8.2. NetworkManager

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

Bug Fixes

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