Are you using a custom rom? Are you rooted?

You could try upgrading to the android-7 repo by running termux-upgrade-repo and then trying again

Grimler91 on 19 Jul 2019

No, I'm using non rooted Samsung Galaxy note 8.

I tried termux-upgrade-repo, but still the same problem.

ourarash on 19 Jul 2019

I was having this problem when I was using a particular custom rom for the galaxy s8+. The bad system call was kill(), which was weird cause it shouldn't be blocked according to the syscall blacklist, but I'm not a seccomp expert so maybe I'm missing something.
The problem disappeared after I flashed another rom so I figured it was a problem with that particular rom.

Could you install gdb and this debug build of nodejs: https://grimler.se/nodejs-dbg_12.4.0-1_aarch64.deb
And post the output of
gdb -ex=run -ex=bt --args npm install https://github.com/ourarash/get-cursor-position.git
to confirm it's the same issue as I've encountered before?

Grimler91 on 19 Jul 2019

I get this for installing the debug node package:

Building dependency tree
Reading state information... Done
E: Unable to locate package https://grimler.se
E: Couldn't find any package by glob 'https://grimler.se'
E: Couldn't find any package by regex 'https://grimler.se'
$

Does this command work for you?

npm install https://github.com/ourarash/get-cursor-position.git

I get this for installing the debug node package:

Debug package should be installed via:

wget https://grimler.se/nodejs-dbg_12.4.0-1_aarch64.deb
dpkg -i nodejs-dbg_12.4.0-1_aarch64.deb

Not sure why this package is not compatible with Termux. Even this doesn't work for me:

npm install get-cursor-position

ourarash on 19 Jul 2019

Does it require specific nodejs version ?

xeffyr on 19 Jul 2019

Does it require specific nodejs version ?

I can install it on my mac lapotp using:

node -v
v8.11.4

I think there is an issue in the C++ compile during the package install that is not related to node.

ourarash on 19 Jul 2019

that is not related to node.

Related to node headers.

xeffyr on 19 Jul 2019

@Grimler91 It getting killed due to __NR_setgid32.

nodejs-lts works better (only linking error):

Happens because objects are not compiled with -fPIC.

@xeffyr

It getting killed due to __NR_setgid32.

You got that on arm? Seems like __NR_setgid32 should be only blocked on arm and x86 according to https://github.com/aosp-mirror/platform_bionic/blob/pie-dev/libc/SECCOMP_BLACKLIST_APP.TXT

Grimler91 on 19 Jul 2019

On x86 of course.
My aarch64 device running Android 9 but has SELinux set to permissive permanently, so I don't have any "bad system call" errors.

xeffyr on 19 Jul 2019

Looked strace output on my aarch64 device, it seems setgid() is really used.

It still gives me bad Bad system call with this. I ran it on Galaxy Note 8, non-rooted.

It won't fix bad system calls.
Just will allow to install get-cursor-position without errors on devices running lower Android versions or have SELinux in permissive mode (permissive mode also disables seccomp).

Is there any workaround for this? Any plans to be fixed? Thanks!
