When CONFIG_NETLABEL is disabled, the cipso_v4_validate() function could loop
forever in the main loop if opt[opt_iter +1] == 0, this will causing a kernel
crash in an SMP system, since the CPU executing this function will
stall /not respond to IPIs.
This problem can be reproduced by running the IP Stack Integrity Checker
(http://isic.sourceforge.net) using the following command on a Linux machine
connected to DUT:
"icmpsic -s rand -d <DUT IP address> -r 123456"
wait (1-2 min)

You should also use 'tag_len' inside the for-loop, and after the if-block, where we increment 'opt_iter'. See my original reply for an example.

* [PATCH v2 net-next] net: refactor sk_page_frag_refill()

In-Reply-To: <1381623952.3392.25.camel@edumazet-glaptop.roam.corp.google.com>
From: Eric Dumazet <edumazet@google.com>
While working on virtio_net new allocation strategy to increase
payload/truesize ratio, we found that refactoring sk_page_frag_refill()
was needed.
This patch splits sk_page_frag_refill() into two parts, adding
page_frag_refill() which can be used without a socket.
While we are at it, add a minimum frag size of 32 for
sk_page_frag_refill()
Michael will either use netdev_alloc_frag() from softirq context,
or page_frag_refill() from process context in refill_work() (GFP_KERNEL
allocations)

This looks very wrong.
res.fi could disappear, and we crash.

* [PATCH] bnx2x: record rx queue for LRO packets
From: Eric Dumazet @ 2013-10-12 21:08 UTC (permalink / raw)
To: David Miller; +Cc: netdev, Eilon Greenstein, Willem de Bruijn
From: Eric Dumazet <edumazet@google.com>
RPS support is kind of broken on bnx2x, because only non LRO packets
get proper rx queue information. This triggers reorders, as it seems
bnx2x like to generate a non LRO packet for segment including TCP PUSH
flag : (this might be pure coincidence, but all the reorders I've
seen involve segments with a PUSH)

We must call skb_record_rx_queue() to properly give to RPS (and more
generally for TX queue selection on forward path) the receive queue
information.
Similar fix is needed for skb_mark_napi_id(), but will be handled
in a separate patch to ease stable backports.

How about we go even simpler? helper_fw is *only* used inside
firmware.c anyway, and that's probably where its lifetime should be
handled. Same for the main firmware. I have no idea why the bus code
is responsible for releasing the firmware anyway, when it originates
from firmware.c and control returns back there after the firmware loaded
callback is done. Does the following patch fix your problem too?

AFAIU, ACCESS_ONCE() is not meant to ensure atomicity of load/store, but rather merely ensures that the compiler will not merge nor refetch accesses. I don't think the assert check you propose is appropriate with respect to the ACCESS_ONCE() semantic.

Most of them deal with management, maybe a rtnl_assign_pointer with lockdep
check for rtnl lock could help to not clean up the wrong bits.
I don't know if rtnl_assign_pointer is that a could name as it does not really
explain why the barrier is not needed there. :/

* [PATCH net] tcp: fix incorrect ca_state in tail loss probe
From: Yuchung Cheng @ 2013-10-12 17:16 UTC (permalink / raw)
To: davem, ncardwell, nanditad
Cc: netdev, michael, jwboyer, sesse, dormando, Yuchung Cheng
On receiving an ACK that covers the loss probe sequence, TLP
immediately sets the congestion state to Open, even though some packets
are not recovered and retransmisssion are on the way. The later ACks
may trigger a WARN_ON check in step D of tcp_fastretrans_alert(), e.g.,
https://bugzilla.redhat.com/show_bug.cgi?id=989251
The fix is to follow the similar procedure in recovery by calling
tcp_try_keep_open(). The sender switches to Open state if no packets
are retransmissted. Otherwise it goes to Disorder and let subsequent
ACKs move the state to Recovery or Open.

Sigh. Some afternoons it doesn't pay to touch the keyboard.
Thank you for catching this. I will fix, but at this point, I am thinking
in terms of 3.14 rather than 3.13 for this series.

Oh, I do not think it is useful. It should help enforcing the right memory
orderings if someone uses rcu_assign_pointer in such a nasty way.
It was meant by me as a "defensive rearragement" to guard rcu_assign_pointer
to accidentaly slip memory mutations across the barrier without hurting
compiler optimizations too bad (or at all).

