This check makes it so we can reach "done" without setting "conn",
and so the "if (conn)" check will not be redundant, and so coverity
won't complain. Fixes CID 1422205. Not actually a bug.
There are three changes here:
* We need to allow epoll_pwait.
* We need to allow PF_NETLINK sockets to be opened with SOCK_CLOEXEC.
* We need to use openat() instead of open().
Note that this fix is not complete, since the openat() change is
turned off. The next commit will make the openat() change happen
when we're running glibc 2.26 or later.
Fix for 24315.
We don't want to allow general signals to be sent, but there's no
problem sending a kill(0) to probe whether a process is there.
Fixes bug 24198; bugfix on 0.2.5.1-alpha when the seccomp2 sandbox
was introduced.
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.
Commit 56c5e282a7 suppressed that same log
statement in directory_info_has_arrived() for microdescriptors so do the same
for the descriptors. As the commit says, we already have the bootstrap
progress for this.
Fixes#23861

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.
