RHBA-2014:1415 - strace bug fix update

Synopsis

strace bug fix update

Type/Severity

Bug Fix Advisory (none)

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 use the Red Hat Network to apply this update are available at https://access.redhat.com/articles/11258
