58276715be Fix support for HTTP proxies (#11245)
* Disable incorrect check for hidden services in Socket

Hidden services can only be accessed with an HTTP proxy, in which
case the host seen by the Socket class will be the proxy, not the
target host.

Avoid the timeout logic being bypassed

* Add support for IP addresses in Request::Socket

* Refactor a bit, no need to keep the DNS resolver around

Fix connect timeout not being enforced (#9329)
* Fix connect timeout not being enforced

The loop was catching the timeout exception that should stop execution, so the next IP would no longer be within a timed block, which led to requests taking much longer than 10 seconds.

* Use timeout on each IP attempt, but limit to 2 attempts

* Fix code style issue

* Do not break Request#perform if no block given

* Update method stub in spec for Request

* Move timeout inside the begin/rescue block

* Use Resolv::DNS with timeout of 1 to get IP addresses

* Update Request spec to stub Resolv::DNS instead of Addrinfo

* Fix Resolve::DNS stubs in Request spec

Improve support for aspects/circles (#8950)
* Add silent column to mentions

* Save silent mentions in ActivityPub Create handler and optimize it

Move networking calls out of the database transaction

* Add "limited" visibility level masked as "private" in the API

Unlike DMs, limited statuses are pushed into home feeds. The access
control rules between direct and limited statuses is almost the same,
except for counter and conversation logic

* Ensure silent column is non-null, add spec

* Ensure filters don't check silent mentions for blocks/mutes

As those are "this person is also allowed to see" rather than "this
person is involved", therefore does not warrant filtering

* Clean up code

* Use Status#active_mentions to limit returned mentions

* Fix code style issues

* Use Status#active_mentions in Notification

And remove stream_entry eager-loading from Notification

Improve signature verification safeguards (#8959)
* Downcase signed_headers string before building the signed string

The HTTP Signatures draft does not mandate the “headers” field to be downcased,
but mandates the header field names to be downcased in the signed string, which
means that prior to this patch, Mastodon could fail to process signatures from
some compliant clients. It also means that it would not actually check the
Digest of non-compliant clients that wouldn't use a lowercased Digest field
name.

Thankfully, I don't know of any such client.

* Revert "Remove dead code (#8919)"

This reverts commit a00ce8c92c.

* Restore time window checking, change it to 12 hours

By checking the Date header, we can prevent replaying old vulnerable
signatures. The focus is to prevent replaying old vulnerable requests
from software that has been fixed in the meantime, so a somewhat long
window should be fine and accounts for timezone misconfiguration.

* Escape users' URLs when formatting them

Fixes possible HTML injection

* Escape all string interpolations in Formatter class

Slightly improve performance by reducing class allocations
from repeated Formatter#encode calls

* Fix code style issues

Move network calls out of transaction in ActivityPub handler (#8951)
Mention and emoji code may perform network calls, but does not need
to do that inside the database transaction. This may improve availability
of database connections when using pgBouncer in transaction mode.
