Package: crash (4.0-3.4-1)

kernel debugging utility, allowing gdb like syntax

The core analysis suite is a self-contained tool that can be used to investigate either live systems, LKCD (Linux Kernel Crash Dumps) and Red Hat Netdump and Diskdump core dumps.

For complete LKCD crash dump support you will need the LKCD kernel patch, dumputils, and a debugger that can be used to analyze the crash, such as the "lcrash" or "crash" (this package) packages.

o The tool is loosely based on the SVR4 crash command, but has been

   completely integrated with gdb in order to be able to display
   formatted kernel data structures, disassemble source code, etc.

o The current set of available commands consist of common kernel core

   analysis tools such as a context-specific stack traces, source code
   disassembly, kernel variable displays, memory display, dumps of
   linked-lists, etc.  In addition, any gdb command may be entered,
   which in turn will be passed onto the gdb module for execution.

o There are several commands that delve deeper into specific kernel

   subsystems, which also serve as templates for kernel developers
   to create new commands for analysis of a specific area of interest.
   Adding a new command is a simple affair, and a quick recompile
   adds it to the command menu.

o The intent is to make the tool independent of Linux version dependencies,

   building in recognition of major kernel code changes so as to adapt to
   new kernel versions, while maintaining backwards compatibility.
