From: Marc-André Lureau <marcandre.lureau@redhat.com>

With qemu <= 3.0, when using "-seccomp on", the seccomp policy is only
applied to the main thread, the vcpu worker thread and other worker
threads created after seccomp policy is applied; the seccomp policy is
not applied to e.g. the RCU thread because it is created before the
seccomp policy is applied.

Since qemu commit 70dfabeaa79ba4d7a3b699abe1a047c8012db114 "seccomp:
set the seccomp filter to all threads", qemu will require seccomp
TSYNC flag, and will fail to start if the flag isn't available.

Without it, sandboxing is flawed. Disable seccomp capability if the
host is not capable of using seccomp TSYNC.

This all looks fine, but it will trigger a latent bug in virQEMUCapsIsValid.

It only checks kernelVersion for match for the -accel kvm case. We need
to check kernelVersion unconditionally for all emulators we cache.

Is there a reason for qemu to advertise 'sandbox' in
query-commandline-options if it's not usable?

Copying the QEMU logic in libvirt does not seem sustainable.

I suppose qemu could probe for the host support, and remove the
-sandbox option if host is not capable.

The problem would remain for older versions of qemu though.

So maybe a better plan is to:
- remove sandbox capability if qemu <  3.1
- disable -sandbox in qemu if host doesn't support TSYNC

What do you think?

If we do the check for qemu < 3.1, then libvirt breaks if a distro
backports the fix (eg to RHEL-7).

If we don't check for qemu < 3.1, then we used -sandbox, but it has
no benefit because its trivially escaped from other threads. This is
no worse than how it has worked for entire of existance of the -sandbox
command.

So probably on balance it sufficient to just make QEMU hide -sandbox
if TSYNC is missing, and ignore the question of old QEMUs.

Daniel

You may need to use the following Makefile variables when linking.
Use them in <program>_LDADD when linking a program, or
in <library>_a_LDFLAGS or <library>_la_LDFLAGS when linking a library.
  $(GETADDRINFO_LIB)
  $(GETHOSTNAME_LIB)
  $(HOSTENT_LIB)
  $(INET_NTOP_LIB)
  $(INET_PTON_LIB)
  $(LDEXP_LIBM)
  $(LIBSOCKET)
  $(LIB_CLOCK_GETTIME)
  $(LIB_EXECINFO)
  $(LIB_FDATASYNC)
  $(LIB_POLL)
  $(LIB_PTHREAD)
  $(LIB_PTHREAD_SIGMASK)
  $(LIB_SELECT)
  $(LTLIBINTL) when linking with libtool, $(LIBINTL) otherwise
  $(LTLIBTHREAD) when linking with libtool, $(LIBTHREAD) otherwise
  $(PTY_LIB)
  $(SERVENT_LIB)

Don't forget to
  - "include gnulib.mk" from within "gnulib/lib/Makefile.am",
  - "include gnulib.mk" from within "gnulib/tests/Makefile.am",
  - mention "-I m4" in ACLOCAL_AMFLAGS in Makefile.am,
  - mention "m4/gnulib-cache.m4" in EXTRA_DIST in Makefile.am,
  - invoke gl_EARLY in ./configure.ac, right after AC_PROG_CC,
  - invoke gl_INIT in ./configure.ac.
