With struct flow_dissector_key_mpls now recording the first FLOW_DIS_MPLS_MAX labels, we can extend Flower to filter on any of these LSEs independently. In order to avoid creating new netlink attributes for every possible depth, let's define a new TCA_FLOWER_KEY_MPLS_OPTS nested attribute that contains the list of LSEs to match. Each LSE is represented by another attribute, TCA_FLOWER_KEY_MPLS_OPTS_LSE, which then contains the attributes representing the depth and the MPLS fields to match at this depth (label, TTL, etc.). For each MPLS field, the mask is always set to all-ones, as this is what the original API did. We could allow user configurable masks in the future if there is demand for more flexibility. The new API also allows to only specify an LSE depth. In that case, Flower only verifies that the MPLS label stack depth is greater or equal to the provided depth (that is, an LSE exists at this depth). Filters that only match on one (or more) fields of the first LSE are dumped using the old netlink attributes, to avoid confusing user space programs that don't understand the new API. Signed-off-by:

The current MPLS dissector only parses the first MPLS Label Stack Entry (second LSE can be parsed too, but only to set a key_id). This patch adds the possibility to parse several LSEs by making __skb_flow_dissect_mpls() return FLOW_DISSECT_RET_PROTO_AGAIN as long as the Bottom Of Stack bit hasn't been seen, up to a maximum of FLOW_DIS_MPLS_MAX entries. FLOW_DIS_MPLS_MAX is arbitrarily set to 7. This should be enough for many practical purposes, without wasting too much space. To record the parsed values, flow_dissector_key_mpls is modified to store an array of stack entries, instead of just the values of the first one. A bit field, "used_lses", is also added to keep track of the LSEs that have been set. The objective is to avoid defining a new FLOW_DISSECTOR_KEY_MPLS_XX for each level of the MPLS stack. TC flower is adapted for the new struct flow_dissector_key_mpls layout. Matching on several MPLS Label Stack Entries will be added in the next patch. The NFP and MLX5 drivers are also adapted: nfp_flower_compile_mac() and mlx5's parse_tunnel() now verify that the rule only uses the first LSE and fail if it doesn't. Finally, the behaviour of the FLOW_DISSECTOR_KEY_MPLS_ENTROPY key is slightly modified. Instead of recording the first Entropy Label, it now records the last one. This shouldn't have any consequences since there doesn't seem to have any user of FLOW_DISSECTOR_KEY_MPLS_ENTROPY in the tree. We'd probably better do a hash of all parsed MPLS labels instead (excluding reserved labels) anyway. That'd give better entropy and would probably also simplify the code. But that's not the purpose of this patch, so I'm keeping that as a future possible improvement. Signed-off-by:

Tuong Lien says: ==================== tipc: add some improvements This series adds some improvements to TIPC. The first patch improves the TIPC broadcast's performance with the 'Gap ACK blocks' mechanism similar to unicast before, while the others give support on tracing & statistics for broadcast links, and an alternative to carry broadcast retransmissions via unicast which might be useful in some cases. Besides, the Nagle algorithm can now automatically 'adjust' itself depending on the specific network condition a stream connection runs by the last patch. ==================== Signed-off-by: -
Tuong Lien authored
When streaming in Nagle mode, we try to bundle small messages from user as many as possible if there is one outstanding buffer, i.e. not ACK-ed by the receiving side, which helps boost up the overall throughput. So, the algorithm's effectiveness really depends on when Nagle ACK comes or what the specific network latency (RTT) is, compared to the user's message sending rate. In a bad case, the user's sending rate is low or the network latency is small, there will not be many bundles, so making a Nagle ACK or waiting for it is not meaningful. For example: a user sends its messages every 100ms and the RTT is 50ms, then for each messages, we require one Nagle ACK but then there is only one user message sent without any bundles. In a better case, even if we have a few bundles (e.g. the RTT = 300ms), but now the user sends messages in medium size, then there will not be any difference at all, that says 3 x 1000-byte data messages if bundled will still result in 3 bundles with MTU = 1500. When Nagle is ineffective, the delay in user message sending is clearly wasted instead of sending directly. Besides, adding Nagle ACKs will consume some processor load on both the sending and receiving sides. This commit adds a test on the effectiveness of the Nagle algorithm for an individual connection in the network on which it actually runs. Particularly, upon receipt of a Nagle ACK we will compare the number of bundles in the backlog queue to the number of user messages which would be sent directly without Nagle. If the ratio is good (e.g. >= 2), Nagle mode will be kept for further message sending. Otherwise, we will leave Nagle and put a 'penalty' on the connection, so it will have to spend more 'one-way' messages before being able to re-enter Nagle. In addition, the 'ack-required' bit is only set when really needed that the number of Nagle ACKs will be reduced during Nagle mode. Testing with benchmark showed that with the patch, there was not much difference in throughput for small messages since the tool continuously sends messages without a break, so Nagle would still take in effect.

