RHBA-2011:1150 - systemtap bug fix update

Synopsis

systemtap bug fix update

Type/Severity

Bug Fix Advisory (none)

Topic

Updated systemtap packages that fix two bugs bug are now available for Red Hat Enterprise Linux 6.

Description

SystemTap is an instrumentation system for systems running the Linux kernel, version 2.6. Developers can write scripts to collect data on the operation of the system.

This update fixes the following bugs:

• When the system ran out of memory in a module, systemtap failed to remove the module directory created by the debugfs debugger. Consequently, systemtap was unable to load the same module until after a system reboot; sometimes even a kernel panic occurred. With this update, a patch has been provided to address this issue, and systemtap now properly removes the module directory in the described scenario, thus fixing this bug. (BZ#725809)

• Under unusual circumstances, the rate of error or warning messages sent from the probe module to userspace exceeded various buffers. As a consequence, some control messages were sometimes lost which eventually led to a kernel panic in some cases. With this update, the transport layer ensures that all control messages are delivered even if there is a flood of warning or error messages, thus fixing this bug. (BZ#726051)

Affected systemtap users should upgrade to these updated packages, which fix these bugs.
