* Re: 2.6.24-rc5-mm1: cat /proc/net/packet -> oops

Hello,
As one of usual tests I run the following script:
for i in `find /proc -type f`; do
echo -n "cat $i > /dev/null ... ";
cat $i > /dev/null;
echo "done";
done
This time the culprit is /proc/net/packet. cat process gets killed
$ cat /proc/net/packet
Segmentation fault
and lost in lots of messages from the script but for some reason there is no
info in syslog (why?). I could capture the oops only when issued sysrq-7
or grater. That's why I didn't catch the oops earlier.
I found it because the bug makes my sparc64 box need a hardware reset most of the
time it happens and produces oops 2 screens long. x86 kills the cat process but
system is still usable and running fine. Bisection points to:
git-ubi.patch
GOOD
#
git-net.patch
BAD
ipsec-fix-reversed-icmp6-policy-check.patch
but this seems to be far from precise :)
$ grep ^commit git-net.patch | wc -l
361
Not sure if this is important but when bisecting the mm tree the oops got shorter
at some point so maybe some other patch is also involved. This one is from x86:

Did it change all occurrences of read_lock(&bond->lock) to
read_lock_bh? If so I better look at the lockdep output again.

Heh, my brain must have blocked me from seeing it because it's
too hard :)
Let's fix it the stupid way first and I'll do a local_t conversion
later.
[SNMP]: Fix SNMP counters with PREEMPT
The SNMP macros use raw_smp_processor_id() in process context
which is illegal because the process may be preempted and then
migrated to another CPU.
This patch makes it use get_cpu/put_cpu to disable preemption.

Unfortunately that doesn't work because we can then have two
CPUs trying to update the same counter which may corrupt it.
However, an optimisation is indeed possible with some work.
If we can get the address of the per-cpu counter against
some sort of a per-cpu base pointer, e.g., %gs on x86, then
we can do
incq %gs:(%rax)
where %rax would be the offset with %gs as the base. This would
obviate the need for the CPU ID and therefore avoid disabling
preemption.
Hmm, wasn't Christoph working on something like that?
Cheers,

I suspect namespace borkage. But just because you pin-pointed
my patch I'll try to track it down :)

I can reproduce this now. I suspect it's to do with the namespace
work. I'll let you know when I have digged further.

Not all of them in the bonding code, but all two of them in the small patch.

OK, we need to change all of the ones that may be called from
process context with BH on.

Surprise surprise. The namespace seq patch missed two spots in
AF_PACKET.
[PACKET]: Fix /proc/net/packet crash due to bogus private pointer
The seq_open_net patch changed the meaning of seq->private.
Unfortunately it missed two spots in AF_PACKET, which still
used the old way of dereferencing seq->private, thus causing
weird and wonderful crashes when reading /proc/net/packet.
This patch fixes them.

Right. As I surmised, networking is passing garbage into lockdep and
lockdep didn't like it.

* Please pull 'upstream-jgarzik' branch of wireless-2.6
From: John W. Linville @ 2007-12-16 4:34 UTC (permalink / raw)
To: jeff; +Cc: netdev, linux-wireless
[-- Attachment #1: Type: text/plain, Size: 9005 bytes --]
Jeff,
Some more patches intended for 2.6.25... There are a bunch of libertas
patches in there, as well as some iwlwifi cleanups from the last merge
and a couple of b43 fixes resulting from a regression in an earlier
patch already queued in netdev-2.6#upstream.
Let me know if there are any problems!
Thanks,
John

This is not what Herbert and I meant with our suggestion.
We meant to convert all of UDP and datagram handling to lock
sockets precisely like TCP does, by calling lock_sock()
on entry to functions like udp_recvmsg() and release_sock()
on exit from those functions.
Then in the packet input processing, a sequence, just like
TCP, such as:
bh_lock_sock_nested(sk);
if (!sock_owned_by_user(sk)) {
udp_do_rcv(sk, skb);
} else
sk_add_backlog(sk, skb);
Then a suitably defined ->backlog_rcv is hooked up for these
protocols as well.
Again, use TCP as a guide.
There is much more work involved to implement this properly,
and make the accounting code sharable with TCP, than the
simplistic and minimal spin lock code you added here.
Please do this correctly, thank you.

I disagree, I have yet to see a legitimate case where doing a trylock
on a mutex lock didn't turn out to be a bug when performed in an
atomic context.
This is particularly true in the networking, the bonding driver
has provided some excellent examples over the years :-)

I agree, and I see nothing wrong with Eric's patch and it

Ok, same here...
Such situations (ASSERT_RTNL() in atomic context) have always
been bugs though, and that continues to be true and I think
the check should be added somehow.

* [PATCH] SCTP: Flush fragment queue when exiting partial delivery
From: Vlad Yasevich @ 2007-12-16 7:08 UTC (permalink / raw)
To: netdev; +Cc: lksctp-developers, Vlad Yasevich
At the end of partial delivery, we may have complete messages
sitting on the fragment queue. These messages are stuck there
until a new fragment arrives. This can comletely stall a
given association. When clearing partial delivery state, flush
any complete messages from the fragment queue and send them on
their way up.

* [PATCH 2.6.25] SCTP: Use crc32c library for checksum calculations.
From: Vlad Yasevich @ 2007-12-16 7:10 UTC (permalink / raw)
To: netdev; +Cc: lksctp-developers, Vlad Yasevich
The crc32c library used an identical table and algorithm
as SCTP. Switch to using the library instead of carrying
our own table. Using crypto layer proved to have too
much overhead compared to using the library directly.

OK once I've fixed the set_multicast path I'll do an audit of
the existing ASSERT_RTNL users and then add the might_sleep
check.

Jamal's going to hate me but setkey(8) already uses this so we're
stuck with it anyway.
The test is
up->index % 8 >= 3
This is true iff it's a socket policy.

So your kernel is still feeding garbage into lockdep.
Are you really really sure that kernel had Herbert's patch applied?

The above log message is stamped as 13:44 PST. I gotta say
this doesn't look good :)

i may miss something, but wouldn't you prefer to use eth_type_trans
here and just add compare_ether_addr check after it?
