RHBA-2014:1413 - Bug Fix Advisory

Topic

Updated NetworkManager packages that fix two bugs are now available for Red Hat
Enterprise Linux 6.

Description

NetworkManager is a system network service that manages network devices and
connections, attempting to keep active network connectivity when available. Its
capabilities include managing Ethernet, wireless, mobile broadband (WWAN), and
PPPoE devices, as well as providing VPN integration with a variety of different
VPN services.

This update fixes the following bugs:

• When the machine suspended, the NetworkManager daemon deactivated all network

devices on that machine. Consequently, the Wake-on-LAN clients did not work
because this network device was powered down, and thus could not receive the
Magic Packet. With this update, NetworkManager leaves devices running at suspend
time if they have the Wake-on-LAN or Wake-on-Wireless-LAN variable enabled, and
Wake-on-LAN works as intended if the administrator enables it. (BZ#1025009)

• Previously, NetworkManager used the kernel's Point-to-point protocol over

Ethernet (PPPoE) driver, which did not inform userland when it received a PPPoE
Active Discovery Terminate (PADT) frame. As a consequence, when connecting to
certain digital subscriber line (DSL) providers, the NetworkManager daemon
failed to notice whether the connection was dropped. With this update,
NetworkManager uses a userland PPPoE driver rather than the kernel driver, and
dropped DSL connections are now noticed for all providers. (BZ#1034860)

• NetworkManager automatically provides an autoconnect for interfaces.

Previously, when this connection was altered and saved, NetworkManager
terminated unexpectedly. The write_ip4_setting() function has been updated to
fix this bug, and NetworkManager no longer crashes after saving altered
configuration. (BZ#1113996)

Users of NetworkManager are advised to upgrade to these updated packages, which
fix these bugs.
