I don't want to jump the gun on the analysis but it just might
be the packet sharing fixes Herbert put in a short time ago.
What you could do is go back to say rc2 and see if you still get
the panics, then bisect from there to narrow it down.
If rc2 still gives the panic, it's something else, perhaps device
specific.

* [PATCH] net: fix kernel_accept() error path
From: Tony Battersby @ 2007-10-04 20:20 UTC (permalink / raw)

If accept() returns an error, kernel_accept() releases the new socket
but passes a pointer to the released socket back to the caller. Make it
pass back NULL instead.

* [PATCH 2.6.23-rc9] [TCP]: Fix fastpath_cnt_hint when GSO skb is partially ACKed
From: Ilpo Järvinen @ 2007-10-04 20:38 UTC (permalink / raw)
To: David Miller; +Cc: Netdev, Cedric Le Goater
[-- Attachment #1: Type: TEXT/PLAIN, Size: 1585 bytes --]
When only GSO skb was partially ACKed, no hints are reset,
therefore fastpath_cnt_hint must be tweaked too or else it can
corrupt fackets_out. The corruption to occur, one must have
non-trivial ACK/SACK sequence, so this bug is not very often
that harmful. There's a fackets_out state reset in TCP because
fackets_out is known to be inaccurate and that fixes the issue
eventually anyway.
In case there was also at least one skb that got fully ACKed,
the fastpath_skb_hint is set to NULL which causes a recount for
fastpath_cnt_hint (the old value won't be accessed anymore),
thus it can safely be decremented without additional checking.

Dave, here's the same fix to upcoming 2.6.23, hopefully it can
make it in time. Probably minor enough to skip stable-2.6.22,
especially since 2.6.23 is soooo close :-), but I leave that
up to you.

Thanks a lot, the bug itself seems to occur far more common than I
thought... It just very rarely manifests in significant behavior (requires
non-trivial ACK/SACK pattern to occur). This same bug is present in the
soon to be released 2.6.23 and in stable too though it's nearly impossible
to ever see that by human eye and there's a silent fackets_out "fix up" in
place due to known (and intentional) fackets_out inaccuracy (and nobody is
really looking that large number of TCP traces)...
The fix below, you can test it with the debug patch quite easily, all
those messages should of course vanish :-). In case you want to
test, please mix those three patches (fixes a real bug too), this one and
the debug patch together...
Dave should apply both the three patch series fix and this one as well to
net-2.6.24 (Dave, in case you want me to resubmit, just ask... :-)). I'll
send one against .23-rc9 soon after this (sadly enough, it will cause a
conflict...).

i.
[PATCH net-2.6.24] [TCP]: Fix fastpath_cnt_hint when GSO skb is partially ACKed
I used to be under impression that all hints are cleared in
clean_rtx_queue whenever cumulative ACKs occur. Yet, when only
GSO skb was partially ACKed, no hints were reset, therefore
fastpath_cnt_hint must be tweaked too or else it can corrupt
fackets_out. In case there was also a skb that got fully ACKed,
the fastpath_skb_hint is set to NULL which causes a recount for
fastpath_cnt_hint (the old value won't be accessed anymore),
thus it can safely be decremented without additional checking.
Reported by Cedric Le Goater <clg@fr.ibm.com>, two other bugs
have been already found and patched due to that report, and
third one (unrelated to this fix) is under evaluation
currently :-)...

* wireless-dev dead, long live wireless-2.6
From: John W. Linville @ 2007-10-04 18:47 UTC (permalink / raw)
To: linux-wireless; +Cc: netdev
Greetings,
This message is perhaps a few days late -- better late than never. :-)
The big news is that wireless-dev is now dead, defunct, kaput.
Please discontinue any use of wireless-dev or any of its clones.
If you need access to the contents of that tree for historical
purposes, please see the snapshot in my wireless-legacy tree:
git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-legacy.git wireless-dev-2007-09-24
I will remove the wireless-dev repository from kernel.org shortly
after sending this message. From now on, please use the 'everything'
branch of wireless-2.6 as the base for new wireless development.
git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-2.6.git everything
Please note that this branch is subject to rebasing. In general
it will be rebased whenever Linus christens a new -rcX release,
sometimes more often than that. "git rebase" and "git cherry-pick"
are your friends.
As always, patches based on a vanilla tree from Linus (or the
'master' branch of wireless-2.6) are acceptable or even preferable
for those patches which do not depend on other pathes already in the
wireless-2.6 tree. Otherwise, base your patches on the 'everything'
branch as described above.
Most of the other branches in wireless-2.6 are only there for
administrative purposes. You can and should ignore them, with possibly
a couple of exceptions.
One of two possible branches of interest to some is the
'mac80211-attic' branch. This branch mostly contains patches
supporting hostap functionality for mac80211. These patches will
not be merged as-is due to unsettled user interface issues. I have
preserved them on this branch solely as a courtesy to those who need
this functionality. I expect for this functionality to be replaced
RSN by work underway from Johannes Berg.
The other possible branch of interest is the 'mac80211-dungeon'
branch. This branch contains several patches for 802.11n and other
advanced functionality (e.g. DLS). However, the mac80211 component
maintainers have strongly objected to these patches for a variety
of reasons. The various parties are still working to resolve the
issues preventing these patches from being merged. In the meantime
I have preserved these patches on this branch as a courtesy to those
who need them as well.
I hope this message clears-up some questions that people have been
expressing. If there are other questions, please feel free to ask.
Thanks!
John

Falling back on bloat as an argument against a BUG_ON in a
configuration path seems a bit weak. :-)
Programming with assertions (and BUG_ON is a form of that) is
generally a good practice. Almost any book or other source on
good programming practices will agree. Yes, it can be overdone.
But I don't really think that is the case here, since the check is
relatively inexpensive and the consequence should it ever *somehow*
happen could be a something wierd (crash, corruption, etc) w/o any
other indication of what occured.
Anyway, the point is probably moot in this case if there is no great
objection to the alternative patch I proposed.

