From mboxrd@z Thu Jan 1 00:00:00 1970 From: Peter Korsgaard Date: Sun, 19 Jan 2020 18:03:56 +0100 Subject: [Buildroot] [PATCH 1/3] package/xen: explicitly disable checkpolicy logic Message-ID: <20200119170358.5408-1-peter@korsgaard.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: buildroot@busybox.net Fixes: http://autobuild.buildroot.net/results/14af2dc3219847a92c6ec2db14ba387159b61fde The Xen build system builds and embeds a default XSM FLASK (Flux Advanced Security Kernel) security policy if it detects SELinux checkpolicy on the build machine. If enabled, a gen-policy.py python script is used to convert the binary FLASK policy to a C array initialization list to embed it in the Xen binary. Depending on the python version and locale available on the host, this fails with byte values outside the 0..255 range: policy.c:7:10: error: unsigned conversion from 'int' to 'unsigned char' changes value from '56575' to '255' [-Werror=overflow] 0xdc8c, 0xdcff, 0x7c, 0xdcf9, 0x08, 0x00, 0x00, 0x00, 0x58, 0x65, 0x6e, 0x46, 0x6c, To fix this and ensure a consistent build, pass XEN_HAS_CHECKPOLICY=n to disable the checkpolicy detection.
