Changes in version 0.4.7.8 - 2022-06-17
This version fixes several bugfixes including a High severity security issue
categorized as a Denial of Service. Everyone running an earlier version
should upgrade to this version.
o Major bugfixes (congestion control, TROVE-2022-001):
- Fix a scenario where RTT estimation can become wedged, seriously
degrading congestion control performance on all circuits. This
impacts clients, onion services, and relays, and can be triggered
remotely by a malicious endpoint. Tracked as CVE-2022-33903. Fixes
bug 40626; bugfix on 0.4.7.5-alpha.
o Minor features (fallbackdir):
- Regenerate fallback directories generated on June 17, 2022.
o Minor features (geoip data):
- Update the geoip files to match the IPFire Location Database, as
retrieved on 2022/06/17.
o Minor bugfixes (linux seccomp2 sandbox):
- Allow the rseq system call in the sandbox. This solves a crash
issue with glibc 2.35 on Linux. Patch from pmu-ipf. Fixes bug
40601; bugfix on 0.3.5.11.
o Minor bugfixes (logging):
- Demote a harmless warn log message about finding a second hop to
from warn level to info level, if we do not have enough
descriptors yet. Leave it at notice level for other cases. Fixes
bug 40603; bugfix on 0.4.7.1-alpha.
- Demote a notice log message about "Unexpected path length" to info
level. These cases seem to happen arbitrarily, and we likely will
never find all of them before the switch to arti. Fixes bug 40612;
bugfix on 0.4.7.5-alpha.
o Minor bugfixes (relay, logging):
- Demote a harmless XOFF log message to from notice level to info
level. Fixes bug 40620; bugfix on 0.4.7.5-alpha.
