RHBA-2012:0906 - Bug Fix Advisory

Topic

Updated udev packages that fix multiple bugs are now available for Red Hat
Enterprise Linux 6.

Description

The udev packages implement a dynamic device-directory, providing only the
devices present on the system. This dynamic directory runs in user space,
dynamically creates and removes devices, provides consistent naming, and a
user-space API. The udev package replaces the devfs package and provides better
hot plug functionality.

This update fixes the following bugs:

• Previously, libudev's function udev_device_get_devnode() returned NULL if the

function was called before the udevd daemon processed the uevent for the device
node. With this update, the udev_device_get_devnode() function now returns the
devnode provided by the kernel. (BZ#784648)

• Previously, the udev-post non-service script located in the /etc/init.d/

directory always returned a failure code on a status request. This bug has been
fixed in this update so that the udev-post service now returns information on
whether it has already been run. (BZ#735410)

• Previously, the udev(7) man page did not mention the "nowatch" option. With

this update, the "nowatch" option is now properly documented in the udev(7) man
page. (BZ#628762)

All users of udev are advised to upgrade to these updated packages, which fix
these bugs.
