2010-06-15cnic: Fix cnic_cm_abort() error handling.Michael Chan1-11/+18
Fix the code that handles the error case when cnic_cm_abort() cannot proceed normally. We cannot just set the csk->state and we must go through cnic_ready_to_close() to handle all the conditions. We also add error return code in cnic_cm_abort(). Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: Eddie Wai <waie@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>

In particular, we need to (test_and_clear_bit(SK_F_OFFLD_COMPLETE, &csk->flags)) before we update csk->state.

2010-06-15bridge: Fix netpoll supportHerbert Xu4-84/+120
There are multiple problems with the newly added netpoll support: 1) Use-after-free on each netpoll packet. 2) Invoking unsafe code on netpoll/IRQ path. 3) Breaks when netpoll is enabled on the underlying device. This patch fixes all of these problems. In particular, we now allocate proper netpoll structures for each underlying device. We only allow netpoll to be enabled on the bridge when all the devices underneath it support netpoll. Once it is enabled, we do not allow non-netpoll devices to join the bridge (until netpoll is disabled again). This allows us to do away with the npinfo juggling that caused problem number 1. Incidentally this patch fixes number 2 by bypassing unsafe code such as multicast snooping and netfilter.

2010-06-15netpoll: Add netpoll_tx_runningHerbert Xu1-0/+9
This patch adds the helper netpoll_tx_running for use within ndo_start_xmit. It returns non-zero if ndo_start_xmit is being invoked by netpoll, and zero otherwise. This is currently implemented by simply looking at the hardirq count. This is because for all non-netpoll uses of ndo_start_xmit, IRQs must be enabled while netpoll always disables IRQs before calling ndo_start_xmit.

2010-06-15netpoll: Allow netpoll_setup/cleanup recursionHerbert Xu2-79/+99
This patch adds the functions __netpoll_setup/__netpoll_cleanup which is designed to be called recursively through ndo_netpoll_seutp. They must be called with RTNL held, and the caller must initialise np->dev and ensure that it has a valid reference count.

2010-06-15netpoll: Add locking for netpoll_setup/cleanupHerbert Xu1-75/+76
As it stands, netpoll_setup and netpoll_cleanup have no locking protection whatsoever. So chaos ensures if two entities try to perform them on the same device. This patch adds RTNL to the equation. The code has been rearranged so that bits that do not need RTNL protection are now moved to the top of netpoll_setup. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

2010-06-15netpoll: Fix RCU usageHerbert Xu2-13/+20
The use of RCU in netpoll is incorrect in a number of places: 1) The initial setting is lacking a write barrier. 2) The synchronize_rcu is in the wrong place. 3) Read barriers are missing. 4) Some places are even missing rcu_read_lock. 5) npinfo is zeroed after freeing. This patch fixes those issues. As most users are in BH context, this also converts the RCU usage to the BH variant. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Acked-by: Paul E.

2010-06-15netfilter: xtables: idletimer target implementationLuciano Coelho5-0/+373
This patch implements an idletimer Xtables target that can be used to identify when interfaces have been idle for a certain period of time. Timers are identified by labels and are created when a rule is set with a new label. The rules also take a timeout value (in seconds) as an option. If more than one rule uses the same timer label, the timer will be restarted whenever any of the rules get a hit. One entry for each timer is created in sysfs. This attribute contains the timer remaining for the timer to expire. The attributes are located under the xt_idletimer class: /sys/class/xt_idletimer/timers/<label> When the timer expires, the target module sends a sysfs notification to the userspace, which can then decide what to do (eg. disconnect to save power).

2010-06-13ixgbe: fix automatic LRO/RSC settings for low latencyAndy Gospodarek1-29/+8
This patch added to 2.6.34: commit f8d1dcaf88bddc7f282722ec1fdddbcb06a72f18 Author: Jesse Brandeburg <jesse.brandeburg@intel.com> Date: Tue Apr 27 01:37:20 2010 +0000 ixgbe: enable extremely low latency introduced a feature where LRO (called RSC on the hardware) was disabled automatically when setting rx-usecs to 0 via ethtool. Some might not like the fact that LRO was disabled automatically, but I'm fine with that. What I don't like is that LRO/RSC is automatically enabled when rx-usecs is set >0 via ethtool. This would certainly be a problem if the device was used for forwarding and it was determined that the low latency wasn't needed after the device was already forwarding. I played around with saving the state of LRO in the driver, but it just didn't seem worthwhile and would require a small change to dev_disable_lro() that I did not like. This patch simply leaves LRO disabled when setting rx-usecs >0 and requires that the user enable it again. An extra informational message will also now appear in the log so users can understand why LRO isn't being enabled as they expect. Inconsistency of LRO setting first noticed by Stanislaw Gruszka.
