I don't know how many Android developers have a problem with the tragic performance of Android virtual machines, anyway, my opinion is: That's too much speed! Why are Android virtual machines much slower than iOS and WP7 's virtual machine? For the following reasons: 1. The Android simulator simulates the ARM architecture (Arm-eabi), while the target architecture for iOS and WP7 simulators is x86, and the App running in iOS emulator is compiled to

These days when you do MDT, you will always encounter x86\x64\ia64 these several folders. The first two are common, and are often encountered since the Win7 system appears. So I guess IA64 should also be some kind of architecture or version of the CPU. Now to the three made a summary. x86 or 80x86 is the general term of a microprocessor architecture that Intel first developed and manufactured. The older pro

code specified for the ASM segment. the ANSI C specification uses the keyword __asm__ to replace the keyword ASM when using inline assembly statements, because the ANSI C keyword ASM is used for other purposes. as follows: __asm__ ("Addl $, result\n\t" "Subl $, result\n\t");The Basic ASM format provides a simple style for creating assembly code, but there are some limitations. First, all input and output values must use the global variables of the C program, as seen in the example abo

same time, the PC completes the automatic addition of one operation, forming the address of the next operation instruction, that is, address No. 1th. Second instruction: With the first instruction, the PC sends the second instruction address to mar, commands the memory to do the reading operation, sends the 1th unit content to the MDR, also has the MDR sends to the IR, then the CU analyzes the operation code, if is the multiplication instruction, the CU sends the reading command to the memor

We can use conditional jump directives to create loops, but in fact there is a simpler series of loop instructions in assembly language. The loop instruction uses the ECX register as the cou

. The best use of the STOs directive is to work with the rep directive, copying a string value into a large string value several times, such as copying a space character to a 256-byte buffer area. The following example:# stos.s.section. DataSpace: . ASCII "". Section. BSS . Lcomm buffer, 256.section. Text.globl _start_start: NOP Leal Space,%esi Leal buffer,%edi movl $256,%ecx cld LODSB Rep STOSB Movl $,%eaxAfter make debug run as follows:Breakpoint 1, _start () at s

What is NX Bit? Its a exploit mitigation technique which makes certain areas of memory non executable and makes an executable area, non w Ritable. Example:data, stack and heap segments is made non executable while the text segment is made non writable. List the header information for an elf programReadelf-l Vuln How to bypass NX bit and achieve arbitrary code execution? NX bit can is bypassed using an attack technique called "return-to-libc". Here return address was overwrit

What are Off-by-one bugs? Copying source string to destination buffer could result in off-by-one when Source string length is equal to destination buffer length. When source string length was equal to destination buffer length, a single NULL byte gets copied just above the destination Buffer. Here since the destination buffer are located in stacks, the single NULL byte could overwrite the least significant bit (LSB ) of caller's EBP stored in the stacks and this could leads

differences between C and C + +// add _init segment in native code void _init (void) {}Note: _init is not a section, just an export function. The NDK generates the corresponding segment and merges it into a large section, so you can't see it from the Section table.Let's take a simple example of libhello.so as an example HELLO.C code as follows#include void_init (void) { }/** JNI Specifies that the local method name Java_ calls the package name of the local method class _ Class Name _ Method nam

In C, a union (union) is a bit like a struct, which organizes different types of data, but unlike structs, each member of a struct has its own memory space, and the total length of a struct object is the sum of the lengths of each member. In a union, each member shares a memory space, and the length of a Union object is equal to the longest length of each member.As described above, a consortium should have a multifaceted nature, that is, at the assembly level, it sometimes shows the structure's

generally have home,menu and back three standard buttons, if not, it is necessary to simulate:(1) When you press and hold the right side of the status bar, you will be prompted to open the status bar to simulate the function of the button: when open, click the status bar to indicate home, press the mouse button on the status bar and swipe from left to right to indicate menu, press the mouse button on the status bar and swipe right to left to indicate back. The same method also turns off the sta

Shell-storm here can have some shellcode that can be used, but their own writing is Biner Pride/Struggle0x00 does not write Shellcode (and what is the difference between a salted fish/cry) 0x01 There are two solutions to this problem.1. Shellcode direct access to the shell, this solution requires a strong shellcode writing ability, because only 27 bytes can be entered, requiring shellcode1 short enough2. First construct a read and then enlarge the read byte, then get the shell, so shellcode leng
