#openwrt-devel on 2021-03-22 — irc logs at freenode.irclog.whitequark.org

00:53 <mangix> pkgadd: yeah. they happen to be a pain to peel

01:01 <mangix> damn, now i need a pinout for serial

01:29 <mangix> meh. can't figure out a pinout

01:30 <mangix> 5 pins, 3 of them at 3.3V

01:35 <pkgadd> https://openwrt.org/toh/linksys/linksys_e8450#serial doesn't help?

01:40 <mangix> it does not

01:41 <mangix> that has 6 pins. this router has 5

02:53 <owrt-snap-builds> Build [#11](https://buildbot.openwrt.org/master/images/#builders/31/builds/11) of `layerscape/armv8_64b` completed successfully.

03:50 <mangix> Code_pattern not match: magic='V▒▒(&`VZ`, should be GOLF!

03:50 <mangix> huh

04:00 <mangix> very strange. i get output on serial but I can't seem to do any input

04:06 <mangix> oh nice. got it working

04:06 <mangix> now to generate a proper image...

04:19 <philipp64> mangix ynezz aparcar[m]: I build on Ubuntu 20 and it's been mostly painless...

04:24 <mangix> philipp64: i mean image that the router would accept

04:25 <mangix> trying and failing to add support for a linksys device

04:25 <mangix> i'll need to bust out hexdump tomorrow.

04:25 <philipp64> was chipping in on the "Debian 10" bashing above... there is an alternative...

04:43 <dorf> ubuntu is debian without the licensing fascism.

04:43 <dorf> oh, and the bi-annual update cadence doesn't hurt, either.

04:47 <mangix> what licensing fascism?

04:50 <dorf> Firefox vs Iceweasel, case in point.

04:50 <mangix> ah. I don't use either debian nor ubuntu on the desktop

04:51 <dorf> Back when flash was a thing, iirc Debian didn't offer that, either.

04:51 <aparcar[m]> mangix: you got a 8450?

04:51 <mangix> aparcar[m]: e7350

04:52 <aparcar[m]> ¯\_(ツ)_/¯

04:52 <aparcar[m]> Okay cool

04:52 <mangix> it's a ramips ax router

04:57 <KGB-0> https://tests.reproducible-builds.org/openwrt/openwrt_mediatek.html has been updated. (62.5% images and 98.2% packages reproducible in our current test framework.)

08:26 <ynezz> mangix: eh, why mt7621? why not mt7622?

08:27 <mangix> ynezz: what do you mean?

08:28 <rsalvaterra> 'morning!

08:29 <mangix> rsalvaterra: it's 1:30 AM here

08:29 <rsalvaterra> mangix: Joined the MT7621 club, I see. :)

08:29 <ynezz> mangix: why do you bother with 7350 if there is much better 8450? :)

08:29 <rsalvaterra> mangix: 8:29 AM here. :)

08:30 <ynezz> mangix: AFAIK 7350 is mt7621, right?

08:30 <mangix> ynezz: cheaper. I don't get the mt7622 equipment. It seems like it's all b/g/n on 2.4 ghz

08:30 <ynezz> how much did you paid?

08:31 <mangix> $89 .

08:31 <ynezz> I've got mine Belkin RT3200 for 90EUR from amazon

08:31 <ynezz> which is essentially rebranded Linksys 8450

08:31 <mangix> That Belkin was available for $96 here.

08:32 <mangix> Used of course. I don't buy new routers anymore.

08:32 <ynezz> I've bought used one as well

08:32 <ynezz> it's for testbed anyway

08:33 <rsalvaterra> I like the MT7621 because it's SMT MIPS. Not really a usual feature in the MIPS world. :)

08:34 <mangix> pff. Overrated.

08:34 <rsalvaterra> mangix: I didn't get it for the performance. If I need performace, I have the Omnia. :P

08:34 <mangix> mips74kc is faster per clock

08:34 <rsalvaterra> mangix: The 1004Kc has a higher clock. And dual cores.

