Discussion:
Linker Bug or Design Intent (Absolute symbols in zero sized sections)
(too old to reply)

Hi,

I got a query. Ld behaviour does not seem to be conforming to what is
mentioned in "info ld"

I was going through the info ld and found following in the section 3.6.7
"Output Section Discarding"

"If you use anything other than an input section description as an
output section command, such as a symbol assignment, then the output
section will always be created, even if there are no matching input
sections."

I am compiling my kernel and I don't seem to be getting above mentioned
behaviour. For, example vmlinux.ld.S has got following code.

.smp_altinstructions : AT(ADDR(.smp_altinstructions) - LOAD_OFFSET) {
__smp_alt_begin = .;
__smp_alt_instructions = .;
*(.smp_altinstructions)
__smp_alt_instructions_end = .;
}


In finally generated executable, thre is no section as
.smp_altinstructions and symbols __smp_alt_begin, __smp_alt_instructions
and __smp_alt_instructions_end have become absolute symbols.

Looks like there was no section .smp_altinstructions present in input
files hence linker did not create output section and made symbols
absolute. This does not match the behaviour as stated in "info ld". Is
this a bug or design intent?

I am using GNU ld version 2.17.50.0.3-1

HOW AM I IMPACTED:
--------------------

Now we are trying to make i386 kernel fully relocatable. We compile the
kernel with option --emit-relocs and use this relocation information to
relocate the kernel at run time. But as per the specifications absolute
symbols are not to be relocated.

Now, above compiler makes some symbols absolute and these symbols are
not relocated and kernel code fails at some point. In this case kernel
fails because it is trying to free memory between symbol __smp_alt_begin
and another symbol present in other section. __smp_alt_begin is now
absolute and does not get relocated and kernel ends up trying to free a
wrong portion of memory.

Do you have any thoughts about what's the right way of fixing the issue?
Its a linker bug or it should be fixed in kernel?

Thanks

Why do you want to free a memory which doesn't exist?

Well, based on various CONFIG options, some init sections might be
created when kernel is compiled. Memory belonging to these sections is
freed once initialization is over.

In the above case, kernel defines following three sections in ld script
and tries to free up memory __smp_alt_being and __smp_alt_end. From a
programming perspective one can always do.

If (__smp_alt_being < __smp_alt_end)
Free up memory;



.smp_altinstructions : AT(ADDR(.smp_altinstructions) - LOAD_OFFSET) {
__smp_alt_begin = .;
__smp_alt_instructions = .;
*(.smp_altinstructions)
__smp_alt_instructions_end = .;
}
. = ALIGN(4);
.smp_locks : AT(ADDR(.smp_locks) - LOAD_OFFSET) {
__smp_locks = .;
*(.smp_locks)
__smp_locks_end = .;
}
.smp_altinstr_replacement : AT(ADDR(.smp_altinstr_replacement) -
LOAD_OFFSET) {
*(.smp_altinstr_replacement)
. = ALIGN(4096);
__smp_alt_end = .;
}

I think for --emit-relocs, we can keep an empty output section if its
address is taken.

Of course, we need to update linker doc.

I think we're being too specific to this case.

Why are we changing what the linker script clearly defines as section
relative symbols to absolute symbols? This isn't the only use case
I've encountered where that will break. We should either discard the
symbols, or leave the empty section.

I think retaining the zero sized section might be more logical otherwise
a user who has specifically defined a section relative symbol in linker
script file will be surprised to know that in some cases symbol is not
present at all.

I think removing empty output sections isn't a bad idea. Otherwise,
a normal executable/DSO may have many empty output sections since
the default linker scripts may have many unused output sections.

However, I agree that removing empty output sections shouldn't lead
to many surprises for user. I think linker

1. Should remove an empty output section if it isn't used to define
section relative symbol which may be changed at run time.
2. Shouldn't convert a section relative symbol to absolute symbol
if it may be changed at run time.
3. Should preserve the pre-set constant VMA of an empty output section.

Is there anything I missed?

I think if we just stick to the behaviour as described in "info ld" that
should be good enough. So linker will get rid of zero sized sections
except in following situation.

3.6.7 Output Section Discarding
-------------------------------

"If you use anything other than an input section description as an
output section command, such as a symbol assignment, then the output
section will always be created, even if there are no matching input
sections."

