[tor-dev] [Proposal] A simple way to make Tor-Browser-Bundle more portable and secure

[Daniel Simon <ddanielsimonn@xxxxxxxxx>]

Hello.

How it's currently done - The Tor Browser Bundle is dynamically linked
against glibc.

Security problem - The Tor Browser Bundle has the risk of information
about the host system's library ecosystem leaking out onto the
network.

Portability problem - The Tor Browser Bundle can't be run on systems
that don't use glibc, making it unusable due to different syscalls.

Solution proposed - Static link the Tor Browser Bundle with musl
libc.[1] It is a simple and fast libc implementation that was
especially crafted for static linking. This would solve both security
and portability issues.

What is Tor developers' opinion about this? I personally don't see any
drawbacks and would be interested in discussing this further.

Sincerely,
Daniel
