The goal is to stop setting and using tty->driver_data in devpts code.
It should be used solely by the driver's code, pty in this case.
First, here we remove TTY from devpts_get_tty and rename it to
devpts_get_priv. Note we do not remove type safety, we just shift the
[implicit] (void *) cast one layer up.
index was unused in devpts_get_tty, so remove that from the prototype
too.

The goal is to stop setting and using tty->driver_data in devpts code.
It should be used solely by the driver's code, pty in this case.
For the cleanup of layering, we will need the inode created in
devpts_pty_new to be stored into slave's driver_data. So we convert
devpts_pty_new to return the inode or an ERR_PTR-encoded error in case
of failure.
The move of 'inode = new_inode(sb);' from declarators to the code is
only cosmetical, but it makes the code easier to read.

The goal is to stop setting and using tty->driver_data in devpts code.
It should be used solely by the driver's code, pty in this case.
Now driver_data are managed only in the pty driver. devpts_pty_new is
switched to accept what we used to dig out of tty_struct, i.e. device
node number and index.
This also removes a note about driver_data being set outside of the
driver.

Now that we have control over tty->driver_data in pty, we can just
kill the /dev/pts/ in pty code too. Namely, in ->shutdown hook of
tty. For pty, this is called only once, for whichever end is closed
last. But we don't care, both driver_data are the inode as it used to
be till now.

There used to be a single tty_ldisc_ref_wait. But then, when a
big-tty-mutex (BTM) was introduced, it has to be tty_ldisc_ref +
tty_unlock + tty_ldisc_ref_wait + tty_lock. Later, BTM was removed
from that path and tty_ldisc_ref + tty_ldisc_ref_wait remained there.
But it makes no sense now. So leave there only tty_ldisc_ref_wait.
And when we have a reference to an ldisc, actually use it in the loop.
Otherwise it may be racy.

We reintroduced tty_ldisc_wait_idle in 100eeae2c5c (TTY: restore
tty_ldisc_wait_idle) and used in set_ldisc. Then we added it also to
the hangup path in 92f6fa09bd453 (TTY: ldisc, do not close until there
are readers). And we noted that there is one more path:
~ Before 65b770468e98 tty_ldisc_wait_idle was called also from
~ tty_ldisc_release. It is called from tty_release, so I don't think
~ we need to restore that one.
Well, I was wrong. There might still be holders of an ldisc
reference. Not from userspace, but drivers. If they take a reference
and a user closes the device immediately after that, we have a
problem. ldisc is halted and closed by TTY, but the driver still may
call some ldisc's operation and cause a crash.
So restore the tty_ldisc_wait_idle call also to the third location
where it was before 65b770468e98 (tty-ldisc: turn ldisc user count
into a proper refcount). Now we should be safe with respect to the
ldisc reference counting as all* tty_ldisc_close paths are safely
called with reference count of one.
* Not the one in tty_ldisc_setup's fail path. But that is called
before the first open finishes. So userspace does not see it yet.
Even thought the driver is given the TTY already via ->install, it
should not take a reference to the ldisc yet. If some driver is to
do this, we should put one tty_ldisc_wait_idle also in the setup.

hci_ldisc's open checks if tty_struct->disc_data is set. And if so it
returns with an error. But nothing ensures disc_data to be NULL. And
since ld->ops->open shall be called only once, we do not need the
check at all. So remove it.
Note that this is not an issue now, but n_tty will start using the
disc_data pointer and this invalid 'if' would trigger then rendering
TTYs over BT unusable.

ldisc->open and close are called only once and cannot cross. So the
tests in open and close are superfluous. Remove them. (But leave sets
to NULL to ensure there is not a bug somewhere.)
And when the tests are gone, handle properly failures in open. We
leaked read_buf if allocation of echo_buf failed before. Now this is
not the case anymore.

