2020-04-30netlink: extend policy range validationJohannes Berg2-21/+137
Using a pointer to a struct indicating the min/max values, extend the ability to do range validation for arbitrary values. Small values in the s16 range can be kept in the policy directly. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2020-04-30nl80211: link recursive netlink nested policyJohannes Berg3-10/+5
Now that we have limited recursive policy validation to avoid stack overflows, change nl80211 to actually link the nested policy (linking back to itself eventually), which allows some code cleanups.

2020-04-30netlink: limit recursion depth in policy validationJohannes Berg1-12/+34
Now that we have nested policies, we can theoretically recurse forever parsing attributes if a (sub-)policy refers back to a higher level one. This is a situation that has happened in nl80211, and we've avoided it there by not linking it. Add some code to netlink parsing to limit recursion depth.

2020-04-30netlink: remove type-unsafe validation_data pointerJohannes Berg4-53/+49
In the netlink policy, we currently have a void *validation_data that's pointing to different things: * a u32 value for bitfield32, * the netlink policy for nested/nested array * the string for NLA_REJECT Remove the pointer and place appropriate type-safe items in the union instead.

Currently, tcp_sack_new_ofo_skb() sends an ack if prior acks were 'compressed', if room has to be made in tp->selective_acks[] But there is no guarantee all four sack ranges can be included in SACK option. As a matter of fact, when TCP timestamps option is used, only three SACK ranges can be included. Lets assume only two ranges can be included, and force the ack: - When we touch more than 2 ranges in the reordering done if tcp_sack_extend() could be done. - If we have at least 2 ranges when adding a new one. This enforces that before a range is in third or fourth position, at least one ACK packet included it in first/second position.

2020-04-30tcp: add tp->dup_ack_counterEric Dumazet4-13/+38
In commit 86de5921a3d5 ("tcp: defer SACK compression after DupThresh") I added a TCP_FASTRETRANS_THRESH bias to tp->compressed_ack in order to enable sack compression only after 3 dupacks. Since we plan to relax this rule for flows that involve stacks not requiring this old rule, this patch adds a distinct tp->dup_ack_counter. This means the TCP_FASTRETRANS_THRESH value is now used in a single location that a future patch can adjust: if (tp->dup_ack_counter < TCP_FASTRETRANS_THRESH) { tp->dup_ack_counter++; goto send_now; } This patch also introduces tcp_sack_compress_send_ack() helper to ease following patch comprehension. This patch refines LINUX_MIB_TCPACKCOMPRESSED to not count the acks that we had to send if the timer expires or tcp_sack_compress_send_ack() is sending an ack.

2020-04-30Merge branch 'mlxsw-Prepare-SPAN-API-for-upcoming-changes'David S. Miller4-244/+449
Ido Schimmel says: ==================== mlxsw: Prepare SPAN API for upcoming changes Switched port analyzer (SPAN) is used for packet mirroring. Over mlxsw this is achieved by attaching tc-mirred action to either matchall or flower classifier. The current API used to configure SPAN consists of two functions: mlxsw_sp_span_mirror_add() and mlxsw_sp_span_mirror_del(). These two functions pack a lot of different operations: * SPAN agent configuration: Determining the egress port and optional headers that need to encapsulate the mirrored packet (when mirroring to a gretap, for example) * Egress mirror buffer configuration: Allocating / freeing a buffer when port is analyzed (inspected) at egress * SPAN agent binding: Binding the SPAN agent to a trigger, if any. The current triggers are incoming / outgoing packet and they are only used for matchall-based mirroring This non-modular design makes it difficult to extend the API for future changes, such as new mirror targets (CPU) and new global triggers (early dropped packets, for example). Therefore, this patch set gradually adds APIs for above mentioned operations and then converts the two existing users to use it instead of the old API. No functional changes intended. Tested with existing mirroring selftests.

2020-04-30mlxsw: spectrum_span: Use new analyzed ports list during speed / MTU changeIdo Schimmel1-37/+35
As previously explained, each port whose outgoing traffic is analyzed needs to have an egress mirror buffer. The size of the egress mirror buffer is calculated based on various parameters, two of which are the speed and the MTU of the port. Therefore, when the MTU or the speed of a port change, the SPAN code is called to see if the egress mirror buffer of the port needs to be adjusted. Currently, this is done by traversing all the SPAN agents and for each SPAN agent the list of bound ports is traversed. Instead of the above, traverse the recently added list of analyzed ports. This will later allow us to remove the old SPAN API. Signed-off-by: Ido Schimmel <idosch@mellanox.com> Reviewed-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2020-04-30mlxsw: spectrum_span: Add APIs to bind / unbind a SPAN agentIdo Schimmel2-0/+187
Currently, a SPAN agent can only be bound to a per-port trigger where the trigger is either an incoming packet (INGRESS) or an outgoing packet (EGRESS) to / from the port. A follow-up patch set will introduce the concept of global triggers and per-{port, TC} enablement. With global triggers, the trigger entry is only keyed by a trigger and not by a port and a trigger. The trigger can be, for example, a packet that was early dropped. While the binding between the SPAN agent and the trigger is performed only once, the trigger entry needs to be reference counted, as the trigger can be enabled on multiple ports. Add APIs to bind / unbind a SPAN agent to a trigger and reference count the trigger entry in preparation for global triggers.

2020-04-30mlxsw: spectrum_span: Add APIs to get / put an analyzed portIdo Schimmel2-0/+140
An analyzed port is a port whose incoming / outgoing traffic is mirrored to a SPAN agent and analyzed on a remote server. A port can be analyzed by multiple tc filters and therefore the corresponding analyzed port entry needs to be reference counted. This is significant because ports whose outgoing traffic is analyzed need to have an egress mirror buffer. Add APIs to get / put an analyzed port. Allocate an egress mirror buffer on a port when it is first inspected at egress and free the buffer when it is no longer inspected at egress. Protect the list of analyzed ports with a mutex, as a later patch will traverse it from a context in which RTNL lock is not held.
