Disabling CONFIG_RT_SCHED_GROUP to mitigate potential memory management (MM) issues, including increased memory pressure, fragmentation, and memory leaks that can arise from real-time scheduling.
CONFIG_NETFILTER_XT_TARGET_TRACE is a Linux kernel configuration option that enables the xt_trace module in the Netfilter framework. The xt_trace module is used to trace the passage of packets through firewall filtering rules, allowing network administrators to identify the sequence of rules that each packet passes through.
However, it is recommended to disable this option in most production cases. There are a few reasons for this:
1. Performance: Enabling packet tracking can result in significant system overhead as it requires each packet to be logged and tracked by all firewall rules.
2. Security: Packet tracking can provide detailed information about firewall behavior and which rules are being used. This can be exploited by an attacker to gain information about the network topology and plan more effective attacks.
3. Limited usefulness: In production environments, the usefulness of package tracking may be limited. Typically, it is more important to ensure that firewall rules are configured correctly and to ensure that security policies are applied correctly rather than individually tracking each packet.
Because of these reasons, the CONFIG_NETFILTER_XT_TARGET_TRACE configuration option is often recommended to be disabled in production environments. It is important to carefully evaluate the need for package tracking before enabling it in a production environment.
