I didn't verify this too much, so I might be wrong, but it looks like
cls_cgroup_classify() does things a bit different than others (doesn't
check the 'head' etc. for NULL), so maybe you should consider fixing
it instead? (Btw., the tc classifier maintainer added to Cc).

Re: [BUG] net_cls: Panic occured when net_cls subsystem use

Hi there,

Sorry - cant help you on earlier question in the thread on
syntax of cls_group config (but we can revisit after resolving
this). You should always copy the maintainer if you want quick
answers (for cls_group case Thomas Graf).

On your patch:
I think you have found a real issue (I have a strong feeling
it has everything to do with your config process)

This is incorrect. tp may already exist and you dont want to destroy
for failure to change its parameters. You also dont want to reattach
an existing tp because it succeeded in parameter change. 
So the soln is to check if this is a new tp and then do what you did
above...
Did that make sense?

OOPS! Others mostly don't check this either, so my suggestion was wrong.

Hmm... Or maybe I wasn't so wrong; it seems classifiers which
don't assign the head during init do this check for NULL later.

It is good practise to initialize things in init() and use attributes
in change() to set them. 
I will read the thread and check out the code path then respond
more intelligently.

                switch (n->nlmsg_type) {
                case RTM_NEWTFILTER:

Probably this case needs tcf_destroy() too.

Since "tc filter replace" uses this type and flag too without creating
tp, this check is not enough. I guess we could simply use a variable
like tp_created etc. Anyway, changing this place looks tricky to me,
so maybe it would be safer to do a separate cls_cgroup fix just for
-stable, and this one patch for -next only?

It will be superfluos. 
tp_created is the check
n->nlmsg_type == RTM_NEWTFILTER && n->nlmsg_flags&NLM_F_CREATE
replace will be
n->nlmsg_type == RTM_NEWTFILTER && n->nlmsg_flags & NLM_F_EXCL

I think they are two separate issues.
The fact that we dont destroy an allocated tp on failure is an issue
regardless of what cls_group does. In the case of Minoru's issue
it is because he is misconfiguring cls_group.

Hmm... Probably I miss something, but I've just seen this prink during
tc filter replace with:

err = tp->ops->change();
if (n->nlmsg_type == RTM_NEWTFILTER && (n->nlmsg_flags&NLM_F_CREATE))
	printk(...);

Sure, but we don't want people to get oops in such a case, I guess.

That sounds right. 
Remeber, you could have NLM_F_EXCL|NLM_F_CREATE to indicate "create this
thing if it doesnt exist; if it exists  it is an error"
If it doesnt exist we will enter that (tp == NULL) path
also fh will be 0 ==> So you will never enter the code
path you are refering to.
If it exists (i.e you found it) and you enter the code path you refer
to, then you surely dont want to destroy it if NLM_F_EXCL is set.

I mean we don't want to link it again or destroy after ->change() err
if we run replace (n->nlmsg_type == RTM_NEWTFILTER &&
(n->nlmsg_flags&NLM_F_CREATE)).

IMHO it could be fixed "old way" in cls_group code too.

excellent point: an additional flag is needed then
n->nlmsg_flags& (NLM_F_CREATE|NLM_F_EXCL).
Minoru, please add this change in the patch before testing...

Is the code oopsing in cls_group? It didnt seem to be so to me, and
yes cls_group is quarky in its practise (but thats a separate issue)
and even if it did oops in cls_group - this change above is a memory
leak and needs to be fixed in -stable.

Oopsing in classify is after the fact though. It should not have been
linked to begin with (because wrong config was passed from user space).
As far as cls_group is concerned that is an illegitimate config - thats
why it failed it.

What were you suggesting to change in cls_group to avoid this oops?

Indeed - call it "We add/link unconfigured tp".

I think checking the head (tp->root) for NULL like in cls_fw or
cls_route should work.

I agree.
I think cls_cgroup should check head(tp->root) whether NULL or not
like other classifiers, too.

But I think it's problem adding/linking unconfigured tp, too.

I'm sorry, I don't investigate well, so I don't understand where
unconfigured tp is destroyed, yet.
If you don't mind, could you tell me where it's destoryed?

