04:59 <djfe> hauke: I see thanks for explaining and retesting, someone at our Freifunk Community owns a td-w8970b v1 and wanted to flash it. I'll take a look if I can get the patch working. Without the patch the device runs fine, right?

05:05 <djfe> something else: If a Radio runs on the mmc (bus?) and the address switches randomly between mmc0 and mmc1 on reboot, what can be done? I thought about wifi path migration but that's only a workaround. 21 is working fine, so my guess is either the switch to kernel 5.10 or 5.15 introduced this https://github.com/openwrt/openwrt/issues/12237

07:33 <oliv3r[m]> <hauke> "oliv3r: the 7z sources are not..." <- yeah, it's nasty :( but what can we do :(

07:45 cbeznea has joined #openwrt-devel

08:04 <jow> Znevna: you can use the `graph` object to inspect the current rrd data tree and decide which definition to use based on that, see this ocmmit as example: https://github.com/openwrt/luci/commit/9f321b831f41b73554819ac54e308dfa3677ab45

08:06 <Znevna> doesn't that encounter the same issue with files looking like this? power-watt-ups.rrd

08:06 <jow> var types = graph.dataTypes(host, plugin, plugin_instance);

08:07 <jow> if (types.indexOf('watt-ups')) { return definition_with_watt_ups; } else { return original_definition; }

08:07 <jow> (indexOf(...) > -1) actually

08:08 <Znevna> ok I'll try messing with it later :P thanks

08:08 <jow> so the idea is to look which files are there, then return proper definitions based on that

08:08 <jow> and it probably shouldn't be if/else but a series of if() guards

08:09 <jow> since theoretically both power-ups and power-watt-ups could exist at the same time

08:09 <jow> or neither

08:09 <jow> ah now, sorry

08:09 <jow> just looked at the .c source you linked

08:09 <jow> it's either -watt-ups or -ups

08:10 <Znevna> I have them both for some reason

08:10 <Znevna> -ups is is VA and -watt-ups is in W

08:11 <jow> yeah I misinterpreted the if/else if in the .c source

08:11 <jow> it's part of a loop iterating over all gauges

08:11 <jow> so it can be both after all

08:11 <Znevna> but the current nut.js can't handle -ups and -watt-ups beeing a part of power

08:11 <Znevna> because of that extra - I thik

08:11 bluew has quit [Ping timeout: 480 seconds]

08:11 <Znevna> think*

08:11 <jow> can you pastebin the output of `find /tmp/rrd` ?

08:12 <jow> just want to see how it's structured

08:14 <Znevna> originally like this: https://paste.debian.net/plainh/cd9fd06e

08:16 <Znevna> but I've patched the collectd nut.c https://paste.debian.net/plainh/e6147723

08:16 <Znevna> and now it outputs power-watt_ups.rrd :P

08:16 <jow> what unit is the non-watt char in?

08:17 <jow> *chart

08:18 <Znevna> VA ?

08:26 <jow> thanks

08:26 <jow> http://sprunge.us/funT6X

08:26 <jow> that would be my approach (without any collectd modifications)

08:28 <Znevna> I see power: [ "watt-ups"] ... options: { power_ups .. will that work?

08:29 <jow> ah right. Well it would still work, just the options would not be applied

08:29 <jow> they option key should be `power_watt_ups`

08:30 <Znevna> yeah that's where it doesn't work

08:30 <Znevna> :P

08:33 <jow> define not work?

08:33 <jow> broken picture symbol or chart label with slashes in it?

08:35 <jow> ah wait, I see. The `watt-ups` is not a data type but a data isntance

08:36 <jow> the type is `power` with two instances `ups` and `watt-ups`

08:39 <jow> Znevna: http://sprunge.us/7DAyX7

08:40 <Znevna> sorry busy with work too

08:40 <Znevna> I'll try that !

08:40 <jow> yeah np. just drop me a note if it works, I'll push it then

09:38 lmore377 has quit [Remote host closed the connection]

09:39 <kabel> anyone has experience with rwt88 / rtw89 wifi cards on openwrt? are the drivers stable? do they work nicely? are they fast?

09:40 lmore377 has joined #openwrt-devel

09:44 <Znevna> jow: it seems to work fine! is there any way we can check for missing .rrd files and don't try to generate graphs for those missing .rrd files?

