  1. С несколькими потоками да, байда какая-то. Я так и не отловил... При num_threads=1 проблем никаких не наблюдаю. 4.7/4.9 ядра...
  2. Для начала можно попробовать "num_threads = 1" в nfqfilter.ini.
  3. Имхо, на скоростях от пары мегабит - уже особой разницы нет. Всё может быть. Тот же ipt_NETFLOW пока не забросил, надеюсь и ratelimit не забросит ) По-моему, "официальная" позиция ядрописателей примерно такая - "файрвол - файрволит, а классами трафика и прочими ограничениями скоростей занимается tc и нечего тёплое с мягким смешивать".
  4. Нет такой проблемы. 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt20-1+deb8u3 (2016-01-17) x86_64 GNU/Linux modinfo xt_ratelimit filename: /lib/modules/3.16.0-4-amd64/extra/xt_ratelimit.ko alias: ipt_ratelimit version: 0.2-7-gab96c49 license: GPL description: iptables ratelimit policer mt module author: <abc@telekom.ru> srcversion: 1035E6107F174D31E1EBA6B depends: x_tables vermagic: 3.16.0-4-amd64 SMP mod_unload modversions parm: hashsize:default size of hash table used to look up IPs (uint) Вы случайно ядро не обновляли без последующей перезагрузки?
  5. А какие изменения в код вносили??? Тоже интересно, только в режиме полисер Возьмите уже ipt_ratelimit. Обвязка за 15 минут пишется....
  6. Какая-то непонятная бага ядра обнаружилась - периодически (раз в 1-3 часа) уходит в kernel panic при num_threads > 1. Без nfqfilter, либо с num_threads = 1 падений нет... На 4.2 и 4.7 проявлялось на НЕКОТОРЫХ машинах. У нас десяток плюс минус одинаковых (с точки зрения настроек, железо - разное) машин, падает на 2-х, закономерность выявить не удалось. Чё-то фантазии не хватает в какую сторону копать: Dec 19 18:49:51 nat-serv [ 3396.252741] ------------[ cut here ]------------ Dec 19 18:49:51 nat-serv [ 3396.252766] kernel BUG at /home/zumbi/linux-4.2.3/net/netfilter/nf_nat_core.c:391!

  7. Так вы не стесняйтесь, спросите у автора - возможна ли такая доработка и сколько она будет стоить :))

  9. А, ну так-то да. Я думал может в "развесистом" варианте нашлось какое-то применение :) Спасибо всё равно :)
