<Hauke> How do I debug procd when it crashes at bootup?
<pkgadd> Hauke: btw. your mac80211 updates are working fine for me on ipq806x (nbg6817), ipq40x (map-ac2200) and lantiq (bthub5), and build-tested for ath79 (haven't flashed those yet, as those devices aren't in regular use); so ath9k and ath10k appear to be fine
<Hauke> pkgadd: thanks for testing, I am using them currently with mt76

<dangole> Hauke: at this stage is it crashing? no output at all after /sbin/init is executed?
<Hauke> I am using the address sanitizer in my system and it does not work correctly for the init process
<Hauke> just found the log
<Hauke> with some other qemu settings I get it
<dangole> Hauke: interesting... might be interesting to just run procd in a container and have valgrind crunching around it
<Hauke> dangole: I will just try to deactivate it for the init process
<Hauke> it wants to access files in /proc and fails
<dangole> Hauke: and /proc isn't yet mounted?
<Hauke> dangole: no procd mounts it
<Hauke> or /sbin/init
<Hauke> this is currently failing
<Grommish> No VFP support on a SoC means. Softfloat?
<Grommish> specifically armv7 if that makes a difference

<mangix> rofl
<rsalvaterra> WAT
<ynezz> there is a53 compile check as well
<mangix> that's libubox itself
<mangix> not other packages including it
<rsalvaterra> mangix: I fail to see how, you're probably being bitten by something else… :/
<mangix> rsalvaterra: nope. removing include sys/stat.h fixes it
<ynezz> mangix: stat.h:17:19: error: expected identifier or '(' before '[' token
<ynezz> this would be visible as well
<ynezz> it is using same SDK
<ynezz> so probably hnetd does some include/macro foo?
<mangix> who knows
<mangix> all I know is, removing the include from libubox/utils.h fixes compilation
<ynezz> but that's "fix" :)
<mangix> It's suspicious why include sys/stat.h was added
<mangix> musl defines mode_t in alltypes.h
<rsalvaterra> Yeah, but that doesn't explain what's so special about hnetd…
<mangix> dunno, some random package in routing
<jow> that's the problem
<mangix> oh, joy
<rsalvaterra> jow to the rescue. :)
<ynezz> I was just about to paste this https://github.com/sbyx/hnetd/blob/master/src/hnetd.h#L111
<ynezz> :)
<jow> the solution will be moving #include "pa_conf.h" before the __unused define (assuming it does not use __unused itself)
<jow> or #include <libubox/utils.h> before declaring __unused
<jow> so simply speaking, make sure all headers are included and processed before declaring __unused
<ynezz> or just don't declare the __unused and use the __attribute__((unused)) directly
<jow> declaring __unused is fine
<jow> but not when done between two direct or indirect sys/*.h includes
<jow> doing any kind of define between two #include's can cause stuff to blow up
<jow> when name collissions occur
<mangix> interesting....
<jow> best is to defer any user code defines until after the last include
<mangix> C23 adds this as a standard keyword
<ynezz> so have fun
<jow> maybe rename it to ___unused :P
<ynezz> ____unsed to be future proof
<mangix> GCC 10 supports [[maybe_unused]] in C. cool.
<rsalvaterra> Wait, C23? That's 3 years from now. :P
<jow> or __almost_unused
<mangix> clang 11 does not
<jow> __supposedly_unused works too :)
<rsalvaterra> __used_when_the_compiler_isnt_looking
<rsalvaterra> So, it's an upstream hnetd bug, fortunately.
<mangix> hmmm
<mangix> C23 does not go far enough

<mangix> rsalvaterra: openwrt toolchain is GCC8
<rsalvaterra> Yeah, I know.
<rsalvaterra> Did it compile with GCC 9?
<mangix> I don't have GCC9
<ynezz> CI builds with gcc 8,9,10
<ynezz> -- The C compiler identification is GNU 8.4.0
<mangix> ynezz: I'm talking about [[maybe_unused]] in C.

<mangix> hmm auto didn't make it in C23

<rsalvaterra> Totally unrelated, is it normal to see package dependency problems when only the packages feed is selected? :/
<rsalvaterra> It doesn't seem right to have packages depending on LuCI stuff… should be the other way around, no?
<mangix> rsalvaterra: giff example pl0x
<mangix> most of these are from the routing repo
<mangix> What was supposed to happen was routing merging with packages
<mangix> but that got abandoned at some point
<rsalvaterra> Oh, well. It's ugly, but I can live with it. :P

