RHBA-2013:0345 - systemtap bug fix and enhancement update

Synopsis

systemtap bug fix and enhancement update

Type/Severity

Bug Fix Advisory (none)

Topic

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

Description

SystemTap is a tracing and probing tool to analyze and monitor activities of the operating system, including the kernel. It provides a wide range of filtering and analysis options.

The systemtap packages have been upgraded to upstream version 1.8, which provides a number of bug fixes and enhancements over the previous version. (BZ#843123)

This update also fixes the following bugs:

• Many of the SystemTap examples for memory used tracepoints which did not exist in some versions of kernel. Consequently, if the user tried to run the mmanonpage.stp, mmfilepage.stp, or mmwriteback.stp files, this process failed. The examples have been updated to work with the memory tracepoints available in Red Hat Enterprise Linux 6 and SystemTap now works as expected. (BZ#746334)

• Previously, support for the IPv6 protocol was missing. Consequently, an attempt to execute a script that evaluates a tapset variable containing an IPv6 address, or call a tapset function returning an IPv6 address was unsuccessful, and the address field was filled with the "Unsupported Address Family" message instead of a valid IPv6 address. This update adds the support for the IPv6 protocol. (BZ#822503)

• Previously, changes in the include/trace/events/sunrpc.h file were referenced, but were not defined by the #include directive. As a consequence, the rpc tracepoint was missing. This tracepoint has been defined using #include and SystemTap works correctly in this situation. (BZ#824311)

• In previous kernels and versions of SystemTap, the nfsd.open probe-alias in the nfsd tapset referred to the "access" parameter, which was later renamed to "may_flags" in the kernel. Consequently, the semantic errors occurred and then the stap command failed to execute. This update allows the nfsd.open probe-alias check under both names for setting the "access" script-level variable, and stap now works as expected in the described scenario. (BZ#828103)

• Recent kernel updates required updates to some of the NFS tapset definitions to find certain context variables. With this update, the tapset aliases now search both old and new locations. (BZ#884951)

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