As the file is used by other platforms than Linux this change will
break them. Can you add a typedef similar to how __u8 and friends are
handled at the top of the file.

Yes, I added typedef size_t   __kernel_size_t; for other platforms.

This file isn't used by anyone else than Linus since years. All of the
typedefs can be nuked imo.

[PATCH 18/98] include/uapi/sound/emu10k1.h: added EMU10K1 version of DECLARE_BITMAP etc macros

[Mikko Rapeli]

Fixes userspace compilation error:

error: expected specifier-qualifier-list before ‘DECLARE_BITMAP’
  DECLARE_BITMAP(gpr_valid, 0x200); /* bitmask of valid initializers */

DECLARE_BITMAP etc macros are not meant for userspace headers and thus
added here as private copies for emu10k.h.

Fix was suggested by Arnd Bergmann <arnd@arndb.de> in message
<2168807.4Yxh5gl11Q@wuerfel> on lkml.

This is way too complicated just for a few expansion of the aligned
size arrays, IMO.  Rather simplify it like below with a comment:

/* the array must be aligned to unsigned long (i.e. 4 or 8 bytes) */
#define __EMU10K1_DECLARE_BITMAP(name) \
	unsigned long name[(bits) / sizeof(unsigned long)]
	
or expand as is at each place like:
	unsigned long gpr_valid[0x200 / sizeof(unsigned long)];


thanks,

What's the point of this one if you break this circular dependency in
patch 49? Are those in between related?

[PATCH 49/98] Break dependency loop between linux/if.h and linux/hdlc/ioctl.h

[Mikko Rapeli]

This isn't pretty but does the job. I assume including plain linux/hdlc/ioctl.h
without linux/if.h is much more rare than the other way round, and that
these header file names are part of API, and that creating a new header file
just for IFNAMSIZ isn't a good idea either.

This feels backwards to me. Wouldn't it be less funky to accept that
IFNAMSIZE isn't defined in if.h, but rather in hdlc/ioctl.h? If now
someone feels giddy and does

#include <linux/hdlc/ioctl.h>
#include <linux/if.h>

We have a new and unnecessary warning on our hands ;-)

Thanks,
Frans

That is much less funky, thanks! I'll squash these to commits into a one
which moves IFNAMSIZ to linux/hdlc/ioctl.h.

Here's the test which reproduces this https://lkml.org/lkml/2015/5/30/98

Should run on at least Debian based distributions and some cross compilers.
In the end the script generates a .c file which includes only this header file
and tries to compile it with a call like:

cc -Wall -c -nostdinc -I /usr/lib/gcc/i586-linux-gnu/4.9/include -I /usr/lib/gcc/i586-linux-gnu/4.9/include-fixed -I . -I ../headers_compile_test_include -I ../headers_compile_test_include/i586-linux-gnu ./linux/netfilter/ipset/ip_set_bitmap.c

It's even more or less required by the coding style. Chapter 5
(typedefs) says:

 (e) Types safe for use in userspace.

     In certain structures which are visible to userspace, we cannot
     require C99 types and cannot use the 'u32' form above. Thus, we
     use __u32 and similar types in all structures which are shared
     with userspace.

So this is probably an improvement in any case.

Thanks,
Frans

This is another thing which we need to address.  We should not be using
unsigned int/unsigned long/uintXX_t/etc in here, but the __uXX and __sXX
types.

The lesson learned from other DRM developers is that using these types
simplifies the API especially when it comes to the differences between
32-bit and 64-bit machines, and compat applications.

Note that drm/drm.h is all that should need to be included - drm/drm.h
takes care of including linux/types.h when building on Linux platforms.
(note: if your compiler doesn't set __linux__ then you're probably not
using the proper compiler...)

Using types that differs on 32-bit and 64-bit machines for a kernel 
interface is indeed a rather bad idea. This not only includes longs, but 
pointers as well.

But the int8_t, int16_t int32_t, int64_t and their unsigned counterparts 
are defined in stdint.h which is part of the ISO/IEC 9899:1999 standard, 
similar is true for size_t.

The __uXX, __sXX and _kernel_size_t types are linux specific as far as I 
know.

