[PATCH] jump_label: align jump_entry table to at least 4-bytes

[PATCH] jump_label: align jump_entry table to at least 4-bytes

[Jason Baron]

The core jump_label code makes use of the 2 lower bits of the
static_key::[type|entries|next] field. Thus, ensure that the jump_entry
table is at least 4-byte aligned.

I will speak only for the MIPS part.

If the section is not already properly aligned, this change will add 
padding, which is probably not what we want.

Have you ever seen a problem with misalignment in the real world?

If so, I think a better approach might be to set properties on the 
__jump_table section to force the proper alignment, or do something in 
the linker script.

Hi,

Yes, there was a WARN_ON() reported on POWER here:

https://lkml.org/lkml/2017/2/19/85

The WARN_ON() triggers if either of the 2 lsb are set. More 
specifically, its coming from 'static_key_set_entries()' from the 
following patch, which was recently added to linux-next:

https://lkml.org/lkml/2017/2/3/558

So this was not seen on mips, but I included all arches in this patch 
that I though might be affected.

So in include/asm-generic/vmlinux.lds.h, we are already setting 
'ALIGN(8)', but that does not appear to be sufficient for POWER...

Also, I checked the size of the vmlinux generated after this change on 
all 4 arches, and it was rather minimal. I think POWER increased the 
most, but the other arches increased by only a few bytes.

Thanks,

Yes, I just looked at that.  The ALIGN(8), combined with the fact that 
on MIPS, WORD_INSN will always be of size 4 or 8 (32-bit vs. 64-bit 
kernel), seems to make any additional .balign completely unnecessary.


Really, I think you need to figure out why on powerpc the alignments are 
getting screwed up.  The struct jump_entry entries are on a stride of 12 
(for a 32-bit kernel) or 24 (for a 64-bit kernel), any alignment padding 
added by .balign 4 will surely screw that up.

This patch seems like it is papering over a bigger issue that is not 
understood.

I think a proper fix would be to fix whatever is causing the powerpc 
JUMP_ENTRY_TYPE to misbehave.

For me the size is not the important issue, it is the alignment of the 
struct jump_entry entries in the table.  I don't understand how your 
patch helps, and I cannot Acked-by unless I understand what is being 
done and can see that it is both correct and necessary.

You brought up a very good point and I'm glad that I had Jason Cc all
the arch maintainers in one patch.

I think jump_labels may be much more broken than we think, and Jason's
fix doesn't fix anything. We had this same issues with tracepoints.

I'm looking at jump_label_init, and how we iterate over an array of
struct jump_entry's that was put together by the linker. The problem is
that jump_entry is not a power of 2 in size.

struct jump_entry {
	jump_label_t code;
	jump_label_t target;
	jump_label_t key;
};

When putting together arrays of this kind, the linker is in its right
to add padding for alignment, in the middle of the array! It has no
idea that this is an array, and there's nothing stopping the linker
from messing it up.

For those structs that are a power of 2 in size, there's no reason for
the linker to do anything else, and it "just works". There's plenty of
instances in the kernel that depend on this.

I'm thinking that the sort algorithm either hid the problem or fixed it
somehow (I'm guessing it hid the problem).

I hit the same issue with trace event structures. The solution was to
create the array of pointers to each structure, and dereference the
structures from the array.

See commit e4a9ea5ee ("tracing: Replace trace_event struct array with
pointer array")

ELF sections may have an ENTSIZE property exactly for arrays.  Since 
each jump_entry will have a unique value they cannot be merged, but we 
can tell the assembler they are an array and get them properly packed. 
Perhaps something like (untested):

    .pushsection __jump_table,  \"awM\",@progbits,24
    FOO
    .popsection

See attached for mips.  It seems to do the right thing.

I leave it as an exercise to the reader to fix the other architectures.

Consult your own  binutils experts to verify that what I say is true.

Subject: [PATCH] MIPS: jump_lable: Give __jump_table elements an entsize.

Since the __jump_table is a big array of non power-of-2 sized
elements, tell the linker the size so they can be properly packed.
Since each element will have unique "code" and "key" fields, no
merging will ever occur, but it should end up properly packed.

See attached for mips.  It seems to do the right thing.

I leave it as an exercise to the reader to fix the other architectures.

Consult your own  binutils experts to verify that what I say is true.

It may still just be safer to do the pointers instead. That way we
don't need to worry about some strange arch or off by one binutils
messing it up.

Obviously it is your choice, but this is bog standard ELF linking.  In 
theory even the arrays of power-of-2 sized objects should also supply an 
entity size.  Think __ex_table and its ilk.


The benefit of supplying an entsize is that you don't have to change the 
structure of the existing code and risk breaking something in the process.

Thanks for the suggestion! I would like to see if this resolves the ppc 
issue we had. I'm attaching a powerpc patch based on your suggestion. 
Hopefully, Sachin can try it.

