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'. 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 >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 Feb 8 1990 libc.sa.1.8 -rwxr-xr-x 1 root 516096 Feb 8 1990 libc.so.1.8 -rw-r--r-- 1 root 7996 Oct 4 05:00 libc.sa18 -rw-r--r-- 1 root 516096 Oct 4 05:13 libc.so18 o sync o mv libc.so.1.8 libc.so.1.8.FCS this saves the original file o mv libc.so18 libc.so.1.8 this copies the patch to its new place o mv libc.sa.1.8 libc.sa.1.8.FCS this saves the original file o mv libc.sa18 libc.sa.1.8 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.1.8 libc.so18 o mv libc.so.1.8.FCS libc.so.1.8 o mv libc.sa.1.8 libc.sa18 o mv libc.sa.1.8.FCS libc.sa.1.8 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 Feb 8 1990 libc.sa.2.8 -rwxr-xr-x 1 root 516096 Feb 8 1990 libc.so.2.8 -rw-r--r-- 1 root 7996 Oct 4 05:00 libc.sa28 -rw-r--r-- 1 root 524288 Oct 4 05:15 libc.so28 o mv libc.so.2.8 libc.so.2.8.FCS this saves the original file o mv libc.so28 libc.so.2.8 this copies the patch to its new place o mv libc.sa.2.8 libc.sa.2.8.FCS this saves the original file o mv libc.sa28 libc.sa.2.8 this copies the patch to its new place Do this last step CAREFULLY also. o ranlib -t /usr/lib/libc* o ranlib -t /usr/5lib/libc* o ^D The install is complete. The ^D above terminates single-user mode, and brings your system back up in multi-user mode. <<<<<<<<<<<<<<<<<< end README >>>>>>>>>>>>>>>>>>>>>>
