Since SFQ is not exactly simple and I needed something like this
myself, I followed Paul's suggestion and added a new scheduler
(DRR) for this with more flexible limits.
I'll rediff against net-2.6.26 within the next days and send
a final version for review (anyone interested is welcome to
already review this version of course :).

Hi,
This patch removes definition of netlbl_cfg_cipsov4_del() method in
netlabel/netlabel_kapi.c and in include/net/netlabel.h as it is not used.

That does the trick -- but are we using u_int32_t elsewhere in
user-visible headers? Does it work there? How?

It's in busybox 1.9.1. Just including <netinet/in.h> seems to be
sufficient to make it happy again. I wonder if netfilter.h should
include that for itself?

Here you go.
Just to be clear, the initial lockdep report was with non-bh locks.
Yesterday's report was with _bh locks and the sk_dst_get() changes. This
(older) report is with _bh locks but without the sk_dst_get() changes.

Its used in nearly every ip_tables header file. Those are most likely
not included by glibc and iptables includes sys/types.h. Besides
iptables I'm only aware of a perl module that uses these files,
which is probably also including sys/types.h.

That would break iptables compilation, which already includes
linux/in.h in some files. I guess the best fix for now is to
include netinet/in.h in busybox and long-term clean this up
properly.

Yes, I'll send it to -stable as soon as it hits upstream.

[NET]: Messed multicast lists after dev_mc_sync/unsync
Commit a0a400d79e3dd7843e7e81baa3ef2957bdc292d0 from you
introduced a new field "da_synced" to struct dev_addr_list that is
not properly initialized to 0. So when any of the current users (8021q,
macvlan, mac80211) calls dev_mc_sync/unsync they mess the address
list for both devices.
The attached patch fixed it for me and avoid future problems.

Ok, so after a long discussion with Denis about this patch, I will
change the ipv6 code to share the neigh->parms. It is not a problem.
Having the behavior of the neighbour subsystem per namespace is not a
must-have.

This was added for use by Smack (and any other LSMs which want to
configure NetLabel directly) and since this is an area that is
undergoing a lot of churn at this point I'd prefer if this function was
left in place for the time being.
At a later date if this function is still unused, I'll gladly ack it's
removal or do so myself.

This patch does appear to fix the data corruption (tested with
2.6.24.2). However, it results in performance problems with the iSCSI
application that I am trying to run on this machine.
The test program that I described in the previous message still gets
good performance in both directions. "iperf -r" gets good performance
in both directions (940 Mbits/s or 117 MB/s). However, my target-mode
iSCSI application (which obviously generates rx/tx traffic patterns more
complicated than the synthetic tests) gets very poor performance in one
direction but good performance in the other direction. iSCSI
performance drops to 6 - 15 MB/s when the 3Com NIC is doing heavy rx
with light tx, but remains at a decent 115 MB/s when the 3Com NIC is
doing heavy tx with light rx. When I revert Herbert's patch instead of
applying the patch above, I get 115 MB/s in both cases. (With a stock
unpatched kernel, the test fails almost immediately because the iSCSI
control PDUs are corrupted, causing the TCP connection to be dropped.)
The SysKonnect NIC that does not exhibit this problem has a chip that
says "BCM5411KQM" "TT0128 P2Q" and "56975E".

* [net-2.6][DRIVER][VETH] fix dev refcount race
From: Daniel Lezcano @ 2008-02-19 16:18 UTC (permalink / raw)

Subject: veth fix dev refcount race
From: Daniel Lezcano <dlezcano@fr.ibm.com>
When deleting the veth driver, veth_close calls netif_carrier_off
for the two extremities of the network device. netif_carrier_off on
the peer device will fire an event and hold a reference on the peer
device. Just after, the peer is unregistered taking the rtnl_lock while
the linkwatch_event is scheduled. If __linkwatch_run_queue does not
occurs before the unregistering, unregister_netdevice will wait for
the dev refcount to reach zero holding the rtnl_lock and linkwatch_event
will wait for the rtnl_lock and hold the dev refcount.

Brr... AFAIS the unregister process waits for refcount without
the rtnl_lock. The run-todo was invented for this. No?

