last night we tested Wireguard with LEDE on a fairly weak mashine - TP
Link 841N v11.1 with 4MB flash, 32MB ram, and 650 MHz cpu.
we choose this router model because we have some hundred of them
deployed in our free wifi for the public networks around our city. (as
mentioned before Freifunk Freiburg https://freiburg.freifunk.net ) We
were interestet in Performance and what we (maybe) can do with wireguard
we described it in detail here
https://forum.freifunk.net/t/lede-test-wireguard-und-blanko-durchsatz-tp841nv11-1-und-bug/13163
brief summary - sharing of experiences
netifd crashed via iperf3 test from laptop - 841Nv11 - 841Nv11 - laptop
iperf was running on laptops, wireguard as tunnel between 841Nv11
Routers, all connected via cable.
without wireguard, so plain routing we got 93 MBs (for refference)
and with Wireguard so far 15.5 MBs
there are clearly some heavy problems with netifd from LEDE/Openwrt ...
we simply ran in heavy load (2.6++) and out of memory
here some notes and dmesg output:

Hi Jens,
Youch! That's pretty horrible. Is 15mb/s worse than what you get with tincd?
A while ago Baptiste (attached) was working on a MIPS optimized
implementation of ChaPoly. Baptiste -- what ever happened with that?
Perhaps it's time we revive that project?
About the crash -- it appears that I need to optimize WireGuard for
low memory situations. I'll get started on this.
Thanks for the feedback. I'll see what I can do to fix things.
Jason

the mentioned tincd...
We ran other tests on our backbone vms. There we build plain l2tpv3/batv15 on top and we got heavy promising results.
In short: plain we got there 980mbs, with wireguard some 700 and l2tpV3/batv15 on top 500mbs.
we will report that soon as working alternative to tincd, while tincd only interconnet our backbone.
the small routers run fastd into the backbone.
That was Indeed this test about, if this could be an alternative or extension for the small nicely working userspace fastd - and curiosity.
On that mentioned backbone tests we have a huge drop in performance when packets where fragmented, everything goes down to stable 50mbs, and raise to stable 500 if unfragmented. we have to solve this mystery before we will come forward, or if we cannot solve this, we may report as is.

Is the performance of wireguard better or worse than fastd?
Theoretically wireguard should be much faster, so if it isn't already
so in practice, I'd like to optimize a bit.

It should however not lead to netifd outofmemory, load of 2.6 and the oomkiller berserking around at all... even if its not directly wg fault.
Yesterday there was no time to test fastd in such a setting,
Similar test show 5 to 15mbs depending on used crypto in the past.
But there we test laptop - 841v9(550mhz?) - broadbanduplink - backboneserver
If we are motivated, we check fastd in the next days against different cypher algos in exact the same setting, to have a realy good base for comparing software on this fairly week devices

One thing to try would be removing these lines from src/socket.c:
socket.c
386: sk_clear_memalloc(sock);
394: sk_set_memalloc(sock->sk);
I'd be interested to learn if that fixes things.

Hey Jason!
It was too late for me yesterday night so i wasn't able to write something on
this.
I know we have to reproduce this once again - i was not prepared to face
something like this so we had no tools installed to check memsuage.
Let us run this test well-prepared again and we may come up with more
details..
best regrads,

Hey,
Do you guys have a good way of running your setup inside Qemu? I'd
like to debug this issue a bit...

Hey Jason!
I didn't run openwrt ar71xx targets in qemu yet.. ATM i am recompiling
my qemu to be able to run mips on it, but i don't know if this will work
anyway..
I will have a look at it and come back if i have something to work with.
best regards,
n3ph

Hi Jason!
I figured out how to run openwrt on qemu.. It seems it is just possible
to run the malta target on mipsel - discribed here:
http://aleph0.info/software/lisp-forth-openwrt/openwrt-on-qemu.html
I tried ar71xx but had no luck to get things work..
So i just got the images from
https://downloads.lede-project.org/snapshots/targets/malta/le/
and execute qemu by
qemu-system-mipsel -kernel lede-malta-le-vmlinux-initramfs.elf
-nographic -m 256 -append "console=ttyS0"
Hope thats helps..
best regards,
n3ph

sorry if you waited for answers ..
we redo the testing with latest kernel
[ 0.000000] Linux version 4.4.15 (fuzzle@builder) (gcc version 5.4.0
(LEDE GCC 5.4.0 r1119) ) #3 Thu Jul 28 01:05:08 UTC 2016
build from latest trunk by ourselve, before we use default packages and
lede like this
[ 0.000000] Linux version 4.4.15 (buildbot@builds) (gcc version 5.4.0
(LEDE GCC 5.4.0 r1114) ) #2 Tue Jul 26 17:57:45 UTC 2016
and with wireguard source from 27.7. also including your suggestions.
still the same
more detailed :
we got out of memory and big cpuload when testing iperf with udp
packets, (we forget to notice that before in our first testings which
mode killed all the memory)
and from the heavy load and low memory lede/openwrt shut down stuff and
things broke apart
(Reminder, Lede/Openwrt on TP link 841 v11 with 650 Mhz CPU and 32Mb Ram)=
with tcp traffic we got this time stable 16 Mbit, which sounds like a
reasonable limit for this kind of small cpu without any optimzation.
Also cpu load was lower.
we wonder how to use more sophisticated tools on our testsetup with 2
real tplink routers connected + behind each one laptop to measure
throughput with iperf3. this maybe is not possible at all without
getting serial console access
2 lessons learned: 1. problem arises with upd traffic and result quickly
in out of memory (with transmission peak at the beginning higher than
the 15 mbit with tcp packets)) 2. tcp is stable with 15-16 Mbit
some more thoughts: all this could maybe slightly increased by code
optimization, slightly different cipher, maybe encrypting is harder than
decrypting, which means download will be faster - while encryption is
happen on big servers in Net
to compare again with fastd - this are the numbers we could get fastd
through the cpu/wire (we didnt did that testing in this special setup,
maybe some time soon - at least i am curious)

Hi Jens,
Thanks for the feedback.

