* [PATCH 21/24] IPVS: Minimise ip_vs_leave when CONFIG_SYSCTL is undefined
From: Simon Horman @ 2011-03-14 9:06 UTC (permalink / raw)
To: netdev, netfilter-devel, netfilter, lvs-devel

In-Reply-To: <1300093596-3824-1-git-send-email-horms@verge.net.au>
Much of ip_vs_leave() is unnecessary if CONFIG_SYSCTL is undefined.
I tried an approach of breaking the now #ifdef'ed portions out
into a separate function. However this appeared to grow the
compiled code on x86_64 by about 200 bytes in the case where
CONFIG_SYSCTL is defined. So I have gone with the simpler though
less elegant #ifdef'ed solution for now.

* [PATCH 04/24] Fix variable assignment in ip_vs_notrack
From: Simon Horman @ 2011-03-14 9:06 UTC (permalink / raw)
To: netdev, netfilter-devel, netfilter, lvs-devel

In-Reply-To: <1300093596-3824-1-git-send-email-horms@verge.net.au>
From: Jesper Juhl <jj@chaosbits.net>
There's no sense to 'ct = ct = ' in ip_vs_notrack(). Just assign
nf_ct_get()'s return value directly to the pointer variable 'ct' once.

conn_count and tcp_app_lock, udp_app_lock, sctp_app_lock
are used when packet creates new connection, probably on the
same time depending on the protocol in packet. May be conn_count
better to be before tcp_apps, far away from some sysctl vars
that are mostly read?
For tot_stats: cpustats ptr is always read,
other fields in tot_stats are updated from the 2-second
timer. May be it is better just to move tot_stats before
est_list, it is written at the same time?

Nice, so this is a generic way of getting out gratuitous arps.
Can it be used by drivers (macvlan) on top of bonding.
Bonding is sending the BOND_FAILOVER event that could be mapped
to NOTIFY_PEERS in the higher level devices.
And bonding is implementing its own grat arps functions, maybe it could
be broken out to use the NOTIFY_PEERS instead.
And what about IPv6, would it be ok to implement an unsolicited NA on
the event?
I will happily implement the above, if anyone thinks it's worth it?

Indeed you are right. As long as it is only a mask and only

Yeah, powerpc alone compiles with GENERIC_HARDIRQS_NO_DEPRECATED as it
does not have that notify commit.
If you add net which has that notify commit, but not the fix it
breaks. I wonder whether Dave should pick that fix into net.

Plain 2.6.37 did not work at all. Received packets with vlan tag did not make
it to the vlan interface but ended on the native ethernet interface iirc.

No, this is the host in vlan2.
The packet contains the vlan tag with vid 0. It should not. The host discards
it as it does not have a vlan interface with vid 0.

The tag itself is valid. But it should not be there as it comes from
a native ethernet port.
> Where was this trace captured?
This trace was captured on the host in vlan2.
Ok, let me explain step by step:
* Host sends icmp echo request (172.16.0.21 -> 192.168.100.3) to router
172.16.0.1, the packet is untagged.
* Switch receives the packet on native interface with vid 2, tags it and sends
it to the trunk)
* Netbook receives the packet from trunk, untags it an queues it to vlan
interface 2.
* Netbook nats the packet (192.168.x.140 > 192.168.100.3), tags it with vlan
2 and sends it to the trunk.
* Switch receives the packet from trunk, untags it and sends it to native
interface with vlan 1.
* The packet and its answer (192.168.100.3 -> 192.168.x.140) make their way
through the network.
* Switch receives the icmp echo reply on native interface with vlan 1, tags
it and sends it to the trunk
* Netbook receives the packet from trunk, untags it an queues it to vlan
interface 1.
* Netbooks restores the original addresses from nat (192.168.100.3 ->
172.16.0.21), _tags_it_with_vlan_0_, tags it with vlan 2 and sends it to the
trunk.
* Switch receives packet from trunk, untags it (the tag with vid 2) and sends
it to native interface with vid 2.
* Host receives the packet and discards it as it still contains a vlan tag
with vid 0.

This is the same kind of sillyness that started getting OMAP into problems
with the clk API. Just do this instead:
bp->pclk = clk_get(&pdev->dev, "pclk");
if (IS_ERR(bp->pclk)) {
dev_err(&pdev->dev, "failed to get pclk\n");
goto err_out_free_dev;
}
bp->hclk = clk_get(&pdev->dev, "hclk");
if (IS_ERR(bp->hclk)) {
dev_err(&pdev->dev, "failed to get hclk\n");
goto err_out_put_pclk;
}
clk_enable(bp->pclk);
clk_enable(bp->hclk);
And then require _all_ platforms using this driver to provide a pclk and
a hclk for this device, whether they exist in the SoC or not. Where they
don't, provide dummy clocks for it.
This probably means you end up with _less_ bloat overall because you're
not having to build the above code. You've less lines of source code to
maintain. You have a simplified dirver with consistent requirements
across all platforms. You don't need to read the version register, and
you don't need macb_is_at91() and macb_is_avr32().
With clkdev it's _cheap_ to provide these dummy clocks once you have one
dummy clock already in place.

The moderation is in place to avoid gigantic segment bursts, which could cause
unnecessary pressure on buffers. In my eyes it's already suboptimal that the
moderation is weakened in the presence of (detected) reordering, let alone
removing it completely.
More importantly, the prior ssthresh is restored and not affected by
moderation. This means, if moderation reduces cwnd to a small value, then cwnd
< ssthresh and TCP will quickly slow-start back to the previous state, without
sending a big burst of segments.
Also, you intended to remove cwnd moderation only from an undo during
recovery, but I think your patch also removes cwnd moderation when the undo is
caused by D-SACK, i.e. most likely after recovery already ended.

Hi,
I agree with Russell's comments about providing a fake hclk to remove
the conditional clock stuff. I was planning on posting the patch below
in my next spin of the gem support patches which also renames macb_clk
to pclk to be consistent with avr32 and enables us to remove all of the
conditional clock stuff.

I can't convince myself that this is safe and correct. From the Cadence
GEM spec:
31:16 Module identification number - for the GEM, this
value is fixed at 0x0002.
15:0 Module revision - fixed byte value specific to the
revision of the design which is incremented after
each release of the IP.
I don't have access to the MACB spec, but it seems that 31:16 are
defined by Cadence so there could well be other chips with a module ID
of 0x0001 that aren't avr32.
We can certainly use this to tell us if we are GEM/MACB but if we need
to know if we are AT91/AVR32 for the RMII/MII USRIO stuff, then couldn't
we just keep the #ifdef CONFIG_ARCH_AT91 and factor that out into a
macb_set_usrio() type method?
