Attach to a running process with
gdb -x trace-dyn-mem -p $PID
After every malloc the returned value (the allocated address) will be read from the RAX (64 bits) register.
After every free the last item in the backtrace (the free itself) will be shown. With the libc6-dbg package installed you can see the address passed as the first argument of free.
| 8.2.3. HTTP log format | |
| ---------------------- | |
| The HTTP format is the most complete and the best suited for HTTP proxies. It | |
| is enabled by when "option httplog" is specified in the frontend. It provides | |
| the same level of information as the TCP format with additional features which | |
| are specific to the HTTP protocol. Just like the TCP format, the log is usually | |
| emitted at the end of the session, unless "option logasap" is specified, which | |
| generally only makes sense for download sites. A session which matches the | |
| "monitor" rules will never logged. It is also possible not to log sessions for |
| all: fakeioctl.so | |
| CFLAGS=-D_GNU_SOURCE -g -Wall | |
| fakeioctl.so: fakeioctl.c | |
| gcc $(CFLAGS) -fPIC -shared -ldl -o fakeioctl.so fakeioctl.c | |
