RHBA-2015:1333 - systemtap bug fix and enhancement update

Synopsis

systemtap bug fix and enhancement update

Type/Severity

Bug Fix Advisory

Topic

Updated systemtap packages that fix several bugs and add various enhancements are now available for Red Hat Enterprise Linux 6.

Description

SystemTap is an instrumentation system for systems running the Linux kernel, which allows developers to write scripts to collect data on the operation of the system.

The systemtap packages have been upgraded to upstream version 2.7, which provides a number of bug fixes and enhancements over the previous version. (BZ#1158682)

This update also fixes the following bugs:

  • Previously, some startup-time scripts required the "uprobes.ko" module built, installed, or loaded, but the init script did not identify whether and how to do so. A patch has been applied to fix this bug, and the init script now performs the appropriate operations. (BZ#1118352)

  • Prior to this update, the systemtap scripts caused the "scheduling while atomic" error when running on the Messaging Real-time Grid kernel. To fix this bug, patches have been applied, and the error no longer occurs. (BZ#1147647)

  • The systemtap's "tapset" system call unconditionally included support for the "execveat" system call, even though "execveat" did not exist in Red Hat Enterprise Linux 6 kernels. Consequently, system call probing scripts could fail with a semantic error. With this update, "execveat" is treated conditionally, and the scripts no longer fail in this situation. (BZ#1195839)

Users of systemtap are advised to upgrade to these updated packages, which fix these bugs and add these enhancements.

Solution

Before applying this update, make sure all previously released errata relevant to your system have been applied.
