everywhere where this is possible in net/ipv6/*.c .

The argument of rt6_route_add() for adding a route is not the
expiration time in jiffies nor in clock_t, but the lifetime
(or time left before expiration) in clock_t.

Because of the confusion, we sometimes saw several strange errors
(FAILs) in TAHI IPv6 Ready Logo Phase-2 Self Test.

Herbert Xu efacfbcb6c [IPV6]: Fix rtnetlink dump infinite loop
The recent change to netlink dump "done" callback handling broke IPv6
which played dirty tricks with the "done" callback.  This causes an
infinite loop during a dump.

The following patch fixes it.

This bug was reported by Jeff Garzik.

Yan Zheng 9d17f21893 [IPV6]: Fix behavior of ip6_route_input() for link local address
I find that linux will reply echo request destined to an address which
belongs to an interface other than the one from which the request received.
This behavior doesn't make sense for link local address.

YOSHIFUJI Hideaki <yoshfuji@linux-ipv6.org> said:

Please note that sender does need to setup neighbor entry by hand to reproduce
this bug.  (Link-local address on eth1 is not visible on eth0, from the point
of view of neighbor discovery in IPv6.)

Jamal Hadi Salim 0d51aa80a9 [IPV6]: V6 route events reported with wrong netlink PID and seq number
Essentially netlink at the moment always reports a pid and sequence of 0
always for v6 route activities. 
To understand the repurcassions of this look at:
http://lists.quagga.net/pipermail/quagga-dev/2005-June/003507.html

While fixing this, i took the liberty to resolve the outstanding issue
of IPV6 routes inserted via ioctls to have the correct pids as well.

This patch tries to behave as close as possible to the v4 routes i.e
maintains whatever PID the socket issuing the command owns as opposed to
the process. That made the patch a little bulky.

I have tested against both netlink derived utility to add/del routes as
well as ioctl derived one. The Quagga folks have tested against quagga.
This fixes the problem and so far hasnt been detected to introduce any
new issues.

Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
