Johannes Berg	8cb081746c	netlink: make validation more configurable for future strictness ... We currently have two levels of strict validation: 1) liberal (default) - undefined (type >= max) & NLA_UNSPEC attributes accepted - attribute length >= expected accepted - garbage at end of message accepted 2) strict (opt-in) - NLA_UNSPEC attributes accepted - attribute length >= expected accepted Split out parsing strictness into four different options: * TRAILING - check that there's no trailing data after parsing attributes (in message or nested) * MAXTYPE - reject attrs > max known type * UNSPEC - reject attributes with NLA_UNSPEC policy entries * STRICT_ATTRS - strictly validate attribute size The default for future things should be *everything*. The current *_strict() is a combination of TRAILING and MAXTYPE, and is renamed to _deprecated_strict(). The current regular parsing has none of this, and is renamed to *_parse_deprecated(). Additionally it allows us to selectively set one of the new flags even on old policies. Notably, the UNSPEC flag could be useful in this case, since it can be arranged (by filling in the policy) to not be an incompatible userspace ABI change, but would then going forward prevent forgetting attribute entries.

Michal Kubecek	ae0be8de9a	netlink: make nla_nest_start() add NLA_F_NESTED flag ... Even if the NLA_F_NESTED flag was introduced more than 11 years ago, most netlink based interfaces (including recently added ones) are still not setting it in kernel generated messages. Without the flag, message parsers not aware of attribute semantics (e.g. wireshark dissector or libmnl's mnl_nlmsg_fprintf()) cannot recognize nested attributes and won't display the structure of their contents. Unfortunately we cannot just add the flag everywhere as there may be userspace applications which check nlattr::nla_type directly rather than through a helper masking out the flags. Therefore the patch renames nla_nest_start() to nla_nest_start_noflag() and introduces nla_nest_start() as a wrapper adding NLA_F_NESTED. The calls which add NLA_F_NESTED manually are rewritten to use nla_nest_start(). Except for changes in include/net/netlink.h, the patch was generated using this semantic patch: @@ expression E1, E2; @@ -nla_nest_start(E1, E2) +nla_nest_start_noflag(E1, E2) @@ expression E1, E2; @@ -nla_nest_start_noflag(E1, E2 | NLA_F_NESTED) +nla_nest_start(E1, E2) Signed-off-by: Michal Kubecek <mkubecek@suse.cz> Acked-by: Jiri Pirko <jiri@mellanox.com> Acked-by: David Ahern <dsahern@gmail.com> Signed-off-by: David S.

Numan Siddique	4d5ec89fc8	net: openvswitch: Add a new action check_pkt_len ... This patch adds a new action - 'check_pkt_len' which checks the packet length and executes a set of actions if the packet length is greater than the specified length or executes another set of actions if the packet length is lesser or equal to. This action takes below nlattrs * OVS_CHECK_PKT_LEN_ATTR_PKT_LEN - 'pkt_len' to check for * OVS_CHECK_PKT_LEN_ATTR_ACTIONS_IF_GREATER - Nested actions to apply if the packet length is greater than the specified 'pkt_len' * OVS_CHECK_PKT_LEN_ATTR_ACTIONS_IF_LESS_EQUAL - Nested actions to apply if the packet length is lesser or equal to the specified 'pkt_len'. The main use case for adding this action is to solve the packet drops because of MTU mismatch in OVN virtual networking solution. When a VM (which belongs to a logical switch of OVN) sends a packet destined to go via the gateway router and if the nic which provides external connectivity, has a lesser MTU, OVS drops the packet if the packet length is greater than this MTU. With the help of this action, OVN will check the packet length and if it is greater than the MTU size, it will generate an ICMP packet (type 3, code 4) and includes the next hop mtu in it so that the sender can fragment the packets.

