The QEMU project is currently considering to move its bug tracking to another
system. For this we need to know which bugs are still valid and which could be
closed already. Thus we are setting older bugs to "Incomplete" now.
If you still think this bug report here is valid, then please switch the state
back to "New" within the next 60 days, otherwise this report will be marked as
"Expired". Or mark it as "Fix Released" if the problem has been solved with a
newer version of QEMU already. Thank you and sorry for the inconvenience.
** Changed in: qemu
Status: New => Incomplete

Title:
Listing the contents of / lists QEMU_LD_PREFIX instead
Status in QEMU:
Incomplete
Bug description:
Seeing this in qemu-user version 3.1.0
Demo:
$ QEMU_LD_PREFIX=$(pwd)/usr/armv7a-cros-linux-gnueabi ../run/qemu-arm
/tmp/coreutils --coreutils-prog=ls /
etc lib usr
$ ls /
boot etc lib lib64 lost+found mnt root sbin sys usr
bin dev export home lib32 net proc run tmp var
$ ls usr/armv7a-cros-linux-gnueabi
etc lib usr
In strace, the openat for "/" is remapped to the directory specified in
QEMU_LD_PREFIX:
[pid 5302] openat(AT_FDCWD, "/tmp/qemu/usr/armv7a-cros-linux-gnueabi",
O_RDONLY|O_NONBLOCK|O_DIRECTORY|O_CLOEXEC) = 3
As an aside, if I change the code to do chdir("/"); opendir("."); it
works fine.
