Hi Pablo, Pablo Neira Ayuso <pablo@xxxxxxxxxxxxx> writes: > Probably remove the check for lock_file[0] == '\0' > > Or is this intentional? I've added it intentionally as I think it is safer to ignore an empty string. The programs I've checked, GNU coreutils and GNU grep, have the same check. The empty string will likely fail on open(2), at least on tmpfs it does with ENOENT. If you want though, I can drop the check. > git grep getenv in iptables does not show any similar handling for > getenv(). not sure if that is the desired behaviour as it will be processed as an empty string.
