When I use markup_oops.pl parse a x8664 oops, I got:
objdump: --start-address: bad number: NaN
No matching code found
This is because:
main::(./m.pl:228): open(FILE, "objdump -dS --adjust-vma=$vmaoffset --start-address=$decodestart --stop-address=$decodestop $filename |") || die "Cannot start objdump";
DB p $decodestart
NaNThis NaN is from:
main::(./m.pl:176): my $decodestart = Math::BigInt->from_hex("0x$target") - Math::BigInt->from_hex("0x$func_offset");
DB p $func_offset
0x175There is already a "0x" in $func_offset, another 0x makes it a NaN.
The $func_offset is from line:
if ($line =~ /RIP: 0010:\[\\] \[\\] ([a-zA-Z0-9\_]+)\+(0x[0-9a-f]+)\/0x[a-f0-9]/) {
$function = $1;
$func_offset = $2;
}I make a patch to change "(0x[0-9a-f]+)\/0x[a-f0-9]/)" to "0x([0-9a-f]+)\/0x[a-f0-9]/)".

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

When I try to use markup_oops.pl in x86, I always get:
cat 1 | perl markup_oops.pl ./vmlinux
objdump: --start-address: bad number: NaN
No matching code foundThis is because in line:
if ($line =~ /EIP is at ([a-zA-Z0-9\_]+)\+0x([0-9a-f]+)\/[a-f0-9]/) {
$function = $1;
$func_offset = $2;
}$func_offset will get a number like "0x2"
But in follow code:
my $decodestart = Math::BigInt->from_hex("0x$target") -
Math::BigInt->from_hex("0x$func_offset");It add other ox to ox2. Then this value will be set to NaN.
So I made a small patch to fix it.

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.Reported-by: Sebastian Dalfuß

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 0.48sSo 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]

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 -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
10c: R_MIPS_26 _mcount
10c: R_MIPS_NONE *ABS*
10c: R_MIPS_NONE *ABS*
110: 00020021 nopFor 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 v1In 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,v1,0If 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_callerIf 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, atBy 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!Signed-off-by: Wu Zhangjin

Despite being unused these should also get a CRC calculated.
Primarily I view this as a consistency thing. But I also think this is

avoided, and hence we should have the goal to eliminate this so that
failure to calculate a proper CRC for a symbol causes the build to fail).Signed-off-by: Jan Beulich

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.Signed-off-by: Jonathan Nieder

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"'.Suggested-by: Ryan Anderson

Use the --owner= and --group= options to make sure the entries in
the built tar file are owned by root. Without this change, a
careless sysadmin using the tar-pkg target can easily end up
installing a kernel that is writable by the unprivileged user
account used to build the kernel.Test that these options are understood before using them so that
non-GNU versions of tar can still be used if the operator is
appropriately cautious.Signed-off-by: Jonathan Nieder

As has been discussed previously (and Sam has been CC'ed), the fix
is still incorrect. It replaces "echo -ne" with "/bin/echo -ne",
but neither of the two are guaranteed to support the necessary
arguments and necessary (hexadecimal) escape sequences. What should
be used here is printf(1). The trivial patch below (on top of these
kbuild changes) fixes this issue.Signed-Off-By: Michael Tokarev

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.Signed-off-by: Nathaniel McCallum

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.EXAMPLE OUTPUT (ibmcam; space added to highlight change)
