\section{Dashboard memory watch}
|
||||
Dashboard GDB pozwala na dynamiczne obserwowanie określonych obszarów pamięci. Używając funkcji \texttt{dashboard memory watch}, można ustawić obserwację na konkretne adresy pamięci.
|
||||
|
||||
\begin{lstlisting}[language=bash]
|
||||
dashboard memory watch 0x1ff80 128
|
||||
\end{lstlisting}
|
||||
|
||||
\noindent
|
||||
Powyższa komenda skonfiguruje dashboard do obserwacji 128 bajtów pamięci, począwszy od adresu \texttt{0x1ff80}.
|
||||
|
||||
\section{Obserwacja pamięci przy użyciu watch w GDB}
|
||||
Aby obserwować pamięć na niskim poziomie w GDB, można użyć komendy \texttt{watch} w połączeniu z rzutowaniem i rozmiarem obserwowanego obszaru. Przykładowo, aby obserwować 128 bajty pamięci zaczynając od adresu \texttt{0x1ff80}, użyjemy następującej komendy:
|
||||
|
||||
\begin{lstlisting}[language=bash]
|
||||
watch *(char*)0x1ff80 @ 128
|
||||
\end{lstlisting}
|
||||
|
||||
Ta komenda spowoduje przerwanie wykonania programu, gdy wartości w obserwowanym obszarze pamięci ulegną zmianie. Użycie rzutowania na typ \texttt{(char*)} pozwala na interpretację adresu jako wskaźnika na bajty, a operator \texttt{@} określa ilość obserwowanych bajtów.
|
||||
|
||||
\section{Clear Memory}
|
||||
|
||||
\subsection{Basic Usage}
|
||||
To clear 128 bytes of memory starting from 0x1FF80, use the following script:
|
||||
|
||||
\begin{lstlisting}[language=bash]
|
||||
#./gdb/zero.py
|
||||
|
||||
import gdb
|
||||
for i in range(0, 128): # 128 bajtów
|
||||
gdb.execute("set *((char*)0x1FF80 + %d) = 0" % i)
|
||||
\end{lstlisting}
|
||||
|
||||
Run this script from GDB dashboard by:
|
||||
|
||||
\begin{lstlisting}[language=bash]
|
||||
source gdb/zero.py
|
||||
\end{lstlisting}
|
||||
|
||||
\subsection{Option 2: With Parameters}
|
||||
To dynamically set the starting address, number of bytes, and pattern from the command line, modify the script as follows:
|
||||
|
||||
\begin{lstlisting}[language=bash]
|
||||
#./gdb/zero_with_params.py
|
||||
|
||||
import gdb
|
||||
import sys
|
||||
|
||||
# Parse arguments from the GDB command
|
||||
args = gdb.string_to_argv(gdb.parameter("args"))
|
||||
if len(args) != 3:
|
||||
print("Usage: source gdb/zero_with_params.py <start_address> <num_bytes> <pattern>")
|
||||
else:
|
||||
start_address = int(args[0], 16) # Convert start address from hex to int
|
||||
num_bytes = int(args[1], 16) # Convert number of bytes from hex to int
|
||||
pattern = int(args[2], 16) # Convert pattern from hex to int
|
||||
|
||||
for i in range(num_bytes):
|
||||
gdb.execute("set *((char*)%d + %d) = %d" % (start_address, i, pattern))
|
||||
\end{lstlisting}
|
||||
|
||||
To run this script with parameters, set GDB's `args` parameter before sourcing the script:
|
||||
|
||||
\begin{lstlisting}[language=bash]
|
||||
set args 0x1FF80 0x80 0x30
|
||||
source gdb/zero_with_params.py
|
||||
\end{lstlisting}
|
||||
|
||||
This allows specifying the starting address, number of bytes to clear, and the pattern to use directly from the GDB command line.
