PROBLEM:
What is libc version 8.0.2k, the UnixWare 7 Definitive Runtime C Library
package?  What problems are fixed, what is its contents, how to install this
package, and are there additional software notes?

SOLUTION:

Problems Fixed
--------------

  libc, version 8.0.2f, shipped with the original UnixWare 7 Definitive 2018
  release.  libc, version 8.0.2k, includes all the fixes in libc versions
  8.0.2g, 8.0.2h, 8.0.2i, and 8.0.2j as well as an additional fixes.

  Fixed in libc, version 8.0.2g:

  1.  Revisions to header files and libraries to correct some of the stdio
      helper functions.  These functions were provided in prior releases to
      aid in open source porting.  These functions were modified:
         __freadable()
         __fwritable()
         __fbufsiz() should have been __fbufsize()

      This fix is provided partially by this libc package and partially by
      PTF 9150 (version f or later) or any version of PTF 9151.

      UW7-173

  Fixed in libc, version 8.0.2h:

  2.  Corrected LD_PRELOAD so, when used, loads the libraries set by
      LD_PRELOAD prior to any other libraries, including libc.so.1.

      UW7-183

  Fixed in libc, version 8.0.2i:

  3.  The getprogname and setprogname functions are now in libc.
      Also cleaned up a typdef redeclaration warning.

      This fix is provided partially by this libc package and partially by
      PTF 9150 (version h or later) and in PTF9151 (all versions).

      UW7-146

  Changes and fixes in libc, version 8.0.2j:
  UW7-146, UW7-147

  4.  Improve mktemp() and mkstemp().

  5.  Add mkdtemp(), mkostemp(), mkostemps(), mkstemps(), arc4random(),
      arc4random_buf(), arc4random_uniform(), getentropy, and
      explicit_bzero().

  6.  Add _SC_LOGIN_NAME_MAX and _SC_HOST_NAME_MAX, _SC_TTY_NAME_MAX,
      to sysconf().

  7.  Add _SC_GETGR_R_SIZE_MAX, and _SC_GETPW_R_SIZE_MAX to sysconf().

  8.  Add hooks to clock_getres(), clock_gettime(), clock_settime(), and
      clock_nanosleep() syscalls.

  9.  Add nanosleep().

  10.  Add clock_gettime() using interpolate like gettimeofday().

  11.  Enhance realpath() and add canonicalize_file_name().

  12.  Update sysconf for TTY_NAME_MAX, add posix_memalign() and memmem()

  13.  Add getopt_long(), getopt_long_only(), err(), err_set_exit(),
       err_set_file(), errc(), errx(), verr(), verrc(), verrx(), vwarn(),
       vwarnc(), vwarnx(), warn(), warnc(), warnx().

  14.  Keep setlocale() from core dumping when passed a category
       greater than LC_ALL.

  15.  Add dirfd(), strsep(), execvpe(), posix_spawn(), posix_spawnp(),
       posix_spawn_file_actions_init(), posix_spawn_file_actions_destroy(),
       posix_spawn_file_actions_addopen(), posix_spawn_file_actions_adddup2(),
       posix_spawn_file_actions_addclose(), posix_spawnattr_init(),
       posix_spawnattr_destroy(), posix_spawnattr_getflags(),
       posix_spawnattr_getpgroup(), posix_spawnattr_getschedparam(),
       posix_spawnattr_getschedpolicy(), posix_spawnattr_getsigdefault(),
       posix_spawnattr_getsigmask(), posix_spawnattr_setflags(),
       posix_spawnattr_setpgroup(), posix_spawnattr_setschedparam(),
       posix_spawnattr_setschedpolicy(), posix_spawnattr_setsigdefault(),
       posix_spawnattr_setsigmask(), and fdopendir().
       Add getdelim(), and getline().

       These fixes/additions are provided partially by this libc package
       partially by libthread package and partially by PTF 9151 (version a
       or later).

  Changes and fixes in libc, version 8.0.2k:

  16.  Fixed a duplicate system call number mistakenly introduced in rev j.
       Renamed some variables in clock_gettime to avoid potential name space
       clash. No change in functionality.

Installation Instructions
-------------------------

Either use patchck to install this package or use the following procedure:

  1. Download the libc.8.0.2k.image file to the /tmp directory on your machine.

  2. As root, add the package to your system using these commands:

     $ su -
     Password: <type your root password>
     # pkgadd -d /tmp/libc.8.0.2k.image all

     Alternatively, this package may be installed in quiet mode, that is,
     without displaying the release notes and asking for confirmation.
     To do this, use these commands:

     $ su -
     Password: <type your root password>
     # pkgadd -qd /tmp/libc.8.0.2k.image all

  3. If you are installing multiple packages, you do not need to reboot
     the system immediately after installing this libc package.  Any
     currently running application using the previous C runtime will
     continue to do so until the application terminates or the system is
     rebooted.  When done installing packages, rebooting is recommended.
     Rebooting is necessary after installing ptf9151.  (See the Software Notes
     and Recommendations section below.)


Software Notes and Recommendations
----------------------------------

  1.  libc, version 8.0.2k, should only be installed on:

      UnixWare 7 Definitive 2018 (D2M1)

  2.  The libc package, once installed, cannot be back revved to an earlier
      version.

  3.  To use new capabilities provided with this version of libc, you also
      need to install updated:
         libthread package version 8.0.2d or later
         ptf9151 package version b or later

      These three companion packages (libc, libthread, and ptf9151) must each
      be installed with compatible versions of the other two.

      Immediately after installing this libc package, install the libthread
      package and then ptf9151.  Reboot your system immediately after all
      three packages are installed.
