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.
When we refactored purpose_needs_anonymity(), we made it so _all_
bridge requests required anonymity. But that missed the case
that we are allowed to ask a bridge for its own descriptor.
With this patch, we consider the resource, and allow "authority.z"
("your own descriptor, compressed") for a bridge's server descriptor
to be non-anonymous.
Fix for bug 20410; bug not in any released Tor.
I believe that this should never trigger, but if it does, it
suggests that there was a gap between is_sensitive_dir_purpose and
purpose_needs_anonymity that we need to fill. Related to 20077.
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.
(I've done this instead of changing the semantics of
router_compare_to_my_exit_policy, because dns.c uses
router_compare_to_my_exit_policy too, in a slightly weird way.)
