Patch_SG0001128_Release_Note This release note describes patch SG0001128 to IRIX 5.3. 1.1 Supported_Hardware_Platforms This patch contains bug fixes for all hardware 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 hardware platforms. The software cannot be installed on other configurations. 1.3 Bugs_Fixed_by_Patch_SG0001128 This patch contains fixes for the following bugs in IRIX 5.3. Bug numbers from Silicon Graphics bug tracking system are included for reference. o An option has been added to rpc.lockd(1M) to support file locking between UNIX machines and DOS machines running PC-NFS and compatible file sharing utilities. Normally, UNIX and DOS lock requests are both handled by rpc.lockd with seperate-but-equal mechanisms; hence it is possible for a DOS machine and a UNIX machine to both lock the same file. With the new option, rpc.lockd sets an SVID-compatible lock in response to a DOS SHARE requests, so that UNIX clients recognize DOS locks and vice-versa. (RFE 235334) o As assertion failure in rpc.lockd has been corrected. (BUG 265699) o The NLM procedure NLM_TEST has been fixed. Previously, it always returned a system error. (BUG 276896) o rpc.statd(1M) has been corrected to discard hosts for which gethostbyname(3N) fails during the crash notification process. o The internal lock bookkeeping done by rpc.lockd has been reworked to eliminate inconsistencies which result in assertion failures. (BUG 322801) Race conditions involving lock cancels for blocked locks have been corrected. The handling of crash indications has been reworked to ensure the proper release of locks for crashed clients and to eliminate internal inconsistencies. - 2 - o Under some circumstances, lockd would attempt to respond to a lock request using tcp when it should have used udp. This has been corrected. o Both lockd and statd exhibit a security vulnerability described in CERT VU 15781. Through the SM_MON RPC call, a client could cause system file such as /etc/passwd to be deleted. (BUG 340903) 1.4 Subsystems_Included_in_Patch_SG0001128 This patch release includes these subsystems: o patchSG0001128.eoe1_sw.unix o patchSG0001128.nfs_man.nfs o patchSG0001128.nfs_sw.nfs 1.5 Installation_Instructions Because you want to install only the patches for problems you have encountered, patch software is not installed by default. After reading the descriptions of the bugs fixed in this patch (see Section 1.3), determine the patches that meet your specific needs. If, after reading Sections 1.1 and 1.2 of these release notes, you are unsure whether your hardware and software meet the requirements for installing a particular patch, run inst. Patch software is installed like any other Silicon Graphics software product. Follow the instructions in your Software Installation Administrator's 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.
