FreeBSD 13 and W^X memory mapping policy for user processes
FreeBSD 13.0-RELEASE is out, and one of the new features is W^X memory mapping policy for user processes. This feature is also naturally available for users of 13.0-STABLE and 14.0-CURRENT.

After upgrading a test VM to 14.0-CURRENT this week, I was greeted with a large Terminus font.

The bootloader in recent stable/11 always gave me trouble booting the kernel due to having loader_color=”YES” in my /boot/loader.conf. Strangely enough, the same setting is harmless in recent stable/12.

iperf3 results between Chelsio T6225-CR and Intel X710-DA4
I ran two iperf3 tests between two hosts using Chelsio T6225-CR and Intel X710-DA4, respectively. Both NICs are connected to the supervisor interfaces on a Sup8E in a Cisco Catalyst 4500E chassis. Wirespeed is 10 Gbit/s.

After upgrading this system to stable/12 r348672, my Chelsio T6225-CR NIC finally provided acceptable performance.

Citrix Hypervisor 8.0.0 and FreeBSD guests running with UEFI boot firmware
I installed Citrix XenServer 7.2 on a spare server, created a small VM running FreeBSD/amd64 head r347896, and updated the host all the way to XS 7.6. Upgrading to Citrix Hypervisor 8.0.0 requires boot media, and the procedure is pretty painless. I added the XS80E001.zip update and rebooted the host. Neither a license server nor a license […]

I upgraded base from 12.0-ALPHA9 to 13.0-CURRENT (r339639) on a VM today. While preparing for rebuilding localbase, I wiped clean /var/synth/live_packages/{All,Latest}/*, and cleaned the ccache repo stored in /var/cache/ccache. Trouble arose when I ordered ports-mgmt/synth to rebuild some 116 ports according to a specification stored in a local metaport. DEFAULT_VERSION+=ssl=base was being used at the […]

First attempt at running FreeBSD/amd64 12.0-BETA1
I spent the better part of the weekend upgrading my laptop to 12.0-BETA1. Three hickups has been discovered so far.

After upgrading to stable/11, r339418, incorporating the recent commits for cxgbe(4) et al. (r339389, and r339393-r339404), I see a somewhat improved iperf3 performance.