08:35 <rsalvaterra> And the 1074Kc is vapourware.

08:35 <mangix> Doesn't make up for it. I remember WireGuard benchmarks showing the C7v2 having faster performance.

08:36 <mangix> Plus the C7 can be overclocked to 1Ghz

08:36 <mangix> Stable too.

08:37 <rsalvaterra> mangix: The C7 v2 faster? At factory clock rates? I'd have to see it to believe it.

08:38 <rsalvaterra> I have a C6 v2 (775 MHz 74Kc) and the 1004Kc is faster.

08:39 <mangix> at WireGuard? That I find hard to believe :)

08:40 <rsalvaterra> mangix: At SQM, at least. I can't see why WireGuard would be any different.

08:40 <rsalvaterra> I think there's a page on the wiki with some VPN benchmarks…

08:41 <rsalvaterra> mangix: Found it… https://openwrt.org/docs/guide-user/services/vpn/wireguard/performance

08:41 <mangix> https://forum.openwrt.org/t/comparative-throughput-testing-including-nat-sqm-wireguard-and-openvpn/44724 is what I have bookmarked

08:42 <rsalvaterra> The Archer C6 v2 is a QCA9563.

08:43 <rsalvaterra> mangix: There's no MT7261 in that forum post. ;)

08:43 <mangix> Yeah I seem to remember wrong.

08:54 <mangix> Hmm running out of space on my NAS. Wonder if I should get rid of clang.

09:00 <mangix> 300MB freed

09:00 <mangix> wow

09:01 <rsalvaterra> Uhh… Is clang that fat?

09:01 <mangix> It's LLVM mostly

09:02 <rsalvaterra> mangix: Hmm… I have LLVM on all computers… because mesa.

09:04 <ynezz> some Belkin RT3200 porn https://gist.github.com/ynezz/0cac6334e456a491e93db00441182621

09:04 <rsalvaterra> ynezz: Oooh, the antennas aren't soldered, nice!

09:05 <ynezz> but not clued either, so got one u.fl disconnected on arrival...

09:05 <ynezz> s/clued/glued/

09:06 <rsalvaterra> Ouch, that must have been a rough bump.

09:06 <ynezz> I've bought it used, so who knows :P

09:06 <mangix> I don't think I've ever shown my Archer C7v3

09:07 <mangix> That thing is insane.

09:08 <mangix> Same SoC as v2 but comes with heatsinks stock. Also a bigger wifi card.

09:08 <rsalvaterra> mangix: Pictures, please! :)

09:09 <mangix> I wonder what qualcomm's rationale for making it was

09:09 <mangix> . Well Qualcomm Crack Addicts I guess.

09:10 <rsalvaterra> Thanks to those drugs you can replace its nasty QCA9880 card… :P

09:12 <owrt-snap-builds> Build [#13](https://buildbot.openwrt.org/master/images/#builders/69/builds/13) of `zynq/generic` failed.

09:12 <mangix> Hmm what's a good image hosting place?

09:13 <mangix> Oh this one I can't. You'll see.

09:14 <ynezz> github? :p

09:15 <ynezz> you can have images in your gist

09:16 <mangix> Didn't know that.

09:16 <mangix> Archer C7v3 https://imgur.com/a/O4M8YWs

09:18 <rsalvaterra> mangix: That's pretty standard mini-PCIe. Yes, the card is wider, but the screws are in the standard location (for a long card, of course).

09:18 <mangix> The card is wider than on the v2, which is already wide.

09:18 <mangix> Note how ALL the anten as connect to it.

09:19 <mangix> Also note that serial connector came stock.

09:19 <mangix> Erm pins.