IMHO that is a workaround for the tp linking bug
[IOW, there is no need to check for tp->root == NULL (in the fast path)
if such an illegal tp was never linked to begin with (on the slow
path)].

So those classifiers you point to need to be fixed afterwards (but 
not -stable material).
My thinking of fixing them to do proper init/get as well later.

Would you agree that it is/was a bandaid?
Or maybe you have some other fear that this may break something else and
prefer the workaround instead?

Sure, after fixing it properly we should get rid of unneeded checks.

If somebody decided to do it this way instead of the "proper" fix then
it looks to me more like a bandaid "by design". And, yes, I have some
fear we could break some strange configs, which could depend on this
wrong but working design.

I think your and my definition of "proper" are at odds here ;->
My logic says there's a causality effect and you always fix the cause
in such a situation. 
Here's the anology of our conversation (some captured above) as i see it
centred around a bug of leaky pipe which just messed up the carpet
overnight in some room:
 
handyman Jamal: fix the pipe so it doesnt leak.
handyman Jarek: put a little bucket below the dripping spot
handyman Jamal: fixing this pipe is cheap - it is on warranty too
handyman Jarek: I fixed two other rooms by putting buckets
handyman Jamal: Proper: fix the pipe - you dont need the buckets forever
handyman Jarek: Proper fix is to put the bucket below any drip

Of course i am exagerating to make a point on our logical approaches:
leaking pipes dont quiet match software bugs i.e.
a dripping pipe will have the short term sense of emergency of needing
buckets but in this case the cost of the damage and time is the same
if you put a bucket or fixed the pipe.

> And, yes, I have some
> fear we could break some strange configs, which could depend on this
> wrong but working design.

To continue our discussion
handyman Jamal: What is your fear about fixing the pipe?
handyman Jarek: Someone may have plants which depend on the drips;
so if you fix it his plants wont get water anymore.

I hope the above doesnt offend you - it is meant in good spirit.

Yes, you're exagerating; my point is:
handyman Jarek: Proper fix is to fix the pipe, but since this hole
is so old and there were other handymans who couldn't miss this let's
do it with caution (2 way).

Yes it oopses in cls_cgroup_classify(). Here is the first report:
http://permalink.gmane.org/gmane.linux.network/128593

We add/link unconfigured tp, but it could be destroyed later, so I
wouldn't call this a memory leak.

Current patch has two places with:

Sorry, but I don't think this change is enough; tc filter replace
with only this (n->nlmsg_type == RTM_NEWTFILTER &&
(n->nlmsg_flags&(NLM_F_CREATE))) can get here with an "old" tp
and will relink it or destroy depending on the ->change() return.

If somebody runs tc add filter with a new priority but existing handle
a newly created (and not linked now) tc would be handled with goto
errout and would leak, I guess.

This would imply the classifier is buggy. I will stare at the different
classifier - and if any exhibits such traits it needs to be fixed

Excellent point - there could be buggy user space apps that will do
that. Minoru change the check to:

+               if (n->nlmsg_type == RTM_NEWTFILTER &&
+                   (n->nlmsg_flags&NLM_F_CREATE &&

I couldnt find any case where this is possible in the current code. If
you have a specific example, we need to fix it.

But then, there could be "tc filter replace" with only this
(n->nlmsg_type == RTM_NEWTFILTER && (n->nlmsg_flags&(NLM_F_CREATE)))
which can't get here with a newly created tp, I guess.

I'm almost sure these commands (right or wrong) can trigger such a leak:

$ sudo tc qdisc add dev lo root handle 1: htb
$ sudo tc filter add dev lo proto ip pref 1 handle 800::1 u32 match u32 0 0 classid 1:1
$ sudo tc filter add dev lo proto ip pref 2 handle 800::1 u32 match u32 0 0 classid 1:1

Right - because in that case tp would already exist and would
be found in the lookup.

You are good - A tip of my hat and a wag of my finger at you;->
Ok, now i looked a lot closer at all 8 classifiers
and u32 is the only one that can fault. It just needs to be fixed.
I will wait until Minoru's patch and then i will submit a fix for it.
Of course the commands from user space are a little rude ;->

But how about that (of course extremely rude) case "tc filter replace"
is run with a new prio?

