We need this field to be in signed_descriptor_t so that
routerinfo_incompatible_with_extrainfo can work correctly (#17150).
But I don't want to move it completely in this patch, since a great
deal of the code that messes with it has been in flux since 0.2.7,
when this ticket was opened. I should open another ticket about
removing the field from routerinfo_t and extrainfo_t later on.
This patch fixes no actual behavior.
The routerinfo we pass to routerinfo_incompatible_with_extrainfo is
the latest routerinfo for the relay. The signed_descriptor_t, on
the other hand, is the signed_descriptor_t that corresponds to the
extrainfo. That means we should be checking the digest256 match
with that signed_descriptor_t, not with the routerinfo.
Fixes bug 17150 (and 19017); bugfix on 0.2.7.2-alpha.
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Fixes bug 11454, where we would keep around a superseded descriptor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.
