From d4897acff85b6c5e06f084cacffd4a5faf5a43e0 Mon Sep 17 00:00:00 2001 From: Stefan Berger Date: Tue, 16 Nov 2010 21:18:21 -0500 Subject: [PATCH] nwfilter: also purge ip(6)tables rules before detecting IP address Rather than only cleaning any remaining ebtables rules, also clean those applied to iptables and ip6tables when detecting the IP address of an interface. Previous applied iptables rules may hinder DHCP packets. --- src/nwfilter/nwfilter_ebiptables_driver.c | 7 ++++--- 1 file changed, 4 insertions(+), 3 deletions(-) diff --git a/src/nwfilter/nwfilter_ebiptables_driver.c b/src/nwfilter/nwfilter_ebiptables_driver.c index 7b2a50509b..9b7a7c8b07 100644 --- a/src/nwfilter/nwfilter_ebiptables_driver.c +++ b/src/nwfilter/nwfilter_ebiptables_driver.c @@ -117,6 +117,7 @@ static int ebtablesRemoveBasicRules(const char *ifname); static int ebiptablesDriverInit(void); static void ebiptablesDriverShutdown(void); static int ebtablesCleanAll(const char *ifname); +static int ebiptablesAllTeardown(const char *ifname); static virMutex execCLIMutex; @@ -2942,7 +2943,7 @@ ebtablesApplyBasicRules(const char *ifname, virFormatMacAddr(macaddr, macaddr_str); - ebtablesCleanAll(ifname); + ebiptablesAllTeardown(ifname); ebtablesCreateTmpRootChain(&buf, 1, ifname, 1); @@ -3041,7 +3042,7 @@ ebtablesApplyDHCPOnlyRules(const char *ifname, virFormatMacAddr(macaddr, macaddr_str); - ebtablesCleanAll(ifname); + ebiptablesAllTeardown(ifname); ebtablesCreateTmpRootChain(&buf, 1, ifname, 1); ebtablesCreateTmpRootChain(&buf, 0, ifname, 1); @@ -3143,7 +3144,7 @@ ebtablesApplyDropAllRules(const char *ifname) return 1; } - ebtablesCleanAll(ifname); + ebiptablesAllTeardown(ifname); ebtablesCreateTmpRootChain(&buf, 1, ifname, 1); ebtablesCreateTmpRootChain(&buf, 0, ifname, 1); -- GitLab
