proposal: ifconfig list fails for unpriv user past 2c24ad3377a

[paepckehh]

Hello Team,
proposed fix for bugID:269042

Summary:
since 2c24ad3377a6f58 / D37873 ifconfig exits with permission denied when called by unpriviledged user and kldload(if_xxx) is called.

With this patch, it just behaves as before, no information is (silently) dropped or missing.

Greetings,
Michael

This patch would defeat the whole point, which is to catch the EPERM returned by kldload in a jail. What exactly is your problem? Could you please past the command you execute, the user you execute it as, and the expected result you'd like to see?

[paepckehh]

Sure,
my idea was to first restore as quick fix the expected behaviour for everyone else, because it can be hard to track down, to have some more time figure out the root cause behind the (pointless) kernel module access attempts

Why? Because not only lists is impacted, but also interface rename operations fail the same way. And, I do not even have kernel modules at all (zero). All interfaces are static within the main kernel and working otherwise (since years) rock stable that way.

Currently its <if_ue> that fails as soon I have more than one ue mapped nic. I will rollback the patch and add some more network interfaces and provide some traces.

Thank you!
Michael

Hello Alan,
if you have an idea why kldload is called at all ... ?
