Summary: When possible, switch syscall(2)/__syscall(2) calls to direct calls of internal libc symbols. Add a new function to detect address of a libc symbol of a function that could be intercepted. With the address detector in GetRealLibcAddress(), an optional interceptor of libc call will be bypassed. The original approach with syscall(2)/__syscall(2) wasn't portable across supported ABIs and CPU architectures. The indirect syscall interface is also a candidate for removal in future revisions of NetBSD, as the C language ABI is not a good domain for serialization of arbitrary functions arguments. Switch the following functions to libc calls: - internal_mmap() - internal_munmap() - internal_mprotect() - internal_close() - internal_open() - internal_read() - internal_write() - internal_ftruncate() - internal_stat() - internal_lstat() - internal_fstat() - internal_dup2() - internal_readlink() - internal_unlink() - internal_rename() - internal_sched_yield() - internal__exit() - internal_sleep() - internal_execve() - NanoTime() - internal_clock_gettime() - internal_waitpid() - internal_getpid() - internal_getppid() - internal_getdents() - internal_lseek() - internal_sigaltstack() - internal_fork() - internal_sigprocmask() - internal_sysctl() - internal_sigemptyset() - internal_sigfillset() - GetTid() - TgKill() This revision leaves room for refactoring in subsequent commits.
