Hi Linus,
On top of the for-3.5/core pull request, here are the driver related
changes for 3.5. It contains:
- The floppy changes from Jiri. Jiri is now also marked as the
maintainer of floppy.c, I shall be publically branding his forehead
with red hot iron at the next opportune moment.
- A batch of drbd updates and fixes from the linbit crew, as well as
fixes from others.
- Two small fixes for xen-blkfront courtesy of Jan.
Please pull.

pty: Fix lock inversion
The ptmx_open path takes the tty and devpts locks in the wrong order
because tty_init_dev locks and returns a locked tty. As far as I can
tell this is actually safe anyway because the tty being returned is new
so nobody can get a reference to lock it at this point.
However we don't even need the devpts lock at this point, it's only held
as a byproduct of the way the locks were pushe down.

Eric, can you verify that reverting that one commit on top of current
-git fixes things for you?
I'm a bit surprised that it would be that simple commit that actually
just *removes* a mutex use that causes it, so the bisect result looks
a bit fishy. Maybe it's a race that doesn't always cause the lockup at
boot, in which case it might have bisected to the wrong thing..
But if reverting that commit from top-of-tree fixes it, that's pretty
unambiguous.

tty_lock_pair() do the right thing to avoid deadlocks, but should
instruct LOCKDEP of this to avoid a splat.

Latest Linus tree still hang on my machine, at least this patch removes
the lockdep problem...

Bisection gave nothing, because its an old bug ?
Following patch cures it.
[PATCH] block: avoid infinite loop in get_task_io_context()
Calling get_task_io_context() on a exiting task which isn't %current can
loop forever. This triggers at boot time on my dev machine.
BUG: soft lockup - CPU#3 stuck for 22s ! [mountall.1603]
Fix this by making create_task_io_context() returns -EBUSY in this case
to break the loop.

Eric, do you have a task trace to go with this lockup, where task !=
current?
In any case, it is a legit bug fix. I have applied it.

That's good enough, then it all makes sense. I guess we could be
checking PF_EXITING earlier, but I think the patch is fine as-is.

I have submitted very similar patch to Greg/Alan already 3 days ago[1],
but have been told that this is already fixed. Apparently it wasn't?

I saw that right now.
Not sure your patch is the right fix with hard coded 1 and 2 values ?
0 and 1 should be enough.

Ok, DEBUG_PAGEALLOC and with that offset fairly early in tty_shutdown,
it's almost certainly one of the accesses in the
tty->driver->ops->remove
chain when it does the (inlined)
tty_driver_remove_tty(tty->driver, tty);
you could check which one it is at that offset 0x15, but I think both
the ops and the driver structures should be statically allocated, so I
suspect it's the "tty" itself that is already freed.
Odd. But yes, smells very much like a refcount issue, probably due to
broken locking. Does the problem go away if you revert commits
d29f3ef39be4 ("tty_lock: Localise the lock") and 3af502b96649
("tty_lock: undo the old tty_lock use on the ctty")?

Might be worth checking tty->magic in queue_release_one_tty and the
entry to release_one_tty
You can also turn on TTY_PARANOIA_CHECK defines which may show more but
can also be mistriggered in a few cases.
What distro setup is this and is it booting to run level 3 or 5. I'm
just wondering which paths you hit. Some of the distros do weird stuff
(notably Fedora is totally broken on the console management) and that
might be hiding a race or two in saner cases where you get more console
hangups.

Tried this but seems not straightforward, and its pretty late here in
France, week end starting ;)
By the way, release_one_tty() uses the following racy code :
tty_driver_kref_put(driver);
module_put(driver->owner);
I would use following patch to make sure bad things cant happen...

driver and driver->ops is basically const and it's not what you'd expect
from a tty refcount bug. The driver side puts shouldn't have changed but
I'll take a look over that patch and the error paths closely again just
in case.
It could be that tty->driver is pointing at a valid but bogus location
but again its not something I'd expect.

Agreed. Although we wouldn't be unloading console or pty so it's alas not
the real cause.

right
The code looks like :
...
call mcount
mov %rdi,%rbx
mov 0x10(%rdi),%rdi tty->driver

So tty was freed an tty->driver contains 6b6b6b6b6b6b6b6b

Seems good, but am still doing reboots to make sure.
We should add a debugging code to kref to catch poisoned refcounts...
Something like :
[PATCH] kref: detects poisoned refcounts
Catch kref_get() done on freed memory, if slub/slab are poisoning the
freed area.

I'll have a look at this ASAP - I think the driver ref counting side is a
red herring but I'll build an Ubuntu 12 setup and try and replicate the
crash once I'm back at work (its a national holiday here Sat-Tue for the
English queens jubilee)

I'm seeing *something* odd.
We call tty_shutdown() without holding the tty_mutex as far as I can
tell. Which means that we remove the tty from the tty lists with *no*
serialization with looking them up.
The fact that we lock the tty *after* we have found it is kind of
irrelevant. By then it's too late.
And I think this is the fundamental bug that was introduced in commit
d29f3ef39be4 ("tty_lock: Localise the lock"). We *used* to do
tty_lock() before the lookup - early in tty_open(). And we held it
until the very end of tty_release(), so the tty lock actually
protected the lookup of the tty.
That's simply not true any more. The comments for
tty_driver_remove_tty() say "Locking: tty_mutex for now", but that's
just garbage and wishful thinking. The callers don't actually hold
tty_mutex, and never have. Sure, some of them may do so (there's a lot
of potential callers through tty_kref_put()) but most of them
definitely don't. Look at tty_release(), most of the final refcounts
will be dropped after the mutex_unlock(&tty_mutex) afaik.
I'm pretty sure this is the bug. And there's no way we can make
'tty_mutex' protect every tty_kref_put(). So I think we have two
options:
- revert all the tty locking changes
- make a new global lock that protects just driver->ops->lookup(),
driver->ttys[idx], and driver->ops->remove()
Hmm?

