Fix a set of false positives where relays would consider connections
to other relays as being client-only connections (and thus e.g.
deserving different link padding schemes) if those relays fell out
of the consensus briefly.
Now we look only at the initial handshake and whether the connection
authenticated as a relay.
Fixes bug 24898; bugfix on 0.3.1.1-alpha.
New-style (v3) onion services now obey the "max rendezvous circuit
attempts" logic.
Previously they would make as many rendezvous circuit attempts as they
could fit in the MAX_REND_TIMEOUT second window before giving up.
Fixes bug 24894; bugfix on 0.3.2.1-alpha.

... in get_interface_addresses_ioctl().
This pointer alignment issue exists on x86_64 macOS, but is unlikely to exist
elsewhere. (i386 macOS only requires 4-byte alignment, and other OSs have
8-byte ints.)
Fixes bug 24733; not in any released version of tor.
Avoid selecting fallbacks that change their IP addresses too often.
Select more fallbacks by ignoring the Guard flag, and allowing lower
cutoffs for the Running and V2Dir flags. Also allow a lower bandwidth,
and a higher number of fallbacks per operator (5% of the list).
Implements ticket 24785.
Add the generateFallbackDirLine.py script for automatically generating
fallback directory mirror lines from relay fingerprints. No more typos!
Add the lookupFallbackDirContact.py script for automatically looking up
operator contact info from relay fingerprints.
Implements ticket 24706.
This removes some redundant repeated lines.
Ticket 24681 will maintain the current fallback weights by changing
Tor's default fallback weight to 10.
Implements ticket 24679.
These are all about local variables shadowing global
functions. That isn't normally a problem, but at least one
compiler we care about seems to treat this as a case of -Wshadow
violation, so let's fix it.
Fixes bug 24634; bugfix on 0.3.2.1-alpha.
Tor now sets IPv6 preferences on rewrite_node_address_for_bridge() even if
there is only ri or rs. It always warns about them.
Also Tor now sets the IPv6 address in rs as well as it sets the one in ri.

Tor test now checks if "ping -6 -c 1 -W 1 ::1" works when "ping6 -c 1 -W 1 ::1"

When the fascist_firewall_choose_address_ functions don't find a
reachable address, set the returned address to the null address and port.
This is a precautionary measure, because some callers do not check the
return value.
Fixes bug 24736; bugfix on 0.2.8.2-alpha.
This makes clients on the public tor network prefer to bootstrap off fallback
directory mirrors.
This is a follow-up to 24679, which removed weights from the default fallbacks.
Implements ticket 24681.
We've been seeing problems with destroy cells queues taking up a
huge amount of RAM. We can mitigate this, since while a full packed
destroy cell takes 514 bytes, we only need 5 bytes to remember a
circuit ID and a reason.
Fixes bug 24666. Bugfix on 0.2.5.1-alpha, when destroy cell queues
were introduced.
With extra_space negative, it means that the "notsent" queue is quite large so
we must consider that value with the current computed tcp_space. If we end up
to have negative space, we should not add more data to the kernel since the
notsent queue is just too filled up.

Instead of using INT_MAX as a write limit for KISTLite, use the lower layer
limit which is using the specialized num_cells_writeable() of the channel that
will down the line check the connection's outbuf and limit it to 32KB
(OR_CONN_HIGHWATER).
That way we don't take the chance of bloating the connection's outbuf and we
keep the cells in the circuit queue which our OOM handler can take care of,
not the outbuf.
Finally, this commit adds a log_debug() in the update socket information
function of KIST so we can get the socket information in debug.