If there are problems, you could try something like:


$ find . -name \*\.o | xargs mips64-octeon-linux-gnu-readelf -eW  | grep 
'File:\| __jump_table'
File: ./drivers/firmware/built-in.o
File: ./drivers/built-in.o
   [3249] __jump_table      PROGBITS        0000000000000000 1838c8

File: ./drivers/spi/spi-cavium-octeon.o
File: ./drivers/spi/spi-cavium.o

.
.

Look for files where the size of the __jump_table section is not a 
integer multiple of the entsize.

Those look good to me 18/18 = 1 with no remainder.  The odd numbers are 
the offset of the section in the ELF file.

If you look at the stack trace, it seems that it is during module loading.

Are the primitives for generating the tables doing something different 
for the module case?  I am not familiar enough with the powerpc ABIs to 
know.

Try this:

$ perl -n -e 's/\[ /\[/; my @f = split " "; print hex($f[5]) % 0x18 if 
$#f > 5; print $_' <~/jump_table.log


There are no entries with size that is not a multiple of 0x18.

I think my patch to add the ENTSIZE is not doing anything here.

I suspect that the alignment of the __jump_table section in the .ko 
files is not correct, and you are seeing some sort of problem due to that.

Hi,

Yes, if you look at the trace that Sachin sent the module being loaded 
that does the WARN_ON() is nfsd.ko.

That module from Sachin's trace has:

18 WAM  0   0  1

So its not the size but rather the start offset '03fd77', that is the 
problem here. That is what the WARN_ON triggers on, that the start of 
the table is not 4-byte aligned.

Using a ppc cross-compiler and the ENTSIZE patch that line does not 
change, however if I use the initial patch posted in this thread, the 
start does align to 4-bytes and thus the warning goes away, as Sachin 
verified. In fact, without the patch I found several modules that don't 
start at the proper alignment, however with the patch that started this 
thread they were all properly aligned.

In terms of the '.balign' causing holes, we originally added the 
'_ASM_ALIGN' to x86 for precisely this reason. See commit:
ef64789 jump label: Add _ASM_ALIGN for x86 and x86_64 and discussion.

In addition, we have a lot of runtime with the .balign in the tree and 
I'm not aware of any holes in the table. I think the code would blow up 
pretty badly if there were.

A number of arches were already using the '.balign', and the patch I 
proposed simply added it to remaining ones, now that we added a 
WARN_ON() to catch this condition.

Hi,

Yes, if you look at the trace that Sachin sent the module being loaded 
that does the WARN_ON() is nfsd.ko.

That module from Sachin's trace has:

   [31] __jump_table      PROGBITS        0000000000000000 03fd77 0000c0 
18 WAM  0   0  1

So its not the size but rather the start offset '03fd77', that is the 
problem here. That is what the WARN_ON triggers on, that the start of 
the table is not 4-byte aligned.

Using a ppc cross-compiler and the ENTSIZE patch that line does not 
change, however if I use the initial patch posted in this thread, the 
start does align to 4-bytes and thus the warning goes away, as Sachin 
verified. In fact, without the patch I found several modules that don't 
start at the proper alignment, however with the patch that started this 
thread they were all properly aligned.

In terms of the '.balign' causing holes, we originally added the 
'_ASM_ALIGN' to x86 for precisely this reason. See commit:
ef64789 jump label: Add _ASM_ALIGN for x86 and x86_64 and discussion.

In addition, we have a lot of runtime with the .balign in the tree and 
I'm not aware of any holes in the table. I think the code would blow up 
pretty badly if there were.

A number of arches were already using the '.balign', and the patch I 
proposed simply added it to remaining ones, now that we added a 
WARN_ON() to catch this condition.

The problem is then the section alignment (last column) for power.

On mips with no patches applied, we get:

   [17] __jump_table      PROGBITS        0000000000000000 00d2c0 000048 
00  WA  0   0  8

Look, proper alignment!

The question I have is why do the power ".llong" and ".long" assembler 
directives not force section alignment?  Is there an alternative that 
could be used that would result in the proper alignment?  Would ".word" 
work?

If not, then I would say patch only power with your balign thing.

I think the proper fix is either:

A) Modify scripts/module-common.lds to force __jump_table alignment for 
all architectures.

B) Add arch/powerpc/kernel/module.lds to force __jump_table alignment 
for powerpc only.

Ok, I can try adding it to the linger script.

FWIW, here is my before and after with the .balign thing for the nfsd.ko
module on powperc (using a cross-compiler):

before:

  [31] __jump_table      PROGBITS        0000000000000000 03ee3e 0000f0
00  WA  0   0  1

after:

 [31] __jump_table      PROGBITS        0000000000000000 03ee40 0000f0
00  WA  0   0  4

Thanks,

Ok, I can try adding it to the linger script.

FWIW, here is my before and after with the .balign thing for the nfsd.ko
module on powperc (using a cross-compiler):

before:

  [31] __jump_table      PROGBITS        0000000000000000 03ee3e 0000f0
00  WA  0   0  1

after:

 [31] __jump_table      PROGBITS        0000000000000000 03ee40 0000f0
00  WA  0   0  4

Thanks,

-Jason

Subject: [PATCH] module: set __jump_table alignment to 8

For powerpc the __jump_table section in modules is not aligned, this
causes an OOPS when loading a module containing a __jump_table.

