Subject: Add return check for 'lxc_cmd_get_name'
X-Git-Tag: lxc-2.0.10~425
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3380e58a1fe060dfba7a7d09c1b492ff46931d3c;p=thirdparty%2Flxc.git

Add return check for 'lxc_cmd_get_name'

If 'lxc_cmd_get_name' failed and return with NULL, this would cause a segment fault.
