+
+One of our partners has noticed that cgred daemon is creating a log file
+(/var/log/cgred) with too wide permissions (0666) and that is seen as
+a security bug because an untrusted user can write to otherwise
+restricted area. CVE-2018-14348 has been assigned to this issue.

+Subject: [PATCH] api.c: fix order of memory subsystem parameters generated by
+ cgsnapshot
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Order of parameters usually doesn't matter, but that's not the case with
+memory.limit_in_bytes and memory.memsw.limit_in_bytes. When the latter
+is first in the list of parameters, the resulting configuration is not
+loadable with cgconfigparser.
+
+This happens because when a cgroup is created, both memory.limit_in_bytes
+and memory.memsw.limit_in_bytes parameters are initialized to highest
+value possible (RESOURCE_MAX). And because memory.memsw.limit_in_bytes
+must be always higher or equal to memory.limit_in_bytes, it's impossible
+to change its value first.
+
+Make sure that after constructing parameter list of memory subsystem,
+the mentioned parameters are in correct order.

+MIME-Version: 1.0

+
+When setting cgroup parameters with cgset fails, no error is reported.
+This is caused by the fact that cgroup_copy_controller_values is not

+Subject: [PATCH] api.c: support for setting multiline values in control files
+
+As of now, libcgroup does not support multiline values setting from configuration files. i.e. values in a form:
+
+net_prio.ifpriomap="lo 7
+eth0 66
+eth1 5
+eth2 4
+eth3 3";
+
+Thus, setting of more network interfaces can not be done from configuration file. Or
+
+devices.allow="a *:* w
+c 8:* r";
+
+thus setting list of allow devices can not be set as well. The only way is to set it from userspace, e.g.:
+# echo "lo 7" > /sys/fs/cgroup/net_prio/testGroup/net_prio.ifpriomap
+# echo "eth 0" > /sys/fs/cgroup/net_prio/testGroup/net_prio.ifpriomap
+# echo "eth 1" > /sys/fs/cgroup/net_prio/testGroup/net_prio.ifpriomap
+# echo "eth 2" > /sys/fs/cgroup/net_prio/testGroup/net_prio.ifpriomap
+# echo "eth 3" > /sys/fs/cgroup/net_prio/testGroup/net_prio.ifpriomap
+
+This patch allows setting of multiline variables.
+
+How this support works:
+Multiline value is broken in lines and each line is set by write (man 2 write) syscall (without bufferring).
+This implies change of fopen with open, fclose with close.
+There is no control on multiline value, thus "eth0\n  \t\n" can be set. However, setting
+of "  \t" will fail as write command returns -1. Thus administrator has to set correct
+multiline values.
+
+Tested on virtual machine with fedora and rhel with network interface lo, eth0-eth3. Configuration file:
+
+# cat /etc/cgconfig.conf
+group testGroup {
+        net_prio {
+                net_prio.ifpriomap="lo 7
+eth0    66
+eth1 5
+eth2 4
+eth3 3";
+        }
+}
+
+net_prio has to be created before:
+# modprobe netprio_cgroup
+# mkdir /sys/fs/cgroup/net_prio
+# mount -t cgroup -onet_prio none /sys/fs/cgroup/net_prio
+
+Changelog:
+	test of success of strdup call
+	free str_val before return (str_val is changing in while cycle,
+		thus str_start_val points to the start of str_val before while)
