RHBA-2011:0578 - elfutils bug fix update

Synopsis

elfutils bug fix update

Type/Severity

Bug Fix Advisory

Topic

Updated elfutils packages that resolve an issue are now available.

Description

The elfutils package contains utilities and libraries for working with compiled binary files. Its libraries are used by the SystemTap instrumentation system found in the systemtap package.

These updated elfutils packages fix the following bug:

• After prelink had been run on the system, using SystemTap user-space probes that targeted functions or statements in certain shared libraries, or executables based on a separate debuginfo file, caused resolution to the wrong PC location in a linked binary. As a result, the intended probes failed to fire at the correct place in the program, which could have caused the program to crash or misbehave due to a corrupted instruction sequence resulting from incorrect breakpoint insertions. With this update, the libdwfl library code (the libdw.so shared object library) was adjusted to use a more reliable method of compensating for prelink's effect on the address layout of a binary when aligning a runtime PC address with an address computed separately from the separated debuginfo file. SystemTap probes should now work the same on prelinked binaries as they would on binaries that have not been prelinked. (BZ#652858)

All users of SystemTap and elfutils are advised to upgrade to these updated packages, which resolve this issue.
