Fixes bug 20894; bugfix on 0.2.0.16-alpha.
We already applied a workaround for this as 20834, so no need to
freak out (unless you didn't apply 20384 yet).
According to 21116, it seems to be needed for Wheezy Raspbian build. Also,
manpage of socket(2) does confirm that this errno value should be catched as
well in case of no support from the OS of IPv4 or/and IPv6.
Fixes#21116

Check size argument to memwipe() for underflow.
Closes bug #18089. Reported by "gk", patch by "teor".
Bugfix on 0.2.3.25 and 0.2.4.6-alpha (#7352),
commit 49dd5ef3 on 7 Nov 2012.
The length of auth_data from an INTRODUCE2 cell is checked when the
auth_type is recognized (1 or 2), but not for any other non-zero
auth_type. Later, auth_data is assumed to have at least
REND_DESC_COOKIE_LEN bytes, leading to a client-triggered out of bounds
read.
Fixed by checking auth_len before comparing the descriptor cookie
against known clients.
Fixes#15823; bugfix on 0.2.1.6-alpha.
Bug 21242 occurred because we asserted that extend_info_from_node()
had succeeded...even though we already had the code to handle such a
failure. We fixed that in 93b39c5162.
But there were four other cases in our code where we called
extend_info_from_node() and either tor_assert()ed that it returned
non-NULL, or [in one case] silently assumed that it returned
non-NULL. That's not such a great idea. This patch makes those
cases check for a bug of this kind instead.
Fixes bug 21372; bugfix on 0.2.3.1-alpha when
extend_info_from_node() was introduced.
Once a second, we go over all services and consider the validity of the intro
points. Now, also try to remove expiring nodes that have no more circuit
associated to them. This is possible if we moved an intro point object
previously to that list and the circuit actually timed out or was closed by
the introduction point itself.

Previously the dirserv_orconn_tls_done() function would skip routers
when they advertised an ed25519 key but didn't present it during the
link handshake. But that covers all versions between 0.2.7.2-alpha
and 0.2.9.x inclusive!
Fixes bug 21107; bugfix on 0.3.0.1-alpha.
