Subject: [PATCH v5.5 17/30] KVM: s390: Skip gfn/size sanity checks on memslot DELETE or FLAGS_ONLY
Date: Thu, 4 Nov 2021 00:25:18 +0000 [thread overview]
Message-ID: <20211104002531.1176691-18-seanjc@google.com> (raw)
In-Reply-To: <20211104002531.1176691-1-seanjc@google.com>
Sanity check the hva, gfn, and size of a userspace memory region only if
any of those properties can change, i.e. skip the checks for DELETE and
FLAGS_ONLY. KVM doesn't allow moving the hva or changing the size, a gfn
change shows up as a MOVE even if flags are being modified, and the
checks are pointless for the DELETE case as userspace_addr and gfn_base
are zeroed by common KVM.
No functional change intended.
