Hi!

The answer to that pointer was from
http://sourceforge.net/users/guy_harris/
--------
I, at least, have no plan to include anything that requires that, in order
to build tcpdump, a -I flag that points to a header file that's internal to
some project's source tree rather than being installed under /usr/include.
Unfortunately, both packet-pfsync.c and pf_print_state.c, in both that
patch and in OpenBSD, will build only if the include path includes the
source directory for the pfctl command, so I'm not going to do any more
work on this until at least one OS makes all the required include files
public headers installed in /usr/include or a directory under that.
--------
So, if /usr/src/sbin/pfctl/Makefile would install pfctl.h and
pfctl_parser.h into /usr/include/net, the tcpdump people would
include print-pfsync.c.
Any chance for this ?

Since no-one else has mentioned it, see the '-p' option to config(8)
and kgmon(8). There's also dtrace.

Are you saying I can't portably do the following:
# ifconfig ath0 ether 00:11:22:33:44:55
# ifconfig create wlan0 wlandev ath0 ssid my_net up
My understanding was that the first line changes the MAC associated
with ath0. The second line then creates a wlan device and allows ath0
to associate with an AP with ssid "my_net" - and this association will
be performed using the updated MAC address. Which part of this
doesn't work?

Actually, lagg(4) requires all associated interfaces to have the same
MAC address - it doesn't change them during operation. Normally, it
updates the MAC address when it does the "addm" but this doesn't work
for "addm wlan0" (presumably for the reasons you describe) but
manually changing the MAC address of the WiFi NIC before creating the
wlan device avoids this.

Comcast does IPv6 using DHCPv6 and DHCPv6-PD. At least in 8.3-p3, the
in-base dhclient doesn't do DHCPv6. I installed the
net/isc-dhcp42-client port and am successfully using as a workalike
drop-in replacement with the following in /etc/rc.conf:
dhclient_flags="-lf /var/db/dhclient.leases.${ifn} -pf
/var/run/${name}.${ifn}.pid -cf /usr/local/etc/dhclient.conf"
dhclient_program="/usr/local/sbin/dhclient"
According to the port's dhclient man page, I need add "-6" to
dhclient_flags to make dhclient do DHCPv6. The problem is the network
scripts in the base don't differentiate between DHCPv6 and DHCPv4, so
adding that would break my network config (or at least prevent the
system from getting an IPv4 address). Writing my own RC script for this
is completely the wrong solution, so I'm sure I'm overlooking something.
What am I missing?

You can change lagg MAC address to match your wlan MAC address but it changes nothing...

By chance, did vr(4) spew some kind of diagnostics messages to
console? If I remember correctly, vr(4) automatically restarts
controller and show these errors when it detects abnormal
condition. Abnormal conditions for vr(4) would be:
- TX/RX MAC stuck
- RX MAC stop due to FIFO overflow or no RX buffers
- PCI bus errors
- TX abort
- TX underrun

Have you any idea how to find that out for sure?
Add some debug printfs or KASSERT, may be?
I'm ready to test.

None. I've read its source and learned it prints its debug
to the kernel dmesg buffer with sysctl dev.vr.1.stats=1
and done that before, during and after noted failure -
all counters are zero except of good frames conters (in/out).

Sorry, no clue yet. The only wild guess I have at this moment is
handling for VR_ISR_RX_NOBUF/VR_ISR_RX_OFLOW interrupt. It forces
to restart RX MAC by reprogramming VR_RXADDR register. If driver
is out of sync with hardware this may produce unexpected results.
The VIA data sheet I have has no special comments on this as other
VIA data sheets.

Ok, it seems you didn't encounter TX/RX MAC shutdown/restart
related issues. To get more verbose debugging messages, you have
to define VR_SHOW_ERRORS in if_vr.c.
BTW, I see really poor bulk TCP performance on vr(4) with CURRENT
(< 12 Mbps). :-(
This is a quad-port VT6105 with Core2 Duo E6550. Pre-r235334
restores the old good performance for me(> 86Mbps). However I can't
explain how taskq change shows this huge difference.

