tcp: bug fix Fast Open client retransmission

2012-12-07T19:39:28Z

If SYN-ACK partially acks SYN-data, the client retransmits the remaining data by tcp_retransmit_skb(). This increments lost recovery state variables like tp->retrans_out in Open state. If loss recovery happens before the retransmission is acked, it triggers the WARN_ON check in tcp_fastretrans_alert(). For example: the client sends SYN-data, gets SYN-ACK acking only ISN, retransmits data, sends another 4 data packets and get 3 dupacks. Since the retransmission is not caused by network drop it should not update the recovery state variables. Further the server may return a smaller MSS than the cached MSS used for SYN-data, so the retranmission needs a loop. Otherwise some data will not be retransmitted until timeout or other loss recovery events. Signed-off-by: Yuchung Cheng Acked-by: Neal Cardwell Signed-off-by: David S. Miller

xfrm: Fix the gc threshold value for ipv4

2012-11-13T08:15:07Z

The xfrm gc threshold value depends on ip_rt_max_size. This value was set to INT_MAX with the routing cache removal patch, so we start doing garbage collecting when we have INT_MAX/2 IPsec routes cached. Fix this by going back to the static threshold of 1024 routes. Signed-off-by: Steffen Klassert

mac80211: verify that skb data is present

2012-10-26T20:52:42Z

A number of places in the mesh code don't check that the frame data is present and in the skb header when trying to access. Add those checks and the necessary pskb_may_pull() calls. This prevents accessing data that doesn't actually exist. To do this, export ieee80211_get_mesh_hdrlen() to be able to use it in mac80211. Cc: stable@vger.kernel.org Signed-off-by: Johannes Berg

cfg80211/mac80211: avoid state mishmash on deauth

2012-10-15T15:21:34Z

Avoid situation when we are on associate state in mac80211 and on disassociate state in cfg80211. This can results on crash during modules unload (like showed on this thread: http://marc.info/?t=134373976300001&r=1&w=2) and possibly other problems.

ipv4: Add FLOWI_FLAG_KNOWN_NH

2012-10-08T21:42:36Z

Add flag to request that output route should be returned with known rt_gateway, in case we want to use it as nexthop for neighbour resolving. The returned route can be cached as follows: - in NH exception: because the cached routes are not shared with other destinations - in FIB NH: when using gateway because all destinations for NH share same gateway As last option, to return rt_gateway!=0 we have to set DST_NOCACHE.

ipv4: introduce rt_uses_gateway

2012-10-08T21:42:36Z

Add new flag to remember when route is via gateway. We will use it to allow rt_gateway to contain address of directly connected host for the cases when DST_NOCACHE is used or when the NH exception caches per-destination route without DST_NOCACHE flag, i.e. when routes are not used for other destinations. By this way we force the neighbour resolving to work with the routed destination but we can use different address in the packet, feature needed for IPVS-DR where original packet for virtual IP is routed via route to real IP.
