Error with kernel-4.8.0 and 4.8.1 #45

Closed costel78 closed 8 years ago

costel78 commented 8 years ago

Patch for kernel 4.8 seems to be incomplete:

ERROR: "validate_xmit_skb_list" [drivers/net/imq.ko] undefined!
ERROR: "dev_hard_start_xmit" [drivers/net/imq.ko] undefined!
make[1]: *** [scripts/Makefile.modpost:91: __modpost] Error 1
make: *** [Makefile:1180: modules] Error 2

Both functions are defined in netdevice.h and implemented in net/core/dev.c, but they are not visible. I had to add EXPORT_SYMBOL(validate_xmit_skb_list); and EXPORT_SYMBOL(dev_hard_start_xmit);in dev.c

Well, my c/c++ knowlegde are basics, kernel experience - a big zero. I just compared versions from 4.6 to 4.8 and dig on internet to understand notions new to me, so please advise me. The kernel is compiled, both bzImage and all modules, but it is safe ?

k0ste commented 8 years ago

@costel78, please try this patch #46.

costel78 commented 8 years ago

The patch apply clean, no error during compile, but I got kernel panic as I load imq module. I tried to compile it as build-in. As soon as I redirect something to imq0 kernel crash instantly.

k0ste commented 8 years ago

I think you overtuned your kernel. I test patches before push.

selection_003

iperf3

selection_004

k0ste commented 8 years ago

I can reproduce. Kernel panic if add qdisc to imq interface, like htb+sfq. And set imq interface up.

costel78 commented 8 years ago

Not really overtuning, but I also use account and ipmark from xtables-addons. I tested with vanilla kernel and nothing else, with same result. At first, I really believed it is xtables-addons or something from gentoo-patches. Yes, same setup here, PPPoE and ethernet interfaces directed to imq[0-3] interfaces and htb+sfq used to traffic shaping. Please, forgive my English.

Thank you very much for your support. I really appreciate.

k0ste commented 8 years ago

IMQ is a community maintained project. Please attach your crash dump, and we can summon Gao, to look at patch and fix the problem.

costel78 commented 8 years ago

I am unable to reproduce it on my own pc (a single net interface) and won't have physically access to server until tomorrow. I'll post a picture of crash dump as soon as possible.

Sorry for quality.

gfreewind commented 8 years ago

Could you paste the core dump with text format ?

costel78 commented 8 years ago

I am sorry but first, I don't know exactly how to do that (as I remember I'll need kexec) and, second, server downtime became a issue. It is not mine, I helped a friend to switch from mac/ip to pppoe, therefor the need for imq. The main idea is the server is in production, around 150 customers. I see two solutions:

  1. familiarize myself with kexec (or whatever is necessary) and try to do the tests early in the morning to not perturb their clients to much, if they will agree with the plan.
  2. maybe provide me some hints to trigger the error on my own computer. Only one ethernet interface here.

Thank you!

With this patch #46 I have no further kernel crashs. Would my .config help here to see the differences ?

micron10 commented 8 years ago

no no need my config is too clean and i have : pppoe , ppptp, static ip, dhcp , and other serivces. This dump is from one of other machine with more serivces and its ok for debug only on this 3 machine i have error new patch is installed on 5 machine 2 work fine without error (pppoe,and static)

3 work no fine and need to back to kernel 4.7.8 (with pppoe,pptp,static dhcp and other ) and dump is from there.
