqlite we have imported libnss3, libnss3-1d, libnspr4, libnspr4-0d, libsqlite3-0 and sqlite3 backports into our APT repository, as:

  1. our current browser (24.2.0esr-0+tails3~bpo60+1) depends on these packages;
  2. these packages were dropped from mozilla.debian.net’s squeeze-backports repository.

This workaround will (hopefully) be useless once we rebase the browser on Iceweasel 24.2.0esr-1.

Dropping these packages will make us install an old, unsafe version of NSS. We should therefore check that Iceweasel does not use the system one:

  • xulrunner 24.2.0esr-1 ships /usr/lib/xulrunner-24.0/libnss3.so, which the –0 one does not
  • xulrunner 24.2.0esr-1’s ldd /usr/lib/xulrunner-24.0/libxul.so says it is linked on the system /usr/lib/libnss3.so, but it says /usr/lib/xulrunner-24.0/libxul.so: /usr/lib/libsmime3.so: version `NSS_3.15' not found (required by /usr/lib/xulrunner-24.0/libxul.so); does this mean it won’t / can’t use the system NSS?
  • On Tails 0.22, lsof | grep nss | grep icew says it has loaded /lib/libnss_{nis,files,compat}, /usr/lib/libnss3.so and various libs from /usr/lib/nss/; while with 24.2.0esr-1, it has loaded /lib/libnss_{nis,files,compat} and /usr/lib/xulrunner-24.0/libnss*.so, so we should be safe.

Still, other apps will be using an old, unsafe NSS. Only Pidgin depends on this package. We should probably upload a fixed version to squeeze-backports: #6497 (closed).