Jarek, sir, handyman extraordinaire, handsome devil, and lover of
kittens I humbly opine that we need to handle that case. 
How about going back to your original idea of defining tp_created? With
apologies to Minoru (he must be thinking we are lunatics by now), how
does the attached changed patch look to you?

Before you throw another rock, there is another issue which will be
caused by this rude misconfig:
"replace" really means "get rid of the old and add this new one".
But for the last 50 years we do not "get rid of the old". I cant think
of a clean way to do it sans shaving one of the kittens. One simple
thing to do is to printk a warning when detecting this error. I think
one needs to draw a line where bad config affects your life - in this
case i dont think it is worth big changes..

It looks good to me, because it's simple and really understandable.
I think below issue should separate from above patch, because it's
easy to come to understand a patch.

How about that?
If it's ok, I'll test it tomorrow.

Actually, I'd insist with the old rock and handling that other rude
u32 case, at least until it's fixed in place. So I attach my version
of your patch (additionally I removed a pair of braces because of
checkpatch warning).

Alas, I still think we don't need to change so much in -stable to
fix the cls_cgroup oops, so I attach a patch which I think is
enough for -stable and probably -net too. It could be "reverted"
in -net-next just after applying cls_api patch. Of course, treat
it only as my humble proposal, and feel free to recommend to David
your version, no problem (really).

Sure, it doesnt complicate anything - Minoru, this is the version to go
for.

My view is the same - that the second patch doesnt fix the root
cause; and it is not that complicated to fix the root cause. So I humbly
disagree with you.

The issue is that a classifer (cls_group in this example) is being
misconfigured. It rejects the config - but the tp has already been
added. 
It then tries to use the tp in the fast and fails. 

If you look as closely as you did with the patch i posted, youd find
ways to construct similar hostile misconfigs for other classifiers.
You just need to create the scenario where the attributes will fail to
validate. 

I actually suspect the most common scenario for such a failure is not
that head is null (I doubt in Minoru case that allocation will fail);
rather it is some reference to head->something.

cheers,
jamal

The patch #2 is obviously worse and fixes less (of course it still
needs testing for Minoru's case), but I'm 100% confident it can't
introduce any regression (neither take 1 nor 2), which is much harder
to say about patch #1, considering various "rude" configs we could
miss (but we could give them some time to show off). But, as I've
written before, I'm really (really) OK with your decision.

Thanks for the courtesy.
I note Dave already swallowed Minoru's patch; so lets move from there.
Yes, there's a possibility of a regression - I (and so are you) are only
recently evolved humans; we are not perfect... yet ;->
So i would agree with Minoru testing your patch as plan B in case the
applied one starts causing trouble.
BTW, ok - here's a quick untested, uncompiled fix to the u32 classifier
to fix the first rock (which you already worked around in your changes
to the included patch). No rush to submit for now..

On the second rock you threw so violently, after some reflection, I
think it is ok to send a replace twice with different priorities.
The second one will be added and the old not deleted, but if the user
has chosen the correct priority, then things will work out just fine.
And if they want they have to explicitly delete the one they dont want.
It is also not illegal to do a "replace" for installing instead of
"add".

So the only other things left to do from this exercise are (no rush in
any of them):
a) remove all "buckets" from underneath other classifiers
b) get consistency across all classifiers in usage of setup API

If you want to do this - go ahead; else i plan on tackling it probably
when stable 2.6.31 kicks in.

jamal

Thanks for your courtesy as well. Alas, I'm not sure I can fully
understand the current patch. You seem to redefine the ->get() method
usage, so it looks for handle only for configured tp's. It might be
right but I need more time to check this.

I've tested Jarek's patch #1(for cls_api.c).
It works fine to me. Thanks Jarek.

Actually, as far as I can remember, it's your patch with slight
modifications by Jamal and me. So please Minoru, resend this patch
as Jamal previously suggested: with your changelog and Jamal's,
plus maybe mine (if you don't mind) signed-off-by's.

Thanks,

Yes please - even if it is for reasons of givein Jarek some peace of

If something goes seriously wrong with other classifiers because of the
patch, and Jareks patch works, we can back out the current patch and fix
it with that approach.

