Instructions

Building the docker image

Clone the repo and build the docker image:

git clone https://github.com/irgstg/mte-docker-image.git

cd mte-docker-image

sudo docker build -t mte_image .

Running the container

Running the container:

sudo docker run -it mte_image /bin/bash

When inside the container, you can run QEMU:

qemu-system-aarch64 -machine virt,mte=on -cpu max -kernel $KIMAGE -hda $FSIMAGE -m 2G -display none -serial stdio -append "root=/dev/vda"

Run the sample executable

Run the sample executable, generated from resources/main.c:

GLIBC_TUNABLES=glibc.mem.tagging=1 /exe_name

SIGSEGV should be on it's way...

Debugging with gdbserver (on host) - optional

buildroot generates cross debugger, which can be attached via gdbserver.

Run qemu in the background, forwards two ports:

qemu-system-aarch64 -machine virt,mte=on -cpu max -kernel $KIMAGE -hda $FSIMAGE -m 2G -display none -serial stdio -append "root=/dev/vda" -net user,hostfwd=tcp::2000-:2000,hostfwd=tcp::10023-:22 -net nic </dev/null &>/dev/null &

run gdbserver via ssh:

ssh -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no -o IdentitiesOnly=yes -p 10023 root@localhost gdbserver localhost:2000 /exe_name </dev/null &>/dev/null &

Run hosts gdb:

$WORKDIR/buildroot/output/host/bin/aarch64-buildroot-linux-gnu-gdb $RSC_DIR/exe_name

Attach to guests gdbserver:

target remote localhost:2000
