Commit Message

Matthias Fischer Dec. 14, 2018, 4:40 a.m. UTC
  For details see:
http://www.squid-cache.org/Versions/v4/changesets/

In July 2018, 'squid 4' was "released for production use", see:
https://wiki.squid-cache.org/Squid-4

"The features have been set and large code changes are reserved for later versions."

I've tested almost all 4.x-versions and patch series before with good results.
Right now, 4.4 is running here with no seen problems together with
'squidclamav', 'squidguard' and 'privoxy'.

I too would declare this version stable.

Best,
Matthias

-    Certificate fields injection via %D in ERR_SECURE_CONNECT_FAIL (#306)
-    
-    %ssl_subject, %ssl_ca_name, and %ssl_cn values were not properly escaped when %D code was expanded in HTML context of the ERR_SECURE_CONNECT_FAIL template. This bug affects all
-    ERR_SECURE_CONNECT_FAIL page templates containing %D, including the default template.
-    
-    Other error pages are not vulnerable because Squid does not populate %D with certificate details in other contexts (yet).
-    
-    Thanks to Nikolas Lohmann [eBlocker] for identifying the problem.
-    
-    TODO: If those certificate details become needed for ACL checks or other non-HTML purposes, make their HTML-escaping conditional.
-    
-    This is a Measurement Factory project.

+    Fix netdb exchange with a TLS cache_peer (#307)
+    
+    Squid uses http-scheme URLs when sending netdb exchange (and possibly
+    other) requests to a cache_peer. If a DIRECT path is selected for that
+    cache_peer URL, then Squid sends a clear text HTTP request to that
+    cache_peer. If that cache_peer expects a TLS connection, it will reject
+    that request (with, e.g., error:transaction-end-before-headers),
+    resulting in an HTTP 503 or 504 netdb fetch error.
+    
+    Workaround this by adding an internalRemoteUri() parameter to indicate
+    whether https or http URL scheme should be used. Netdb fetches from
+    CachePeer::secure peers now get an https scheme and, hence, a TLS
+    connection.

+    Logging client "handshake" bytes is useful in at least two contexts:
+    
+    * Runtime traffic bypass and bumping/splicing decisions. Identifying
+      popular clients like Skype for Business (that uses a TLS handshake but
+      then may not speak TLS) is critical for handling their traffic
+      correctly. Squid does not have enough ACLs to interrogate most TLS
+      handshake aspects. Adding more ACLs may still be a good idea, but
+      initial sketches for SfB handshakes showed rather complex
+      ACLs/configurations, _and_ no reasonable ACLs would be able to handle
+      non-TLS handshakes. An external ACL receiving the handshake is in a
+      much better position to analyze/fingerprint it according to custom
+      admin needs.
+    
+    * A logged handshake can be used to analyze new/unusual traffic or even
+      trigger security-related alarms.
+    
+    The current support is limited to cases where Squid was saving handshake
+    for other reasons. With enough demand, this initial support can be
+    extended to all protocols and port configurations.
+    
+    This is a Measurement Factory project.

++		>handshake Raw client handshake
++			Initial client bytes received by Squid on a newly
++			accepted TCP connection or inside a just established
++			CONNECT tunnel. Squid stops accumulating handshake
++			bytes as soon as the handshake parser succeeds or
++			fails (determining whether the client is using the
++			expected protocol).
++
++			For HTTP clients, the handshake is the request line.
++			For TLS clients, the handshake consists of all TLS
++			records up to and including the TLS record that
++			contains the last byte of the first ClientHello
++			message. For clients using an unsupported protocol,
++			this field contains the bytes received by Squid at the
++			time of the handshake parsing failure.
++
++			See the on_unsupported_protocol directive for more
++			information on Squid handshake traffic expectations.
++
++			Current support is limited to these contexts:
++			- http_port connections, but only when the
++			  on_unsupported_protocol directive is in use.
++			- https_port connections (and CONNECT tunnels) that
++			  are subject to the ssl_bump peek or stare action.
++
++			To protect binary handshake data, this field is always
++			base64-encoded (RFC 4648 Section 4). If logformat
++			field encoding is configured, that encoding is applied
++			on top of base64. Otherwise, the computed base64 value
++			is recorded as is.
