Purpose

As reported in Lind-Project/lind-wasm-apps#161, nginx fails when setgid returns a non-zero value.

>> cat lindfs/var/log/nginx/error.log 
2026/03/26 16:17:37 [emerg] 3#0: setgid(65534) failed
2026/03/26 16:17:37 [alert] 2#0: worker process 3 exited with fatal code 2 and cannot be respawned

Upon investigation, nginx calls setgid which goes through this trace

  1. lind-wasm/src/glibc/sysdeps/unix/sysv/linux/setgid.c

    Lines 23 to 29 in ebbe66c

    int
    __setgid (gid_t gid)
    {
    #ifdef __NR_setgid32
    return INLINE_SETXID_SYSCALL (setgid32, 1, gid);
    #else
    return INLINE_SETXID_SYSCALL (setgid, 1, gid);

  2. lind-wasm/src/glibc/sysdeps/unix/sysv/linux/i386/sysdep.h

    Lines 320 to 329 in ebbe66c

    #define INTERNAL_SYSCALL(name, nr, args...) \
    ({ \
    register unsigned int resultvar; \
    INTERNAL_SYSCALL_MAIN_##nr (name, args); \
    (int) resultvar; })
    #define INTERNAL_SYSCALL_NCS(name, nr, args...) \
    ({ \
    register unsigned int resultvar; \
    INTERNAL_SYSCALL_MAIN_NCS_##nr (name, args); \
    (int) resultvar; })

The register unsigned int resultvar; is uninitialized which returns a garbage value back to nginx.

Fix

Initialize resultvar as 0 solved the problem

As I was reading more about how we handle no-op syscalls in modified glibc, it would be more coherent and clean using the INLINE_SYSCALL_CALL macro to stub this kernel path which was mistakenly missed instead of fixing the header files of a specific port.

@rennergade As per my understanding, we use

lind-wasm/src/glibc/sysdeps/unix/sysdep.h

Line 228 in 4e2fb7e

#define INLINE_SYSCALL_CALL(...) 0
to stub no op syscalls in lind-wasm typically.
However, for setgid(), we were using

lind-wasm/src/glibc/sysdeps/unix/sysv/linux/setgid.c

Lines 26 to 29 in 4e2fb7e

#ifdef __NR_setgid32
return INLINE_SETXID_SYSCALL (setgid32, 1, gid);
#else
return INLINE_SETXID_SYSCALL (setgid, 1, gid);

which returns a garbage value instead of a 0.

This PR attempts to fix the root cause of that garbage value and effectively starts returning 0 even from INLINE_SETXID_SYSCALL.

how's INLINE_SETXID_SYSCALL related with INTERNAL_SYSCALL and INTERNAL_SYSCALL_NCS in your change?

@qianxichen233 INLINE_SETXID_SYSCALL calls INLINE_SYSCALL which, for our i386 port, calls

lind-wasm/src/glibc/sysdeps/unix/sysv/linux/i386/sysdep.h

Lines 320 to 329 in 1bed551

#define INTERNAL_SYSCALL(name, nr, args...) \
({ \
register unsigned int resultvar; \
INTERNAL_SYSCALL_MAIN_##nr (name, args); \
(int) resultvar; })
#define INTERNAL_SYSCALL_NCS(name, nr, args...) \
({ \
register unsigned int resultvar; \
INTERNAL_SYSCALL_MAIN_NCS_##nr (name, args); \
(int) resultvar; })

that has an uninitialized variable called resultvar

I looked into this a little bit, the correct call path is __setgid calls __nptl_setxid which calls INTERNAL_SYSCALL_NCS since SINGLE_THREAD_P is turned off by default in lind environment

Though the call path isn't really matter. The actual issue behind it is that INTERNAL_SYSCALL_MAIN_NCS_##nr and INTERNAL_SYSCALL_MAIN_##nr was inline assembly and was removed in early work of lind-wasm: Lind-Project/glibc@7d0f3db#diff-cb58b6549d17ee4ac47ea4b2b1f2a54df66ef06cdf611f24936b1890c813db93

In its original glibc design, INTERNAL_SYSCALL_MAIN_NCS_##nr is supposed to set the resultvar, but since INTERNAL_SYSCALL_MAIN_NCS_##nr right now resolves to nothing, resultvar is left uninitialized.

This is basically the same issue as #709, all the INTERNAL_SYSCALL family in glibc is broken and we should replace them with lind_debug_panic instead. We do not really prefer to have glibc syscall code calls into INTERNAL_SYSCALL family macros as they are all just un-handled legacy code, having a very delibrate control over all glibc syscalls is our final goal.

For this PR, I think first we shouldn't still redirect to setgid to INTERNAL_SYSCALL. make it directly return 0, or -1 with ENOSYS or whatever we like.

The fix for INTERNAL_SYSCALL can be a valid temporary fix before #709 is fixed. I'd prefer to change it to -1 by default though, but might break a lot of existing things, since previously INTERNAL_SYSCALL family is always returning a slient success for the syscall while actually not performing any action, changing to -1 might change the execution routine for a lot of code and might break something. So maybe try to make it return -1 first, and if make test or other thing breaks, then we can keep to use 0 for now

@Yaxuan-w What I meant is do we merge this for now and if changes are required later, we could do it. This PR essentially fixes the issue of uninitialized resultvar and the fix here is to return 0. The later discussions mention about refactoring INTERNAL_SYSCALL in all cases where it is invoked. We could do that as a future work.

@rishabhBudhouliya With the current changes you have made to this PR, does nginx work? If so, we could merge this.
