Description

9 years ago
I noticed that my new Mac VMs running on Parallels are regularly losing suid permissions on many files, including su and sudo, which is very unhelpful.

I now sepnt some time looking on Google to find what could be the issue, and found that others have seen this with 10.5.6 VMs on Parallels as well, as well as a host-side setting that should prevent this (yay!) - now I just need someone to apply that.

See http://forum.parallels.com/showpost.php?s=ab46412fbba9980a6760e3a490cb00b3&p=369469&postcount=48 for what setting is needed on more recent Parallels versions and http://forum.parallels.com/showpost.php?s=ab46412fbba9980a6760e3a490cb00b3&p=370767&postcount=57 for what older ones need (not sure which build we have there).

Just as a reminder for me or anyone else who will see such permissions failures on Mac OS X VMs in the future, the problems can be repaired from a login via ssh (as root) by running the following command:

diskutil repairPermissions /

Ideally, this should be done/repeated once that setting on the host is made correctly, as opening any suid program and then running memory-intense stuff (compiling Mozilla, anyone?) tends to re-set permissions and lose suid due to the bug which is prevented by that flag.

I emailed you offline but I have a hot fix from Parallels that's supposed to address some bug fixes and is newer than the one mentioned in the second link.  To add that CPU flag, the OSX VMs need to be powered off anyways.

When's a good time to take a downtime to upgrade Parallels and add the flags?

Yay, that sounds really good, I'm looking forward to that!

I'll make sure to shut down all the VMs tomorrow, they are testing-only for now in any case.
