5.15.17: general protection fault when loading iwlwifi as module and no firmware available
Hello,
we found a regression in 5.15.17. When iwlwifi is loaded as a module and it cannot load a firmware it crashes:

Can you do 'git bisect' to track down the offending commit?
And does 5.16.y work for you? How about 5.17-rc2?
thanks,

e23f075d77987de4215c8e0696f28bcc707506f7 is the first bad commit commit e23f075d77987de4215c8e0696f28bcc707506f7 Author: Johannes Berg johannes.berg@intel.com Date: Fri Dec 10 11:12:42 2021 +0200
iwlwifi: fix leaks/bad data after failed firmware load
[ Upstream commit ab07506b0454bea606095951e19e72c282bfbb42 ]
If firmware load fails after having loaded some parts of the firmware, e.g. the IML image, then this would leak. For the host command list we'd end up running into a WARN on the next attempt to load another firmware image.
Fix this by calling iwl_dealloc_ucode() on failures, and make that also clear the data so we start fresh on the next round.

I reverted this patch (and also the following one, 58d53fe49a5dfbd9204c6d605bff4c99f7549256, so the blamed patch reverted cleanly) in 5.15.17. The general protection fault then disappeared.
I did not hat time yet to test 5.16 or 5.17-rc2.

Providing a firmware file (or blacklisting iwlwifi of course) fixes ist. 5.15.16 does not crash.
Can you do 'git bisect' to track down the offending commit?
And does 5.16.y work for you? How about 5.17-rc2?
thanks,
greg k-h
I tested 5.17-rc2. It also shows the above general protection fault:
Great! Please contact the authors of the commit you found, and the wireless developer mailing list and they can work to resolve this.
