| * [NET_SCHED]: act_api: qdisc internal reclassify supportPatrick McHardy2007-07-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The behaviour of NET_CLS_POLICE for TC_POLICE_RECLASSIFY was to return it to the qdisc, which could handle it internally or ignore it. With NET_CLS_ACT however, tc_classify starts over at the first classifier and never returns it to the qdisc. This makes it impossible to support qdisc-internal reclassification, which in turn makes it impossible to remove the old NET_CLS_POLICE code without breaking compatibility since we have two qdiscs (CBQ and ATM) that support this. This patch adds a tc_classify_compat function that handles reclassification the old way and changes CBQ and ATM to use it. This again is of course not fully backwards compatible with the previous NET_CLS_ACT behaviour. Unfortunately there is no way to fully maintain compatibility *and* support qdisc internal reclassification with NET_CLS_ACT, but this seems like the better choice over keeping the two incompatible options around forever.

| * [IPV6]: MSG_ERRQUEUE messages do not pass to connected raw socketsDmitry Butskoy2007-07-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From: Dmitry Butskoy <dmitry@butskoy.name> Taken from http://bugzilla.kernel.org/show_bug.cgi?id=8747 Problem Description: It is related to the possibility to obtain MSG_ERRQUEUE messages from the udp and raw sockets, both connected and unconnected. There is a little typo in net/ipv6/icmp.c code, which prevents such messages to be delivered to the errqueue of the correspond raw socket, when the socket is CONNECTED. The typo is due to swap of local/remote addresses. Consider __raw_v6_lookup() function from net/ipv6/raw.c. When a raw socket is looked up usual way, it is something like: sk = __raw_v6_lookup(sk, nexthdr, daddr, saddr, IP6CB(skb)->iif); where "daddr" is a destination address of the incoming packet (IOW our local address), "saddr" is a source address of the incoming packet (the remote end). But when the raw socket is looked up for some icmp error report, in net/ipv6/icmp.c:icmpv6_notify() , daddr/saddr are obtained from the echoed fragment of the "bad" packet, i.e. "daddr" is the original destination address of that packet, "saddr" is our local address. Hence, for icmpv6_notify() must use "saddr, daddr" in its arguments, not "daddr, saddr" ... Steps to reproduce: Create some raw socket, connect it to an address, and cause some error situation: f.e. set ttl=1 where the remote address is more than 1 hop to reach. Set IPV6_RECVERR . Then send something and wait for the error (f.e. poll() with POLLERR|POLLIN). You should receive "time exceeded" icmp message (because of "ttl=1"), but the socket do not receive it. If you do not connect your raw socket, you will receive MSG_ERRQUEUE successfully. (The reason is that for unconnected socket there are no actual checks for local/remote addresses).

The entire optimization is a bit questionable IMO, it moves potentially large parts of NET_TX_SOFTIRQ work to TIMER_SOFTIRQ/HRTIMER_SOFTIRQ, which kind of defeats the separation of them.

| * [NETFILTER]: nf_conntrack: Don't track locally generated special ICMP errorYasuyuki Kozakai2007-07-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The conntrack assigned to locally generated ICMP error is usually the one assigned to the original packet which has caused the error. But if the original packet is handled as invalid by nf_conntrack, no conntrack is assigned to the original packet. Then nf_ct_attach() cannot assign any conntrack to the ICMP error packet. In that case the current nf_conntrack_icmp assigns appropriate conntrack to it. But the current code mistakes the direction of the packet. As a result, NAT code mistakes the address to be mangled. To fix the bug, this changes nf_conntrack_icmp not to assign conntrack to such ICMP error. Actually no address is necessary to be mangled in this case. Spotted by Jordan Russell.

| | * [PATCH] mac80211: improved 802.11g CTS protectionDaniel Drake2007-07-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, CTS protection is partially implemented twice: 1. via prism2 ioctls, only used by hostapd 2. via STA beacon parsing, recorded in sta.use_protection but never used (other than printed in debugfs) Protection control should be implemented on a per-subif basis. For example, a single physical device may be running a soft AP on one channel, and a STA on another. The AP interface should use protection based on what hostapd told it, and the STA interface should use protection based on beacon parsing. These should operate independantly: one subif using protection should not influence the other. To implement this, I moved the use_protection flag into ieee80211_sub_if_data and removed the device-global cts_protect_erp_frames flag. I also made the PRISM2_PARAM_CTS_PROTECT_ERP_FRAMES write operation only available for AP interfaces, to avoid any possibility of the user messing with the behaviour of a STA.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The "protection needed" flag is currently parsed out of the ERP IE in beacons. This patch allows the ERP IE to be available at assocation time and causes the appropriate actions to be performed earlier. It is slightly complicated by the fact that most APs don't include the ERP IE in association responses. To work around this, we store ERP values in the ieee80211_sta_bss structure. Also added some WLAN_ERP defines for use by upcoming patches. Signed-off-by: Jiri Benc <jbenc@suse.cz> Signed-off-by: John W. Linville <linville@tuxdriver.com>

| * | [VLAN]: Fix promiscous/allmulti synchronization racesPatrick McHardy2007-07-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The set_multicast_list function may be called without holding the rtnl mutex, resulting in races when changing the underlying device's promiscous and allmulti state. Use the change_rx_mode hook, which is always invoked under the rtnl. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
| * | [NET]: dev_mcast: add multicast list synchronization helpersPatrick McHardy2007-07-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The method drivers currently use to synchronize multicast lists is not very pretty: - walk the multicast list - search each entry on a copy of the previous list - if new add to lower device - walk the copy of the previous list - search each entry on the current list - if removed delete from lower device - copy entire list This patch adds a new field to struct dev_addr_list to store the synchronization state and adds two helper functions for synchronization and cleanup.

| * | [NET]: Add net_device change_rx_mode callbackPatrick McHardy2007-07-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the set_multicast_list (and set_rx_mode) callbacks are responsible for configuring the device according to the IFF_PROMISC, IFF_MULTICAST and IFF_ALLMULTI flags and the mc_list (and uc_list in case of set_rx_mode). These callbacks can be invoked from BH context without the rtnl_mutex by dev_mc_add/dev_mc_delete, which makes reading the device flags and promiscous/allmulti count racy. For real hardware drivers that just commit all changes to the hardware this is not a real problem since the stack guarantees to call them for every change, so at least the final call will not race and commit the correct configuration to the hardware. For software devices that want to synchronize promiscous and multicast state to an underlying device however this can cause corruption of the underlying device's flags or promisc/allmulti counts. When the software device is concurrently put in promiscous or allmulti mode while set_multicast_list is invoked from bottem half context, the device might synchronize the change to the underlying device without holding the rtnl_mutex, which races with concurrent changes to the underlying device. Add a dev->change_rx_flags hook that is invoked when any of the flags that affect rx filtering change (under the rtnl_mutex), which allows drivers to perform synchronization immediately and only synchronize the address lists in set_multicast_list/set_rx_mode.