09:20 <nitroshift> rsalvaterra, mangix, i remember putting 2 ath9 mini-pcie cards in the wrt1900ac v1 instead of the crappy mwlwifi ones, best single device i had at the time

09:21 <nitroshift> unfortunately, all other wrt devices came with soldered radio chips :(

09:21 <mangix> nitro shift: I remember seeing that frankencard. One PCB two pcie connectors.

09:21 <rsalvaterra> mangix: So, you have an on-board 2,4 GHz ath9k and a QCA9880 for 5 GHz only. The card contains signal mixers to combine the 2,4 and 5 GHz signals in a single antenna. Not usual, but not really weird either.

09:22 <nitroshift> brb, work :|

09:23 <mangix> rsalvaterra: ...wow. I didn't realize there were no extra metal antenas like on the v2.

09:24 <mangix> Makes sense now.

09:26 <rsalvaterra> mangix: You could always get some signal mixers like the Omnia has… if they sold them separately. :P

09:26 <mangix> Funny. I tried to find those online. Failed.

09:27 <rsalvaterra> mangix: I believe everyone has. They're incredibly useful on their own.

09:27 <rsalvaterra> They really should manufacture and sell them separately.

09:27 <mangix> Maybe I should ask them :)

09:28 <rsalvaterra> (Yes, the schematics are open, but I don't really have a PCB manufacturing plant in my bedroom. Yet.)

09:28 <mangix> I'm sure they have extras :)

09:29 <rsalvaterra> mangix: Last time I checked, to buy them you had to prove you owned a Turris Omnia.

09:30 <rsalvaterra> And they were insanely expensive (about 15 € each, excluding shipping).

09:30 <mangix> ...wow

09:32 <rsalvaterra> It's crazy, I know. CZ.NIC would make a fortune just selling signal mixers at a fair price (say, less than 5 € each).

09:32 <plntyk> rsalvaterra, arent most ppl using those cheap jlcpcp stuff ? youtubers like https://www.youtube.com/watch?v=PCB8nv4fatc

09:33 <plntyk> i always see those cheap pcp ads on those electronic vids

09:33 <aparcar[m]> I think the linksys 8450 got more LEDs than the belkin one, also the websites describes the former to cover a larger area. Is that just marketing?

09:33 <plntyk> *pcb*

09:33 <plntyk> not the drug

09:34 <rsalvaterra> Hmm… Yeah, I've seen ads for PCBWay… I have no idea how much it would cost, though.

09:35 <rsalvaterra> These guys… https://www.pcbway.com/

09:40 <plntyk> "A 750 MHz to 3 GHzTunable Narrowband Low-Noise Amplifier" interesting tech - but one probably has to do evaluation etc.

09:40 <plntyk> and probably re-certification for FCC/EU

09:46 <f00b4r0> i can vouch for JLCPCB. Been very happy with them

10:11 <russell--> i can dd it by hand, but that's a little awkward

10:13 <russell--> aha, /etc/hotplug.d/firmware/

10:13 <rsalvaterra> russell--: 16 MiB flash hack for the WDR3600? That might interest me… :P

10:13 <rsalvaterra> Where can I see the diff? :)

10:16 <russell--> well, a long time ago i email'd it to openwrt-devel, but it was rejected because openwrt doesn't support mod'd hardware

10:18 <russell--> 2019-03-14 was the email

10:19 <rsalvaterra> russell--: Of course it was, and I fully agree. It doesn't make any sense to officially support modified hardware. :)

10:24 <russell--> http://lists.openwrt.org/pipermail/openwrt-devel/2019-March/021944.html

10:24 <russell--> not quite the same today

10:28 <russell--> somehow lost the change to the hotplug script during the rebase, fixed up and works again

15:17 <luxim> Hello everyone, question for the more experienced developers here: does anyone have any pointers about how to port OpenWrt to a new CPU architecture and SoC? I have a GNU toolchain setup, but I can't find any info about the modifications needed to add a new target to the image builder.

15:20 <PaulFertser> luxim: you start with OpenWrt git tree, not the image builder. The IB is not even compiling anything.

