RHBA-2018:1794 - Bug Fix Advisory
Synopsis
kernel bug fix update
Type/Severity
Bug Fix Advisory
Topic
Updated kernel packages that fix several bugs are now available for Red Hat Enterprise Linux 7.2 Advanced Update Support.
[Updated 11 Jun 2018]
This advisory has been updated with the description of BZ#1578043. The packages included in this revised update have not been changed in any way from the packages included in the original advisory.
Description
The kernel packages contain the Linux kernel, the core of any Linux operating system.
This update fixes the following bugs:
- When the system was under a heavy load, the TX driver in some cases became unresponsive and TCP performed poorly. As a consequence, TX became unresponsive and TCP performed poorly. This update prevents the race condition in the TX driver code and sets the VMXNET 3 internal LRO flag properly. As a result, TX does not become unresponsive and TCP performs as expected under the heavy load. (BZ#1567752)
- Previously, the UEFI top-level page table was not configured properly to work with the page table isolation (PTI) feature. As a consequence, certain memory locations got corrupted and page tables were set incorrectly, which caused random crashes or system reboots without any error message. With this update, the UEFI top-level page table has been modified to reflect the PTI requirement. As a result, the described problems no longer occur. (BZ#1567890)
- When a CPU thread went into an idle state, the Indirect Branch Restricted Speculation (IBRS) feature remained enabled on the core. As a consequence, the performance of the idle CPU's sibling decreased. This update disables IBRS before the CPU enters the idle state. As a result, the idle CPU thread no longer decreases the performance of its sibling. (BZ#1570529)
- Previously, an erroneous code in the x86 kexec system call path caused a memory corruption. As a consequence, the system became unresponsive with the following kernel stack trace:
'WARNING: CPU: 13 PID: 36409 at lib/list_debug.c:59 __list_del_entry+0xa1/0xd0 list_del corruption. prev->next should be ffffdd03fddeeca0, but was (null)'
This update ensures that the code does not corrupt memory. As a result, the operating system no longer hangs. (BZ#1573167)
- Previously, microcode updates on 32 and 64-bit AMD and Intel architectures were not synchronized. As a consequence, it was not possible to apply the microcode updates. This fix adds the synchronization to the microcode updates so that processors of the stated architectures receive updates at the same time. As a result, microcode updates are now synchronized. (BZ#1578043)
Users of kernel are advised to upgrade to these updated packages, which fix these bugs. The system must be rebooted for this update to take effect.
Solution
