Subject: [netfilter bug] BUG: using smp_processor_id() in preemptible [00000000] code: ssh/9115, caller is ipt_do_table+0xc8/0x559

Not sure whether this bug has been reported before (a quick subject
search on netdev and lkml suggests that it's not):

i switched over -tip to latest -git an hour ago (it was on a v2.6.29
base before that), and one of my testboxes started emitting lots of
these warnings:

Config attached.

( Can send more environmental info if needed. Stock distro, no
networking specials anywhere. NOTE: the config is randconfig
derived so unusual/unexpected config combinations may occur in it. )

The upstream base for -tip is v2.6.29-7100-g833bb30.

Thanks,

Ingo

Subject: [PATCH] netfilter: iptables: lock free counters, PREEMPT_RCU=y fix

Impact: fix log spam under CONFIG_DEBUG_PREEMPT=y

This recent commit:

7845447: netfilter: iptables: lock free counters

Converted a couple of netfilter codepaths from read_lock() critical
sections to lockless rcu_read_lock(). What it forgot about is that
under CONFIG_PREEMPT=y and CONFIG_PREEMPT_RCU=y these sections can
be preempted.

Under CONFIG_DEBUG_PREEMPT=y this produces such warnings:

BUG: using smp_processor_id() in preemptible [00000000] code: ssh/9114

Since it appears that the tables are RCU freed, and there are no
non-preempt assumptions in the code, the using of
raw_smp_processor_id() is safe.

[ I also audited all of net/netfilter/*.c for smp_processor_id() use,
and fixed all places that used them unsafely. ]

Hi Ingo

David put into its tree fix for that a few hours ago

commit fa9a86ddc8ecd2830a5e773facc250f110300ae7

(netfilter: iptables: lock free counters) forgot to disable BH
in arpt_do_table(), ipt_do_table() and ip6t_do_table()

Use rcu_read_lock_bh() instead of rcu_read_lock() cures the problem.

Small request: it's useful to plain-text include such commits in
such email replies - if the patch is not too large. http is not very
helpful to reply to specifics and it's not very useful when i want
toapply it either. I now have to go hunting for the latest tree :)

ok, got your fix (attached below), thanks Eric for the pointer.

But i think my fix might be slightly better, because it does not
manipulate the preempt counter and leaves preemption enabled.

There's no BH context worries since this code did not seem to have
BH protection before either. (it used a plain read_lock(), not
read_lock_bh(), AFAICS)

I dont see any preemption worries either. I must be missing
something :)

With my patch applied the box appears to boot fine and there's no
syslog flood either. (no heavy testing done though)

Ingo

NAK. The rcu_read_lock() needs to be rcu_read_lock_bh() otherwise RCU
could corrupt the referenceses.

Indeed - somehow i missed that it originally used read_lock_bh().

I was wondering about that already: how could get_entry() and
nf-iterator work without worrying about softnet-rx processing, it
just looked too involved to be trivially preemptible.

Thanks, i'll use Eric's patch.

as per the other mail - what i missed was that the old code _did_
use read_lock_bh(), which did not get carried over into the
rcu_read_lock().

So this fix affects basically all things netfilter, not just
rcu-preempt - a plain rcu_read_lock() doesnt protect against BH
context interaction.

Strangely enough, the original motivation for rcu_read_lock_bh() does not
apply to -rt kernels. The problem was that denial-of-service workloads
could apply such a heavy interrupt load to a given CPU that it never
got back to process-level execution, thus never passing through any
quiescent states.

So rcu-bh has softirq-level quiescent states, solving that problem,
but by disabling softirq (and thus preemption) across the read-side
critical sections.

But -rt has every point in the code not covered by rcu_read_lock()
as a quiescent state, so should not be vulnerable to that particular
denial-of-service attack. But rcu-bh has the additional semantic of
excluding BH execution while under rcu_read_lock_bh(), which appears
to be used in this case, and probably others as well.

Interesting corner we have painted ourselves into here...
