commit 2c8cec5c10 (Cache learned PMTU information in inetpeer) added
an extra inet_putpeer() call in ip_rt_update_pmtu().
This results in various problems, since we can free one inetpeer, while
it is still in use.

In commit 9435eb1cf0
("ipv4: Implement __ip_dev_find using new interface address hash.")
we reimplemented __ip_dev_find() so that it doesn't have to
do a full FIB table lookup.
Instead, it consults a hash table of addresses configured to
interfaces.
This works identically to the old code in all except one case,
and that is for loopback subnets.
The old code would match the loopback device for any IP address
that falls within a subnet configured to the loopback device.
Handle this corner case by doing the FIB lookup.
We could implement this via inet_addr_onlink() but:
1) Someone could configure many addresses to loopback and
inet_addr_onlink() is a simple list traversal.
2) We know the old code works.

In the current undo logic, cwnd is moderated after it was restored
to the value prior entering fast-recovery. It was moderated first
in tcp_try_undo_recovery then again in tcp_complete_cwr.
Since the undo indicates recovery was false, these moderations
are not necessary. If the undo is triggered when most of the
outstanding data have been acknowledged, the (restored) cwnd is
falsely pulled down to a small value.
This patch removes these cwnd moderations if cwnd is undone
a) during fast-recovery
b) by receiving DSACKs past fast-recovery

The ipv6_dev_get_saddr() is currently called with an uninitialized
destination address. Although in tests it usually seemed to nevertheless
always fetch the right source address, there seems to be a possible race
condition.
Therefore this commit changes this, first setting the destination
address and only after that fetching the source address.

Optimize the calling of fib_add_ifaddr for all

The secondary address promotion relies on fib_sync_down_addr
to remove all routes created for the secondary addresses when
the old primary address is deleted. It does not happen for cases
when the primary address is also in another subnet. Fix that
by deleting local and broadcast routes for all secondaries while
they are on device list and by faking that all addresses from
this subnet are to be deleted. It relies on fib_del_ifaddr being
able to ignore the IPs from the concerned subnet while checking
for duplication.

Alex Sidorenko reported for problems with local
routes left after IP addresses are deleted. It happens
when same IPs are used in more than one subnet for the
device.
Fix fib_del_ifaddr to restrict the checks for duplicate
local and broadcast addresses only to the IFAs that use
our primary IFA or another primary IFA with same address.
And we expect the prefsrc to be matched when the routes
are deleted because it is possible they to differ only by
prefsrc. This patch prevents local and broadcast routes
to be leaked until their primary IP is deleted finally
from the box.
As the secondary address promotion needs to delete
the routes for all secondaries that used the old primary IFA,
add option to ignore these secondaries from the checks and
to assume they are already deleted, so that we can safely
delete the route while these IFAs are still on the device list.

fib_table_delete forgets to match the routes by prefsrc.
Callers can specify known IP in fc_prefsrc and we should remove
the exact route. This is needed for cases when same local or
broadcast addresses are used in different subnets and the
routes differ only in prefsrc. All callers that do not provide
fc_prefsrc will ignore the route prefsrc as before and will
delete the first occurence. That is how the ip route del default
magic works.
Current callers are:
- ip_rt_ioctl where rtentry_to_fib_config provides fc_prefsrc only
when the provided device name matches IP label with colon.
- inet_rtm_delroute where RTA_PREFSRC is optional too
- fib_magic which deals with routes when deleting addresses
and where the fc_prefsrc is always set with the primary IP
for the concerned IFA.

When I was fixing issues with unregisgtering tables under /proc/sys/net/ipv6/neigh
by adding a mount point it appears I missed a critical ordering issue, in the
ipv6 initialization. I had not realized that ipv6_sysctl_register is called
at the very end of the ipv6 initialization and in particular after we call
neigh_sysctl_register from ndisc_init.
"neigh" needs to be initialized in ipv6_static_sysctl_register which is
the first ipv6 table to initialized, and definitely before ndisc_init.
This removes the weirdness of duplicate tables while still providing a
"neigh" mount point which prevents races in sysctl unregistering.