* BUG_ON(!tty) in n_tty_set_termios -- it cannot be called with tty ==
NULL. It is called from two call sites. First, from n_tty_open where
we have a valid tty. Second, as ld->ops->set_termios from
tty_set_termios. But there we have a valid tty too.
* if (!tty) in n_tty_open -- why would the TTY layer call ldisc's
open with an invalid TTY? No it indeed does not. All call sites have
a tty and dereference that.
* BUG_ON(!tty->read_buf) in n_tty_read -- this used to be a valid
check. The ldisc handling was broken some time ago when I added the
check to ensure everything is OK. It still can catch the case, but
no later than we move the buffer to ldisc data. Then there will be
no read_buf in tty_struct, i.e. nothing to check for.
* if (!tty->read_buf) in n_tty_receive_buf -- this should never
happen. All callers of ldisc->ops->receive_ops should hold a
reference to an ldisc and close (which frees read_buf) cannot be
called until the reference is dropped.
* if (WARN_ON(!tty->read_buf)) in n_tty_read -- the same as in the
previous case.

This is a private member of n_tty. Stop accessing it. Instead, take is
as an argument.
This is needed to allow clean switch of the private members to a
separate private structure of n_tty.

From: Jiri Slaby @ 2012-10-18 20:26 UTC (permalink / raw)
To: gregkh; +Cc: alan, linux-kernel, jirislaby
Here we start moving all the n_tty related bits from tty_struct to
the newly defined n_tty_data struct in n_tty proper.
In this patch primitive members and bits are moved. The rest will be
done per-partes in the next patches.

To: gregkh; +Cc: alan, linux-kernel, jirislaby
atomic_write_lock is not n_tty specific, so move it up in the
tty_struct.
And since these are the last ones to move, remove also the comment
saying there are some ldisc' members. There are none now.

They are only TTY buffers specific. And the buffers will go to
tty_port in the next patches. So to remove the need to have both
tty_port and tty_struct at some places, let us move the flags to
tty_port.

During the move of tty buffers from tty_struct to tty_port, we will
need to switch all users of buf to tty->port->buf. There are many
functions where this is accessed directly in their code many times.
Cache the tty->buf pointer in such functions now and change only
single lines in each function in the next patch.
Not that it is convenient for the next patch, but the code is now also
more readable.

For that purpose we have to temporarily introduce a second tty back
pointer into tty_port. It is because serial layer, and maybe others,
still do not use tty_port_tty_set/get. So that we cannot set the
tty_port->tty to NULL at will now.
Yes, the fix would be to convert whole serial layer and all its users
to tty_port_tty_set/get. However we are in the process of removing the
need of tty in most of the call sites, so this would lead to a
duplicated work.
Instead we have now tty_port->itty (internal tty) which will be used
only in flush_to_ldisc. For that one it is ensured that itty is valid
wherever the work is run. IOW, the work is synchronously cancelled
before we set itty to NULL and also before hangup is processed.
After we need only tty_port and not tty_struct in most code, this
shall be changed to tty_port_tty_set/get and itty removed completely.

