26146dbe9e Comment-out fallbacks in a way the stem fallback parser understands
If we manually remove fallbacks in C by adding '/*' and '*/' on separate
lines, stem still parses them as being present, because it only looks at
the start of a line.

Add a comment to this effect in the generated source code.

Remove a fallback that changed IPv4 address

Remove two fallbacks that were slow to deliver consensuses,
we can't guarantee they'll be fast in future.

Blacklist all these fallbacks until operators confirm they're stable.

bdc59e33c1 Fix a warning on unnamed nodes in node_get_by_nickname().
There was a > that should have been an ==, and a missing !.  These
together prevented us from issuing a warning in the case that a
nickname matched an Unnamed node only.

Fixes bug 19203; bugfix on 0.2.3.1-alpha.

9cf6af76eb Fix a double-free bug in routerlist_reparse_old
I introduced this bug when I moved signing_key_cert into
signed_descriptor_t. Bug not in any released Tor.  Fixes bug 19175, and
another case of 19128.

Just like signed_descriptor_from_routerinfo(), routerlist_reparse_old()
copies the fields from one signed_descriptor_t to another, and then
clears the fields from the original that would have been double-freed by
freeing the original.  But when I fixed the s_d_f_r() bug [#19128] in
50cbf22099, I missed the fact that the code was duplicated in
r_p_o().

Duplicated code strikes again!

For a longer-term solution here, I am not only adding the missing fix to
r_p_o(): I am also extracting the duplicated code into a new function.

Many thanks to toralf for patiently sending me stack traces until
one made sense.

50cbf22099 Fix a bug related to moving signing_key_cert
Now that the field exists in signed_descriptor_t, we need to make
sure we free it when we free a signed_descriptor_t, and we need to
make sure that we don't free it when we convert a routerinfo_t to a
signed_descriptor_t.

But not in any released Tor. I found this while working on #19128.

One problem: I don't see how this could cause 19128.

ab932cd7bf Remove duplicate siging_key_cert fields.
With the fix for #17150, I added a duplicate certificate here.  Here
I remove the original location in 0.2.8.  (I wouldn't want to do
that in 027, due to the amount of authority-voting-related code
drift.)

Closes 19073.

00f74e0372 Improve API of routerinfo_incompatible_with_extrainfo()
This API change makes it so that routerinfo_incompatible...() no
longer takes a routerinfo_t, so that it's obvious that it should
only look at fields from the signed_descriptor_t.

This change should prevent a recurrence of #17150.

8acfac7375 Copy the signing_key_cert field into signed_descriptor_t
We need this field to be in signed_descriptor_t so that
routerinfo_incompatible_with_extrainfo can work correctly (#17150).
But I don't want to move it completely in this patch, since a great
deal of the code that messes with it has been in flux since 0.2.7,
when this ticket was opened.  I should open another ticket about
removing the field from routerinfo_t and extrainfo_t later on.

This patch fixes no actual behavior.

7d1eb0d570 When making sure digest256 matches in ei, look at sd, not ri.
The routerinfo we pass to routerinfo_incompatible_with_extrainfo is
the latest routerinfo for the relay.  The signed_descriptor_t, on
the other hand, is the signed_descriptor_t that corresponds to the
extrainfo.  That means we should be checking the digest256 match
with that signed_descriptor_t, not with the routerinfo.

Fixes bug 17150 (and 19017); bugfix on 0.2.7.2-alpha.

bf3e32a452 Fix out-of-bounds write during voting with duplicate ed25519 keys
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.
