Resolves ticket 11438.
|
||||
|
||||
o Major bugfixes (undefined behavior):
|
||||
- Fix various instances of undefined behavior in channeltls.c,
|
||||
tor_memmem(), and eventdns.c, that would cause us to construct
|
||||
pointers to memory outside an allocated object. (These invalid
|
||||
pointers were not accessed, but C does not even allow them to
|
||||
exist.) Fixes bug #10363; bugfixes on 0.2.0.10-alpha,
|
||||
0.2.3.6-alpha, 0.1.1.1-alpha, and 0.1.2.1-alpha. Reported by
|
||||
"bobnomnom".
|
||||
- Use the AddressSanitizer and Ubsan sanitizers (in clang-3.4) to
|
||||
fix some miscellaneous errors in our tests and codebase. Fix for
|
||||
bug 11232. Bugfixes on versions back as far as 0.2.1.11-alpha.
|
||||
|
||||
o Minor features (Transparent proxy, *BSD):
|
||||
- Support FreeBSD's ipfw firewall interface for TransPort ports. on
|
||||
FreeBSD. To enable it, set "TransProxyType ipfw". Resolves ticket

memory. Right now, this includes AddressSanitizer and UbSan, which
|

are supported in newer versions of GCC and Clang. Closes ticket

11477.
|

- If you don't specify MaxMemInQueues yourself, Tor now tries to
|
||||
pick a good value based on your total system memory. Previously,
|
||||
the default was always 8 GB. You can still override the default by
|
||||
setting MaxMemInQueues yourself. Resolves ticket 11396.
|

new external IP address, and publish a new descriptor with the new
|

IP address if it changed. Resolves ticket 2454.

real limit is now exposed via GETINFO limits/max-mem-in-queues.
|
||||
|
||||
o Minor features (misc):
|
||||
- Always check return values for unlink, munmap, UnmapViewOfFile;
|
||||
check strftime return values more often. In some cases all we can
|
||||
do is report a warning, but this may help prevent deeper bugs from
|
||||
going unnoticed. Closes ticket 8787.
|
||||
- Fix numerous warnings from the clang "scan-build" static analyzer.
|
||||
Some of these are programming style issues; some of them are false
|
||||
positives that indicated awkward code; some are undefined behavior
|
||||
cases related to constructing (but not using) invalid pointers;
|
||||
some are assumptions about API behavior; some are using
|
||||
sizeof(ptr) when sizeof(*ptr) would be correct; and one or two are
|
||||
genuine bugs that weren't reachable from the rest of the program.
|
||||
Fixes bug 8793; bugfixes on many, many tor versions.
|
||||
|

o Minor features (bridge client):
|

- Report a more useful failure message when we can't connect to a

bridge because we don't have the right pluggable transport

o Minor bugfixes (logging):

o Minor bugfixes (client, DNSPort):
|
||||
- When using DNSPort, try to respond to AAAA requests with AAAA
|

answers. Previously, we hadn't looked at the request type when
|
||||
deciding which answer type to prefer. Fixes bug 10468; bugfix on
|
||||
0.2.4.7-alpha.
|
||||
- When receiving a DNS query for an unsupported record type, reply
|
||||
with no answer rather than with a NOTIMPL error. This behavior
|
||||
isn't correct either, but it will break fewer client programs, we
|
||||
hope. Fixes bug 10268; bugfix on 0.2.0.1-alpha. Original patch
|
||||
from "epoch".
|
||||
|
||||
o Minor bugfixes (exit):
|
||||
- Stop leaking memory when we successfully resolve a PTR record.
|
||||
Fixes bug 11437; bugfix on 0.2.4.7-alpha.
|
||||
|
||||
o Minor bugfixes (bridge client):
|
||||
- Stop accepting bridge lines containing hostnames. Doing so would
|
||||
cause clients to perform DNS requests on the hostnames, which was
|
||||
not sensible behavior. Fixes bug 10801; bugfix on 0.2.0.1-alpha.
|
||||
- Avoid a 60-second delay in the bootstrapping process when a Tor
|
||||
client with pluggable transports re-reads its configuration at
|
||||
just the wrong time. Re-fixes bug 11156; bugfix on 0.2.5.3-alpha.
|
||||
- Avoid 60-second delays in the bootstrapping process when Tor is
|
||||
launching for a second time while using bridges. Fixes bug 9229;
|
||||
bugfix on 0.2.0.3-alpha.
|
||||
|
||||
o Minor bugfixes (client, logging during bootstrap):
|
||||
- Warn only once we start logging in an unsafe way. Previously, we
|
||||
complain as many times we had problems. Fix for #9870; bugfix on
|
||||
0.2.5.1-alpha.
|
||||
- Using the Linux seccomp2 sandbox no longer prevents stack-trace
|
||||
logging on crashes or errors. Fixes part 11465; bugfix on
|
||||
0.2.5.1-alpha.
|
||||
- Only report the first fatal bootstrap error on a given OR
|
||||
connection. This stops us from telling the controller bogus error
|
||||
messages like "DONE". Fixes bug 10431; bugfix on 0.2.1.1-alpha.
