Bug 1: We were purporting to calculate milliseconds per tick, when we
*should* have been computing ticks per millisecond.
Bug 2: Instead of computing either one of those, we were _actually_
computing femtoseconds per tick.
These two bugs covered for one another on x86 hardware, where 1 tick
== 1 nanosecond. But on M1 OSX, 1 tick is about 41 nanoseconds,
causing surprising results.
Fixes bug 40684; bugfix on 0.3.3.1-alpha.
Patch to address #40673. An additional check has been added to
onion_pending_add() in order to ensure that we avoid counting create
cells from clients.
In the cpuworker.c assign_onionskin_to_cpuworker
method if total_pending_tasks >= max_pending_tasks
and channel_is_client(circ->p_chan) returns false then
rep_hist_note_circuit_handshake_dropped() will be called and
rep_hist_note_circuit_handshake_assigned() will not be called. This
causes relays to run into errors due to the fact that the number of
dropped packets exceeds the total number of assigned packets.
To avoid this situation a check has been added to
onion_pending_add() to ensure that these erroneous calls to
rep_hist_note_circuit_handshake_dropped() are not made.
See the #40673 ticket for the conversation with armadev about this issue.
We need to tune these, but we're not likely to need the subtle differences
between a few of them. Removing them will prevent our consensus parameter
string from becoming too long in the event of tuning.
mike is concerned that we would get too much exposure to adversaries,
if we enforce that none of our L2 guards can be in the same family.
this change set now essentially finishes the feature that commit a77727cdc
was attempting to add, but strips the "_and_family" part of that plan.
We had omitted some checks for whether our vanguards (second layer
guards from proposal 333) overlapped or came from the same family.
Now make sure to pick each of them to be independent.
Fixes bug 40639; bugfix on 0.4.7.1-alpha.
