Hi all! Using QUEUE target I pretend mangle some type of packet(the first packets for each flow), but for modify each packet I need a lot of processing. If I make all in a single thread in some situation(burst of packet to mangle) the delay of packets might up. Then I think raise one thread for mangle each packet and in this thread call the function "ipq_set_verdict" with the new payload. I look and find "https://lists.netfilter.org/pipermail/netfilter/2003-October/047422.html"; Due to libipq isn't thread-safe I must copy the payload of each packet and pass it to the new thread in order to avoid rewrite it when arrive a new packet while I'm changing the previous packet payload. See http://www.experts-exchange.com/Programming/Programming_Platforms/Linux_Programming/Q_20766491.html My question is: Exist other precaution that I must take? Thank in advance Frank