09:45 <Znevna> as mentioned in the forum by someone too: https://forum.openwrt.org/t/broken-rrdtool-graphs-for-collectd-mod-nut-pluging-when-ups-doesnt-support-all-features/156246/2

09:45 <Znevna> and thank you! :D

09:45 <ukleinek> kabel: I don't know about the state in openwrt, but a colleage recently worked on the driver upstream

09:46 <ukleinek> kabel: and re: "do they work nicely?": No, they are usb wifi adapters

09:50 <jow> Znevna: yeah, all those other `definitions.push()` calls basically have to be wrapped in an if() condition

09:55 cbeznea has quit [Quit: Leaving.]

09:55 <Znevna> oooh

09:56 <Znevna> now I see that if watt-ups is missing, it doesn't show the broken graph :D nice!

09:57 <Znevna> so that means that I can add everything that collectd can generate and it will only show what that particular UPS supports

09:58 <PaulFertser> ukleinek: kabel: rtw88 is for PCIe devices, e.g. https://elixir.bootlin.com/linux/latest/source/drivers/net/wireless/realtek/rtw88/rtw8821ce.c#L10

09:58 <PaulFertser> rtw89 too.

10:00 <PaulFertser> https://elixir.bootlin.com/linux/latest/source/drivers/net/wireless/realtek/rtw89/rtw8852ce.c#L73

10:00 <PaulFertser> kabel: in general you should expect any upstream Linux driver to work in OpenWrt the same as it works in any other distro.

10:04 cbeznea has joined #openwrt-devel

10:04 <ukleinek> PaulFertser: I didn't recheck, but then there should be usb variants of that chip.

10:05 <PaulFertser> ukleinek: yes, https://elixir.bootlin.com/linux/latest/source/drivers/net/wireless/realtek/rtw88/rtw8821cu.c#L11

10:06 <PaulFertser> But not for rtw89, at least not upstream.

10:07 <ukleinek> FTR: $(git grep -Eoh 'module_[a-z]*_driver' drivers/net/wireless/realtek/rtw88 | sort | uniq -c) -> 4x usb + 4x pci

10:07 <PaulFertser> kabel: if you're really talking about USB, this community gathers everything essential: https://github.com/morrownr/USB-WiFi

10:09 <PaulFertser> ukleinek: you're counting different drivers though, not the quantity of devices supported ;)

10:11 <ukleinek> PaulFertser: yeah, I'm aware of that. It's the usual "Don't believe a statistic you didn't forge yourself'

10:12 <PaulFertser> :D

10:20 <jow> Znevna: http://sprunge.us/dkVIGQ

10:20 <jow> Znevna: can you give this one a try? It adds runtime checking for all nut graphs

10:30 rmilecki has joined #openwrt-devel

10:34 xback has joined #openwrt-devel

10:43 <Znevna> jow: it looks fine, thank you!

10:45 <jow> Znevna: great, I'll push it then

10:48 <Znevna> it even solves the issue mentioned on the forum, if one of the voltages is missing (input or output) the graph still shows for the remaining voltage definition :P

10:49 <Znevna> this was bugging me for a while, thank you again

10:51 <aparcar[m]> zx2c4: do you consider busybox random implementation as "secure"? https://github.com/brgl/busybox/blob/abbf17abccbf832365d9acf1c280369ba7d5f8b2/shell/random.h#L28

10:52 <aparcar[m]> oops sorry I meant so send the random.c file https://github.com/brgl/busybox/blob/abbf17abccbf832365d9acf1c280369ba7d5f8b2/shell/random.c

11:04 Danct12 has joined #openwrt-devel

11:22 <kabel> PaulFertser, ukleinek: I am not talking about USB, but PCIe. We are interested in testing how these cards would work with Turris Routers. The fact that the drivers are in upstream is certainly a plus, but we have bad experience even with such drivers/firmware (mwifiex, for example). My current experience is that only mt76 cards are reasonable, and I am interested in finding out

11:22 <kabel> whether my list can be extended to these new realtek cards

11:23 <robimarko> You are probably going to need to test them

11:30 <PaulFertser> kabel: rtw88 something card in huawei laptop seems to work reliably as a station, that's as far as my personal experience goes.

11:36 <kabel> PaulFertser, robimarko: very well, thanks

11:39 <PaulFertser> kabel: want me to paste lspci -vv from it?

11:40 <PaulFertser> (I doubt it's really useful as that's just basic testing of sta functionality anyway)

11:41 <zx2c4> aparcar: doesn't look like it's designed to be secure. It's just an linear function

11:42 <aparcar[m]> zx2c4: agree, I wonder how difficult it would be to make it secure using /dev/random
