This patch changes the slow process_t tests to use
run_main_loop_until_done() instead of do_main_loop() since
do_main_loop() initializes a lot of subsystem callbacks that we don't
need to run in our tests.
See: https://bugs.torproject.org/28179
This patch makes the managed proxy subsystem use the process_t data
structure such that we can get events from the PT process while Tor is
running and not just when the PT process is being configured.
See: https://bugs.torproject.org/28179
The old implementation did some funky out-of-order lexing, and
tended to parse every port twice if the %d-%d pattern didn't match.
Closes ticket 28853.
When the clock jumps, and we have a record of last user activity,
adjust that record. This way if I'm inactive for 10 minutes and
then the laptop is sleeping for an hour, I'll still count as having
been inactive for 10 minutes.
Previously, we treat every jump as if it were activity, which is
ridiculous, and would prevent a Tor instance with a jumpy clock from
ever going dormant.
Rather than initializing the "Dormant" status to "off" and the "last
activity" count to "now", initialize them based on our state file:
stay dormant if we were dormant, or remember the amount of time
we've spent inactive.
The DormantClientTimeout option controls how long Tor will wait before
going dormant. It also provides a way to disable the feature by setting
DormantClientTimeout to e.g. "50 years".
The DormantTimeoutDisabledByIdleStreams option controls whether open but
inactive streams count as "client activity". To implement it, I had to
make it so that reading or writing on a client stream *always* counts as
activity.
Closes ticket 28429.
Specifically, if the consensus is older than the (estimted or
measured) release date for this version of tor, we assume that the
required versions may have changed in between that consensus and
this release.
Implements ticket 27735 and proposal 297.
After we clear the protover map for getting full, we need to
re-create it, since we are about to use it.
This is a bugfix for bug 28558. It is a bugfix for the code from
ticket 27225, which is not in any released Tor. Found by Google
OSS-Fuzz, as issue 11475.
This representation is meant to save memory in microdescriptors --
we can't use it in routerinfo_t yet, since those families need to be
encoded losslessly for directory voting to work.
This representation saves memory in three ways:
1. It uses only one allocation per family. (The old way used a
smartlist (2 allocs) plus one strdup per entry.)
2. It stores identity digests in binary, not hex.
3. It keeps families in a canonical format, memoizes, and
reference-counts them.
Part of #27359.
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.
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.
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.