Hi Glebius,
simple http fetch test give about of 10% of throughput:
before ~59Mbps
after ~65Mbps
I'm not sure that results is precise, but I'm sure it gives few
percent anyway.
Seems no problem in configuration when wired network and wireless
joined into bridge (typical AP).
Thank you very much! Keep going! :)

Have you tried to remove options PREEMPTING from the kernel for newest driver?
That helped me a lot - performance of new driver returned to the level of old one.

Does anyone want to review this patch before I check it in? The change
has been reviewed and tested by coworkers, but not yet reviewed by any
other FreeBSD committers.
http://www.silby.com/patches/if_bxe.c-safestop.patch
This resolves an issue we saw at work where IPMI would report bus errors
when you rebooted a system with bxe NICs if you had not UP'd all of the
bxe NICs before the shutdown.
Thanks,
Mike "Silby" Silbersack

Yeah I also have a similar patch. But I checked sc->state after
getting a BXE_CORE_LOCK as the state is protected by the lock.

Hi Matthew,
Thanks for your reply,
This is my Pciconf and the /var/log/dmesg.boot. As you can see the ethernet
card is there but it is not recognisable in PFSense. The only functional
nics are FXP0 and FXP1 the onboard chipset.

waaaaaaaaait.
Did you say that removing preemption from your kernel fixed your
performance issues?
If that's the case, we need to figure out why both you and i see that..

I'm so sorry for dropping off the radar here.
Can you please compile your kernel with KTR enabled so we can capture
some schedgraph traces?
I'd like to let the scheduler people see what's going on.
I bet it's something like preemption is allowing the taskqueues to
preempt each other (which they shouldn't, not when they're at the same
level) when an interrupt occurs that calls taskqueue_enqueue().
On a non-preempt kernel it'll just jump back to running the same
thread until yield or tick; on a preempt kernel a driver taskqueue
could be preempted by another driver.
(Holy crap, this is one situation where maybe the linux spinlock_bh()
semantics make sense. If used correctly. Yikes.)

Yes, I can and will. What should I do besides of rebuilding
the kernel with KTR and PREEMPTION?

Yes. Also, it seems my original vr(4) troubles (RX path problem)
have gone away since I run the kernel without preemption.

Hello list!
Currently we have the following locking strategy in our firewalls:
On every input/output IP packet PFIL acquires read lock while traversing
list and after that reader (e.g. firewall handler) acquires its own lock
(rwlock in case of ipfw).
Pfil framework currently uses per-head rmlock (e.g. different lock for
IPv4 and IPv6 per each VNET instance).
Since most popular firewalls (ipfw and pf) uses per-VNET rwlock(*),
per-AF pfil locks does not give us much benefit.
Proposed idea is to:
1) Use single pfil lock per VNET instance by default.
2) Permit filters to use this lock via pfil_[rw]_[un]lock functions.
Patch for pfil and ipfw changes attached.
I've got several production routers running for a week with previous
version of this patch without any (ipfw-related) problems.
Performance difference is quite significant, more details here:
http://lists.freebsd.org/pipermail/freebsd-net/2012-July/032842.html
I'm planning to commit these patches (with minor changes) at the
beginning of next week if nobody objects.
(*) currently pf uses mutex, but hopefully glebius@ is working on much
more scalable solution