If an OVS_ATTR_NESTED attribute type is found while walking through netlink attributes, we call nlattr_set() recursively passing the length table for the following nested attributes, if different from the current one. However, once we're done with those sub-nested attributes, we should continue walking through attributes using the current table, instead of using the one related to the sub-nested attributes. For example, given this sequence: 1 OVS_KEY_ATTR_PRIORITY 2 OVS_KEY_ATTR_TUNNEL 3 OVS_TUNNEL_KEY_ATTR_ID 4 OVS_TUNNEL_KEY_ATTR_IPV4_SRC 5 OVS_TUNNEL_KEY_ATTR_IPV4_DST 6 OVS_TUNNEL_KEY_ATTR_TTL 7 OVS_TUNNEL_KEY_ATTR_TP_SRC 8 OVS_TUNNEL_KEY_ATTR_TP_DST 9 OVS_KEY_ATTR_IN_PORT 10 OVS_KEY_ATTR_SKB_MARK 11 OVS_KEY_ATTR_MPLS we switch to the 'ovs_tunnel_key_lens' table on attribute #3, and we don't switch back to 'ovs_key_lens' while setting attributes #9 to #11 in the sequence.

zhangliping	67c8d22a73	openvswitch: fix the incorrect flow action alloc size ... If we want to add a datapath flow, which has more than 500 vxlan outputs' action, we will get the following error reports: openvswitch: netlink: Flow action size 32832 bytes exceeds max openvswitch: netlink: Flow action size 32832 bytes exceeds max openvswitch: netlink: Actions may not be safe on all matching packets ... ... It seems that we can simply enlarge the MAX_ACTIONS_BUFSIZE to fix it, but this is not the root cause. For example, for a vxlan output action, we need about 60 bytes for the nlattr, but after it is converted to the flow action, it only occupies 24 bytes. This means that we can still support more than 1000 vxlan output actions for a single datapath flow under the the current 32k max limitation. So even if the nla_len(attr) is larger than MAX_ACTIONS_BUFSIZE, we shouldn't report EINVAL and keep it move on, as the judgement can be done by the reserve_sfa_size.

Jakub Kicinski	3fcece12bc	net: store port/representator id in metadata_dst ... Switches and modern SR-IOV enabled NICs may multiplex traffic from Port representators and control messages over single set of hardware queues. Control messages and muxed traffic may need ordered delivery. Those requirements make it hard to comfortably use TC infrastructure today unless we have a way of attaching metadata to skbs at the upper device. Because single set of queues is used for many netdevs stopping TC/sched queues of all of them reliably is impossible and lower device has to retreat to returning NETDEV_TX_BUSY and usually has to take extra locks on the fastpath. This patch attempts to enable port/representative devs to attach metadata to skbs which carry port id. This way representatives can be queueless and all queuing can be performed at the lower netdev in the usual way. Traffic arriving on the port/representative interfaces will be have metadata attached and will subsequently be queued to the lower device for transmission. The lower device should recognize the metadata and translate it to HW specific format which is most likely either a special header inserted before the network headers or descriptor/metadata fields. Metadata is associated with the lower device by storing the netdev pointer along with port id so that if TC decides to redirect or mirror the new netdev will not try to interpret it. This is mostly for SR-IOV devices since switches don't have lower netdevs today.

andy zhou	798c166173	openvswitch: Optimize sample action for the clone use cases ... With the introduction of open flow 'clone' action, the OVS user space can now translate the 'clone' action into kernel datapath 'sample' action, with 100% probability, to ensure that the clone semantics, which is that the packet seen by the clone action is the same as the packet seen by the action after clone, is faithfully carried out in the datapath. While the sample action in the datpath has the matching semantics, its implementation is only optimized for its original use. Specifically, there are two limitation: First, there is a 3 level of nesting restriction, enforced at the flow downloading time. This limit turns out to be too restrictive for the 'clone' use case. Second, the implementation avoid recursive call only if the sample action list has a single userspace action. The main optimization implemented in this series removes the static nesting limit check, instead, implement the run time recursion limit check, and recursion avoidance similar to that of the 'recirc' action. This optimization solve both #1 and #2 issues above. One related optimization attempts to avoid copying flow key as long as the actions enclosed does not change the flow key. The detection is performed only once at the flow downloading time. Another related optimization is to rewrite the action list at flow downloading time in order to save the fast path from parsing the sample action list in its original form repeatedly.

