Pablo Neira Ayuso says: <pablo@netfilter.org> ==================== nftables updates for net-next The following patchset contains nftables updates for your net-next tree, they are: * Add set operation to the meta expression by means of the select_ops() infrastructure, this allows us to set the packet mark among other things. From Arturo Borrero Gonzalez. * Fix wrong format in sscanf in nf_tables_set_alloc_name(), from Daniel Borkmann. * Add new queue expression to nf_tables. These comes with two previous patches to prepare this new feature, one to add mask in nf_tables_core to evaluate the queue verdict appropriately and another to refactor common code with xt_NFQUEUE, from Eric Leblond. * Do not hide nftables from Kconfig if nfnetlink is not enabled, also from Eric Leblond. * Add the reject expression to nf_tables, this adds the missing TCP RST support. It comes with an initial patch to refactor common code with xt_NFQUEUE, again from Eric Leblond. * Remove an unused variable assignment in nf_tables_dump_set(), from Michal Nazarewicz. * Remove the nft_meta_target code, now that Arturo added the set operation to the meta expression, from me. * Add help information for nf_tables to Kconfig, also from me. * Allow to dump all sets by specifying NFPROTO_UNSPEC, similar feature is available to other nf_tables objects, requested by Arturo, from me. * Expose the table usage counter, so we can know how many chains are using this table without dumping the list of chains, from Tomasz Bursztyka. ==================== Signed-off-by: -

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates This series contains updates to i40e only. Majority of this series contains patches from Greg and Mitch to fix up or add functionality to the PF/VF driver interactions. Notably, a fix for SR-IOV VF port VLAN which resolved the problem of port VLAN configurations not being persistent across VF driver loads and unloads and enable/disable of the feature. Also do not enable the default port on the VEB, which is designed only to bridge the PF to an Open vSwitch or bridge. Another fix to resolve a possible memory corruption condition where ARQ messages are written to random memory locations. Fix a problem where the 'ip link show' command would display stale link address information after the link address was set via the 'ip link set' command. Anjali provides several patches, one which saves information that can be used while cleaning the Tx ring and useful in detecting Tx hangs. Then provides a fixes to the admin queue shutdown function to ensure we are shutting down the queue in the shutdown path and ensure ASQ is alive before issuing the admin queue command. Shannon provides a fix for get/update vsi params where the incorrect struct was being used. ==================== Signed-off-by: -

Always call the AQ call to shutdown the queue in the shutdown path. Check ASQ is alive before issuing the AQ command since we might be resetting to recover from a bad state in which case we should not issue the AQ command. Use the register variable for length so it can be used by PF, VF and GL AQ commands. Change-Id: Ic3d305687ea3f1a6afa84e864b7a27bd38a9af32 Signed-off-by:

When communicating with VF devices over the AQ, the FW refers to the VF by its global VF ID, not local the VF ID with reference to its parent PF. Since the global and local VF IDs are identical for PF 0, the code worked correctly on PF 0. However, we cannot just use global IDs throughout the code as most of the other references to the VF (VSI setup, register offsets, etc.) require the local VF ID. Instead, we just add or subtract our base VF ID when sending and receiving AQ messages. Change-Id: I92f4332b4876bc68b2f9af9ebf48761f63b6bd97 Signed-off-by:

When SR-IOV is disabled, the (now nonexistent) virtual function devices undergo a VFLR event. We don't need to handle this event because the VFs are gone, but we do need to tell the HW that they are complete. This fixes an issue with a phantom VFLR and broken VFs when SR-IOV is re-enabled.

Greg Rose authored
Enabling the default port on the VEB causes all outgoing traffic from virtual functions to be copied to the physical function. The default port is only supposed to be used if you wish to bridge the physical function to a SW switch such as Open vSwitch or the Linux bridge. That allows the SW switch to route traffic to VMs that are not using a virtual function. Eventually we'll want to implement the ndo_fdb_add, ndo_fdb_del, and ndo_fdb_dump functions. The ndo_fdb_add function would set the default port on the VEB in those cases where the MAC/VLAN address filters have overflowed. Normally we would not want to use it.

This patch fixes two different problems. 1) The port VLAN configuration was not persistent across VF driver loads and unloads. 2) The port VLAN configuration was only correct the first time it was set. Switching the port VLAN on and off would cause subsequent VLAN configurations to be corrupted in the VSI. Ensure that the correct bits are being set for the VSI port VLAN configuration.

