With commit f0b2132b35248c1f4a80f62a2c38cddcc802aa8c ("ld.so: Support moving versioned symbols between sonames [BZ #24741]"), the dynamic linker will find the definition of vfork in libc and binds a vfork reference to that symbol, even if the soname in the version reference says that the symbol should be located in libpthread. As a result, the forwarder (whether it's IFUNC-based or a duplicate of the libc implementation) is no longer necessary. On older architectures, a placeholder symbol is required, to make sure that the GLIBC_2.1.2 symbol version does not go away, or is turned in to a weak symbol definition by the link editor. mips32 is an outlier: It defined __vfork@@GLIBC_2.2, but the baseline is GLIBC_2.0. Since there are other @@GLIBC_2.2 symbols, the placeholder symbol is not needed there. (I tested this on i386 and with a build-many-glibcs.py run. I tried to verify manually that libc.so provides the same symbol versions as the removed ones. We already removed all the other IFUNC forwarders which were originally there, and vfork was the only remaining case where we had a user-visible bug. Therefore, removing the remaining forwarders is just a further cleanup, not a functional change.) 2019-06-28 Florian Weimer <fweimer@redhat.com> [BZ #20188] * nptl/Versions (libpthread): Remove __fork from GLIBC_2.0.
