Make directory authorities write the v3-status-votes file out
to disk earlier in the consensus process, so we have the votes
even if we abort the consensus process later on.
Resolves ticket 19036.
The goal here is to provide a way to decouple pieces of the code
that want to learn "when something happens" from those that realize
that it has happened.
The implementation here consists of a generic backend, plus a set of
macros to define and implement a set of type-safe frontends.
In dirserv_compute_performance_thresholds, we allocate arrays based
on the length of 'routers', a list of routerinfo_t, but loop over
the nodelist. The 'routers' list may be shorter when relays were
filtered by routers_make_ed_keys_unique, leading to an out-of-bounds
write on directory authorities.
This bug was originally introduced in 26e89742, but it doesn't look
possible to trigger until routers_make_ed_keys_unique was introduced
in 13a31e72.
Fixes bug 19032; bugfix on tor 0.2.8.2-alpha.
This makes our compilation options checks in autoconf work better on
systems that already define _FORTIFY_SOURCE.
Fixes at least one case of bug 18841; bugfix on 0.2.3.17-beta. Patch
from "trudokal".
This was one of our longest functions, at 600 lines. It makes a nice
table-driven URL-based function instead.
The code is a bit ugly, it leave the indentation as it is in hopes of
making pending directory.c changes easier to merge. Later we can
clean up the indentation.
Also, remove unused mallinfo export code from directory.c
Closes ticket 16698
Previously, we were using the generic schedule for some downloads,
and the consensus schedule for others.
Resolves ticket 18816; fix on fddb814fe in 0.2.4.13-alpha.
We used to be locked in to the "tap" handshake length, and now we can
handle better handshakes like "ntor".
Resolves ticket 18998.
I checked that relay_send_command_from_edge() behaves fine when you
hand it a payload with length 0. Clients behave fine too, since current
clients remain strict about the required length in the rendezvous2 cells.
(Clients will want to become less strict once they have an alternate
format that they're willing to receive.)
