Since "skip orport check" is the "and" of v4_ok and v6_ok, we can
just compute v4_ok and v6_ok once, to clarify that we don't enter
this block of code if they're both true.
I've managed to keep this change mainly contained to our
self-testing module. The changes here are:
* There are two different variables for tracking "is our orport
reachable".
* We have a new function that says whether we can skip a single
family's orport reachability test; the old function for this now
tells whether we can skip _all_ orport reachability testing.
(The name, router_should_skip_orport_reachability_test, is not
so good. I will rename it later if I can think of a good
replacement.)
* The function that launches orport reachability tests now only
launches the ones that haven't completed.
* The function that notes that we're reachable on an ORPort now
takes a family.
* Various log messages are cleaned up.
This tracking of the instantiation count should eliminate race conditions due
to starting and stopping machines rapidly. Now, we should no longer obey
STOP commands for previous machines.
This field area was memset to 0 in old versions, which the code treats as
"match any machine instance", for backward compatibility without a protover
bump.
Per ticket #32888 this should address logging "the Address torrc
option", "and whether it is an IP address, or a DNS name"; or the
detected "local hostname", "and whether it is an IP address, or a DNS
name". Some of these details already seem to be logged, so just add
what's missing.
Resume being willing to use preemptively-built circuits when
UseEntryGuards is set to 0. We accidentally disabled this feature with
that config setting (in our fix for #24469), leading to slower load times.
Fixes bug 34303; bugfix on 0.3.3.2-alpha.
The warning was:
11:23:10 ../tor/src/feature/hs/hs_service.c: In function 'log_cant_upload_desc':
11:23:10 ../tor/src/feature/hs/hs_service.c:3118:3: error: comparison of unsigned expression < 0 is always false [-Werror=type-limits]
See #34254 for more info.
I guess this means that gcc assigned an unsigned type to the
`log_desc_upload_reason_t` enum and it warned if we compared it against 0...
For now I think it's simpler to remove that check instead of turning the enum
to a signed type, or trying to hack it some other way.
From what it seems, enum is up to the compiler on whether it's signed/unsigned:

Use the node check function to check that there are enough nodes to
select a circuit path.
Adds these checks, which are implied by other code:
* supports EXTEND2 cells,
* does not allow single-hop exits,
Adds these extra checks:
* has a general-purpose routerinfo,
* if it is a direct connection, check reachable addresses.
These checks reduce the node count, but they will never under-count
nodes.
Bridge nodes aren't handled correctly, we'll fix that in the next
commit.
Part of 34200.
And check that the correct flags are passed when choosing exits.
Adds the following checks for exits:
* must support EXTEND2 cells,
* must have an ntor circuit crypto key,
* can't require the guard flag,
* can't be a direct connection.
All these checks are already implied by other code.
Part of 34200.
