On glibc-based systems, this header is 9indirectly included via <limits.h>, <bits/posix1_lim.h>, 10<bitts/local_lim.h>, but on other platforms this is not guaranteed due 11to not being part of the POSIX standard. One examples are systems based 12on musl libc, which do not include the <linux/limits.h> indirectly, 13which leads to `XATTR_SIZE_MAX` being undefined. 14 15Fix this error by directly include <linux/limits.h>. As the 9P fs code 16is being Linux-based either way, we can simply do so without breaking 17other platforms. This enables building 9pfs on musl-based systems. 18 19Signed-off-by: Patrick Steinhardt <ps@pks.im> 20[ Changes by AF 21 - Apply to the QEMU tree inside of Xen 22] 23Signed-off-by: Alistair Francis <alistair.francis@xilinx.com> 24--- 25Upstream Status: Pending review and acceptance 26 27 tools/qemu-xen/hw/9pfs/9p.c | 1 + 28 1 file changed, 1 insertion(+) 29 30diff --git a/tools/qemu-xen/hw/9pfs/9p.c b/tools/qemu-xen/hw/9pfs/9p.c 31index 96d2683348..48cd558e96 100644 32--- a/tools/qemu-xen/hw/9pfs/9p.c 33+++ b/tools/qemu-xen/hw/9pfs/9p.c 34@@ -13,6 +13,7 @@ 35 36 #include "qemu/osdep.h" 37 #include <glib/gprintf.h> 38+#include <linux/limits.h> 39 #include "hw/virtio/virtio.h" 40 #include "qapi/error.h" 41 #include "qemu/error-report.h" 42-- 432.13.2 44
