Package: linux-image-2.6.26-1-686
Version: 2.6.26-13
Severity: normal
Documentation for temp_prefered_lft states that:
#v+
temp_prefered_lft - INTEGER
Preferred lifetime (in seconds) for temporary addresses.
Default: 86400 (1 day)
#v-
But this setting seems to be ignored:
#v+
# dev="wire"
# ip link set $dev down
# sysctl -w net.ipv6.conf.$dev.use_tempaddr=2
net.ipv6.conf.wire.use_tempaddr = 2
# sysctl -w net.ipv6.conf.$dev.max_desync_factor=0
net.ipv6.conf.wire.max_desync_factor = 0
# sysctl -w net.ipv6.conf.$dev.temp_valid_lft=10
net.ipv6.conf.wire.temp_valid_lft = 10
# sysctl -w net.ipv6.conf.$dev.temp_prefered_lft=6
net.ipv6.conf.wire.temp_prefered_lft = 6
# ip address flush dev $dev
# ip link set $dev up
# sleep 5 # waiting for RA
# ip -6 a sh dev $dev secondary

Meanwhile, temp_valid_lft seems to be respected.