Hi Minoru,

I hate to do this to you after i made suggestions on how to
make the changes.... (as an adult i hate it when people do it to
me;->)
But sometimes code helps. So what i meant is the attached patch.
I havent even compiled it yet.
If it works, please submit it and add yourself as the author
(and a signed-off from me). Then we can revisit the init()
issue in cls_group..
You should also cc tgraf in your cls_grp config questions.

cheers,
jamal

I investigated this problem, and I found a bug in tc_ctl_tfilter() in net/sched/cls_api.c.

When 'tc filter add' command is executed and proto-tcf does not exist, 
tcf_ctl_tfilter() allocates, initializes and chanins proto-tcf(tp) to
cops->tcf_chain()'s chain before calling tp->ops->change().

If tp->ops->change() returns an error, tcf_ctl_tfilter() returns an error
too, but proto-tcf(tp) is not unchained yet. 

I think tcf_ctl_tfilter() shouldn't chain proto-tcf to the chain before it returns
an error.

Hi Thomas

I have a question about how to use cls_cgroup.

The cause of panic will fix soon. (Now I'll make a patch and will test it.)

I want to know how to use cls_cgroup correctly, so could you tell me how to use it if my operation is wrong. 
Now, I think I might have to specify 'handle' with tc command line, is this true?
But when I specified 'handle', I faced oops. X-P

I investigated this problem, and I found a bug in cls_cgroup_change() in cls_cgroup.c.
cls_cgroup_change() expected tca[TCA_OPTIONS] was set from user space properly,
but tc in iproute2-2.6.29-1 (which I used) didn't set it.

I saw the current source code of tc in git, I found the code for cls_cgroup in iproute2/tc/f_cgroup.c.
It set tca[TCA_OPTIONS].

  git://git.kernel.org/pub/scm/linux/kernel/git/shemminger/iproute2.git

# Unfortunately, current source coude of iproute2 couldn't compile, because it occured compile error. X-P
# But this is another issue.

If we always use a newest iproute2 in git when we use cls_cgroup, we don't face this oops probably.
But I think, kernel shouldn't panic regardless of use program's behaviour.

This patch looks OK to me, but I guess you should add some title (plus
"[PATCH]" in the subject), and a changelog (with lines width <= 80).

Lets just ignore the need for these changes since the patch fixes them
for now. I would still like to make the changes i suggested but later
with more thought put into them.

After the second look I have some questions:
- if it's really aimed to skip checking by ->get() tp's before they're
configured in ->change(), maybe instead of using tp_c to check this it
would be simpler to generally skip calling ->get() for newly created
tp's?

- it seems this method would also need adding a 'handle' lookup to

[BUG] net_cls: Panic occured when net_cls subsystem use

[Minoru Usui]

Hi

Unfortunately this is only panic report.

I used cgroup net_cls subsystem, then kernel panic occured.
I attach panic message and kernel config in this mail's last paragraph.
If my operation is wrong, could you tell me how to use net_cls and
where the documentation is. 

# But I think panic is very bad even if my operation is wrong.

System Environment:
  kernel: 
    * 2.6.29.1 on x86_64
    * 2.6.29.3 on x86_64
    * 2.6.30-rc6 on x86_64 
       (panic occurred same sequence but I couldn't confirm if it was
        same problem. 
        Because crash couldn't analyze kdump of 2.6.30-rc6. 
        This is just the crash utility(analysis tool) problem. X-<) 

  tc: 
    * iproute2-2.6.29-1
      (download from http://devresources.linux-foundation.org/dev/iproute2/download/)

How to reproduce:
  1. mount net_cls subsystem

      # mkdir /cgroup
      # mount -t cgroup -onet_cls none /cgroup

  2. set qdisc, class by tc

     # tc qdisc add dev bond0 root handle 1: htb default 30

     # tc class add dev bond0 parent 1:1 classid 1:10 htb rate 10mbit
     # tc class add dev bond0 parent 1:1 classid 1:20 htb rate 20mbit
     # tc class add dev bond0 parent 1:1 classid 1:30 htb rate 30mbit

  3. set net_cls.classid (classify to classid 1:10)

     # echo 0x1000a > /cgroup/net_cls.classid

  4. set filter in order to use net_cls

     # tc filter add dev bond0 protocol ip parent 1: prio 1 cgroup
       -> panic occured!

Step 3 and 4, I referred to the following mails, because I couldn't find any other useful documentation.