Hi!
[announce goes both to net@ and pf@, but any discussion should
go on on pf@FreeBSD.org only, please]
As you already may now, last half a year I've been working on
making pf SMP-scalable and faster in general. More info can be
found here:
http://lists.freebsd.org/pipermail/freebsd-pf/2012-June/006643.html
http://lists.freebsd.org/pipermail/freebsd-pf/2012-June/006662.html
Since that announce in June, I've been running experimental code for
more than 2 months in production on several routers. Also, some brave
people volunteered to be beta-testers and also run the experimental
branch in last couple of months. Code proved to be stable enough.
The new code performs better in production: less CPU load, less
jitter, more responsive system under high load. It performs better
under synthetic benchmarks like random generated UDP flood. It
performs much better when DoS comes in.
Thus, I plan to merge projects/pf/head to head this weekend, and
this is a HEADS UP email! You have been warned. :)
What I'd like to do next:
1) Move pf out of contrib.
2) Refactor the pfvar.h into pf.h and pf_var.h. Provide stable
kernel<->pfctl ABI. And probably other clean up tasks.
...
3) ... too far to build any plans, yet. :)

Hi, as continuation of
http://lists.freebsd.org/pipermail/freebsd-stable/2012-April/067307.html
I like to describe what I have done to get smartphones with IPSec VPN's
working with a FreeBSD 8.3 server.
The clients are IPhones with Cisco IPSec (authentication_method
xauth_rsa_server in tunnel mode) and Androids with L2TP over IPSec
(authentication_method rsasig in transport mode). On the server I have
FreeBSD 8.3 with NAT-T support and the ports ipsec-tools-0.8.0_2 and
mpd-5.5.
To filter all packets in transport and tunnel mode on the enc0
interface, I use net.enc.out.ipsec_filter_mask=1 and
net.enc.in.ipsec_filter_mask=3. Further my server has included
the patches given in kern/146190 to ignore checksums and kern/169620 to
avoid packet bypass on ngX.
The following patches are all for netipsec/key.c:
I use parameter "generate_policy on" in racoon.conf. This works for
clients with NAT-T, but direct connected clients need the following
patch (likewise in ipsec-tools/roadwarrior/client/phase1-up.sh):

handling and an important change in calling key_cmpsaidx() from

the same router work correct.

One case is left: At the moment it is not possible for the kernel to
handle more than one IPSEC/L2TP (transport mode) connection from clients
behind the same NAT router. To get rid of this limitation the kernel
must do some housekeeping for the clients inner and outer udp src ports
(the corresponding dst ports are 1701 and 4500) to find the correct
SA for outgoing packets. I do not know what would be the best place to
store these informations. Any suggestions ?
At the end a question: At the beginning of ip_ipsec_output() in
ip_ipsec.c the flag PACKET_TAG_IPSEC_PENDING_TDB is used, but I can not
find the place where this flag is set in the kernel. Can somebody
enlighten me ?

I'm not sure it will happen in real life configurations, but if
someones does really want to setup a SP entry for port 500 (tunnel
mode, or anything else which may need that), your patch will prevent
it from working.
It may be cleaner to have racoon generate the good SP entry, rather
than kernel trying to guess what is right in a SPDADD command.

The SPDADD command is done by racoon because I have generate_policy on,
but racoon sets ports to 500 for direct connected clients. If this would
be fixed in racoon, then the above kernel patch is superfluous.

Its good to see results on your work and is good moving forward.
Claiming better behavior, under DoS or other comparison without showing any data
or technical reason is a bit over this RFC.

Just this reason is a bit contradictory with 1) above!
Let alone what does this mean to the user?! Nothing?
They are after syntax stability, not breaking their machines on
upgrade, ABI is nothing to them.
Please reconsider the option of renaming the import and allowing both
ports to coexist.
Than you can have your changes going through.

Hello Anu,

already some agreement about these proposals, at least there was
in the room, now to get some on net@.

I think these changes might be aided by something that bz@ and I talked
about after the network session, to wit, we could stand to abstract a good
deal of code away from the drivers, and up into the ethernet and other
modules. I think trying to reduce the amount of code in the drivers,
much of which is common code, is the way for us to go. As part
of that we can start to use the functions that you mention.

This would be interesting for many reasons, and I think it would be a good
contribution. Does the work you've done in this area handle the VNET
stuff that is in the stack as well? That is, how well does the network stack
as a module play with the vnet architecture?

