On glibc-based systems, this header is +indirectly included via <limits.h>, <bits/posix1_lim.h>, +<bitts/local_lim.h>, but on other platforms this is not guaranteed due +to not being part of the POSIX standard. One examples are systems based +on musl libc, which do not include the <linux/limits.h> indirectly, +which leads to `XATTR_SIZE_MAX` being undefined. + +Fix this error by directly include <linux/limits.h>. As the 9P fs code +is being Linux-based either way, we can simply do so without breaking +other platforms. This enables building 9pfs on musl-based systems. + +Signed-off-by: Patrick Steinhardt <ps@pks.im> +[ Changes by AF + - Apply to the QEMU tree inside of Xen +] +Signed-off-by: Alistair Francis <alistair.francis@xilinx.com> +--- +Upstream Status: Pending review and acceptance + + tools/qemu-xen/hw/9pfs/9p.c | 1 + + 1 file changed, 1 insertion(+) + +diff --git a/tools/qemu-xen/hw/9pfs/9p.c b/tools/qemu-xen/hw/9pfs/9p.c +index 96d2683348..48cd558e96 100644 +--- a/tools/qemu-xen/hw/9pfs/9p.c ++++ b/tools/qemu-xen/hw/9pfs/9p.c +@@ -13,6 +13,7 @@ + + #include "qemu/osdep.h" + #include <glib/gprintf.h> ++#include <linux/limits.h> + #include "hw/virtio/virtio.h" + #include "qapi/error.h" + #include "qemu/error-report.h" +-- +2.13.2 |
