Those configs are not new:
$ cat .config
...
CONFIG_NAMESPACES=y
...
CONFIG_BLOCK=y
...
But are tagged as NEW:
$ yes "" | make config > myconf
$ cat myconf | grep '(NEW)'
Namespaces support (NAMESPACES) [Y/?] (NEW) y
...
Enable the block layer (BLOCK) [Y/?] (NEW) y
...
You can also notice this bug when using gconfig/xconfig.
It's because the SYMBOL_DEF_USER bit of an invisible symbol is cleared
when the config file is read:
int conf_read(const char *name)
{
...
for_all_symbols(i, sym) {
if (sym_has_value(sym) && !sym_is_choice_value(sym)) {
/* Reset values of generates values, so they'll appear
* as new, if they should become visible, but that
* doesn't quite work if the Kconfig and the saved
* configuration disagree.
*/
if (sym->visible == no && !conf_unsaved)
sym->flags &= ~SYMBOL_DEF_USER;
...
}
But a menu item which represents an invisible symbol is still
visible, if it's sub-menu is visible, so its SYMBOL_DEF_USER
bit should be set to indicate it's not NEW.

This patch has been around for a long time in Fedora and Red Hat Enterprise
Linux kernels and it may be useful for others. The nonint_oldconfig target
will fail and print the unset config options while loose_nonint_oldconfig will
simply let the config option unset. They're useful in distro kernel packages
where the config files are built using a combination of smaller config files.
Arjan van de Ven wrote the initial nonint_config and Roland McGrath added the
loose_nonint_oldconfig.

This changes the default of the option --git-all-signature-types to be
disabled by default.
The effect being, that only certain (currently Signed-Off-By:, Acked-by:
and Reviewed-By:) tags are used to get adresses of potential maintainers.
Motivated is this change by the desire to not 'spam' people unnecessary: A
Tested-By or a Reported-By is not ment as a hint that those people want
to/are able to review patches to the code in question.
In a quest to find resilient statistics for this i came up with this:
I produced a list of all the tag-signers not already covered with a
signed-off/acked/reviewed tag somewhere in the last year of git history.
Those were 650 addresses of "assumed non-developers".
And to check if those "assumed non-developers" are professional
testers/reporters worth cc'ing, i then counted their total appearences
in the git log:
469 were mentioned only once.
123 were mentioned twice.
38 three times
8 four times
5 six times
5 five times
1 eight times
1 fourteen times
I believe this supports my thesis, that the ''non-maintainer-tags'' are
not actively useful for patch-review. (except probably the guy mentioned
fourteen times...)
But of course one could also find arguments to poke holes in this
statistics, for example does this statistic not include code-locality: A
tested-by on a patch that touches some specific piece of code can be more
worth than a signed-off in another part of the tree.
But... let's play it safe and let's err on the "safe" side meaning to not
spam those people when in doubt. We already have the signed-off's and
Maintainers file. So this should be ok. And if need be, the maintainers
can always forward the patch.

When using --git to determine who to send a patch to, get_maintainers will
currently include all signatures. This can include signers that simply
report an issue or test a patch. Signers that use this tag are not
necessarily good candidates to review new patches.
This patch allows get_maintainers to optionally restrict output to only
signatures that use Signed-off-by:, Acked-by:, or Reviewed-by:.
Signed-off-by: is included because those are people who are responsible
for the code.
Acked-by: is questionable, but as signers that use this tag tend to be
active linux gatekeepers, false positives are tolerable.
Reviewed-by: is included because signers responsible for the code thought
that the review feedback for a changeset by that signer was valuable.
This patch has been modified from Florian's original submission to change
the supported signature types to the canonical forms and use slightly
different spacing. A couple of spacing issues were also corrected in the
original source. The command line argument was also renamed.

The patch below works fine (at least with Debian). It needs your first
patch that moves the definitions to mod_devicetable.h. Verified that
aliases for these modules are generated correctly:
drivers/media/radio/radio-sf16fmi.c
drivers/net/ne.c
drivers/net/3c515.c
drivers/net/smc-ultra.c
drivers/pcmcia/i82365.c
drivers/scsi/aha1542.c
drivers/scsi/aha152x.c
drivers/scsi/sym53c416.c
drivers/scsi/g_NCR5380.c
Tested with RTL8019AS (ne), AVA-1505AE (aha152x) and dtc436e (g_NCR5380)
cards - they now work automatically.
Generate pnp:d aliases for isapnp_device_tables. This allows udev to load
these modules automatically.

