Revision 7237f7e8f652392d9edca6b6c3f788b9aaa05ef9 authored by Bjoern A. Zeeb on 24 January 2010, 14:05:56 UTC, committed by Bjoern A. Zeeb on 24 January 2010, 14:05:56 UTC
Add security.jail.ip4_saddrsel/ip6_nosaddrsel sysctls to control whether to use source address selection (default) or the primary jail address for unbound outgoing connections. This is intended to be used by people upgrading from single-IP jails to multi-IP jails but not having to change firewall rules, application ACLs, ... but to force their connections (unless otherwise changed) to the primry jail IP they had been used for years, as well as for people prefering to implement similar policies. Note that for IPv6, if configured incorrectly, this might lead to scope violations, which single-IPv6 jails could as well, as by the design of jails. [1] Note that in contrast to FreeBSD 8.x and newer, where we have per-jail options, the sysctls are global for all jails.
