#24000: circuit_send_intermediate_onion_skin() and extend_cell_format() should
check for IPv6

Reporter: teor | Owner: (none)
Type: defect | Status: new
Priority: Medium | Milestone: Tor: 0.3.3.x-final
Component: Core Tor/Tor | Version:
Severity: Normal | Keywords: ipv6

------------------------------+--------------------------------
When circuit_send_intermediate_onion_skin() and extend_cell_format()
handle tor_addr_t, they assume they are IPv4.
But in #23502, we almost wrote code that sent them an IPv6 address. In
this case, they put 0.0.0.0 in the extend cell, but they could issue a
BUG() warning and refuse to send the cell instead.
Or they could send a proper IPv6 link specifier where the extend cell
allows it.
