Found the problem with this.
When you send the mode option :
my %options = ('create' => 'yes' ,
'exclusive' => 'no' ,
'mode' => '0666',
'destroy' => 'no' ,
) ;
to the back end, freebsd interprets '0666' ( world readable and
writeable ) as world _writeable_, thus making it only accessible by
root. Removing the 'mode' argument and letting it default takes care
of the problem.
Am I misreading the perm masks here or is this a bug that needs to go
to send-pr? In 3.0 the mode command worked fine.
ipcs results :
With 'mode' specified as '0666' :
m 131075 1313361738 ---w--wa-w- www www
With no mode specified :
m 65541 5432 --rw-rw-rw- www www
