A fair number of our mock_impl declarations were messed up so that

This should be a whitespace-only patch.

I think this one probably can't underflow, since the input ranges
are small. But let's not tempt fate.
This patch also replaces the "cmp" functions here with just "eq"
functions, since nothing actually checked for anything besides 0 and
nonzero.
Related to 21278.
This patch refactors duplicated code, to check if a given router
supports fetching the extra-info document, into a common macro called
SKIP_MISSING_TRUSTED_EXTRAINFO.
This patch generalizes the two functions
router_is_already_dir_fetching_rs and router_is_already_dir_fetching_ds
into a single function, router_is_already_dir_fetching_, by lifting the
passing of the IPv4 & IPv6 addresses and the directory port number to
the caller.
The microdesc consensus does not contain any IPv6 addresses.
When a client has a microdesc consensus but no microdescriptor, make it
use the hard-coded IPv6 address for the node (if available).
(Hard-coded addresses can come from authorities, fallback directories,
or configured bridges.)
If there is no hard-coded address, log a BUG message, and fail the
connection attempt. (All existing code checks for a hard-coded address
before choosing a node address.)
Fixes 20996, fix on b167e82 from 19608 in 0.2.8.5-alpha.
Back when Roger had do do most of our testing on the moria host, we
needed a higher limit for the number of relays running on a single
IP address when that limit was shared with an authority. Nowadays,
the idea is pretty obsolete.
Also remove the router_addr_is_trusted_dir() function, which served
no other purpose.
Closes ticket 20960.
The signed_descriptor_move() was not releasing memory inside the destination
object before overwriting it with the source object. This commit adds a reset
function that free that memory inside a signed descriptor object and zero it.
Closes#20715.

This patch doesn't cover every case; omitted cases are marked with
"XXXX prop271", as usual. It leaves both the old interface and the
new interface for guard status notification, since they don't
actually work in the same way: the new API wants to be told when a
circuit has failed or succeeded, whereas the old API wants to know
when a channel has failed or succeeded.
I ran into some trouble with directory guard stuff, since when we
pick the directory guard, we don't actually have a circuit to
associate it with. I solved that by allowing guard states to be
associated with directory connections, not just circuits.
This patch is just:
* Code movement
* Adding headers here and there as needed
* Adding a bridges_free_all() with a call to it.
It breaks compilation, since the bridge code needed to make exactly
2 calls into entrynodes.c internals. I'll fix those in the next
commit.
This affects clients with FetchUselessDescriptors 1.
It might also cause subtle bugs on directory mirrors and authorities,
causing them to consider all full descriptors as failed or old.

When we refactored purpose_needs_anonymity(), we made it so _all_
bridge requests required anonymity. But that missed the case
that we are allowed to ask a bridge for its own descriptor.
With this patch, we consider the resource, and allow "authority.z"
("your own descriptor, compressed") for a bridge's server descriptor
to be non-anonymous.

This commit adds or improves the module-level documenation for:

In particular, I've tried to explain (for each documented module)
what each module does, what's in it, what the big idea is, why it
belongs in Tor, and who calls it. In a few cases, I've added TODO
notes about refactoring opportunities.
I've also renamed an argument, and fixed a few DOCDOC comments.
(Technically, we could just remove extend2 cell checking entirely,
since all Tor versions on our network are required to have it, but
let's keep this around as an example of How To Do It.)
This bug had existed since 0.2.4.7-alpha, but now that we have
FallbackDirs by default, it actually matters.
Fixes bug 19947; bugfix on 0.2.4.7-alpha or maybe 0.2.8.1-alpha.
Rubiate wrote the patch; teor wrote the changes file.
If we know a node's version, and it can't do ntor, consider it not running.
If we have a node's descriptor, and it doesn't have a valid ntor key,
consider it not running.
Refactor these checks so they're consistent between authorities and clients.
Code has been changed so every RSA fingerprint for a commit in our state is
validated before being used. This fixes the unit tests by mocking one of the
key function and updating the hardcoded state string.

When you divide an int by an int and get a fraction and _then_ cast
to double, coverity assumes that you meant to cast to a double
first.
In my fix for -Wfloat-conversion in 493499a339, I
did something like this that coverity didn't like.
Instead, I'm taking another approach here.
Fixes CID 1232089, I hope.
Previously, we used !directory_fetches_from_authorities() to predict
that we would tunnel connections. But the rules have changed
somewhat over the course of 0.2.8
So, back long ago, XXX012 meant, "before Tor 0.1.2 is released, we
had better revisit this comment and fix it!"
But we have a huge pile of such comments accumulated for a large
number of released versions! Not cool.
So, here's what I tried to do:
* 0.2.9 and 0.2.8 are retained, since those are not yet released.
* XXX+ or XXX++ or XXX++++ or whatever means, "This one looks
quite important!"
* The others, after one-by-one examination, are downgraded to
plain old XXX. Which doesn't mean they aren't a problem -- just
that they cannot possibly be a release-blocking problem.
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.
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.
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.
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.
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.
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.
