01733e2b15 New AuthDirPinKeys option to enable/disable keypinning enforcement
Implements ticket #17135.  We're going to need this one to avoid
chaos as everybody figures out how ed25519 keys work.

c5e87e33c7 Allow conflicts to occur in keypinning journal
When we find a conflict in the keypinning journal, treat the new
entry as superseding all old entries that overlap either of its
keys.

Also add a (not-yet-used) configuration option to disable keypinning
enforcement.

098b82c7b2 ExitPolicyRejectPrivate rejects local IPv6 address and interface addresses
ExitPolicyRejectPrivate now rejects more local addresses by default:
 * the relay's published IPv6 address (if any), and
 * any publicly routable IPv4 or IPv6 addresses on any local interfaces.

This resolves a security issue for IPv6 Exits and multihomed Exits that
trust connections originating from localhost.

d3358a0a05 ExitPolicy accept6/reject6 produces IPv6 wildcard addresses only
In previous versions of Tor, ExitPolicy accept6/reject6 * produced
policy entries for IPv4 and IPv6 wildcard addresses.

To reduce operator confusion, change accept6/reject6 * to only produce
an IPv6 wildcard address.

Resolves bug #16069.

e033d5e90b Ignore accept6/reject6 IPv4, warn about unexpected rule outcomes
When parsing torrc ExitPolicies, we now warn if:
  * an IPv4 address is used on an accept6 or reject6 line. The line is
    ignored, but the rest of the policy items in the list are used.
    (accept/reject continue to allow both IPv4 and IPv6 addresses in torrcs.)
  * a "private" address alias is used on an accept6 or reject6 line.
    The line filters both IPv4 and IPv6 private addresses, disregarding
    the 6 in accept6/reject6.

When parsing torrc ExitPolicies, we now issue an info-level message:
  * when expanding an accept/reject * line to include both IPv4 and IPv6
    wildcard addresses.

In each instance, usage advice is provided to avoid the message.

8b98172579 Add a rend cache failure info dup function
When validating a new descriptor against our rend cache failure, we were
added the failure entry to the new cache entry without duplicating. It was
then freed just after the validation ending up in a very bad memory state
that was making tor abort(). To fix this, a dup function has been added and
used just before adding the failure entry.

Fixes #17041

f6c446db47 Check NoKeepAliveIsolateSOCKSAuth in a better place.
No functional changes, but since NoKeepAliveIsolateSOCKSAuth isn't
part of isoflag, it should be checked where all other similar options
are, and bypass the (no-op) masking at the end.

07b3028db7 Prohibit the use of one entry node with an HS
In a nutshell, since a circuit can not exit at its entry point, it's very
easy for an attacker to find the hidden service guard if only one EntryNodes
is specified since for that guard, the HS will refuse to build a rendezvous
circuit to it.

For now, the best solution is to stop tor to allow a single EntryNodes for
an hidden service.
