From cff7ec6ee4af587761cae0819471cb28d48463d8 Mon Sep 17 00:00:00 2001 From: Phil Sutter Date: Tue, 4 Apr 2017 16:26:50 +0200 Subject: [PATCH] tc: m_xt: Fix segfault with iptables-1.6.0 Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1326726 Upstream Status: iproute2.git commit 97a02cabefb2e commit 97a02cabefb2e2dcfe27f89943709afa84be5525 Author: Phil Sutter Date: Thu Jan 12 15:22:49 2017 +0100 tc: m_xt: Fix segfault with iptables-1.6.0 Said iptables version introduced struct xtables_globals field 'compat_rev', a function pointer. Initializing it is mandatory as libxtables calls it without existence check. Without this, tc segfaults when using the xt action like so: | tc filter add dev d0 parent ffff: u32 match u32 0 0 \ | action xt -j MARK --set-mark 20 Signed-off-by: Phil Sutter --- tc/m_xt.c | 3 +++ 1 file changed, 3 insertions(+) diff --git a/tc/m_xt.c b/tc/m_xt.c index 8317f31..890dddd 100644 --- a/tc/m_xt.c +++ b/tc/m_xt.c @@ -77,6 +77,9 @@ static struct xtables_globals tcipt_globals = { .orig_opts = original_opts, .opts = original_opts, .exit_err = NULL, +#if (XTABLES_VERSION_CODE >= 11) + .compat_rev = xtables_compatible_revision, +#endif }; /* -- 1.8.3.1