I've been working on the latter as a later step already. It triggers a
whole set of other horrible problems about synchronization between
driver->ttys[] and driver->termios.
Can we just punt the tty localisation patches for a release (the last
console one before it is fine).
This isn't urgent stuff, its gradual cleaning the kernel up stuff and if
we keep it in -next for another cycle while fixing up these cases there
will be no hardware not supported, nobody unable to use their system, no
regressions. Better to get it right first because its ugly and
complicated as hell.

Ok, here's the second option. THIS PATCH IS TOTALLY UNTESTED!
Basic concepts:
- the tty driver lookup is protected with "tty_lookup_mutex",
similarly to how the "current task mutex" is protected by the signal
lock.
- At lookup, we now always increment the kref (which in the case of
tty_open_current_tty() means that we do *not* drop the kref), and in
the case of a tty driver lookup, we use "atomic_inc_not_zero()" to
make sure that we get a tty that is not on its way out.
I *think* this makes sense. But it has has had absolutely zero
testing. It compiles in my config, and the locking is at least
sensible and well-localized, but maybe I'm missing something.
Comments?

Yep. Been that way 8)
tty_driver_remove_tty is called from tty_shutdown is called from the
final tty_kref_put can be called from IRQ context.
If you move the tty_driver_remove_tty into the queued part of the code
path then driver->termios[] races appear between the destructor and the
next allocation of the same tty.
Really tty_driver_remove_tty should occur at the end of tty_release, and
tty->termios should simply be a struct ktermios (its a fairly small
structure) and copied back to the drivers array on drivers that need it.
That cleans up pty as well.

Hmm. Ok. Looking at it, the ".shutdown" and ".remove" functions are
all very limited, so I suspect we could just make the rule be that the
install/lookup functions are serialized against each other by the
pty_mutex (true today), and then we just add a small spinlock for the
actual driver array insert/lookup.
So my patch could probably be munged to do something like that.
But since I want to close the merge window and release -rc1 today, it
does feel too late to start mucking with fundamental locking things.
So reverting is likely the right thing to do.
Can somebody double-check the attached revert commit? Did I miss some
commit that depended on the tty locking changes?
Eric, does this make things work for you again? When/if we get the
locking sorted out for the tty install/lookup/remove, we can revert
this revert and do the locking fixes on top of that.
Alan, please double-check my revert. I've done an allmodconfig build
with it, and I've looked at the patch and grepped that I didn't miss
any 'tty_[un]lock()' cases, but that's the limit of my
sanity-checking. I did check that this revert means that the main tty
files are now back in the same exact state they were before that
"tty_lock: Localise the lock" commit. I left the per-ldisc waitqueue
change in there, though, that one seemed independent.

per ldisc waitqueue is indeed independent. The rest I'll try and check
but may be Wednesday for a serious check. You could also I guess narrow
the check by leaving it all passing tty in to the lock function but just
using the global lock. Might keep the noise down for the 3.6 work too.

Not really possible. The bug fundamentally comes from how the per-tty
locking locks too late - after the lookup - rather than before.
And fixing that to lock in the right place is not possible with the
"pass in the tty" model. Because we don't know what the tty will be.

Actually, I think we could probably make it really trivial by forcing
the free'ing of the tty itself to be RCU-delayed.
Then shutdown/remove would remove the entry with no locking
what-so-ever (which is really nice if you're in an interrupt - because
now *other* users don't need to use those annoying irq-safe versions),
and simply just clear the ttys[] array index.
The lookup side would need to just do a RCU read lock, read the
->ttys[index] thing using ACCESS_ONCE, and then just do the
atomic_inc_not_zero() dance I already did to validate that the thing
is still alive.
Voila - very cheap locking, and the part that could possibly happen
from interrupts (shutdown/remove) needs no locking at all.
Making the tty freeing be rcu-delayed sounds pretty dang simple too.
What do you think?
Anyway, I'm closing the merge window now (doing the tagging, booting
and checking that allmodconfig/allyesconfig/allnoconfigs all compile
fine) so it's 3.6 material, but it doesn't sound bad.

It doesn't solve the problem of the synchronization between ->ttys[] and
->termios[]. Thats two objects, and the root of the problem. Given the
size of struct ktermios it appears to be a win anyway to put it in the
tty.
At that point tty_release can do what it should do.

Second complication is some ttys have their own private ->shutdown.
It's possibly a useful optimisation and way of doing it *once* the
termios tidy is done, but I think once that is done then ->shutdown goes
away or becomes an non IRQ path event in tty_release.

I've been gradually putting in places the bits leading up to the tty_lock
fix. I hadn't realised that one needed to be ahead or was exposing the
termios/tty array race.
I'll just go back and put the termios stuff further ahead and get that
chunk right first. After that tty locking, and then we can worry about
the real nasty which is that if we fix the open/close paths for console
devices to be secure Fedora breaks because their userspace appears to be
completely broken in this area.

Linus, I confirm all is good with 3.5-rc1
Thanks
