From: Jann Horn Date: Wed, 10 Apr 2019 16:54:34 +0000 (-0700) Subject: LSM: SafeSetID: fix pr_warn() to include newline X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=c783d525f9e7e1fd6a5dc3379f3c1fb041495b76;p=openwrt%2Fstaging%2Fblogic.git LSM: SafeSetID: fix pr_warn() to include newline Fix the pr_warn() calls in the SafeSetID LSM to have newlines at the end. Without this, denial messages will be buffered as incomplete lines in log_output(), and will then only show up once something else prints into dmesg.
