+Changes in version 0.2.0.32 - 2008-11-20
|
|
|
+ o Security fixes:
|
|
|
+ - The "User" and "Group" config options did not clear the
|
|
|
+ supplementary group entries for the Tor process. The "User" option
|
|
|
+ is now more robust, and we now set the groups to the specified
|
|
|
+ user's primary group. The "Group" option is now ignored. For more
|
|
|
+ detailed logging on credential switching, set CREDENTIAL_LOG_LEVEL
|
|
|
+ in common/compat.c to LOG_NOTICE or higher. Patch by Jacob Appelbaum
|
|
|
+ and Steven Murdoch. Bugfix on 0.0.2pre14. Fixes bug 848 and 857.
|
|
|
+ - The "ClientDNSRejectInternalAddresses" config option wasn't being
|
|
|
+ consistently obeyed: if an exit relay refuses a stream because its
|
|
|
+ exit policy doesn't allow it, we would remember what IP address
|
|
|
+ the relay said the destination address resolves to, even if it's
|
|
|
+ an internal IP address. Bugfix on 0.2.0.7-alpha; patch by rovv.
|
|
|
+
|
|
|
+ o Major bugfixes:
|
|
|
+ - Fix a DOS opportunity during the voting signature collection process
|
|
|
+ at directory authorities. Spotted by rovv. Bugfix on 0.2.0.x.
|
|
|
+
|
|
|
+ o Major bugfixes (hidden services):
|
|
|
+ - When fetching v0 and v2 rendezvous service descriptors in parallel,
|
|
|
+ we were failing the whole hidden service request when the v0
|
|
|
+ descriptor fetch fails, even if the v2 fetch is still pending and
|
|
|
+ might succeed. Similarly, if the last v2 fetch fails, we were
|
|
|
+ failing the whole hidden service request even if a v0 fetch is
|
|
|
+ still pending. Fixes bug 814. Bugfix on 0.2.0.10-alpha.
|
|
|
+ - When extending a circuit to a hidden service directory to upload a
|
|
|
+ rendezvous descriptor using a BEGIN_DIR cell, almost 1/6 of all
|
|
|
+ requests failed, because the router descriptor has not been
|
|
|
+ downloaded yet. In these cases, do not attempt to upload the
|
|
|
+ rendezvous descriptor, but wait until the router descriptor is
|
|
|
+ downloaded and retry. Likewise, do not attempt to fetch a rendezvous
|
|
|
+ descriptor from a hidden service directory for which the router
|
|
|
+ descriptor has not yet been downloaded. Fixes bug 767. Bugfix
|
|
|
+ on 0.2.0.10-alpha.
|
|
|
+
|
|
|
+ o Minor bugfixes:
|
|
|
+ - Fix several infrequent memory leaks spotted by Coverity.
|
|
|
+ - When testing for libevent functions, set the LDFLAGS variable
|
|
|
+ correctly. Found by Riastradh.
|
|
|
+ - Avoid a bug where the FastFirstHopPK 0 option would keep Tor from
|
|
|
+ bootstrapping with tunneled directory connections. Bugfix on
|
|
|
+ 0.1.2.5-alpha. Fixes bug 797. Found by Erwin Lam.
|
|
|
+ - When asked to connect to A.B.exit:80, if we don't know the IP for A
|
|
|
+ and we know that server B rejects most-but-not all connections to
|
|
|
+ port 80, we would previously reject the connection. Now, we assume
|
|
|
+ the user knows what they were asking for. Fixes bug 752. Bugfix
|
|
|
+ on 0.0.9rc5. Diagnosed by BarkerJr.
|
|
|
+ - If we overrun our per-second write limits a little, count this as
|
|
|
+ having used up our write allocation for the second, and choke
|
|
|
+ outgoing directory writes. Previously, we had only counted this when
|
|
|
+ we had met our limits precisely. Fixes bug 824. Patch from by rovv.
|
|
|
+ Bugfix on 0.2.0.x (??).
|
|
|
+ - Remove the old v2 directory authority 'lefkada' from the default
|
|
|
+ list. It has been gone for many months.
|
|
|
+ - Stop doing unaligned memory access that generated bus errors on
|
|
|
+ sparc64. Bugfix on 0.2.0.10-alpha. Fixes bug 862.
|
|
|
+ - Make USR2 log-level switch take effect immediately. Bugfix on
|
|
|
+ 0.1.2.8-beta.
|
|
|
+
|
|
|
+ o Minor bugfixes (controller):
|
|
|
+ - Make DNS resolved events into "CLOSED", not "FAILED". Bugfix on
|
|
|
+ 0.1.2.5-alpha. Fix by Robert Hogan. Resolves bug 807.
