Regression in 2.6.25-rc3: s2ram segfaults before suspending

Regression in 2.6.25-rc3: s2ram segfaults before suspending

[Klaus S. Madsen]

Hi all,

	I have a Thinkpad T61p, which I'm able to suspend with s2ram on
Linux 2.6.24.3. However when I try to suspend it on 2.6.25-rc3, s2ram
dies after changing to vt1, with a segfault. I'm using s2ram from cvs,
and libx86 version 0.99 from http://www.codon.org.uk/~mjg59/libx86/.

Some details about the segfault:

$ sudo gdb ./s2ram
(gdb) run
Starting program: /home/ksm/downloads/suspend/s2ram 
Switching from vt7 to vt1
Calling get_mode

Program received signal SIGSEGV, Segmentation fault.
0xb7facf4a in run_vm86 () at lrmi.c:526

(gdb) list
521     static int
522     lrmi_vm86(struct vm86_struct *vm)
523     {
524             int r;
525     #ifdef __PIC__
526             asm volatile (

528              "movl %2, %%ebx\n\t"
529              "int $0x80\n\t"
530              "popl %%ebx"
(gdb) bt

#5  0x0804954f in main (argc=1, argv=0x0) at s2ram-main.c:92

I have tried to bisect the problem, and it fingered the following
commit:

commit 82bc03fc158e28c90d7ed9919410776039cb4e14
Author: Ingo Molnar <mingo@elte.hu>

    x86: add PWT to NOCACHE flags

Reverting this commit in the bisected tree (by executing git show
82bc03fc158e28c90d7ed9919410776039cb4e14 | patch -R -p1), makes the
segfault go away. I've run make clean between each kernel compile, to be
sure the tree was correctly compiled.

I have attached the .config I'm using for 2.6.25-rc3 (when bisecting, I
just choose the default on every question). If necessary, I can try to
reconstruct the one I ended up with after the bisection.

Hope this makes sense to someone, and thanks in advance.

There's a known suspend problem with 2.6.25-rc3 that has been fixed already
in the Linus' tree.  Can you test the current head of the Linus' tree, please?

This does not look like known problem, actually... s2ram segfaults
somewhere in emulator...?

I've tested the head of Linus' git as of this morning, and the problem
still exists. Note however, that I don't even get to the suspend part,
as s2ram crashes before it initiates the kernel part of STR.

Yes, looks like ingo broke vm86 emulation, or something like that...?

I have attached my .config now, in case it's important.

thanks for tracking this down. It would be nice to figure out why this 
change made a difference. Perhaps VM86 mode has some restrictions in 
what type of pagetables it can operate in - and the CPU just refuses to 
properly emulate those 16-bit instructions? (this would be very weird). 
We are trying to execute 16-bit BIOS code here, right?

which instruction is the segfault coming from - the int $0x80? So in 
vm86 mode we generated a #GPF which shows up as a SIGSEGV?

I must say, that I don't quite understand why gdb fingers the "asm
volatile" line and not one of the assembly lines, when reporting the
segfault. But I'm not really well versed in lowlevel gdb use, so if you
could give me a about how I get gdb to disassemble the code at the
instruction pointer, I'll return with the result.

Thanks for taking the time to look at this.

typing 'disassemble' should do the trick.

If you have a specific address outside of the current instruction 
pointer, then doing disassembly on a range:

  disassemble 0xb7facf4a 0xb7facf8a

should work too.

The segfault was at address 0xb7f59f4a, and the disassembly of
the run_vm86 function is:

What this seems to indicate is a segfault inside VM mode that causes it 
to exit to deliver the SIGSEGV, so without more information, such as 
signal context, there isn't much to know about it.

It looks like the fault happens inside the VESA BIOS, specifically VBE 
function 3:

--------V-104F03-----------------------------
INT 10 - VESA SuperVGA BIOS - GET CURRENT VIDEO MODE
         AX = 4F03h
Return: AL = 4Fh if function supported
         AH = status
             00h successful
                 BX = video mode (see #00083,#00084)
                     bit 13: VBE/AF v1.0P accelerated video mode
                     bit 14: linear frame buffer enabled (VBE v2.0+)
                     bit 15: don't clear video memory
             01h failed
SeeAlso: AH=0Fh,AX=4E04h,AX=4F02h

... which normally would be a trivial function which only reads a couple 
of status words out of internal state and returns.

****

Typically, when the kernel reflects an error in VM86 mode it will update 
the structure in memory (in your case, the vm86plus_struct) to reflect 
the context.  Would it be possible for you to read it out?