Fix by forcing __jump_table to 8, which is the same alignment used for
this section in the kernel proper.

So before your module.lds script:

# powerpc64-linux-readelf -eW fs/nfsd/nfsd.o | grep jump 

   [31] __jump_table      PROGBITS        0000000000000000 03edfe 0000f0 
00  WA  0   0  1
 

# powerpc64-linux-readelf -eW fs/nfsd/nfsd.ko | grep jump 

   [32] __jump_table      PROGBITS        0000000000000000 044046 0000f0 
00  WA  0   0  1

With your patch:
 
 
 

# powerpc64-linux-readelf -eW fs/nfsd/nfsd.o | grep jump 

   [31] __jump_table      PROGBITS        0000000000000000 03edfe 0000f0 
00  WA  0   0  1
 

# powerpc64-linux-readelf -eW fs/nfsd/nfsd.ko | grep jump 

   [18] __jump_table      PROGBITS        0000000000000000 03e358 0000f0 
00  WA  0   0  8


I also checked all the other .ko files and they were properly aligned. 
So I think this should hopefully work, and I like that its not a 
per-arch fix.

Sachin, sorry to bother you again, but I'm hoping you can try David's 
latest patch to scripts/module-common.lds, just to test in your setup.

So before your module.lds script:

# powerpc64-linux-readelf -eW fs/nfsd/nfsd.o | grep jump 

   [31] __jump_table      PROGBITS        0000000000000000 03edfe 0000f0 
00  WA  0   0  1
 

# powerpc64-linux-readelf -eW fs/nfsd/nfsd.ko | grep jump 

   [32] __jump_table      PROGBITS        0000000000000000 044046 0000f0 
00  WA  0   0  1

With your patch:
 
 
 

# powerpc64-linux-readelf -eW fs/nfsd/nfsd.o | grep jump 

   [31] __jump_table      PROGBITS        0000000000000000 03edfe 0000f0 
00  WA  0   0  1
 

# powerpc64-linux-readelf -eW fs/nfsd/nfsd.ko | grep jump 

   [18] __jump_table      PROGBITS        0000000000000000 03e358 0000f0 
00  WA  0   0  8


I also checked all the other .ko files and they were properly aligned. 
So I think this should hopefully work, and I like that its not a 
per-arch fix.

Sachin, sorry to bother you again, but I'm hoping you can try David's

It does fix the problem.

I was reproducing with crc_t10dif:

[  695.890552] ------------[ cut here ]------------
[  695.890709] WARNING: CPU: 15 PID: 3019 at ../kernel/jump_label.c:287 static_key_set_entries+0x74/0xa0

Which had:

  [21] __jump_table      PROGBITS        0000000000000000 0004e8 000018 00  WA  0   0  1


And now has:

  [18] __jump_table      PROGBITS        0000000000000000 0004d0 000018 00  WA  0   0  8

And all other modules have an alignment of 8 on __jump_table, as expected.

I'm inclined to merge a version of the balign patch for powerpc anyway,
just to be on the safe side. I guess the old code was coping fine with
the unaligned keys, but it still makes me nervous.

cheers

[  695.890552] ------------[ cut here ]------------
[  695.890709] WARNING: CPU: 15 PID: 3019 at ../kernel/jump_label.c:287 static_key_set_entries+0x74/0xa0

Which had:

  [21] __jump_table      PROGBITS        0000000000000000 0004e8 000018 00  WA  0   0  1


And now has:

  [18] __jump_table      PROGBITS        0000000000000000 0004d0 000018 00  WA  0   0  8

And all other modules have an alignment of 8 on __jump_table, as expected.

I'm inclined to merge a version of the balign patch for powerpc anyway,
just to be on the safe side. I guess the old code was coping fine with
the unaligned keys, but it still makes me nervous.

cheers

The original "balign patch" has a couple of problems:

1) 4-byte alignment is not sufficient for 64-bit kernels

2) It is redundant if the linker script patch is accepted.

The linker script patch seems reasonable to me.

Maybe its worth adding a comment that the alignment is necessary because
the core jump_label makes use of the 2 lsb bits of its __jump_table
pointer due to commit:

3821fd3 jump_label: Reduce the size of struct static_key

Also, in the comment it says that it fixes an oops. We hit a WARN_ON()
not an oops, although bad things are likely to happen when the branch is
updated.

Thanks,

I tested the patch on 2 different systems where I ran into this problem. In both cases
the system boots without any warning. A quick module load/unload test also worked
correctly.

I agree that this may be the better answer. The issue tracepoints had
is that they were defined in C with a "section" attribute. I'm not sure
you can pass various section attributes via a gcc section attribute.

[PATCH] MIPS: jump_lable: Give __jump_table elements an entsize.

[David Daney]

Since the __jump_table is a big array of non power-of-2 sized
elements, tell the linker the size so they can be properly packed.
Since each element will have unique "code" and "key" fields, no
merging will ever occur, but it should end up properly packed.
