RHEA-2011:1747 - Product Enhancement Advisory

Topic

An updated kabi-whitelists package that adds various enhancements is now
available for Red Hat Enterprise Linux 6.

Description

The kabi-whitelists package contains reference files documenting interfaces
provided by the Red Hat Enterprise Linux 6 kernel that are considered to be
stable by Red Hat kernel engineering, and safe for longer term use by third
party loadable device drivers, as well as for other purposes.

This update adds the following enhancements:

• The "pci_reset_function" symbol has been added to the Red Hat Enterprise Linux

6.2 kernel application binary interface (ABI) whitelists. (BZ#680469)

• The "aio_complete" and "aio_put_req" symbols have been added to the kernel ABI

whitelists. (BZ#690479)

• The "__blk_end_request", "bdget_disk", "blk_limits_io_min",

"blk_limits_io_opt", "blk_plug_device", "blk_queue_bounce",
"blk_queue_max_discard_sectors", "blk_remove_plug", "blk_requeue_request",
"jiffies_to_usecs", "prepare_to_wait_exclusive", "ipv6_ext_hdr",
"lro_receive_frags", and "lro_vlan_hwaccel_receive_frags" symbols have been
added to the kernel ABI whitelists. (BZ#700406)

• The "ipv6_ext_hdr", "lro_receive_frags", and "lro_vlan_hwaccel_receive_frags"

symbols have been added to the kernel ABI whitelists. (BZ#700432)

• The "ipv6_ext_hdr", "lro_receive_frags", "lro_vlan_hwaccel_receive_frags",

"netif_set_real_num_tx_queues", and "pci_find_ext_capability" symbols have been
added to the kernel ABI whitelists. The only exception is
"pci_find_ext_capability", which is not available for IBM System z. (BZ#702675)

• The "compat_alloc_user_space" symbol has been added to the kernel ABI

whitelists. (BZ#703125)

• The "paca" symbol has been added to the kernel ABI whitelists for the 64-bit

PowerPC architecture. (BZ#730410)

• The "dm_put_device", "enl_register_ops", "m_device_name",

"m_unregister_target", "m_register_target", "m_table_get_mode",
"m_table_get_md", "m_get_device", and "enl_register_family" symbols have been
added to the kernel ABI whitelists. (BZ#748520)

Note: It is not necessary to install the kabi-whitelists package in order to use
Driver Updates. The kabi-whitelists package only provides reference files for
use by those creating Driver Update packages, or for those who wish to enable
support for verification of kernel ABI compatibility by installing the
appropriate Yum plug-in.

All users of kabi-whitelists are advised to upgrade to this updated package,
which adds these enhancements.