[FWIW, that code looks like it's using assembly for no good current 
reason.  Not sure if it'd help to clean it up.]

Hmm. As far as I can tell, its actually using the vm86old system call?
That's at least what the comment in libx86 states.

However the contents of struct vm86_struct after the segfault is:

(gdb) print context.vm
$2 = {regs = {ebx = 0, ecx = 0, edx = 0, esi = 0, edi = 0, ebp = 0, 
    eax = 20227, __null_ds = 0, __null_es = 0, __null_fs = -1071579136, 
    __null_gs = 0, orig_eax = -1, eip = 6326, cs = 49152, __csh = 0, 
    eflags = 209410, esp = 4090, ss = 256, __ssh = 0, es = 0, __esh = 0, 
    ds = 64, __dsh = 0, fs = 0, __fsh = 0, gs = 0, __gsh = 0}, flags = 0, 
  screen_bitmap = 0, cpu_type = 0, int_revectored = {__map = {0, 0, 0,0, 0, 
      0, 0, 2147483648}}, int21_revectored = {__map = {0, 0, 0, 0, 0, 0, 0, 
      0}}}

My version of glibc does not seem to have vm86old declared, so I haven't
tried to remove the assembly code.

Should I try to change it to use vm86, instead of vm86old?

Yes, that would probably be a good idea.  To some degree, I guess it 
really has nothing to do with the more fundamental issue, but it's 
somewhat odd.

I'll pick apart the state above looking for fishiness as soon as I get 
back from lunch.

Ok. I tried changing the code from the assembly to do:

vm86(VM86_ENTER, vm)

instead. vm the vm86plus_struct structure fill in exactly the same way
as vm86_struct.

The output from GDB after the segfault is exactly the same as
previously, and all the fields in vm86plus_info_struct is zero.

This is the VGA BIOS being mapped, it's mapped PROT_READ|PROT_WRITE, but 
  no PROT_EXEC; if the kernel is NX-capable it *should* segfault trying 
to execute out of this area, which is exactly what will happen when vm86 
executes INT 10h.

If we can find that mmap() in the s2ram source code and add PROT_EXEC to 
it, it would be interesting.

Klaus, could you send your .config as well? Lets make sure that NX is 
even relevant in this context.

Allright. The mmap in question is in the x86-common.c file in libx86,
and adding PROT_EXEC to it solves the problem.

I have attached my .config.

The only thing I don't understand is why this is suddenly a problem with
2.6.25, and not with 2.6.24? Is there a bug in 2.6.24 and previously
that allows real-mode execution of non-executable pages?

One wonders, especially since the checkin it was bisected to it had 
nothing to do with NX.  I suspect there is either a bug in the NX logic, 
which this checkin inadvertently fixed(!), or there is an ad hoc hack 
that should probably never have existed.  More investigation necessary, 
but now we know a lot more.

Ok, sw should probably fix that in s2ram... can you mail a patch to
me, and suspend-devel?

It is strange indeed... Should it be traced as an regression?

As stated above, the problem is actually in libx86, and not in s2ram. I
have included Matthew Garrett in the CC list, as he's hosting the libx86
source code I have used as a base for my patch.

The following patch solves the segfault, by changing the mmap flags of
the video memory area, to allow execution. The patch is against
libx86-0.99 available from http://www.codon.org.uk/~mjg59/libx86/

I honestly don't know. From hpa's comments, it seems as is the segfault
would be the expected behaviour, but as 2.6.24 and previously doesn't
segfault, I guess it's a matter of determining if the original
non-segfaulting behaviour is by design, or a bug.

are you sure you ID-ed the right commit that broke things?

while requiring PROT_EXEC is fine, breaking existing user-space apps 
over that is not fine. So are you absolutely sure that by reverting that 
PWT|PCD commit, s2ram again starts to work? That's utmost weird...

perhaps there's some CPU bug that causes NX to _NOT_ work if only PCD is 
used (not PCD|PWT). Seems like a pretty unlikely scenario though.

It really does.  What would be much more likely is that the PCD -> 
(PCD|PWT) triggered something in the kernel proper.

I can't be sure. It was my third attempt, and there seems to be some
sort of Makefile trouble in that area, which causes the problem to
appear and disappear at random, unless I do a make clean && make. But
the triggering commit was found with make clean && make, and I made sure
that reverting the resulting commit did actually solve the problem...

