Sorry, I cant see same messages in your dmesg, no mention of stuck
processes (blocked for more than 120 seconds.)
By the way, please update to latest 3.1.rc10

I actually don't see the rtnl_lock or mutex_lock that was listed in your
original dmesg. There are a lot of warning traces from mac80211.c.
The other interesting thing is the following:

There is another thread title "iwlagn is getting very shaky". It makes
me wonder.
Where did you get your kernel from. From you dmesg I see:
Linux version 3.1.0-rc6-gbee709a (nico@brief)
I tried to locate the SHA1 bee709a but it is not in my repository. I
want to look what the warnings from mac80211 mean.

Triggered it!
And also got the traceback!
Dmesg + log attached, let me know when I can pull the fix from
somewhere.

Yes, I think it resolves any doubt. I will resubmit with this
solution.

The Ethernet MAC driver decides what to do with the original skb. In
the MAC driver, it goes like:
1. skb_tx_timestamp(skb) -> skb_clone_tx_timestamp(skb);
2. give skb to hardware;
3. ...
4. kfree_skb, recycle, etc

Yeah that seems like it works and just drops the timestamp in case we
don't still have a live socket, which is perfectly fine.

Yes, the sock_hold() could be changed by an atomic_inc_not_zero()
What about doing this ?

Fair enough :-)

Ok.
Anyway, I guess you agree that the patches as-is aren't actually the
right solution since we can't sock_hold() a TX skb socket reference?

Serge this approach is wrong.
Because we pass the cred and the pid through the socket socket itself
is just a conduit and should be ignored in this context.
The only interesting test should be are you allowed to impersonate other
users in your current userk namespace.
So it should be possible to simplify the entire patch to just:
static __inline__ int scm_check_creds(struct ucred *creds)
{
const struct cred *cred = current_cred();
+ struct user_namespace *ns = cred->user_ns;
- if ((creds->pid == task_tgid_vnr(current) || capable(CAP_SYS_ADMIN)) &&
- ((creds->uid == cred->uid || creds->uid == cred->euid ||
- creds->uid == cred->suid) || capable(CAP_SETUID)) &&
- ((creds->gid == cred->gid || creds->gid == cred->egid ||
- creds->gid == cred->sgid) || capable(CAP_SETGID))) {
+ if ((creds->pid == task_tgid_vnr(current) || ns_capable(ns, CAP_SYS_ADMIN)) &&

+ creds->gid == cred->sgid) || ns_capable(ns, CAP_SETGID))) {
return 0;
}

Either we can guarantee that, or kernel is a piece of crap, all bets are
off.
Yes, we need to make an audit, since we assumed sock_hold() was the
right thing to do in all contexts.

Where do you see a race? If you do sock_hold() while you have a 'proper
sk_refcnt reference', this does nothing but increase sk_refcnt. If you
do sock_hold() while you have an 'sk_wmem_alloc reference', this will
actually increase sk_wmem_alloc by 1; then when the original
'sk_wmem_alloc reference' you had when calling sock_hold() is released,
sk_wmem_alloc will still have 1 matching a non-zero sk_refcnt.

Even with that fixed I'm not really convinced of it all -- need to
really really really make sure that no skb->sk that was owned by a TX
skb is ever passed to sock_hold(). Can we really guarantee that?

I think I misremember -- I was suggesting to set skb2->truesize to 1 and
then charge it so it's not double-charged.
OTOH, could skb_clone_tx_timestamp() orphan the original skb after
adding the skb2?

Hmm, it will be difficult to handle two atomics without adding races,
and add quite expensive atomic_inc_return() on some arches.
I would just change the skb tx cloning to take a normal reference on
sk_wmem_alloc
atomic_add(skb->truesize, &sk->sk_wmem_alloc);
instead of
sock_hold(sk);

Well, yeah, ok, but Richard's patches do modify sk_refcnt, and can't
modify sk_wmem_alloc as discussed upthread.
I'll admit that I don't really trust the whole thing anyway -- it seems
rather error prone to forbid you from doing sock_hold() on a socket you
obtained from a TX packet.

Right, make all told me to setup CONFIG_LOCKDEP_SUPPORT=y, but I've
setup CONFIG_LOCKDEP=y manually in .config as I haven't found the entry
in menuconfig.
It seems that this option was removed from .config in the build process,
though.
Should I set it up via

?

config LOCKDEP
bool
depends on DEBUG_KERNEL && TRACE_IRQFLAGS_SUPPORT && STACKTRACE_SUPPORT && LOCKDEP_SUPPORT
select STACKTRACE
select FRAME_POINTER if !MIPS && !PPC && !ARM_UNWIND && !S390 && !MICROBLAZE
select KALLSYMS
select KALLSYMS_ALL

Why can't sk_free() have been called? I'm not thinking of sock_wfree()
which can't have been called -- so the socket surely still exists
because skb->truesize is still accounted to it -- but what says
sk_refcnt hasn't reached 0 yet?

Right.

Right.

This is undoubtedly true, I'm not disputing this.

Not disputing this either. But you said sk_refcnt can be 0, so why can't
the following happen:
/* skb; skb->sk = sk; skb->destructor = sock_wfree; */
/* skb is on qdisc, some time passes */
sk_free(sk); /* user closed socket,
sk->sk_refcnt reaches 0,
sk->sk_wmem_alloc == skb->truesize,
__sk_free not called, socket still lives,
but no more +1 in sk_wmem_alloc */
/* some more time passes */
/* ethernet hard_start_xmit calls skb_clone_tx_timestamp() */
skb2 = skb_clone(skb);
skb2->sk = skb->sk;
sock_hold(skb->sk);
/* ethernet TX completion calls skb_free(skb) */
skb_free(skb):
sock_wfree(skb); /* sk_wmem_alloc reaches 0,
__sk_free called DESPITE sk_refcnt > 0 */
/* later, in skb_complete_tx_timestamp() */
sock_put(sk); /* KABOOM */
I just want to understand why this can't happen :-)
