Am I correct in assuming that the documentation is supposed to word-wrap
somewhere around 72 columns? If so, as I have time for floor sweeping I
can try to go through more of it.

You weren't the only one - what triggered my looking at that description
in the first place was an assertion in the tcpm mailing list that Linux
defaulted to ecn enabled.

If you have some of the particulars, feel free to send them to me
offline. Being one of the cobbler's children I cannot make promises but
I can try to see if whatever it was has evolved since then.

Perhaps one or more of the "development oriented" (term?) distros can
ship with a sysctl.conf file that sets it to one? Or some companies
with rather large Internet presence.
At the time of the tcpm message I went ahead and set it to one on
netperf.org but that is far from a large scale experiment. It has been
a couple weeks and I've captured almost 250000 SYN segments (netperf.org
isn't all that busy). My recollection is that at least one search
engine provider's bots were negotiating ECN and one noteable one was
not. I'd think a search engine provider's crawlers would be a large
scale experiment.

* [PATCH net-next v1 3/3] net/mlx4_en: Set number of rx/tx channels using ethtool
From: Amir Vadai @ 2012-11-29 19:21 UTC (permalink / raw)
To: David S. Miller; +Cc: Amir Vadai, Or Gerlitz, Oren Duer, netdev
In-Reply-To: <1354216903-830-1-git-send-email-amirv@mellanox.com>
Add support to changing number of rx/tx channels using
ethtool ('ethtool -[lL]'). Where the number of tx channels specified in ethtool
is the number of rings per user priority - not total number of tx rings.

We need to re-set tx moderation information after calling set_ringparam
else default tx moderation will be used.
Also avoid related code duplication, by putting it in a utility function.

The man page of rds says this:
The default values for the send and receive buffer size are
controlled
by the A given RDS socket has limited transmit buffer
space. It
defaults to the system wide socket send buffer size set
in the
wmem_default and rmem_default sysctls, respectively. They can
be tuned
by the application through the SO_SNDBUF and SO_RCVBUF socket
options.
rds_sendmsg (net/rds/send.c) checks this limit a bit later (after
rds_message_alloc()):
while (!rds_send_queue_rm(rs, conn, rm, rs->rs_bound_port,
dport, &queued)) {
rds_stats_inc(s_send_queue_full);
/* XXX make sure this is reasonable */
if (payload_len > rds_sk_sndbuf(rs)) {
ret = -EMSGSIZE;
goto out;
}

I think it would be wrong if ping worked as you suggest. Binding to an
interface means use that interface as the source of your packets, and having
it bind hard helps when using systems with multiple NICs on same subnet
(or possibly, same IP).

In my opinion, -I <iface> should use SO_BINDTODEVICE, but at least in
older versions of ping it did not.

Do keep in mind this is only 16 Kbytes (256 * 64 bytes = 16384 bytes).

I must agree, that it is perhaps better usage of the memory to just
increase the hashsz (and drop ____cacheline_aligned_in_smp), especially
with the measured performance gain.
> You gave no performance results for this patch anyway.
Yes, I did! -- See cover-mail patch 08 vs 09.
But the gain is really too small, to argue for this cache alignment.
Patch-08:
2x10G size(4416) result:(5024+4925)= 9949 Mbit/s
V2 result:(5140+5206)=10346 Mbit/s
4x10G size(4416) result:(4156+4714+4300+3985)=17155 Mbit/s
V2 result:(4341+4607+3963+4450)=17361 Mbit/s
(gen:6614+5330+7745+5366 =25055 Mbit/s)
Patch-09:
2x10G size(4416) result:(5421+5268)=10689 Mbit/s
V2 result:(5377+5336)=10713 Mbit/s
4x10G size(4416) result:(4890+4364+4139+4530)=17923 Mbit/s
V2 result:(3860+4533+4936+4519)=17848 Mbit/s
(gen:5170+6873+5215+7632 =24890 Mbit/s)
Improvements Patch 08 -> 09:
2x10G size(4416):
RunV1 (10689-9949) =740 Mbit/s
RunV2 (10713-10346)=367 Mbit/s
4x10G size(4416):
RunV1 (17923-17155)=768 Mbit/s
RunV2 (17848-17361)=487 Mbit/s
Its consistently better performance, but given magnitude the other
improvements, I don't want to argue over "wasting" 16Kbytes kernel
memory.
I have some debug patches for dumping the content of the hash, which
shows that at 4x10G size(4416) three frags, 206 frag queues, cross CPU
collisions occur anyhow.
Lets focus on the other patches instead.

