Hi all, Please review the devel^2 ~ devel^5 (inclusive) at: http://gitweb.dragonflybsd.org/~sephe/dragonfly.git/shortlog/refs/heads/devel
The modification/accessing to the udbinfo is protected by two mechanism: 1) netisr barrier, which prevents code running in netisr from accessing udbinfo when the modification is going to happen 2) serializer, which prevents code not running in netisr (e.g. sysctl, interface detaching) from accessing udbinfo when the modification is going to happen 1) makes the udp input/output path lock free. Best Regards, sephe -- Tomorrow Will Never Die
