description |
ct offload actions like add/del/stats are done in workqueue which can be bloat up in stress tests. can also cause active conns to age out.
one upstream commit to help with this is this
2ed37183abb7 netfilter: flowtable: separate replace, destroy and stats to different workqueues |
SRU Justification:
* Explain the bug(s)
Memory bloat and aging active ct conns can happen from any stress test as we have a single orkqueue for handling the ct offload conns for add/del/stats actions.
* brief explanation of fixes
The first patch (which is already upstream) splits the add, del, and stats work into separate work queues. The second patch limits the number of entries on the add work queue.
* How to test
Testing was done with just stress traffic with lots of conns different 5-tuple.
* What it could break.
Can take a lot of memory for a long time and also causing active conns to age out when not necessary.
