[Bug 986395] NFS client is using temp IPv6 address for mount
http://bugzilla.novell.com/show_bug.cgi?id=986395 http://bugzilla.novell.com/show_bug.cgi?id=986395#c16 --- Comment #16 from Jiri Bohac <jbohac@suse.com> --- (In reply to Neil Brown from comment #15)
Other things are weird though.
It seems fairly easy to trigger the
IPv6: ipv6_create_tempaddr: regeneration time exceeded - disabled temporary address support
message, which seems like it should be nearly impossible on a network with half a dozen hosts. And "ip -6 addr" reports e.g.
inet6 2406:3400:c:15:7036:9572:6256:d431/64 scope global temporary dynamic valid_lft 277sec preferred_lft 14177sec
ha! thanks for finding this; it's caused by net.ipv6.conf.*.max_desync_factor being larger than net.ipv6.conf.*temp_prefered_lft It results in an uderflow, it's a bug, I'll create a patch to fix this. For now, please set max_desync_factor to 0 when doing these experiments with a low temp_prefered_lft.
but now establishing an IPv6 connection doesn't create a new temp address, but just uses the permanent one.
The address is never created by making a connection. It should be created asynchronously by a timer. But the whole privacy extensions got disabled at the moment the "ipv6_create_tempaddr: regeneration time exceeded - disabled temporary address support" warning
OK, more weirdness.. My temp address became valid_lft 0sec preferred_lft 14100sec
not sure, but this is hopefully still the same problem with the max_desync_factor. -- You are receiving this mail because: You are on the CC list for the bug.
