[Crash-utility] crash version 4.0-7.7 is available

[Dave Anderson]

- Because the ia64 and ppc64 architectures have configurable page 
  sizes, a host system running a crash session against a dumpfile may
  have a different page size than the system that generated the
  dumpfile.  If the dumpfile is a compressed kdump vmcore or a 
  diskdump vmcore, the page size will be reset to the dumpfile header's 
  block_size variable if it does not agree with the host system's page
  size.  If the dumpfile is a 64-bit kdump ELF vmcore with vmcoreinfo 
  data that includes the crashing system's page size, that page size 
  will be used if the architecture is an ia64 or ppc64.

- Fix for "mod -[sS]" command if the target module object filename
  contains both underscore and dash characters.  Without the patch
  the module load would fail with the error message: "mod: cannot 
  find or load object file for <name> module".  Examples are
  the "aes_x86_64" module from the "aes-x86_64.ko" object file, and
  the "dm_region_hash" module from the "dm-region_hash.ko" object file.

- Reject s390 and s390x "L2^B" local label symbols from the kernel 
  symbol list.  (bwalle at suse.de)

- Enlarge the string format buffer in the show_last_run() function to
  prevent a buffer overflow when running "ps -l".

- Fix for "bt -a" to continue with the backtraces of the remaining
  active tasks when one of them encounters a fatal error.  Without 
  the patch, the command is aborted when any of the backtraces fail.

- Only allow trusted versions of .crashrc and .gdbinit files to be
  sourced during session initialization.  (anderson at redhat.com)

- Fix for a potential but highly unlikely buffer overflow in the gdb 
  dwarfread.c and dwarf2read.c files, which requires a hand-crafted 
  object file with a location block (DW_FORM_block) that contains a 
  large number of operations.  (anderson at redhat.com)

- Fix for a potential but highly unlikely integer overflow in the 
  Binary File Descriptor (BFD) library, which requires a hand-crafted
  object file that that specifies a large number of section headers,
  leading to a heap-based buffer overflow.  (anderson at redhat.com)
        
- Enable stack unwind on ia64 when using a kerntypes file as the 
  kernel namelist.  (cpw at sgi.com)

- Fix for failure of "files -R" command option if an inode is unknown 
  due to a NULL f_dentry pointer in any open file structure because of
  a kernel error condition.  Without the patch, the command aborts 
  prematurely with the error message: "files: invalid input: ?".

- Allow an LKCD kerntypes debuginfo file created from a kernel module 
  to be loaded with the command: "mod -s <module> <kerntypes-file>".  
  (cpw at sgi.com)

- Increased NR_CPUS from 256 to 512 for x86_64, and from 128 to 1024 
  for ppc64.  Made several NR_CPUS-bound static arrays in the internal 
  task_table and kernel_table structures dynamically allocated only 
  upon demand.  (anderson at redhat.com)