To: gregkh; +Cc: alan, linux-kernel, jirislaby
So this is it. The big step why we did all the work over the past
kernel releases. Now everything is prepared, so nothing protects us
from doing that big step.

~~~ ~~ `` ~~~ ~~
The buffers are now in the tty_port structure and we can start
teaching the buffer helpers (insert char/string, flip etc.) to use
tty_port instead of tty_struct all around.

I'm guessing it happens because we never cancel the scheduled work when we
free the buffer, so the scheduled work may run even after we freed the buffer.
Besides the warning itself, I think that 'tty is NULL' would need a newline
after it. Greg, should I send a patch for that?
Thanks,
Sasha

Yes, it reproduces pretty easily while fuzzing.

What is your exact setup? I tried trinity with 100 000 syscalls inside
KVM with an LDEP-enabled kernel. How many serial ports do you have in
the guest? Any USB serials in there?

So you probably want a lot more than 100k syscalls, why limit it at
all actually?
lkvm is emulating 4 serial ports, no USB ports.
I've attached my .config for the guest kernel as reference.
Thanks,
Sasha

Not really:
./trinity -m --quiet --dangerous -l off
Can I add something to my kernel to provide more info when it happens?

Nope, I see the warnings mentioned before, without the new 'HUH' warnings.

Actually it does. It is exactly as you wrote some time earlier. The work
is scheduled after is was cancelled and should not trigger anymore. Or,
it is scheduled before it is supposed to do. Could you try the attached
patch and report what happens with that patch?
PS I can't reproduce by whatever I tried.

Hi Sasha,
Assuming this access-after-free is still reproducible for you, would you
be willing to try the patch below? I tried to reproduce this and
couldn't (with multiple cores and with just single core).
It would distinguish between case A (that the buf work is not being
cancelled) and case B (that the buf work is being scheduled after the
port has already been freed). It should BUG in case B, which would also
expose the call chain. It won't help at all in case A though :\
Regards,
Peter Hurley

I figured out how to make this reproduce easily. The test jig at the end
of this email will generate this multiple times a second.
The test creates a pty pair and spawns a child which writes to the slave
pts, while the parent waits for the first write and then abruptly closes
the master ptm and kills the child. (Just in case, I'd only run the jig
in a disposable vm. Obviously, the vm needs multiple cores and extra pty
serial devices ;)
>From instrumenting the tty_release() path, it's clear that tty_buffer
work is still scheduled even after tty_release_ldisc() has run. For
example, with this patch I get the warning below it.

[ Please note: this analysis only refers to the pty driver. The
situation with hardware drivers has further complications.]
Firstly, this problem predates Jiri's changes; only because he was
cautious by checking the lifetime of the itty in flush_to_ldisc(), did
he uncover this existing problem.
One example of how it is possible for buffer work to be scheduled even
after tty_release_ldisc() stems from how tty_ldisc_halt() works (or
rather doesn't). (I've snipped out the relevant code from tty_ldisc.c
for annotation below.)
tty_ldisc_halt() has only 2 callers; tty_release_ldisc() and
tty_set_ldisc(). A 3rd code site -- tty_ldisc_hangup() -- has similar
logic.
The idea behind tty_ldisc_halt() is to prevent __future__ use of this
ldisc (since users are required to acquire an ldisc reference via
tty_ldisc_try() -- also below). Annotations are mine.
----------------------------------
static struct tty_ldisc *tty_ldisc_try(struct tty_struct *tty)
{
unsigned long flags;
struct tty_ldisc *ld;
/* this spin_lock is irrelevant to this discussion */
spin_lock_irqsave(&tty_ldisc_lock, flags);
ld = NULL;
/*
* Atomically test if __new__ ldisc references are
* allowed. Please note, there can be any number of
* existing users (ie., outstanding references).
*/
if (test_bit(TTY_LDISC, &tty->flags))
ld = get_ldisc(tty->ldisc);
spin_unlock_irqrestore(&tty_ldisc_lock, flags);
return ld;
}
static int tty_ldisc_halt(struct tty_struct *tty)
{
/* Prevent any __new__ ldisc references from being acquired. */
clear_bit(TTY_LDISC, &tty->flags);
/* Since __existing__ ldisc references can still schedule new
* buffer work (via tty_flip_buffer_push()), the cancellation
* below is pointless. The instant that cancellation completes
* an existing ldisc user can schedule new work.
*
* At a minimum, we must wait for all ldisc references **here**
* rather than **after** cancelling the work.
*/
return cancel_work_sync(&tty->buf.work);
}
**** A special note about locking *****
Locking around tty_ldisc_halt() ...
- does not prevent existing ldisc users from continuing to use the ldisc
- is unnecessary for the 3 'callers' because all 3 are trying to
accomplish the same goal by the same means
- can deadlock. Reference: https://lkml.org/lkml/2012/11/21/267

Naturally, I found the least obvious problem first.
The more obvious problem is that the pty driver doesn't have an ldisc
reference to the 'other' tty when pty_write() is called. So doing the
tty_flip_buffer_push() has scheduled buffer work for a potentially
halted ldisc.
static int pty_write(struct tty_struct *tty, const unsigned char *buf, int c)
{
struct tty_struct *to = tty->link; <==== this is the 'other' tty
if (tty->stopped)
return 0;
if (c > 0) {
/* Stuff the data into the input queue of the other end */
c = tty_insert_flip_string(to, buf, c);
/* And shovel */
if (c) {
tty_flip_buffer_push(to);
tty_wakeup(tty);
}
}
return c;
}
There are several possible ways to fix this:
1. Halt both ldiscs and ensure that both ldiscs have no outstanding
references before cancelling their work.
2. Claim an ldisc reference for the 'other' ldisc in things like
tty_write().
3. I'm sure there's other ways....

Peter Hurley
