* [PATCH 0/6] ipv6: ip6mr: support multiple independant multicast routing instances
From: kaber @ 2010-05-11 14:02 UTC (permalink / raw)
To: davem; +Cc: netdev
The following patches add support for multiple independant IPv6 multicast
routing instances. This can be useful to seperate traffic when building
a multicast router that is serving multiple independant networks.
The patchset is pretty much a straight forward port from IPv4 with no
significant differences.
The patchset consists of the following parts:
- Patch 01-04 contain some preparatory work and cleanup for supporting
multiple multicast routing instances.
- Patch 05 contains the actual changes to support multiple multicast
routing instances.
- Patch 06 adds support for dumping multicast routing routes from all
tables over netlink.
These patches have been tested using pim6sd and mrd6.
Please apply or pull from:
git://git.kernel.org/pub/scm/linux/kernel/git/kaber/ipmr-2.6.git master
Thanks!

* [PATCH 2/6] ipv6: ip6mr: remove net pointer from struct mfc6_cache
From: kaber @ 2010-05-11 14:02 UTC (permalink / raw)
To: davem; +Cc: netdev
In-Reply-To: <1273586551-3521-1-git-send-email-kaber@trash.net>
From: Patrick McHardy <kaber@trash.net>
Now that cache entries in unres_queue don't need to be distinguished by their
network namespace pointer anymore, we can remove it from struct mfc6_cache
add pass the namespace as function argument to the functions that need it.

* [PATCH 6/6] ipv6: ip6mr: add support for dumping routing tables over netlink
From: kaber @ 2010-05-11 14:02 UTC (permalink / raw)
To: davem; +Cc: netdev
In-Reply-To: <1273586551-3521-1-git-send-email-kaber@trash.net>
From: Patrick McHardy <kaber@trash.net>
The ip6mr /proc interface (ip6_mr_cache) can't be extended to dump routes
from any tables but the main table in a backwards compatible fashion since
the output format ends in a variable amount of output interfaces.
Introduce a new netlink interface to dump multicast routes from all tables,
similar to the netlink interface for regular routes.

* [PATCH 5/6] ipv6: ip6mr: support multiple tables
From: kaber @ 2010-05-11 14:02 UTC (permalink / raw)
To: davem; +Cc: netdev
In-Reply-To: <1273586551-3521-1-git-send-email-kaber@trash.net>
From: Patrick McHardy <kaber@trash.net>
This patch adds support for multiple independant multicast routing instances,
named "tables".
Userspace multicast routing daemons can bind to a specific table instance by
issuing a setsockopt call using a new option MRT6_TABLE. The table number is
stored in the raw socket data and affects all following ip6mr setsockopt(),
getsockopt() and ioctl() calls. By default, a single table (RT6_TABLE_DFLT)
is created with a default routing rule pointing to it. Newly created pim6reg
devices have the table number appended ("pim6regX"), with the exception of
devices created in the default table, which are named just "pim6reg" for
compatibility reasons.
Packets are directed to a specific table instance using routing rules,
similar to how regular routing rules work. Currently iif, oif and mark
are supported as keys, source and destination addresses could be supported
additionally.
Example usage:
- bind pimd/xorp/... to a specific table:
uint32_t table = 123;
setsockopt(fd, SOL_IPV6, MRT6_TABLE, &table, sizeof(table));
- create routing rules directing packets to the new table:
# ip -6 mrule add iif eth0 lookup 123
# ip -6 mrule add oif eth0 lookup 123

* [PATCH 1/6] ipv6: ip6mr: move unres_queue and timer to per-namespace data
From: kaber @ 2010-05-11 14:02 UTC (permalink / raw)
To: davem; +Cc: netdev
In-Reply-To: <1273586551-3521-1-git-send-email-kaber@trash.net>
From: Patrick McHardy <kaber@trash.net>
The unres_queue is currently shared between all namespaces. Following patches
will additionally allow to create multiple multicast routing tables in each
namespace. Having a single shared queue for all these users seems to excessive,
move the queue and the cleanup timer to the per-namespace data to unshare it.
As a side-effect, this fixes a bug in the seq file iteration functions: the
first entry returned is always from the current namespace, entries returned
after that may belong to any namespace.
Signed-off-by: Patrick McHardy <kaber@trash.net>

Ok. I believe we will at least have to add the same kind of setup
to bridged devices as well, not just macvtap.
For SR-IOV with device assignment, I'm not sure. This will be more
important when adapters show up that actually support VEPA in hardware
and don't have their own switch, but even for those with an integrated
switch, it would be nice if we could use VDP correctly.

Possibly yes, but that will depend on how the firmware does this. It
may also be possible that adapters implement this similar to what enic
does, which does not expose the S-VLAN ID at all and uses the VF
number as the identifier.
Maybe we should leave out the CDCP stuff for now, until we start seeing
hardware for it.

That is exactly what I used to see on what I think is a similar system

may need a BIOS update, so I'll see if we can work to get him an updated

Further, at least in the context of netperf benchmarking, depending on the
quantity of offloads, and the speed of your cores, you may want to use the
global -T option to bind netperf, and particularly netserver to a core other
than the one on which the interrupts were processed.
It is also good to check whether any of the cores in the system are at or near
saturation (eg 100%ish utilization).
happy benchmarking,

We can easily push right at 10Gbps full-duplex on two ports (sending to self)
with a 2-port 82599 NIC, 3.3Ghz quad-core Intel core i7 6GT/s processor, etc.
In fact, recent testing with a 2-port 10G NIC and a bunch of intel 1G ports showed about
50Gbps aggregate bandwidth across the network on such a system. (We were using 9000 MTU
for the 50Gbps test, but can reach 10G send-to-self with 1500 MTU on the 10G ports by themselves.)
This is all using a slightly modified pktgen, but normal pktgen should do just fine.

The multi-channel setup and VDP can live, and are designed to live
together:
- multiple channels per link (setup by the bridge) -- CDCP
- association of a vsi (virtual interface) to bridge ports -- VDP
However, their implementation can be pursued separately.

The problem with defining a 'name' as the lookup key to another database is
that one then requires additional management mechanisms to describe,
maintain, and map to the real values needed. It lands in admin's lap
anyway by a different path.

Agree. See Stefan's last patch in libvirt - it converges 802.1Qbh/portprofile
and 802.1Qbg quite well. The netlink message can be deciphered by the
recipient and meets the advantages below. (Or, one could use a direct
unix domain socket to communicate with a daemon as well).

Yes, but that will add another mechanism to set the mappings. The
xml posted (on libvirt) defines the vsi values and avoids this
additional management. It also allows for port-profile name for 802.1Qbh.

Strictly speaking, the above is incorrect, as the duplicate
suppression is turned on for the active-backup inactive slaves as well
as 802.3ad ports that are disabled (any slave that gets the "inactive"
flag bit set).

Reading netdev lately, it sure looks like everybody wants ways
to shut off or bypass the duplicate suppression.

Since this is really meant for the queue tagging stuff in the
next patch, should this really be something that's enabled automatically
if the queues are configured in such a way that the inactive slave is
going to receive traffic?
I also wonder if something like this would satisfy the FCOE guys
without making __netif_receive_skb / skb_bond_should_drop even more
complicated than they already are.

Two thoughts (presuming for the moment that this doesn't
change): first, bump the driver version and mention when it was added;
second, mention that this only applies to active-backup mode.

