Hello guys,
I own a very old Logitech diNovo media set with Keyboard, Mouse MX1000 for Bluetooth and Mediapad.
Since 4.19.41 I was able to use it without problem, but kernel 4.19.42 introduced two patches which one of them problably broke my Bluetooth setup support.
According to the changelog those might be:
commit 38f092c41cebaff589e88cc22686b289a6840559

Bluetooth: Align minimum encryption key size for LE and BR/EDR connections
commit d5bb334a8e171b262e48f378bd2096c0ea458265 upstream.
The minimum encryption key size for LE connections is 56 bits and to align LE with BR/EDR, enforce 56 bits of minimum encryption key size for BR/EDR connections as well.

Bluetooth: hidp: fix buffer overflow
commit a1616a5ac99ede5d605047a9012481ce7ff18b16 upstream.
Struct ca is copied from userspace. It is not checked whether the "name" field is NULL terminated, which allows local users to obtain potentially sensitive information from kernel stack memory, via a HIDPCONNADD command.
This vulnerability is similar to CVE-2011-1079.
My current working setup with 4.19.41 is as follows:

Can anybody please look at this and fix the support for my Bluetooth set so I do not need to throw it into dustbin?
Thank you in advance
