2012-08-06net_sched: act: Delete estimator in error path.Hiroaki SHIMODA3-3/+14
Some action modules free struct tcf_common in their error path while estimator is still active. This results in est_timer() dereference freed memory. Add gen_kill_estimator() in ipt, pedit and simple action. Signed-off-by: Hiroaki SHIMODA <shimoda.hiroaki@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2012-08-06ip: fix error handling in ip_finish_output2()Vasiliy Kulikov1-1/+1
__neigh_create() returns either a pointer to struct neighbour or PTR_ERR(). But the caller expects it to return either a pointer or NULL. Replace the NULL check with IS_ERR() check. The bug was introduced in a263b3093641fb1ec377582c90986a7fd0625184 ("ipv4: Make neigh lookups directly in output packet path.").

2012-08-02cfg80211: add channel flag to prohibit OFDM operationSeth Forshee2-0/+4
Currently the only way for wireless drivers to tell whether or not OFDM is allowed on the current channel is to check the regulatory information. However, this requires hodling cfg80211_mutex, which is not visible to the drivers. Other regulatory restrictions are provided as flags in the channel definition, so let's do similarly with OFDM. This patch adds a new flag, IEEE80211_CHAN_NO_OFDM, to tell drivers that OFDM on a channel is not allowed. This flag is set on any channels for which regulatory indicates that OFDM is prohibited.

2012-08-02sfc: Fix maximum number of TSO segments and minimum TX queue sizeBen Hutchings4-9/+46
Currently an skb requiring TSO may not fit within a minimum-size TX queue. The TX queue selected for the skb may stall and trigger the TX watchdog repeatedly (since the problem skb will be retried after the TX reset). This issue is designated as CVE-2012-3412. Set the maximum number of TSO segments for our devices to 100. This should make no difference to behaviour unless the actual MSS is less than about 700. Increase the minimum TX queue size accordingly to allow for 2 worst-case skbs, so that there will definitely be space to add an skb after we wake a queue. To avoid invalidating existing configurations, change efx_ethtool_set_ringparam() to fix up values that are too small rather than returning -EINVAL.

2012-08-02net: Allow driver to limit number of GSO segments per skbBen Hutchings2-0/+6
A peer (or local user) may cause TCP to use a nominal MSS of as little as 88 (actual MSS of 76 with timestamps). Given that we have a sufficiently prodigious local sender and the peer ACKs quickly enough, it is nevertheless possible to grow the window for such a connection to the point that we will try to send just under 64K at once. This results in a single skb that expands to 861 segments. In some drivers with TSO support, such an skb will require hundreds of DMA descriptors; a substantial fraction of a TX ring or even more than a full ring. The TX queue selected for the skb may stall and trigger the TX watchdog repeatedly (since the problem skb will be retried after the TX reset). This particularly affects sfc, for which the issue is designated as CVE-2012-3412. Therefore: 1. Add the field net_device::gso_max_segs holding the device-specific limit. 2. In netif_skb_features(), if the number of segments is too high then mask out GSO features to force fall back to software GSO.

2012-08-01mac80211: cancel mesh path timerJohannes Berg1-0/+1
The mesh path timer needs to be canceled when leaving the mesh as otherwise it could fire after the interface has been removed already. Cc: stable@vger.kernel.org Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2012-08-01mac80211: clear timer bits when disconnectingJohannes Berg2-0/+4
There's a corner case that can happen when we suspend with a timer running, then resume and disconnect. If we connect again, suspend and resume we might start timers that shouldn't be running. Reset the timer flags to avoid this. This affects both mesh and managed modes. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
