box64: Otohits segfaults

Hello, This closed-source app segfaults. otohits-app should launch and control otohits-viewer, which is essentially an headless chromium. However it just crashes. My sistem is a Raspberry Pi 4 with standard RaspiOS arm64.

But I suspect most the info grabbing are though syscalls, and I’m not sure everything is wrapped correctly to intercept the calls and redirect correctly.

I have added the missing syscall.

Error: Unsupported libc Syscall 0x78 (120) I have a question: why do you wrap syscalls manually, one at a time, when requested? wouldn’t it be faster to add all syscalls in one go?

Some syscall needs manual wrapping, and I prefer to rely on wrapped libs than syscall, so not that many syscall are needed in fact.

{ 120, __NR_getresgid, 3},

Thanks, I’ll add that later.

Error: PltResolver: Symbol clone(ver 2: clone@GLIBC_2.2.5) not found, cannot apply R_X86_64_JUMP_SLOT 0x7f992446a8 (0x7f98c13f56) in libcef.so

The clone syscall strikes again 😕

Probably not a good sign. I guess it crashed and want to just launch gdb for some backtrace?

After some analysis, I think the crash is due to the lack of vDSO emulation. I’ll try to add that later.
