Red Hat Product Errata RHBA-2015:1308 - Bug Fix Advisory

RHBA-2015:1308 - Bug Fix Advisory

  • Overview
  • Updated Packages

Synopsis

strace bug fix and enhancement update

Type/Severity

Bug Fix Advisory

Topic

Updated strace packages that fix several bugs and add various enhancements 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.

The strace packages have been upgraded to upstream version 4.8, which provides a
number of bug fixes and enhancements over the previous version. Among others:

  • This update adds several new command-line options: "-y" to print file
    descriptor paths, "-P" to filter system calls based on the file descriptor
    paths, and "-I" to control how interactive strace is.
  • A new command-line utility, strace-log-merge, has been added. This utility can
    be used to merge timestamped strace output into a single file.
  • The strace utility now uses optimized interfaces to extract data from the
    traced process for better performance.
  • The strace utility now provides improved support for decoding of arguments for
    various system calls. In addition, a number of new system calls are supported.

(BZ#919101, BZ#1056828)

This update also fixes the following bug:

  • Previously, the strace utility incorrectly handled the return value from the
    shmat() system call. Consequently, the return value displayed was "?" instead of
    the address of the attached shared memory segment. This bug has been fixed, and
    strace now displays the correct return value for the shmat() system calls.
    (BZ#877193)

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

Solution

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