[Qemu-devel] seccomp breakage on arm

["Andreas Färber" <afaerber@suse.de>]

Hello,

I am seeing the following build failure on openSUSE Tumbleweed armv7l
with --enable-seccomp in v2.3.0-rc2:

[  551s] In file included from qemu-seccomp.c:16:0:
[  551s] /usr/include/libseccomp/seccomp.h:177:23: error: '__NR_mmap'

[  551s]  #define SCMP_SYS(x)  (__NR_##x)

Is this a problem with libseccomp 2.2.0 / master and needs to be fixed
in the library? Or do we need to #ifdef some syscalls in qemu-seccomp.c?

aarch64 builds fine. For ppc and ppc64 we're carrying a libseccomp patch
in openSUSE, those build okay then; ppc64le is still missing in libseccomp.

Regards,
Andreas
