[Bug 1715641] Re: network-manager built against glibc-2.26 requires GLIBC_2.25 symbol yet doesn't depend on recent enough glibc

[Matthias Klose]

I think there is at least a bug in network-manager: it defines (for
whatever reason) an explicit_bzero function, which is not used when
building with -D_FORTIFY_SOURCE.  The reference in string_erase is
transformed from explicit_bzero to explicit_bzero_chk. So if network-
manager defines explicit_bzero, then it should define explicit_bzero_chk
as well.

Note that linking with gold (both 2.28 and 2.29) you end up with an
undefined symbol GLIBC_2.25  __explicit_bzero_chk.

The bfd linker however seems to optimize that out, and doesn't leave any
undefined symbol. However in ld-2.29 it leaves a reference in

Version needs section '.gnu.version_r' contains 9 entries:

  0x0170:   Name: GLIBC_2.25  Flags: none  Version: 11

Removing this unused explicit_bzero function seems to work, and the
string-util.h is not installed anywhere, it shouldn't be part of any
API.

I believe this is a bug in dpkg, since it does not parse 'Version
References:' paragraph of data.

maybe Dpkg/Shlibs/Objdump.pm doesn't parse that section?

Or maybe objdump output changed, hence the parsing fails?
