In dirserv_compute_performance_thresholds, we allocate arrays based
on the length of 'routers', a list of routerinfo_t, but loop over
the nodelist. The 'routers' list may be shorter when relays were
filtered by routers_make_ed_keys_unique, leading to an out-of-bounds
write on directory authorities.
This bug was originally introduced in 26e89742, but it doesn't look
possible to trigger until routers_make_ed_keys_unique was introduced
in 13a31e72.
Fixes bug 19032; bugfix on tor 0.2.8.2-alpha.
This makes our compilation options checks in autoconf work better on
systems that already define _FORTIFY_SOURCE.
Fixes at least one case of bug 18841; bugfix on 0.2.3.17-beta. Patch
from "trudokal".
Previously, we were using the generic schedule for some downloads,
and the consensus schedule for others.
Resolves ticket 18816; fix on fddb814fe in 0.2.4.13-alpha.
This improves client anonymity and avoids directory header tampering.
The extra load on the authorities should be offset by the fallback
directories feature.
This also simplifies the fixes to #18809.
Delete an unnecessary check for non-preferred IP versions.
Allows clients which can't reach any directories of their
preferred IP address version to get directory documents.
Patch on #17840 in 0.2.8.1-alpha.
After #17840 in 0.2.8.1-alpha, we incorrectly chose an IPv4
address for all DIRIND_ONEHOP directory connections,
even if the routerstatus didn't have an IPv4 address.
This likely affected bridge clients with IPv6 bridges.
Resolves#18921.
The problem is that "q" is always set on the first iteration even
if the question is not a supported question. This set of "q" is
not necessary, and will be handled after exiting the loop if there
if a supported q->type was found.

* SHA-3/SHAKE use little endian for certain things, so byteswap as
needed.
* The code was written under the assumption that unaligned access to
quadwords is allowed, which isn't true particularly on non-Intel.
As well as the existing reports of IPv6 address additions or removals,
the script now warns when keys change but IPv4:ORPort or
IPv6:IPv6ORPort remain the same.
Existing checks for other whitelist detail changes have also
been re-worded and upgraded to warnings.
This makes it easier for changes to be identified so operators can
be contacted to confirm whether the change is stable.
Also, put libor-testing.a at a better position in the list of
libraries, to avoid linker errors.
This is a fix, or part of a fix, for 18490.

This changes simply renames them by removing "Testing" in front of them and
they do not require TestingTorNetwork to be enabled anymore.

Yes, we could cast to unsigned char first, but it's probably safest
to just use our own (in test_util), or remove bad-idea features that
we don't use (in readpassphrase.c).
Fixes 18728.
Only when we were actually flushing the cell stats to a controller
would we free them. Thus, they could stay in RAM even after the
circuit was freed (eg if we didn't have any controllers).
Fixes bug 18673; bugfix on 0.2.5.1-alpha.
We added these a while ago, but they do no actual good, and
cause implicit declaration warnings in some situations. Rather than
just adding stdint.h, it's easier to remove the exit() calls
as redundant.
Fixes bug 18626; bugfix from "cypherpunks"
Regardless of the setting of ExtendAllowPrivateAddresses.
This fixes a bug with pluggable transports that ignore the
(potentially private) address in their bridge line.
Fixes bug 18517; bugfix on 23b088907f in tor-0.2.8.1-alpha.
When requesting extrainfo descriptors from a trusted directory
server, check whether it is an authority or a fallback directory
which supports extrainfo descriptors.
Fixes bug 18489; bugfix on 90f6071d8d in tor-0.2.4.7-alpha.

Downgrade logs and backtraces about IP versions to
info-level. Only log backtraces once each time tor runs.

I had a half-built mechanism to track, during the voting process,
whether the Ed25519 value (or lack thereof) reflected a true
consensus among the authorities. But we never actually inserted this
field in the consensus.
The key idea here is that we first attempt to match up votes by pairs
of <Ed,RSA>, where <Ed> can be NULL if we're told that there is no
Ed key. If this succeeds, then we can treat all those votes as 'a
consensus for Ed'. And we can include all other votes with a
matching RSA key and no statement about Ed keys as being "also about
the same relay."
After that, we look for RSA keys we haven't actually found an entry
for yet, and see if there are enough votes for them, NOT considering
Ed keys. If there are, we match them as before, but we treat them
as "not a consensus about ed".
When we include an entry in a consensus, if it does not reflect a
consensus about ed keys, then we include a new NoEdConsensus flag on
it.
This is all only for consensus method 22 or later.
Also see corresponding dir-spec patch.
When generating a vote, and we have two routerinfos with the same ed
key, omit the one published earlier.
This was supposed to have been solved by key pinning, but when I
made key pinning optional, I didn't realize that this would jump up
and bite us. It is part of bug 18318, and the root cause of 17668.
If we're a server with no address configured, resolve_my_hostname
will need this. But not otherwise. And the preseeding itself can
consume a few seconds if like tails we have no resolvers.
Fixes bug 18548.
Launching 7 descriptor fetches makes a connection to each HSDir that is 6
and the seventh one fails to pick an HSDir because they are all being used
already so it was killing all pending connections at once.
