Unlike tcm_vhost_evt requests, tcm_vhost_cmd requests are passed to the target core system, we can not make sure all the pending requests will be finished by flushing the virt queue. In this patch, we do refcount for every tcm_vhost_cmd requests to make vhost_scsi_flush() wait for all the pending requests issued before the flush operation to be finished. This is useful when we call vhost_scsi_clear_endpoint() to stop tcm_vhost. No new requests will be passed to target core system because we clear the endpoint by setting vs_tpg to NULL. And we wait for all the old requests. These guarantee no requests will be leaked and existing requests will be completed. Signed-off-by: Asias He <asias@redhat.com> Signed-off-by: Michael S.

This is useful for any device who wants device specific fields per vq. For example, tcm_vhost wants a per vq field to track requests which are in flight on the vq. Also, on top of this we can add patches to move things like ubufs from vhost.h out to net.c. Signed-off-by: Michael S.

Jeff Kirsher says: ==================== This series contains updates to e1000e, igb and ixgbe. There are 2 patches in this series which could be applied to net, but since Linus is so very close to releasing 3.9, I do not think it prudent to try and push these into net at this time. I have CC'd stable on these patches so that they can queue them up as soon as 3.9 gets released. The 2 patches are: e1000e: fix numeric overflow in phc settime method ixgbe: fix EICR write in ixgbe_msix_other Richard provides a fix for e1000e by using a helper function from time.h to resolve a unintended overflow in the PTP settime function. Bruce provides a fix to wait for NAPI to be done with the current context after disabling interrupts and then disable NAPI when the interface is going down. This fixes a possible "unable to handle kernel paging request" panic in net-next. Andi Kleen provides a patch for igb to use mdelay instead of udelay when we needed 100000us. Jacob provides a fix for ixgbe to simply mask the lower 16bits off so that ixgbe_msix_other does not write them in the EICR, which causes them to remain high and be properly handled by the clean_rings interrupt routine as normal. Emil cleans up the logic in ixgbe_setup_loopback_test() to only access registers applicable to the MAC type. In addition, removes majority of the AUTOC register reads by using a cached value instead to avoid writing corrupted values to AUTOC due to bad FW. Emil also add support for disabling link during boot time. Lastly, he provides a patch which adds the MAC type to the version in ethtool_regs which will make it easier to check the MAC type when dumping registers with ethtool. There is a separate ethtool tool patch which is dependent upon Emil's last patch of the series to add the MAC type to the version in ethtool_regs, which will be sent separately. ==================== Signed-off-by: David S.

Or Gerlitz says: ==================== This series adds support for the SRIOV ndo_set_vf callbacks to the mlx4 driver. Series done against the net-next tree as of commit 37fe0660 "net: fix address check in rtnl_fdb_del" We have successfully tested the series on net-next, except for getting the VF link info issue I have reported earlier today on netdev, we see the problem for both ixgbe and mlx4 VFs. Just to make sure get VF config is working OK with patch #6 - we have run it over 3.8.8 too. We added to the V1 series two patches that disable HW timestamping when running over a VF, as this isn't supported yet. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

Add support to ndo_set_vf_vlan in the driver. Once this call is used the vport is considered to be in VST mode. In this mode, the PPF driver configures Ethernet QPs created by this VF to use this vlan id and priority. Currently RoCE isn't supported on that mode. The special values of VID=4095 or VID=0,UP=0 are considered as VGT. Signed-off-by: Rony Efraim <ronye@mellanox.com> Signed-off-by: Or Gerlitz <ogerlitz@mellanox.com> Signed-off-by: David S.

This patch adds the mac type to the version in ethtool_regs. This will make it easier to check the mac type when dumping registers with ethtool. The drawback of this is that older versions of ethtool will only be able to dump in hex format for 82599 and above when used with the updated driver.

This patch cleans up the logic in ixgbe_setup_loopback_test() to only access registers applicable to the MAC type. AUTOC is only valid on MACs older than X540. MACC is used for X540.

Previously, the ixgbe_msix_other was writing the full 32bits of the set interrupts, instead of only the ones which the ixgbe_msix_other is handling. This resulted in a loss of performance when the X540's PPS feature is enabled due to sometimes clearing queue interrupts which resulted in the driver not getting the interrupt for cleaning the q_vector rings often enough. The fix is to simply mask the lower 16bits off so that this handler does not write them in the EICR, which causes them to remain high and be properly handled by the clean_rings interrupt routine as normal.