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates This series contains updates to i40e only. Anjali provides two cleanups to remove unnecessary code and a fix to resolve debugfs dumping only half the NVM. Then provides a fix to ethtool NVM reads where shadow RAM was used instead of actual NVM reads. Jesse provides a couple of fixes, one removes custom i40e functions which duplicate existing kernel functionality. Second fixes constant cast issues by replacing __constant_htons with htons. Mitch provides a couple of fixes for the VF interfaces in i40e. First provides a fix to guard against VF message races with can cause a panic. Second fix reinitializes the buffer size each time we clean the ARQ, because subsequent messages can be truncated. Lastly adds functionality to enable/disable ICR 0 dynamically. Vasu adds a simple guard against multiple includes of the i40e_txrx.h file. Shannon provides a couple of fixes, first fix swaps a couple of lines around in the error handling if the allocation for the VSI array fails. Second fixes an issue where we try to free the q_vector that has not been setup which can panic the kernel. David provides a patch to save off the point to memory and the length of 2 structs used in the admin queue in order to store all info about allocated kernel memory. Neerav fixes ring allocation where allocation and clearing of rings for a VSI should be using the alloc_queue_pairs and not num_queue_pairs. Then removes the unused define for multi-queue enabled. ==================== Signed-off-by: -

netdev_kobject_init() is only being called from __init context, that is, net_dev_init(), so annotate it with __init as well, thus the kernel can take this as a hint that the function is used only during the initialization phase and free up used memory resources after its invocation. Signed-off-by:

Pablo Neira Ayuso says: ==================== netfilter/IPVS updates for net-next The following patchset contains Netfilter updates for your net-next tree, they are: * Add full port randomization support. Some crazy researchers found a way to reconstruct the secure ephemeral ports that are allocated in random mode by sending off-path bursts of UDP packets to overrun the socket buffer of the DNS resolver to trigger retransmissions, then if the timing for the DNS resolution done by a client is larger than usual, then they conclude that the port that received the burst of UDP packets is the one that was opened. It seems a bit aggressive method to me but it seems to work for them. As a result, Daniel Borkmann and Hannes Frederic Sowa came up with a new NAT mode to fully randomize ports using prandom. * Add a new classifier to x_tables based on the socket net_cls set via cgroups. These includes two patches to prepare the field as requested by Zefan Li. Also from Daniel Borkmann. * Use prandom instead of get_random_bytes in several locations of the netfilter code, from Florian Westphal. * Allow to use the CTA_MARK_MASK in ctnetlink when mangling the conntrack mark, also from Florian Westphal. * Fix compilation warning due to unused variable in IPVS, from Geert Uytterhoeven. * Add support for UID/GID via nfnetlink_queue, from Valentina Giusti. * Add IPComp extension to x_tables, from Fan Du. ==================== Signed-off-by:

The allocation and clearing of rings for a VSI should be using the alloc_queue_pairs and not num_queue_pairs. The alloc_queue_pairs per VSI is a pre-allocated number of queues assigned to a VSI; based on number of TCs enabled only certain number of queues may be used from that. This is mainly valid only for the LAN VSI case as that is the only VSI that may be enabled with multiple traffic classes. In the future the number of TCs may change based on DCBX configuration. The actual number of queues that are enabled/configured is based on the number of TCs enabled for a given VSI and that is stored in num_queue_pairs. With this change num_[tr]x_queues is unused so remove them. Change-Id: I9c2f84778bb25f7313c630e9b002a0caa883ce29 Signed-off-by:

Swap a couple lines around in the error handling if the kzalloc() for the pf->vsi array fails. This was causing a kernel BUG because the call to i40e_clear_interrupt_scheme() was assuming the pf->vsi[] array existed. In this fix it is possible that i40e_reset_interrupt_capability() will get called twice, but this is a safe action. Change-Id: I939163ccaa89baac7511556d36bc873864c35ae1 Signed-off-by:

When disabling and enabling VFs on a live system with the VF driver loaded, it's possible to receive an admin queue message from the VF driver at an inconvenient time, e.g. when the associated data structures aren't present or configured. This causes a rather inconvenient panic. To guard against this, we change the order of when we set num_alloc_vfs when turning off SR-IOV, and then gate processing of any VF messages based upon that value. Likewise, when enabling VFs, we shut off the relevant interrupt until configuration is complete. Change-Id: I0c172c056616c2bebd78bbc807ab446eb484deea Signed-off-by:
