When calling `circpad_send_padding_cell_for_callback()`, the flag
`is_padding_timer_scheduled` was not resetted to 0 which caused an issue
in the circpad simulator.
This commit fixes this problem.
Fixes#32671.
In brief: we go through a lot of gymnastics to handle huge protover
numbers, but after years of development we're not even close to 10
for any of our current versions. We also have a convenient
workaround available in case we ever run out of protocols: if (for
example) we someday need Link=64, we can just add Link2=0 or
something.
This patch is a minimal patch to change tor's behavior; it doesn't
take advantage of the new restrictions.
Implements #40133 and proposal 318.
This patch renames the enumeration value in `outbound_addr_t` from
`OUTBOUND_ADDR_EXIT_AND_OR` to `OUTBOUND_ADDR_ANY` since with the
arrival of `OUTBOUND_ADDR_PT` it no longer makes sense to call the
fallback value for "Exit and OR". Instead we rename it to "any".

We set this flag if we've launched the connection in order to
satisfy an origin circuit, or when we decide the connection _would_
satisfy an origin circuit. These are the only or_connections we
want to consider for bootstrapping: other or_connections are opened
because of client EXTEND requests, and they may succeed or fail
because of the clients' confusion or misconfiguration.
Closes#25061.
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.
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 used to have a single boolean, "FascistFirewall". Ages ago, in
tickets #17840 and #9067, we added an improved "ReachableAddresses"
mechanism. It's time to rename related identifiers in the code for
consistency. This closes#18106.

This function once served to let circuits continue to be built over
version-1 link connections. But such connections are long-obsolete,
and it's time to remove this check.
Closes#40081.
