RHBA-2017:0849 - Bug Fix Advisory

Topic

Updated kernel packages that fix two bugs are now available for Red Hat Enterprise Linux 6.5 Advanced Update Support.

Description

The kernel packages contain the Linux kernel, the core of any Linux
operating system.

This update fixes the following bugs:

• Previously, the mpt3sas driver incorrectly checked the Transport Layer Retries (TLR) state even on Redundant Array Of Independent Discs (RAID) devices. Consequently, a kernel panic occurred when mpt3sas attempted to read from the RAID devices. With this update, mpt3sas has been fixed to check the TLR state only for non-RAID devices, and the kernel no longer panics under the described circumstances. (BZ#1427455)
• Previously, kernel did not correctly handle /dev/console users when the terminal became unresponsive. Consequently, a kernel crash in some cases occurred when using the pseudoterminal master-slave devices. This update adds a check to make sure that no other users are waiting for data before a hangup is issued. As a result, the kernel no longer crashes under the described circumstances. (BZ#1428314)

All users are advised to upgrade to these updated packages, which fix these bugs. The system must be rebooted for this update to take effect.
