Runtime spec says: > sysctl (object, OPTIONAL) allows kernel parameters to be modified at > runtime for the container. For more information, see the sysctl(8) > man page. and sysctl(8) says: > variable > The name of a key to read from. An example is > kernel.ostype. The '/' separator is also accepted in place of a '.'. Apparently, runc config validator do not support sysctls with / as a separator. Fortunately this is a one-line fix. Add some more test data where / is used as a separator. Signed-off-by: Kir Kolyshkin <kolyshkin@gmail.com>

In the unit test, the sysctl value with existing dots and slashes is also added.

I think there is a problem with your conversion:
If the ssyctl value is net/pv4/conf/eno2.100/rp_filter
The correct conversion result should be net.ipv4.conf.eno2/100.rp_filter
