memfd patch not applied during pip installation from git

[SpaceMoehre]

I'm trying to setup the shellphuzz but it appears as the pip installation does not apply the memfd patch necessary for afl qemu mode. My Dockerfile:

FROM ubuntu:18.04

RUN cp /etc/apt/sources.list /etc/apt/sources.list~
RUN sed -Ei 's/^# deb-src /deb-src /' /etc/apt/sources.list
RUN apt-get update && apt-get install build-essential gcc-multilib debootstrap debian-archive-keyring libtool-bin bison python3 virtualenv git python3-dev automake -y
RUN apt-get build-dep qemu -y

RUN virtualenv -ppython3 /opt/venv
RUN /opt/venv/bin/pip install git+https://github.com/shellphish/driller

RUN /opt/venv/bin/pip install git+https://github.com/shellphish/shellphish-afl
RUN /opt/venv/bin/pip install git+https://github.com/shellphish/fuzzer

It runs without problems until it tries to execute afl's build_qemu_support.sh script:

  ----------------------------------------
  ERROR: Failed building wheel for shellphish-afl

The error code originates from the missing memfd patch. Even though the memfd.diff is included in this repo, it looks like its not patched:

  [+] Cryptographic signature on qemu-2.10.0.tar.xz checks out.
  [*] Uncompressing archive (this will take a while)...
  [+] Unpacking successful.
  [*] Configuring QEMU for ...
  [*] Applying patches...
  patching file linux-user/elfload.c
  patching file accel/tcg/cpu-exec.c
  patching file linux-user/syscall.c
  [+] Patching done.

EDIT:

when i normally build qemu support the patching looks more like this:

[*] Applying patches...
patching file linux-user/elfload.c
patching file accel/tcg/cpu-exec.c
patching file linux-user/syscall.c
patching file configure
Hunk #1 succeeded at 3855 (offset -68 lines).

I was facing the same problem. After installing lsb-release in the docker, the qemu scripts will apply the patch successfully.

[SpaceMoehre]

actually fixes it

I have the same problem: memfd patch isn't applied. Attempting to install it in WSL 2 Ubuntu 22.04, with Python 3 virtual env
