This patch disables the glob() support in the path library if glob() is
unavailable at build-time. This currently happens with the Android NDK
used for Tor Browser.
See: https://bugs.torproject.org/tpo/core/tor/40114
tl;dr We were not counting cells flying from the client to the service, but we
were counting cells flying from the service to the client.
When a rendezvous cell arrives from the client to the RP, the RP forwards it to
the service.
For this to happen, the cell first passes through command_process_relay_cell()
which normally does the statistics counting. However because the `rend_circ`
circuit was not flagged with `circuit_carries_hs_traffic_stats` in
rend_mid_rendezvous(), the cell is not counted there.
Then the cell goes to circuit_receive_relay_cell() which has a special code
block based on `rend_splice` specifically for rendezvous cells, and the cell
gets directly passed to `rend_circ` via a direct call to
circuit_receive_relay_cell(). The cell never passes through
command_process_relay_cell() ever again and hence is never counted by our
rephist module.
The fix here is to flag the `rend_circ` circuit with
`circuit_carries_hs_traffic_stats` so that the cell is counted as soon as it
hits command_process_relay_cell().
Furthermore we avoid double-counting cells since the special code block of
circuit_receive_relay_cell() makes us count rendezvous cells only as they enter
the RP and not as they exit it.
Fixes#40117.
When accessing the last_resolved_address cache we always need to convert the
AF family value to an index value else we are out of bound and thus
overflowing if we write to it.
This fix is on code that has not been released.

Opening a new listener connection can fail in many ways like a bind()
permission denied on a low port for instance.
And thus, we should expect to handle an error when creating a new one instead
of assert() on it.
To hit the removed assert:
ORPort 80
KeepBindCapabilities 0
Start tor. Then edit torrc:
ORPort <some-IP>:80
HUP tor and the assert is hit.

Previously, we would treat *any* incoming circuit on a non-local
channel as meaning that our ORPort was reachable. With this patch,
we make sure that the address that the peer _says_ we have is the
same as the one we're trying to advertise right now.
Closes 20165. Bugfix on 4f5192b280 in 0.1.0.1-rc, when
reachability self-tests were first introduced.
Instead of looking at the "Address" option alone, instead check if we have an
address in our cache (that is discovered by tor). If not, then it tells us
that tor does not have an address to work with so we can then ask a directory
authority for a suggestion.

Turns out that the HS DoS defenses parameters were overwritten by the
consensus parameters everytime a new consensus would arrive.
This means that a service operator can still enable the defenses but as soon
as the intro point relay would get a new consensus, they would be overwritten.
And at this commit, the network is entirely disabling DoS defenses.
Fix this by introducing an "explicit" flag that indicate if the
ESTABLISH_INTRO cell DoS extension set those parameters or not. If set, avoid
using the consenus at once.
We are not bumping the protover HSIntro value for this because 0.4.2.x series
is EOL in 1 month and thus 0.4.3.x would be the only series with this bug. We
are confident that a backport and then upgrade path to the latest 0.4.4.x
stable coming up soon is enough to mitigate this problem in the coming months.
It avoids the upgrade path on the service side by keeping the requirement for
protover HSIntro=5.

We found this in #40076, after we started using buf_move_all() in

I know, the crash only affects master, but I think this warrants a

Fix crash introduced in #40020. On startup, tor calls
check_private_dir on the data and key directories. This function

should be for open instead of opendir, despite the fact that they
are directories.

Previously we tolerated up to 1.5 connections for every relay we

Fixes bug 33880, which seems to have been provoked by our #17592
change in 0.3.5.
In routerconf_find_ipv6_or_ap(), we check if the returned ORPort is internal
but not for listening. This means that IPv6 [::] is considered internal.
Thus, we can't use it, we have to look directly at the configured address and
port and if they are valid, we do consider that we have a valid IPv6 ORPort
and that we can thus extend in IPv6.

