Update the code to handle some of the differences between
RFC 3041 and RFC 4941, which obsoletes it. Also a couple
of janitorial fixes.- Allow router advertisements to increase the lifetime of
temporary addresses. This was not allowed by RFC 3041,
but is specified by RFC 4941. It is useful when RA
lifetimes are lower than TEMP_{VALID,PREFERRED}_LIFETIME:
in this case, the previous code would delete or deprecate
addresses prematurely.- Change the default of MAX_RETRY to 3 per RFC 4941.
- Add a comment to clarify that the preferred and valid
lifetimes in inet6_ifaddr are relative to the timestamp.- Shorten lines to 80 characters in a couple of places.

These header files are never installed to user consumption, so any
__KERNEL__ cpp checks are superfluous.Projects should also not copy these files into their userland utility
sources and try to use them there. If they insist on doing so, the
onus is on them to sanitize the headers as needed.Signed-off-by: David S. Miller

Clean up a missing exit path in the ipv6 module init routines. In
addrconf_init we call ipv6_addr_label_init which calls register_pernet_subsys
for the ipv6_addr_label_ops structure. But if module loading fails, or if the
ipv6 module is removed, there is no corresponding unregister_pernet_subsys call,
which leaves a now-bogus address on the pernet_list, leading to oopses in
subsequent registrations. This patch cleans up both the failed load path and
the unload path. Tested by myself with good results.Signed-off-by: Neil Horman

Update rcu_dereference() primitives to use new lockdep-based
checking. The rcu_dereference() in __in6_dev_get() may be
protected either by rcu_read_lock() or RTNL, per Eric Dumazet.
The rcu_dereference() in __sk_free() is protected by the fact
that it is never reached if an update could change it. Check
for this by using rcu_dereference_check() to verify that the
struct sock's ->sk_wmem_alloc counter is zero.Acked-by: Eric Dumazet

This patch fixes commit e36b9d16c6a6d0f59803b3ef04ff3c22c3844c10. The approach
there is to call dev_close()/dev_open() whenever the device type is changed in
order to remap the device IP multicast addresses to HW multicast addresses.
This approach suffers from 2 drawbacks:*. It assumes tha the device is UP when calling dev_close(), or otherwise
dev_close() has no affect. It is worth to mention that initscripts (Redhat)
and sysconfig (Suse) doesn't act the same in this matter.
*. dev_close() has other side affects, like deleting entries from the routing
table, which might be unnecessary.The fix here is to directly remap the IP multicast addresses to HW multicast
addresses for a bonding device that changes its type, and nothing else.Reported-by: Jason Gunthorpe

This pacth makes IPv6 address labels per network namespace.
It keeps the global label tables, ip6addrlbl_table, but
adds a 'net' member to each ip6addrlbl_entry.
This new member is taken into account when matching labels.Changelog
=========
* v1: Initial version
* v2:
* Minize the penalty when network namespaces are not configured:
* the 'net' member is added only if CONFIG_NET_NS is
defined. This saves space when network namespaces are not
configured.
* 'net' value is retrieved with the inlined function
ip6addrlbl_net() that always return &init_net when
CONFIG_NET_NS is not defined.
* 'net' member in ip6addrlbl_entry renamed to the less generic
'lbl_net' name (helps code search).Signed-off-by: Benjamin Thery

module, and is configured using extensions to the "iproute2"
utility. The diffs are specific to the Linux 2.6.24-rc2 kernel
distribution.This version includes the diff for ./include/linux/if.h which was
missing in the v2.4 submission and is needed to make the
patch compile. The patch has been installed, compiled and

This patch makes MIPv6 loadable module named "mip6".
Here is a modprobe.conf(5) example to load it automatically
when user application uses XFRM state for MIPv6:alias xfrm-type-10-43 mip6
alias xfrm-type-10-60 mip6Some MIPv6 feature is not included by this modular, however,
it should not be affected to other features like either IPsec
or IPv6 with and without the patch.
We may discuss XFRM, MH (RAW socket) and ancillary data/sockopt
separately for future work.Loadable features:
* MH receiving check (to send ICMP error back)
* RO header parsing and building (i.e. RH2 and HAO in DSTOPTS)
* XFRM policy/state database handling for ROThese are NOT covered as loadable:
* Home Address flags and its rule on source address selection
* XFRM sub policy (depends on its own kernel option)
* XFRM functions to receive RO as IPv6 extension header
* MH sending/receiving through raw socket if user application
opens it (since raw socket allows to do so)
* RH2 sending as ancillary data
* RH2 operation with setsockopt(2)Signed-off-by: Masahide NAKAMURA

Nominally an autoconfigured IPv6 address is added to an interface in the
Tentative state (as per RFC 2462). Addresses in this state remain in this
state while the Duplicate Address Detection process operates on them to
determine their uniqueness on the network. During this period, these
tentative addresses may not be used for communication, increasing the time
before a node may be able to communicate on a network. Using Optimistic
Duplicate Address Detection, autoconfigured addresses may be used
immediately for communication on the network, as long as certain rules are
followed to avoid conflicts with other nodes during the Duplicate Address
Detection process.Signed-off-by: Neil Horman
