2012-03-06bridge: netfilter: don't call iptables on vlan packets if sysctl is offFlorian Westphal
When net.bridge.bridge-nf-filter-vlan-tagged is 0 (default), vlan packets arriving should not be sent to ip(6)tables by bridge netfilter. However, it turns out that we currently always send VLAN packets to netfilter, if .. a), CONFIG_VLAN_8021Q is enabled ; or b), CONFIG_VLAN_8021Q is not set but rx vlan offload is enabled on the bridge port. This is because bridge netfilter treats skb with skb->protocol == ETH_P_IP{V6} as "non-vlan packet". With rx vlan offload on or CONFIG_VLAN_8021Q=y, the vlan header has already been removed here, and we cannot rely on skb->protocol alone. Fix this by only using skb->protocol if the skb has no vlan tag, or if a vlan tag is present and filter-vlan-tagged bridge netfilter sysctl is enabled. We cannot remove the skb->protocol == htons(ETH_P_8021Q) test because the vlan tag is still around in the CONFIG_VLAN_8021Q=n && "ethtool -K $itf rxvlan off" case. reproducer: iptables -t raw -I PREROUTING -i br0 iptables -t raw -I PREROUTING -i br0.1 Then send packets to an ip address configured on br0.1 interface. Even with net.bridge.bridge-nf-filter-vlan-tagged=0, the 1st rule will match instead of the 2nd one. With this patch applied, the 2nd rule will match instead. In the non-local address case, netfilter won't be consulted after this patch unless the sysctl is switched on.

2011-12-01bridge: master device stuck in no-carrier state forever when in user-stp modeVitalii Demianets
When in user-stp mode, bridge master do not follow state of its slaves, so after the following sequence of events it can stuck forever in no-carrier state: 1) turn stp off 2) put all slaves down - master device will follow their state and also go in no-carrier state 3) turn stp on with bridge-stp script returning 0 (go to the user-stp mode) Now bridge master won't follow slaves' state and will never reach running state. This patch solves the problem by making user-stp and kernel-stp behavior similar regarding master following slaves' states.

2011-10-06bridge: allow forwarding some link local framesstephen hemminger
This is based on an earlier patch by Nick Carter with comments by David Lamparter but with some refinements. Thanks for their patience this is a confusing area with overlap of standards, user requirements, and compatibility with earlier releases. It adds a new sysfs attribute /sys/class/net/brX/bridge/group_fwd_mask that controls forwarding of frames with address of: 01-80-C2-00-00-0X The default setting has no forwarding to retain compatibility. One change from earlier releases is that forwarding of group addresses is not dependent on STP being enabled or disabled. This choice was made based on interpretation of tie 802.1 standards. I expect complaints will arise because of this, but better to follow the standard than continue acting incorrectly by default. The filtering mask is writeable, but only values that don't forward known control frames are allowed. It intentionally blocks attempts to filter control protocols. For example: writing a 8 allows forwarding 802.1X PAE addresses which is the most common request.

2011-09-15net: consolidate and fix ethtool_ops->get_settings callingJiri Pirko
This patch does several things: - introduces __ethtool_get_settings which is called from ethtool code and from drivers as well. Put ASSERT_RTNL there. - dev_ethtool_get_settings() is replaced by __ethtool_get_settings() - changes calling in drivers so rtnl locking is respected. In iboe_get_rate was previously ->get_settings() called unlocked. This fixes it. Also prb_calc_retire_blk_tmo() in af_packet.c had the same problem. Also fixed by calling __dev_get_by_index() instead of dev_get_by_index() and holding rtnl_lock for both calls. - introduces rtnl_lock in bnx2fc_vport_create() and fcoe_vport_create() so bnx2fc_if_create() and fcoe_if_create() are called locked as they are from other places. - use __ethtool_get_settings() in bonding code Signed-off-by: Jiri Pirko <jpirko@redhat.com> v2->v3: -removed dev_ethtool_get_settings() -added ASSERT_RTNL into __ethtool_get_settings() -prb_calc_retire_blk_tmo - use __dev_get_by_index() and lock around it and __ethtool_get_settings() call v1->v2: add missing export_symbol Reviewed-by: Ben Hutchings <bhutchings@solarflare.com> [except FCoE bits] Acked-by: Ralf Baechle <ralf@linux-mips.org> Signed-off-by: David S.

Since these checks and initialization are done in dev_ethtool_get_settings called later on, remove this redundancy. Signed-off-by: Jiri Pirko <jpirko@redhat.com> Acked-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2011-08-25bridge: fix a possible use after freeEric Dumazet
br_multicast_ipv6_rcv() can call pskb_trim_rcsum() and therefore skb head can be reallocated. Cache icmp6_type field instead of dereferencing twice the struct icmp6hdr pointer. Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
