ipv6: Set default hoplimit as zero.

2012-10-25T03:14:17+00:00

Commit a02e4b7dae4551(Demark default hoplimit as zero) only changes the
hoplimit checking condition and default value in ip6_dst_hoplimit, not
zeros all hoplimit default value.

Keep the zeroing ip6_template_metrics[RTAX_HOPLIMIT - 1] to force it as
const, cause as a37e6e344910(net: force dst_default_metrics to const
section)

ipv6: release reference of ip6_null_entry's dst entry in __ip6_del_rt

2012-10-04T20:00:07+00:00

as we hold dst_entry before we call __ip6_del_rt,
so we should alse call dst_release not only return
-ENOENT when the rt6_info is ip6_null_entry.

and we already hold the dst entry, so I think it's
safe to call dst_release out of the write-read lock.

overlapping changes.

qmi_wwan and bat_iv_ogm were of the "use HEAD" variety.

ipv6: recursive check rt->dst.from when call rt6_check_expired

2012-09-19T19:35:33+00:00

If dst cache dst_a copies from dst_b, and dst_b copies from dst_c, check
if dst_a is expired or not, we should not end with dst_a->dst.from, dst_b,
we should check dst_c.

ipv6: use net->rt_genid to check dst validity

2012-09-18T19:57:03+00:00

IPv6 dst should take care of rt_genid too. When a xfrm policy is inserted or
deleted, all dst should be invalidated.
To force the validation, dst entries should be created with ->obsolete set to
DST_OBSOLETE_FORCE_CHK. This was already the case for all functions calling
ip6_dst_alloc(), except for ip6_rt_copy().

As a consequence, we can remove the specific code in inet6_connection_sock.

netlink: Rename pid to portid to avoid confusion

2012-09-10T19:30:41+00:00

It is a frequent mistake to confuse the netlink port identifier with a
process identifier.  Try to reduce this confusion by renaming fields
that hold port identifiers portid instead of pid.

I have carefully avoided changing the structures exported to
userspace to avoid changing the userspace API.

I have successfully built an allyesconfig kernel with this change.
