[Bug gold/28876] New: gold should error out when creating a direct reference to protected function
https://sourceware.org/bugzilla/show_bug.cgi?id=28876
Bug ID: 28876
Summary: gold should error out when creating a direct reference
to protected function
Product: binutils
Version: 2.38
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: gold
Assignee: ccoutant at gmail dot com
Reporter: thiago at kde dot org
CC: ian at airs dot com
Target Milestone: ---
Related to #28875
Given library:
$ cat libb2.cpp
__attribute__((visibility("protected"))) long internal_i = 0;
__attribute__((visibility("protected"))) long internal_f()
{
return 2;
}
$ gcc -shared -fPIC -o libb.so libb2.cpp
$ eu-readelf --dyn-syms libb.so| grep internal
5: 4028 8 OBJECT GLOBAL PROTECTED 22 internal_i
6: 10f9 11 FUNCGLOBAL PROTECTED 11 _Z10internal_fv
gold already produces an error if it would need to create a copy relocation for
the variable:
$ cat main.cpp
extern __attribute__((visibility("default"))) long internal_i;
extern __attribute__((visibility("default"))) long internal_f();
int main()
{
internal_i = (long) _f;
}
$ gcc -fuse-ld=gold main.cpp libb.so
/usr/bin/ld.gold: error: /tmp/ccg0cNpy.o: cannot make copy relocation for
protected symbol 'internal_i', defined in libb.so
collect2: error: ld returned 1 exit status
However, it does not for the function address:
$ cat main.cpp
extern __attribute__((visibility("default"))) long internal_f();
int main()
{
return (long) _f;
}
$ gcc -fuse-ld=gold main.cpp libb.so
$ objdump --no-show -Cdr a.out| sed -n '/:/,/^$/p'
004005e6 :
4005e6: push %rbp
4005e7: mov%rsp,%rbp
4005ea: mov$0x4004f0,%eax
4005ef: pop%rbp

[Bug ld/28875] New: ld should warn or error out about creating copy relocs & direct external references for protected symbols
https://sourceware.org/bugzilla/show_bug.cgi?id=28875
Bug ID: 28875
Summary: ld should warn or error out about creating copy relocs
& direct external references for protected symbols
Product: binutils
Version: 2.38
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: ld
Assignee: unassigned at sourceware dot org
Reporter: thiago at kde dot org
Target Milestone: ---
Related: #15228, #17711, #27973.
For a library that has protected symbols:
$ cat libb2.cpp
__attribute__((visibility("protected"))) long internal_i = 0;
__attribute__((visibility("protected"))) long internal_f()
{
return 2;
}
$ gcc -shared -fPIC -o libb.so libb2.cpp
$ eu-readelf --dyn-syms libb.so| grep internal
5: 4028 8 OBJECT GLOBAL PROTECTED 22 internal_i
6: 10f9 11 FUNCGLOBAL PROTECTED 11 _Z10internal_fv
The linker should produce a warning when creating copy relocations or
position-dependent moves:
$ cat main.cpp
extern __attribute__((visibility("default"))) long internal_i;
extern __attribute__((visibility("default"))) long internal_f();
int main()
{
internal_i = (long) _f;
}
$ gcc main.cpp libb.so
[no error]
gold already does:
$ gcc -fuse-ld=gold main.cpp libb.so
/usr/bin/ld.gold: error: /tmp/ccg0cNpy.o: cannot make copy relocation for
protected symbol 'internal_i', defined in libb.so
collect2: error: ld returned 1 exit status
