strcmp: fix overflow and possibly signedness error

2009-11-19T01:18:13+00:00

Doing the strcmp return value as

	signed char __res = *cs - *ct;

is wrong for two reasons.  The subtraction can overflow because __res
doesn't use a type big enough.  Moreover the compared bytes should be
interpreted as unsigned char as specified by POSIX.

The same problem is fixed in strncmp.

Add a new sysfs_streq() string comparison function

2008-05-01T15:03:59+00:00

Add a new sysfs_streq() string comparison function, which ignores
the trailing newlines found in sysfs inputs.  By example:

	sysfs_streq("a", "b")	==> false
	sysfs_streq("a", "a")	==> true
	sysfs_streq("a", "a\n")	==> true
	sysfs_streq("a\n", "a")	==> true

This is intended to simplify parsing of sysfs inputs, letting them
avoid the need to manually strip off newlines from inputs.

[PATCH] Numerous fixes to kernel-doc info in source files.

2007-02-11T18:51:32+00:00

A variety of (mostly) innocuous fixes to the embedded kernel-doc content in
source files, including:

  * make multi-line initial descriptions single line
  * denote some function names, constants and structs as such
  * change erroneous opening '/*' to '/**' in a few places
  * reword some text for clarity

[PATCH] strstrip remove last blank fix

2006-10-28T18:30:54+00:00

strstrip() does not remove the last blank from strings which only consist
of blanks.

Example:
char string[] = "  ";
strstrip(string);

results in " ", but should produce an empty string!

The following patch solves this problem:

[PATCH] Clean up arch-overrides in linux/string.h

2006-04-11T13:18:40+00:00

Some string functions were safely overrideable in lib/string.c, but their
corresponding declarations in linux/string.h were not.  Correct this, and
make strcspn overrideable.

Odds of someone wanting to do optimized assembly of these are small, but
for the sake of cleanliness, might as well bring them into line with the
rest of the file.

[PATCH] No arch-specific strpbrk implementations

2006-04-11T13:18:40+00:00

While cleaning up parisc_ksyms.c earlier, I noticed that strpbrk wasn't
being exported from lib/string.c.  Investigating further, I noticed a
changeset that removed its export and added it to _ksyms.c on a few more
architectures.  The justification was that "other arches do it."

I think this is wrong, since no architecture currently defines
__HAVE_ARCH_STRPBRK, there's no reason for any of them to be exporting it
themselves.  Therefore, consolidate the export to lib/string.c.

[PATCH] multiple exports of strpbrk

2006-03-22T15:53:56+00:00

Sam's tree includes a new check, which found that we're exporting strpbrk()
multiple times.

It seems that the convention is that this is exported from the arch files, so
reove the lib/string.c export.
