Subject: MINOR: mworker: set the master side of ipc_fd in the worker to -1
X-Git-Tag: v2.6-dev1~24
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7e01878e4591b36218dad1326662704476982523;p=thirdparty%2Fhaproxy.git

MINOR: mworker: set the master side of ipc_fd in the worker to -1

Once the child->ipc_fd[0] is closed in the worker, set the value to -1
so we don't reference a closed FD anymore.