Jarno Rajahalme	9dd7f8907c	openvswitch: Add original direction conntrack tuple to sw_flow_key. ... Add the fields of the conntrack original direction 5-tuple to struct sw_flow_key. The new fields are initially marked as non-existent, and are populated whenever a conntrack action is executed and either finds or generates a conntrack entry. This means that these fields exist for all packets that were not rejected by conntrack as untrackable. The original tuple fields in the sw_flow_key are filled from the original direction tuple of the conntrack entry relating to the current packet, or from the original direction tuple of the master conntrack entry, if the current conntrack entry has a master. Generally, expected connections of connections having an assigned helper (e.g., FTP), have a master conntrack entry. The main purpose of the new conntrack original tuple fields is to allow matching on them for policy decision purposes, with the premise that the admissibility of tracked connections reply packets (as well as original direction packets), and both direction packets of any related connections may be based on ACL rules applying to the master connection's original direction 5-tuple. This also makes it easier to make policy decisions when the actual packet headers might have been transformed by NAT, as the original direction 5-tuple represents the packet headers before any such transformation. When using the original direction 5-tuple the admissibility of return and/or related packets need not be based on the mere existence of a conntrack entry, allowing separation of admission policy from the established conntrack state. While existence of a conntrack entry is required for admission of the return or related packets, policy changes can render connections that were initially admitted to be rejected or dropped afterwards. If the admission of the return and related packets was based on mere conntrack state (e.g., connection being in an established state), a policy change that would make the connection rejected or dropped would need to find and delete all conntrack entries affected by such a change. When using the original direction 5-tuple matching the affected conntrack entries can be allowed to time out instead, as the established state of the connection would not need to be the basis for packet admission any more. It should be noted that the directionality of related connections may be the same or different than that of the master connection, and neither the original direction 5-tuple nor the conntrack state bits carry this information. If needed, the directionality of the master connection can be stored in master's conntrack mark or labels, which are automatically inherited by the expected related connections. The fact that neither ARP nor ND packets are trackable by conntrack allows mutual exclusion between ARP/ND and the new conntrack original tuple fields. Hence, the IP addresses are overlaid in union with ARP and ND fields. This allows the sw_flow_key to not grow much due to this patch, but it also means that we must be careful to never use the new key fields with ARP or ND packets. ARP is easy to distinguish and keep mutually exclusive based on the ethernet type, but ND being an ICMPv6 protocol requires a bit more attention.

Jiri Benc	329f45bc4f	openvswitch: add mac_proto field to the flow key ... Use a hole in the structure. We support only Ethernet so far and will add a support for L2-less packets shortly. We could use a bool to indicate whether the Ethernet header is present or not but the approach with the mac_proto field is more generic and occupies the same number of bytes in the struct, while allowing later extensibility. It also makes the code in the next patches more self explaining. It would be nice to use ARPHRD_ constants but those are u16 which would be waste. Thus define our own constants. Another upside of this is that we can overload this new field to also denote whether the flow key is valid. This has the advantage that on refragmentation, we don't have to reparse the packet but can rely on the stored eth.type. This is especially important for the next patches in this series - instead of adding another branch for L2-less packets before calling ovs_fragment, we can just remove all those branches completely.

Simon Horman	fe3a5f6c79	openvswitch: allow output of MPLS packets on tunnel vports ... Currently output of MPLS packets on tunnel vports is not allowed by Open vSwitch. This is because historically encapsulation was done in such a way that the inner_protocol field of the skb needed to hold the inner protocol for both MPLS and tunnel encapsulation in order for GSO segmentation to be performed correctly. Since b2acd1dc39 ("openvswitch: Use regular GRE net_device instead of vport") Open vSwitch makes use of lwt to output to tunnel netdevs which perform encapsulation. As no drivers expose support for MPLS offloads this means that GSO packets are segmented in software by validate_xmit_skb(), which is called from __dev_queue_xmit(), before tunnel encapsulation occurs. This means that the inner protocol of MPLS is no longer needed by the time encapsulation occurs and the contention on the inner_protocol field of the skb no longer occurs. Thus it is now safe to output MPLS to tunnel vports. Signed-off-by: Simon Horman <simon.horman@netronome.com> Reviewed-by: Jesse Gross <jesse@kernel.org> Signed-off-by: David S.