Absolutely! But e.g. the pointer could be preallocated and no length
checks are needed so there is no need for an error path, I guess someone
could think it is safe to put the get_ptr_with_side_effects (and if the
side effect is only a bit flip in the strucutre pointed to by the value)
in the v argument of rcu_assign_pointer.
I also tought about adding a (*(&(v))) statement to enfore that only
lvalues where allowed as the value in rcu_assign_pointer, but that would
already cause compilation errors (e.g. rcu_assign_pointer(ptr, ptr|MARK)).
The nice thing with ACCESS_ONCE(p) is, that there is now no way to put
a non-lvalue expression into the first argument of rcu_assign_pointer. :)
Regarding the volatile access, I hope that the C11 memory model
and enhancements to the compiler will some day provide a better
way to express the semantics of what is tried to express here
(__atomic_store_n/__atomic_load_n with the accompanied memory model,
which could be even weaker to what a volatile access would enfore
now and could guarantee atomic stores/loads).

[-- Attachment #1: Type: text/plain, Size: 398 bytes --]
While upgrading the GTA04 kernel to 3.12-rc4 we came across
an issue with libertas/sdio referencing stale memory on ifconfig up
when trying to load the firmware (for a second time).
I am not at all sure if the patch is how it should be done and the right
location, but it appears to work for us with resetting priv->helper_fw to NULL
before asynchronously loading the firmware again.

Subject: [PATCH] libertas/sdio: fix releasing memory twice. We have connected
a Wi2Wi W2CBW003 to an OMAP3 using SDIO. We have seen an
issue (not related with this patch) that sometimes power is
not turned off. This did lead to a kernel Oops if an
ifconfig up / down / up when the chip was not powered down.
This leads to a second call to lbs_get_firmware_async()
with the same priv data - and that tries to
release_firmware(priv->helper_fw); This appears to be
wrong, since it was alredy released in the
if_sdio_do_prog_firmware.

Guennadi, could you check if this patch fixes your issue with NFS. Make
sure it applies to 'r8a7740_data' (it was misapplied to DaveM's tree).

3.10.16 is just as flaky.
Turning the offloads back off for now, will try to dig a little deeper
later.

* 3.12-git Intel e1000e hardware unit hang / tx queue timeouts
From: Andre Tomt @ 2013-10-12 13:25 UTC (permalink / raw)
To: netdev
[-- Attachment #1: Type: text/plain, Size: 1232 bytes --]
After some interesting commits in 3.12 I figured I'd try to run this
system with the normal packet coalescing offloads enabled. Normally I
disable them to get smoother packet scheduling. But some hours after
turning GSO/GRO/TSO it is getting a bunch of tx timeouts and hardware
unit hangs.
The port hanging is a 82579LM running with hfsc + fq_codel for egress,
and redirecting ingress to a similarly configured ifb device. No
ethernet flow control. This port is internet-facing. em2 in the dumps.
The internal port are only using fq_codel as root qdisc, no hfsc
involved. Also an e1000e, 82574L. This port uses VLAN's, with one rarely
used VLAN device on a bridge for KVM. The majority of traffic moves over
a "clean" VLAN device. No ethernet flow control. em1 in the dumps.
Turning the offloads back off seems to cure it.
Kernel is linus git as of friday 11. oct (yesterday). I'm not sure when
this surfaced as I've not been running with the offloads for a good
while. The ports are on-board, motherboard is an Intel DQ77KB mini-itx.
BIOS identifies as KBQ7710H.86A.0052.2013.0708.1336 (the latest one with
the biosdevname fixes). More info is attached.
I'm going to boot 3.10.16 on it now, and see how it fares.

How does HW compute SCTP checksum when the data is split between skb?
Each skb will be submitted separately to the HW.
I think we need to fall back to SW checksum when packer will be fragmented.

You should also use 'tag_len' inside the for-loop, and after the if-block,
where we increment 'opt_iter'. See my original reply for an example.

You read correctly.
Dropped Rx are more common. Dropped Tx means the driver has not even
been able to hand packets to the network chipset (it sucks).

Your message does not include the XID line that the r8169 kernel
driver (*not* Realtek's own driver) displays to identify the chipset.
It could help.

You may be a (not-so) happy owner of a 8168f. If so you almost surely want
3ced8c955e74d319f3e3997f7169c79d524dfd06 ("r8169: enforce RX_MULTI_EN for
the 8168f.").
It's a post 3.11 kernel patch. You can either use a recent 3.12-rc kernel
or one of the 3.10.16, 3.11.5 stable kernels when they are released.
Your success / failure report will be welcome.
Thanks.

Ok, I got my ball, ten bucks bet this correct ;)
IPv4:
after skb reach fragmentation part, CHECKSUM_PARTIAL denotes
L4 layer protocol need to be checksummed, then IPv4 checksum is
recomputed for each fragmented IPv4 packet.
IPv6:
Here IPv6 doesn't need checksum for its header, again
CHECKSUM_PARTIAL denotes L4 layer protocol need to be checksummed.
So all in all, this is the right place to distinguish SCTP skb out,
and skip checksum operation as hw does it thereafter.
