All arch maintainers: 'make headers_check' fails on most architectures.

All arch maintainers: 'make headers_check' fails on most architectures.

[David Woodhouse]

Basically all but PowerPC and i386 have problems; and the latter works
only if you apply the patches I sent to Linus a few days ago.

This is just a basic check that the headers which _are_ exported don't
try to include other headers which aren't. This can happen either
because the former should not, or the latter _should_ be exported.
Mostly, however, the solution is just to make sure the latter is
included only within #ifdef __KERNEL__, because it's only needed within
that ifdef anyway.

Admittedly, much of the time this is only seen in files like asm/page.h
or asm/elf.h which we really don't expect anyone in userspace to be
using anyway -- but it would be good to fix them anyway.

Omitting the headers for which I've already sent patches to Linus, these
are the remaining problems found by running the scripts/hdrcheck.sh over
the exported kernel headers (automatically exported from Linus' current
tree, and available from
git://git.kernel.org/pub/scm/linux/kernel/git/dwmw2/kernel-headers.git )

[PATCH] [1/5] Fix 'make headers_check' on biarch architectures for 2.6.18

[David Woodhouse]

We generate an <asm/foo.h> which includes either <asm-$ARCH/foo.h> or
<asm-$ALTARCH/foo.h> as appropriate. But we were doing this dependent on
whether the file in question existed in the _unexported_ tree, not the
exported tree. So if a file was exported to userspace in one asm-
directory but not the other, the generated file in asm/ was incorrect.

This only changed the failure mode if it _was_ included from a nice
#error to a less explicable #include failure -- but it also gave false
errors in 'make headers_check' output. Fix it by looking in the right
place instead.

Move things around slightly so the right things end up within

Again, move stuff which shouldn't be visible inside (mostly already
existing) #ifdef __KERNEL__.

This fixes a bunch of mislabelled and unlabelled #endifs in unistd.h and
also cleans that up to conform with what's visible on other
architectures, since the minimal fix for the error reported about would
have involved a more intrusive patch, renesting other ifdefs.

As of today, a number of other architectures are fixed and we're left
with a few stragglers whose headers may not be clean in the
linux-kernel-headers tarball I intend to make based on the 2.6.18
release.

These have been fixed in patches which the architecture maintainer has
already sent to Linus:

asm-mips/posix_types.h requires asm/sgidefs.h, which does not exist in exported headers
asm-mips/ptrace.h requires asm/isadep.h, which does not exist in exported headers
asm-mips/sigcontext.h requires asm/sgidefs.h, which does not exist in exported headers
asm-mips/statfs.h requires asm/sgidefs.h, which does not exist in exported headers
asm-mips/stat.h requires asm/sgidefs.h, which does not exist in exported headers
asm-mips/unistd.h requires asm/sgidefs.h, which does not exist in exported headers
asm-mips/user.h requires asm/reg.h, which does not exist in exported headers

asm-parisc/page.h requires asm-generic/memory_model.h, which does not exist in exported headers

asm-frv/page.h requires asm-generic/memory_model.h, which does not exist in exported headers
asm-frv/ptrace.h requires asm/registers.h, which does not exist in exported headers

asm-frv/termios.h requires asm-generic/termios.h, which does not exist in exported headers
asm-frv/user.h requires asm/registers.h, which does not exist in exported headers


These have patches which have been sent to the arch maintainer but which
I believe have not yet been forwarded to Linus:

asm-arm/elf.h requires asm/procinfo.h, which does not exist in exported headers
asm-arm/page.h requires asm-generic/page.h, which does not exist in exported headers

It may be that UM and ARM26 don't need to be exporting headers, because
they can use headers from the host architecture and from ARM32,
respectively. If that's the case, we should just remove the Kbuild files
from those architectures' include directories.

Fixed.

This is going to need a little bit more work, but I've just bumped the
mask up for now. I just took care of the same issue on sh, so I'll carry
over the same fix for that later. SHMLBA at 0x4000 is "good enough" for
these caches for the time being, and fixes this issue.

According to
http://git.kernel.org/git/?p=linux/kernel/git/dwmw2/kernel-headers.git;a=blob;h=2ff7b41d3f154ef8c44fce542929a6ac02bd6c67;hb=2c461ab5bc8d3334d4dc97412c974bf09412fccd;f=asm-sh/shmparam.h
you don't define SHMLBA in the exported headers at all for SH[34] -- the
equivalent would be just putting #ifdef __KERNEL__ around what you
currently have in include/asm-sh64/shmparam.h (before your patch).

