Each routing protocol has its own metric semantic and
therefore is the protocol itself the only component able to
compare two metrics to check their "similarity".
This new API allows each routing protocol to implement its
own logic and make the external code protocol agnostic.

Each routing protocol has its own metric and private
variables, therefore it is useful to introduce a new API
for originator information printing.
This API needs to be implemented by each protocol in order
to provide its specific originator table output.

The code is broken and does not constrain sysctl_tcp_mem as
tcp_update_limit does. With the result that it allows the cgroup tcp
memory limits to be bypassed.
The semantics are broken as the settings are not per netns and are in a
per netns table, and instead looks at current.
Since the code is broken in both design and implementation and does not
implement the functionality for which it was written remove it.

Antonio Quartulli says:
====================
this is another batch intended for net-next/linux-3.13.
This pull request is a bit bigger than usual, but 6 patches are very small
(three of them are about email updates)..
Patch 1 is fixing a previous merge conflict resolution that went wrong
(I realised that only now while checking other patches..).
Patches from 2 to 4 that are updating our emails in all the proper files
(Documentation/, headers and MAINTAINERS).
Patches 5, 6 and 7 are bringing a big improvement to the TranslationTable
component: it is now able to group non-mesh clients based on the VLAN they
belong to. In this way a lot a new enhancements are now possible thanks to the
fact that each batman-adv behaviour can be applied on a per VLAN basis.
And, of course, in patches from 8 to 12 you have some of the enhancements I was
talking about:
- make the batman-Gateway selection VLAN dependent
- make DAT (Distributed ARP Table) group ARP entries on a VLAN basis (this
allows DAT to work even when the admin decided to use the same IP subnet on
different VLANs)
- make the AP-Isolation behaviour switchable on each VLAN independently
- export VLAN specific attributes via sysfs. Switches like the AP-Isolation are
now exported once per VLAN (backward compatibility of the sysfs interface has
been preserved)
Patches 13 and 14 are small code cleanups.
Patch 15 is a minor improvement in the TT locking mechanism.
Patches 16 and 17 are other enhancements to the TT component. Those allow a
node to parse a "non-mesh client announcement message" and accept only those
TT entries belonging to certain VLANs.
Patch 18 exploits this parse&accept mechanism to make the Bridge Loop Avoidance
component reject only TT entries connected to the VLAN where it is operating.
Previous to this change, BLA was rejecting all the entries coming from any other
Backbone node, regardless of the VLAN (for more details about how the Bridge
Loop Avoidance works please check [1]).

net_get_random_once

net_get_random_once is a new macro which handles the initialization
of secret keys. It is possible to call it in the fast path. Only the
initialization depends on the spinlock and is rather slow. Otherwise
it should get used just before the key is used to delay the entropy
extration as late as possible to get better randomness. It returns true
if the key got initialized.
The usage of static_keys for net_get_random_once is a bit uncommon so
it needs some further explanation why this actually works:
=== In the simple non-HAVE_JUMP_LABEL case we actually have ===
no constrains to use static_key_(true|false) on keys initialized with
STATIC_KEY_INIT_(FALSE|TRUE). So this path just expands in favor of
the likely case that the initialization is already done. The key is
initialized like this:
___done_key = { .enabled = ATOMIC_INIT(0) }
The check
if (!static_key_true(&___done_key)) \
expands into (pseudo code)
if (!likely(___done_key > 0))
, so we take the fast path as soon as ___done_key is increased from the
helper function.
=== If HAVE_JUMP_LABELs are available this depends ===
on patching of jumps into the prepared NOPs, which is done in
jump_label_init at boot-up time (from start_kernel). It is forbidden
and dangerous to use net_get_random_once in functions which are called
before that!
At compilation time NOPs are generated at the call sites of
net_get_random_once. E.g. net/ipv6/inet6_hashtable.c:inet6_ehashfn (we
need to call net_get_random_once two times in inet6_ehashfn, so two NOPs):
71: 0f 1f 44 00 00 nopl 0x0(%rax,%rax,1)
76: 0f 1f 44 00 00 nopl 0x0(%rax,%rax,1)
Both will be patched to the actual jumps to the end of the function to
call __net_get_random_once at boot time as explained above.
arch_static_branch is optimized and inlined for false as return value and
actually also returns false in case the NOP is placed in the instruction
stream. So in the fast case we get a "return false". But because we
initialize ___done_key with (enabled != (entries & 1)) this call-site
will get patched up at boot thus returning true. The final check looks
like this:
if (!static_key_true(&___done_key)) \
___ret = __net_get_random_once(buf, \
expands to
if (!!static_key_false(&___done_key)) \
___ret = __net_get_random_once(buf, \
So we get true at boot time and as soon as static_key_slow_inc is called
on the key it will invert the logic and return false for the fast path.
static_key_slow_inc will change the branch because it got initialized
with .enabled == 0. After static_key_slow_inc is called on the key the
branch is replaced with a nop again.
=== Misc: ===
The helper defers the increment into a workqueue so we don't
have problems calling this code from atomic sections. A seperate boolean
(___done) guards the case where we enter net_get_random_once again before
the increment happend.

While implementing GSO/TSO support for IPIP, I found skb_segment()
was assuming network header was immediately following mac header.
Its not really true in the case inet_gso_segment() is stacked :
By the time tcp_gso_segment() is called, network header points
to the inner IP header.
Let's instead assume nothing and pick the current offsets found in
original skb, we have skb_headers_offset_update() helper for that.
Also move the csum_start update inside skb_headers_offset_update()

The backbone gw check has to be VLAN specific so that code
using it can specify VID where the check has to be done.
In the TT code, the check has been moved into the
tt_global_add() function so that it can be performed on a
per-entry basis instead of ignoring all the TT data received
from another backbone node. Only TT global entries belonging
to the VLAN where the backbone node is connected to are
skipped.
All the other spots where the TT code was checking whether a
node is a backbone have been removed.
Moreover, batadv_bla_is_backbone_gw_orig() now returns bool
since it used to return only 1 or 0.

This change allows nodes to handle the TT table on a
per-VLAN basis. This is needed because nodes may have to
store only some of the global entries advertised by another
node.
In this scenario such nodes would re-create only a partial
global table and would not be able to compute a correct CRC
anymore.
This patch splits the logic and introduces one CRC per VLAN.
In this way a node fetching only some entries belonging to
some VLANs is still able to compute the needed CRCs and
still check the table correctness.
With this patch the shape of the TVLV-TT is changed too
because now a node needs to advertise all the CRCs of all
the VLANs that it is wired to.
The debug output of the local Translation Table now shows
the CRC along with each entry since there is not a common
value for the entire table anymore.

A TT response may be prepared and sent while the local or
global translation table is getting updated.
The worst case is when one of the tables is accessed after
its content has been recently updated but the metadata
(TTVN/CRC) has not yet. In this case the reader will get a
table content which does not match the TTVN/CRC.
This will lead to an inconsistent state and so to a TT
recovery.
To avoid entering this situation, put a lock around those TT
operations recomputing the metadata and around the TT
Response creation (the latter is the only reader that
accesses the metadata together with the table).

The subfolder is named "vlan%VID" and it is created inside

Since batman-adv is now fully VLAN-aware, a proper framework
able to handle per-vlan-interface attributes is needed.
Those attributes will affect the associated VLAN interface
only, rather than the real soft_iface (which would result
in every vlan interface having the same attribute
configuration).
To make the code simpler and easier to extend, attributes
associated to the standalone soft_iface are now treated
like belonging to yet another vlan having a special vid.
This vid is different from the others because it is made up
by all zeros and the VLAN_HAS_TAG bit is not set.