Minor perlcritic warning:
headerdep.pl: "return" statement with explicit "undef" at line 84, column 2. See page 199 of PBP. (Severity: 5)
The rationale according to PBP is that an explicit return of undef
(contrary to most people's expectations) doesn't
always evaluate as false. It has to with the fact that perl return value
depends on context the function is called. If function is used in
list context, the appropriate return value for false is an empty list;
whereas in scalar context the return value for false is undefined.
By just using a "return" both cases are handled.
In the context of a trivial script this doesn't matter. But one script
may be cut-paste into later code (most people like me only know 50%
of perl), that is why perlcritic always complains

Here is a small code snippet, which will be complained about by
checkpatch.pl:
#define __STRUCT_KFIFO_COMMON(recsize, ptrtype) \
union { \
struct { \
unsigned int in; \
unsigned int out; \
}; \
char rectype[recsize]; \
ptrtype *ptr; \
const ptrtype *ptr_const; \
};
This construct is legal and safe, so checkpatch.pl should accept this. It
should be also true for struct defined in a macro.
Add the `struct' and `union' keywords to the exceptions list of the
checkpatch.pl script, to prevent error message "Macros with multiple
statements should be enclosed in a do - while loop". Otherwise it is not
possible to build a struct or union with a macro.

Add an imperfect option to search a source file for email addresses.
New option: --file-emails or --fe
email addresses in files are freeform text and are nearly impossible to
parse. Still, might as well try to do a somewhat acceptable job of
finding them. This code should find all addresses that are in the form
addr@domain.tld
The code assumes that up to 3 alphabetic words along with dashes, commas,
and periods that preceed the email address are a name.
If 3 words are found for the name, and one of the first two words are a
single letter and period, or just a single letter then the 3 words are use
as name otherwise the last 2 words are used.
Some variants that are shown correctly:
John Smith <jksmith@domain.org>
Random J. Developer <rjd@tld.com>
Random J. Developer (rjd@tld.com)
J. Random Developer rjd@tld.com
Variants that are shown nominally correctly:
Written by First Last (funny-addr@somecompany.com)
is shown as:
First Last <funny-addr@somecompany.com>
Variants that are shown incorrectly:
Some Really Long Name <srln@foo.bar>
MontaVista Software, Inc. <source@mvista.com>
are returned as:
Long Name <srln@foo.bar>
"Software, Inc" <source@mvista.com>
--roles and --rolestats show "(in file)" for matches.
For instance:
Without -file-emails:
$ ./scripts/get_maintainer.pl -f -nogit -roles net/core/netpoll.c
David S. Miller <davem@davemloft.net> (maintainer:NETWORKING [GENERAL])

The problem is that $. keeps track of the current record number (which

not wrap at the end of file, and therefore contains the *total* number

Currently looking up a structure definition in TAGS / tags takes one to
one of multiple "static struct X" definitions in arch sources, which makes
it for many structs practically impossible to get to the required header.
This patch changes the order of sources being tagged to first scan
architecture includes, then the top-level include/ directory, and only
then the rest. It also takes into account, that many architectures have
more than one include directory, i.e., not only arch/$ARCH/include, but
also arch/$ARCH/mach-X/include etc.

Doing the following:
make LSMOD=file localmodconfig
Will make the streamline-config code use the given file instead of
lsmod. If the file is an executable, it will execute it, otherwise
it will read it as text.
make LSMOD=/my/local/path/lsmod localmodconfig
The above will execute the lsmod in /my/local/path instead of the
lsmods that may be located elsewhere.
make LSMOD=embedded_board_lsmod localmodconfig
The above will read the "embedded_board_lsmod" as a text file. This
is useful if you are doing a cross compile and need to run the
config against modules that exist on an embedded device.
Note, if the LSMOD= file does is not a path, it will add the
path to the object directory. That is, the above example will look
for "embedded_board_lsmod" in the directory that the binary will
be built in (the O=dir directory).

Just a small change to a couple of scripts to go from

to
#!/usr/bin/python
This shouldn't effect anyone, unless they don't install python there.
In preparation for python3, Fedora is doing a big push to change the scripts
to use the system python. This allows developers to put the python3 in
their path without fear of breaking existing scripts.
Now I am pretty sure anyone using python3 for testing purposes will probably
not run any of the scripts I changed, but Fedora has this automated tool
that checks for this stuff so I thought I would try to push it upstream.

