Silly Kernel Panic in Mac OS X 10.2.2

Posted by pudge on from the don't-try-this-at-home dept.

shibby tells us that it is easy to cause a kernel panic in Mac OS X 10.2.2, by attempting to move a directory into the same location as another one of the same name, using Terminal: mkdir ~/mydir; cd ~/mydir; mkdir mydir; mv mydir ... Kernel panic is instant. Save all your documents and quit your open apps if you feel the need to see it for yourself. Happy Thanksgiving!

    Be very careful with this - If you are testing, or accidentally gonna do this, you will lose both directories and all data in them.

    This was originally posted to the darwin-development mailing list, of which I'm a subscriber;

    Here's the message (login: archives, pass: archives)

    This list is teeming with Apple folks, so I'm sure someone's posted a RADAR bug already.

    This problem also came up on MacNN and is discussed in detail here

    Now here's the kicker - as the kernel is open-source (APSL - don't complain), someone's already traced the problem back to a recursive lock in the HFS+ subsystem (hfs_vnops.c). Kewl or wha'?

    Yep! The guys on MacNN posted feedback to Apple last week. Expect a kernel Software Update sometime soon, I guess.

  5. What's wrong with HFS+? by 2nd+Post! · · Score: 5, Informative

    What's missing that you want HFS+ to go away or something?

    It's got metadata, which Microsoft only *added* with NTFS
    It finally got journaling with 10.2.2
    It spans, quite comfortably, 180GB hard drives
    File sizes can be larger than 2gb, and I believe up to 2TB (2^63 bytes per file)

    Is there something missing? Perhaps encryption? Apple already has support for encrypted volumes...