For best interoperability and standard conformance I think that 
definitions from the C standard we use should out-rule linux specific 
definitions.

Additional to that "linux/types.h" is not part of the uapi as far as I 
know, so including it in a header which is part of the uapi should be 
forbidden.

So this is a NAK from my side for the whole series, userspace programs 
should include <stdint.h> for the definition of the ISO/IEC 9899:1999 
standard types if necessary.

Regards,
Christian.

[cut standard stdint.h types argument which we've heard before]

You need to read Linus' rant on this subject:

 From: Linus Torvalds <torvalds-3NddpPZAyC0@public.gmane.org>
 Subject: Re: [RFC] Splitting kernel headers and deprecating __KERNEL__
 Date: Mon, 29 Nov 2004 01:30:46 GMT

 Ok, this discussion has gone on for too long anyway, but let's make it
 easier for everybody. The kernel uses u8/u16/u32 because:

         - the kernel should not depend on, or pollute user-space naming.
           YOU MUST NOT USE "uint32_t" when that may not be defined, and
           user-space rules for when it is defined are arcane and totally
           arbitrary.

         - since the kernel cannot use those types for anything that is
           visible to user space anyway, there has to be alternate names.
           The tradition is to prepend two underscores, so the kernel would
           have to use "__uint32_t" etc for its header files.

         - at that point, there's no longer any valid argument that it's a
           "standard type" (it ain't), and I personally find it a lot more
           readable to just use the types that the kernel has always used:
           __u8/__u16/__u32. For stuff that is only used for the kernel,
           the shorter "u8/u16/u32" versions may be used.

 In short: having the kernel use the same names as user space is ACTIVELY
 BAD, exactly because those names have standards-defined visibility, which
 means that the kernel _cannot_ use them in all places anyway. So don't
 even _try_.

Re: [PATCH 05/98] exynos_drm.h: use __u64 from linux/types.h

[Christian König]

Yeah, completely agree with Linus on the visibility problem and that's 
exactly the reason why we don't include <stdint.h> in the kernel header 
and expect userspace to define the ISO types somewhere.

But using the types from "include/linux/types.h" and especially 
including it into the uapi headers doesn't make the situation better, 
but rather worse.

With this step we not only make the headers depend on another header 
that isn't part of the uapi, but also pollute the user space namespace 
with __sXX and __uXX types which aren't defined anywhere else.

Regards,
Christian.

These __uXX and __sXX types are defined in
include/uapi/asm-generic/ll64.h and pulled in by
include/uapi/linux/types.h. Including linux/types.h is therefore
valid.

1) Header files are permitted to pollute userspace with __-defined stuff.

2) __[su]XX types are defined as part of the kernel's uapi.
   include/uapi/linux/types.h includes asm/types.h, which in userspace
   picks up include/uapi/asm-generic/types.h.  That picks up
   asm-generic/int-ll64.h, which defines these types.

Moreover, this is done throughout the kernel headers _already_ (as you
would expect for a policy set 10+ years ago).

Please, I'm not interested in this discussion, so please don't argue
with me - I may agree with your position, but what you think and what
I think are really not relevant here.  If you have a problem, take it
up with Linus - I made that clear in my email.

In this case I'm fine with the changes, but I'm still not sure if that's 
a good idea or not.

Sticking to ISO C still sounds better than doing something on our own. 
And it now looks a bit different than it was in 2004, stdint.h is widely 
adopted in userspace if I'm not completely mistaken.

Anyway you're perfectly right that Linus need to decide and I'm not in 
the mod to argue with him either (got way to much other things to do as 
well).

Christian.

Thanks, I'll fix this by including only drm/drm.h in exynos_drm.h,

As mentioned elsewhere one could avoid this, and just use drm.h to
manage the approapriate types (uint32_t vs __u32 and so on).

I fear that this one is a particular example of a nasty legacy from
the UMS days. The file is available/provided in very old mesa versions
and at the very same time mesa requires via_drm.h. So I would kindly
ask that you:

 - Grab the libdrm userspace package, and apply a similar change.
 - Rebuild/install the above.
 - Fetch mesa 7.11, and try building the via dri module. Ideally
things will continue to build, alternatively we might need to add
another/additional guard for this include.

