Merge branch 'Control-action-percpu-counters-allocation-by-netlink-flag'
Vlad Buslov says: ==================== Control action percpu counters allocation by netlink flag Currently, significant fraction of CPU time during TC filter allocation is spent in percpu allocator. Moreover, percpu allocator is protected with single global mutex which negates any potential to improve its performance by means of recent developments in TC filter update API that removed rtnl lock for some Qdiscs and classifiers. In order to significantly improve filter update rate and reduce memory usage we would like to allow users to skip percpu counters allocation for specific action if they don't expect high traffic rate hitting the action, which is a reasonable expectation for hardware-offloaded setup. In that case any potential gains to software fast-path performance gained by usage of percpu-allocated counters compared to regular integer counters protected by spinlock are not important, but amount of additional CPU and memory consumed by them is significant. In order to allow configuring action counters allocation type at runtime, implement following changes: - Implement helper functions to update the action counters and use them in affected actions instead of updating counters directly. This steps abstracts actions implementation from counter types that are being used for particular action instance at runtime. - Modify the new helpers to use percpu counters if they were allocated during action initialization and use regular counters otherwise. - Extend action UAPI TCA_ACT space with TCA_ACT_FLAGS field. Add TCA_ACT_FLAGS_NO_PERCPU_STATS action flag and update hardware-offloaded actions to not allocate percpu counters when the flag is set. With this changes users that prefer action update slow-path speed over software fast-path speed can dynamically request actions to skip percpu counters allocation without affecting other users. Now, lets look at actual performance gains provided by this change. Simple test is used to measure insertion rate - iproute2 TC is executed in parallel by xargs in batch mode, its total execution time is measured by shell builtin "time" command. The command runs 20 concurrent tc instances, each with its own batch file with 100k rules: $ time ls add* | xargs -n 1 -P 20 sudo tc -b Two main rule profiles are tested. First is simple L2 flower classifier with single gact drop action. The configuration is chosen as worst case scenario because with single-action rules pressure on percpu allocator is minimized. Example rule: filter add dev ens1f0 protocol ip ingress prio 1 handle 1 flower skip_hw src_mac e4:11:0:0:0:0 dst_mac e4:12:0:0:0:0 action drop Second profile is typical real-world scenario that uses flower classifier with some L2-4 fields and two actions (tunnel_key+mirred). Example rule: filter add dev ens1f0_0 protocol ip ingress prio 1 handle 1 flower skip_hw src_mac e4:11:0:0:0:0 dst_mac e4:12:0:0:0:0 src_ip 192.168.111.1 dst_ip 192.168.111.2 ip_proto udp dst_port 1 src_port 1 action tunnel_key set id 1 src_ip 2.2.2.2 dst_ip 2.2.2.3 dst_port 4789 action mirred egress redirect dev vxlan1 Profile | percpu | no_percpu | X improvement | (k rules/sec) | (k rules/sec) | -------------------+---------------+---------------+--------------- Gact drop | 203 | 259 | 1.28 tunnel_key+mirred | 92 | 204 | 2.22 For simple drop action removing percpu allocation leads to ~25% insertion rate improvement.

Such rule profile scales much better than simple single action because both types of actions were competing for single lock in percpu allocator, but not for action idr lock, which is per-action. Note that percpu allocator is still used by dst_cache in tunnel_key actions and consumes 4.68% CPU time. Dst_cache seems like good opportunity for further insertion rate optimization but is not addressed by this change. Another improvement provided by this change is significantly reduced memory usage. The test is implemented by sampling "used memory" value from "vmstat -s" command output. Following table includes memory usage measurements for same two configurations that were used for measuring insertion rate: Profile | Mem per rule | Mem per rule no_percpu | Less memory used | (KB) | (KB) | (KB) -------------------+--------------+------------------------+------------------ Gact drop | 3.91 | 2.51 | 1.4 tunnel_key+mirred | 6.73 | 3.91 | 2.8 Results indicate that memory usage of percpu allocator per action is ~1.4 KB. Note that any measurements of percpu allocator memory usage is inherently tied to particular setup since memory usage is linear to number of cores in system. It is to be expected that on current top of the line servers percpu allocator memory usage will be 2-5x more than on 24 CPUs setup that was used for testing.
