2013-02-13bridge: Dump vlan information from a bridge portVlad Yasevich4-16/+99
Using the RTM_GETLINK dump the vlan filter list of a given bridge port. The information depends on setting the filter flag similar to how nic VF info is dumped. Signed-off-by: Vlad Yasevich <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2013-02-13bridge: Add netlink interface to configure vlans on bridge portsVlad Yasevich5-18/+196
Add a netlink interface to add and remove vlan configuration on bridge port. The interface uses the RTM_SETLINK message and encodes the vlan configuration inside the IFLA_AF_SPEC. It is possble to include multiple vlans to either add or remove in a single message. Signed-off-by: Vlad Yasevich <[email protected]> Signed-off-by: David S. Miller <[email protected]>

2013-02-13bridge: Add vlan filtering infrastructureVlad Yasevich6-0/+296
Adds an optional infrustructure component to bridge that would allow native vlan filtering in the bridge. Each bridge port (as well as the bridge device) now get a VLAN bitmap. Each bit in the bitmap is associated with a vlan id. This way if the bit corresponding to the vid is set in the bitmap that the packet with vid is allowed to enter and exit the port. Write access the bitmap is protected by RTNL and read access protected by RCU. Vlan functionality is disabled by default. Signed-off-by: Vlad Yasevich <[email protected]> Signed-off-by: David S.

In order to avoid any future surprises of kernel panics due to jprobes function mismatches (as e.g. fixed in 4cb9d6eaf85ecd: sctp: jsctp_sf_eat_sack: fix jprobes function signature mismatch), we should check both function types during build and scream loudly if they do not match. __same_type resolves to __builtin_types_compatible_p, which is 1 in case both types are the same and 0 otherwise, qualifiers are ignored.

2013-02-13net: sctp: sctp_v6_get_dst: fix boolean test in dst cacheDaniel Borkmann1-2/+3
We walk through the bind address list and try to get the best source address for a given destination. However, currently, we take the 'continue' path of the loop when an entry is invalid (!laddr->valid) *and* the entry state does not equal SCTP_ADDR_SRC (laddr->state != SCTP_ADDR_SRC). Thus, still, invalid entries with SCTP_ADDR_SRC might not 'continue' as well as valid entries with SCTP_ADDR_{NEW, SRC, DEL}, with a possible false baddr and matchlen as a result, causing in worst case dst route to be false or possibly NULL. This test should actually be a '||' instead of '&&'. But lets fix it and make this a bit easier to read by having the condition the same way as similarly done in sctp_v4_get_dst.

2013-02-13batman-adv: Fix NULL pointer dereference in DAT hash collision avoidancePau Koning1-1/+1
An entry in DAT with the hashed position of 0 can cause a NULL pointer dereference when the first entry is checked by batadv_choose_next_candidate. This first candidate automatically has the max value of 0 and the max_orig_node of NULL. Not checking max_orig_node for NULL in batadv_is_orig_node_eligible will lead to a NULL pointer dereference when checking for the lowest address. This problem was added in 785ea1144182c341b8b85b0f8180291839d176a8 ("batman-adv: Distributed ARP Table - create DHT helper functions").

2013-02-13net: Fix possible wrong checksum generation.Pravin B Shelar7-12/+8
Patch cef401de7be8c4e (net: fix possible wrong checksum generation) fixed wrong checksum calculation but it broke TSO by defining new GSO type but not a netdev feature for that type. net_gso_ok() would not allow hardware checksum/segmentation offload of such packets without the feature. Following patch fixes TSO and wrong checksum. This patch uses same logic that Eric Dumazet used. Patch introduces new flag SKBTX_SHARED_FRAG if at least one frag can be modified by the user. but SKBTX_SHARED_FRAG flag is kept in skb shared info tx_flags rather than gso_type. tx_flags is better compared to gso_type since we can have skb with shared frag without gso packet. It does not link SHARED_FRAG to GSO, So there is no need to define netdev feature for this. Signed-off-by: Pravin B Shelar <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2013-02-13tcp: send packets with a socket timestampAndrey Vagin5-17/+30
A socket timestamp is a sum of the global tcp_time_stamp and a per-socket offset. A socket offset is added in places where externally visible tcp timestamp option is parsed/initialized. Connections in the SYN_RECV state are not supported, global tcp_time_stamp is used for them, because repair mode doesn't support this state. In a future it can be implemented by the similar way as for TIME_WAIT sockets. Cc: "David S.

