When we merged the cookieauthfile creation logic in 33c3e60a37, we
accidentally took out this feature. Fixes bug 12864, bugfix on
0.2.5.1-alpha.
Also adds an ExtORPortCookieAuthFileGroupReadable, since there's no
reason not to.
We added some AS_VAR_IF-based checks to detect whether we have
managed to compile (but not link) with stack-protector. On autoconf
before 2.63, we don't have AS_VAR_IF, so we just have to let the
user get a compile error rather than a helpful "find libssp" error.
Fixes bug 12693; bugfix on 0.2.5.2-alpha (commit 21ac292820)
Coccinelle is a semantic patching tool that can automatically change
C code via semantic patching.
This script also replaces realloc with reallocarray as appropriate.
I looked for other places where we set circ->n_chan early, and found
one in circuit_handle_first_hop() right before it calls
circuit_send_next_onion_skin(). If onion_skin_create() fails there,
then n_chan will still be set when circuit_send_next_onion_skin()
returns. We should probably fix that too.
When Tor starts with DisabledNetwork set, it would correctly
conclude that it shouldn't try making circuits, but it would
mistakenly cache this conclusion and continue believing it even
when DisableNetwork is set to 0. Fixes the bug introduced by the
fix for bug 11200; bugfix on 0.2.5.4-alpha.
Our current systemd unit uses "Type = simple", so systemd does not expect tor to
fork. If the user has "RunAsDaemon 1" in their torrc, then things won't work as
expected. This is e.g. the case on Debian (and derivatives), since there we pass
"--defaults-torrc /usr/share/tor/tor-service-defaults-torrc" (that contains
"RunAsDaemon 1") by default.
The only solution I could find is to explicitly pass "--RunAsDaemon 0" when
starting tor from the systemd unit file, which this commit does.
Those used to be normal to receive on hidden service circuits due to bug
1038, but the buggy Tor versions are long gone from the network so we
can afford to resume watching for them. Resolves the rest of bug 1038;
bugfix on 0.2.1.19.
Roger spotted this on tor-dev in his comments on proposal 221.
(Actually, detect DESTROY vs everything else, since arma likes
network timeout indicating failure but not overload indicating failure.)