Convert section relative symbol to absolute shouldn't be a problem
in most cases. If we know it may be a problem at link time, we can
keep it section relative.

I need --emit-relocs as it retains the relocation information in finally
linked executable and I use that relocation information to relocate the
image to a different address at run time. It is just a matter of going
through all the relocation entries and adding an offset value.

Sorry I don't understand the first question very well. The moment a
symbol is section relative and if section is moved at run time, I will
be walking through and procesing all the relocations generated wrt to
that symbol at run time.

You keep saying this, but on various platforms it isn't true. Section
relative symbols move with an object if it is relocated in any way.
Absolute symbols don't. So, for instance any application which reads
the symbol table of a shared library can tell the difference.

And there are plenty of known platforms (e.g. Windows, SymbianOS,
VxWorks) where the distance between segments changes at load time,
so converting a relative symbol into an absolute one makes it useless;
we must be able to figure out which segment it was relative to.

Absolute symbols don't.
This isn't true for the common ELF targets. An absolute symbol in a
shared library is effectively relative to the base of the shared lib.
A sad consequence of defining syms like _GLOBAL_OFFSET_TABLE_ and
_DYNAMIC as absolute.

Which I tried to change, you may recall :-) For those platforms which
do care, absolute _G_O_T_ is a serious problem, and there's a knob for
it.

But what benefit is there in converting symbols from relative to

I have checked in a patch not to remove an empty section if there is

This has an ugly drawback that now almost every executable has
[15] .preinit_array PREINIT_ARRAY 0000000010010a94 010a94 000000 00 WA 0 0 1
[16] .init_array INIT_ARRAY 0000000010010a94 010a94 000000 00 WA 0 0 1
[17] .fini_array FINI_ARRAY 0000000010010a94 010a94 000000 00 WA 0 0 1
Can't we at least come up with PROVIDES/PROVIDES_HIDDEN variants that would
allow these symbols turned into absolute and/or to absolute 0 if the
section is empty and not output such empty sections and use that in the
builtin linker script?

It is nice kernel can now do its dirty hacks, but the userland shouldn't
suffer because of that.

and prelink isn't exactly excited about such sh_offset jumps here and
there. This patch adds a REMOVE_EMPTY output section flag which
when present in the linker script basically undoes the PR ld/3223
changes for that section, so if the section is empty and there are any
symbols defined in it, they are changed into absolute ones.
For .preinit_array/.init_array/.fini_array libc certainly won't mind
that, if the start and end symbols are equal, it won't do anything, no
matter what values those symbols have.

On ppc, I'm still getting zero size .sdata.
Here we have:
.sdata :
{
PROVIDE (_SDA_BASE_ = 32768);
*(.sdata .sdata.* .gnu.linkonce.s.*)
}
Either we could add here REMOVE_EMPTY flag, or, perhaps better, not consider
at least symbol = absolute value assignments as section relative,
so adding something like:
&& tree->assign.src->type.node_class != etree_value
to the tests that check if section_relative_symbol should be set.

Sections containing symbols really do need to stay, for --emit-relocs
and dynamic relocs. Or at least, we need to do something to make them
work properly.
Dynamic relocs aren't an issue here, in both cases we are talking about
executables and the the __{{pre,}init,fini}_array_{start,end} symbols
are PROVIDE_HIDDEN and __SDA_BASE__ likely should be PROVIDE_HIDDEN too
(and, furthermore for __SDA_BASE__ using section relative symbol is wrong,
as it is assigned a constant value, unrelated to the current section
(and in any case tweaked by the ppc backend; if there is non-empty
.sdata, __SDA_BASE__ is even ABS, only when it is empty it is section
relative ATM)). For --emit-relocs and the init/fini array symbols
we again don't care what exact values they have, as long as a post-linking
tool doesn't want to add things into one of the previously empty
.init_array etc. sections. But, such tool either would need to be
aware what these symbols mean and set them properly after inserting
stuff there, the *_array_start one to the beginning of the section and
*_array_end to the end of the section, or it would do the wrong thing
(kept either both symbols at the beginning, or end of the section it
grew, in any case for the _start code this would mean there is no such
section).

Against emitting empty sections speaks both that it is a wasted space
in section header table/.shstrtab, but more importantly that empty
sections are an endless source of bugs (as shown yesterday e.g.
on x86-64) in almost every tool that needs to deal with them.
This is not the first time ld didn't get sh_offsets for empty sections
right, I remember fighting with that several times in prelink, strip/objcopy
was messing them up in the past too and prelink had bugs in handling them
too.