Okay, so I interpret this as you saying "I removed the sk_set_memalloc
line, but that didn't fix the problem."
Next test: remove the line "sock->sk->sk_sndbuf = INT_MAX;" Does that
then fix the problem?
I'll continue to investigate this too.
Jason

To: wireguard
Hi Jens,
I would like to share my results on a MIPS cpu.
I also tested wireguard on a router. TP-Link WR1043ND v1.08 with a
Atheros AR9132 400MHz cpu.
Running LEDE 28-july-2016, wireguard & iperf3 via packagemanager.
For my test I run wireguard and iperf3 on the same device on both sides.
Other side is a AMD A6-5400 with debian unstable running inside KVM.
Both connected to a gigabit switch.
My results iperf:
- Plain ~100MBits
- WG ~24Mbits (TCP test)
Greats,
René van Dorst.

so you do not observe crashing of the router like we do with the tp-link
wr841Nv11 -
do you also test iperf with udp packets , around 200 Mbit or so ?
acording to openwrt wiki say that 1043v1.xx runs even slower cpu , but
have 8Mb of flash
TL-WR1043ND v1-v1.11 Atheros AR9132 400 8 32 Atheros AR9100
(integrated) b/g/n 5 1x 2.0 Yes
as far as i understand is the lan also on the wifi chip, so this differs
..
for the 841v11 it should be QCA9533-AL3A running with 560 MHz with 32 MB
Ram Zentel A3S56D40GTP-50L. switch QCA9533-BL3A built-in
https://wiki.openwrt.org/toh/TP-Link/tl-wr841nd
https://wiki.openwrt.org/toh/TP-Link/tl-wr1043nd
sidenode tplink name convention (to prevent confusion): mainly important
is running number like 1043 or 841 and the hardware revision like v11,
the N or ND are only antenna related, the .123 are factory firmware
revision of the specific hardware revision - which is more important for
us here

Hi Jens,
I see I made a typo about hardware version. It is v1.8 not v1.08.
LEDE version is Reboot (HEAD, r1178) of 29-july-2016.
I ran a 2 hour test for you and it did not crash. May be not long enough?
Results after around 2 hour testing udp iperf3 over wireguard

This router is a spare router and only used for the vacations to share
wifi connection.
I would like to use Wireguard to secure my trafic.
Greats,

Hello Jens,
Your prior communications have not been clear to me, and recently somebody
took the mailing list off the CC. In order to steer this conversation back
on a useful track, please check all that apply:
[ ] I have tried removing "sk_clear_memalloc(sock);" and
"sk_set_memalloc(sock->sk);"
from socket.c, and the problem still continued.
[ ] I have tried removing "sock->sk->sk_sndbuf = INT_MAX;" from socket.c,
and the problem still continued.
[ ] I do not know how or am unable to make changes to the source code,
recompile, and test these changes.
[ ] I have an extra device that I can mail to Jason so that he can debug
the issue.
Thanks,
Jason

* for the extra device we may pay new ones , since you easily get them
for 15 euro per part (the TP link 841N)
* buildchain for crosscompiling is ready now, but unfortunately we test
it in our local hack space when there is free time, (n3ph and me) could
be in the next days ..
by the way : the setup from Rene is different: see this same thread -
message from 11h today from Rene.
(mainly he run iperf on one routerdevice direct, and only connect to wg
outside, where we build a uniqe wireguard bridge between two similar
routerdevices and no iperf had to be done (and regulated) on this
devices ... just storms of packets)

we just want to inform you that we want to run some more tests in the
next days, including your suggestions and compare all with fastd (which
we also test), and everything also on a different router - we write to
the list as soon we have some results on this.
Testsetup will stay the same: (see first post for details)
laptop (iperf3) > tp841v11 <- WireGuard -> tp841v11 < laptop (iperf3)
we will test
fastd,
default lede Wireguard(20160630),
latest wireguard(20160808),
latest wireguard without memalloc(step1) ,
latest wireguard without sndbuf = INT_MAX (step2)
we will also compare the setup to a similar router : TPLink cpe210 ,
with 64MB ram and 8 mb flash with similar cpu (maybe not with all tests
so far)
the ready to use builded packages (Firmware and ipk) are already laying
here http://openfreiburg.de/freifunk/firmware/
if some want to play around with them.
if there are any suggestions and ideas we could/should add, we are happy
to hear from you
(its all about hunting the out of memory issue on heavy udp traffic
through wireguard tunnel)

by building i ran in the same error described here ..
[LEDE-DEV] kmod-udptunnel{4, 6} packages are empty (Was: Kernel symbol
dependencies and KCONFIG usage for kernel packages)
<https://www.mail-archive.com/search?l=lede-dev@lists.infradead.org&q=subject:%22Re%5C%3A+%5C%5BLEDE%5C-DEV%5C%5D+kmod%5C-udptunnel%5C%7B4%2C+6%5C%7D+packages+are+empty+%5C%28Was%5C%3A+Kernel+symbol+dependencies+and+KCONFIG+usage+for+kernel+packages%5C%29%22&o=newest>
udptunnel4 and 6 are build malicously , so i cant do any of the tests
actually ..
i try this patch
https://git.lede-project.org/?p=lede/hauke/staging.git;a=commitdiff;h=195413a223fb1d6f91927a2c5a8780c7b1829f76
as suggested in

sorry for that .. but all buildings from my side before to test you
suggestions were faulty , so i have to solve this before - which again
takes some time
