RHBA-2014:1415 - Bug Fix Advisory

Topic

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

Description

The strace utility intercepts and records the system calls that are made and
received by a running process and prints a record of each system call, its
arguments, and its return value to standard error output or a file. It is often
used for problem diagnoses, debugging, and for instructional purposes.

This update fixes the following bugs:

• Previously, the strace utility incorrectly assumed that the size of the

integer data type and the size of the long data type was the same. As a
consequence, strace incorrectly printed the options of a getsockopt call on
targets with different sizes of integer and long. A patch has been applied to
address this bug, and strace no longer returns incorrect values in the described
situation. (BZ#862321)

• Previously, invalid system calls were not required to have names in the system

calls table. As a consequence, running the "strace -c -S name" command resulted
in a segmentation fault under certain circumstances. With this update, invalid
system calls are properly handled, and sorting calls by name now works as
expected. (BZ#1044605)

Users of strace are advised to upgrade to these updated packages, which fix
these bugs.

Solution

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

This update is available via the Red Hat Network. Details on how to