* [PATCH][SCTP]: Pick up an orphaned sctp_sockets_allocated counter.
From: Pavel Emelyanov @ 2008-02-19 16:36 UTC (permalink / raw)
To: David Miller, Vlad Yasevich; +Cc: Linux Netdev List, lksctp-developers
This counter is currently write-only.
Drawing an analogy with the similar tcp counter, I think
that this one should be pointed by the sockets_allocated
members of sctp_prot and sctpv6_prot.
Or should it be instead removed at all?

my first thought after I read this e-mail is that the tx-hang message is just a
symptom of your system not responding or being spinlocked all the time. These TX
hang issues normally completely do not interfere with normal system operation and
unless you have continuous TX resets you would be able to logon perfectly fine.
I think you might have hit another kernel bug here... perhaps even unionfs/fuse
related and that certainly looks plausible from your problem description.
looking at the changelog for 2.6.22.16->2.6.22.18 I can't see anything relevant
(see
http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.22.y.git;a=shortlog),
but there are definately no e1000 driver changes in that range anyway.
I don't suppose you can do a git-bisect? that would certainly help. I don't think
we can rule out anything just yet here.
At least try to revert some of your systems to the previous kernel version and see
if the problem goes away...

* [PATCH] [2.6.25-rc2] igb: Fix panic with NICs with 1000BASE-SX PHY
From: Andy Gospodarek @ 2008-02-19 17:46 UTC (permalink / raw)
To: auke-jan.h.kok, jeff, davem; +Cc: netdev
From: Bill Hayes <bill.hayes@hp.com>
Auke, Jeff and David,
This patch eliminates a kernel panic with the igb driver in 2.6.25-rc2 when
running on a Intel 82575 Ethernet controller with a 1000BASE-SX PHY. The
panic does not happen with the 1000BASE-T PHY, only with a SX connection.

can't be, I personally removed that code.
for MTU > 1500 e1000e uses a plain normal sized SKB. for anything bigger e1000e
uses pages.
so I don't see how this bug could still be showing up for e1000e at all. The large
skb receive code is all gone (literally, removed).
*please* rmmod e1000; modprobe e1000e and show the dumps again so we know for sure
that we're not looking at e1000 dumps.
short fix: increase ring size for e1000 with `modprobe e1000 RxDescriptors=4096`
(or use ethtool) and `echo -n 8192 > /proc/sys/vm/min_free_kbytes` or something
like that.
what nic hardware is this on? lspci?

Perhaps I should clarify. I don't see a way to implement the additional
syncookie enhancements without storing an offset in some type of
per-socket structure. Given that, is it still deemed too high of a cost?
Is enhancing syncookies not deemed important enough to warrant the
additional 4 bytes? What if there was an additional config variable to
support arbitrary/random tcp timestamps, and then syncookies only used
the additional options when that setting was chosen? Is there some
possiblity I'm missing that could get this feature in a form suitable
for inclusion? Thanks.

* [PATCH] igb: Fix panic with NICs with 1000BASE-SX PHY
From: Auke Kok @ 2008-02-19 18:24 UTC (permalink / raw)
To: jeff; +Cc: netdev, e1000-devel, bill.hayes, andy
From: Bill Hayes <bill.hayes@hp.com>
This patch eliminates a kernel panic with the igb driver in 2.6.25-rc2 when
running on a Intel 82575 Ethernet controller with a 1000BASE-SX PHY. The
panic does not happen with the 1000BASE-T PHY, only with a SX connection.

That's strange. The patch should only affect TX performance slightly
since we are just turning off SG for TX. Please take an ethereal trace
to see what's happening and compare with a good trace.

I think this is the 5700, but please send me the tg3 output that
identifies the chip and the revision. Something like this:

* [RESEND/patch 2.6.25-rc2-git] net/enc28j60: low power mode
From: David Brownell @ 2008-02-19 20:54 UTC (permalink / raw)
To: netdev; +Cc: Claudio Lanconelli
In-Reply-To: <47AAE7CD.9050801@eptar.com>
Keep enc28j60 chips in low-power mode when they're not in use.
At typically 120 mA, these chips run hot even when idle; this
low power mode cuts that power usage by a factor of around 100.
This version provides a generic routine to poll a register until
its masked value equals some value ... e.g. bit set or cleared.
It's basically what the previous wait_phy_ready() did, but this
version is generalized to support the handshaking needed to
enter and exit low power mode.
