RHBA-2011:0232 - Bug Fix Advisory

Topic

An updated udev package that fixes three bugs is now available for Red Hat
Enterprise Linux 4.

Description

The udev package implements 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. udev replaces devfs in order to provide greater hot plug
functionality.

This update fixes the following bugs:

• Previously, the dasd_id callout created temporary device nodes to check the

device IDs, which were not cleaned up correctly. Due to this behavior, /tmp
contained a large amount of temporary device nodes. This update improves the
cleanup procedure of dasd_id. No more temporary device nodes are left in /tmp.
(BZ#457387)

• Previously, the scsi_id callout could not query cciss devices for information.

Due to this behavior, scsi_id returned no id string for cciss devices. This
update extends the scsi ID to handle cciss devices, and scsi_id now returns id
strings for cciss devices. (BZ#493937)

• Previously, the udev package did not contain explicit permission entries for

ttyACM devices. Due to this behavior, ttyACM devices were assigned the default
permissions, preventing the uucp group from having read/write access. This
update adds an explicit permission entry to the udev permission file to assign
ttyACM devices to the uucp group. The uucp group now has read/write access to
ttyACM devices. (BZ#496967)

All udev users are advised to upgrade to this updated package, which fixes these
bugs.
