[PATCH for-7.1] applesmc: silence invalid key warning in case default one is used

[PATCH for-7.1] applesmc: silence invalid key warning in case default one is used

[Igor Mammedov]

QEMU probably can't carry OSK key[1] for legal reasons so it
can't supply the valid default key. However when tests are run
applesmc will pollute test log with distracting warning,
silence that warning so it won't distract maintainers/CI.

If user launches MacOS guest without supplying valid or any key
they will get upset MacOS (and legality of specifying valid key
on CLI is also questionable). This patch favors QEMU/tests vs
MacOS guest.

A patch from Apple needed to change default to the valid key,
until then prefer QEMU maintainers sanity/cleaner test logs
vs any inconvenience users running MacOS guest might suffer.

1) After some googling, it seems 'secret' key is the same for
   all Mac hardware and is widely known but whether it's
   permited to use that is up to lawyers/Apple to decide.

What test is causing this problem ?

This is a distinct bug fix from the problem described. We should
take this as a standalone fix no matter what.

This means users who invoke QEMU won't see the warning any more. This
feels like a dubious change, as it degrades the user experiance for
sake of tests - IMHO users takes priority over any testing.

The right fix is for bios-tables-tests to pass an explicit 'osk' value
then. As its a test it doesn't have to be a genuine OSK, jsut any old
64-byte string

We should either have a comment saying that this has to be exactly
64 characters and it doesn't matter what they are; or we could use
 any64characterfakeoskisenoughtopreventinvalidkeywarningsonstderr

that will work, care tho send a formal patch or should I take over?

However we still have bogus default_osk, yes it will cause warning which
typically nobody will see and end user will still end up with upset guest.
Right thing would be to require osk explicitly and drop default completely.
Users who actually run MacOS guest must be providing OSK explicitly already
so they won't be affected and anyone else using default is broken anyways
(whether QEMU started directly or through mgmt layer)

thought about it (until I started to write commit message for that)
but it becomes bug only if default_osk is treated as NULL terminated
string, which happens only if following hunk is applied.
Without that, it's treated as 64 bytes. (we can null-terminate it
anyways just to be on a safe side)

Could you spin something up, as I'm not in a position to do formal
testing today.

There are other patches onlist to make QEMU extract an osk from the
host hardware, which is ok because IIUC macOS allows you to run macOS
as a VM, provided the host is Apple hardware.

I applaud the renaissance of roman-style inscriptions, but it's not just
words without spaces, it's also capital letters only:

    ANY64CHARACTERFAKEOSKISENOUGHTOPREVENTINVALIDKEYWARNINGSONSTDERR

Seriously, throw in some dashes or spaces.
