I noticed this when doing some M4 macro analysis work, and saw
that the version of `ax_check_compile_flag.m4` in Tor has two serial
lines ('serial 5' and 'serial 6') which is invalid.
We could just fix one of the lines, but it makes more sense to just
sync with upstream, I think.
Import ax_check_compile_flag.m4 from autoconf-archive at latest
commit at time of writing (4e8aab846b0872fba99f1fe02ebcdff178a34c87).

It turns out that circuit_package_relay_cell() returns 0 in order to drop a
cell but there is a code path, if the circuit queue is full, that also silently
closes the circuit and returns 0.
This lead to Conflux thinking a cell was sent but actually the cell was not and
the circuit was closed leading to the hard assert.
And so this function makes sure that circuit_package_relay_cell() and
append_cell_to_circuit_queue() returns a value that indicate what happened with
the cell and circuit so the caller can make an informed decision with it.
This change makes it that we do NOT enter the Conflux subsystem if the cell is
not queued on the circuit.

This was previously added to facilitate testing intro point rotation
with chutney. However, the implementation is problematic since it forces
excessive rotation whenever TestingTorNetwork is enabled, and can't be
adjusted or disabled.
Alternatives for testing intro point rotation include:
* Using shadow to "fast forward" time
* Overriding the consensus parameters hs_intro_min_lifetime and
hs_intro_max_lifetime.
Fixes#40922
This check was originally added in 962765a3, with the intent of
preventing relays with 0 measured bandwidth from being listed in the
consensus (part of fixing #13000).
Currently, that decision and other relevant places effectively use
`dirserv_get_credible_bandwidth_kb`, which prefers bwauth-measured
bandwidth over the self-reported `bandwidthcapacity`, making this check
mostly redundant.
i.e. this change should only affect behavior when the relay has uploaded
a descriptor with `bandwidthcapacity=0` *and* we have a non-zero
measured bandwidth, in which case we'll still trust the measured
bandwidth. This is what we want when bootstrapping a network (e.g. for
testing), since it allows us to initialize bandwidths using a bandwidth
authority file.
A relay can still cause `router_is_active` to return false by setting
the hibernate flag.
Also see discussion in #40917.
Fixes#40917.
the sz_out param is set to what was read (i.e not including the final
NULL the function adds for convenience), but could be understood to
be set to what was read+1 (including the NULL terminator)
The only way to figure out that posting a vote or signatures to another
dirauth failed is by counting how many success messages there are on
notice level, and noticing that it is fewer than the number of
configured dirauths.
Closes#40910.
Allow "node_id" KeyValue without the dollar sign at the start of the
hexdigit in the BandwidthFiles, in order to easier database queries
combining Tor documents in which the relays fingerprint doesn't
include it.
Bugfix on all supported versions of Tor.
Closes#40891
This commit adds the total number of DROP cell seen, the total number of
DESTROY cell received and the total number of protocol violation that lead to a
circuit close.
