An unnecessary routerlist check in the NETINFO clock skew detection in
channel_tls_process_netinfo_cell() was preventing clients from
reporting NETINFO clock skew to controllers.
Make download status next attempts reported over the control port
consistent with the time used by tor. This issue only occurs if a
download status has not been reset before it is queried over the
control port.
Fixes 23525, not in any released version of tor.
If future code asks if there are any running bridges, without checking
if bridges are enabled, log a BUG warning rather than crashing.
Fixes 23524 on 0.3.0.1-alpha
Directory servers now include a "Date:" http header for response
codes other than 200. Clients starting with a skewed clock and a
recent consensus were getting "304 Not modified" responses from
directory authorities, so without a Date header the client would
never hear about a wrong clock.
Fixes bug 23499; bugfix on 0.0.8rc1.
This change refactors find_dl_schedule() to only call dependent functions
as needed. In particular, directory_fetches_from_authorities() only needs
to be called on clients.
Stopping spurious directory_fetches_from_authorities() calls on every
download on public relays has the following impacts:
* fewer address resolution attempts, particularly those mentioned in 21789
* fewer descriptor rebuilds
* fewer log messages, particularly those limited in 20610
Fixes 23470 in 0.2.8.1-alpha.
The original bug was introduced in commit 35bbf2e as part of prop210.
OpenBSD doesn't like tricks where you use a too-wide sscanf argument
for a too-narrow array, even when you know the input string
statically. The fix here is just to use bigger buffers.
Fixes 15582; bugfix on a3dafd3f58 in 0.2.6.2-alpha.
But when clients are just starting, make them try each bridge a few times
before giving up on it.
These changes make the bridge download schedules more explicit: before
17750, they relied on undocumented behaviour and specific schedule
entries. (And between 17750 and this fix, they were broken.)
Fixes 23347, not in any released version of tor.
The download schedule tells Tor to wait 15 minutes before downloading
bridge descriptors. But 17750 made Tor ignore that and start immediately.
Since we fixed 17750, Tor waits 15 minutes for bridge client bootstrap,
like the schedule says.
This fixes the download schedule to start immediately, and to try each
bridge 3 times in the first 30 seconds. This should make bridge bootstraps
more reliable.
Fixes 23347.
When option validation or transition is happening, there are no
"current options" -- only "old options" and "maybe new options".
Looking at get_options() is likely a mistake, so have a nonfatal
assertion let us know if we do that.
Closes 22281.
