pf TSO patch fallout - squid (and potentially other) issues
0%
Description
With commit:c57f939b20a6a7a66351ce973843ce7d8564ed72 ( https://rcs.pfsense.org/projects/pfsense-tools/repos/mainline/commits/c57f939b20a6a7a66351ce973843ce7d8564ed72 ) in the tools repo a patch was added to improve the behavior of TSO.
At the very least this patch has broken squid's transparent redirect, and potentially other things.
On a snapshot from today, you can install squid, turn on transparent mode and the redirect tries to happen but just hangs. I built a custom update with just that one patch reverted and it works fine with squid and transparent mode.
I hesitate to just revert the patch in the repo in case it can be easily fixed.

Same issue here.
Performed an auto update today. Installed squid. Normal proxy works ok, transparent does not. From what i can see with tcpdump my machine does get the responses but the checksums are incorrect:

I disabled the patch and have a new snapshot building now. The next new snapshot dated after this update should be OK.
