[Bug binutils/14493] New: "strip" breaks .SUNW_ldynsym section on illumos
http://sourceware.org/bugzilla/show_bug.cgi?id=14493
Bug #: 14493
Summary: "strip" breaks .SUNW_ldynsym section on illumos
Product: binutils
Version: 2.22
Status: NEW
Severity: normal
Priority: P2
Component: binutils
AssignedTo: unassig...@sourceware.org
ReportedBy: pashev.i...@gmail.com
Classification: Unclassified
Created attachment 6586
--> http://sourceware.org/bugzilla/attachment.cgi?id=6586
test_ldynsym-nonstripped-elfdump-s.txt
"strip" damages ELF section ".SUNW_ldynsym" on illumos.
As a result elfdump reports, for example, "libavl.so.1: .SUNW_ldynsym: invalid
sh_link: 0"
And linker cannot link with the resulting library:
"ld: fatal: file libc.so: section [4279087549](null): has invalid sh_info:
-37933168108576"
Here is a minimal example from [1]:
#include
static void
static_func(void)
{
/* Use dladdr(3C) to print a call stack */
printstack(1);
/*
* Write to address 0, killing the process and
* producing a core file.
*/
*((char *) 0) = 1;
}
int main(int argc, char *argv[])
{
static_func();
return (0);
}
# cc -Wl,-znoldynsym test.c -o test_noldynsym
# cc test.c -o test_ldynsym

# strip test_noldynsym
# elfdump -s test_noldynsym > test_noldynsym-stripped-elfdump-s.txt
Also, before stripping size of test_ldynsym is 10K, after - 72K(!)

[Bug ld/13406] version script: please allow anonymous tag to be combined with other tags
http://sourceware.org/bugzilla/show_bug.cgi?id=13406
--- Comment #4 from Igor Pashev 2012-11-09
18:56:08 UTC ---
anonymous tag may not be combined with other tags.
Instead, on Solaris platform, any non-tagged symbol must be tagged with "Base
version": soname or file base name (if no soname)
https://github.com/illumos/illumos-gate/blob/master/usr/src/cmd/sgs/libld/common/version.c#L948
So if libfoo.so.2 has such a mapfile:
{
global:
foo_hello;
foo_world;
}
it must be read as:
libfoo.so.2 {
global:
foo_hello;
foo_world;
}

--- Comment #14 from Igor Pashev 2012-11-13

I think I've fixed this.
The root of the problem is equivalent to this version script:
= >8
# "Builtin":
{
global:
_PROCEDURE_LINKAGE_TABLE_;
_edata;
...
}
# Real mapfile:
{
...
}
= 8<
So for anonymous version tag we just set base version: (See patch)
Test:
# cat test.c
int foo()
{
return 17;
}
const char *bar()
{
return "bar";
}
# cat map
{
global:
foo;
local:
bar;
};
# gcc -fpic -c test.c -o lib.o -O0
# ld/ld-new -o lib.so lib.o -shared --version-script=map
# objdump -T lib.so

[Bug ld/14852] New: gnu ld can't use a library linked via solaris ld, if that library uses a library linked with GNU ld
http://sourceware.org/bugzilla/show_bug.cgi?id=14852 Bug #: 14852 Summary: gnu ld can't use a library linked via solaris ld, if that library uses a library linked with GNU ld Product: binutils Version: 2.22 Status: NEW Severity: normal Priority: P2 Component: ld AssignedTo: unassig...@sourceware.org ReportedBy: pashev.i...@gmail.com Classification: Unclassified Created attachment 6741 --> http://sourceware.org/bugzilla/attachment.cgi?id=6741 test suite and binaries Suppose we have a library [number 1] linked with GNU ld, say libz. Then we use this library (libz) to create other library [number 2] (e. g. libzfs), but using illumos/solaris link-editor. Then if we try to link libzfs to some application using GNU ld we will fail. Error will look like: "undefined reference to `compr...@libz.so.1'" This is because symbol `compress' in libz has no version assosiated, and thus is of "base version" which is the soname. Default and hardcoded behavior of solaris link-editor is to import base versions into outputfile (I quess it is like the option --default-imported-symver for GNU ld). I'd rather think it's solaris linker bug (a kind of), but it looks more tricky, because solaris linker can use library number 2 without any issues. I'm attaching an archive with tests and precompiled libraries. Note, that GNU ld I use is patched to support alternative linker, and ld-gnu-to-sun is a wrapper for solaris ld.
