I've spent the last week or so getting ftrace et al. working
again on sparc64. The NMI scheme I use there was causing all
sorts of issues, but luckily the final fix was very simple.
While I was here debugging this stuff I added function graph
tracer support, as well as support for kmemleak. Kmemleak
even found a bug :-)
All combinations of features seems to work (perf top with tracers,
lockdep, and kmemleak all enabled for example) and wow is this stuff
super-useful :-)
I merged in your tree to resolve a conflict in lib/Kconfig.debug
since Microblaze added kmemleak support recently too.
Please pull, thanks a lot!

Couple sparc fixes that have piled up over the past few week:
1) L1_CACHE_ALIGN macro unnecessary, from FUJITA Tomonori
2) _FP_FROM_INT() math-emu off-by-one bug that hits sparc and
other math-emu using platforms. From Mikael Pettersson.
3) Add missing DWARF register lookup to perf.
4) When console= is explicitly specified for a serial console,
don't try to override with firmware provided settings.
5) Use after free in sunsu driver.
6) maybe_change_configuration() perf event code uses wrong %pcr
setting, notices by Peter Z.
7) Fix build failure in some configs, from Dongdong Deng.
Please pull, thanks a lot!

Just some misc sparc64 bits:
1) Add missing ID to sparc64 parport support.
2) Sync sparc64's perf_arch_get_caller_regs() with recent changes.
3) Toss user-copy check code, it never worked properly on sparc for
whatever reason and just adds warning noise to the logs.

Just some misc sparc64 bits:
1) Add missing ID to sparc64 parport support.
2) Sync sparc64's perf_arch_get_caller_regs() with recent changes.
3) Toss user-copy check code, it never worked properly on sparc for
whatever reason and just adds warning noise to the logs.
Please pull, thanks a lot!

Your commit message is missing the C rules for hex constants. It says
"hex constants are unsigned unless explicitly casted or negated."
and that's not true.
The rule is that hex constants are signed _except_ if they don't fit
in a signed.
So with a 32-bit 'int', 0x123 is signed, but 0x80000000 is unsigned.
So the reason (-0x00010000) is signed is _not_ because of the
negation, but simply because 0x00010000 fits in a signed int. So for
example, the constant (-0xf0000000) is still unsigned, despite the
negation.
So to make something signed, you need to either cast it, make sure it
fits in a signed int, use the 'l' postfix (which also makes it long,
of course), or use a decimal representation. So
#define X 4294901760
is a _signed_ constant with same value as 0xffff0000 (but it's "signed
long", because the rules for decimal numbers and hex numbers are
different: a decimal number is always signed and because it doesn't
fit in 'int' it will extend to 'long'. A hex number is first done as
unsigned, and only extended to long if it doesn't fit in that.
To make things _really_ confused, sometimes the types actually depend
on whether you're compiling with the c90 standards. A decimal constant
is _always_ signed in traditional C - it goes from 'int' to 'long',
and stays 'long' even if it doesn't fit (ie with a 32-bit long,
2147483648 is of type 'long' even though it doesn't fit in 'long' and
is negative). But in c90, it does from 'int' to 'long' to 'unsigned
long'.
Or maybe it was the other way around. I forget.
Confused yet?
The basic rule becomes: never _ever_ overflow 'int' in a constant,
without specifying the exact type you want. That way you avoid all the
subtle cases.

Oh,
I noticed another thing:
In commit 86fa04b8742ac681d470786f55e2403ada0075b2 you fix the return
type, but you still have the wrong _argument_ type:
extern void atomic64_add(int, atomic64_t *);
extern void atomic64_sub(int, atomic64_t *);
extern long atomic64_add_ret(int, atomic64_t *);
extern long atomic64_sub_ret(int, atomic64_t *);
note how if somebody does
atomic64_add(0x100000000ull, &x)
sparc64 will get it wrong, because it will only take the low 32 bits
of the first argument, and add zero to the 64-bit counter.
Which is definitely not what the code intended, I think.
I merged your pull request, but you've got some fixing up to do,
methinks. I also really think you need to make your rwsem's use 64-bit
values on sparc64, because otherwise you can overflow the mmap_sem by
having more than 65536 threads doing page-faults (on 32-bit, having
more than 2**16 threads in one process is unlikely to work for other
reasons, like just pure stack usage, so we don't really care about the
32-bit case)

32K threads :-) you guys are nuts !
Here's an untested patch for the folks on linuxppc-dev to look at, I'll
review my own stuff & test tomorrow.
Cheers,

powerpc: Make rwsem use "long" types on 64-bit platforms
This should avoid overflow of the mmap_sem when playing with insane
number of threads.

