[PATCH 0/2] Fix a few deadlocks with musl libc

Posted by Natanael Copa 3 years, 8 months ago

Fix a couple of deadlocks due to use of async-unsafe calls (malloc/free)
after fork() and before exec(). They don't fix all theoretical problems
but at least they make libvirt usable again with musl 1.2 on Alpine Linux.

Natanael Copa (2):
  util: avoid free() when reset log after fork
  util: command: improve generic mass close of fds
