Hi List!
I built UML from 2.6.10 sources with no additional uml-specific patches.
My Host is also 2.6.10 with skas. I discovered that when (my) uml is running
as root _every_ user-id inside the uml may chmod _every_ file on a hostfs mount
and therfore become root etc...
This also happens if the hostfs mount is not the root-fs.
Is the following behaviour desired? If not: what could cause it?
[EMAIL PROTECTED]:~$ grep root /proc/mounts
rootfs / rootfs rw 0 0
/dev/root / hostfs rw 0 0
[EMAIL PROTECTED]:~$ id
uid=1000(xraz) gid=104(xraz) groups=104(xraz),9997(chefs)
[EMAIL PROTECTED]:~$ ls -la /bin/dash
- -rwxr-xr-x 1 root root 83960 Aug 22 20:28 /bin/dash
[EMAIL PROTECTED]:~$ chmod 4755 /bin/dash
[EMAIL PROTECTED]:~$ ls -la /bin/dash
- -rwsr-xr-x 1 root root 83960 Aug 22 20:28 /bin/dash
[EMAIL PROTECTED]:~$ /bin/dash -c id
uid=1000(xraz) gid=104(xraz) euid=0(root) groups=104(xraz),9997(chefs)
What is going wrong?
Because i suppose this is a local error and not an uml-bug i don't yet include
debuginfo about my uml & system here.