So long as you're happy living with them in a .0 that's, I believe,
fine.

One more note. Can you break the patches down into more bite sized =
pieces? They're hard
to review as is.
Best,

Benchmark by authors are always biased, thus I didn't boast about results.
Much better if benchmarking is performed by someone else. If you insist
here is some data:
1) Casting UDP flood of 400k states in this simple setup:
[box A] -> [pf] -> [blackhole]
On my particular box, head pf can forward 520 kpps and anything above is
lost. SMP-pf can do 980 kpps. If we increase number of states, results would
be more dramatic. If we make load bidirectional (which is the case in 99%)
results would be more dramatic. Increasing number of rx/tx threads (more NICs,
or more smart NICs) as well as increasing number of CPUs would make results
even more dramatic.
2) DoSes
Results are just empirical. At my job, when running old pf and encountering
DoS attack, we usually notice that by bad web sites responsibility, customers
complaining, etc. The box under attack is very unresponsive via ssh. With new
SMP-pf a DoS may come in and if it doesn't consume entire bandwidth it can be
noticed only post-factum when looking at monitoring plots.
I'd appreciate if you perform benchmarking and testing. As said above,
results from author are usually biased, but results from opponents more
interesting.

Do you understand that "absense of stable ABI" == "breaking machines
after upgrade"?
Right now, the structures supplied via ioctl() include many fields
that aren't related to API, but are internal kernel. Any internal
kernel change breaks ABI. If new API structures are introduced, then
we can do a lot of hacking on pf in 11.0-CURRENT with ability to
safely merge changes to 10.0-STABLE.

Ok. Can you please compile up both a preempt and non-preempt 4BSD
kernel with KTR enabled?
That way we can capture some schedgraph traces and see what the heck
is going on.

There's some weird, undocumented crap surrounding changing MAC
addresses but in theory, once the right incantation works, that should
work fine.
However, lagg would then have to ensure a broadcast frame will go out
so the forwarding tables get updated. Or else various L2 devices won't
know the location of your device has changed.
I'ms aying if you placed an ath STA vap into a bridge group or some
other device that sent frames from a source MAC that wasn't the STA
MAC, it won't work. That only works with 4-address WDS mode.

I have some KTR traces for SCHED with 4BSD and ULE under load on same
Geode with same vr(4) adapters, but I don't understand how to read
them. Yes, I could look at (very slow, small and bad looking) graphs
with Python/Tk script, but I don't understand, what does it all mean.

Do you see performance issues go away when you disable preemption?

Oh don't worry about polling just yet. I just want to see what
preempt/no-preempt does with ULE and 4BSD on these little single-CPU

Ok, I'll do it. Should I post 4 outputs from ktrdump? Again, I don't
understand how to interpret these data by myself.

Since I saw other panics on our stable/9 I started poking around and found this one lying around too.
And, I have a crashdump here as well. Not sure about reproduction, but I see it happened on two seperate servers
over the course of the day. Here is one of them.

Hi George,
Thanks for taking a look. Some answers/comments below.

I'll follow up on this one separately.

We use the first one as a 'direction' to the forwarding path to select an
appropriate priority queue to send the packet on. In a generic (i.e.
Something other than our specific system) system, one could consider
interesting ways to use queues on a multi queue NIC with help from a
driver. The second one is for a system with logical routing capabilities
(multiple routing systems within the same chassis). It gives an
application opening a socket an option to select the specific logical
routing instance.
I'll provide smaller pieces of diffs for the kernel without networking
patch I'd sent out. Let me know if you prefer the device driver interface
to be in that too.
Thanks,
Anu

We've had similar problems with lagg at work, each lagg is made up of
one igb and one em port, sometimes for no apparent reason they seem to
stop passing through traffic. The easiest way we've found to get it
working again is ifconfig down and up on one of the physical
interfaces. This is on 8.1

I assume
http://forum.pfsense.org/index.php?PHPSESSID=d9f0e7e874a14184be2074988f0f4a8a&topic=53277
is you also.
>From the look of it and reading that thread I would say that the quad
Gig card is not being exposed as standard intel adapters to the OS, but
in a modified way though the rapidstream daughterboard. Note that the 2
fxp cards have
chip=0x12098086 (device ID 0x1238 Vendor ID 0x8086)
Indicating they are Intel chips, while the other card appears as
chip=0x02011617 (Devince 0x0201 Vendor 0x1617)
Indicating its a Rapidstream device.
As far as I know this is not supported by FreeBSD but would be happy to
be proved wrong if someone else knows differently.

