[PATCH] rbtree: fix the red root

[PATCH] rbtree: fix the red root

[Qian Cai]

A GFP was reported,

kasan: CONFIG_KASAN_INLINE enabled
kasan: GPF could be caused by NULL-ptr deref or user memory access
general protection fault: 0000 [#1] SMP KASAN

        do_syscall_64+0x1b3/0x820
        entry_SYSCALL_64_after_hwframe+0x49/0xbe

It turned out,

gparent = rb_red_parent(parent);
tmp = gparent->rb_right; <-- GFP triggered here.

Apparently, "gparent" is NULL which indicates "parent" is rbtree's root
which is red. Otherwise, it will be treated properly a few lines above.

/*
 * If there is a black parent, we are done.
 * Otherwise, take some corrective action as,
 * per 4), we don't want a red root or two
 * consecutive red nodes.
 */
if(rb_is_black(parent))
	break;

Hence, it violates the rule #1 and need a fix up.

Good catch, acked. After thinking through the logic a bit your solution
seems like the simplest fix.

Now, I didn't do _extensive_ testing but a quick compile and bootup of
the patch with CONFIG_KASAN_INLINE enabled has yet to throw any GFPs,
so take that as you will.

What change introduced this bug?  We need a Fixes: line so the stable
people know how far to backport this fix.

Breaking commit _might_ be 5bc9188aa207dafd47 (rbtree: low level optimizations in rb_insert_color())

I'm thinking that the when `parent = rb_parent(node);` was
moved from the beginning of the loop to the function initialization
only, somehow parent not being reassigned every loop resulted in
the red root node case.

I'm sort of just guessing here admittedly and I'll do some testing after
breakfast, but nothing else in the `git log` or `git blame` changes really
jumps out at me apart from this one commit.

 void rb_insert_color(struct rb_node *node, struct rb_root *root)
 {
-       struct rb_node *parent, *gparent;
+       struct rb_node *parent = rb_red_parent(node), *gparent, *tmp;

        while (true) {
                /*
                 * Loop invariant: node is red
                 *
                 * If there is a black parent, we are done.
                 * Otherwise, take some corrective action as we don't
                 * want a red root or two consecutive red nodes.
                 */
-               parent = rb_parent(node);
                if (!parent) {
-                       rb_set_black(node);
+                       rb_set_parent_color(node, NULL, RB_BLACK);
                        break;
                } else if (rb_is_black(parent))
                        break;

-               gparent = rb_parent(parent);
+               gparent = rb_red_parent(parent);

It looks like,

Fixes: 6d58452dc06 (rbtree: adjust root color in rb_insert_color() only when
necessary)

where it no longer always paint the root as black.

Also, copying this fix for the original author and reviewer.

Great, thanks!  We have a test-suite (lib/rbtree_test.c); could you add
a test to it that will reproduce this bug without your patch applied?

[PATCH v2] rbtree: fix the red root

[Qian Cai]

A GPF was reported,

kasan: CONFIG_KASAN_INLINE enabled
kasan: GPF could be caused by NULL-ptr deref or user memory access

        do_syscall_64+0x1b3/0x820
        entry_SYSCALL_64_after_hwframe+0x49/0xbe

It turned out,

gparent = rb_red_parent(parent);
tmp = gparent->rb_right; <-- GPF was triggered here.

Apparently, "gparent" is NULL which indicates "parent" is rbtree's root
which is red. Otherwise, it will be treated properly a few lines above.

/*
 * If there is a black parent, we are done.
 * Otherwise, take some corrective action as,
 * per 4), we don't want a red root or two
 * consecutive red nodes.
 */
if(rb_is_black(parent))
	break;

Hence, it violates the rule #1 (the root can't be red) and need a fix
up, and also add a regression test for it. This looks like was
introduced by 6d58452dc06 where it no longer always paint the root as
black.

That's not a fair test!  You're poking around in the data structure to
create the situation.  This test would have failed before 6d58452dc06 too.
How do we create a tree that has a red parent at root, only using insert()
and erase()?

