Patch-ID# 101081-01 Keywords: /dev/cgsix hang 4/370 4/470 vme addressing Synopsis: SunOS 4.1.3: bogus addr access in cgsix under dbx process can hang system Date: Jun/10/93 SunOS release: 4.1.3 Unbundled Product: Unbundled Release: BugId's fixed with this patch: 1123638 Architectures for which this patch is available: sun4 Patches which may conflict with this patch: Obsoleted by: Problem Description: If a process running under dbx makes an invalid address access in /dev/cgsix it will hang the system when you try to print the value of (invalid) addr. The hang will occur because dbx tries to be helpful and display a portion of what is found at addr. If you use the correct address for the mmap, everything works as expected. INSTALL: dbx may be placed in any directory provided that the directory is included in the PATH environment variable. To install where the bundled dbx goes: 1) su 2) mv /usr/ucb/dbx /usr/ucb/dbx.FCS 3) cp dbx /usr/ucb/dbx
