node 🚀 - (bug) on arm and mipsel

@addaleax do you know why it happens?

p3x-robot on 27 Jun 2018

@addaleax here is the error
https://github.com/nodejs/node/blob/v10.5.0/src/node_platform.cc#L262
Some asserting.

p3x-robot on 27 Jun 2018

@p3x-robot Are you using the builds from https://nodejs.org/en/ ? Can you get a stack trace or similar for that assertion (e.g. using gdb)?

addaleax on 27 Jun 2018

I do not have gbp , i am on a router. but it is only since the new threads.
I tried DEBUG=*, but not working.

p3x-robot on 27 Jun 2018

i build from here:
https://github.com/nxhack/openwrt-node-packages/tree/master/node

p3x-robot on 27 Jun 2018

i get this error here:
https://github.com/nodejs/node/blob/v10.5.0/src/node_platform.cc#L262

p3x-robot on 27 Jun 2018

@p3x-robot You might still be able to get a core dump in some way, even if you’re on a router?

addaleax on 27 Jun 2018

@addaleax I could come up like this:
https://cdn.corifeus.com/archive/node.1530108405.24874.6.core

can it help?

p3x-robot on 27 Jun 2018

@addaleax Here is some info:

Hi @p3x-robot

I do not know if this information is useful. This is the place I can do for now.

warning: exec file is newer than core file.

@p3x-robot The executable you passed to gdb should match the one used to generate the core dump – is that the case here? If yes, the information in there is not all that useful, sorry … thread apply all bt might give a bit more. But my gut feeling is that that warning is helpful here, and you want to generate a new core dump with exactly that executable first.

addaleax on 28 Jun 2018

how can i create a core dump?

p3x-robot on 28 Jun 2018

@p3x-robot the way you did it before, you run the executable and wait for the crash to happen

addaleax on 28 Jun 2018

this is good?

i check if i can careat a a debug build.

p3x-robot on 28 Jun 2018

@addaleax ok building a debug version and then give you the core dump gdb info.

p3x-robot on 28 Jun 2018

i cannot build a debug nodejs on arm . damn it.

p3x-robot on 28 Jun 2018

trying hacking.

@addaleax do you think 10.6 is fixing this update?

p3x-robot on 5 Jul 2018

@nxhack This does not look like the same crash reported originally here? Also, for your bug, running the code under strace might give more helpful information if that’s possible, or stepping through a call that contains an actual crash

I will test v10.6.0 on LEDE(openwrt)-17.01.x environment. It will take some time. please wait a moment.

nxhack on 6 Jul 2018

@addaleax fwiw i recently ran into a similar issue in my own runtime where v8 was calling into the platform (specifically GetBackgroundTaskRunner) before Isolate::New returns, and therefore before the isolate can be registered with the platform. my solution was to auto-register an isolate with my platform if it doesn't exist when isolate data is needed.

devsnek on 6 Jul 2018

it might be that LEDE will not be supported on NodeJs 10.5 or above, it is to much hassle and OpenWrt is almost opening the stable doors.

@devsnek Are you by any chance using a V8 version that is newer than Node’s? You’d be interested in something like https://github.com/v8/node/pull/71 for your runtime then (but it doesn’t have anything to do with this bug, I think)

nxhack on 9 Jul 2018

@nxhack do i have to use the newer gcc and binutils or CONFIG_ADVISE_SYSCALLS=yes is enough?

p3x-robot on 9 Jul 2018

@p3x-robot @nxhack I’m surprised that the lack of madvise is a real issue here. Can you try to confirm that the call site is ReclaimInaccessibleMemory in deps/v8/src/base/platform/platform-posix.cc? If so, what happens if you comment out the function body and replace it with return 0;?

addaleax on 9 Jul 2018

@addaleax
OK. I will test it. Please give me a time.

@nxhack Can you check that this works too? If so, I’d suggest that either you or me will try to patch V8 with it:

   if (ret != 0 && errno == EINVAL) {

addaleax on 10 Jul 2018

@addaleax @nxhack does it mean we will not need any in the kernel? like newer gcc, binutils and the Enable madvise/fadvise syscalls settings? That would be totally perfect.

p3x-robot on 10 Jul 2018

i suggest if @nxhack can hack it, then maybe we could put it into nodejs, is that possible?

p3x-robot on 10 Jul 2018

👍1

@p3x-robot Yes, that would mean that we work around the kernel’s lack of madvise. I don’t think this should be a real issue, but we may just need for the V8 CL in that case.

Edit, V8 CL: https://chromium-review.googlesource.com/c/v8/v8/+/1131943

addaleax on 10 Jul 2018

@addaleax @nxhack, when is rested, can best do it.

p3x-robot on 10 Jul 2018

but, if too much patching for V8 :-1: , I will do it myself, to add to the kernel. dunno, which is the best, maybe @nxhack can give more options, how we should do it.

p3x-robot on 10 Jul 2018

@addaleax

Edit, V8 CL: https://chromium-review.googlesource.com/c/v8/v8/+/1131943

Worked. LGTM

It applied to my openwrt custom node.js package repository. Please test.

@nxhack ok, building. No change, as i understand, the patch is in v8, not kernel, thanks, let you know the results, 15 hours

p3x-robot on 11 Jul 2018

@addaleax should i close this? from the mips and arm is working perfectly.

p3x-robot on 12 Jul 2018

@p3x-robot @nxhack If you want, we can backport that patch to the “official” Node.js 10 repository. But since you’re maintaining your own set of patches on top of Node anyway, that’s unnecessary, right?

addaleax on 13 Jul 2018

@addaleax
I hope you will backport this patch.
Thank you.

nxhack on 14 Jul 2018

guys, should i close this issue? looks like they do not backport this patch.

p3x-robot on 26 Oct 2018

@p3x-robot It is taken in v11.0.0.

nxhack on 26 Oct 2018

awesome, closed... thanks...
