[PATCH 0/4] tty: Hold write ldisc sem in tty_reopen()

[PATCH 0/4] tty: Hold write ldisc sem in tty_reopen()

[Dmitry Safonov]

Two fixes for potential and real issues.
Looks worth to have in stables as we've hit it on v4.9 stable.
And for linux-next - adding lockdep asserts for line discipline changing
code, verifying that write ldisc sem will be held forthwith.

I couldn't verify that holding write lock fixes the issue as we've hit
it only once and I've failed in reproducing it.
But searching in lkml, Cc'ing here people who probably had the same
crash (and in hope someone of them could give tested-by):

[PATCH 1/4] tty: Drop tty->count on tty_reopen() failure

[Dmitry Safonov]

In case of tty_ldisc_reinit() failure, tty->count should be decremented
back, otherwise we will never release_tty().
Never seen it in the real life, but it seems not really hard to hit.

I did see it. And this fixes it.

I would just do:
  if (!retval)
    tty->count++;
here. Nobody from ldiscs should rely on tty->count.

I thought about that and probably should have described in commit
message why I haven't done that: I prefer to keep it as was as I did Cc
stable tree - to keep the chance of regression to minimum.

I agree that your way is cleaner, but probably it may be done as
cleanup on top for linux-next..

[PATCH 2/4] tty: Hold tty_ldisc_lock() during tty_reopen()

[Dmitry Safonov]

tty_ldisc_reinit() doesn't race with neither tty_ldisc_hangup()
nor set_ldisc() nor tty_ldisc_release() as they use tty lock.
But it races with anyone who expects line discipline to be the same
after hoding read semaphore in tty_ldisc_ref().

We've seen the following crash on v4.9.108 stable:

BUG: unable to handle kernel paging request at 0000000000002260
IP: [..] n_tty_receive_buf_common+0x5f/0x86d
Workqueue: events_unbound flush_to_ldisc
Call Trace:
 [..] n_tty_receive_buf2
 [..] tty_ldisc_receive_buf
 [..] flush_to_ldisc
 [..] process_one_work
 [..] worker_thread
 [..] kthread
 [..] ret_from_fork

I think, tty_ldisc_reinit() should be called with ldisc_sem hold for
writing, which will protect any reader against line discipline changes.

Note: I failed to reproduce the described crash, so obiviously can't
guarantee that this is the place where line discipline was switched.

Seems that you are not the first one to hit this NULL deref.

Per https://lore.kernel.org/patchwork/patch/777220/

: Note that we noticed one path that called reinit without the ldisc lock
: held for writing, we added that, but it didn't fix the problem.

And I guess that Ben meant the same reinit path which you patched:

Probably, it's worth to know what exactly has he tried and what was the
backtrace he got in the result..
Hopefully, we'll hear more.

It might be also worth to review tty_ldisc_deinit(), I thought it's
safe to destroy ldisc there under tty lock during tty release, but may
be that is another non-safe place.

Why 5 secs? This would cause random errors on machines under heavy load.

So what about:
        tty_ldisc_lock(tty, MAX_SCHEDULE_TIMEOUT);
        if (!tty->ldisc)
                ret = tty_ldisc_reinit(tty, tty->termios.c_line);
        tty_ldisc_unlock(tty);

        if (!ret)
                tty->count++;

        return ret;

I forgot to add that I debugged a different NULL ptr deref to this very
same root cause today (set_termios called with NULL tty->disc_data). So
really, tty_reinit's ldisc change must be protected by the ldisc_sem,
otherwise other threads will see tty->ldisc, but not tty->disc_data.

Yeah, I think MAX_SCHEDULE_TIMEOUT will make more sense here..
Not sure, why I decided to go with 5*HZ instead.
Will resend with new timeout, if everything else looks good to you.
(having in mind my argument for count++ in 1/4)

This will be same with a report at
https://syzkaller.appspot.com/bug?id=f08670354701fa64cc0dd3c0128a491bdb16adcc .

syzbot is now testing a patch from Jiri Slaby.