32K threads :-) you guys are nuts !
Here's an untested patch for the folks on linuxppc-dev to look at, I'll
review my own stuff & test tomorrow.
Cheers,
Ben.
powerpc: Make rwsem use "long" types on 64-bit platforms
This should avoid overflow of the mmap_sem when playing with insane
number of threads.

Allright, gcc's being a pain, and atomics are a struct so we can't that
easily assign.
I tried various tricks but so far they didn't work. I'll have another
look tomorrow, but I may end up having to keep all the crap typecasts.
Cheers,
Ben.

The casts are pretty much unavoidable.
Here's what I'm going to end up using on sparc64:
--------------------
sparc64: Make rwsems 64-bit.
Basically tip-off the powerpc code, use a 64-bit type and atomic64_t
interfaces for the implementation.
This gets us off of the by-hand asm code I wrote, which frankly I
think probably ruins I-cache hit rates.
The idea was the keep the call chains less deep, but anything taking
the rw-semaphores probably is also calling other stuff and therefore
already has allocated a stack-frame. So no real stack frame savings
ever.
Ben H. has posted patches to make powerpc use 64-bit too and with some
abstractions we can probably use a shared header file somewhere.

The casts are pretty much unavoidable.
Here's what I'm going to end up using on sparc64:
--------------------
sparc64: Make rwsems 64-bit.
Basically tip-off the powerpc code, use a 64-bit type and atomic64_t
interfaces for the implementation.
This gets us off of the by-hand asm code I wrote, which frankly I
think probably ruins I-cache hit rates.
The idea was the keep the call chains less deep, but anything taking
the rw-semaphores probably is also calling other stuff and therefore
already has allocated a stack-frame. So no real stack frame savings
ever.
Ben H. has posted patches to make powerpc use 64-bit too and with some
abstractions we can probably use a shared header file somewhere.

Similar here, but using atomic_long_t instead so it works for 32-bit too
for me. I suppose we could make that part common indeed.
What about asm-generic/rwsem-atomic.h or rwsem-cmpxchg.h ?
Below is my current patch, seems to boot fine here so far.
Cheers,
Ben
Subject: [PATCH] powerpc: Make rwsem use "long" type
This makes the 64-bit kernel use 64-bit signed integers for the counter
(effectively supporting 32-bit of active count in the semaphore), thus
avoiding things like overflow of the mmap_sem if you use a really crazy
number of threads

Similar here, but using atomic_long_t instead so it works for 32-bit too
for me. I suppose we could make that part common indeed.
What about asm-generic/rwsem-atomic.h or rwsem-cmpxchg.h ?
Below is my current patch, seems to boot fine here so far.
Cheers,

Subject: [PATCH] powerpc: Make rwsem use "long" type
This makes the 64-bit kernel use 64-bit signed integers for the counter
(effectively supporting 32-bit of active count in the semaphore), thus
avoiding things like overflow of the mmap_sem if you use a really crazy
number of threads

Other architectures who support cmpxchg and atomic_long can
use that directly.

This makes the 64-bit kernel use 64-bit signed integers for the counter
(effectively supporting 32-bit of active count in the semaphore), thus
avoiding things like overflow of the mmap_sem if you use a really crazy
number of threads

The implementation looks good for asm-generic, but there is now an asymmetry
between the spinlock and the atomic_long_t based version.
Maybe we can make them both do the same thing, either of
1. create include/linux/rwsem-cmpxchg.h and add an
#elif defined(CONFIG_RWSEM_GENERIC_ATOMIC) to include/linux/rwsem.h
2. move include/linux/rwsem-spinlock.h to include/asm-generic/ and
include that from all architectures that want the spinlock based version.
Further comments:
* Alpha has an optimization for the uniprocessor case, where the atomic
instructions get turned into nonatomic additions. The spinlock based
version uses no locks on UP but disables interrupts for reasons I don't
understand (nothing running at interrupt time should try to access an rwsem).
Should the generic version do the same as Alpha?
* Is there any architecture that would still benefit from having a separate
rwsem implementation? AFAICT all the remaining ones are just variations of
the same concept of using cmpxchg (or xadd in case of x86), which is what
atomics typically end up doing anyway.

