https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D245103 --- Comment #11 from Marek Zarychta <zarychtam@plan-b.pwste.edu.pl> --- (In reply to Zhenlei Huang from comment #9) Yes, and we have the patch[1] from one of the authors of the RFC 8981. The patch[1]=20 - reduces the Valid Lifetime from 1 week to 2 days, - limits the number of concurrent temporary addresses per prefix to 2, - deprecates the use of MD5 as the algorithm for computing the temporary II= Ds, - introduces using different interface-ids for each temporary address. RFC 8981 also "Removes the recommendation that temporary addresses be disab= led by default. This is in line with BCP 188 ([RFC7258]) and also with BCP 204 ([RFC7934]).", so perhaps also "net.inet6.ip6.use_tempaddr" should be bumpe= d to "1"" Leaving "net.inet6.ip6.prefer_tempaddr" at "0" (as is) should not introduce any breakage.=20 Perhaps Fernando's patch could be put on the review on Phabricator and proceeded further?
