unable to read symlinks when mounting 9p filesystem with security_model=mapped
I am trying to use clang that is mounted from a 9p filesystem that has the options
-fsdev local,id=virtfs3,path=/clang,security_model=mapped-file -device virtio-9p-pci,fsdev=virtfs3,mount_tag=clang
clang has symlinks to clang-9. eg /clang/clang/bin/clang is a symlink that points to clang-9 in the current directory.
the clang filesystem is on a bind mount point on /clang/clang on the host and this is mapped to the same place on the guest. If I have the same virtfs mount point with the security_model=none I don't have this problem.
On the host: readlink clang
clang-9
and guest:
ls: cannot read symbolic link 'clang': No such file or directory
lrwxrwxrwx 1 root root 7 May 30 02:21 clang
readlink clang
returns nothing.
This is an automated cleanup. This bug report has been moved to QEMU's
new bug tracker on gitlab.com and thus gets marked as 'expired' now.