Thanks
Emil

So the situation is "funnier" than expected:
 - There are at least two users of via_drm.h (mesa and xf86-video-via)
with each providing different via_drmclient.h.
 - Neither of the two projects includes the latter header, despite
that it uses the macros defined within.
 - via_drm.h is included via multiple headers, so adding extra ifdef
guards sounds like a bad idea.
 - While new version of the ddx can be released, a mesa one is
unlikely - 7.11.2 was released ~4 years ago.
 - Even if we cover the above two project, other projects (how many,
where are they hosted, etc.) may need the same treatment.

With the above said I'd suspect that we're safer leaving the include
as is ? Yes, it is busted if one tries to use the standalone header,
jet (most/all?) official users rely on that behaviour :-\

Cheers
Emil

We might want to follow the example of other drivers (i915) and move
it to drivers/gpu/drm/via_drv.h, There are two users of this struct
(via_drv.c and via_mm.c), and each one explicitly includes the header.
How does that sound ?

Same suggestion goes for the equivalent sis patch.

Cheers
Emil

Thanks, moved both of the file_private definitions to the driver headers.

[PATCH 36/98] include/uapi/asm-generic/shmbuf.h: include fixes

[Mikko Rapeli]

Include linux/types.h and asm/msgbuf.h and use __kernel_size_t instead
of size_t.

Fixes userspace compilation errors like:

error: field ‘shm_perm’ has incomplete type
struct ipc64_perm shm_perm; /* operation perms */
error: unknown type name ‘size_t’
error: unknown type name ‘__kernel_time_t’

[PATCH 95/98] HACK: fix include/uapi/xen/privcmd.h compilation in userspace

[Mikko Rapeli]

privcmd.h depends on xen/interface/xen.h which is now exported to userspace.
xen/interface/xen.h then depends on asm/xen/interface.h which is now
exported to userspace together with its dependencies asm/xen/interface_32.h,
asm/xen/interface_64.h and asm/pvclock-abi.h on x86 architecture.

Then all of these headers were fixed to use __u8 etc from linux/types.h
instead of custom types.

Then define uint64_t and uint32_t if needed.

After all these changes these header files now compile in userspace too
on x86.

HACK since I have no idea if this is correct way to fix this.

+ * @reqs is an array of mmu_update_t structures ((ptr, val) pairs).

