Single onion services and Tor2web deliberately create long-term one-hop
circuits to their intro and rend points, respectively.
These log messages are intended to diagnose issue 8387, which relates to
circuits hanging around forever for no reason.
Fixes bug 20613; bugfix on 0.2.9.1-alpha. Reported by "pastly".
Because as Teor puts it: "[Resetting on 503] is exactly what we
don't want when relays are busy - imagine clients doing an automatic
reset every time they DoS a relay..."
Fixes bug 20593.
It's only safe to remove the failure limit (per 20536) if we are in
fact waiting a bit longer each time we try to download.
Fixes bug 20534; bugfix on 0.2.9.1-alpha.
If a consensus expires while we are waiting for certificates to download,
stop waiting for certificates.
If we stop waiting for certificates less than a minute after we started
downloading them, do not consider the certificate download failure a
separate failure.
Fixes bug 20533; bugfix on commit e0204f21 in 0.2.0.9-alpha.
Relays do not deliberately launch multiple attempts, so the impact of this
bug should be minimal. This fix also defends against bugs like #20499.
Bugfix on 0.2.8.1-alpha.
Fixes bug 19969; bugfix on b1d56fc58. We can fix this some more in
later Tors, but for now, this is probably the simplest fix possible.
This is a belt-and-suspenders fix, where the earlier fix ("Ask
event_base_loop to finish when we add a pending stream") aims to respond
to new streams as soon as they arrive, and this one aims to make sure
that we definitely respond to all of the streams.
ome policies are default-reject, some default-accept. But
policy_is_reject_star() assumed they were all default_reject. Fix
that!
Also, document that policy_is_reject_star() treats a NULL policy as
empty. This allows us to simplify the checks in
parse_reachable_addresses() by quite a bit.
Fxes bug 20306; bugfix on 0.2.8.2-alpha.
(Also, refactor the code to create a hidden service directory into a
separate funcion, so we don't have to duplicate it.)
Fixes bug 20484; bugfix on 0.2.9.3-alpha.
This simplifies the function: if we have an ntor key, use ntor/EXTEND2,
otherwise, use TAP/EXTEND.
Bugfix on commit 10aa913 from 19163 in 0.2.9.3-alpha.
The tor_fragile_assert() bug has existed here since c8a5e2d588
in tor-0.2.1.7-alpha forever, but tor_fragile_assert() was mostly a
no-op until 0.2.9.1-alpha.
Fixes bug 19869.
This helps protect against bugs where any part of a buf_t's memory
is passed to a function that expects a NUL-terminated input.
It also closes TROVE-2016-10-001 (aka bug 20384).
This commit adds or improves the module-level documenation for:
buffers.c circuitstats.c command.c connection_edge.c control.c
cpuworker.c crypto_curve25519.c crypto_curve25519.h
crypto_ed25519.c crypto_format.c dircollate.c dirserv.c dns.c
dns_structs.h fp_pair.c geoip.c hibernate.c keypin.c ntmain.c
onion.c onion_fast.c onion_ntor.c onion_tap.c periodic.c
protover.c protover.h reasons.c rephist.c replaycache.c
routerlist.c routerparse.c routerset.c statefile.c status.c
tor_main.c workqueue.c
In particular, I've tried to explain (for each documented module)
what each module does, what's in it, what the big idea is, why it
belongs in Tor, and who calls it. In a few cases, I've added TODO
notes about refactoring opportunities.
I've also renamed an argument, and fixed a few DOCDOC comments.
