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.

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.

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.

Regenerated the parser after "genksyms: Track changes to enum constants". Signed-off-by: NMichal Marek <mmarek@suse.cz> Acked-by: NSam Ravnborg <sam@ravnborg.org>

由 Michal Marek 提交于
Enum constants can be used as array sizes; if the enum itself does not appear in the symbol expansion, a change in the enum constant will go unnoticed. Example patch that changes the ABI but does not change the checksum with current genksyms: | enum e { | E1, | E2, |+ E3, | E_MAX | }; | | struct s { | int a[E_MAX]; | } | | int f(struct s *s) { ... } | EXPORT_SYMBOL(f) Therefore, remember the value of each enum constant and expand each occurence to <constant> <value>. The value is not actually computed, but instead an expression in the form (last explicitly assigned value) + N is used. This avoids having to parse and semantically understand whole of C. Note: The changes won't take effect until the lexer and parser are rebuilt by the next patch. Signed-off-by: NMichal Marek <mmarek@suse.cz> Acked-by: NSam Ravnborg <sam@ravnborg.org>

While changing our build system over to use the headers_install target as part of our klibc build, the following message started showing up in our logs: make[2]: `scripts/unifdef' is up to date. It turns out that the build blindly invokes a recursive make on this target, which causes make to emit this message when the target is already up to date. This isn't seen for most targets as the rest of the build relies primarily on the default target and on PHONY targets when invoking make recursively. Silence the above message when building unifdef as part of headers_install by hiding it behind a new PHONY target called "build_unifdef" that has an empty recipe.

Add a 'W=1' Makefile switch which adds additional checking per build object. The idea behind this option is targeted at developers who, in the process of writing their code, want to do the occasional make W=1 [target.o] and let gcc do more extensive code checking for them. Then, they could eyeball the output for valid gcc warnings about various bugs/discrepancies which are not reported during the normal build process.

This implements the API defined in <linux/decompress/generic.h> which is used for kernel, initramfs, and initrd decompression. This patch together with the first patch is enough for XZ-compressed initramfs and initrd; XZ-compressed kernel will need arch-specific changes. The buffering requirements described in decompress_unxz.c are stricter than with gzip, so the relevant changes should be done to the arch-specific code when adding support for XZ-compressed kernel. Similarly, the heap size in arch-specific pre-boot code may need to be increased (30 KiB is enough). The XZ decompressor needs memmove(), memeq() (memcmp() == 0), and memzero() (memset(ptr, 0, size)), which aren't available in all arch-specific pre-boot environments. I'm including simple versions in decompress_unxz.c, but a cleaner solution would naturally be nicer. Signed-off-by: NLasse Collin <lasse.collin@tukaani.org> Cc: "H.

In userspace, the .lzma format has become mostly a legacy file format that got superseded by the .xz format. Similarly, LZMA Utils was superseded by XZ Utils. These patches add support for XZ decompression into the kernel. Most of the code is as is from XZ Embedded <http://tukaani.org/xz/embedded.html>. It was written for the Linux kernel but is usable in other projects too. Advantages of XZ over the current LZMA code in the kernel: - Nice API that can be used by other kernel modules; it's not limited to kernel, initramfs, and initrd decompression. - Integrity check support (CRC32) - BCJ filters improve compression of executable code on certain architectures. These together with LZMA2 can produce a few percent smaller kernel or Squashfs images than plain LZMA without making the decompression slower. This patch: Add the main decompression code (xz_dec), testing module (xz_dec_test), wrapper script (xz_wrap.sh) for the xz command line tool, and documentation. The xz_dec module is enough to have a usable XZ decompressor e.g. for Squashfs. Signed-off-by: NLasse Collin <lasse.collin@tukaani.org> Cc: "H.
