From mboxrd@z Thu Jan 1 00:00:00 1970 From: Yang Xu Date: Wed, 12 Feb 2020 13:44:46 +0800 Subject: [LTP] [PATCH] syscalls/kill11: add a check between hard limit and MIN_RLIMIT_CORE Message-ID: <1581486286-13615-1-git-send-email-xuyang2018.jy@cn.fujitsu.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: ltp@lists.linux.it Currently, running this case will report EINVAL error if I run "ulimit -c 1023" command firstly. From setrlimit(2)manpage, it got EINVAL error because rlim->rlim_cur was greater than rlim->rlim_max. So add a check for it before setrlimit.