15:20 <PaulFertser> luxim: so clone the repo, look inside target/ ; then you can pick one that was recently added and check git log for it.

15:22 <PaulFertser> luxim: e.g. cb07269988cd3be7cbbd3278081c5688ae8d7616

15:22 <PaulFertser> That's to get an overview of what it takes. And you should be using current code if you need more specific examples.

15:26 <luxim> PaulFertser: Awesome, this is a really helpful starting point, thank you

15:33 <PaulFertser> luxim: good luck, hope you enjoy OpenWrt

15:51 <Tapper> luxim what device and CPU?

15:51 <Tapper> Just out of intrest

15:51 <Grommish> He left already. I wa going to ask the same :)

15:52 <Tapper> lol

19:01 <mangix> Awfully quiet in here...

20:07 <aparcar[m]> mangix: can you review this DPIC fPIC thing?

20:38 <mangix> seems this device uses FIT images...

20:57 <danijeltudek> hi, let me try here and on mailing list, since i didn't get a lot of response on forum and in the github pull request

20:58 <danijeltudek> while working on support for mikrotik rb2011, the NAND issue on ath79 mikrotiks was brought up, which was discussed multiple times already, here, on the forum and in pull requests

20:59 <danijeltudek> so i was able to re-add support for yaffs2, limited to mikrotik subtarget, and it appears to be working fine, but some testing by people who have such devices with bad blocks would be needed, and a word from maintainers if this approach would be acceptable

20:59 <danijeltudek> IMO, this is the best we can do with not a lot of effort

21:00 <danijeltudek> i won't repeat too much here, i sent a more detailed message on the mailing list: http://lists.openwrt.org/pipermail/openwrt-devel/2021-March/034414.html

21:17 <aparcar[m]> mangix: https://github.com/openwrt/openwrt/pull/4006

22:04 <mangix> aparcar[m]: looks fine.

22:09 <rsalvaterra> No volunteers for bumping 5.10? :P

22:15 <aparcar[m]> rsalvaterra: what do you mean?

22:15 <aparcar[m]> Isn't it there already?

22:18 <rsalvaterra> aparcar[m]: Still at 5.10.23, but gregkh is already at 5.10.25 (and 5.10.26 at -rc1).

22:19 <rsalvaterra> I'll probably do it, if no one gets to it before, but it takes forever on this machine.

22:19 <mangix> rsalvaterra: want ssh access to mine?

22:20 <Hauke> rsalvaterra: when I need compile resources I rent someting in the hetzner cloud

22:20 <rsalvaterra> mangix: Thanks, but too much responsibility. :) Besides, I'm switching to the Haswell when I get the external drive case (still in transit, AliExpress takes forever).

22:21 <mangix> why Haswell?

22:21 <rsalvaterra> mangix: It's my fastest machine, at the moment.

22:22 <rsalvaterra> This: https://www.gigabyte.com/Mini-PcBarebone/GB-BXi7-4770R-rev-10#ov :P

22:22 <mangix> oh you have it. ok.

22:24 <zorun> if you need a shared machine to build something on: https://cfarm.tetaneutral.net/

22:24 <zorun> I make sure all dependencies are there to build openwrt :)

22:25 <rsalvaterra> zorun: Good to know, thanks! :)

22:26 <rsalvaterra> Anyway, I have the little cube just sitting here, for now… I don't want to stress the internal SSD with builds, so I'll use an external drive.

22:27 <mangix> that website looks...quite useful.

22:27 <mangix> zorun: is the M1 device the only macOS device?