+ *                    hypercall invocation. Can be DOMID_SELF.
+ * @foreigndom[31:16]: PFD, the expected owner of pagetable pages referenced
+ *                     in this hypercall invocation. The value of this field
+ *                     (x) encodes the PFD as follows:
+ *                     x == 0 => PFD == DOMID_SELF
+ *                     x != 0 => PFD == x - 1
+ *
+ * Sub-commands: ptr[1:0] specifies the appropriate MMU_* command.
+ * -------------
+ * ptr[1:0] == MMU_NORMAL_PT_UPDATE:
+ * Updates an entry in a page table belonging to PFD. If updating an L1 table,
+ * and the new table entry is valid/present, the mapped frame must belong to
+ * FD. If attempting to map an I/O page then the caller assumes the privilege
+ * of the FD.
+ * FD == DOMID_IO: Permit /only/ I/O mappings, at the priv level of the caller.
+ * FD == DOMID_XEN: Map restricted areas of Xen's heap space.
+ * ptr[:2]  -- Machine address of the page-table entry to modify.
+ * val      -- Value to write.
+ *
+ * There also certain implicit requirements when using this hypercall. The
+ * pages that make up a pagetable must be mapped read-only in the guest.
+ * This prevents uncontrolled guest updates to the pagetable. Xen strictly
+ * enforces this, and will disallow any pagetable update which will end up
+ * mapping pagetable page RW, and will disallow using any writable page as a
+ * pagetable. In practice it means that when constructing a page table for a
+ * process, thread, etc, we MUST be very dilligient in following these rules:
+ *  1). Start with top-level page (PGD or in Xen language: L4). Fill out
+ *      the entries.
+ *  2). Keep on going, filling out the upper (PUD or L3), and middle (PMD
+ *      or L2).
+ *  3). Start filling out the PTE table (L1) with the PTE entries. Once
+ *      done, make sure to set each of those entries to RO (so writeable bit
+ *      is unset). Once that has been completed, set the PMD (L2) for this
+ *      PTE table as RO.
+ *  4). When completed with all of the PMD (L2) entries, and all of them have
+ *      been set to RO, make sure to set RO the PUD (L3). Do the same
+ *      operation on PGD (L4) pagetable entries that have a PUD (L3) entry.
+ *  5). Now before you can use those pages (so setting the cr3), you MUST also
+ *      pin them so that the hypervisor can verify the entries. This is done
+ *      via the HYPERVISOR_mmuext_op(MMUEXT_PIN_L4_TABLE, guest physical frame
+ *      number of the PGD (L4)). And this point the HYPERVISOR_mmuext_op(
+ *      MMUEXT_NEW_BASEPTR, guest physical frame number of the PGD (L4)) can be
+ *      issued.
+ * For 32-bit guests, the L4 is not used (as there is less pagetables), so
+ * instead use L3.
+ * At this point the pagetables can be modified using the MMU_NORMAL_PT_UPDATE
+ * hypercall. Also if so desired the OS can also try to write to the PTE
+ * and be trapped by the hypervisor (as the PTE entry is RO).
+ *
+ * To deallocate the pages, the operations are the reverse of the steps
+ * mentioned above. The argument is MMUEXT_UNPIN_TABLE for all levels and the
+ * pagetable MUST not be in use (meaning that the cr3 is not set to it).
+ *
+ * ptr[1:0] == MMU_MACHPHYS_UPDATE:
+ * Updates an entry in the machine->pseudo-physical mapping table.
+ * ptr[:2]  -- Machine address within the frame whose mapping to modify.
+ *             The frame must belong to the FD, if one is specified.
+ * val      -- Value to write into the mapping entry.
+ *
+ * ptr[1:0] == MMU_PT_UPDATE_PRESERVE_AD:
+ * As MMU_NORMAL_PT_UPDATE above, but A/D bits currently in the PTE are ORed
+ * with those in @val.
+ *
+ * @val is usually the machine frame number along with some attributes.
+ * The attributes by default follow the architecture defined bits. Meaning that
+ * if this is a X86_64 machine and four page table layout is used, the layout
+ * of val is:
+ *  - 63 if set means No execute (NX)
+ *  - 46-13 the machine frame number
+ *  - 12 available for guest
+ *  - 11 available for guest
+ *  - 10 available for guest
+ *  - 9 available for guest
+ *  - 8 global
+ *  - 7 PAT (PSE is disabled, must use hypercall to make 4MB or 2MB pages)
+ *  - 6 dirty
+ *  - 5 accessed
+ *  - 4 page cached disabled
+ *  - 3 page write through
+ *  - 2 userspace accessible
+ *  - 1 writeable
+ *  - 0 present
+ *
+ *  The one bits that does not fit with the default layout is the PAGE_PSE
+ *  also called PAGE_PAT). The MMUEXT_[UN]MARK_SUPER arguments to the
+ *  HYPERVISOR_mmuext_op serve as mechanism to set a pagetable to be 4MB
+ *  (or 2MB) instead of using the PAGE_PSE bit.
+ *
+ *  The reason that the PAGE_PSE (bit 7) is not being utilized is due to Xen
+ *  using it as the Page Attribute Table (PAT) bit - for details on it please
+ *  refer to Intel SDM 10.12. The PAT allows to set the caching attributes of
+ *  pages instead of using MTRRs.
+ *
+ *  The PAT MSR is as follows (it is a 64-bit value, each entry is 8 bits):
+ *                    PAT4                 PAT0
+ *  +-----+-----+----+----+----+-----+----+----+
+ *  | UC  | UC- | WC | WB | UC | UC- | WC | WB |  <= Linux
+ *  +-----+-----+----+----+----+-----+----+----+
+ *  | UC  | UC- | WT | WB | UC | UC- | WT | WB |  <= BIOS (default when machine boots)
+ *  +-----+-----+----+----+----+-----+----+----+
+ *  | rsv | rsv | WP | WC | UC | UC- | WT | WB |  <= Xen
+ *  +-----+-----+----+----+----+-----+----+----+
+ *
+ *  The lookup of this index table translates to looking up
+ *  Bit 7, Bit 4, and Bit 3 of val entry:
+ *
+ *  PAT/PSE (bit 7) ... PCD (bit 4) .. PWT (bit 3).
+ *
+ *  If all bits are off, then we are using PAT0. If bit 3 turned on,
+ *  then we are using PAT1, if bit 3 and bit 4, then PAT2..
+ *
+ *  As you can see, the Linux PAT1 translates to PAT4 under Xen. Which means
+ *  that if a guest that follows Linux's PAT setup and would like to set Write
+ *  Combined on pages it MUST use PAT4 entry. Meaning that Bit 7 (PAGE_PAT) is
+ *  set. For example, under Linux it only uses PAT0, PAT1, and PAT2 for the
+ *  caching as:
+ *
+ *   WB = none (so PAT0)
+ *   WC = PWT (bit 3 on)
+ *   UC = PWT | PCD (bit 3 and 4 are on).
+ *
+ * To make it work with Xen, it needs to translate the WC bit as so:
+ *
+ *  PWT (so bit 3 on) --> PAT (so bit 7 is on) and clear bit 3
+ *
+ * And to translate back it would:
+ *
+ * PAT (bit 7 on) --> PWT (bit 3 on) and clear bit 7.

