hi,
In fact, I post this question to glibc but no response. Hope you guys here can help me out.
I am trying to figure out the system call from user space to kernel
space. So, I read glibc wrapper first. But I cannot figure out the
exact meaning of INTERNAL_SYSCALL for execve system call on IA32 arch.
In this macro, which function will be called by the following assmebly
code ""call *%%gs:%P2\n\t"? (code is in glibc sysdeps/unix/sysv/linux/i386/sysdep.h)
Is there anyone can help me clarify it?
Thanks,
Neo
