Understanding the Memory Layout of Linux Executables

Required tools for playing around with memory:

hexdump
objdump
readelf
xxd
gcore

Edit /etc/mkinitcpio.conf as root

MODULES=(kvmgt vfio vfio-iommu-type1 vfio-mdev)

sudo mkinitcpio --allpresets

Edit /etc/default/grub as root

If you cannot install Intel VTune Amplifier on Manjaro/Arch Linux (or other non-supported OS), because this shit cannot find installed libraries via ldconfig -p, you can use this script.
Unpack vtune_amplifier_2019_update3.tar.gz, then go to vtune_amplifier_2019_update3, then copy and paste following:

shopt -s globstar

for i in **/sysreq.cab; do
    echo "processing ${i}"
    perl -pi -e 's/(\W*)RESULT=255(.*)/\1RESULT=1  \2/' "${i}"  # COMPARE_VERSIONS() never returns 255
    perl -pi -e 's/(\W*)LI_(.+)=unsupp(.*)/\1LI_\2=ok    \3/' "${i}"

x11vnc over passwordless SSH with Google Authenticator on Arch Linux

How auth will look after configuration:

Enter your private key password: 
User: user
< client sends his public key to server, signed by client's private key (correct me if I am wrong) >
2FA code: 123123
user's password:
