Some functions that use digest maps did not mention that the digests are
expected to have DIGEST_LEN bytes. This lead to buffer over-reads in the
past.
Mark fallback directory mirrors as "too busy" when they return
a 503 response. Previously, the code just marked authorities as busy.
Unless clients set their own fallback directories, they will never see
this bug. (There are no default fallbacks yet.)
Fixes bug 17572; bugfix on 5c51b3f1f0 released in 0.2.4.7-alpha.
Patch by "teor".
Instead of having it call update_all_descriptor_downloads and
update_networkstatus_downloads directly, we can have it cause them to
get rescheduled and called from run_scheduled_events.
Closes ticket 16789.
Extrainfo documents are now ed-signed just as are router
descriptors, according to proposal 220. This patch also includes
some more tests for successful/failing parsing, and fixes a crash
bug in ed25519 descriptor parsing.
Routers now use TAP and ntor onion keys to sign their identity keys,
and put these signatures in their descriptors. That allows other
parties to be confident that the onion keys are indeed controlled by
the router that generated the descriptor.
Fixes bug 11454, where we would keep around a superseded descriptor
if the descriptor replacing it wasn't at least a week later. Bugfix
on 0.2.1.8-alpha.
Fixes bug 11457, where a certificate with a publication time in the
future could make us discard existing (and subsequent!) certificates
with correct publication times. Bugfix on 0.2.0.3-alpha.
Decrease minimum consensus interval to 10 seconds
when TestingTorNetwork is set. (Or 5 seconds for
the first consensus.)
Fix code that assumes larger interval values.
This assists in quickly bootstrapping a testing
Tor network.
Fixes bugs 13718 & 13823.
Instead, generate new keys, and overwrite the empty key files.
Adds FN_EMPTY to file_status_t and file_status.
Fixes bug 13111.
Related changes due to review of FN_FILE usage:
Stop generating a fresh .old RSA key file when the .old file is missing.
Avoid overwriting .old key files with empty key files.
Skip loading zero-length extra info store, router store, stats, state,
and key files.
We were only using it when smartlist_choose_node_by_bandwidth_weights
failed. But that function could only fail in the presence of
buggy/ancient authorities or in the absence of a consensus. Either
way, it's better to use sensible defaults and a nicer algorithm.
