d2b6b7b0a7 Fix bad pointer usage in xsparse.c 
* scripts/xsparse.c (read_xheader): Avoid undefined behavior by
accessing via null pointer sparse_map or out of its bounds when
the input is invalid.  This means we no longer need the ‘expect’
local, so omit it for simplicity.

9bbcac1cf7 Port xsparse.c to AIX 
* scripts/xsparse.c (emalloc): Do not report failure when malloc
(0) returns NULL, as it does on AIX.  Simply return a null
pointer; that’s good enough for xsparse.c.

ac06d4d104 Fix xsparse.c big heap allocation bugs 
* scripts/xsparse.c (expand_sparse): Read into auto buffer, not heap.
The heap code was wrong for two reasons: it called malloc just once
in the try-again loop, and even when it succeeded it could have
left so few bytes available in the heap that later stdio calls
could fail.  Reading into the auto buffer might be a bit slower
but speed is not an issue here and it’s better to be simple.

88c2aa1616 Fix minor integer overflow in xsparse.c 
* scripts/xsparse.c (read_xheader):
Don’t assume size_t fits in unsigned.
Make the version numbers off_t, not just unsigned.

9cb1293628 xsparse dry runs should not create output 
* scripts/xsparse.c (expand_sparse, main): Check for syscall
failure.  Do not create output file if a dry run.

44196e198f Better xsparse outname guessing 
* scripts/xsparse.c (guess_outname): Use simpler algorithm,
that doesn’t mishandle outnames like ‘/foo’.

b26e798a0f xsparse cleanup, including integer overflow 
* scripts/xsparse.c: Include inttypes.h, for strtoimax.
Don’t include stdint.h, since inttypes.h includes it.
Sort include directives.
Make all extern functions and vars static, except for ‘main’.
(string_to_off): Use strtoimax instead of doing overflow
checking by hand, incorrectly (it relied on undefined behavior).
(string_to_size): New arg MAXSIZE.  All callers changed.
(get_var): Return bool not int.  Fix unlikely integer overflow.
Use strncmp instead of memcmp, to avoid unlikely pointer overflow.
(read_xheader, read_map, main): Avoid unlikely integer overflow.
Check for I/O errors more consistently.
(main): Prefer bool to int, and put vars near use.

debc485626 tar: quote 'like this', not `like this'

Remove trailing spaces and tabs from lines, and remove
trailing empty lines from files.  This makes it a bit easier
to share code among coreutils and other projects that do this.

bf5ba3dbef A sample utility to expand sparse files 
extracted by third-party tars. It is not meant to be installed nor
to be included in the distribution. It is here, so that it can be
obtained either from CVS or from the tar web site.