However I wasn't able to make the problem go away, by removing the
_PAGE_PWT constants from __PAGE_KERNEL_NOCACHE and
__PAGE_KERNEL_VSYSCALL_NOCACHE in include-asm/pgtable.h in the newest
2.6.25:

diff --git a/include/asm-x86/pgtable.h b/include/asm-x86/pgtable.h
index 174b877..f81c968 100644
--- a/include/asm-x86/pgtable.h
+++ b/include/asm-x86/pgtable.h
@@ -84,9 +84,9 @@ extern pteval_t __PAGE_KERNEL, __PAGE_KERNEL_EXEC;

 #define __PAGE_KERNEL_LARGE		(__PAGE_KERNEL | _PAGE_PSE)
 #define __PAGE_KERNEL_LARGE_EXEC	(__PAGE_KERNEL_EXEC | _PAGE_PSE)
 
So while I'm fairly confident in that I bisected correctly, the number
of attempts I had to go through to get a reliable result, and the fact
that I cannot make the problem go away by reverting the current code to
something similar, counts quite a lot against me.

However I'm 100% confident that the problem appears between
cf8fa920cb4271f17e0265c863d64bea1b31941a and
925596a017bbd045ff711b778256f459e50a119, which is something like 16
commits. I have been at both points in the tree at least 2 times, and
confirmed that cf8fa920cb4271f17e0265c863d64bea1b31941a worked for me,
and 925596a017bbd045ff711b778256f459e50a119 didn't.

I'm sure that it fixed the problem for me, yes, and I'm fairly confident
that I ran make clean && make to compile the kernel during the entire
bisection between the two commites mentioned above.

I do not have NX capable CPU in machine using for suspend

Sorry, I meant "32-bit userspace on 32-bit kernel"... but that on
64-bit capable cpu.

Yes. With 4 GB of RAM, so I use PAE, which is also required for NX. Just
to be sure, I disabled PAE, and sure enough, the problem disappeared.
 
I'll double that the commit I fingered actually caused the problem, but
I will not have time for this before tomorrw evening. 

Just to be sure: If I want to checkout the revision, just before the bad
commit I can do something like:

git checkout commit-id~1

Right? 

Thanks for spending time on this.

my guess would be that it's this commit that causes it:

PAE activates NX on 32-bit. So we probably had an NX regression that got 
fixed by the side-effects of one of the unifications. Does it start 
working if you disable NX via the noexec=off boot option?

All right. I just tried the following:

git checkout 82bc03fc158e28c90d7ed9919410776039cb4e14
make clean && make -j3 && sudo make install modules_install

And the resulting kernel works OK. However if I checkout commit
6c3866558213ff706d8331053386915371ad63ec, and compile it using the
previous commandline, s2ram fails so it seems you're right.

If I boot with noexec=off, s2ram starts working again.

What's the state of play here?  Is upshot that this change fixed a bug 
which broke s2ram, or caused a bug which broke s2ram?

As far as I can tell, this change fixed a bug, and the fact that the bug 
was fixed triggered a s2ram bug.

OK.  Doesn't surprise me.  There were a few cases of dubious pte

Strictly a libx86 bug, so I'll try to get an updated version uploaded in 
the near future. This won't hit x86_64 users, since the code is run 
through x86emu rather than executed directly.

btw., even if it turns out to be the wrong commit, you sure poked in the 
right general area. This is one of the reoccuring problems with git 
bisection: a small mistake near the end of a long bisection session can 
point to the wrong commit. Especially with more sporadic failure modes 
it can be quite a challenge.

I'm tracing it FWIW.  However, it would be good to know if all of the previous
kernels were buggy and 2.6.25 fixed the problem or it's the other way around.

I'd like to understand what the heck happened, but as far as we can 
observe right now, it's a *progression*, not a regression, since 
executing out of a non-PROT_EXEC area isn't *supposed* to work...

Okay, I guess this depends on the eye of the beholder... because s2ram
*is* supposed to work ;-).

Ideally, I'd like to keep 2.6.24 behaviour for at least a while, so we
can try to fix the libx86 out there or something...

Allowing execution of a PROT_EXEC area is a security hole.  The fact 
that you happened to benefit from it doesn't change its nature as a 
security hole.

if s2ram worked before, and breaks with v2.6.25 then it's a regression. 
It doesnt really matter that this segfault is the right thing to do ...

what would be _really_ nice to know how this all links up to the PCD -> 
PCD|PWT commit. I.e. how did the commit below suddenly _trigger_ this 
segfault? Are we absolutely sure that the bisection is correct, that 
it's this commit which broke things? [i.e. if this commit is unapplied, 
does s2ram work?]

there are a few "nearby" commits in the bisection tree:

I'm sorry, I have to disagree with this one, simply because it's a 
security model violation.  We can't just say "well, app X does this even
