When we close a connection via connection_close_immediately, we kill
its events immediately. But if it had been blocked on bandwidth
read/write, we could try to re-add its (nonexistent) events later
from connection_bucket_refill -- if we got to that callback before
we swept the marked connections.
Fixes bug 24167. Fortunately, this hasn't been a crash bug since we
introduced connection_check_event in 0.2.9.10, and backported it.
This is a bugfix on commit 89d422914a, I believe, which
appeared in Tor 0.1.0.1-rc.
evdns is allowed to give us unrecognized object types; it is allowed
to give us non-IPv4 answer types, and it is (even) allowed to give
us empty answers without an error.
Closes ticket 24097.
Due to #23662 this can happen under natural causes and does not disturb
the functionality of the service. This is a simple 0.3.2 fix for now,
and we plan to fix this properly in 0.3.3.
Clients add rendezvous point IPv6 addresses to introduce cell link specifiers,
when the node has a valid IPv6 address.
Also check the node's IPv4 address is valid before adding any link specifiers.
Implements #23577.
This function -- a mock replacement used only for fuzzing -- would
have a buffer overflow if it got an RSA key whose modulus was under
20 bytes long.
Fortunately, Tor itself does not appear to have a bug here.
Fixes bug 24247; bugfix on 0.3.0.3-alpha when fuzzing was
introduced. Found by OSS-Fuzz; this is OSS-Fuzz issue 4177.
On failure to upload, the HS_DESC event would report "UPLOAD_FAILED" as the
Action but it should have reported "FAILED" according to the spec.
Fixes#24230

DisableNetwork is a subset of net_is_disabled(), which is (now) a
subset of should_delay_dir_fetches().
Some of these changes are redundant with others higher or lower in
the call stack. The ones that I think are behavior-relevant are
listed in the changes file. I've also added comments in a few
places where the behavior is subtle.
Fixes bug 12062; bugfix on various versions.