The PTP Hardware Clock settime function in the e1000e driver computes nanoseconds from a struct timespec. The code converts the seconds field .tv_sec by multiplying it with NSEC_PER_SEC. However, both operands are of type long, resulting in an unintended overflow. The patch fixes the issue by using the helper function from time.h.

Commit 6681712d vxlan: generalize forwarding tables relaxed the address checks in rtnl_fdb_del() to use is_zero_ether_addr(). This allows users to add multicast addresses using the fdb API. However, the check in rtnl_fdb_del() still uses a more strict is_valid_ether_addr() which rejects multicast addresses. Thus it is possible to add an fdb that can not be later removed. Relax the check in rtnl_fdb_del() as well. Signed-off-by: Vlad Yasevich <vyasevic@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>

During high throughput it is likely that we receive both: an RX and TX interrupt. The normal behaviour is that once we enter the ISR the interrupts are disabled in the IRQ chip and so the ISR is invoked only once and the interrupt line is disabled once. It will be re-enabled after napi completes. With threaded interrupts on the other hand the interrupt the interrupt is disabled immediately and the ISR is marked for "later". By having TX and RX interrupt marked pending we invoke them both and disable the interrupt line twice. The napi callback is still executed once and so after it completes we remain with interrupts disabled. The initial patch simply removed the cpsw_{enable|disable}_irq() calls and it worked well on my AM335X ES1.0 (beagle bone). On ES2.0 (beagle bone black) it caused an never ending interrupt (even after the mask via cpsw_intr_disable()) according to Mugunthan V N. Since I don't have the ES2.0 and no idea what is going on this patch tracks the state of the irq_disable() call and execute it only when not yet done. The book keeping is done on the first struct since with dual_emac we can have two of those and only one interrupt line.

This driver does not clean up properly after leaving. Here is a list: - Use unregister_netdev(). free_netdev() is good but not enough - Use the above also on the other ndev in case of dual mac - Free data.slave_data. The name of the strucre makes it look like it is platform_data but it is not. It is just a trick! - Free all irqs. Again: freeing one irq is good start, but freeing all of them is better. With this rmmod & modprobe of cpsw seems to work. The remaining issue is: |WARNING: at fs/sysfs/dir.c:536 sysfs_add_one+0x9c/0xd4() |sysfs: cannot create duplicate filename '/devices/ocp.2/4a100000.ethernet/4a101000.mdio' |WARNING: at lib/kobject.c:196 kobject_add_internal+0x1a4/0x1c8() comming from of_platform_populate() and I am not sure that this belongs here.

In case that we run into OOM during the allocation of the new rx-skb we don't get one and we have one skb less than we used to have. If this continues to happen then we end up with no rx-skbs at all. This patch changes the following: - if we fail to allocate the new skb, then we treat the currently completed skb as the new one and so drop the currently received data. - instead of testing multiple times if the device is gone we rely one the status field which is set to -ENOSYS in case the channel is going down and incomplete requests are purged. cpdma_chan_stop() removes most of the packages with -ENOSYS. The currently active packet which is removed has the "tear down" bit set. So if that bit is set, we send ENOSYS as well otherwise we pass the status bits which are required to figure out which of the two possible just finished.

netif_running() reports false before the ->ndo_stop() callback is called. That means if one executes "ifconfig down" and the system receives an interrupt before the interrupt source has been disabled we hang for always for two reasons: - we never disable the interrupt source because devices claim to be already inactive and don't feel responsible. - since the ISR always reports IRQ_HANDLED the line is never deactivated because it looks like the ISR feels responsible. This patch changes the logic in the ISR a little: - If none of the status registers reports an active source (RX or TX, misc is ignored because it is not actived) we leave with IRQ_NONE. - the interrupt is deactivated - The first active network device is taken and napi is scheduled. If none are active (a small race window between ndo_down() and the interrupt the) then we leave and should not come back because the source is off. There is no need to schedule the second NAPI because both share the same dma queue.

if during "ifconfig up" we run out of mem we continue regardless how many skbs we got. In worst case we have zero RX skbs and can't ever receive further packets since the RX skbs are never reallocated. If cpdma_chan_submit() fails we even leak the skb. This patch changes the behavior here: If we fail to allocate an skb during bring up we don't continue and report that error. Same goes for errors from cpdma_chan_submit(). While here I changed to __netdev_alloc_skb_ip_align() so GFP_KERNEL can be used.
