RHBA-2011:0769 - Bug Fix Advisory

Topic

Updated NetworkManager packages that fix a number of bugs and add some
enhancements are now available.

Description

NetworkManager is a system network service that manages network devices
and connections, attempting to keep active network connectivity when
available. It manages Ethernet, wireless, mobile broadband (WWAN), and
PPPoE devices, and provides VPN integration with a variety of different
VPN services.

This update fixes the following issues:

• After Wireless was disabled in NetworkManager, a suspend and resume

operation caused the wireless connection to become enabled automatically.
This is now fixed to preserve the user set wireless state even after an
rfkill operation (suspend and resume). (BZ#584271)

• Translations had assorted inconsistencies, including invalid characters

as part of the network-manager-applet (languages: as, te, pa, gu, mr,
fr, es, bn_IN) and NetworkManager (languages: bn_IN, es, fr, ja, mr).
These are now fixed to display the correct translated strings. (BZ#589230)

• Due to a type truncation problem on 64-bit PPC systems, correctly

configured connections was not displayed in connection editor. This is
now fixed and connections are properly shown in the editor on all
platforms as expected. (BZ#608663)

• Unprivileged users could change the status of the wireless connection

and WWAN. This is now fixed to display a "not authorized" error for any
unauthorized users attempting to change the wireless status. (BZ#626337)

• NetworkManager would insert warning messages in the /var/log/messages

log file due to the hostname operation. This is now fixed to ensure no
unnecessary warnings display during the hostname operation. (BZ#627649)

• Occasionally, the NetworkManager panel applet would not be able to

determine user permissions to enable networking and therefore disabled
the "Enable Networking" and "Enable Wireless" check boxes. This is now
fixed to ensure that if the user has permissions to enable networking,
the check boxes display as expected. (BZ#633501)

• Roaming between WPA/WPA2 access points in the same SSID attached to

the same wireless LAN controller resulted in an unexpected
re-authentication requirement. This is now fixed so that the SSID
is preserved to be used again after a legitimate roaming disconnection
event. (BZ#636877)

• Configurations that used multiple network devices where one device was

an iSCSI adapter that should not have the default route were incorrectly
handled. This is now fixed to ensure that iSCSI devices that are denied
the default route do not receive it. (BZ665027)

• IPv6 static addressing configurations were unable to correctly save the

gateway address. This is now fixed to ensure that the gateway address now
saves the first configured IPv6 address. (BZ#666078)

• NetworkManager used to update /etc/hosts file, which could cause

problems in some configurations. This is now fixed and NetworkManager
does not modify /etc/hosts, leaving it for the administrator to set up.
(BZ#668830)

• NetworkManager saved the WPA/WPA2 password despite selecting the "Ask

for this password every time" option and presented a password field with
some text when prompting the user to enter a new WPA/WPA2 connection
password. This is fixed so that NetworkManager does not store passwords
when "Ask for this password every time" is selected and displays an empty
password field when prompting the user for the password. (BZ#692578)

This update adds also the following enhancements:

• IPv6 information such as the IP Address and DNS servers now displays in

the connection information. (BZ#634152)

• DHCP lease change events now trigger dispatcher scripts at the

/etc/NetworkManager/dispatcher.d location. (BZ#662730)

Users are advised to upgrade to these updated packages, which resolve
these issues and add these enhancements.
