Remember, you can't check to see if there are N bytes left in a
buffer by doing (buf + N < end), since the buf + N computation might
take you off the end of the buffer and result in undefined behavior.
Fixes 28202; bugfix on 0.2.0.3-alpha.
It is not enough to look at protover for v3 rendezvous support but also we
need to make sure that the curve25519 onion key is present or in other words
that the descriptor has been fetched and does contain it.

Treat backtrace test failures as expected on NetBSD, OpenBSD, and
macOS/Darwin, until we solve bug 17808.
(FreeBSD failures have been treated as expected since 18204 in 0.2.8.)
Fixes bug 27948; bugfix on 0.2.5.2-alpha.
Occasionally, key pinning doesn't catch a relay that shares an ed25519
ID with another relay. Log the identity fingerprints and the shared
ed25519 ID when this happens, instead of making a BUG() warning.
Fixes bug 27800; bugfix on 0.3.2.1-alpha.
Commit 488e2b00bf introduced an issue, most
likely introduced by a bad copy paste, that made us stop reading on the
connection if our write bandwidth limit was reached.
The problem is that because "read_blocked_on_bw" was never set, the connection
was never reenabled for reading.
This is most likely the cause of #27813 where bytes were accumulating in the
kernel TCP bufers because tor was not doing reads. Only relays with
RelayBandwidthRate would suffer from this but affecting all relays connecting
to them. And using that tor option is recommended and best practice so many
many relays have it enabled.
Fixes#28089.
It turns out that if _only_ the ControlPort is set and nothing else, tor would
simply not bootstrap and thus not start properly. Commit 67a41b6306
removed that requirement for tor to be considered a "client".
Unfortunately, this made the mainloop enable basically nothing if only the
ControlPort is set in the torrc.
This commit now makes it that we also consider the ControlPort when deciding
if we are a Client or not. It does not revert 67a41b6306 meaning
options_any_client_port_set() stays the same, not looking at the control port.
Fixes#27849.
