[PATCH 0/2] KVM: Fix guest_memfd binding overlap errno and selftest

Posted by ZongYao.Chen@linux.alibaba.com 6 days, 22 hours ago

From: Zongyao Chen <ZongYao.Chen@linux.alibaba.com>

KVM rejects guest_memfd bindings that overlap an existing binding, but
currently reports -EINVAL from the generic error path.  Return -EEXIST for
binding conflicts and adjust the selftest so it actually reaches the
guest_memfd binding overlap check instead of failing earlier on GPA memslot
overlap.

Zongyao Chen (2):
  KVM: guest_memfd: Return -EEXIST for overlapping bindings
  KVM: selftests: Test guest_memfd binding overlap without GPA overlap
