+Changes in version 0.3.5.2-alpha - 2018-09-2?
|
|
|
+ Tor 0.3.5.2-alpha fixes several bugs in 0.3.5.1-alpha, including one
|
|
|
+ that made Tor think it had run out of sockets. Anybody running a relay
|
|
|
+ or an onion service on 0.3.5.1-alpha should upgrade.
|
|
|
+
|
|
|
+ o Major bugfixes (relay bandwidth statistics):
|
|
|
+ - When we close relayed circuits, report the data in the circuit
|
|
|
+ queues as being written in our relay bandwidth stats. This
|
|
|
+ mitigates guard discovery and other attacks that close circuits
|
|
|
+ for the explicit purpose of noticing this discrepancy in
|
|
|
+ statistics. Fixes bug 23512; bugfix on 0.0.8pre3.
|
|
|
+
|
|
|
+ o Major bugfixes (socket accounting):
|
|
|
+ - In our socket accounting code, count a socket as closed even when
|
|
|
+ it is closed indirectly by the TLS layer. Previously, we would
|
|
|
+ count these sockets as still in use, and incorrectly believe that
|
|
|
+ we had run out of sockets. Fixes bug 27795; bugfix
|
|
|
+ on 0.3.5.1-alpha.
|
|
|
+
|
|
|
+ o Minor bugfixes (32-bit OSX and iOS, timing):
|
|
|
+ - Fix an integer overflow bug in our optimized 32-bit millisecond-
|
|
|
+ difference algorithm for 32-bit Apple platforms. Previously, it
|
|
|
+ would overflow when calculating the difference between two times
|
|
|
+ more than 47 days apart. Fixes part of bug 27139; bugfix
|
|
|
+ on 0.3.4.1-alpha.
|
|
|
+ - Improve the precision of our 32-bit millisecond difference
|
|
|
+ algorithm for 32-bit Apple platforms. Fixes part of bug 27139;
|
|
|
+ bugfix on 0.3.4.1-alpha.
|
|
|
+ - Relax the tolerance on the mainloop/update_time_jumps test when
|
|
|
+ running on 32-bit Apple platforms. Fixes part of bug 27139; bugfix
|
|
|
+ on 0.3.4.1-alpha.
|
|
|
+
|
|
|
+ o Minor bugfixes (onion service v3):
|
|
|
+ - Close all SOCKS request (for the same .onion) if the newly fetched
|
|
|
+ descriptor is unusable. Before that, we would close only the first
|
|
|
+ one leaving the other hanging and let to time out by themselves.
|
|
|
+ Fixes bug 27410; bugfix on 0.3.2.1-alpha.
|
|
|
+
|
|
|
+ o Minor bugfixes (memory leak):
|
|
|
+ - Fix an unlikely memory leak when trying to read a private key from
|
|
|
+ a ridiculously large file. Fixes bug 27764; bugfix on
|
|
|
+ 0.3.5.1-alpha. This is CID 1439488.
|
|
|
+
|
|
|
+ o Minor bugfixes (NSS):
|
|
|
+ - Correctly detect failure to open a dummy TCP socket when stealing
|
|
|
+ ownership of an fd from the NSS layer. Fixes bug 27782; bugfix
|
|
|
+ on 0.3.5.1-alpha.
|
|
|
+
|
|
|
+ o Minor bugfixes (rust):
|
|
|
+ - protover_all_supported() would attempt to allocate up to 16GB on
|
|
|
+ some inputs, leading to a potential memory DoS. Fixes bug 27206;
|
|
|
+ bugfix on 0.3.3.5-rc.
|
|
|
+
|
|
|
+ o Minor bugfixes (testing):
|
|
|
+ - Revise the "conditionvar_timeout" test so that it succeeds even on
|
|
|
+ heavily loaded systems where the test threads are not scheduled
|
|
|
+ within 200 msec. Fixes bug 27073; bugfix on 0.2.6.3-alpha.
|
|
|
+
|
|
|
+ o Code simplification and refactoring:
|
|
|
+ - Divide the routerlist.c and dirserv.c modules into smaller parts.
|
|
|
+ Closes ticket 27799.
