Hey,

What is required for testing the wccp code?


At minimum a Router or Switch with WCCPv2, plus separate machines for client and proxy.

Ideally;
* at least two router/switch to test the changed code handling multiple routers.
 * ability to test both Mask and GRE assignment methods.
 * ability to test a mix of the capability and security settings in WCCPv2.


I can try to get a Cisco device for a basic testing.
Is there a specific bug report we can follow on this issue or maybe we should follow on the PR?


Test results in the PR please.

Cheers
Amos

Does anyone understand what is causing these errors? Are there any
known issues or patches in progress?

A few years ago, several serious problems were discovered in WCCP code,
including security vulnerabilities:

https://github.com/squid-cache/squid/security/advisories/GHSA-rgf3-9v3p-qp82

Some of the WCCP bugs were fixed without testing; developers fixing
those bugs could not easily test WCCP. Some of the old WCCP bugs
remained and some of the new fixes were buggy.

Today, WCCP code remains problematic. If your customers rely on WCCP,
consider investing into revamping that neglected and buggy feature.


This PR <https://github.com/squid-cache/squid/pull/970> has some
progress towards a fix of those. See the latest comment (currently Sept
2022) for issues that still need to be resolved before that PR is ready
for merge attempt.

The major issue remains the ability to test.
