[PATCH 0/3] Replace variable length arrays in ppc KVM code

Posted by Thomas Huth 9 months, 1 week ago

It would be good to enable -Wvla as an additional security feature
when compiling QEMU (see also Peter's explanation here:
https://lore.kernel.org/qemu-devel/20240125173211.1786196-1-peter.maydell@linaro.org/ ).
There are currently only two spots with variable lengths arrays left,
so if we fix those, we can finally enable the -Wvla compiler switch.

Peter Maydell (1):
  meson: Enable -Wvla

Thomas Huth (2):
  target/ppc/kvm: Replace variable length array in kvmppc_save_htab()
  target/ppc/kvm: Replace variable length array in kvmppc_read_hptes()
