From a03d6d2fab13c478a0f6cfc3082bec141f2adcf1 Mon Sep 17 00:00:00 2001 From: Jo-Philipp Wich Date: Thu, 28 May 2020 13:03:02 +0200 Subject: [PATCH] broadcom-wl: don't inherit lock descriptor in nas process Add a local hack to prevent the Broadcom WPA authenticator process from inheriting the lock descriptor 1000 used to prevent concurrent executions of the init script. Without this fix, repeated invocations of /etc/init.d/network, e.g. for obtaining the enabled state, would hang forever.
