Increase fragmentation hash bucket size to 1024 from old 64 elems. After we increased the frag mem limits commit c2a93660 (net: increase fragment memory usage limits) the hash size of 64 elements is simply too small. Also considering the mem limit is per netns and the hash table is shared for all netns. For the embedded people, note that this increase will change the hash table/array from using approx 1 Kbytes to 16 Kbytes. Signed-off-by:

ARM cannot handle udelay for more than 2 miliseconds, and it is rather bad style to block the cpu for 16ms anyway, so let's use msleep instead. Signed-off-by:

Nicolas Dichtel says: ==================== The goal of this patchset is to be able to get all infos exported via the /proc/net/packet and also beeing able to get filter associated to af_packet sockets. As usual, the patch against iproute2 will be sent once the patches are included and net-next merged. I can send it on demand. ==================== Signed-off-by: -

This patch allows to dump BPF filters attached to a socket with SO_ATTACH_FILTER. Note that we check CAP_SYS_ADMIN before allowing to dump this info. For now, only AF_PACKET sockets use this feature. Signed-off-by:

Testing like this for TP_STATUS_AVAILABLE clearly is a stupid bug since it always returns true. Fix this by only checking for flags where the kernel owns the packet and negate this result, since we also could run into the non-zero status TP_STATUS_WRONG_FORMAT and need to reclaim frames.

Source compatiability for build iproute2 was broken by: commit c7995c43 Author: Atzm Watanabe <atzm@stratosphere.co.jp> vxlan: Allow setting destination to unicast address. Since this commit has not made it upstream (still net-next), and better to avoid gratitious changes to exported API's; go back to original definition, and add a comment. Signed-off-by:

The NDA_PORT attribute was added, but the author wasn't careful about width (port is 16 bits), or byte order. The attribute was being dumped as 16 bits, but only 32 bit value would be accepted when setting up a device. Also, the remote port is in network byte order and was being compared with default port in host byte order. Signed-off-by:

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: -

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:

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:

This patch add struct mlx4_vport_state where all the parameters related to management of VFs port (virtual ports of the NIC eswitch) are kept.

Add reference counting to the driver MAC registeration code. This would be needed for cases where a mac is registered from more than once, e.g when both the host and the VM driver register the same mac, the host for mac spoof protection purposes and the VM for its regular needs. Signed-off-by:

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. Signed-off-by:

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. In addition it removes a read of AUTOC and uses the stored value to force the link up. Signed-off-by:

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. CC: stable <stable@vger.kernel.org> Signed-off-by:

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:

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. Signed-off-by:Sebastian Andrzej Siewior <bigeasy@linutronix.de> Acked-by:

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.