If only I knew how to reproduce this myself, I might be able to figure out how
it ends up with the red root in the first place.

I've been out today but return home tomorrow and can test any suggested fixes, or with different kernel settings.  Just let me know.

Just to clarify, do you have a way to reproduce this crash without the fix ?

I don't think the fix is correct, because it just silently ignores a
corrupted rbtree (red root node). But the code that creates this
situation certainly needs to be fixed - having a reproduceable test
case would certainly help here.

Regarding 6d58452dc06, the reasoning was that this code expects to be
called after inserting a new (red) leaf into an rbtree that had all of
its data structure invariants satisfied. So in this context, it should
not be necessary to always reset the root to black, as this should
already be the case...

I am starting to suspect that my crash was caused by some new code
in the drm-misc-next tree that might be causing a memory corruption.
It threw me off that the stack trace didn't contain anything related
to drm.

I have been on SLAB, I configured SLAB DEBUG with a fresh pull from github. Linux syzkaller 5.0.0-rc2 #9 SMP Sun Jan 13 21:57:40 EST 2019 x86_64
...

In an effort to get a different stack into the kernel, I felt that nothing works better than fork bomb? :)

Let me know if that helps.

And is test3 the same multi-threaded program that enters the kernel via
/dev/sg0 and then calls SCSI_IOCTL_SEND_COMMAND which goes to the SCSI
mid-level and thence to the block layer?

And please remind me, does it also fail on lk 4.20.2 ?

Yes, the same C repro from the earlier thread.  It was a 4.20.0 kernel where it was first detected.  I can move to 4.20.2 and see if that changes anything.

Hi,
I don't think there is any need to check lk 4.20.2 (as it would
be very surprising if it didn't also have this "feature").

More interesting might be: has "test3" been run on lk 4.19 or
any earlier kernel?

Re: [PATCH v2] rbtree: fix the red root

[Qian Cai]

Unfortunately, I could not trigger any of those here both in a bare-metal and
virtual machines. All I triggered were hung tasks and soft-lockup due to fork bomb.

The only other thing I can think of is to setup kdump to capture a vmcore when
either GPF or BUG() happens, and then share the vmcore somewhere, so I might
pork around to see where the memory corruption looks like.

Another question that I forgot to ask, what type of device is /dev/sg0 ?
On a prior occasion (KASAN, throw spaghetti ...) it was a SATA device
and the problem was in libata.

Another testing angle,

It might be something is doing __GFP_ZERO and overwriting those slabs. This also
matched the red root corruption, since RB_RED is bit 0.

One thing to try is to enable page_owner=on in the command-line, and then obtain
sorted_page_owner.txt before and after running the reproducer.

$ cd tools/vm
$ make page_owner_sort

$ cat /sys/kernel/debug/page_owner > page_owner_full.txt
$ grep -v ^PFN page_owner_full.txt > page_owner.txt
$ ./page_owner_sort page_owner.txt sorted_page_owner.txt

Re: [PATCH v2] rbtree: fix the red root

[Esme]

I have been off but back now, I had fetch'd current again and the diagnostics look a bit different, maybe I just got lucky.  Instead of fork'ng the test case (which is fairly aggressive in any case), interacting from the serial port with sig-int ^C tend's to trigger enough to hit something.  I'll get the page_owner sorted soon.

How I'm running;

qemu-system-x86_64 -kernel /home/files/dl/linux//arch/x86/boot/bzImage -append console=ttyS0 root=/dev/sda debug earlyprintk=serial slub_debug=QUZFP page_owner=on -hda stretch.img -net user,hostfwd=tcp::10021-:22 -net nic -enable-kvm -nographic -m 2G -smp 2

It's somewhat random I guess that in the last two CPU context dump's printed out, we see RAX and CR2 off by 4 from one another.

Instead of fork'ng the test case (which is fairly aggressive in any case), interacting from the serial port with sig-int ^C tend's to trigger enough to hit something.  I'll get the page_owner sorted soon.

While you are gathering page_owner (or kdump), it might be useful to use virtio