+	 *     becomes pending while the channel is masked then the 'edge' is lost
+	 *     (i.e., when the channel is unmasked, the guest must manually handle
+	 *     pending notifications as no upcall will be scheduled by Xen).
+	 *
+	 * To expedite scanning of pending notifications, any 0->1 pending
+	 * transition on an unmasked channel causes a corresponding bit in a
+	 * per-vcpu selector word to be set. Each bit in the selector covers a

- *                                         unsigned foreigndom)
- * @reqs is an array of mmu_update_t structures ((ptr, val) pairs).
- * @count is the length of the above array.
- * @pdone is an output parameter indicating number of completed operations
- * @foreigndom[15:0]: FD, the expected owner of data pages referenced in this
- *                    hypercall invocation. Can be DOMID_SELF.
- * @foreigndom[31:16]: PFD, the expected owner of pagetable pages referenced
- *                     in this hypercall invocation. The value of this field
- *                     (x) encodes the PFD as follows:
- *                     x == 0 => PFD == DOMID_SELF
- *                     x != 0 => PFD == x - 1
- *
- * Sub-commands: ptr[1:0] specifies the appropriate MMU_* command.
- * -------------
- * ptr[1:0] == MMU_NORMAL_PT_UPDATE:
- * Updates an entry in a page table belonging to PFD. If updating an L1 table,
- * and the new table entry is valid/present, the mapped frame must belong to
- * FD. If attempting to map an I/O page then the caller assumes the privilege
- * of the FD.
- * FD == DOMID_IO: Permit /only/ I/O mappings, at the priv level of the caller.
- * FD == DOMID_XEN: Map restricted areas of Xen's heap space.
- * ptr[:2]  -- Machine address of the page-table entry to modify.
- * val      -- Value to write.
- *
- * There also certain implicit requirements when using this hypercall. The
- * pages that make up a pagetable must be mapped read-only in the guest.
- * This prevents uncontrolled guest updates to the pagetable. Xen strictly
- * enforces this, and will disallow any pagetable update which will end up
- * mapping pagetable page RW, and will disallow using any writable page as a
- * pagetable. In practice it means that when constructing a page table for a
- * process, thread, etc, we MUST be very dilligient in following these rules:
- *  1). Start with top-level page (PGD or in Xen language: L4). Fill out
- *      the entries.
- *  2). Keep on going, filling out the upper (PUD or L3), and middle (PMD
- *      or L2).
- *  3). Start filling out the PTE table (L1) with the PTE entries. Once
- *      done, make sure to set each of those entries to RO (so writeable bit
- *      is unset). Once that has been completed, set the PMD (L2) for this
- *      PTE table as RO.
- *  4). When completed with all of the PMD (L2) entries, and all of them have
- *      been set to RO, make sure to set RO the PUD (L3). Do the same
- *      operation on PGD (L4) pagetable entries that have a PUD (L3) entry.
- *  5). Now before you can use those pages (so setting the cr3), you MUST also
- *      pin them so that the hypervisor can verify the entries. This is done
- *      via the HYPERVISOR_mmuext_op(MMUEXT_PIN_L4_TABLE, guest physical frame
- *      number of the PGD (L4)). And this point the HYPERVISOR_mmuext_op(
- *      MMUEXT_NEW_BASEPTR, guest physical frame number of the PGD (L4)) can be
- *      issued.
- * For 32-bit guests, the L4 is not used (as there is less pagetables), so
- * instead use L3.
- * At this point the pagetables can be modified using the MMU_NORMAL_PT_UPDATE
