This also moves the warnings and add some theatrical effect around the
code so anyone modifying those list should notice the warnings signs and
read the comment accordingly.

Doing this in the wrong way has potential to cause serious havoc on
the network, so let's make it harder for future programmers to mess
it up.

Our code doesn't allow it and so this prevents an assert() crash if the
DirPort is for instance IPv6 only.
Fixes #40494

Closes #40504

This patch fixes the current build of main on Windows.
|
|
|
|
|
|
|
|
While trying to resolve our CI issues, the Windows build broke with an
unused function error:
src/test/test_switch_id.c:37:1: error: ‘unprivileged_port_range_start’
defined but not used [-Werror=unused-function]
We solve this by moving the `#if !defined(_WIN32)` test above the
`unprivileged_port_range_start()` function defintion such that it is
included in its body.
This is an unreviewed commit.
See: tor#40275

When we don't yet have a descriptor for one of our bridges, disable
the entry guard retry schedule on that bridge. The entry guard retry
schedule and the bridge descriptor retry schedule can conflict,
e.g. where we mark a bridge as "maybe up" yet we don't try to fetch
its descriptor yet, leading Tor to wait (refusing to do anything)
until it becomes time to fetch the descriptor.
Fixes bug 40497; bugfix on 0.3.0.3-alpha.

we do a notice-level log when we decide we *don't* have enough dir
info, but in 0.3.5.1-alpha (see commit eee62e13d97, #14950) we lost our
corresponding notice-level log when things come back.
bugfix on 0.3.5.1-alpha; fixes bug 40496.
|
|
Specifically, every time a guard moves into or out of state
GUARD_REACHABLE_MAYBE, it is an opportunity for the guard reachability
state to get out of sync with the have-minimum-dir-info state.
Fixes even more of #40396.
|
|
When we try to fetch a bridge descriptor and we fail, we mark
the guard as failed, but we never scheduled a re-compute for
router_have_minimum_dir_info().
So if we had already decided we needed to wait for this new descriptor,
we would just wait forever -- even if, counterintuitively, *losing* the
bridge is just what we need to *resume* using the network, if we had it
in state GUARD_REACHABLE_MAYBE and we were stalling to learn this outcome.
See bug 40396 for more details.

The bridge descriptor fetching codes ends up fetching a lot of duplicate
bridge descriptors, because this is how we learn when the descriptor
changes.
This commit only changes comments plus whether we log that one line.
It moves us back to the old behavior, before the previous commit for
30496, where we would only log that line when the bridge descriptor
we're talking about is better than the one we already had (if any).