This commit enables dumping the statistics of a broadcast-receiver link like the traditional 'broadcast-link' one (which is for broadcast- sender). The link dumping can be triggered via netlink (e.g. the iproute2/tipc tool) by the link flag - 'TIPC_NLA_LINK_BROADCAST' as the indicator. The name of a broadcast-receiver link of a specific peer will be in the format: 'broadcast-link:<peer-id>'. For example: Link <broadcast-link:1001002> Window:50 packets RX packets:7841 fragments:2408/440 bundles:0/0 TX packets:0 fragments:0/0 bundles:0/0 RX naks:0 defs:124 dups:0 TX naks:21 acks:0 retrans:0 Congestion link:0 Send queue max:0 avg:0 In addition, the broadcast-receiver link statistics can be reset in the usual way via netlink by specifying that link name in command. Note: the 'tipc_link_name_ext()' is removed because the link name can now be retrieved simply via the 'l->name'. Acked-by:

In some environment, broadcast traffic is suppressed at high rate (i.e. a kind of bandwidth limit setting). When it is applied, TIPC broadcast can still run successfully. However, when it comes to a high load, some packets will be dropped first and TIPC tries to retransmit them but the packet retransmission is intentionally broadcast too, so making things worse and not helpful at all. This commit enables the broadcast retransmission via unicast which only retransmits packets to the specific peer that has really reported a gap i.e. not broadcasting to all nodes in the cluster, so will prevent from being suppressed, and also reduce some overheads on the other peers due to duplicates, finally improve the overall TIPC broadcast performance. Note: the functionality can be turned on/off via the sysctl file: echo 1 > /proc/sys/net/tipc/bc_retruni echo 0 > /proc/sys/net/tipc/bc_retruni Default is '0', i.e. the broadcast retransmission still works as usual.

Tuong Lien authored
As achieved through commit 9195948f ("tipc: improve TIPC throughput by Gap ACK blocks"), we apply the same mechanism for the broadcast link as well. The 'Gap ACK blocks' data field in a 'PROTOCOL/STATE_MSG' will consist of two parts built for both the broadcast and unicast types: 31 16 15 0 +-------------+-------------+-------------+-------------+ | bgack_cnt | ugack_cnt | len | +-------------+-------------+-------------+-------------+ - | gap | ack | | +-------------+-------------+-------------+-------------+ > bc gacks : : : | +-------------+-------------+-------------+-------------+ - | gap | ack | | +-------------+-------------+-------------+-------------+ > uc gacks : : : | +-------------+-------------+-------------+-------------+ - which is "automatically" backward-compatible. We also increase the max number of Gap ACK blocks to 128, allowing upto 64 blocks per type (total buffer size = 516 bytes). Besides, the 'tipc_link_advance_transmq()' function is refactored which is applicable for both the unicast and broadcast cases now, so some old functions can be removed and the code is optimized. With the patch, TIPC broadcast is more robust regardless of packet loss or disorder, latency, ... in the underlying network. Its performance is boost up significantly. For example, experiment with a 5% packet loss rate results: $ time tipc-pipe --mc --rdm --data_size 123 --data_num 1500000 real 0m 42.46s user 0m 1.16s sys 0m 17.67s Without the patch: $ time tipc-pipe --mc --rdm --data_size 123 --data_num 1500000 real 8m 27.94s user 0m 0.55s sys 0m 2.38s Acked-by:

The commit 8c46fcd7 ("batman-adv: disable ethtool link speed detection when auto negotiation off") disabled the usage of ethtool's link_ksetting when auto negotation was enabled due to invalid values when used with tun/tap virtual net_devices. According to the patch, automatic measurements should be used for these kind of interfaces. But there are major flaws with this argumentation: * automatic measurements are not implemented * auto negotiation has nothing to do with the validity of the retrieved values The first point has to be fixed by a longer patch series. The "validity" part of the second point must be addressed in the same patch series by dropping the usage of ethtool's link_ksetting (thus always doing automatic measurements over ethernet). Drop the patch again to have more default values for various net_device types/configurations. The user can still overwrite them using the batadv_hardif's BATADV_ATTR_THROUGHPUT_OVERRIDE. Reported-by:

The issue was reported by syzbot. When the function br_mrp_parse was called with a valid net_bridge_port, the net_bridge was an invalid pointer. Therefore the check br->stp_enabled could pass/fail depending where it was pointing in memory. The fix consists of setting the net_bridge pointer if the port is a valid pointer.

As explained in commit 9ffcc372 ("mlxsw: spectrum: Allow packets to be trapped from any PG"), incoming packets can be admitted to the shared buffer and forwarded / trapped, if: (Ingress{Port}.Usage < Thres && Ingress{Port,PG}.Usage < Thres && Egress{Port}.Usage < Thres && Egress{Port,TC}.Usage < Thres) || (Ingress{Port}.Usage < Min || Ingress{Port,PG} < Min || Egress{Port}.Usage < Min || Egress{Port,TC}.Usage < Min) Trapped packets are scheduled to transmission through the CPU port. Currently, the minimum and maximum quotas of traffic class (TC) 0 of the CPU port are 0, which means it is not usable. Assign non-zero quotas to TC 0 of the CPU port, so that it could be utilized by subsequent patches. Signed-off-by:
