While doing some performance tracing of an application with the FreeBSD hwpmc subsystem as a normal user in a jail, I tripped over a kernel crash (this only happens if INVARIANTS is compiled into the kernel, so not with a RELEASE kernel).

Recently I added some changes to FreeBSD (src and ports) which allow enabling some compiler features when building FreeBSD or 3rd party programs.

In May I committed a new feature to FreeBSD-current (it will be in the FreeBSD 15 release, I have no plans to merge this to 14).

If you haven’t read part 1 already, please do so.

What this is about I stumbled upon the work of Bojan Novković regarding physical memory anti-fragmentation mechanisms (attention, this is a link to the FreeBSD wiki, content may change without further notice).

Problem If you setup a system, you want to make sure that it complies to a pre-defined config.

Problem You have a LDOM which you want to clone to somewhere else and all you have to perform that is the ldm command on the target system.

Problem There may be a folder (with broken inheritance) with files / directories where you want to make sure that there is no specific group / item included.

This is not about how to generate a self-signed certificate, this is about how to configure an ldap client to connect securely to a ldap server which has a self-signed certificate.
