-qemu user calls malloc after fork in multi-threaded process
-
-qemu user may hang in malloc on a musl based system because
-it calls malloc after fork (in a pthread_atfork handler)
-in the child process.
-
-this is undefined behaviour since the parent process is
-multi-threaded and only as-safe functions may be called
-in the child then. (if malloc/free is called concurrently
-with fork the malloc state will be corrupted in the child,
-it works on glibc because glibc takes the malloc locks
-before the fork syscall, but that breaks the as-safety of
-fork and thus non-conforming to posix)
-
-discussed at
-https://www.openwall.com/lists/musl/2019/01/26/1
-
-the bug is hard to reproduce (requires the call_rcu thread
-to call free concurrently with do_fork in the main thread),
-this one is observed with qemu-arm 3.1.0 running on x86_64
-executing an arm busybox sh:
