Date: Tue, 08 Apr 2014 20:26:37 +0200 From: Heiner Kallweit <heiner.kallweit@....de> To: "netdev@...r.kernel.org" <netdev@...r.kernel.org> Subject: ipv6: Should inet6_addr_del consider IFA_F_MANAGETEMPADDR? I stumbled accross the fact that inet6_addr_add as well as inet6_addr_modify consider IFA_F_TEMPORARY whilst inet6_addr_del does not. My understanding of IFA_F_MANAGETEMPADDR is that it allows userspace applications to deal with temporary addresses w/o having to create / track (and possibly delete) each and every temporary address. This works fine when creating / modifying a global address. However when a global address is deleted the orphaned temporary addresses remain. Shouldn't the userspace be able to set IFA_F_MANAGETEMPADDR also for RTM_DELADDR to signalize that the kernel should delete all related temporary addresses as well? It would be a rather small extension to manage_tempaddrs to add a "delete" parameter and set valid_lft=prefered_lft=0 for each temporary address if set. Sorry if this was discussed before and I miss something.
