Patch to add sync conn timeout systcl
Created attachment 363510 [details]
backport of whats upstream
not sure why you would use a new sysctl to do this. From my read upstream sets up a table of sysctls to do this in a more fine grained manner. This is a backport of of whats upstream right now. I'll submit a brew build soon for it. Can you please try this with the customer and see how it works out. Thanks!

corrected patch
sorry, corrected patch. The sysctl values in proc should actually not be there, as they're deprecated (or were never actually used). By drawing timeouts from the timeout_table that enables you to use the ipvsadm utility with the --set option to set the timeouts your interested in. I'll post a build url shortly. Please test and confirm that it does what you need it to do. Thanks!

grr. This is what I get for trying to build in brew straight away. Some more corrected errors. If this build fails, I'll debug it locally over the weekend.

oi, I've built it locally, and this patch will build in brew.
