SIGSYS crash from pidfd_open blocked by seccomp (kernel 4.4.205 / Android 10 / OnePlus 5_QualcommMSM8998)

Dear guysoft,

First & foremost many many thanks for porting opencode to Android arm and keeping it free for all of us!

May you kindly look into the following when you have some free time: after installing opencode 1.3.13.deb via dpkg -i I see the TUI for a minute or so; and later the opencode crashes with aforementioned SIGSYS crash. The behaviour is similar with 1.3.13_tagfix16. Enclosed you'll find:
• strace -f opencode log
• the output of cat /proc/version
• the output of uname -a just to confirm the kernel, cpu, Android version etc.

If anything else is needed please let me know and many thanks again for all the effort!

strace_F.log

proc_version.log

uname_A.log

So as a 'temporary & non-elegant' workaround I was able to quickly draft the following sigsys_shim.c:

sigsys_shim.c

• Compile within Termux environment with: gcc -shared -fPIC -o libsygsys_shim.so sigsys_shim.c

• To execute: LD_PRELOAD=./libsigsys_shim.so opencode

You can later export this to .bashrc . zshrc (your_shell.rc) with: export LD_PRELOAD=$Your_Termux_Path$/libsygsys_shim.so to make the above permanent.

I can confirm that with ./libsigsys_shim.so 'trick' & latest opencode 1.17.9 everything works as expected for my OnePlus 5@QualcommMSM8998. Might as well for other older kernels and devices.