While looking for something else I noticed that the symbol
hash function used by kconfig is quite poor. It doesn't
use any of the standard hash techniques but simply
adds up the string and then uses power of two masking,
which is both known to perform poorly.
The current x86 kconfig has over 7000 symbols.
When I instrumented it showed that the minimum hash chain
length was 16 and a significant number of them was over
30.
It didn't help that the hash table size was only 256 buckets.
This patch increases the hash table size to a larger prime
and switches to a FNV32 hash. I played around with a couple of hash
functions, but that one seemed to perform best with reasonable
hash table sizes.
Increasing the hash table size even further didn't
seem like a good idea, because there are a couple of global
walks which walk the complete hash table.
I also moved the unnamed bucket to 0. It's still the longest
of all the buckets (44 entries), but hopefully it's not
often hit except for the global walk which doesn't care.
The result is a much nicer distribution:
(first column bucket length, second number of buckets with that length)
1: 3505
2: 1236
3: 294
4: 52
5: 3
47: 1 <--- this is the unnamed symbols bucket
There are still some 5+ buckets, but increasing the hash table
even more would be likely not worth it.
This also cleans up the code slightly by removing hard coded

This patch was inspired by the kernel projects page, where an ncurses
replacement for menuconfig was mentioned (by Sam Ravnborg).
Building on menuconfig, this patch implements a more modern look
interface using ncurses and ncurses' satellite libraries (menu, panel,
form). The implementation does not depend on lxdialog, which is
currently distributed with the kernel.

Help text for certain config options is very extensive (the text
includes the names of all other options the option in question depends
on). Long lines are not wrapped, making it impossible to see the list
without scrolling horizontally.
This patch adds some logic which wraps help screen lines at word
boundaries to prevent truncating.
Tested by running
ARCH=powerpc make menuconfig O=/tmp/build
which shows that the long lines are now wrapped, and
ARCH=powerpc make xconfig O=/tmp/build
to demonstrate that it still compiles and operates as expected.

This patch adds support for decoding ARM oopses to scripts/decodecode.
The following things are handled:
- ARCH and CROSS_COMPILE environment variables are respected.
- The Code: in x86 oopses is in bytes, while it is in either words (4
bytes) or halfwords for ARM.
- Some versions of ARM objdump refuse to disassemble instructions
generated by literal constants (".word 0x..."). The workaround is to
strip the object file first.
- The faulting instruction is marked (liked so) in ARM, but <like so>
in x86.
- ARM mnemonics may include characters such as [] which need to be
escaped before being passed to sed for the "<- trapping instruction"
substitution.

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';

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.

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

Fixed non-conflicting clean merge of modpost.c as per comments from
Stephen Rothwell (modpost.c had grown an include of linux/autoconf.h
that needed to be changed to generated/autoconf.h)
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 <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!

The next commit will require the use of MODULE_SYMBOL_PREFIX in
.tmp_exports-asm.S. 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).

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.

To make it easier for module-init-tools and scripts like mkinitrd to
distinguish builtin and missing modules, install a modules.builtin file
listing all builtin modules. This is done by generating an additional
config file (tristate.conf) with tristate options set to uppercase 'Y'
or 'M'. If we source that config file, the builtin modules appear in
obj-Y.

Despite being unused these should also get a CRC calculated.
Primarily I view this as a consistency thing. But I also think this is
one of the reasons why __crc_* need to be weak (which I think should be
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).

Fix handling of input files (e.g. with no newline at EOF) that could
make unifdef get into an unexpected state and call abort().
The new -B option compresses blank lines around a deleted section
so that blank lines around "paragraphs" of code don't get doubled.
The evaluator can now handle macros with arguments, and unbracketed
arguments to the "defined" operator.
Add myself to MAINTAINERS for unifdef.

Cscope doesn't hadle relative paths when cscope.out is not in $PWD. Use
absolute paths when generating cscope.files, which seems to be the
recommended way to generate cscope.out, anyway (at least according to
cscope.sf.net). The speed and size differences are minimal, the only
drawback is that the database needs to be regenerated if the source
directory is moved.

The toplevel Makefile creates the directory if it runs silentoldconfig
automatically, but if run manually, it fails:
$ make mrproper
$ make defconfig && make silentoldconfig
*** Default configuration is based on 'x86_64_defconfig'
#
# configuration written to .config

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.

Let the deb-pkg target acquire (fake) root privileges before
running commands that need them. 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"'.

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.

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.

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.
