Changes in version 0.4.1.6 - 2019-09-19
This release backports several bugfixes to improve stability and
correctness. Anyone experiencing build problems or crashes with 0.4.1.5,
or experiencing reliability issues with single onion services, should
upgrade.
o Major bugfixes (crash, Linux, Android, backport from 0.4.2.1-alpha):
- Tolerate systems (including some Android installations) where
madvise and MADV_DONTDUMP are available at build-time, but not at
run time. Previously, these systems would notice a failed syscall
and abort. Fixes bug 31570; bugfix on 0.4.1.1-alpha.
- Tolerate systems (including some Linux installations) where
madvise and/or MADV_DONTFORK are available at build-time, but not
at run time. Previously, these systems would notice a failed
syscall and abort. Fixes bug 31696; bugfix on 0.4.1.1-alpha.
o Minor features (stem tests, backport from 0.4.2.1-alpha):
- Change "make test-stem" so it only runs the stem tests that use
tor. This change makes test-stem faster and more reliable. Closes
ticket 31554.
o Minor bugfixes (build system, backport form 0.4.2.1-alpha):
- Do not include the deprecated <sys/sysctl.h> on Linux or Windows
systems. Fixes bug 31673; bugfix on 0.2.5.4-alpha.
o Minor bugfixes (compilation, backport from 0.4.2.1-alpha):
- Add more stub functions to fix compilation on Android with link-
time optimization when --disable-module-dirauth is used.
Previously, these compilation settings would make the compiler
look for functions that didn't exist. Fixes bug 31552; bugfix
on 0.4.1.1-alpha.
- Suppress spurious float-conversion warnings from GCC when calling
floating-point classifier functions on FreeBSD. Fixes part of bug
31687; bugfix on 0.3.1.5-alpha.
o Minor bugfixes (controller protocol):
- Fix the MAPADDRESS controller command to accept one or more
arguments. Previously, it required two or more arguments, and ignored
the first. Fixes bug 31772; bugfix on 0.4.1.1-alpha.
o Minor bugfixes (guards, backport from 0.4.2.1-alpha):
- When tor is missing descriptors for some primary entry guards,
make the log message less alarming. It's normal for descriptors to
expire, as long as tor fetches new ones soon after. Fixes bug
31657; bugfix on 0.3.3.1-alpha.
o Minor bugfixes (logging, backport from 0.4.2.1-alpha):
- Change log level of message "Hash of session info was not as
expected" to LOG_PROTOCOL_WARN. Fixes bug 12399; bugfix
on 0.1.1.10-alpha.
o Minor bugfixes (rust, backport from 0.4.2.1-alpha):
- Correctly exclude a redundant rust build job in Travis. Fixes bug
31463; bugfix on 0.3.5.4-alpha.
o Minor bugfixes (v2 single onion services, backport from 0.4.2.1-alpha):
- Always retry v2 single onion service intro and rend circuits with
a 3-hop path. Previously, v2 single onion services used a 3-hop
path when rendezvous circuits were retried after a remote or
delayed failure, but a 1-hop path for immediate retries. Fixes bug
23818; bugfix on 0.2.9.3-alpha.
o Minor bugfixes (v3 single onion services, backport from 0.4.2.1-alpha):
- Always retry v3 single onion service intro and rend circuits with
a 3-hop path. Previously, v3 single onion services used a 3-hop
path when rend circuits were retried after a remote or delayed
failure, but a 1-hop path for immediate retries. Fixes bug 23818;
bugfix on 0.3.2.1-alpha.
- Make v3 single onion services fall back to a 3-hop intro, when all
intro points are unreachable via a 1-hop path. Previously, v3
single onion services failed when all intro nodes were unreachable
via a 1-hop path. Fixes bug 23507; bugfix on 0.3.2.1-alpha.
o Documentation (backport from 0.4.2.1-alpha):
- Use RFC 2397 data URL scheme to embed an image into tor-exit-
notice.html so that operators no longer have to host it
themselves. Closes ticket 31089.
