Chapter 1. Package Updates
This update fixes the following issue:
* the FIPS-140-2 standard requires cryptographic modules to provide methods to "zeroize" (meaning:
to overwrite with zeroes) all plain text secret and private cryptographic keys and Critical Security
Parameters (CSPs). With this update, Openswan uses methods supplied by the NSS library to
perform zeroization on plain text secret and private cryptographic keys and CSPs.
All users of openswan are advised to upgrade to these updated packages, which resolve this issue.
1.147. oprofile
1.147.1. RHBA-2010:0283: bug fix and enhancement update
An updated oprofile package that corrects architecture-specific bugs and adds support for Nehalem-
EP and IBM POWER7 processors is now available.
OProfile is a system-wide profiler for Linux systems. The profiling runs transparently in the background
and profile data can be collected at any time. OProfile uses the hardware performance counters
provided on many processors, and can use the Real Time Clock (RTC) for profiling on processors
without counters.
This update applies the following fixes and enhancements:
* An incorrect argument in a binutil library call caused a segmentation fault in opreport whenever the --
debug-info option was used. The elf_find_function() function in libbfd required a non-NULL symbol, but
opreport did not receive a warning whenever NULL symbols were present. This update adds an early
warning system for this, thereby resulting in more graceful error reporting for the presence of NULL
symbols rather than a segmentation fault.
* OProfile now supports Nehalem-EP processor performance events.
* When the OProfile daemon started on the Itanium architecture, it created children processes to run
perfmon; however, those children processes did not properly close file descriptors for stdin, stdout,
and stderr. This could prevent oprofiled from properly sending output to any third-party applications.
This update corrects the behavior by adding close() functions for open stdin, stdout, and stderr file
descriptors, which corrects the daemon behavior on the Itanium architecture.
* A regression in the binutils-devel static library caused the bfd_get_section_by_name() function
to produce incorrect output. This regression was caused by an error that was present in the
binutils-devel specfile when it was compiled. Since OProfile uses binutils-devel at compile time,
bfd_get_section_by_name() also cause opreport -l to fail. With this release, binutils-devel is compiled
with a corrected specfile; OProfile is then re-compiled with this version of binutils-devel, thereby fixing
the regression.
(BZ#527679
* OProfile now supports the IBM POWER7 processor.
All OProfile users should apply this update.
