From c01ff965b48bb9693dcd77cbc748b5d8676766b0 Mon Sep 17 00:00:00 2001 From: Lennart Poettering Date: Thu, 9 Jul 2015 14:46:20 -0300 Subject: nss-mymachines: map userns users of containers to real user names Given a container "foo", that maps user id $UID to container user, using user namespaces, this NSS module extenstion will now map the $UID to a name "vu-foo-$TUID" for the translated UID $UID. Similar, userns groups are mapped to "vg-foo-$TGID" for translated GIDs of $GID. This simple change should make userns users more discoverable. Also, given that many tools like "adduser" check NSS before allocating a UID, should lower the chance of UID range conflicts between tools. --- src/libsystemd/sd-bus/bus-common-errors.h | 2 ++ 1 file changed, 2 insertions(+) (limited to 'src/libsystemd') diff --git a/src/libsystemd/sd-bus/bus-common-errors.h b/src/libsystemd/sd-bus/bus-common-errors.h index 0dbfbddcf6..f2092795f4 100644 --- a/src/libsystemd/sd-bus/bus-common-errors.h +++ b/src/libsystemd/sd-bus/bus-common-errors.h @@ -46,6 +46,8 @@ #define BUS_ERROR_NO_MACHINE_FOR_PID "org.freedesktop.machine1.NoMachineForPID" #define BUS_ERROR_MACHINE_EXISTS "org.freedesktop.machine1.MachineExists" #define BUS_ERROR_NO_PRIVATE_NETWORKING "org.freedesktop.machine1.NoPrivateNetworking" +#define BUS_ERROR_NO_SUCH_USER_MAPPING "org.freedesktop.machine1.NoSuchUserMapping" +#define BUS_ERROR_NO_SUCH_GROUP_MAPPING "org.freedesktop.machine1.NoSuchGroupMapping" #define BUS_ERROR_NO_SUCH_SESSION "org.freedesktop.login1.NoSuchSession" #define BUS_ERROR_NO_SESSION_FOR_PID "org.freedesktop.login1.NoSessionForPID" -- cgit v1.2.3-54-g00ecf
