Bug 1709720

This issue applies to DTS binutils build as well, cloning the RHEL8 bug to include Nick's comments, especially the upstream report & the patch.


With devtoolset-8-binutils-2.30-54:

CFLAGS='-m32 -fstack-protector-all -fsanitize=address' CXXFLAGS='-m32 -fstack-protector-all -fsanitize=address' ./configure --disable-shared --disable-gdb --disable-libdecnumber --disable-readline --disable-sim && make all-binutils

ends with:

I'm using this build to verify some (not major) CVEs. My two cents - not that important to cause a respin, but nice to get a fix in the next DTS round. Feel free to postpone.

Description of problem:
binutils fails to compile with CFLAGS='-fsanitize=address -ggdb' CXXFLAGS='-fsanitize=address -ggdb' LDFLAGS='-fsanitize=address'

Version-Release number of selected component (if applicable):
binutils-2.30-49.el8.x86_64

How reproducible:
for binutils-2.30-49.el8.src.rpm

Steps to Reproduce:
1. CFLAGS='-fsanitize=address -ggdb' CXXFLAGS='-fsanitize=address -ggdb' LDFLAGS='-fsanitize=address' ./configure
2. LSAN_OPTIONS=detect_leaks=0 make all-binutils

Actual results:
/usr/bin/ld: /root/rpmbuild/BUILD/binutils-2.30/bfd/.libs/libbfd.a(plugin.o): undefined reference to symbol 'dlsym@@GLIBC_2.2.5'
//usr/lib64/libdl.so.2: error adding symbols: DSO missing from command line

Hi Alexandra,

  This is basically a duplicate of https://sourceware.org/bugzilla/show_bug.cgi?id=22318.

  I am pushing fixing this problem out to 8.1.0 since the binutils are not normally built
  with sanitization enabled.

Cheers
  Nick

This is the patch used in the GNU Binutils sources to fix this problem.

Note - in order for this patch to be effective it is necessary to configure the binutils with --enable-plugins option.
