C++ (Cpp) replace_syscall Examples

Example #1

File: redir.c Project: lb1a/avfs

void cleanup_module(void)
{
	printk(KERN_INFO "redir cleanup\n");
   
	replace_syscall(__NR_chdir,    orig_chdir);
	replace_syscall(__NR_stat,     orig_stat);
	replace_syscall(__NR_lstat,    orig_lstat);
	replace_syscall(__NR_access,   orig_access);
	replace_syscall(__NR_open,     orig_open);
	replace_syscall(__NR_readlink, orig_readlink);
	replace_syscall(__NR_getcwd,   orig_getcwd);

#if NEWVFS
	replace_syscall(__NR_stat64,   orig_stat64);
	replace_syscall(__NR_lstat64,  orig_lstat64);
#endif

#ifdef __i386__
	replace_syscall(__NR_execve,   orig_execve);
#endif

}

Example #2

File: redir.c Project: lb1a/avfs

int init_module(void)
{
	printk(KERN_INFO "redir init (version %s)\n", REDIR_VERSION);

	orig_chdir    = replace_syscall(__NR_chdir,    virt_chdir);
	orig_stat     = replace_syscall(__NR_stat,     virt_stat);
	orig_lstat    = replace_syscall(__NR_lstat,    virt_lstat);
	orig_access   = replace_syscall(__NR_access,   virt_access);
	orig_open     = replace_syscall(__NR_open,     virt_open);
	orig_readlink = replace_syscall(__NR_readlink, virt_readlink);
	orig_getcwd   = replace_syscall(__NR_getcwd,   virt_getcwd);

#if NEWVFS
	orig_stat64   = replace_syscall(__NR_stat64,   virt_stat64);
	orig_lstat64  = replace_syscall(__NR_lstat64,  virt_lstat64);
#endif

#ifdef __i386__
	orig_execve   = replace_syscall(__NR_execve,   virt_execve);
#endif

	return 0;
}

Example #3

File: trap-syscalls.c Project: ojno/trap-syscalls

static void instruction_cb(unsigned char *pos, unsigned len, void *arg)
{
	if (is_syscall_instr(pos, pos + len)) replace_syscall(pos, len);
}
