[zltl]

Environment

My Windows build number:

PS C:\Users\liaot> [Environment]::OSVersion

Platform ServicePack Version      VersionString
-------- ----------- -------      -------------
 Win32NT             10.0.18362.0 Microsoft Windows NT 10.0.18362.0

My Distribution version:
Ubuntu Release: 20.04

cat /proc/version:
Linux version 4.4.0-18362-Microsoft ([email protected]) (gcc version 5.4.0 (GCC) ) #836-Microsoft Mon May 05 16:04:00 PST 2020

Steps to reproduce

1. Download a centos6 rootfs from https://github.com/CentOS/sig-cloud-instance-images/tree/CentOS-6.10/docker

2. Extract it on wsl:

mkdir -p /fakeroot/c6
cp /path/to/centos-6-docker.tar.xz /fakeroot/c6
cd /fakeroot/c6
tar -xpf centos-6-docker.tar.xz  --numeric-owner
chroot /fakeroot/c6

Expected behavior

chroot to /fakeroot/c6

Actual behavior

Then I try centos7 rootfs and gentoo stage3, chroot work well both.

chroot to Centos6 rootfs work on real linux.

138   rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0
138   --- SIGSEGV {si_signo=SIGSEGV, si_code=SEGV_MAPERR, si_addr=0xffffffffff600400} ---

chroot to Centos6 rootfs work on real linux.

That depends on the disposition of the Real Linux in question about vsyscalls.