- * hypercall. Also if so desired the OS can also try to write to the PTE
- * and be trapped by the hypervisor (as the PTE entry is RO).
- *
- * To deallocate the pages, the operations are the reverse of the steps
- * mentioned above. The argument is MMUEXT_UNPIN_TABLE for all levels and the
- * pagetable MUST not be in use (meaning that the cr3 is not set to it).
- *
- * ptr[1:0] == MMU_MACHPHYS_UPDATE:
- * Updates an entry in the machine->pseudo-physical mapping table.
- * ptr[:2]  -- Machine address within the frame whose mapping to modify.
- *             The frame must belong to the FD, if one is specified.
- * val      -- Value to write into the mapping entry.
- *
- * ptr[1:0] == MMU_PT_UPDATE_PRESERVE_AD:
- * As MMU_NORMAL_PT_UPDATE above, but A/D bits currently in the PTE are ORed
- * with those in @val.
- *
- * @val is usually the machine frame number along with some attributes.
- * The attributes by default follow the architecture defined bits. Meaning that
- * if this is a X86_64 machine and four page table layout is used, the layout
- * of val is:
- *  - 63 if set means No execute (NX)
- *  - 46-13 the machine frame number
- *  - 12 available for guest
- *  - 11 available for guest
- *  - 10 available for guest
- *  - 9 available for guest
- *  - 8 global
- *  - 7 PAT (PSE is disabled, must use hypercall to make 4MB or 2MB pages)
- *  - 6 dirty
- *  - 5 accessed
- *  - 4 page cached disabled
- *  - 3 page write through
- *  - 2 userspace accessible
- *  - 1 writeable
- *  - 0 present
- *
- *  The one bits that does not fit with the default layout is the PAGE_PSE
- *  also called PAGE_PAT). The MMUEXT_[UN]MARK_SUPER arguments to the
- *  HYPERVISOR_mmuext_op serve as mechanism to set a pagetable to be 4MB
- *  (or 2MB) instead of using the PAGE_PSE bit.
- *
- *  The reason that the PAGE_PSE (bit 7) is not being utilized is due to Xen
- *  using it as the Page Attribute Table (PAT) bit - for details on it please
- *  refer to Intel SDM 10.12. The PAT allows to set the caching attributes of
- *  pages instead of using MTRRs.
- *
- *  The PAT MSR is as follows (it is a 64-bit value, each entry is 8 bits):
- *                    PAT4                 PAT0
- *  +-----+-----+----+----+----+-----+----+----+
- *  | UC  | UC- | WC | WB | UC | UC- | WC | WB |  <= Linux
- *  +-----+-----+----+----+----+-----+----+----+
- *  | UC  | UC- | WT | WB | UC | UC- | WT | WB |  <= BIOS (default when machine boots)
- *  +-----+-----+----+----+----+-----+----+----+
- *  | rsv | rsv | WP | WC | UC | UC- | WT | WB |  <= Xen
- *  +-----+-----+----+----+----+-----+----+----+
- *
- *  The lookup of this index table translates to looking up
- *  Bit 7, Bit 4, and Bit 3 of val entry:
- *
- *  PAT/PSE (bit 7) ... PCD (bit 4) .. PWT (bit 3).
- *
- *  If all bits are off, then we are using PAT0. If bit 3 turned on,
- *  then we are using PAT1, if bit 3 and bit 4, then PAT2..
- *
- *  As you can see, the Linux PAT1 translates to PAT4 under Xen. Which means
- *  that if a guest that follows Linux's PAT setup and would like to set Write
- *  Combined on pages it MUST use PAT4 entry. Meaning that Bit 7 (PAGE_PAT) is
- *  set. For example, under Linux it only uses PAT0, PAT1, and PAT2 for the
- *  caching as:
- *
- *   WB = none (so PAT0)
- *   WC = PWT (bit 3 on)
- *   UC = PWT | PCD (bit 3 and 4 are on).
- *
- * To make it work with Xen, it needs to translate the WC bit as so:
- *
- *  PWT (so bit 3 on) --> PAT (so bit 7 is on) and clear bit 3
- *
- * And to translate back it would:
- *
- * PAT (bit 7 on) --> PWT (bit 3 on) and clear bit 7.