<nbd> Hauke: btw. feel free to drop 300-mac80211-optimize-skb-resizing.patch in your updates
<nbd> i'll re-do it and post it upstream before we merge the mac80211 updates to master
<Hauke> nbd: ok thanks
<Hauke> I haven't seen a problem when testing it
<nbd> functionally your adjustment looks fine
<Hauke> nbd: the change from Johannes was also backported to 4.19 and I would like to add the security updates to the 19.07 stable branche
<nbd> just needs to be re-done for upstream
<Hauke> ok
<nbd> i'm currently working on 802.11->802.3 decap offload
<nbd> will try to take care of that patch afterwards
<Hauke> ok
<Hauke> should it then be possible to forward traffic between the Ethernet and the Wifi without the CPU seeing it?
<nbd> i will work on that as well
<nbd> pablo will send our work on NAT offload (with my rewritten driver for MTK) upstream soon
<Hauke> nice
<nbd> once that's in the tree, i can build on that for eth<->wifi offload
<nbd> it will be supported for mt7622 on the SoC side and 7915 for wifi
<nbd> maybe also 7615 later, not sure how much offload that one supports
<Hauke> ok
<nbd> either way, 7915 will be the first wifi chip to have upstream eth<->wifi offload support
<Hauke> mt7622 should normally be fast enoght to do this in SW
<nbd> for 1500 byte sized packets, the difference between SW and HW is small
<nbd> for smaller packets, offload will help
<Hauke> ok
<nbd> sw performance is currently around 1700-1800 mbit/s under ideal conditions
<nbd> but still lower when sending to more stations at the same time
<nbd> not sure how much of that is sw limitation
<Hauke> 1800MBit/s with 4x4 160 Mhz?
<nbd> 4x4 80 MHz
<nbd> or 2x2 160 MHz
<Hauke> ok
<rsalvaterra> nbd: You mean encapsulation offloading?
<nbd> rsalvaterra: nope
<nbd> encap offload is already done
<nbd> so i'm working on decap now
<rsalvaterra> Hm… interesting.
<rsalvaterra> Yeah, I know ath10k does encap already, at least for some chips.
<nbd> the hw supports it, not sure how much of the code for it is upstream
<nbd> when i worked on the patch, only ath11k had upstream support
<rsalvaterra> But if MT7615 could be supported, it would be really great, since a lot of them are still paired with the underpowered MT7621.

<Hauke> the first mt7621 + mt7915 device is on amazon in Germany

<jow> rr123: it means that the ubus http interface will be wide open, anyone can execute all methods using any random faked sessions id
<jow> rr123: it is a debugging feature, don't enable it unless you develop something
<philipp64> jow: that doesn’t sound good.
<philipp64> jow: so, is it correct that there’s no way to force one start script to only run after another one (on which it depends) has finished initializing?
<jow> philipp64: well there are way, but since the system can't possibly know how "finished initializing" is defined for any potential service, you need to implement this yourself, e.g. by sending a signal or hotplug event
<philipp64> hm….
<philipp64> any good examples to follow?
<philipp64> it’s Bind and ISC-DHCP(D) in this case.
<jow> well you could simply call /etc/init.d/whatever start when the other thing is finished
<jow> and make /etc/init.d/whatever's boot() method a no-op
<jow> or run /sbin/hotplug-call whatever potentially with env vars carrying auxiliary info
<jow> thne have an /etc/hotplug.d/whatever/01-blah which invokes /etc/init.d/qrx restart

<philipp64> jow: question for you… my Bind logs keep filling up with warnings about “Permission denied” when local clients try to do IPv6 lookups (AAA) of domains because my “wan” connection is IPv4 only… Does it make sense to detect whether IPv4 or IPv6 (or both) are configured on “wan”, and pass “-4”, “-6”, or neither (aka “both”) as flags to “named” on startup?

<philipp64> I’m happy to do the PR if it’s the right thing to do.
<jow> why can't those queries be simply forwarded as IPv4 ?
<jow> I bind not doing the standard try-IPv6-fallback-to-IPv4 thing that most clients do nowadays?

<dwmw2_gone> I don't even understand what's going on there
<dwmw2_gone> I can't answer the question "what is the IPv6 address of foo.example.com" because the client isn't asking *over* an IPv6 connection?
<dwmw2_gone> That seems insane.
<philipp64> regarding smtp or Bind?
<dwmw2_gone> smtp is simple enough. Here's a nickel, kid. Get yourself a decent mail server.
<dwmw2_gone> I meant bind.

<zorun> more likely bind tries to reach root servers or other NS servers over IPv6, irrespective of the actual queries
<dwmw2_gone> so? It'll then fall back to Legacy IP if it can't reach them over IPv6.
<jow> permission denies likely comes from the local ip policies then
<dwmw2_gone> That still has *nothing* to do with whether it was a TXT, NS, A, or AAAA record being queried.
<dwmw2_gone> We should note, however, that this month marks the 25th anniversary of RFC1883. A full quarter of a century since IPv6 was published.
<dwmw2_gone> I propose a full overhaul of our documentation to make sure we refer to "Legacy IP" consistently.

<Borromini> :P
matteo| is now known as matteo
<jow> philipp64: do you get "permission denied" as well when you try to ping6 2001:4860:4860::8888 ?
Borromini has quit [Quit: leaving]
<philipp64> Why give an address for an EXTERNAL entity that’s not reachable?
<dwmw2_gone> what makes you think it's not reachable?
<philipp64> jow: affirmative
<dwmw2_gone> Client devices can't have tunnels of their own?
<dwmw2_gone> VPNs?
<dwmw2_gone> split routing?
<philipp64> okay, so what’s the solution to making the “Permission denied” go away?
<zorun> use dnsmasq like everybody else? :-)
<dwmw2_gone> or join us in the 21st century and have IPv6 on your wan :)
<dwmw2_gone> quarter of a century...
<mangix> philipp64: I get replies from that address
<philipp64> dwmw2_gone: not my choice… talk to my ISP.
<dwmw2_gone> You talk to your ISP. Or better still, talk to a better ISP :)
<mangix> 2001 is tunneled, no?

<dwmw2_gone> More seriously, work out where the error is coming from
<dwmw2_gone> if it's just that you don't have a route, you shouldn't get -EPERM.
<dwmw2_gone> If bind is spamming the logs with that, it sounds like a bind bug
<dwmw2_gone> or misconfiguration

<jow> philipp64: what is reported by "ip route get 2001:4860:4860::8888" ?
<jow> that permission denied is an OpenWrt ip policy rule
<jow> it applies to IPv6 traffic that is sent with a wrong source prefix
