If new_mtu is very large then "new_mtu + ETH_HLEN + ETH_FCS_LEN" can
wrap and the check on the next line can underflow. This is one of those
bugs which can be triggered by the user if you have namespaces
configured.

Also since this is something the user can trigger then we don't want to
have dev_err() message.

This is a static checker fix and I'm not sure what the impact is.

Antonio Quartulli says:

====================
this is another set of changes intended for net-next/linux-3.13.
(probably our last pull request for this cycle)

Patches 1 and 2 reshape two of our main data structures in a way that they can
easily be extended in the future to accommodate new routing protocols.

Patches from 3 to 9 improve our routing protocol API and its users so that all
the protocol-related code is not mixed up with the other components anymore.

Patch 10 limits the local Translation Table maximum size to a value such that it
can be fully transfered over the air if needed. This value depends on
fragmentation being enabled or not and on the mtu values.

Patch 11 makes batman-adv send a uevent in case of soft-interface destruction
while a "bat-Gateway" was configured (this informs userspace about the GW not
being available anymore).

Patches 13 and 14 enable the TT component to detect non-mesh client flag
changes at runtime (till now those flags where set upon client detection and
were not changed anymore).

Patch 16 is a generalisation of our user-to-kernel space communication (and
viceversa) used to exchange ICMP packets to send/received to/from the mesh
network. Now it can easily accommodate new ICMP packet types without breaking
the existing userspace API anymore.

Remaining patches are minor changes and cleanups.

initialize fragment hash secrets with net_get_random_once

This series switches the inet_frag.rnd hash initialization to
net_get_random_once.

Included patches:
 ipv4: initialize ip4_frags hash secret as late
 ipv6: split inet6_hash_frag for netfilter and
 inet: remove old fragmentation hash initializing
====================
Signed-off-by: NDavid S. Miller <davem@davemloft.net>

All fragmentation hash secrets now get initialized by their
corresponding hash function with net_get_random_once. Thus we can
eliminate the initial seeding.

Also provide a comment that hash secret seeding happens at the first
call to the corresponding hashing function.

Defer the fragmentation hash secret initialization for IPv6 like the
previous patch did for IPv4.

Because the netfilter logic reuses the hash secret we have to split it
first. Thus introduce a new nf_hash_frag function which takes care to
seed the hash secret.

Defer the generation of the first hash secret for the ipv4 fragmentation
cache as late as possible.

ip4_frags.rnd gets initial seeded by inet_frags_init and regulary
reseeded by inet_frag_secret_rebuild. Either we call ipqhashfn directly
from ip_fragment.c in which case we initialize the secret directly.

If we first get called by inet_frag_secret_rebuild we install a new secret
by a manual call to get_random_bytes. This secret will be overwritten
as soon as the first call to ipqhashfn happens. This is safe because we
won't race while publishing the new secrets with anyone else.

Currently net_secret_init does not get inlined, so we always have a call
to net_secret_init even in the fast path.

Let's specify net_secret_init as __always_inline so we have the nop in

at the epilogue of the function.

Instead of handling icmp packets only up to length of icmp_packet_rr,
the code should handle any icmp length size. Therefore the length
truncating is moved to when the packet is actually sent to userspace
(this does not support lengths longer than icmp_packet_rr yet). Longer
packets are forwarded without truncating.

This patch also cleans up some parts where the icmp header struct could
be used instead of other icmp_packet(_rr) structs to make the code more
readable.

Flags covered by TT_SYNC_MASK are kept in sync among the
nodes in the network and therefore they have to be
considered while computing the global/local table CRC.

In this way a generic originator is able to understand if
its table contains the correct flags or not.

Bits from 4 to 7 in the TT flags fields are now reserved for
"synchronized" flags only.

This allows future developers to add more flags of this type
without breaking compatibility.

It's important to note that not all the remote TT flags are
synchronised. This comes from the fact that some flags are
used to inject an information once only.

Some flags (i.e. the WIFI flag) may change after that the
related client has already been announced. However it is
useful to informa the rest of the network about this change.

value.

This mechanism can be easily exploited by future flags that
may need the same treatment.

The local translation table size is limited by what can be
transferred from one node to another via a full table request.

The number of entries fitting into a full table request depend
on whether the fragmentation is enabled or not. Therefore this
patch introduces a max table size check and refuses to add
more local clients when that size is reached. Moreover, if the
max full table packet size changes (MTU change or fragmentation
is disabled) the local table is downsized instantaneously.

Some operations executed on an orig_node depends on the
current routing algorithm being used. To easily make this
mechanism routing algorithm agnostic add a orig_node
specific API that each algorithm can populate with its own
routines.

Such routines are then invoked by the code when needed,
without knowing which routing algorithm is currently in use

With this patch 3 API functions are added:
- orig_free (to free routing depending internal structs)
- orig_add_if (to change the inner state of an orig_node
  when a new hard interface is added)
- orig_del_if (to change the inner state of an orig_node
