Patch_SG0002064_Release_Note This release note describes patch SG0002064 to IRIX 5.3. 1.1 Supported_Hardware_Platforms This patch contains bug fixes for all platforms. The software cannot be installed on other configurations. 1.2 Supported_Software_Platforms This patch contains bug fixes for IRIX 5.3 for all platforms. The software cannot be installed on other configurations. This patch replaces patches SG0000231, SG0000342, SG0001335 and SG0001479. 1.3 Bugs_Fixed_by_Patch_SG0002064 This patch contains a security bug fixes for Patch SG0001479. plus the following bug in IRIX 5.3. Bug numbers from Silicon Graphics bug tracking system are included for reference. o Bug #482870 -- When running a setuid/setgid program rld could be tricked into creating a security hole. Now rld ignores the -log option of the _RLD_ARGS environment variable for setuid/setgid programs unless the real user is root (in addition, rld continues to ignore some environment variables when handling setuid/setgid programs run by non-root users to avoid security holes). Patch SG0001479 (the previous patch) contained the following bug fixes. o Bug #250597 -- rld missing last symbol when relocating dlopen'ed DSO's. What actually happened was that rld was resolving symbols for dlopen'ed DSO's incorrectly when a previous dlsym returned a zero value. This bug was seen when running Wavefront. o Bug #258422 -- rld would block in a multi-threaded, context when one thread attempted a dlopen of a shared object which then had initialization code that required use of a lazy text resolution. This manifested it self as a hang when certain plugins were requested in a particular order. o Bug #361758 -- rld loops when 2 delay-loaded libraries are linked into the same executable and the 2 libraries are inter-dependent on each other. Also, the - 2 - performance of the libdl routines are not acceptable in big applications when hundreds of libraries are loaded using dlopen calls. o Bug #337982 -- Specifying LD_LIBRARY_PATH with more than approximately 500 characters causes rld to dump core. o Bug #364118 -- rld loops in dlsym call. o Bug #290198 -- rld loops when dlopen'ing libraries that have inter-dependencies. o Bug #402975 -- memory leak in rld when performing dlopen/dlclose. 1.4 Subsystems_Included_in_Patch_SG0002064 This patch release includes these subsystems: o patchSG0002064.compiler_eoe_sw.unix 1.5 Installation_Instructions Because you want to install patches for only the problems you have encountered, patch software is not installed by default. After reading the descriptions of the bugs fixed in this patch, determine the patches that meet your specific needs. Patch software is installed like any other Silicon Graphics software product. Follow the instructions in your IRIS Software Installation Guide to bring up the miniroot form of the software installation tools. Follow these steps to select a patch for installation: 1. At the Inst>prompt, type install patchSGxxxxxxx where xxxxxxx is the patch number. 2. Select the desired patches for installation. 3. Initiate the installation sequence. Type Inst> go - 3 - 4. You may find that two patches have been marked as incompatible. If this occurs, you must deselect one of the patches. Inst> keep patchSGxxxxxxx where xxxxxxx is the patch number. 5. After completing the installation process, exit the inst program by typing Inst> quit To remove a patch, use the versions remove command as you would for any other software subsystem. The removal process reinstates the original version of software unless you have specifically removed the patch history from your system. versions remove patchSGxxxxxxx where xxxxxxx is the patch number. To keep a patch but increase your disk space, use the versions removehist command to remove the patch history. versions removehist patchSGxxxxxxx where xxxxxxx is the patch number.
