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.

In Python 3.12, these invalid escape sequences emit SyntaxWarnings, and will
emit SyntaxErrors in a future release.
Found using: grep '[^r]["'\''].*\\[^rn\\x0t"]' $(grep -rl '^#!.*python')
We strongly suspect that bug 40897 was caused by a custom Tor client that
tried to use more than the default number of conflux circuits, for either
performance or traffic analysis defense gains, or both.
This entity hit a safety check on the exit side, which caused a UAF. Our
"belt and suspenders" snapped off, and hit us in the face... again...
Since there are good reasons to try more than 2 conflux legs, and research has
found some traffic analysis benefits with as many as 5, we're going to raise
and parameterize this limit as a form of bug bounty for finding this UAF, so
that this entity can try out a little more confluxing.
This should also make it easier for researchers to try things like gathering
traces with larger amounts of confluxing than normal, to measure real-world
traffic analysis impacts of conflux.
Shine on, you yoloing anonymous diamond. Let us know if you find out anything
interesting!
