similar to: centos 7.5 crashed, kernel BUG at net/core/skbuff.c:3668!

This patch updates the network emulation packet scheduler. * name changed from delay to netem since it does more than just delay * Catalin''s merged code to do packet reordering * uses a socket queue''s directly rather than layering on qdisc(fifo) because this is used in performance tests. * adds placeholder in API for future enhancements (rate and duplicate).

I want to take the functionality that I found sitting in linux-2.6.8-rc2/net/sched/sch_netem.c for a test drive but I found that the /sbin/tc that I have does not have the necessary knobs. So I grabbed iproute2-2.6.X-ss040702.tar.gz and tried to build it, but I got this: q_netem.c: In function `netem_parse_opt'': q_netem.c:90: error: structure has no member named `rate''

Hi all I have a trouble configuring the qdiscs, when I indicate the "perturb 10" option to tc, i gives me this error: tc qdisc add dev eth0 parent 5:1323 handle 1323 sfq perturb 10 RTNETLINK answers: Invalid argument if I don''t put the "perturb 10" option, it works. another question is about iptables, when I indicate the " --set-mark" option: iptables -t

Hi Herbert, I wonder if you''ve got a chance to look at netfront in light of the new stuff in davem''s network tree (the stuff that''s in http://git.kernel.org/?p=linux/kernel/git/davem/net-2.6.22.git). In particular, struct sk_buff has been changed so that "nh" has gone, and the replacement can be just an offset rather than a full pointer. This breaks the

hi i tried the example given on the examples page to duplicate selected traffic like tc qdisc add dev eth0 root handle 1: prio tc qdisc add dev eth0 parent 1:3 handle 3: netem duplicate 40% tc filter add dev eth0 protocol ip parent 1:0 prio 3 u32 match ip dst 11.0.2.2 flowid 1:3 when i ping from 11.0.2.2 to this interface my machine hangs. the same thing works for drop or delay. i would

Hi, I am using netem to add loss and then adding another qdisc within netem according to the wiki. Then i want to change the netem drop probability without having to delete the qdisc and recreate it. I try it but I get invalid argument: thorium-ini hedpe # tc qdisc add dev ath0 root handle 1:0 netem drop 1% thorium-ini hedpe # tc qdisc add dev ath0 parent 1:1 handle 10: xcp capacity 54Mbit

Hello all, I am trying to match some conections using u32 but I tryed this: [root@ns1 ~]# tc filter add dev eth1 parent 1:0 protocol ip prio 1 u32 match ip src 0/0 match ip dst 0/0 match ip sport 80 0xffff flowid 1:10 RTNETLINK answers: Invalid argument We have an error talking to the kernel [root@ns1 ~]# I have this class at device eth1: [root@ns1 ~]# tc class show dev eth1 class
