From: "Daniel P. Berrange" <berrange(a)redhat.com&gt; Most versions of libselinux do not contain the function selinux_lxc_contexts_path() that the security driver recently started using for LXC. We must add a conditional check for it in configure and then disable the LXC security driver for builds where libselinux lacks this function. NB although this qualifies as a build breaker fix, I'm not pushing until it has had review * configure.ac: Check for selinux_lxc_contexts_path * src/security/security_selinux.c: Disable LXC security if selinux_lxc_contexts_path() is missing --- configure.ac | 1 + src/security/security_selinux.c | 19 ++++++++++++++++--- 2 files changed, 17 insertions(+), 3 deletions(-) diff --git a/configure.ac b/configure.ac index 9c356c9..d666736 100644 --- a/configure.ac +++ b/configure.ac @@ -1360,6 +1360,7 @@ else fail=0 AC_CHECK_FUNC([selinux_virtual_domain_context_path], [], [fail=1]) AC_CHECK_FUNC([selinux_virtual_image_context_path], [], [fail=1]) + AC_CHECK_FUNCS([selinux_lxc_contexts_path]) CFLAGS="$old_cflags" LIBS="$old_libs" diff --git a/src/security/security_selinux.c b/src/security/security_selinux.c index b0bb0a0..2b8ff19 100644 --- a/src/security/security_selinux.c +++ b/src/security/security_selinux.c @@ -127,6 +127,7 @@ err: } +#ifdef HAVE_SELINUX_LXC_CONTEXTS_PATH static int SELinuxLXCInitialize(virSecurityManagerPtr mgr) { @@ -189,6 +190,15 @@ error: VIR_FREE(data->content_context); return -1; } +#else +static int +SELinuxLXCInitialize(virSecurityManagerPtr mgr ATTRIBUTE_UNUSED) +{ + virReportSystemError(ENOSYS, "%s", + _("libselinux does not support LXC contexts path")); + return -1; +} +#endif static int @@ -443,9 +453,12 @@ SELinuxSecurityDriverProbe(const char *virtDriver) if (!is_selinux_enabled()) return SECURITY_DRIVER_DISABLE; - if (virtDriver && STREQ(virtDriver, "LXC") && - !virFileExists(selinux_lxc_contexts_path())) - return SECURITY_DRIVER_DISABLE; + if (virtDriver && STREQ(virtDriver, "LXC")) { +#if HAVE_SELINUX_LXC_CONTEXTS_PATH + if (!virFileExists(selinux_lxc_contexts_path())) +#endif + return SECURITY_DRIVER_DISABLE; + } return SECURITY_DRIVER_ENABLE; } -- 1.7.7.6