That's probably not such an unreasonable response. If you're going to
make it depend on the CPU cache, then libc is going to have to either
work it out for itself or query the kernel somehow. Or just use the
maximum of all possible values.

I'm not averse to removing <asm/shmparam.h> from view on _all_
architectures. The less we have to export, the better :)

A bunch of architectures define it as PAGE_SIZE anyway, which is broken
when PAGE_SIZE gets killed off -- which we're doing either because it's
dynamic on the arch in question or just because we're killing it on a
bunch of architectures so we should kill it on all for consistency.
Userspace needs to learn to use getpagesize() or sysconf(_SC_PAGE_SIZE).

Hm, is there a sysconf(_SC_SHMLBA) ?

I opted for the latter. The problem was that we can have varying
configurations where the aliases need to be handled differently (or not at
all), and rather than having shmparam.h turn in to ifdef hell, I opted for
run-time probing and setting up an shm_align_mask (as MIPS also does), and
then wrapping arch_get_unmapped_area() around it.

uClibc does that now, so it's not an issue there. As an alternative solution,
I was playing with handing the cache desc through the ELF auxvt and doing
similar run-time setup for the mask there, since most architectures with an
aliasing dcache will have special hacks anyways.

It seems cleaner to simply use the "big enough to covering aliasing
constraints if they exist" case and let get_arch_unmapped_area() pack it a bit
tighter based off of run-time discovery in the cases where we really care
about it.

For what it's worth, I suspect these two will have to do something
similar, as the dcache way size specifics won't be visible to userspace
under conventional means. This leaves the auxvt (alpha sets precedent
for this), or setting a value big enough to handle the aliasing
constraints.

The other thing I forgot to mention is that PAGE_SIZE is really the
wrong thing here anyways. On the systems with an aliasing dcache, it's
the 4k pages that are generally the problem. On those platforms you can
still switch to larger page sizes and then not have to worry about it.

So something like:

> Hm, is there a sysconf(_SC_SHMLBA) ?

would be much more useful. This would stop userspace libc's from doing
things like #define SHMLBA (getpagesize() * 4)..

In the 4k PAGE_SIZE case you still need the dcache specifics to figure
out whether to bump up SHMLBA or not. So you either go with the safe
route of using a "big enough" size that covers the worst-case aliasing
scenario, or find a way to do it at run-time (ie, via the auxvt or
_SC_SHMLBA).

I have extended that script somewhat to check for more problems,
and fixed a number of problems in the process.

The bad news is that with this extended script, there will be even
more work for each architecture maintainer to make it check without
warnings.

[patch 1/8] extend make headers_check to detect more problems

[Arnd Bergmann]

[-- Attachment #1: headercheck-base.diff --]
[-- Type: text/plain, Size: 2088 bytes --]

In addition to the problem of including non-existant header
files, a number of other things can go wrong with header
files exported to user space. This adds checks for some
common problems:

- The header fails to include the files it needs, which
  results in build errors when a program tries to include
  it. Check this by doing a dummy compile.

- There is a declarations of a static variable or non-inline
  function in the header, which results in object code
  in every file including it. Check for symbols in the object
  with 'nm'.

- Part of the header is subject to conditional compilation
  based on CONFIG_*. Add a regex search for this.

I found many problems with this, which I then fixed for
powerpc, s390 and i386, in subsequent patches.

[patch 2/8] fix byteorder headers for make headers_check

[Arnd Bergmann]

[-- Attachment #1: check-byteorder.diff --]
[-- Type: text/plain, Size: 3354 bytes --]

This makes the header files for byteorder includeable
on 32 bit systems with gcc -ansi, where no 64 bit
integers are available.

[patch 3/8] hide kernel-only parts of some installed headers

[Arnd Bergmann]

[-- Attachment #1: checkheader-__KERNEL__.diff --]
[-- Type: text/plain, Size: 30629 bytes --]

These header files all need additional parts hidden
inside if #ifdef __KERNEL__ so they become usable in
user space.

The most common reason is that they refer to a CONFIG_*
symbol. Since the contents of the header inside of
that #ifdef were undefined to start with, these parts
can usually be left out of the installed portion.