Now that tor automatically binds to IPv4 _and_ IPv6, in order to avoid
breaking configurations, we sanitize the parsed lists for duplicate ORPorts.
It is possible to happen because we still allow this configuration;
ORPort 9888
ORPort [4242::1]:9888
Meaning that the first ORPort value will bind to 0.0.0.0:9888 _and_ [::]:9888
which would lead to an error when attempting to bind on [4242::1]:9888.
However, that configuration is accepted today and thus we must not break it.
To remedy, we now sanitize the parsed list and prioritize an ORPort that has
an explicit address over the global one.
A warning is emitted if such configuration pattern is found. This is only for
the ORPort.

This commit makes it that if the ORPort is set with a single port, it will
bind to both global listen IPv4 and IPv6 addresses.
To pin an "ORPort <PORT>" to be IPv4 or IPv6, the IPv4Only/IPv6Only flags are
honored thus this will _only_ bind on IPv6 for that port value:
ORPort 9050 IPv6Only
Results in: [::]:9050
ORPort 9051 IPv4Only
Results in: [0.0.0.0]:9051
Attempting to configure an explicit IPv4 address with IPv6Only flag is an
error and vice versa.

Tor periodic events have moved to a role base model where relays have specific
events. One of those is to rebuild the descriptor and that is ran every
minute.
This removes the call to router_rebuild_descriptor() from
router_get_my_routerinfo_with_err() because that is the only code path that
can call for a rebuild every second.
Instead, when we mark the descriptor as dirty, immediately reschedule the
descriptor check periodic event so it can be rebuilt that way instead of
randomly when router_get_my_routerinfo_with_err() is called.

Commit b14b1f2b1d was a mistake.
In case an Address statement is missing for the wanted family but another one
exists for another family, simply continue the address discovery.
It is not a mistake to be missing an Address statement for a family because
the address could simply be discovered by the next methods. Not all address
family requires a specific Address statement.
However, we do bail if we couldn't find any valid address for the requested
family _and_ a resolve failed meaning we had a hostname but couldn't resolve
it. In that case, we can't know if that hostname would have been for v4 or v6
thus we can't continue the address discovery properly.

Only log the 'real_addr' when it is set to something.
Only log the ID when it is set.
When scrubbing the address, don't include a canonical address.
(There should never be a canonical address for a connection with no
ID set.)
Now that we've clarified that these functions only need to describe
the peer in a human-readable way, we can have them delegate to
connection_describe_peer().
This mode was only used in one place, and it caused a dangerous
mingling of functionality. The method is supposed to _describe_ the
peer's address, not give its actual address. We already had a
function to get the actual address.
* We no longer call this an optional method
* We document that it returns the real address, not a canonical one.
* We have it try harder if the real address hasn't been set yet.

See: https://bugs.torproject.org/tpo/core/tor/33781
Pass the IPv4 before the IPv6 like all our other interfaces.
Changes unreleased code related to #40043.
Closes#40045

This changes a LOT of code but in the end, behavior is the same.
Unfortunately, many functions had to be changed to accomodate but in majority
of cases, to become simpler.
Functions are also removed specifically those that were there to convert an
IPv4 as a host format to a tor_addr_t. Those are not needed anymore.
The IPv4 address field has been standardized to "ipv4_addr", the ORPort to
"ipv4_orport" (currently IPv6 uses ipv6_orport) and DirPort to "ipv4_dirport".
This is related to Sponsor 55 work that adds IPv6 support for relays and this
work is needed in order to have a common interface between IPv4 and IPv6.
Closes#40043.

These fields have a complicated history, some slightly complicated
behavior, and some definitely inadequate documentation. Before we
go fixing them up, let's document how they work now.
Fix on unreleased code.
Logical || in the BUG() made it that it would always trigger the BUG().

Fix on unreleased code.
The relay_new_address_suggestion() is called when a NETINFO cell is received
thus not only for relay or bridges.
Remove the BUG() that made sure only in server mode we could handle the
suggested address.
