Patch Installation instructions:
-------------------------------
The libraries in this patch may be placed in any directory.  But if you
choose to place any libc.* in a location other than /usr/lib or
/usr/5lib, you'll have to use the -L flag with each ld execution to
"point" to the chosen directory that holds these substitutes.  Since
this is likely to be a somewhat awkward requirement, the patch and the
following install sequence assume you wish to substitute your standard
libraries with the patched versions.
 
The installation of ANY of the library parts may be done while the
system is running, EXCEPT for the SHARED libc's.  It is SAFEST to
substitute the shared libraries while SunOS is booted in single-user
mode or from the SunOS Installation miniroot.  Since using SunOS in
single-user mode is easier than booting the miniroot off the SunOS
Installation tapes, the install sequence below will reference
single-user mode.
 
There is one more consideration.  The installation sequence below will
overwrite ALL libc "variants" in /usr/lib and /usr/5lib.  If you have
added/substituted parts to libc.a or libc.s?.X.Y in /usr/lib and/or
/usr/5lib, you will need to 1) preserve these copies, or 2) plan to
resubstitute your material in with these patch versions.
 
It is highly recommended that you "walkthru" the installation sequence
below to become familiar with what is being done prior to actually
doing it.  You can vary and even skip some steps in these instructions
if you're *confident* you understand what is going on.  Bear in mind that
/usr/lib/libc.so.X.Y dynamically binds the *entire* SunOS and any
corruption to this particular library will render a system virtually
useless.

 
Installing the libc patch:  (perform the following steps in this order)
 
        o save patch distribution under some directory, say '/tmp/X'.
          (if in tar format  untar using tar xpf &lt;patch_archive&gt;.tar)
        o cd /tmp/X
        o su
        o (ensure no users are actively using any libc's)
        o mv /usr/lib/libc.a /usr/lib/libc.a.FCS
        o mv /usr/lib/libc_p.a /usr/lib/libc_p.a.FCS    (1)
        o mv /usr/5lib/libc.a /usr/5lib/libc.a.FCS      (2)
        o mv /usr/5lib/libc_p.a /usr/5lib/libc_p.a.FCS  (2)
        o mv /usr/lib/libbsdmalloc.a /usr/lib/libbsdmalloc.a.FCS
 
        (1) if you do not have this file on your system, then the
        "Debugging" part of the OS distribution tape has not been
        loaded.
 
        (2) if you do not have this file on your system, then the
        "SystemV" part of the OS distribution tape has not been
        loaded.
 
You will rename your original shared libc's at a later point in the
installation.
 
        o mv /usr/lib/shlib.etc /usr/lib/shlib.etc.FCS
        o mkdir /usr/lib/shlib.etc
        o chmod 2755 /usr/lib/shlib.etc
 
These above 3 steps may be done if you wish to preserve completely your
original /usr/lib/shlib.etc.  If not, you may skip them.
 
        o mv /usr/lib/debug /usr/lib/debug.FCS
        o mkdir /usr/lib/debug
        o chmod 2755 /usr/lib/debug
 
These above 3 steps may be done if you wish to preserve completely your
original /usr/lib/debug.  If not, you may skip them.
 
	o cp -p -R lib/*  /usr/lib
	o cp -p -R 5lib/* /usr/5lib 
 
You are actually copying all the files in lib and 5lib directories
to /usr/lib and /usr/5lib. If you followed all steps mentioned above you
are still in /tmp/X.
 
        o "quiet" system  (have users log off, announce system going down)
        o sync
        o halt
        o &gt;b[oot] vmunix -s
 
You're now booting SunOS in single-user mode.  We will rename the shared
libc's to make them "active" and this is best done, at minimum, under
single-user.

 
        o cd /usr/lib
        o ls -l libc.s*
 
                You will get an output similar to the following:
 
	-rw-r--r--  1 root         7996 Oct 13 19:02 /usr/lib/libc.sa.1.9
	-rwxr-xr-x  1 root       516096 Oct 13 19:02 /usr/lib/libc.so.1.9
	-rw-r--r--  1 root         7996 Jan 11 08:49 /usr/lib/libc.sa19
	-rwxr-xr-x  1 root       516096 Jan 11 08:24 /usr/lib/libc.so19

        o sync
        o mv libc.so.1.9 libc.so.1.9.FCS     this saves the original file
 
        o mv libc.so19 libc.so.1.9           this copies the patch to its
                                             new place
 
        o mv libc.sa.1.9 libc.sa.1.9.FCS     this saves the original file
 
        o mv libc.sa19 libc.sa.1.9           this copies the patch to its
                                             new place
 
        o date
 
Do this last step CAREFULLY.  IF the 'date' command does *anything*
else but show a proper date, then IMMEDIATELY do:
 
        o mv libc.so.1.9 libc.so19
        o mv libc.so.1.9.FCS libc.so.1.9
        o mv libc.sa.1.9 libc.sa19
        o mv libc.sa.1.9.FCS libc.sa.1.9
 
If the date command is successful, continue here:
 
        o cd ../5lib
        o ls -l libc.s*
 
                You will get an output similar to the following:
 
	-rw-r--r--  1 root         7996 Oct 13 19:02 /usr/5lib/libc.sa.2.9
	-rw-r--r--  1 root       524288 Oct 13 19:02 /usr/5lib/libc.so.2.9
	-rw-r--r--  1 root         7996 Jan 11 08:49 /usr/5lib/libc.sa29
	-rw-r--r--  1 root       524288 Jan 11 08:24 /usr/5lib/libc.so29

 
        o mv libc.so.2.9 libc.so.2.9.FCS     this saves the original file
 
        o mv libc.so29 libc.so.2.9           this copies the patch to its
                                             new place
 
        o mv libc.sa.2.9 libc.sa.2.9.FCS     this saves the original file
 
 
        o mv libc.sa29 libc.sa.2.9           this copies the patch to its
                                             new place
 
Do this last step CAREFULLY also.
 
        o ranlib -t /usr/lib/libc*a*

        o ranlib -t /usr/5lib/libc*a*

        o ranlib -t /usr/lib/libbsdmalloc.a

        o ^D
 
The install is complete.  The ^D above terminates single-user mode, and
brings your system back up in multi-user mode.