* [PATCH v3 net-next 0/2] myri10ge: LRO to GRO conversion
From: Andrew Gallatin @ 2012-11-29 21:07 UTC (permalink / raw)
To: David Miller; +Cc: netdev
Hi,
The following patchset is a resubmission of '[PATCH resend net-next 0/3]
myri10ge: LRO to GRO conversion', and converts myri10ge from using
the old inet_lro interface to GRO, and to do vlan tag decap in
the driver so as to not suffer a performance penalty for vlan
tagged traffic due to the conversion.
Changes this time are:
- Clean up some messy indenting & parens in
"2/3 myri10ge-Add-vlan-rx-for-better-GRO-perf"
and store the vlan hdr csum in a variable, so now we are not calling
csum_partial() nested so deeply it spreads across 3 lines
- Folded 3/3 myri10ge-Use-skb_fill_page_desc into 1/3
myri10ge-Convert-from-LRO-to-GRO.patch since it is really just small
part of the LRO removal cleanup. It was originally a separate patch
because I noticed the cleanup at the last second, and was too lazy
to fold it into the first patch where it belonged.
Note that a naive LRO->GRO conversion of myri10ge will result in a
performance regression for vlan tagged frames. This is because
myri10ge does not offer hardware vlan tag offload, and because GRO
requires hardware vlan tag offload to aggregate vlan tagged frames.
To address this performance regression, I have implemented vlan tag
popping in the myri10ge driver, as it seems to be the lesser of two
evils. As eric.dumazet@gmail.com commented when I asked about this on
netdev: "Given GRO assumes NIC does hardware vlan
offloading, I guess I would chose to do that. It seems unfortunate to
add vlan decap in GRO path, already very complex."

Convert myri10ge from LRO to GRO, and simplify the driver by removing
various LRO-related code which is no longer needed including
ndo_fix_features op, custom skb building from frags, and LRO
header parsing.

* [PATCH v3 net-next 2/2] myri10ge: Add vlan rx for better GRO perf.
From: Andrew Gallatin @ 2012-11-29 21:07 UTC (permalink / raw)
To: David Miller; +Cc: netdev
Unlike LRO, GRO requires that vlan tags be removed before
aggregation can occur. Since the myri10ge NIC does not support
hardware vlan tag offload, we must remove the tag in the driver
to achieve performance comparable to LRO for vlan tagged frames.
Thanks to Eric Duzamet for his help simplifying the original patch.

* [RFC PATCH 0/2] Fix some multiqueue TUN problems
From: Paul Moore @ 2012-11-29 22:06 UTC (permalink / raw)
To: netdev, linux-security-module, selinux; +Cc: jasowang
A relatively short patchset to fix some problems that have arisen from
the multiqueue TUN work. I'm sending this a RFC for now as it changes
the LSM TUN interfaces and therefore crosses a few boundaries,
e.g. SELinux, although it does so only in an effort to restore the
original behavior which was lost in the multiqueue conversion.
I'm not particularly enthused with the idea of passing a void** as a
parameter to security_tun_dev_alloc_security() but the alternatives
would be to move the tun_struct out of tun.c or have the LSM interface
return a pointer (which would require us to return a "fake" non-NULL
pointer when the LSM was disabled) ... neither of these seemed like good
alternatives to me.
I've compiled the code and booted it without drama, but I haven't really
stressed it too much so buyer beware at this point. Comments are always
welcome ...

On error, the error code from tun_flow_init() is lost inside
tun_set_iff(), this patch fixes this by assigning the tun_flow_init()
error code to the "err" variable which is returned by
the tun_flow_init() function on error.

In-Reply-To: <20121129215724.30020.69464.stgit@sifl>
This patch corrects some problems with LSM/SELinux that were introduced
with the multiqueue patchset. The problem stems from the fact that the
multiqueue work changed the relationship between the tun device and its
associated socket; before the socket persisted for the life of the
device, however after the multiqueue changes the socket only persisted
for the life of the userspace connection (fd open). For non-persistent
devices this is not an issue, but for persistent devices this can cause
the tun device to lose its SELinux label.
We correct this problem by adding an opaque LSM security blob to the
tun device struct which allows us to have the LSM security state, e.g.
SELinux labeling information, persist for the lifetime of the tun
device.

