Hello,

I did the following:

cassiopeia:~# sysctl net.ipv6.conf.all.use_tempaddr net.ipv6.conf.all.use_tempaddr = 0

cassiopeia:~# sysctl net.ipv6.conf.eth0.use_tempaddr net.ipv6.conf.eth0.use_tempaddr = 0

cassiopeia:~# sysctl -w net.ipv6.conf.all.use_tempaddr=1 net.ipv6.conf.all.use_tempaddr = 1

cassiopeia:~# sysctl net.ipv6.conf.all.use_tempaddr net.ipv6.conf.all.use_tempaddr = 1

cassiopeia:~# sysctl net.ipv6.conf.eth0.use_tempaddr net.ipv6.conf.eth0.use_tempaddr = 0

Here I would have expected that eth0's use_tempaddr is 1, too. The problem is not that this entry isn't writeable:

cassiopeia:~# sysctl -w net.ipv6.conf.eth0.use_tempaddr=1 net.ipv6.conf.eth0.use_tempaddr = 1

cassiopeia:~# sysctl net.ipv6.conf.eth0.use_tempaddr net.ipv6.conf.eth0.use_tempaddr = 1

I got the same results when using net.ipv4.conf.all.rp_filter (and net.ipv4.conf.eth0.rp_filter resp.)

Is this a bug or just my failure to see how conf/all works?

Best regards Uwe