[patch 4/8] fix exported flock64 constants

[Arnd Bergmann]

[-- Attachment #1: headercheck-fcntl.diff --]
[-- Type: text/plain, Size: 6321 bytes --]

The asm-generic/fcntl.h header relied on CONFIG_64BIT
to determine if it should define some of its contents.

This does not work in user space where no CONFIG_ symbols
are available, so introduce a new __ARCH_FLOCK64 symbol
that is set by asm/fcntl.h before including asm-generic/fcntl.h
when an architecture wants these.

[patch 6/8] annotate header files for make headers_check

[Arnd Bergmann]

[-- Attachment #1: headercheck-annotate.diff --]
[-- Type: text/plain, Size: 29949 bytes --]

These files can only be included from user space if some
other header has been included first, and they don't look
like they should include that header themselves.

This uses a special '@headercheck: ... @' tag in a comment,
which is then turned into a gcc command line option that
will include the dependencies first.

All netfilter headers need something like this as well,
but I decided to make them a separate patch, because there
are so many of them.

The purpose of @headercheck: should be documented sonewhere.
A simple way to do so would be to paste the content of the changelog that
describe it in the top of this file.

Can't we do this with a hdrchk$$$ filename to avoid using
random entropy for each compile?

Replace nm with {NM:-nm} to obtain correct NM when cross compiling.

Paste output of nm so one can see what is defined?

I'd like to move to a scheme where we do headers_install and
headers_check _without_ starting with a rm -rf
$(HDR_INSTALL_PATH)/include.

We could probably do it by adding a rule along the lines of
$(filter-out $(unifdef-y) $(header-y),$(wildcard $(INSTALL_HDR_PATH)/$(dst)/*.h):
	rm $@
... i.e. remove every .h file from the destination directory except the
ones we just created. 

Then we can make $(INSTALL_HDR_PATH)/$(dst)/%.h depend on
$(srctree)/$(src)/%.h so that it doesn't get re-exported unless it's
changed. And we can keep a stamp file around (or the output of the test
compilation after Arnd's patch) which shows that the _check_ step has
been done too. Something like .checked.%.h

After we do that, a second invocation of 'make headers_check' should
have nothing to do, which will encourage people to keep using it.

ok. I've ended up writing more than that now, since the headers_install
target also wasn't documented well.

For now, I've hacked something up in the script below. I suppose
that can be improved with Dave's proposal by doing it from the
Makefile.

In addition to the problem of including non-existant header
files, a number of other things can go wrong with header
files exported to user space. This adds checks for some
common problems:

- The header fails to include the files it needs, which
  results in build errors when a program tries to include
  it. Check this by doing a dummy compile.

- There is a declarations of a static variable or non-inline
  function in the header, which results in object code
  in every file including it. Check for symbols in the object
  with 'nm'.

- Part of the header is subject to conditional compilation
  based on CONFIG_*. Add a regex search for this.

I found many problems with this, which I then fixed for
powerpc, s390 and i386, in subsequent patches.

