Subject: [patch v2 0/2] x86/dumpstack: Prevent access to foreign tasks user space
Date: Tue, 17 Nov 2020 21:23:33 +0100 [thread overview]
Message-ID: <20201117202333.869470686@linutronix.de> (raw)
This is the second version of the patch to prevent access to a foreign
tasks user space in copy_code(). It addresses the review comments from
Boris and adds a new patch which provides documentation for
copy_from_user_nmi() to avoid further confusion about it's usage.
V1 can be found here:

tglx
