kconfig: Avoid buffer underrun in choice input

2011-04-24T15:24:31Z

Commit 40aee729b350 ('kconfig: fix default value for choice input') fixed some cases where kconfig would select the wrong option from a choice with a single valid option and thus enter an infinite loop. However, this broke the test for user input of the form 'N?', because when kconfig selects the single valid option the input is zero-length and the test will read the byte before the input buffer. If this happens to contain '?' (as it will in a mips build on Debian unstable today) then kconfig again enters an infinite loop.

bloat-o-meter: include read-only data section in report

2011-03-23T00:44:17Z

I'm not sure why the read-only data section is excluded from the report, it seems as relevant as the other data sections (b and d). I've stripped the symbols starting with __mod_ as they can have their names dynamically generated and thus comparison between binaries is not possible.

checkpatch: warn about memset with swapped arguments

2011-03-23T00:44:15Z

Because the second and third arguments of memset have the same type, it turns out to be really easy to mix them up. This bug comes up time after time, so checkpatch should really be checking for it at patch submission time.

scripts/checkpatch.pl: reset rpt_cleaners warnings

2011-03-23T00:44:15Z

If you run checkpatch against multiple patches, and one of them has a whitespace issue which can be helped via a script (rpt_cleaners), you will see the same NOTE over and over for all subsequent patches. It makes it seem like those patches also have whitespace problems when in reality, there's only one or two bad apples. So reset rpt_cleaners back to 0 after we've issued the note so that it only shows up near the patch with the actual problems.

kstrto*: converting strings to integers done (hopefully) right

2011-03-23T00:44:14Z

1. simple_strto*() do not contain overflow checks and crufty, libc way to indicate failure. 2. strict_strto*() also do not have overflow checks but the name and comments pretend they do. 3. Both families have only "long long" and "long" variants, but users want strtou8() 4. Both "simple" and "strict" prefixes are wrong: Simple doesn't exactly say what's so simple, strict should not exist because conversion should be strict by default. The solution is to use "k" prefix and add convertors for more types. Enter kstrtoull() kstrtoll() kstrtoul() kstrtol() kstrtouint() kstrtoint() kstrtou64() kstrtos64() kstrtou32() kstrtos32() kstrtou16() kstrtos16() kstrtou8() kstrtos8() Include runtime testsuite (somewhat incomplete) as well. strict_strto*() become deprecated, stubbed to kstrto*() and eventually will be removed altogether. Use kstrto*() in code today! Note: on some archs _kstrtoul() and _kstrtol() are left in tree, even if they'll be unused at runtime. This is temporarily solution, because I don't want to hardcode list of archs where these functions aren't needed. Current solution with sizeof() and __alignof__ at least always works.

get_maintainer.pl: allow "K:" pattern tests to match non-patch text

2011-03-23T00:44:13Z

Extend the usage of the K section in the MAINTAINERS file to support matching regular expressions to any arbitrary text that may precede the patch itself. For example, the commit message or mail headers generated by git-format-patch. Signed-off-by: Joe Perches Original-patch-by: L. Alberto Giménez Acked-by: L.
