CVS commit: src

Module Name:    src
Committed By:   joerg
Date:           Thu Apr 16 14:39:58 UTC 2020

Modified Files:
        src/lib/libc/gen: pthread_atfork.c
        src/libexec/ld.elf_so: rtld.c rtld.h

Log Message:
Introduce intermediate locking for fork, so that the dynamic linker is
in a consistent state. This most importantly avoids races between dlopen
and friends and fork, potentially resulting in dead locks in the child
when it itself tries to acquire locks.
