Merge branch 'bug40390_035_squashed' into maint-0.3.5

parents 520d5c10 c0aa9e0a
o Major bugfixes (security, defense-in-depth):
- Detect a wider variety of failure conditions from the OpenSSL RNG
code. Previously, we would detect errors from a missing RNG
implementation, but not failures from the RNG code itself.
Fortunately, it appears those failures do not happen in practice
when Tor is using OpenSSL's default RNG implementation.
Fixes bug 40390; bugfix on 0.2.8.1-alpha. This issue is also tracked as
TROVE-2021-004. Reported by Jann Horn at Google's Project Zero.