* [PATCH] ieee80211_if_set_type: make check for master dev more explicit
From: John W. Linville @ 2007-10-04 18:09 UTC (permalink / raw)
To: Daniel Drake; +Cc: johannes, netdev, linux-wireless
In-Reply-To: <20071004113343.552139D502B@zog.reactivated.net>
Problem description by Daniel Drake <dsd@gentoo.org>:
"This sequence of events causes loss of connectivity:
<plug in>
<associate as normal in managed mode>
ifconfig eth7 down
iwconfig eth7 mode monitor
ifconfig eth7 up
ifconfig eth7 down
iwconfig eth7 mode managed
<associate as normal>
At this point you are associated but TX does not work. This is because
the eth7 hard_start_xmit is still ieee80211_monitor_start_xmit."
The problem is caused by ieee80211_if_set_type checking for a non-zero
hard_start_xmit pointer value in order to avoid changing that value for
master devices. The fix is to make that check more explicitly linked to
master devices rather than simply checking if the value has been
previously set.

I think I'd rather fix this by making the check in

I was able to narrow this down a bit - the problem can be reproduced with
the ne2k-pci driver alone, sky2 is not needed.
Powering off isn't necessary, either.
Hardware preparation:
- eth0: Compex ReadyLink 2000 (BNC+TP), ne2k-pci driver,
network cable disconnected
How to reproduce the problem:
brctl addbr br0
brctl addif br0 eth0
ifconfig eth0 0 up
ifconfig br0 192.168.1.17 up
sync
find / >/dev/null &
ping -b 192.168.1.255
This will lock up my system, usually within a few seconds.
Some additional information:
- I could not reproduce the problem when using eth0 directly,
without a bridge.
- Booting with "maxcpus=1" does not help, the problem remains.
My system doesn't boot with "nosmp", otherwise I would have
tried this too.

I kinda agree, but the hack in 50e1f4d76a9d45c940733f05ccd42c5bbe6ca132
which caused this was is hack too. Somebody really need to rewrite the
whole interface handling, it's a total mess with the master being
specially treated but initialised by the same functions etc. I think we
should start having a IEEE80211_IF_TYPE_MASTER for this, maybe then
things will fall into place nicer.

* Vague maybe ppp-related panic report for 2.6.23-rc9
From: Roland Dreier @ 2007-10-04 18:12 UTC (permalink / raw)
To: linux-kernel, netdev
I'm running 2.6.23-rc9 on my laptop, and when in a coffee shop I use
a Verizon EVDO card to get network access. This is a kyocera device
that looks like a serial adapter behind an ohci usb controller, and
uses the airprime driver (for usb device 0c88:17da). The actual IP
networking is ppp over that serial adapter.
The connection is slightly flaky (I blame this on the Verizon
coverage), so I end up restarting things every so often. The point of
this email (at last) is that I've just seen my second panic (only
info: blinking caps lock led, since I've been in X) that seems
correlated to stopping/restarting pppd.
Sorry for the lack of detail -- I've just switched to running in the
console so if I can provoke the crash again I'll get a little more
info. I just wanted to mention this in case someone has seen
something similar or has any good ideas about how to capture debugging
output on a laptop (when I'm not home and have no other boxes handy).

* netconsole problems
From: Tina Yang @ 2007-10-04 17:59 UTC (permalink / raw)
To: Matt Mackall, netdev
We recently run into a few problems with netconsole
in at least 2.6.9, 2.6.18 and 2.6.23. It either panicked
at netdevice.h:890 or hung the system, and sometimes depending
on which NIC we are using, the following console message,
e1000:
"e1000: eth0: e1000_clean_tx_irq: Detected Tx Unit Hang"
tg3:
"NETDEV WATCHDOG: eth4: transmit timed out"
"tg3: eth4: transmit timed out, resetting"
The postmortem vmcore analysis indicated race between normal
network stack (net_rx_action) and netpoll, and disabling the
following code segment cures all the problems.
netpoll.c
178 /* Process pending work on NIC */
179 np->dev->poll_controller(np->dev);
180 if (np->dev->poll)
181 poll_napi(np);
Big or small, there seems to be several race windows in the code,
and fixing them probably has consequence on overall system performance.
Maybe this code should only run when the machine is single-threaded ?
Suggestions ? Thanks.

Yes, run it. And add links to the bugs, or at least a generic
URL at the top so people can easily find them:
http://bugzilla.kernel.org/show_bug.cgi?id=<number>
NOTE:
In Firefox you can create "keyword" bookmarks:
Name: Kernel Bug
Location: http://bugzilla.kernel.org/show_bug.cgi?id=%s

Then you can type "bz <number>" in the address bar to go right to

No really, this bug will never happen. This is function is merely a helper
function which is called from interface removal code (where the interface
*has* to be down) or from changing the interface type (which ensures that the
interface is down first). There are an unlimited number of bugs which Should
Never Happen. That doesn't mean we should start adding BUG_ONs for every
single one of them. That gives some sort of protection against cosmic rays
flipping bits, but down here on earth, it's bloat.

Go look at the bug report on bugzilla and do what you can. No one
is going to complain if you can fix it :-) Even if you can't fix
it adding more information, test cases, etc would be helpful

This is all under RTNL and the pointer is only modified while the interface is
down.

Stephen,
Are there any bugs that I can look into?
