* tun: Fix/rewrite packet filtering logicMax Krasnyansky2008-07-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Please see the following thread to get some context on this http://marc.info/?l=linux-netdev&m=121564433018903&w=2 Basically the issue is that current multi-cast filtering stuff in the TUN/TAP driver is seriously broken. Original patch went in without proper review and ACK. It was broken and confusing to start with and subsequent patches broke it completely. To give you an idea of what's broken here are some of the issues: - Very confusing comments throughout the code that imply that the character device is a network interface in its own right, and that packets are passed between the two nics. Which is completely wrong. - Wrong set of ioctls is used for setting up filters. They look like shortcuts for manipulating state of the tun/tap network interface but in reality manipulate the state of the TX filter. - ioctls that were originally used for setting address of the the TX filter got "fixed" and now set the address of the network interface itself. Which made filter totaly useless. - Filtering is done too late. Instead of filtering early on, to avoid unnecessary wakeups, filtering is done in the read() call. The list goes on and on :) So the patch cleans all that up. It introduces simple and clean interface for setting up TX filters (TUNSETTXFILTER + tun_filter spec) and does filtering before enqueuing the packets. TX filtering is useful in the scenarios where TAP is part of a bridge, in which case it gets all broadcast, multicast and potentially other packets when the bridge is learning. So for example Ethernet tunnelling app may want to setup TX filters to avoid tunnelling multicast traffic. QEMU and other hypervisors can push RX filtering that is currently done in the guest into the host context therefore saving wakeups and unnecessary data transfer.

* ipv4: Fix ipmr unregister device oopsWang Chen2008-07-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | An oops happens during device unregister. The following oops happened when I add two tunnels, which use a same device, and then delete one tunnel. Obviously deleting tunnel "A" causes device unregister, which send a notification, and after receiving notification, ipmr do unregister again for tunnel "B" which also use same device. That is wrong. After receiving notification, ipmr only needs to decrease reference count and don't do duplicated unregister. Fortunately, IPv6 side doesn't add tunnel in ip6mr, so it's clean. This patch fixs: - unregister device oops - using after dev_put() Here is the oops: === Jul 11 15:39:29 wangchen kernel: ------------[ cut here ]------------ Jul 11 15:39:29 wangchen kernel: kernel BUG at net/core/dev.c:3651!

In bond_alb and bond_main, we check all positive increment for promiscuity and allmulti to get error return. But there are still two problems left. 1. Some code path has no mechanism to signal errors upstream. 2. If there are multi slaves, it's hard to tell which slaves increment promisc/allmulti successfully and which failed. So I left these problems to be FIXME. Fortunately, the overflow is very rare case. Signed-off-by: Wang Chen <wangchen@cn.fujitsu.com> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes mac80211 assign proper sequence numbers to QoS-data frames. It also removes the old sequence number code because we noticed that only the driver or hardware can assign sequence numbers to non-QoS-data and especially management frames in a race-free manner because beacons aren't passed through mac80211's TX path. This patch also adds temporary code to the rt2x00 drivers to not break them completely, that code will have to be reworked for proper sequence numbers on beacons. It also moves sequence number assignment down in the TX path so no sequence numbers are assigned to frames that are dropped.

| | | | | | | | | | | | | | | | | | | | | | | | This patch fixes the check at the entrance to ieee80211_rx_reorder_ampdu. This check has been broken by 'mac80211: rx.c use new helpers'. Letting QoS NULL packet in ieee80211_rx_reorder_ampdu led to packet loss in RX.

| * rt2x00: Reorganize beacon handlingIvo van Doorn2008-07-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | With the new beacon handling from mac80211 we can reorganize the beacon handling in rt2x00 as well. This patch will move the function to the TX handlers, and move all duplicate code into rt2x00queue.c. After this change the descriptor helper functions from rt2x00queue.c no longer need to be exported outside of rt2x00lib and can be declared static.

| * mac80211: revamp beacon configurationJohannes Berg2008-07-14
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch changes mac80211's beacon configuration handling to never pass skbs to the driver directly but rather always require the driver to use ieee80211_beacon_get(). Additionally, it introduces "change flags" on the config_interface() call to enable drivers to figure out what is changing. Finally, it removes the beacon_update() driver callback in favour of having IBSS beacon delivered by ieee80211_beacon_get() as well.

| * mac80211: make master netdev handling saneJohannes Berg2008-07-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, almost every interface type has a 'bss' pointer pointing to BSS information. This BSS information, however, is for a _local_ BSS, not for the BSS we joined, so having it on a STA mode interface makes little sense, but now they have it pointing to the master device, which is an AP mode virtual interface. However, except for some bitrate control data, this pointer is only used in AP/VLAN modes (for power saving stations.) Overall, it is not necessary to even have the master netdev be a valid virtual interface, and it doesn't have to be on the list of interfaces either. This patch changes the master netdev to be special, it now - no longer is on the list of virtual interfaces, which lets me remove a lot of tests for that - no longer has sub_if_data attached, since that isn't used Additionally, this patch changes some vlan/ap mode handling that is related to these 'bss' pointers described above (but in the VLAN case they actually make sense because there they point to the AP they belong to); it also adds some debugging code to IEEE80211_DEV_TO_SUB_IF to validate it is not called on the master netdev any more.

| * rt2x00: Fix NULL pointer error in adhoc/master modeIvo van Doorn2008-07-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As soon as an interface is enabled, and that interface is in adhoc or master mode, the device will start raising beacondone interrupts. But before the first interrupt is raised, mac80211 will probably not have send any beacons to the device yet, which results in a NULL pointer error when the skb is being freed. Note that the "raise beacondone interrupts without a beacon" is also a bug, and will be addressed later. The more important bug however is preventing the NULL pointer failt itself, since there might be other conditions that could trigger it as well.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This corrects an error in the computation of the open loss interval I_0: * the interval length is (highest_seqno - start_seqno) + 1 * and not (highest_seqno - start_seqno). This condition was not fully clear in RFC 3448, but reflects the current revision state of rfc3448bis and is also consistent with RFC 4340, 6.1.1. Further changes: ---------------- * variable renamed due to line length constraints; * explicit typecast to `s64' to avoid implicit signed/unsigned casting.

To avoid further and similar problems, all loss handling and loss detection is now done inside tfrc_rx_hist_handle_loss(), using an appropriate routine to track new losses. Further changes: ---------------- * added a reminder that no RX history operations should be performed when rx_handle_loss() has identified a (new) loss, since the function takes care of packet reordering during loss detection; * made tfrc_rx_hist_loss_pending() bool (thanks to an earlier suggestion by Arnaldo); * removed unused functions.
