File 0005-util-avoid-double-close-of-fd.patch of Package systemd
Based on 6f53e671aa7539cab02c9f739d84d28a343ca5bc Mon Sep 17 00:00:00 2001 From: Thomas Hindoe Paaboel Andersen <phomes@gmail.com> Date: Wed, 8 Oct 2014 23:57:32 +0200 Subject: [PATCH] util: avoid double close of fd We could end with a double close if we close the fd loop and flush_fd fails. That would make us goto fail and there we close the fd once again. This patch sets the fd to the return value for safe_close: -1 A fd with negative value will be ignored by the next call to safe_close.
