2011-06-07xfrm: Fix off by one in the replay advance functionsSteffen Klassert
We may write 4 byte too much when we reinitialize the anti replay window in the replay advance functions. This patch fixes this by adjusting the last index of the initialization loop. Signed-off-by: Steffen Klassert <steffen.klassert@secunet.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2011-06-07mac80211: Stop BA session event from deviceShahar Levi
Some devices support BT/WLAN co-existence algorigthms. In order not to harm the system performance and user experience, the device requests not to allow any RX BA session and tear down existing RX BA sessions based on system constraints such as periodic BT activity that needs to limit WLAN activity (eg.SCO or A2DP). In such cases, the intention is to limit the duration of the RX PPDU and therefore prevent the peer device to use A-MPDU aggregation. Adding ieee80211_stop_rx_ba_session() callback that can be used by the driver to stop existing BA sessions. Signed-off-by: Shahar Levi <shahar_levi@ti.com> Signed-off-by: John W.

2011-06-07nl80211: fix overflow in ssid_lenLuciano Coelho
When one of the SSID's length passed in a scan or sched_scan request is larger than 255, there will be an overflow in the u8 that is used to store the length before checking. This causes the check to fail and we overrun the buffer when copying the SSID. Fix this by checking the nl80211 attribute length before copying it to the struct. This is a follow up for the previous commit 208c72f4fe44fe09577e7975ba0e7fa0278f3d03, which didn't fix the problem entirely.

2011-06-07net: cpu offline cause napi stallHeiko Carstens
Frank Blaschka reported : <quote> During heavy network load we turn off/on cpus. Sometimes this causes a stall on the network device. Digging into the dump I found out following: napi is scheduled but does not run. From the I/O buffers and the napi state I see napi/rx_softirq processing has stopped because the budget was reached. napi stays in the softnet_data poll_list and the rx_softirq was raised again. I assume at this time the cpu offline comes in, the rx softirq is raised/moved to another cpu but napi stays in the poll_list of the softnet_data of the now offline cpu. Reviewing dev_cpu_callback (net/core/dev.c) I did not find the poll_list is transfered to the new cpu. </quote> This patch is a straightforward implementation of Frank suggestion : Transfert poll_list and trigger NET_RX_SOFTIRQ on new cpu.

Commit b0b0c0a26e84 "nfsd: add proc file listing kernel's gss_krb5 enctypes" added an nunnecessary dependency of nfsd on the auth_rpcgss module. It's a little ad hoc, but since the only piece of information nfsd needs from rpcsec_gss_krb5 is a single static string, one solution is just to share it with an include file.

2011-06-06ipvs: restore support for iptables SNATJulian Anastasov
Fix the IPVS priority in LOCAL_IN hook, so that SNAT target in POSTROUTING is supported for IPVS traffic as in 2.6.36 where it worked depending on module load order. Before 2.6.37 we used priority 100 in LOCAL_IN to process remote requests. We used the same priority as iptables SNAT and if IPVS handlers are installed before SNAT handlers we supported SNAT in POSTROUTING for the IPVS traffic. If SNAT is installed before IPVS, the netfilter handlers are before IPVS and netfilter checks the NAT table twice for the IPVS requests: once in LOCAL_IN where IPS_SRC_NAT_DONE is set and second time in POSTROUTING where the SNAT rules are ignored because IPS_SRC_NAT_DONE was already set in LOCAL_IN. But in 2.6.37 we changed the IPVS priority for LOCAL_IN with the goal to be unique (101) forgetting the fact that for IPVS traffic we should not walk both LOCAL_IN and POSTROUTING nat tables. So, change the priority for processing remote IPVS requests from 101 to 99, i.e. before NAT_SRC (100) because we prefer to support SNAT in POSTROUTING instead of LOCAL_IN. It also moves the priority for IPVS replies from 99 to 98. Use constants instead of magic numbers at these places.

2011-06-02net: tracepoint of net_dev_xmit sees freed skb and causes panicKoki Sanagi
Because there is a possibility that skb is kfree_skb()ed and zero cleared after ndo_start_xmit, we should not see the contents of skb like skb->len and skb->dev->name after ndo_start_xmit. But trace_net_dev_xmit does that and causes panic by NULL pointer dereference. This patch fixes trace_net_dev_xmit not to see the contents of skb directly. If you want to reproduce this panic, 1. Get tracepoint of net_dev_xmit on 2. Create 2 guests on KVM 2. Make 2 guests use virtio_net 4.

2011-06-01af-packet: Add flag to distinguish VID 0 from no-vlan.Ben Greear
Currently, user-space cannot determine if a 0 tcp_vlan_tci means there is no VLAN tag or the VLAN ID was zero. Add flag to make this explicit. User-space can check for TP_STATUS_VLAN_VALID || tp_vlan_tci > 0, which will be backwards compatible. Older could would have just checked for tp_vlan_tci, so it will work no worse than before.

This adds dump support to testmode. The testmode dump support in nl80211 requires using two of the six cb->args, the rest can be used by the driver to figure out where the dump position is at or to store other data across invocations.

2011-06-01cfg80211: don't drop p2p probe responsesEliad Peller
Commit 0a35d36 ("cfg80211: Use capability info to detect mesh beacons") assumed that probe response with both ESS and IBSS bits cleared means that the frame was sent by a mesh sta. However, these capabilities are also being used in the p2p_find phase, and the mesh-validation broke it. Rename the WLAN_CAPABILITY_IS_MBSS macro, and verify that mesh ies exist before assuming this frame was sent by a mesh sta. Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: John W.