22:28 <zorun> mangix: yes, it's the first one, and frankly it's a pain to manage (it doesn't integrate well)

22:30 <zorun> but having a M1 machine is nice

22:30 <pkgadd> rsalvaterra: I've built with 5.10.25 yesterday (ath79/ ath79-tiny, ipq806x), the trivial way of not rebasing the patch sets - worked fine

22:32 <rsalvaterra> pkgadd: You haven't refreshed the patches? You're brave! :P

22:32 <pkgadd> that works often enough

22:33 <pkgadd> I'm sure refreshing will fix up some newly gained fuzz, but GNU patch is smart enough to deal with that on its own (in this case)

22:34 <rsalvaterra> zorun: Can't wait to see that M1 running Linux… ;)

22:34 <pkgadd> admittedly, I did look at the pending 5.4.106/ 5.4.107 PRs before to confirm that those only had to deal with some fuzz as well

22:38 <zorun> rsalvaterra: well, you saw this, right? https://corellium.com/blog/linux-m1

22:42 <rsalvaterra> zorun: Forget Corellium work. It's too hacky and ugly to live.

22:43 <rsalvaterra> zorun: https://asahilinux.org/2021/03/progress-report-january-february-2021/

22:47 <mangix> zorun: aparcar[m] was curious about an M1 device

22:50 <rsalvaterra> What worries me the most about the M1 is its inability to boot from external media… if the (soldered) internal SSD dies, it's the end.

22:51 <mangix> that's a reality apple device owners have dealt with for a long time.

22:51 <mangix> it's not just the m1

22:51 <Nick_Lowe> https://appleinsider.com/articles/21/01/03/how-to-boot-an-apple-silicon-mac-from-an-external-drive ?

22:55 <rsalvaterra> Nick_Lowe: The boot process starts by copying the kernel to the internal SSD.

22:58 <Nick_Lowe> Ouch

22:59 <Nick_Lowe> Good to learn

22:59 <rsalvaterra> Nick_Lowe: Yeah, nasty surprise.

22:59 <rsalvaterra> (I'm still looking for the source where I read this…)

23:00 <rsalvaterra> https://twitter.com/marcan42/status/1348169762468110338

23:01 <rsalvaterra> But i've seen a more detailed explanation, don't remember where.

23:02 <Nick_Lowe> I'm holding out with a 2015 and 2019 MBP, the older Macs are 3x3:3, the new 2x2:2

23:02 <Nick_Lowe> There's also loads of driver bugs

23:03 <Nick_Lowe> https://www.intuitibits.com/2021/02/05/whats-going-on-apple-part-2/

23:04 <rsalvaterra> Heh… I hate Apple and all that it represents with a passion. But I'm a sucker for non-x86 architectures.

23:05 <stintel> rsalvaterra: I feel ya

23:05 <stintel> can'

23:06 <stintel> can't wait for all this covid bs to relax a bit, so I can get my Sparc in my parents' place and throw it in my rack, close to the Power8 :)

23:06 <rsalvaterra> stintel: I know you do. :)

23:06 <stintel> and I'm really loooking forward to play with the HiFive Unmatched

23:07 <rsalvaterra> stintel: POWER8…!

23:08 <stintel> I was looking at Itanium systems on ebay at some point but damn these cost a ton still

23:09 <rsalvaterra> stintel: I've been drooling over the Itaniums for years, but they're a complete dead-end. They've been dropped from GCC, I believe.

23:10 <rsalvaterra> And they're still obscenely expensive.

23:10 <stintel> I believe even from the kernel

23:10 <rsalvaterra> Even POWER7 is cheaper and would run rings around the Itanium.

23:12 <stintel> POWER8 stuff also seems rather expensive on ebay :P

23:12 <stintel> compared to what I paid

23:12 <stintel> I knew I should have ordered 2!

23:12 <Grommish> Hey all

23:12 <Grommish> rsalvaterra: Do you have a PPC device? :D

23:12 <mangix> genis

23:13 <mangix> ccache caches at $HOME/.ccache by defau;t

23:13 <rsalvaterra> Grommish: I have an iBook G4 and a Power Mac G5 (half dead, boots, but hangs after a while, haven't powered it on since last July).

