Nick Mathewson fb91d647ac Downgrade 'invalid result from curve25519 handshake: 4' warning
Also, refactor the way we handle failed handshakes so that this
warning doesn't propagate itself to "onion_skin_client_handshake
failed" and "circuit_finish_handshake failed" and
"connection_edge_process_relay_cell (at origin) failed."

Resolves warning from 9635.

Nick Mathewson af73d3e4d8 Disable SSLv3 unconditionally. Closes ticket 13426.
The POODLE attack doesn't affect Tor, but there's no reason to tempt
fate: SSLv3 isn't going to get any better.

Nick Mathewson 09951bea7f Don't use the getaddrinfo sandbox cache from tor-resolve
Fixes bug 13295; bugfix on 0.2.5.3-alpha.

The alternative here is to call crypto_global_init() from tor-resolve,
but let's avoid linking openssl into tor-resolve for as long as we
can.

Roger Dingledine 0c3b3650aa clients now send correct address for rendezvous point
Clients now send the correct address for their chosen rendezvous point
when trying to access a hidden service. They used to send the wrong
address, which would still work some of the time because they also
sent the identity digest of the rendezvous point, and if the hidden
service happened to try connecting to the rendezvous point from a relay
that already had a connection open to it, the relay would reuse that
connection. Now connections to hidden services should be more robust
and faster. Also, this bug meant that clients were leaking to the hidden
service whether they were on a little-endian (common) or big-endian (rare)
system, which for some users might have reduced their anonymity.

Fixes bug 13151; bugfix on 0.2.1.5-alpha.

Roger Dingledine 6215ebb266 Reduce log severity for unused ClientTransportPlugin lines
Tor Browser includes several ClientTransportPlugin lines in its

Nick Mathewson 3c2c6a6116 In routerlist_assert_ok(), check r2 before taking &(r2->cache_info)
Technically, we're not allowed to take the address of a member can't
exist relative to the null pointer.  That makes me wonder how any sane
compliant system implements the offsetof macro, but let's let sleeping
balrogs lie.

Roger Dingledine 37a76d75dd Resume expanding abbreviations for command-line options
The fix for bug 4647 accidentally removed our hack from bug 586 that
rewrote HashedControlPassword to __HashedControlSessionPassword when
it appears on the commandline (which allowed the user to set her own
HashedControlPassword in the torrc file while the controller generates
a fresh session password for each run).

Two bugs here:

  2) relay_command_to_string() didn't log the value of unrecognized
     commands.

Both fixed here.

Also adds an ExtORPortCookieAuthFileGroupReadable, since there's no
reason not to.

Roger Dingledine fcac4b4467 Build circuits more readily when DisableNetwork goes to 0
When Tor starts with DisabledNetwork set, it would correctly

when DisableNetwork is set to 0. Fixes the bug introduced by the
fix for bug 11200; bugfix on 0.2.5.4-alpha.

intrigeri 0a70579784 Verify configuration file via ExecStartPre in the systemd unit file (#12730). 2014-07-30 16:56:55 +00:00
intrigeri 8b470ee4b5 Explicitly disable RunAsDaemon in the systemd unit file (#12731).
Our current systemd unit uses "Type = simple", so systemd does not expect tor to
fork. If the user has "RunAsDaemon 1" in their torrc, then things won't work as
expected. This is e.g. the case on Debian (and derivatives), since there we pass
"--defaults-torrc /usr/share/tor/tor-service-defaults-torrc" (that contains
"RunAsDaemon 1") by default.

The only solution I could find is to explicitly pass "--RunAsDaemon 0" when
starting tor from the systemd unit file, which this commit does.
