[PATCH 0/2] tracing/user_events: harden dynamic field validation

[Yifan Zhang]

Harden two user-event field validation boundaries found with KASAN.  The
first patch enforces the minimum storage required for a dynamic cpumask.
The second rejects field layouts whose accumulated offsets overflow or no
longer fit the signed fields used downstream.

Yifan Zhang (2):
  tracing/user_events: validate dynamic cpumask size
  tracing/user_events: reject overflowing field offsets
