* [PATCH] iproute2: use -fPIC in lib/
From: Andreas Henriksson @ 2009-09-21 7:47 UTC (permalink / raw)

The static libnetlink.a library is exposed to other users in Debian via the
"iproute-dev" package. Apparently people are interested in using it in their
shared libraries and would like to see the code be position independent.
Patch below makes the code under lib/ build with -fPIC.

Hi Jarek,
Good fishing !
During the night I catched the following two identical AX25_DBG messages with netconsole
sending already reported message: kernel BUG at kernel/timer.c:913! and followed by kernel
panics and the machine rebooting.

It's another high-order atomic allocation which is difficult to grant.
I didn't look closely, but is this the same type of thing - large allocation
failure during firmware loading? If so, is this during resume or is the
device being reloaded for some other reason?
I suspect that there are going to be a few of these bugs cropping up
every so often where network devices are assuming large atomic
allocations will succeed because the "only time they happen" is during
boot but these days are happening at runtime for other reasons.

Just modprobing the driver on a system running for some time.

I wouldn't go so far as calling a normal order-6 (256kB) allocation on
512MB machine with 1024MB swap a bug. Moreover such failures just never
happened before 2.6.31-rc1.
I don't know why people don't see it but for me it has a memory management
regression and reliability issue written all over it.

It's not that normal, it's an allocation that cannot sleep and cannot
reclaim. Why is something like firmware loading allocating memory like
that? Is this use of GFP_ATOMIC relatively recent or has it always been
that way?

Possibly but drivers that reload their firmware as a response to an
error condition is relatively new and loading network drivers while the
system is already up and running a long time does not strike me as
typical system behaviour.

When reverting the mentioned commit it works again.
I'm running a Debian testing distro.

Loading drivers after boot is a typical desktop/laptop behavior, please
think about hotplug (the hardware in question is an USB dongle).

Yeah, I wonder what broke things. Did the wireless stack change in
2.6.31-rc1 too? IIRC Mel ruled out page allocator changes as a suspect.

In that case, how reproducible is this problem so it can be
bisected? Basically, there are no guarantees that GFP_ATOMIC allocations
of this order will succeed although you can improve the odds by increasing
min_free_kbytes. Network drivers should never have been depending on GFP_ATOMIC
succeeding like this but the hole has been dug now.
If it's happening more frequently now than it used to then either
1. The allocations are occuring more frequently where as previously a
pool might have been reused or the memory not freed for the lifetime of
the system.
2. Something has changed in the allocator. I'm not aware of recent
changes that could cause this though in such a recent time-frame.
3. Something has changed recently with respect to reclaim. There have
been changes made recently to lumpy reclaim and that might be impacting
kswapd's efforts at keeping large contiguous regions free.
4. Hotplug events that involve driver loads are more common now than they
were previously for some reason. You mention that this is a USB dongle for
example. Was it a case before that the driver loaded early and remained
resident but only active after a hotplug event? If that was the case,
the memory would be allocated once at boot. However, if an optimisation
made recently unloads those unused drivers and re-loads them later, there
would be more order-6 allocations than they were previously and manifest
as these bug reports. Is this a possibility?
The ideal would be that network drivers not make allocations like this
in the first place by, for example, DMAing the firmware across in
page-size chunks instead of one contiguous lump :/

The thing is that the mm behavior change has been narrowed down already
over a month ago to -mm merge in 2.6.31-rc1 (as has been noted in my initial
reports), I first though that that it was -next breakage but it turned out
that it came the other way around (because -mm is not even pulled into -next
currently -- great way to set an example for other kernel maintainers BTW).
I understand that behavior change may be justified and technically correct
in itself. I also completely agree that high order allocations in certain
drivers need fixing anyway.
However there is something wrong with the big picture and the way changes
are happening. I'm not saying that I'm surprised though, especially given
the recent decline in the quality assurance and the paradigm shift that
I'm seeing (some influential top level people talking that -rc1 is fine for
testing new code now or the "new kernel new hardware" thing).
Sorry but I have no more time currently to narrow down the issue some more
(guess what, there are other kernel bugs standing in the way to bisect it
and I would have to provide some reliable way to reproduce it first) so I
see no more point in wasting people's time on this. I can certainly get by
with allocation failure here and there. Not a big deal for me personally..

Is there a reliable reproduction case for this that narrowed it down to
2.6.31-rc1? That is the window where a number of page-allocator optimisation
patches made it in. None of them should have affected the allocator from a
fragmentation perspective though.
If you have a reliable reproduction case, testing between commits
d239171e4f6efd58d7e423853056b1b6a74f1446..a1dd268cf6306565a31a48deff8bf4f6b4b105f7
would be nice, particularly if it can be bisected within that small
window rather than a full bisect of an rc1 which I know can be a major
mess.

The quality assurance comment is a bit unfair with respect to the page
allocator. There are a lot of things that can have changed that would hose
order-6 atomic allocations. Furthermore, test cases used for mm patches
would not have taken into account such allocations as being critical. Even
if it was considered, it would have been dismissed as "it makes no sense
for drivers to be doing order-6 GFP_ATOMIC" allocations.