+		Exporting data structures to user space
+
+
+===  Background
+
+Traditionally, headers in include/asm and include/linux symlinked to
+/usr/include [1]. This has always been a bad idea and stopped working
+well a few years ago. The next step was that distributions shipped
+their own copy of sometimes heavily modified headers to have
+something usable. Mariusz Mazur was maintaining pre-packaged
+linux-libc-headers [2] that were picked up by some distros but
+in the end that turned out too much work to keep up with.
+
+In 2.6.18, the current mechanism was merged, which uses Makefile
+in the include directory to install a minimal set of user space
+headers that can be used in /usr/include.
+
+
+===  Installing headers
+
+The 'make headers_install' command is used to install headers
+into the location specified with the 'INSTALL_HDR_PATH' environment
+variable. The default location for this is ${OBJDIR}/usr/include.
+
+Which headers get installed is specified in the 'Kbuild' file in
+the source directory containing each headers. The variables used
+in Kbuild to designate these files are:
+
+headers-y    Files that are installed verbatim from the source
+	     directory, as well subdirectories that also contain
+	     installable header files.
+objhdr-y     Files that are installed from the object directory,
+	     having been generated during the kernel build.
+unifdef-y    Files that have both parts for installations and
+	     parts that are private to the kernel. These files
+	     are run through the 'unifdef'(1) program that will
+	     strip all parts inside of '#ifdef __KERNEL__'.
+
+Apart from unifdef, all files are also run through a sed script
+that strips the usage of '#include <linux/compiler.h' [5].
+
+
+===  What should be in installed headers
+
+The contents of /usr/include/linux define the binary interface
+to the kernel. It should ideally only contain data structures
+and definitions of constants used on the kernel ABI. In particular,
+it is not a general helper library. While some applications
+are attempting to e.g. spinlocks or linked lists from the kernel
+in user space, such uses are usually subtly broken and should
+not be encouraged.
+
+The set of installed headers is supposed to be usable without
+dependencies on other files, so none of them can #include headers
+that are not also installed nor use types or macros defined
+elsewhere. Typically, this requires enclosing parts of the header
+inside of #ifdef __KERNEL__, or (preferred) splitting the header
+file into a file that can be included in user space and another
+one that contains the kernel-only parts and is not installed.
+
+
+===  Checking header files
+
+The 'make headers_check' target is used to perform a sanity
+check on the contents of the installed headers[6]. It checks for
+a number of common problems:
+
+- The header file includes another header that is not also
+  present in the set of installed headers.
+
+- The header fails to include the files it needs, which
+  results in build errors when a program tries to include
+  it. Check this by doing a dummy compile.
+
+- There is a declarations of a static variable or non-inline
+  function in the header, which results in object code
+  in every file including it. Check for symbols in the object
+  with 'nm'.
+
+- Part of the header is subject to conditional compilation
+  based on CONFIG_*. Add a regex search for this.
+
+Since the headers are different on each architectures, and
+at least the compile step of headers_check requires a compiler
+for the target architectures, only one architecture can be
+checked at a time.

 objhdr-y      Files that are generated automatically during the
               build process (i.e. include/linux/version.h) and
               are installed verbatim from the build directory.

Yup.

Is it OK that this happens when I do that:

	/home/jdike/linux/2.6/linux-2.6.17/scripts/Makefile.headersinst:42: /home/jdike/linux/2.6/linux-2.6.17/include/asm-um/Kbuild: No such file or directory

Er, yes. I don't think it makes any sense to export headers specifically
for UM. I wonder why my shadow git tree has them...

Well, my question was, is it OK for make to explode when headers_check is
done for UML, or should it do nothing silently?

headers_check should check whatever files are installed by headers_install.
I think the most sensible two choices there are:

1. install the headers for the actual underlying architecture (SUBARCH)
instead of the um headers.

2. if ARCH=um, don't provide headers_install or headers_check targets.

I don't think UML should be installing i386 headers.

Those are provided by the toplevel Makefile, so this would involve
wrapping an ifneq($ARCH, "um") around them, which doesn't seem too
palatable.

How does this look? Need to sort out dependencies for the .check.$FOO.h
files, but it does 'headers_install' relatively sanely with
dependencies, and also implements 'headers_install_all' with which we
can make a release tarball of linux-kernel-headers.
 
Oh, and I buggered the autogenerated files for biarch, but I'll fix that
later this evening.

It would be good to fix these problems, it's true -- but bear in mind
that none of these are actually fatal problems -- they're just caveats
of (ab)using kernel-private headers in userspace. 

On the other hand, it would be good to get people used to running
'make headers_check' whenever they make a change -- so introducing more
breakage right now may be counterproductive from that point of view.

So I think I'd prefer to leave this for now, or at least limit it to
'make CHECKMEHARDER=1 headers_check' so that we can wean people onto
using headers_check slowly and relatively painlessly.

Can you -include <linux/types.h> _every_ time, to reduce the number of
places you have to add '/* @headercheck: -include linux/types.h @ */' ?

yes, that sounds fair.

The problem with this are a few files which have code like

#ifndef __KERNEL__
#include <sys/types.h>
#include <stdint.h>
#endif

or similar. These break heavily if you include <linux/types.h> before the
the glibc provided headers, because linux/types.h provides some of the
types that are normally defined elsewhere and duplicate typedefs result
in compile errors.

To solve this, we would need to make all headers build fine with
gcc -D__STRICT_KERNEL_NAMES -include linux/types.h.
That is a valueable goal as well, since it avoids a number of problems,
but it is actually a larger change than this.

Now one option we could take would be to always pass -include linux/types.h
to gcc and put /* @headercheck: -D__STRICT_KERNEL_NAMES */ into the few
places that break otherwise.
