SNMP V3 Pdu request size not handled

[Alessandro BESSI]

In net-snmp 5.8, a regression has been done with SNMP v3 and the maximum size for the session.
It's corrected in 5.9 and was working in 5.7.
I have tested the change and all is working fine.
Please see https://github.com/net-snmp/net-snmp/commit/78bf0069ddd24ea0cc716421c53e1daf46da7002

Is there a way to integrate it in the 5.8 release ?

Description: Ubuntu 20.04.1 LTS
Release: 20.04

Hi Alessandro and thanks for this bug report. This is the kind of fix that can be backported to existing stable releases using the SRU process [1]. Given that every change comes with a regression risk, the most important ingredient of a SRU is the broken use case that the proposed upgrade fixes, see [3]. This is missing in both this bug report and in the upstream commit [3] message you pointed us to (thanks!).

Could you please provide more information about the problem that [3] fixes, describing the broken use case? Steps to reproduce the broken scenario are normally the best explanation.

Waiting for your reply I'm marking this bug report as Incomplete.
