Currently, pipe2 both closes the fds and releases references to the pipe vnode on failure. However, closing the fds already causes the vnode references to be dropped. Make pipe2 only release the vnode references when the respective file_t were not closed. Found by syzkaller fuzzing.

Running
If you built it from source, run make run-kvm or make run-disk-kvm
There are prebuilt images and instructions at https://astral-os.org/about.html.
Building
The build process dependencies are specified here. If you wish to use the make img option, you will need mtools. All other needed packages will be installed/built on a container.
It is highly recommended you download pre-built packages from the official repository by running make download. This greatly reduces the compilation time as it will only need to build the host tools.
To build the project, run make. This will create a file named astral.iso
After this, if you wish to create an ext2 disk image, run make disk
