d0e6abd087 Reset dormancy status when the clock jumps. 2018-11-15 11:17:22 -05:00

ce6209cee4 Add a periodic event to become dormant.
This event makes us become dormant if we have seen no activity in a
long time.

Note that being any kind of a server, or running an onion service,
always counts as being active.

Note that right now, just having an open stream that Tor
did not open on its own (for a directory request) counts as "being
active", so if you have an idle ssh connection, that will keep Tor
from becoming dormant.

Many of the features here should become configurable; I'd like
feedback on which.

2c15b65381 Make the NET_PARTICIPANT role dependent on user activity
This patch implements all of 28337, except for the part where we
turn off the role if we've been idle for a long time.

303e5c70e0 Move the responsibility for delayed shutdown into the mainloop
This is part of 28422, so we don't have to call
consider_hibernation() once per second when we're dormant.

This commit does not remove delayed shutdown from hibernate.c: it
uses it as a backup shutdown mechanism, in case the regular shutdown
timer mechanism fails for some reason.

(There was nothing else in second_elapsed_callbck() that couldn't go
here.)

b9a88bd53a Add new "ALL" and "NET_PARTICIPANT" roles for periodic events
The previous "ALL" role was the OR of a bunch of other roles,
which is a mistake: it's better if "ALL" means "all".

The "NET_PARTICIPANT" role refers to the anything that is actively
building circuits, downloading directory information, and
participating in the Tor network.  For now, it is set to
!net_is_disabled(), but we're going to use it to implement a new
"extra dormant mode".

Closes ticket 28336.

c99f220f78 conn: Close the read side of a closing connection when write limit is reached
In conn_close_if_marked(), we can decide to keep a connection open that still
has data to flush on the wire if it is being rate limited on the write side.

However, in this process, we were also looking at the read() side which can
still have token in its bucket and thus not stop the reading. This lead to a
BUG() introduced in 0.3.4.1-alpha that was expecting the read side to be
closed due to the rate limit but which only applies on the write side.

This commit removes any bandwidth check on the read side and simply stop the
read side on the connection regardless of the bucket state. If we keep the
connection open to flush it out before close, we should not read anything.

Fixes #27750