* [PATCH RFC] vhost: fix barrier pairing
From: Michael S. Tsirkin @ 2010-05-11 17:26 UTC (permalink / raw)
To: Michael S. Tsirkin, Juan Quintela, Rusty Russell, David S. Miller,
"Paul E. McKenney" <paulmc
According to memory-barriers.txt, an smp memory barrier
should always be paired with another smp memory barrier,
and I quote "a lack of appropriate pairing is almost certainly an
error".
In case of vhost, failure to flush out used index
update before looking at the interrupt disable flag
could result in missed interrupts, resulting in
networking hang under stress.
This might happen when flags read bypasses used index write.
So we see interrupts disabled and do not interrupt, at the
same time guest writes flags value to enable interrupt,
reads an old used index value, thinks that
used ring is empty and waits for interrupt.
Note: the barrier we pair with here is in
drivers/virtio/virtio_ring.c, function
vring_enable_cb.
Signed-off-by: Michael S. Tsirkin <mst@redhat.com>

Dave, I think this is needed in 2.6.34, I'll send a pull
request after doing some more testing.
Rusty, Juan, could you take a look as well please?
Thanks!

* [PATCH net-next] net: Remove unnecessary returns from void function()s
From: Joe Perches @ 2010-05-11 17:45 UTC (permalink / raw)
To: netdev
This patch removes from net/ (but not any netfilter files)
all the unnecessary return; statements that precede the
last closing brace of void functions.
It does not remove the returns that are immediately
preceded by a label as gcc doesn't like that.
Done via:
$ grep -rP --include=*.[ch] -l "return;\n}" net/ | \
xargs perl -i -e 'local $/ ; while (<>) { s/\n[ \t\n]+return;\n}/\n}/g; print; }'

* [PATCH net-next] net/: (netfilter related) Remove unnecessary returns from void function()s
From: Joe Perches @ 2010-05-11 17:52 UTC (permalink / raw)
To: Patrick McHardy; +Cc: David S. Miller, netdev, netfilter-devel
This patch removes from net/ netfilter files
all the unnecessary return; statements that precede the
last closing brace of void functions.
It does not remove the returns that are immediately
preceded by a label as gcc doesn't like that.
Done via:
$ grep -rP --include=*.[ch] -l "return;\n}" net/ | \
xargs perl -i -e 'local $/ ; while (<>) { s/\n[ \t\n]+return;\n}/\n}/g; print; }'

This seems extremely unusual, can you tell us what kernel version you're
using and what kind of test you're running?
it almost seems that there is an off by one somewhere, what kind of
traffic is being transmitted?

* virtio: power management
From: Michael S. Tsirkin @ 2010-05-11 18:12 UTC (permalink / raw)
To: Rusty Russell; +Cc: netdev, virtualization, kvm, linux-kernel, gleb
Anyone looked at power management with virtio?
virtio-pci has callbacks to save/restore pci config
on suspend/resume, but it seems that more action,
such as restoring queue state, would be needed
for e.g. suspend to disk to work.
Rusty, any hints on the code in virtio-pci
that deals with suspend? Is it incomplete?
Thanks,

I agree that it might be usefull to have this on by default, we can't really
know if the queues are going to be setup to direct traffic to inactive slaves
until after the module is loaded and the interface is created. Setting up tc
filters to steer traffic will only occur after the interface is other wise
configured (bond needs to be created, and slaves need to be added). Perhaps
user space could tie the the setting of this variable in sysfs to tc
configuration in some way?

Two patches targeted at the next merge window affecting the ioatdma
driver (used when NET_DMA and/or ASYNC_TX_DMA+MD_RAID456 are enabled).
According to perf the split locking update improves cpu utilization by a
few percentage points.

Dave,
Another round of bits intended for 2.6.35...mostly driver updates this
time. The biggest item of note is some continued attention for rt2800
from the rt2x00 team.
Please let me know if there are problems!

* [PATCH net-next] drivers/net: Remove unnecessary returns from void function()s
From: Joe Perches @ 2010-05-11 19:30 UTC (permalink / raw)
To: netdev
This patch removes from drivers/net/ all the unnecessary
return; statements that precede the last closing brace of
void functions.
It does not remove the returns that are immediately
preceded by a label as gcc doesn't like that.
Done via:
$ grep -rP --include=*.[ch] -l "return;\n}" net/ | \
xargs perl -i -e 'local $/ ; while (<>) { s/\n[ \t\n]+return;\n}/\n}/g; print; }'
with some cleanups by hand.
Compile tested x86 allmodconfig only.
