1. DNS lookups fail completely. 204.127.198.4 is among a handful of
external DNS servers I use, whether defined as dns_nameservers in
squid.conf or picked by squid automatically from /etc/resolv.conf:

Is IPv6 dual-stack enabled in your OS? it looks like the v6 sockets are
unable to do the v4-mapping they need to handle v4 traffic.
I find it a bit weird that setting TOS also fails, its one of the older
functionality and shared between both IP protocols.
I'd think so. I'm using 6to4, if that matters. Here's the snippet from
config.log:t

Here's cache.log with debug_options 0,5 78,9:

2. Does that above have anything to do with the failure to apply this
patch?
patch -p0 < b9691.patch
patching file src/dnsserver.cc
Hunk #1 FAILED at 427.
Hunk #2 FAILED at 436.
2 out of 2 hunks FAILED -- saving rejects to file src/dnsserver.cc.rej
I hope not. That patch does not alter anything functionally and is
internal to the obsolete dnsserver helper.
3. I see the following in cache.log. I realize they're warnings, but is
there any way to make squid "happy"? I thought the slash format is a
CIDR
mask.
WARNING: Netmasks are deprecated. Please use CIDR masks instead.
WARNING: IPv4 netmasks are particularly nasty when used to compare IPv6
to
IPv4 ranges.
squid.conf:
acl sitelocalsrc src fec0::/48
acl linklocalsrc src fe80::/64
The conf is correct, if the warnings are appearing on that line something
has definitely broken.
Tomorrow is my actually scheduled day for squid maintenance. I will have
to look at these closer after the maintenance work.

Turns out my previous conjecture was wrong. Those warnings appear even after
I've commented out all the IPv6 bits in the ACLs. Here' the complete lines from
cache.log, in case it matters:
2009/05/20 23:46:02| WARNING: Netmasks are deprecated. Please use CIDR masks
instead.

Sorry I didn't get to this a few days ago.
Are you using the default squid.conf that gets built with 3.1 or an
altered version?
Problem #3 will show up for some settings even though there is not yet
any other way to do them than netmasks. So it needs to be looked at but
in some cases can be ignored.
Problem #1, I'm still thinking about.