2013-02-13tcp: adding a per-socket timestamp offsetAndrey Vagin2-0/+4
This functionality is used for restoring tcp sockets. A tcp timestamp depends on how long a system has been running, so it's differ for each host. The solution is to set a per-socket offset. A per-socket offset for a TIME_WAIT socket is inherited from a proper tcp socket. tcp_request_sock doesn't have a timestamp offset, because the repair mode for them are not implemented. Cc: "David S.

Current act_police uses rate table computed by the "tc" userspace program, which has the following issue: The rate table has 256 entries to map packet lengths to token (time units). With TSO sized packets, the 256 entry granularity leads to loss/gain of rate, making the token bucket inaccurate. Thus, instead of relying on rate table, this patch explicitly computes the time and accounts for packet transmission times with nanosecond granularity.

commit (32f5376 netfilter: nf_ct_helper: disable automatic helper re-assignment of different type) broke transparent proxy scenarios. For example, initial helper lookup might yield "ftp" (dport 21), while re-lookup after REDIRECT yields "ftp-2121". This causes the autoassign code to toss the ftp helper, even though these are just different instances of the same helper.

2013-02-11netpoll: Fix __netpoll_rcu_free so that it can hold the rtnl lockNeil Horman3-8/+12
__netpoll_rcu_free is used to free netpoll structures when the rtnl_lock is already held. The mechanism is used to asynchronously call __netpoll_cleanup outside of the holding of the rtnl_lock, so as to avoid deadlock. Unfortunately, __netpoll_cleanup modifies pointers (dev->np), which means the rtnl_lock must be held while calling it. Further, it cannot be held, because rcu callbacks may be issued in softirq contexts, which cannot sleep. Fix this by converting the rcu callback to a work queue that is guaranteed to get scheduled in process context, so that we can hold the rtnl properly while calling __netpoll_cleanup Tested successfully by myself.

2013-02-11mac80211: Add flushes before going off-channelSeth Forshee2-0/+8
We've got a couple of races when enabling powersave with an AP for off-channel operation. The first is fairly simple. If we go off-channel before the nullfunc frame to enable PS is transmitted then it may not be received by the AP. Add a flush after enabling off-channel PS to prevent this from happening. The second race is a bit more subtle. If the driver supports QoS and has frames queued when the nullfunc frame is queued, those frames may get transmitted after the nullfunc frame. If PM is not set then the AP is being told that we've exited PS before we go off-channel and may try to deliver frames. To prevent this, add a flush after stopping the queues but before passing the nullfunc frame to the driver.

2013-02-11mac80211: Fix tx queue handling during scansSeth Forshee6-25/+36
Scans currently work by stopping the netdev tx queues but leaving the mac80211 queues active. This stops the flow of incoming packets while still allowing mac80211 to transmit nullfunc and probe request frames to facilitate scanning. However, the driver may try to wake the mac80211 queues while in this state, which will also wake the netdev queues. To prevent this, add a new queue stop reason, IEEE80211_QUEUE_STOP_REASON_OFFCHANNEL, to be used when stopping the tx queues for off-channel operation. This prevents the netdev queues from waking when a driver wakes the mac80211 queues. This also stops all frames from being transmitted, even those meant to be sent off-channel. Add a new tx control flag, IEEE80211_TX_CTL_OFFCHAN_TX_OK, which allows frames to be transmitted when the queues are stopped only for the off-channel stop reason. Update all locations transmitting off-channel frames to use this flag. Signed-off-by: Seth Forshee <[email protected]> Signed-off-by: Johannes Berg <[email protected]>
