+Changes in version 0.1.2.18 - 2007-10-28
|
|
|
+ Tor 0.1.2.18 fixes many problems including crash bugs, problems with
|
|
|
+ hidden service introduction that were causing huge delays, and a big
|
|
|
+ bug that was causing some servers to disappear from the network status
|
|
|
+ lists for a few hours each day.
|
|
|
+
|
|
|
+ o Major bugfixes (crashes):
|
|
|
+ - If a connection is shut down abruptly because of something that
|
|
|
+ happened inside connection_flushed_some(), do not call
|
|
|
+ connection_finished_flushing(). Should fix bug 451:
|
|
|
+ "connection_stop_writing: Assertion conn->write_event failed"
|
|
|
+ Bugfix on 0.1.2.7-alpha.
|
|
|
+ - Fix possible segfaults in functions called from
|
|
|
+ rend_process_relay_cell().
|
|
|
+
|
|
|
+ o Major bugfixes (hidden services):
|
|
|
+ - Hidden services were choosing introduction points uniquely by
|
|
|
+ hexdigest, but when constructing the hidden service descriptor
|
|
|
+ they merely wrote the (potentially ambiguous) nickname.
|
|
|
+ - Clients now use the v2 intro format for hidden service
|
|
|
+ connections: they specify their chosen rendezvous point by identity
|
|
|
+ digest rather than by (potentially ambiguous) nickname. These
|
|
|
+ changes could speed up hidden service connections dramatically.
|
|
|
+
|
|
|
+ o Major bugfixes (other):
|
|
|
+ - Stop publishing a new server descriptor just because we get a
|
|
|
+ HUP signal. This led (in a roundabout way) to some servers getting
|
|
|
+ dropped from the networkstatus lists for a few hours each day.
|
|
|
+ - When looking for a circuit to cannibalize, consider family as well
|
|
|
+ as identity. Fixes bug 438. Bugfix on 0.1.0.x (which introduced
|
|
|
+ circuit cannibalization).
|
|
|
+ - When a router wasn't listed in a new networkstatus, we were leaving
|
|
|
+ the flags for that router alone -- meaning it remained Named,
|
|
|
+ Running, etc -- even though absence from the networkstatus means
|
|
|
+ that it shouldn't be considered to exist at all anymore. Now we
|
|
|
+ clear all the flags for routers that fall out of the networkstatus
|
|
|
+ consensus. Fixes bug 529.
|
|
|
+
|
|
|
+ o Minor bugfixes:
|
|
|
+ - Don't try to access (or alter) the state file when running
|
|
|
+ --list-fingerprint or --verify-config or --hash-password. Resolves
|
|
|
+ bug 499.
|
|
|
+ - When generating information telling us how to extend to a given
|
|
|
+ router, do not try to include the nickname if it is
|
|
|
+ absent. Resolves bug 467.
|
|
|
+ - Fix a user-triggerable segfault in expand_filename(). (There isn't
|
|
|
+ a way to trigger this remotely.)
|
|
|
+ - When sending a status event to the controller telling it that an
|
|
|
+ OR address is readable, set the port correctly. (Previously we
|
|
|
+ were reporting the dir port.)
|
|
|
+ - Fix a minor memory leak whenever a controller sends the PROTOCOLINFO
|
|
|
+ command. Bugfix on 0.1.2.17.
|
|
|
+ - When loading bandwidth history, do not believe any information in
|
|
|
+ the future. Fixes bug 434.
|
|
|
+ - When loading entry guard information, do not believe any information
|
|
|
+ in the future.
|
|
|
+ - When we have our clock set far in the future and generate an
|
|
|
+ onion key, then re-set our clock to be correct, we should not stop
|
|
|
+ the onion key from getting rotated.
|
|
|
+ - On some platforms, accept() can return a broken address. Detect
|
|
|
+ this more quietly, and deal accordingly. Fixes bug 483.
|
|
|
+ - It's not actually an error to find a non-pending entry in the DNS
|
|
|
+ cache when canceling a pending resolve. Don't log unless stuff
|
|
|
+ is fishy. Resolves bug 463.
|
|
|
+ - Don't reset trusted dir server list when we set a configuration
|
|
|
+ option. Patch from Robert Hogan.