That is somewhat unfortunate. Even testing within the window above if
possible would be very helpful if you get the chance.

* [PATCH] sky2: Set SKY2_HW_RAM_BUFFER in sky2_init
From: Mike McCormack @ 2009-09-21 14:08 UTC (permalink / raw)
To: Stephen Hemminger; +Cc: netdev
The SKY2_HW_RAM_BUFFER bit in hw->flags was checked in sky2_mac_init(),
before being set later in sky2_up().
Setting SKY2_HW_RAM_BUFFER in sky2_init() where other hw->flags are set
should avoid this problem recurring.

* [PATCH 00/13] TProxy IPv6 support 2nd round
From: Balazs Scheidler @ 2009-09-21 15:51 UTC (permalink / raw)
To: netfilter-devel, netdev
Hi,
This is the 2nd version of TProxy and by this time it is complete with UDP
and ICMP support. For those credits go to Harry Mason from Smoothwall.
Now I consider this patch complete, testers, reviews comments are very
welcome.
If no blockers show up, please consider this a merge request.
I only know of one issue and I hope it does not block merging at this time:
the socket and TPROXY modules both depend on both IPv4 and IPv6 stacks, thus
pulling in the other even if only one of the stacks are in use. Of course
if IPv6 is not configured into the kernel no such dependency is present.
I've tested the functionality of this patch-set with an automatic test
program that runs a large number of tests and covers most of the TProxy
functionality. You can find this program at:
git://git.balabit.hu/bazsi/tproxy-test.git/
I would appreciate if someone with more intimate IPv6 knowledge would review
this code, especially:
* IPv6 ICMP packet parsing
* the way the default local IP address is found
(especially returning a pointer pointing to &inet6_ifaddr->addr outside RCU section)
This patchset is based on an older tree of Linus, I don't expect any
problems with net-next, but please let me know if I have to rebase/retest.
The userspace portion of the tproxy functionality comes in a followup
patch-set.
In addition to IPv6 support there are 3 patches in this series:
1) a fix for properly handling TIME_WAIT connections
2) a fix for the default value of --on-ip
3) and an optional change in ipv6_pinfo structure
While the last is completely independent of TProxy and is optional, the
first two are quite important fixes. Although they are independent of this
submission, they are the first and last patches of the series, so they can
be reviewed independently :)
And again, please apply.
Balazs Scheidler (13):
TProxy: kick out TIME_WAIT sockets in case a new connection comes in
with the same tuple
TProxy: add lookup type checks for UDP in nf_tproxy_get_sock_v4()
TProxy: move dst_cookie to the first cacheline in ipv6_pinfo
TProxy: split off ipv6 defragmentation to a separate module
TProxy: added const specifiers to udp lookup functions
TProxy: added udp6_lib_lookup function
TProxy: implement IPv6 "local" routing type
TProxy: added tproxy sockopt interface in the IPV6 layer
TProxy: allow non-local binds of IPv6 sockets if IP_TRANSPARENT is
enabled
TProxy: added IPv6 socket lookup function to nf_tproxy_core
TProxy: added IPv6 support to the TPROXY target
TProxy: added IPv6 support to the socket match
TProxy: use the interface primary IP address as a default value for
--on-ip

More importantly, when virtualizations is used with multi-queue NIC's the virtio-net
NIC is a single CPU bottleneck. The virtio-net NIC should preserve the parallelism (lock
free) using multiple receive/transmit queues. The number of queues should equal the
number of CPUs.

* [PATCH 13/13] TProxy: use the interface primary IP address as a default value for --on-ip
From: Balazs Scheidler @ 2009-09-21 14:46 UTC (permalink / raw)
To: netfilter-devel, netdev
The REDIRECT target and the older TProxy versions used the primary address
of the incoming interface as the default value of the --on-ip parameter.
This was unintentionally changed during the initial TProxy submission and
caused confusion among users.
This is implemented for both IPv4 and IPv6.

From: Balazs Scheidler @ 2009-08-23 9:19 UTC (permalink / raw)
To: netfilter-devel, netdev
Just like with IPv4, we need access to the UDP hash table to look up local
sockets, but instead of exporting the global udp_table, export a lookup
function.

* [PATCH 0/2] TProxy IPv6 support, 2nd round, iptables portion
From: Balazs Scheidler @ 2009-09-21 15:43 UTC (permalink / raw)
To: netfilter-devel, netdev
This series accompanies the TProxy IPv6 2nd round patches and adds userspace
support for the TPROXY target and the socket match.
Since the last post, I've fixed the xt_socket.h header file which contained
an obsolete struct declaration for the xt_socket matchinfo, but this is not
incompatible with the previous patch, thus you don't need to recompile
iptables if you already have the old binaries.

Yup, multiqueue virtio is on todo list ;-)

Update: i've further investigated it and this bug was caused by a
scheduler bug introduced in this merge window, which got fixed in:
3f04e8c: sched: Re-add lost cpu_allowed check to sched_fair.c::select_task_rq_fair()
This bug caused CPU affinities to not work in essence - breaking kthread
per-cpu assumptions in net/core/pktgen.c.
I've confirmed this by re-enabling pktgen in my tests and the crash has
no reappeared.
Thanks,
Ingo