Dynamic relocs aren't an issue here
Well, yes, but they are a problem in other sections when building shared
libs. I'd like to see a general solution rather than a hack that only
works for some sections.

Agreed.

If we are to remove them, then
a) Detecting a symbol assignment in a linker script should result in the
section alignment and vma being honoured.
b) All the ELF backends will need changes so that removed output section
syms are never used when emitting relocs. At the same time, we may
as well just use one section sym for all relocs (or two for targets
that might want to relocate the data segment separately from the text
segment).
c) _bfd_fix_excluded_sec_syms should be changed to not create absolute
syms.

Comments?

Something like that. I figured on just using the closest preceding
section. BTW, I started throwing a patch together to do (b).

This patch does all of the above, plus adjusts the ld testsuite for
the changes. A number of ELF targets will now use no dynamic section
symbols while others will just use one (or two when TLS is involved).
I started looking at FRV, and decided to leave the dyn sym change to a
target maintainer because it seemed likely to me that I'd break
something.. I also won't commit the S+core patch included here until
I get the OK from Mei Ligang; It changes elf32-score.c to use the
zero index symbol on dynamic relocations rather than use section
symbols. This is desirable on a new target as it should speed ld.so
slightly, but of course the dynamic linker support needs to be
available.

a) Detecting a symbol assignment in a linker script should result in the
section alignment and vma being honoured.
b) All the ELF backends will need changes so that removed output section
syms are never used when emitting relocs. At the same time, we may
as well just use one section sym for all relocs (or two for targets
that might want to relocate the data segment separately from the text
segment).
c) _bfd_fix_excluded_sec_syms should be changed to not create absolute
syms.
This patch does all of the above, plus adjusts the ld testsuite for
the changes. A number of ELF targets will now use no dynamic section
symbols while others will just use one (or two when TLS is involved).
I started looking at FRV, and decided to leave the dyn sym change to a
target maintainer because it seemed likely to me that I'd break
something.. I also won't commit the S+core patch included here until
I get the OK from Mei Ligang; It changes elf32-score.c to use the
zero index symbol on dynamic relocations rather than use section
symbols. This is desirable on a new target as it should speed ld.so
slightly, but of course the dynamic linker support needs to be
available.
It is OK.

Thanks a lot for this, seems to work fine here.

Only a minor nit, IMHO using the preceeding section isn't always
the best choice. E.g. .init_array etc. sections usually start the
RW segment (unless there is .tdata or .tbss) and those are often zero sized,
yet contain __init_array_{start,end} etc. symbols. With current CVS
binutils those symbols are attached to the preceeding section, which
is typically in the RX segment many KBs/MBs away, while there is
usually a section right after the removed .init_array which is kept.
The following patch prefers to use the next section if symbol's value
is not within the preceeding section (or equal to its end) and if
there is a following section that starts at vma equal to symbol value.
Is this ok for trunk or do you prefer to always choose the preceeding
section?

Hmm. I prefer something different. :-) What we really want is to
choose a section in the same segment as the removed section would
have been if it was kept. Also, I think it a good idea to avoid
changing a symbol from a TLS section to non-TLS and vice versa.
We can make a reasonable guess about section to segment mapping from
the section flags.

section based on section flags and vma.

If we remove the section shouldn't we also remove the symbol?
The idea was to support a script like the following. When .data is
empty and removed, you might still want __data_start defined. The
user has defined __data_start in .data because he wants the start
sym adjusted for any alignment that might occur due to input .data
section alignment.

.data :
{
__data_start = .;
*(.data)
}
.data2 :
{
*(.data2)
}
__data_end = .;

Of course, we need to update linker doc.

It looks like we shouldn't convert section relative symbols in linker
script to absolute symbol. We still need to do decide if/how we should
remove an empty section which doesn't have a symbol relative to it.

1. If the empty section doesn't set VMA, removing it doesn't change
the next section VMA.
2. If its VMA is set to a constant, removing it will change the next
section VMA.
3. If its VMA is set to an expression, removing it may change the next
section VMA.

I'd like to totally remove the empty section and set the next section
VMA to "dot" for #1 and #3. For #2, we remove the empty section and
set to the next section VMA to the constant VMA of the removed empty
section.