Historical reasons expect xen/interface/xen.h to be a verbatim copy of
the master version kept in the Xen repository.

The only things privcmd.h need from interface/xen.h are domid_t
(uint16_t), and xen_pfn_t (unsigned long, or uint64_t in arm32 iirc),
while the majority of the rest absolutely shouldn't be in Linux’s uapi.

It would probably be best to provide just these two types and nuke the
"#include <xen/interface/xen.h>".  Any user of privcmd needs to include
the Xen interface themselves anyway, and will have a different copy
which includes the toolstack half of the interface (missing from the
kernel copy) which is the useful set of definitions for driving the
privcmd ioctl()s.

[PATCH 96/98] HACK include/uapi/linux/coda_psdev.h: fix compilation in userspace

[Mikko Rapeli]

Include linux/coda.h for caddr_t and use unsigned short type directly.
Userspace headers do not have list_head and wait_queue_head_t so just
ifdef them away which is a HACK. Any ideas how to fix this properly?

I grepped the Coda userspace sources and it doesn't look like this
particular struct is used there anyway, it is only used by the kernel
module to track which requests are waiting to be read by the Coda
userspace application and after that which requests are waiting for a
response.

I guess a proper fix would be to move this struct to a non-uapi header,
or maybe even to the (probably) only C file in the kernel where it is
used.

[PATCH 97/98] HACK include/uapi/linux/elfcore.h: use __kernel_pid_t and remove elf_greg_t stuff in userspace

[Mikko Rapeli]

__kernel_pid_t change feels like right one. Commenting out elf_greg_t
things in userspace does not but exporting x86/include/asm/elf.h and its
dependencies to userspace does not feel right either. Hence HACK.

Fixes userspace compilation errors like:

error: unknown type name ‘elf_greg_t’
 typedef elf_greg_t greg_t;
error: unknown type name ‘pid_t’
  pid_t pr_pid;

Ugh. This opens up a can of worms. And not just a single can. Every
architecture supported by Linux has one, for every supported binary
format.

So uapi has a number of headers for exporting process core dump
related structs and defines to userspace. Sadly elfcore.h does not compile in
userspace as is and practically depends on architecture specific
defines for the elf file format and all the way done to some memory
management details which are not part of uapi.

Since the headers are not exported to userspace, a grep with
elf_greg_t definition in my /usr/include shows that gcc has its own modified
version of these headers which have the details which gdb needs, in
sys/procfs.h, sys/user.h and friends. Also linux-tools has it's own modified
versions of these headers with comments like
"Make sure these layouts match the linux/elfcore.h native definitions."

Search on Debian source code tree shows that real users of linux/elfcore.h
don't really exist and everyone has had to create their own copies
with all relevant dependencies to make things work in user space.

On the long term would be nice if these header file worm cans were cleaned
up but for the short term I'd like to get elfcore.h compiling so that I can
continue fiddling with kernel header sanity tests and API and ABI
compatibility checks. For this reason I'd like to propose this dumb solution
for now which:

 * removes typedef elf_greg_t greg_t and friends from userspace headers
 * removes struct elf_prstatus from userspace headers

Comments?

[PATCH 98/98] HACK include/uapi/linux/errqueue.h: include time.h in userspace

[Mikko Rapeli]

linux/time.h conflicts with userspace header time.h. Try to be compatible
for kernel and userspace.

Hi,

Any comments about this change? I assume the <linux/time.h> and <time.h>
incompatibility in userspace is a known thing and the resulting definitions
are compatible.