In the reboot case... Because it *was* open and the device has no way of
knowing that the host just rebooted. We don't reset the card on loading
the driver, because that would cause an ADSL resync.
Perhaps we could send a 'close all VCCs' command to the firmware though.
Nathan, could we add that to the firmware?
Or we could just respond to any unwanted incoming packet by sending a
close for that specific VCC. And be careful about potential races with
open().
In the close case... The *tasklet* is running to process an incoming
packet, finds an open and active VCC and is *about* to send a packet up
to it. Meanwhile, our close() runs and the VCC is destroyed. And then
the tasklet... oops, use-after-free and crash.
Hence commit 1f6ea6e51 which makes the tasklet refuse to process RX for
a VCC which doesn't have the ATM_VF_READY flag set. Because it knows
it's *being* closed. And the close() routine waits for any *existing*
tasklet run to finish, to make sure nobody's referencing the VCC, before
it returns and allows vcc_destroy_socket() to complete. It's the RCU
principle, basically.

This is basically what Krzysztof's patch 1/7 was doing, which we've now
dropped from the series.
There are issues with *either* ordering.
The current case is that we call vcc->dev->ops->close(vcc) *first*,
before vcc->push(vcc, NULL). And that means that the device is told to
close the VCC while the protocol may still be pushing packets to it.
Hence the patches to both pppoatm and br2684 to make them check for
ATM_VF_READY and *stop* pushing packets if it's not set.
If we flip it round and tell the protocol first, then it tears down all
its data structures while the driver is still happily calling its
->pop() on transmitted skbs. Which leads to the panic in br2684_pop()
that we've *also* seen (because we weren't actually flushing the TX
packets in the driver's close(), which had the same effect). Yes, you
suggest that the protocol could keep track of the skbs it's sent down
and wait for them... but surely it's better to let the driver get called
first and *abort* them?
At this point, I think we're better off as we are (with Krzysztof's
patch 1/7 dropped, and leaving vcc->dev->ops->close() being called
before vcc->push(NULL). We've fairly much solved the issues with that
arrangement, by checking ATM_VF_READY in the protocols' ->push()
functions.

I disagree, once we have spend energy on allocation a frag queue and
adding just a single packet, while the entry is warn we must not drop
it.
I believe, we need the concept of "warn" entries. Without it you scheme
is dangerous, as we would retain entries with missed/dropped fragments
too long.
> Otherwise, as I said, the decision seems arbitrary.
This patch/system actually includes a "promise/probability of
fulfillment". Let me explain.
We allow "warn" entries to complete, by allowing (new) fragments/packets
for these entries (present in the frag queue). While we don't allow the
system to create new entries. This creates the selection we interested
in (as we must drop some packets given the arrival rate bigger than the
processing rate).
(This might be hard to follow)
While blocking new frag queue entries, we are dropping packets. When
fragments complete, the "window" opens up again. Creating a frag queue
entry, in this situation, might be for a fragment which already have
lost some packets, thus wasting resources. BUT its not such a big
problem, because our evictor system will quickly kill this fragment
queue, due to the LRU list (and the fq getting "cold").
I have through of keeping track of fragment id's of dropped fragments,
but is a scalability problem of its own to maintain this list. And I'm
not sure how effective its going to be (as we already get some of the
effect "automatically", as descrived above).

It is VERY important that you understand/realize that throwing more
memory at the problem is NOT the solution. It a classical queue theory
situation where the arrival rate is bigger than the processing
capabilities. Thus, we must drop packets, or else the NIC will do it for
us... for fragments we need do this "dropping" more intelligent.
For example lets give a threshold of 2000 MBytes:
[root@dragon ~]# sysctl -w net/ipv4/ipfrag_high_thresh=$(((1024**2*2000)))
net.ipv4.ipfrag_high_thresh = 2097152000
[root@dragon ~]# sysctl -w net/ipv4/ipfrag_low_thresh=$(((1024**2*2000)-655350))
net.ipv4.ipfrag_low_thresh = 2096496650
4x10 Netperf adjusted output:
Socket Message Elapsed Messages

Can we agree that the current evictor strategy is broken?

(Plus, the size of the frag queue struct, which is also being accounted

Yes, I would say the interval between ipfrag_high_thresh and
ipfrag_low_thresh seems quite a stupid default.

Not really, you drop packets because of another limit.

Thats the typical head/tail drop choice. There is no bad/good choice.
Implementing head drop or tail drop is not a matter of only dealing with
regular traffic. We also can face DOS attacks, with packets of different
sizes and have to choose a compromise.
For example, it seems we have no protection against an attack using
small frags (but big truesize). So a particular 'packet' could consume
all the truesize we allowed for the whole frags queue.
skb_try_coalesce() cant always deal with this kind of thing.
Basically, thats why using frags in the first place is a bad choice.
