In-Reply-To: <1334148649-25443-1-git-send-email-ordex-GaUfNO9RBHfsrOwW+9ziJQ@public.gmane.org>
From: Simon Wunderlich <simon.wunderlich-Y4E02TeZ33kaBlGTGt4zH4SGEyLTKazZ@public.gmane.org>
When multiple backbone gateways relay the same broadcast from the
backbone into the mesh, other nodes in the mesh may receive this
broadcast multiple times. To avoid this, the crc checksums of
received broadcasts are recorded and new broadcast packets with
the same content may be dropped if received by another gateway.

As the backbone gateways are connected to the same backbone, they
should announce the same clients on the backbone non-exclusively.

* [PATCH 08/16] batman-adv: add basic bridge loop avoidance code
From: Antonio Quartulli @ 2012-04-11 12:50 UTC (permalink / raw)

In-Reply-To: <1334148649-25443-1-git-send-email-ordex-GaUfNO9RBHfsrOwW+9ziJQ@public.gmane.org>
From: Simon Wunderlich <simon.wunderlich-Y4E02TeZ33kaBlGTGt4zH4SGEyLTKazZ@public.gmane.org>
This second version of the bridge loop avoidance for batman-adv
avoids loops between the mesh and a backbone (usually a LAN).
By connecting multiple batman-adv mesh nodes to the same ethernet
segment a loop can be created when the soft-interface is bridged
into that ethernet segment. A simple visualization of the loop
involving the most common case - a LAN as ethernet segment:
node1 <-- LAN --> node2
| |
wifi <-- mesh --> wifi
Packets from the LAN (e.g. ARP broadcasts) will circle forever from
node1 or node2 over the mesh back into the LAN.
With this patch, batman recognizes backbone gateways, nodes which are
part of the mesh and backbone/LAN at the same time. Each backbone
gateway "claims" clients from within the mesh to handle them
exclusively. By restricting that only responsible backbone gateways
may handle their claimed clients traffic, loops are effectively
avoided.

* [PATCH 07/16] batman-adv: remove old bridge loop avoidance code
From: Antonio Quartulli @ 2012-04-11 12:50 UTC (permalink / raw)
To: davem-fT/PcQaiUtIeIZ0/mPfg9Q

In-Reply-To: <1334148649-25443-1-git-send-email-ordex-GaUfNO9RBHfsrOwW+9ziJQ@public.gmane.org>
From: Simon Wunderlich <simon.wunderlich-Y4E02TeZ33kaBlGTGt4zH4SGEyLTKazZ@public.gmane.org>
The functionality is to be replaced by an improved implementation,
so first clean up.

* [PATCH 04/16] batman-adv: Replace bitarray operations with bitmap

In-Reply-To: <1334148649-25443-1-git-send-email-ordex-GaUfNO9RBHfsrOwW+9ziJQ@public.gmane.org>
From: Sven Eckelmann <sven-KaDOiPu9UxWEi8DpZVb4nw@public.gmane.org>
bitarray.c consists mostly of functionality that is already available as part
of the standard kernel API. batman-adv could use architecture optimized code
and reduce the binary size by switching to the standard functions.

In-Reply-To: <1334148649-25443-1-git-send-email-ordex-GaUfNO9RBHfsrOwW+9ziJQ@public.gmane.org>
In packet.h the numeric constant 6 is used instead of the more portable ETH_ALEN
define. This patch substitute any hardcoded value with such define.

Hello,
this is our new set of patches (actually there has been no modification from the
last pull request issued on 2011-04-07) which is now based on top of the current
net-next/master branch (commit id: 06eb4eafbdc0796d741d139a44f1253278da8611).
Let me know if there is something else wrong.
Thank you very much,
Antonio

I'd be happy to try out any other patches or help debugging this issue.
Which behavior did this patch fix exactly? can I just revert it and
try running without it?

Thanks, that information allowed me to apply the patch series and to
test it with kernel 3.4-rc2 and iSCSI target code. The test ran fine.
The failure to apply this patch series on 3.4-rc2 I had reported turned
out to be an easy to resolve merge conflict:

Regarding the "Tx descriptor busy" test: no, I didn't see it trigger, I
just put it there just in case because I suspected there could be a race
due to the lock-free tx path.
But I'm glad if you're confident that it can't happen :)

I dont understand this split thing for MTU=1500 frames.
Even using half a page per fragment, each skb :
needs 2 allocations for sk_buff and skb->head, plus one page alloc /
reference.
skb->truesize = ksize(skb->head) + sizeof(*skb) + PAGE_SIZE/2 = 512 +
256 + 2048 = 2816 bytes
With non split you have :
2 allocations for sk_buff and skb->head.
skb->truesize = ksize(skb->head) + sizeof(*skb) = 2048 + 256 = 2304
bytes
less overhead and less calls to page allocator...
This only can benefit if GRO is on, since aggregation can use fragments
and a single sk_buff, instead of a frag_list

Well I can see your config is not up to date for one thing. First I
would try `make defconfig` OR run `make menuconfig` first. Your compile
complains of a 3com driver which your .config has not enabled (probably
because it is an old .config from a kernel previous to 3.2).

I am not worried only with this message, but when I am looking at my
devices, even if the mlx4_core module is loaded, I don't have my eth
device.
Initializing is ok, but probe fails, so I can't use the device, this
is what I am worried about :).
I have two types of devices : be2net and mlx4. I want to have bonding
between them, and using an old kernel (debian lenny, 2.6.26), and the
drivers directly recompiled from mellanox website I can get it work.
Using the latest kernel (3.4.0-rc2) and using "modprobe mlx4_en" I get
the same messages related to mlx4_core, but it loads some ethernet
ports.
When booting, it detects the mlx and udev loads mlx4_core, not mlx4_en...
I will try to force it (but I am sure there is a clean way to do that ;-)).

I agree it's a separate optimization. But if we let the
number of supported modes explode
(MACVLAN_MODE_PASSTHRU_NOPROMISC MACVLAN_MODE_PASSTHRU_NOALLMULTI
....) supporting them all and combinations thereof might become a problem.
I'm looking for an interface solution that will limit this
overhead without breaking existing setups.
One idea was to have a flag that says basically "really obey device
configuration". Yes if we do this we can then split the support to
multiple patches and consider each individual one a bugfix, though if we
put a known broken solution in 3.5 there's a danger that someone will
come to depend on the broken behaviour. Other ideas?

With all the changes in this series it is still possible to fit a
maximum standard MTU frame and the shinfo on the same 4K page while also
have the skb_shared_info up to and including frag [0] aligned to the
same 64 byte cache line.
The only exception is destructor_arg on 64 bit which is on the preceding
cache line but that is not a field used in any hot path.

I think it does work for 32 bit pointers. What issue to do you see with
64K pages?
