Seems odd to me, but I'm seeing:

ummunotify.c:(.text+0x8f217): undefined reference to `__get_user_X'

when building for i386.

The get_user() and put_user() in ummunotify_exchange_features()
are correctly converted to __get_user_4() and __put_user_4(),
but the get_user() in ummunotify_unregister_region() becomes
__get_user_X()  [as seen in objdump output].

toolchain issue or something else??

yes, strange.

.config please?

Try `make drivers/char/ummunotify.i' then have a poke around in ummunotify.i?

Is 64-bit get_user() supposed to work portably?  Because it seems that
arch/x86/include/asm/uaccess.h intentionally makes get_user((__u64))
expand to __get_user_X() and then never defines __get_user_X().  And
arm, say, expands it to __get_user_bad().  But on the other hand,
powerpc and sparc seem to go to the trouble of defining a 64-bit
get_user() for 32-bit builds...

My fault for insufficient 32-bit compile testing.  Andrew, I'll send a
patch to change to copy_from_user() instead.

 - R.

Re: mmotm 2009-08-04-14-22 uploaded (ummunotify)

[Roland Dreier]

Andrew, can you add this into the ummunotify patch, or add it on top or whatever?

Fix

    ummunotify.c:(.text+0x8f217): undefined reference to `__get_user_X'

when building for i386 -- get_user() can't handle u64 on all
architectures, so just use copy_from_user().

Applied, thanks Randy.

The ipv6 side has the same issue, I'll fix that part up myself.

At a guess I'd say that alloc_netdev_mq()->dev_unicast_init() is doing
netif_addr_lock_bh()->spin_lock_bh(&dev->addr_list_lock) prior to
initialising add_list_lock.

Something like this might shut it up:

 	dev_net_set(dev, &init_net);
 

but it'd be better to intialise this thing earlier like:

_

but that might break register_netdevice() for netdevs which were
allocated via other means, dunno.

I would be pointing fingers at

Hmm, it seems addr_list_lock is not initialized at the right place...

commit a6ac65db addded a netif_addr_lock_bh() in dev_unicast_init()

We initialize dev->addr_list_lock in register_netdevice(), we should
init it earlier, right after allocation and before dev_unicast_init()

But dev->type being 0, we probably cannot call netdev_set_addr_lockdep_class()
at this point...

David, what do you think ? Is it safe to call netdev_set_addr_lockdep_class()
in register_netdevice(), after lock being used one time in dev_unicast_init() ?

Thank you

[PATCH] net: Init dev->addr_list_lock in alloc_netdev_mq()
