lib: hex2bin converts ascii hexadecimal string to binary

2010-11-28T21:55:11+00:00

Similar to the kgdb_hex2mem() code, hex2bin converts a string
to binary using the hex_to_bin() library call.

Changelog:
- Replace parameter names with src/dst (based on David Howell's comment)
- Add 'const' where needed (based on David Howell's comment)
- Replace int with size_t (based on David Howell's comment)

lib: introduce common method to convert hex digits

2010-05-25T15:07:05+00:00

hex_to_bin() is a little method which converts hex digit to its actual
value.  There are plenty of places where such functionality is needed.

[akpm@linux-foundation.org: use tolower(), saving 3 bytes, test the more common case first - it's quicker]
[akpm@linux-foundation.org: relocate tolower to make it even faster! (Joe)]

lib/hexdump.c: reduce stack variable size and cleanups

2010-05-25T15:07:05+00:00

Reduce char linebuf[200] to the actual size required., which is 32 * 3 + 2
+ 32 + 1, ie: linebuf[131].

Change examples to use bool true not int 1.

Align multiline argument indentation to open parenthesis.

Use temporary for ptr[j] so trigraph fits on single line.

Convert printk ptr from %*p, (int)(2 * sizeof(void *)) to %p as %p uses
the same calculation for size.

hexdump: remove the trailing space

2009-06-17T02:47:51+00:00

For example:
        hex_dump_to_buffer("AB", 2, 16, 1, buf, 100, 0);
        pr_info("[%s]\n", buf);

I'd expect the output to be "[41 42]", but actually it's "[41 42 ]"

This patch also makes the required buf to be minimum.  To print the hex
format of "AB", a buf with size 6 should be sufficient, but
hex_dump_to_buffer() required at least 8.

lib: create common ascii hex array

2008-05-15T02:11:14+00:00

Add a common hex array in hexdump.c so everyone can use it.

Add a common hi/lo helper to avoid the shifting masking that is
done to get the upper and lower nibbles of a byte value.

Pull the pack_hex_byte helper from kgdb as it is opencoded many
places in the tree that will be consolidated.

hexdump: don't print bytes with bit 7 set

2007-11-29T17:24:53+00:00

As Herbert Xu pointed out, bytes (chars) with bit 7 (0x80) set are true
with isprint() but they may not be isascii() but be Unicode instead, so
don't try to print them in hex dumps.

hex_dump: add missing "const" qualifiers

hexdump: use const notation

2007-08-09T15:34:23+00:00

Trivial fix: mark the buffer to hexdump as const so callers could avoid
casting their const buffers when calling print_hex_dump().

The patch is really trivial and I suggest to consider it as a fix
(it fixes GCC warnings) and push it to current tree.

hexdump: more output formatting

2007-06-09T00:23:34+00:00

Add a prefix string parameter.  Callers are responsible for any string
length/alignment that they want to see in the output.  I.e., callers should
pad strings to achieve alignment if they want that.

Add rowsize parameter.  This is the number of raw data bytes to be printed
per line.  Must be 16 or 32.

Add a groupsize parameter.  This allows callers to dump values as 1-byte,
2-byte, 4-byte, or 8-byte numbers.  Default is 1-byte numbers.  If the
total length is not an even multiple of groupsize, 1-byte numbers are
printed.

Add an "ascii" output parameter.  This causes ASCII data output following
the hex data output.

Clean up some doc examples.

Align the ASCII output on all lines that are produced by one call.

Add a new interface, print_hex_dump_bytes(), that is a shortcut to
print_hex_dump(), using default parameter values to print 16 bytes in
byte-size chunks of hex + ASCII output, using printk level KERN_DEBUG.
