RHBA-2011:0679 - Bug Fix Advisory

Topic

An updated man-pages package that corrects several documentation errors and
omissions and adds several improved man pages is now available for Red Hat
Enterprise Linux 6.

Description

The man-pages package provides man (manual) pages from the Linux
Documentation Project (LDP).

This updated man-pages package addresses the following issues:

• The sd man page had an invalid link referring to the scsi man page. With

this update, all references to the scsi man page were removed from the sd
man page. (BZ#634626)

• The "getent --help" command output mentioned a "-s" switch which was not

explained anywhere in the getent man page. Since the getent man page is
outdated, the entire page was removed for this update. (BZ#669768)

• The man page for clock_gettime had references to the CLOCK_REALTIME_HR

and CLOCK_MONOTONIC_HR constants, that were used in clock_getres.2,
clock_gettime.2, clock_nanosleep.2, clock_settime.2, and timer_create.2.
These constants are no longer present in the Linux kernel and clock_gettime
was corrected to remove all references to these constants. (BZ#678376)

• A typographical error in the SHA, MD5, and DES algorithms on crypt(3) man

page, meant key significance in passwords was presented incorrectly. The
typo was fixed for this update. (BZ#679530)

• Information about a new keyword -- scopev4 -- was missing from the

"gai.conf" man page. As of this update, "gai.conf(5)" now documents the
scopev4 keyword. (BZ#679894)

• The example code demonstrating how to use the getifaddrs() API in the

getifaddrs man page contained a bug capable of crashing getifaddrs if used.
The previous example code did not check for a NULL pointer under certain
conditions which would cause a segmentation fault. With this update the
example code tests for this condition, as expected, thereby avoiding the
segfault. (BZ#683039)

This update also adds the following enhancements:

• The man pages for "pwrite(v)" and "pread(v)" were previously not included

in the man page package. With this update, they are. (BZ#528546)

• The "get_mempolicy" man page was updated to be more contemporaneous with

the version of the Linux kernel (version 2.6.32) used by Red Hat Enterprise
Linux 6.(BZ#613777)

• The "pthread_attr_setguardsize" man page was updated to include

information about glibc 2.8 changes. (BZ#634986)

All users of manual pages are advised to upgrade to this updated package,
which resolves these issues.
