Re: [Xen-devel] [PATCH 0/6] grub-xen: support booting huge pv-domains
Ping? On 11/02/2015 06:51 AM, Juergen Gross wrote: The Xen hypervisor supports starting a dom0 with large memory (up to the TB range) by not including the initrd and p2m list in the initial kernel mapping.

I got the same error when compiling Xen (commit 6f04de6) by gcc 4.8.4 on Ubuntu 14.04.3. And adding "(void)" ahead of fgets() in the existing code cannot eliminate the error/warning message.

Introduce a separate X86_PTDUMP_CORE config that enables the code for dumping the page tables without enabling the debugfs interface, so that DEBUG_WX can be enabled without exposing the debugfs interface. Switch EFI_PGT_DUMP to using X86_PTDUMP_CORE so that it also does not require enabling the debugfs interface. On success it prints this to the kernel log: x86/mm: Checked W+X mappings: passed, no W+X pages found.

Re: [Xen-devel] Critique of the Xen Security Process
Well exposed, thank you Johanna. Just one question: anybody knows which EAL level has Xen being certified for? The question may seem stupid, but I wonder if the approach of closing execution path can survive to semiformal or formal verification.

This is scary, but unfortunately, it's commonplace. There is a sad
mentality of not including basic checks because it will generate extra
instructions that will take more microseconds to execute. That may have
been a concern when we were running 1MHz 8-bit processors, but now that
code takes such an insignificant amount of time to execute that it doesn't
matter. Coding should no longer be about making it as fast and efficient
as possible -- it needs to be about making it stable and secure.
