The "once" flag makes tor_bug_occurred_() say that future instances
of the warning will be suppressed -- but that's not something that
BUG() does. Fixes bug 33095; bugfix on 0.4.1.1-alpha.
When we added the ACTIVE and DORMANT virtual signals, we taught the
signal command to handle them, but we didn't teach SIGNAL event to
report them.
To solve this problem and prevent it from recurring, this patch
revises the implementation of control_event_signal() to use the same
signal_table that handle_control_signal() uses. This way, the two
controller commands can't become out of sync.
Fixes bug 33104; bugfix on 0.4.0.1-alpha.
Fixes bug 32673; bugfix on 0.3.0.4-alpha. We introduced these
checks in ee5471f9aa to help diagnose 21369, but we used "-1"
when "TOR_TLS_ERROR_MISC" would have been correct. Found by opara.
I don't think that this is actually getting triggered in the wild,
but if it were, it could cause nasty behavior: spurious
WANTREAD/WANTWRITE returns have a way of turning into CPU-eating
busy-loops.
We introduced these BUG() checks in b0ddaac074 to prevent a
recurrence of bug 23690. But there's a report of the BUG() message
getting triggered and filling up the disk. Let's change it to
IF_BUG_ONCE().
Fixes bug 33093; bugfix on 0.3.2.2-alpha.
Simplify ip_address_changed() by removing redundant checks
(all exits are relays, and need to rebuild their descriptor when their
IP addresses change).
Rewrite the function comment, and rename the argument, so the function
is easier to understand and use.
Closes 33091.
Stop allowing failures on the Travis CI stem tests job. It looks like
all the stem hangs we were seeing are now fixed, but let's make sure we
see them if they happen again.
Closes ticket 33075.
Explain that:
* most flags default to off
* flags that default to on are specified
Document PreferIPv6Automap in its "No" form, because it's on by
default.
Cleanup after 32637.
Make Tor clients tell dual-stack exits that they prefer IPv6
connections.
This change is equivalent to setting the PreferIPv6 flag on
SOCKSPorts (and most other listener ports). Tor Browser has
been setting this flag for some time, and we want to remove a
client distinguisher at exits.
Also update the man page, putting all the IP flags in their
non-default forms.
Closes ticket 32637.
