* markup_oops.pl: fix $func_offset error with x86_64Hui Zhu2010-02-02

* modpost: fix segfault in sym_is() with prefixed archesMike Frysinger2010-01-17
| | | | | | | | | | | | | | | | | | | | | | | The sym_is() compares a symbol in an attempt to automatically skip symbol prefixes. It does this first by searching the real symbol with the normal unprefixed symbol. But then it uses the length of the original symbol to check the end of the substring instead of the length of the symbol it is looking for. On non-prefixed arches, this is effectively the same thing, so there is no problem. On prefixed-arches, since this is exceeds by just one byte, a crash is rare and it is usually a NUL byte anyways. But every once in a blue moon, you get the right page alignment and it segfaults. For example, on the Blackfin arch, sym_is() will be called with the real symbol "___mod_usb_device_table" as "symbol" when looking for the normal symbol "__mod_usb_device_table" as "name". The substring will thus return one byte into "symbol" and store it into "match". But then "match" will be indexed with the length of "symbol" instead of "name" and so we will exceed the storage. i.e. the code ends up doing: char foo[] = "abc"; return foo[strlen(foo)+1] == '\0'; Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

* | kbuild: really fix bzImage build with non-bash shJonathan Nieder2010-01-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In an x86 build with CONFIG_KERNEL_LZMA enabled and dash as sh, arch/x86/boot/compressed/vmlinux.bin.lzma ends with '\xf0\x7d\x39\x00' (16 bytes) instead of the 4 bytes intended and the resulting vmlinuz fails to boot. This improves on the previous behavior, in which the file contained the characters '-ne ' as well, but not by much. Previous commits replaced "echo -ne" first with "/bin/echo -ne", then "printf" in the hope of improving portability, but none of these commands is guaranteed to support hexadecimal escapes on POSIX systems. So use the shell to convert from hexadecimal to octal. With this change, an LZMA-compressed kernel built with dash as sh boots correctly again.

* | lib: add support for LZO-compressed kernelsAlbin Tonnerre2010-01-11
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch series adds generic support for creating and extracting LZO-compressed kernel images, as well as support for using such images on the x86 and ARM architectures, and support for creating and using LZO-compressed initrd and initramfs images. Russell King said: : Testing on a Cortex A9 model: : - lzo decompressor is 65% of the time gzip takes to decompress a kernel : - lzo kernel is 9% larger than a gzip kernel : : which I'm happy to say confirms your figures when comparing the two. : : However, when comparing your new gzip code to the old gzip code: : - new is 99% of the size of the old code : - new takes 42% of the time to decompress than the old code : : What this means is that for a proper comparison, the results get even better: : - lzo is 7.5% larger than the old gzip'd kernel image : - lzo takes 28% of the time that the old gzip code took : : So the expense seems definitely worth the effort. The only reason I : can think of ever using gzip would be if you needed the additional : compression (eg, because you have limited flash to store the image.) : : I would argue that the default for ARM should therefore be LZO. This patch: The lzo compressor is worse than gzip at compression, but faster at extraction. Here are some figures for an ARM board I'm working on: Uncompressed size: 3.24Mo gzip 1.61Mo 0.72s lzo 1.75Mo 0.48s So for a compression ratio that is still relatively close to gzip, it's much faster to extract, at least in that case. This part contains: - Makefile routine to support lzo compression - Fixes to the existing lzo compressor so that it can be used in compressed kernels - wrapper around the existing lzo1x_decompress, as it only extracts one block at a time, while we need to extract a whole file here - config dialog for kernel compression [akpm@linux-foundation.org: coding-style fixes] [akpm@linux-foundation.org: cleanup] Signed-off-by: Albin Tonnerre <albin.tonnerre@free-electrons.com> Tested-by: Wu Zhangjin <wuzhangjin@gmail.com> Acked-by: "H.

| * MIPS: Tracing: Add dynamic function tracer supportWu Zhangjin2009-12-16

When enabling it in user-space, it will jump to a real tracing function(ftrace_caller), and do the real job for us. Differ from the static function tracer, dynamic function tracer provides two functions ftrace_make_call()/ftrace_make_nop() to enable/disable the tracing of some indicated kernel functions(set_ftrace_filter). In the -v4 version, the implementation of this support is basically the same as X86 version does: _mcount is implemented as an empty function and ftrace_caller is implemented as a real tracing function respectively. But in this version, to support module tracing with the help of -mlong-calls in arch/mips/Makefile: MODFLAGS += -mlong-calls. The stuff becomes a little more complex. We need to cope with two different type of calling to _mcount. For the kernel part, the calling to _mcount(result of "objdump -hdr vmlinux"). is like this: 108: 03e0082d move at,ra 10c: 0c000000 jal 0 <fpcsr_pending> 10c: R_MIPS_26 _mcount 10c: R_MIPS_NONE *ABS* 10c: R_MIPS_NONE *ABS* 110: 00020021 nop For the module with -mlong-calls, it looks like this: c: 3c030000 lui v1,0x0 c: R_MIPS_HI16 _mcount c: R_MIPS_NONE *ABS* c: R_MIPS_NONE *ABS* 10: 64630000 daddiu v1,v1,0 10: R_MIPS_LO16 _mcount 10: R_MIPS_NONE *ABS* 10: R_MIPS_NONE *ABS* 14: 03e0082d move at,ra 18: 0060f809 jalr v1 In the kernel version, there is only one "_mcount" string for every kernel function, so, we just need to match this one in mcount_regex of scripts/recordmcount.pl, but in the module version, we need to choose one of the two to match. Herein, I choose the first one with "R_MIPS_HI16 _mcount". and In the kernel verion, without module tracing support, we just need to replace "jal _mcount" by "jal ftrace_caller" to do real tracing, and filter the tracing of some kernel functions via replacing it by a nop instruction. but as we have described before, the instruction "jal ftrace_caller" only left 32bit length for the address of ftrace_caller, it will fail when calling from the module space. so, herein, we must replace something else. the basic idea is loading the address of ftrace_caller to v1 via changing these two instructions: lui v1,0x0 addiu v1,v1,0 If we want to enable the tracing, we need to replace the above instructions to: lui v1, HI_16BIT_ftrace_caller addiu v1, v1, LOW_16BIT_ftrace_caller If we want to stop the tracing of the indicated kernel functions, we just need to replace the "jalr v1" to a nop instruction. but we need to replace two instructions and encode the above two instructions oursevles. Is there a simpler solution? Yes! Here it is, in this version, we put _mcount and ftrace_caller together, which means the address of _mcount and ftrace_caller is the same: _mcount: ftrace_caller: j ftrace_stub nop ...(do real tracing here)... ftrace_stub: jr ra move ra, at By default, the kernel functions call _mcount, and then jump to ftrace_stub and return. and when we want to do real tracing, we just need to remove that "j ftrace_stub", and it will run through the two "nop" instructions and then do the real tracing job. what about filtering job? we just need to do this: lui v1, hi_16bit_of_mcount <--> b 1f (0x10000004) addiu v1, v1, low_16bit_of_mcount move at, ra jalr v1 nop 1f: (rec->ip + 12) In linux-mips64, there will be some local symbols, whose name are prefixed by $L, which need to be filtered. thanks goes to Steven for writing the mips64-specific function_regex. In a conclusion, with RISC, things becomes easier with such a "stupid" trick, RISC is something like K.I.S.S, and also, there are lots of "simple" tricks in the whole ftrace support, thanks goes to Steven and the other folks for providing such a wonderful tracing framework!

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Running "make deb-pkg" requires setting KBUILD_PKG_ROOTCMD or becoming root oneself or it errors out. Unless already running as root or KBUILD_PKG_ROOTCMD is already set, use fakeroot as a good default. With this patch applied, you can run "make oldconfig deb-pkg" as an ordinary user to build a binary package for an updated kernel tree and it should just work. fakeroot is too zealous by default in treating files as owned by root. Its wrapped stat() sets st_uid and st_gid to 0 for all files, which causes Git to go on a wild goose chase if CONFIG_LOCALVERSION_AUTO is set, checking if any file's content has changed along with its stat information. Avoid this by telling fakeroot to use the actual owner and group for preexisting files, by passing it the -u option.

