Subject: [PATCH] xen: Allow xenstored to map /proc/xen/xsd_kva
Date: Tue, 14 Jul 2020 14:20:07 +0100
Message-ID: <20200714132007.821541-1-anthony.perard@citrix.com> (raw)

xenstored is using mmap() on /proc/xen/xsd_kva, and when the SELinux
boolean "domain_can_mmap_files" in CentOS is set to false the mmap()
call fails.
