I did not check all the details, but it looks like Squid ICMP code
(ab)uses StoreEntry-linked metadata. Basic CONNECT tunnels lack
StoreEntry because they are not reading/writing data from/to Store. The
combination is essentially a Squid bug -- basic CONNECT tunnels cannot
use ICMP features.
CONNECT tunnel should be able to use data from ICMP like other code
doing peer selection.
I see several bugs here:
1) ICMP relying on StoreEntry as a data source. The server (if not a
cache_peer) being ping'ed should come from the CONNECT request object URI.
2) peer selection initiating ICMP directly. It should be retrieving
RTT values from NetDB, which indirectly uses ICMP to get updates.