Yes, my patch passed, so could you add:
Reported-by: syzbot+3aa9784721dfb90e984d@syzkaller.appspotmail.com

(not adding tested-by as this particular patch was not tested, but
shoiuld work the same way.)

Tested with all 4 patches applied using syzbot-provided reproducer and
my simplified reproducer. No crashes and no lockdep warnings.
Also, noisy messages like

  pts pts4033: tty_release: tty->count(10529) != (#fd's(7) + #kopen's(0))

are gone. Very nice. Thank you.

fwiw, thanks to 1/4…

Dmitry, could you note the message above to the commit log of 1/4, so
that we know the patch fixed that and downstream can pick it up...

Here, it just seems to wait for input from the user.

Hmm, I assume there is another task waiting for write_ldsem and that one
prevents these readers to proceed. Unfortunately, due to the defunct
__ptrval__ pointer hashing crap, we do not see who is waiting for what.
But I am guessing all are the same locks.

So I think, we are forced to limit the waiting to 5 seconds in reopen in
the end too (the same as we do for new open in tty_init_dev).

Dmitry, could you add the limit and handle the return value of
tty_ldisc_lock now?

thanks,

Hmm, and the writer is not able to grab it because there is already
reader who uses console, I suppose.
I wonder if we can add re-acquiring for the reader side..
That will make write acquire less likely to fail under the load.
I'll try to reproduce it.

Hmm, interesting. Am I getting it right that the test did pass before.
And now we see that sort of/smells like live-lock right after the
introduction of tty_ldisc_lock() to tty_reopen().

If I got it right, LKP did test the 5*HZ patch

	retval = tty_ldisc_lock(tty, 5 * HZ);

At least it's
 In-Reply-To: <20180829022353.23568-3-dima@arista.com>

and
 Message-Id: <20180829022353.23568-3-dima@arista.com>

is the patch which does the 5*HZ lock timeout thing.

Yeah, I also noticed on the weekend that the commit in the mentioned
branch is from v1..

Currently, I tried to reproduce it like ~15-20 times, but unlucky :(

It looks like, the lockup wasn't introduced by this commit, but
unfortunately the commit made it more likely. At least, that's what I
suppose after I've found this report:
https://lkml.org/lkml/2017/11/21/216

It seems to me that the lockup is triggered by:
[  244.948503] 2 locks held by askfirst/235:
[  244.949439]  #0: (____ptrval____) (&tty->ldisc_sem){++++}, at:
tty_ldisc_ref_wait+0x25/0x50
[  244.951762]  #1: (____ptrval____) (&ldata->atomic_read_lock){+.+.},
at: n_tty_read+0x13d/0xa00

Looking into this..

[PATCH 3/4] tty: Lock tty pair in tty_init_dev()

[Dmitry Safonov]

It's safe to not lock both here - done to silence attempt lockdep assert in
tty_ldisc_open(), which will be added with following patch.

Sure, 4/4 patch adds lockdep_assert_held() into tty_ldisc_open().
Currently ldisc in tty->link isn't locked, which according to code
shouldn't be an issue, as far as I can see.

So, this patch silences lockdep warining by holding the semaphore,
which is slowpath anyway and doesn't case any new contention.

(actually, not holding the semaphore for slave might be an issue if one
opens slave before it's fully initialized, but I'm not sure if it's
possible).

Eh, no... Adding a lock just to make lockdep happy is a no-go. The
locking in tty is already complex enough.

If that turns out to be a problem, we can apply the patch. BUt unless it
is proven to be so (be it code review or a reproducer), let's leave the
locking as it is.

Ok, than for v2 I'll just remove lockdep_assert() from
tty_ldisc_open().

And thanks a lot for your work on fixing these issues!

I've added Nathan (and centos-virt) to CC, because earlier Nathan was able to reliably trigger ldisc related kernel crash in Xen dom0 when running Linux 4.9 kernel, which seems similar to what your patch 2/4 is trying to fix.

Nathan's kernel crash report: https://lists.centos.org/pipermail/centos-virt/2017-August/005610.html
Example ldisc kernel crash BUG in "n_tty_receive_buf_common": https://lists.centos.org/pipermail/centos-virt/attachments/20170823/45493276/attachment.txt
