Description ritz 2008-04-09 14:21:30 UTC 
Description of problem:
acpid leaks file descriptors

Version-Release number of selected component (if applicable):
acpid-1.0.4-5

How reproducible:
always

Steps to Reproduce:
1. cat test.sh
for i in `seq  5`;do
	acpi_listen &
done

killall -qqq acpi_listen 2>&1  >/dev/null
sleep 1
/usr/sbin/lsof|grep acpi|grep socket|wc -l


2. sh test.sh
3. sh test.sh
  
Actual results:
acpid leaks fds

Expected results:
acpid should not leak fd

Additional info:
patch attached.

acpid uses unix sockets for ipc. It seems these sockets are not checked until
unless there is an acpi event generated.

any client which exits before an acpi event has been generated will leave around
an open fd, which will not be closed until when we try to write to it.
