Subject: Don't change rl.rlim_max for RLIMIT_CORE.  We need only set rl.rlim_cur
X-Git-Tag: SUDO_1_6_8~337
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=e15de8443d5cea3f968a270e1018112d74748a20;p=sudo

Don't change rl.rlim_max for RLIMIT_CORE.  We need only set rl.rlim_cur
to 0 to turn off core dumps.  This may be needed for the RLIMIT_CORE
restoration on some OSes.