Without such privileges, deb-pkg errors out because chown fails. The new KBUILD_PKG_ROOTCMD variable, if defined, is used as a command to run other commands with possibly fake elevated privileges. Since this is not needed for the tar-pkg and rpm-pkg targets, it is only used by deb-pkg. If it is not defined, the behavior is as before, and the user will have to rerun make as root. In other words, as a shortcut, instead of running 'make oldconfig && make && fakeroot -u make deb-pkg', one can use the single command 'make oldconfig deb-pkg KBUILD_PKG_ROOTCMD="fakeroot -u"'.

What should be used here is printf(1). The trivial patch below (on top of these kbuild changes) fixes this issue.

Currently it is mixed in with C structure definitions in "asm/module.h". Move the definition of this arch option into Kconfig, so it can be easily accessed by any code. This also lets modpost.c use the same definition. Previously modpost relied on a hardcoded list of architectures in mk_elfconfig.c. A build test for blackfin, one of the two MODULE_SYMBOL_PREFIX archs, showed the generated code was unchanged. vmlinux was identical save for build ids, and an apparently randomized suffix on a single "__key" symbol in the kallsyms data).

* / microblaze: ftrace: Add dynamic trace supportMichal Simek2009-12-14
|/ | | | | | | | | | | | | | | | | | | | | | With dynamic function tracer, by default, _mcount is defined as an "empty" function, it returns directly without any more action. When enabling it in user-space, it will jump to a real tracing function(ftrace_caller), and do the real job for us. Differ from the static function tracer, dynamic function tracer provides two functions ftrace_make_call()/ftrace_make_nop() to enable/disable the tracing of some indicated kernel functions(set_ftrace_filter). In the kernel version, there is only one "_mcount" string for every kernel function, so, we just need to match this one in mcount_regex of scripts/recordmcount.pl. For more information please look at code and Documentation/trace folder. Steven ACK that scripts/recordmcount.pl part.

* USB: handle bcd incrementation in usb modalias generationNathaniel McCallum2009-12-11
| | | | | | | | | | | This patch fixes a bug when incrementing/decrementing on a BCD formatted integer (i.e. 0x09++ should be 0x10 not 0x0A). It just adds a function for incrementing/decrementing BCD integers by converting to decimal, doing the increment/decrement and then converting back to BCD.

* USB: add hex/bcd detection to usb modalias generationNathaniel McCallum2009-12-11
| | | | | | | | | | | | | | | | | | | | | | | | | The current code to generate usb modaliases from usb_device_id assumes that the device's bcdDevice descriptor will actually be in BCD format. While this should be a sane assumption, some devices don't follow spec and just use plain old hex. This causes drivers for these devices to generate invalid modalias lines which will never actually match for the hardware. The following patch adds hex support for bcdDevice in file2alias.c by detecting when a driver uses a hex formatted bcdDevice_(lo|hi) and adjusts the output to hex format accordingly. Drivers for devices which have bcdDevice conforming to BCD will have no change in modalias output. Drivers for devices which don't conform (i.e. ibmcam) should now generate valid modaliases.

Thus, docbook style comments that used to live with 'TRACE_EVENT()' are now moved to 'DEFINE_EVENT()'. Thus, we need to make the docbook system understand the new 'DEFINE_EVENT()' macro. In addition I've tried to futureproof the patch, by also adding support for 'DEFINE_SINGLE_EVENT()', since there has been discussion about renaming: TRACE_EVENT() -> DEFINE_SINGLE_EVENT().

The current code in recordmcount.pl will print a warning in this case. Unfortunately, there exists lots of files that may have this issue with older objcopys and this will cause a warning for every file compiled with this issue. This patch solves this overwhelming output by creating a .tmp_quiet_recordmcount file on the first instance the warning is encountered. The warning will not print if this file exists. The temp file is deleted at the beginning of the compile to ensure that the warning will happen once again on new compiles (because the issue is still present).
