Sometimes when we call exit(), it's because the process is
completely hopeless: openssl has a broken AES-CTR implementation, or
the clock is in the 1960s, or something like that.
But sometimes, we should return cleanly from tor_main() instead, so
that embedders can keep embedding us and start another Tor process.
I've gone through all the exit() and _exit() calls to annotate them
with "exit ok" or "XXXX bad exit" -- the next step will be to fix
the bad exit()s.
First step towards 23848.
Version 3 hidden service needs rendezvous point that have the protocol version
HSRend >= 2 else the rendezvous cells are rejected.

This change should improve overhead for downloading small numbers of
descriptors and microdescriptors by improving compression
performance and lowering directory request overhead.
Closes ticket 23220.

A fair number of our mock_impl declarations were messed up so that
even our special AM_ETAGSFLAGS couldn't find them.
This should be a whitespace-only patch.
Deprecated in 0.2.9.2-alpha, this commits changes it as OBSOLETE() and cleans
up the code associated with it.

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.
Fix for bug 20410; bug not in any released Tor.
