Re: Latest Git kernel: avahi-daemon[2410]: ioctl(): Inappropriate ioctl for device

Kernel 5.5 PowerPC is also affected.

I don't know what you mean by that. What sha are you talking about?

I have a system with avahi running and everything's fine.

The key question is what ioctl is it complaining about. You should be
able to find that via strace.

Hi All,

The issue with the avahi-daemon still exist in the latest Git kernel. It's a PowerPC issue. I compiled the latest Git kernel on a PC today and there aren't any issues with the avahi daemon. Another Power Mac user reported the same issue on his G5. I tested with the AmigaOne X1000 and X5000 in the last days.

I bisected today but I think the result isn't correct because it found the other problem with ordering of PCSCSI definition in esp_rev enum. I don't know how to bisect if there is another issue at the same time. Maybe "git bisect skip"?

    scsi: esp_scsi: Correct ordering of PCSCSI definition in esp_rev enum

    The order of the definitions in the esp_rev enum is important. The values
    are used in comparisons for chip features.

    Add a comment to the enum explaining this.

    Also, the actual values for the enum fields are irrelevant, so remove the
    explicit values (suggested by Geert Uytterhoeven). This makes adding a new
    field in the middle of the enum easier.

    Finally, move the PCSCSI definition to the right place in the enum. In its
    previous location, at the end of the enum, the wrong values are written to
    the CONFIG3 register when used with FAST-SCSI targets.