I guess I know this one. The problem is a race in in_pcblookup_*() when
two threads want to acquire a pcb read-locked and third thread detaches
it. I have reported this to Robert and now waiting for reply.

We have the second one with the SETFIB socket option, which allows
a socket to select the routing instance (fib) to use.
it's in the diff, 3 lines up.

OK, that's what I guessed but thanks for confirming it.

John:
Hey, I'm currently testing a patchset that enables the use of the 1Gig
adapter via bge(4). I'm not sure about the 10Gig adapter though, is
that bxe(4)
At this time, there no functional version of bge(4) that works on a
stable release. You'd have the best luck in compiling your own kernel
from stable/9 and applying the following updates from

You'll need to overwrie brgphy.c in sys/dev/mii and move if_bge.c
if_bgereg.h to sys/dev/bge and recompile your kernel.

I did an analysis of this pr a while back and I figured I'd share. =
Definitely looks like a real problem here, but at least in 8.2 it is =
difficult to hit it. First off, vlan tagging is not required to hit =
this. The code is question does not account for any amount of =
link-local header, so you can reproduce the bug even without vlans.
In order to trigger it, the tcp stack must choose to send a tso "packet" =
with a total size (including tcp+ip header and options, but not =
link-local header) between 65522 and 65535 bytes (because adding 14 byte =
link-local header will then exceed 64K limit). In 8.1, the tcp stack =
only chooses to send tso bursts that will result in full mtu-size =
on-wire packets. To achieve this, it will truncate the tso packet size =
to be a multiple of mss, not including header and tcp options. The =
check has been relaxed a little in head, but the same basic check is =
still there. None of the "normal" mtus have multiples falling in this =
range. To reproduce it I used an mtu of 1445. When timestamps are in =
use, every packet has a 40 bytes tcp/ip header + 10 bytes for the =
timestamp option + 2 bytes pad. You can get a packet length 65523 as =
follows:
65523 - (40 + 10 + 2) =3D 65471 (size of tso packet data)
65471 / 47 =3D 1393 (size of data per on-wire packet)
1393 + (40 + 10 + 2) =3D 1445 (mtu is data + header + options + pad)
Once you set your mtu to 1445, you need a program that can get the stack =
to send a maximum sized packet. With the congestion window that can be =
more difficult than it seems. I used some python that sends enough data =
to open the window, sleeps long enough to drain all outstanding data, =
but not long enough for the congestion window to go stale and close =
again, then sends a bunch more data. It also helps to turn off delayed =
acks on the receiver. Sometimes you will not drain the entire send =
buffer because an ack for the final chunk is still delayed when you =
start the second transmit. When the problem described in the pr hits, =
the EINVAL from bus_dmamap_load_mbuf_sg bubbles right up to userspace.
At first I thought this was a driver bug rather than stack bug. The =
code in question does what it is commented to do (limit the tso packet =
so that ip->ip_len does not overflow). However, it also seems =
reasonable that the driver limit its dma tag at 64K (do we really want =
it allocating another whole page just for the 14 byte link-local =
header). Perhaps the tcp stack should ensure that the tso packet + =
max_linkhdr is < 64K. Comments?
As an aside, the patch attached to the pr is also slightly wrong. =
Taking the max_linkhdr into account when rounding the packet to be a =
multiple of mss does not make sense, it should only take it into account =
when calculating the max tso length.
