It is usually beneficial to set IKE SA, IKE Child SA, and Configuration Backend to logging level "Diag" when troubleshooting IPsec issues. Propose changing these to be the default settings with all others staying at level "Control."

Any attempts on tweaks useful for debugging here are completely useless while IPsec log is being flooding with tons of utter junk.

100+ lines of the above shit in 5 minutes. At default logging levels. Awesome. I certainly object to increasing loglevels of anything here until the crap it muted.

  • Target version set to 2.4.0

Those are a different story entirely and unrelated to this at all. See #4227 (If you set "Networking" and "Message Encoding" to audit or silent it may be able to stop those from being logged)

The log areas in question on this ticket are what we always recommend for IPsec troubleshooting anyhow, it only increases the log verboseness during negotiation and it shows much more useful information about the encryption/authentication/traffic selector exchanges.
