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.

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

Lacking vDSO might also cause #97 .

lack of vDSO emulation

FEX has some more detail on vDSO and vsyscall (here and here.)

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?

{ 120, __NR_getresgid, 3},

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.

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

./otohits-viewer now works (but it fails because of missing X display).

Apr 05 '23 09:04 ElDavoo

I have added the missing syscall.

Apr 05 '23 10:04 ptitSeb

After adding also:

{ 50, __NR_listen, 2},
{ 80, __NR_chdir, 1},
{ 288, __NR_accept4, 4},

It almost works!! But it tries doing file operations in /usr/local/bin, which is where box64 is globally installed. How to make the program work in pwd ??

I worked around the path issue by copying the box64 binary in the same dir of the otohits binary and letting it run.
Maybe it's working (I need an X display to test it), only minor issue is it tries to fetch the CPU model and fails (empty string) (on my PC it returns Intel(R) Core(TM) i7-10875H CPU @ 2.30GHz )

Apr 05 '23 10:04 ElDavoo

fetching of cpu info should work, not sure how that program is fetching it. Using CPUID it should just work. If it's greping /proc/cpuinfo it might be buggy, I need to check.

Apr 05 '23 11:04 ptitSeb

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.

Apr 05 '23 11:04 ptitSeb

Things went forward, but they are now difficult to debug.

^C

After "surf is about to start", the program tries to start "otohits-viewer". If that fails, however, you will see a zombie "otohits-app" process until the timeout triggers and the program retries to start it.

This is what it's supposed to happen:

Nothing changes between enabling dynarec or not (dynarec is faster though).

Running ./otohits-viewer by itself, however, seems to work. (it loads a test URL).

To recreate the same environment in my x86_64 laptop and my raspberry, I dockerized the app. I'm attaching the dockerfile so maybe this way debugging will be easier / you can easily get the dependencies (you still need to sign up in the service/have an application key though)