23:14 <Grommish> Ah, I just patched rust to allow for powerpc toolchains but I've not heard of a PPC device

23:14 <Grommish> So I perked up whe n I saw you say that LD

23:15 <rsalvaterra> Grommish: Speaking of which, no hangs on your EdgeRouter? :)

23:16 <Grommish> No but then I only ran it a few days with no real load

23:17 <rsalvaterra> Grommish: My RM2100 also has no issues, and I push it quite a bit, now and then (BitTorrent).

23:18 <Grommish> I've been focusing on Suricata 6 and rust. both of which I think are mostly finished :)

23:19 <Grommish> if you feel like a 5-6 hour compile, you would make the rust toolchain :D

23:19 <Grommish> err could

23:19 <rsalvaterra> And I still had no comments on my jffs2 zstd patch… I wonder how long I should wait before pinging…?

23:19 <rsalvaterra> (Upstream patch, not OpenWrt, of course.)

23:20 <Grommish> Upstream is just some nebulous scary place where everyone knows more than I do.. and I"m not wearing shoes for some reason

23:21 <rsalvaterra> Grommish: 5-6 hours, that's… awful. :P

23:21 <Grommish> Well.. On your machine it'll probably be that long

23:21 <Grommish> but it only has to be done once ;p

23:21 <stintel> I've been running suricata before but the APU2 is way to slow for that :P

23:22 <stintel> I'm wondering what that CAVIUM CN6640-SNIC10E-1.1-G can handle

23:22 <Grommish> stintel: i'm not sure how practical any of it is, for sure.. i wanted it on my Shield, but that required rust, etc etc

23:22 <Grommish> I run it fine on the CN7020AAP1.2

23:22 <stintel> Grommish: yeah I stopped working on it when I read about the rust requirement

23:22 <Grommish> stintel: *nod* I wasn't smart enough to know better ;p

23:23 <Grommish> but I've got Surcata 6.0.2 running on the ER10x

23:23 <stintel> what device is that CN7020AAP1.2?

23:23 <Grommish> which just sounds odd all around haha

23:23 <stintel> ah, ER10x ?

23:23 <Grommish> Itus Networks Shield

23:23 <rsalvaterra> Grommish: I don't find upstream scary at all. Yes, everyone there is way smarter than I'll ever be, but they're also nice and supportive, from my experience. :)

23:23 <Grommish> The ER10x is a ramips

23:24 <Grommish> and wulfy on the Forum is testing aarch64 on a Rpi4 for me

23:24 <Grommish> I built the rust toolchain and compiled the ipk without issue, they are going to see if it actually runs

23:24 <stintel> dualcore 1GHz, probably even slower than the APU2

23:24 <stintel> now that I've upgraded from 200/120 to 1000/600, I really need something beefier

23:24 <Grommish> Dualcore 1Ghz mips64, 1GB Ram, more than enough storage.. I get 920/245 down/up throughput on it

23:25 <stintel> and I keep failing to get the WatchGuard Firebox M300 running OpenWrt

23:25 <Grommish> but I don't have a switch chip to deal with either, it's just 3 straight ethernet ports

23:25 <stintel> the APU2 can handle 1000/600 fine but not at all with SQM, which I definitely need on this connection

23:25 <Grommish> was an amazing box, but they only made a few hundred

23:28 <stintel> the M300 is a quadcore 1.5GHz PPC64

23:29 <stintel> it actually boots OpenWrt but I fail to get any of the network interfaces working

23:31 <Grommish> My only outstandign issues right now are dsa driver fore rtl8367rb, or getting the swconfig to work with all the ports on the rtl8367rb, rather than only 4 of the 5

23:32 <Grommish> and getting the LEDs on the switch section to work

23:37 <stintel> maybe I should try harder to convince WatchGuard to supply the source code

23:37 <Grommish> What is WatchGuard?

23:37 <stintel> the company that built the Firebox M300 I'm talking about

23:39 <Grommish> Ah
