The optimization of sysctlbyname() in commit d05b53e0baee7 had the side-effect of not going through the fix-up for the user.* variables in the previously called sysctl() function. This lead to 0 or an empty strings being returned by sysctlbyname() for all user.* variables. An alternate implementation would store the user variables in the kernel during system start-up. That would allow to remove the fix-up code in the C library that is currently required to provide the actual values. This update restores the previous code path for the user.* variables and keeps the performance optimization intact for all other variables.

FreeBSD Source:
This is the top level of the FreeBSD source directory.
FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
