This is meant for use when encrypting the current time within the
period in order to get a monotonically increasing revision counter
without actually revealing our view of the time.
This scheme is far from the most state-of-the-art: don't use it for
anything else without careful analysis by somebody much smarter than
I am.
See ticket #25552 for some rationale for this logic.
If an authority is not configured with a V3BandwidthsFile, this line
SHOULD NOT appear in its vote.
If an authority is configured with a V3BandwidthsFile, but parsing
fails, this line SHOULD appear in its vote, but without any headers.
Part of 3723, implements the spec in 26799.
also add tests for bw_file_headers.
Headers are all that is found before a correct relay line or
the terminator.
Tests include:
* a empty bandwidth file
* a bandwidth file with only timestamp
* a bandwidth file with v1.0.0 headers
* a bandwidth file with v1.0.0 headers and relay lines
* a bandwidth file with v1.1.0 headers and v1.0.0 relay lines
* a bandwidth file with v1.0.0 headers, malformed relay lines and
relay lines
* a bandwidth file with v1.0.0 headers, malformed relay lines,
relay lines and malformed relay lines
* a bandwidth file with v1.1.0 headers without terminator
* a bandwidth file with v1.1.0 headers with terminator
* a bandwidth file with v1.1.0 headers without terminator and
relay lines
* a bandwidth file with v1.1.0 headers with terminator and relay
lines
* a bandwidth file with v1.1.0 headers without terminator, bad
relay lines and relay lines
* a bandwidth file with v1.1.0 headers with terminator, bad relay
lines and relay lines
If bandwidth file terminator is found, set end of headers flag
and do not store the line.
If it is not, parse a relay line and check whether it is a header
line.
* add bwlist_headers argument to dirserv_read_measured_bandwidth
in order to store all the headers found when parsing the file
* add bwlist_headers to networkstatus_t in order to store the
the headers found by the previous function
* include the bandwidth headers as string in vote documents
* add test to check that dirserv_read_measured_bandwidth generates
the bwlist_headers
Coverity rightly complains that early in the function we're checking
whether username is NULL, and later we're passing it unconditionally
to strlen().
Fixes CID 1437967. Bug not in any released Tor.
This patch adds two assertions in get_net_param_from_list() to ensure
that the `res` value is correctly within the range of the output domain.
Hopefully fixes Coverity CID #1415721, #1415722, and #1415723.

The "Bifroest" bridge authority has been retired; the new bridge authority
is "Serge", and it is operated by George from the TorBSD project.
Closes ticket 26771.
