Auto dump mode always starts from zero

[WcLyic]

Auto mode has its own variables (start_addr, end_addr), but these variables are just used in calculating seg_size.

MemDumper/jni/kmods.cpp

Lines 273 to 285 in 8368b58

 //Segment Start Address 
 kaddr start_addr = get_module_base(name.c_str()); 
 if (start_addr == 0) { 
     cout << "Can't find Segment: " << name.c_str() << endl; 
     return -1; 
 } 
  
 //Segment End Address 
 kaddr end_addr = get_module_end(name.c_str()); 
 if (end_addr == 0) { 
     cout << "Can't find End of Segment: " << name.c_str() << endl; 
     return -1; 
 } 

Then dumping always starts from startAddr which is always zero in auto mode.

Lines 296 to 308 in 8368b58

 if (isFastDump) { 
     uint8_t *buffer = new uint8_t[seg_size]; 
     memset(buffer, '\0', seg_size); 
     vm_readv((void *) startAddr, buffer, seg_size); 
     sdump.write((char *) buffer, seg_size); 
 } else { 
     char *buffer = new char[1]; 
     while (seg_size != 0) { 
         vm_readv((void *) (startAddr++), buffer, 1); 
         sdump.write(buffer, 1); 
         --seg_size; 
     } 
 }