I've seen drivers in the past do trylocks at interrupt time ... tho I
agree it sucks.

It depends how sensitive rwsems are.
The "generic" variant based on atomic's and cmpxchg on powerpc is
sub-optimal in the sense that it has stronger memory barriers that would
be necessary (atomic_inc_return for example has both acquire and
release).
But that vs. one more pile of inline asm, we decided it wasn't hot
enough a spot for us to care back then.
Cheers,
Ben.

Recently there was a thread where this was declared absolutely illegal.
Maybe it was allowed, or sort-of worked before, and that's why it's
accounted for with IRQ disables in some implementations. I don't
know.

Ok, I'm happy to say it's a big no-no then.
Arnd, do you want to take over the moving to asm-generic and take care
of the spinlock case as well ? I can send Linus the first patch that
changes powerpc to use atomic_long now along with a few other things I
have pending, then you can pickup from there. Or do you want me to
continue pushing my patch as-is and we can look at cleaning up the
spinlock case separately ?
Cheers,
Ben.

Actually, it's not that complicated:
1) base and suffices choose the possible types.
2) order of types is always the same: int -> unsigned -> long -> unsigned
long -> long long -> unsigned long long
3) we always choose the first type the value would fit into
4) L in suffix = "at least long"
5) LL in suffix = "at least long long"
6) U in suffix = "unsigned"
7) without U in suffix, base 10 = "signed"
That's it. C90 differs from C99 only in one thing - long long (and LL) isn't
there. The subtle mess Linus has mentioned is C90 gccism: gcc has allowed
unsigned long for decimal constants, as the last resort. I.e. if you had
a plain decimal constant that wouldn't fit into long but would fit into
unsigned long, gcc generated a warning and treated it as unsigned long.
C90 would reject the damn thing. _Bad_ extension, since in C99 the same
constant would be a legitimate signed long long.
But yes, "use the suffix when unsure" is a damn good idea, _especially_ since
the sizeof(long) actually varies between the targets we care about.

Actually, it's not that complicated:
1) base and suffices choose the possible types.
2) order of types is always the same: int -> unsigned -> long -> unsigned
long -> long long -> unsigned long long
3) we always choose the first type the value would fit into
4) L in suffix == "at least long"
5) LL in suffix == "at least long long"
6) U in suffix == "unsigned"
7) without U in suffix, base 10 == "signed"
That's it. C90 differs from C99 only in one thing - long long (and LL) isn't
there. The subtle mess Linus has mentioned is C90 gccism: gcc has allowed
unsigned long for decimal constants, as the last resort. I.e. if you had
a plain decimal constant that wouldn't fit into long but would fit into
unsigned long, gcc generated a warning and treated it as unsigned long.
C90 would reject the damn thing. _Bad_ extension, since in C99 the same
constant would be a legitimate signed long long.
But yes, "use the suffix when unsure" is a damn good idea, _especially_ since
the sizeof(long) actually varies between the targets we care about.

A few sparc64 bug fixes and proper 64-bit rwsem support as you
suggested.
1) Fetching large device properties from openfirmware spams all
over the kernel data section, based upon a report by Meelis
Roos. The fix is to just use the caller's buffers directly
instead of this unnecessary 3k bounce buffer business.
2) The atomic64_t interface 'long' cases I missed.
3) Lock loop backoff didn't really NOP out correctly on UP.
4) Perf control register writes would write the register
twice by mistake due to a missing delay slot nop. Fix
from Mikulas Patocka.
Please pull, thanks a lot!

Actually, there's one more problem; I have a tentative fix for sparc64,
but not for sparc32 (yet).
Basically, sparc is unlike all other architectures in this respect:
normally, after do_signal() has handled a signal the syscall exit
glue loops back, rechecks if we need to be rescheduled, if we need
to deal with more signals, etc. As the result, we build all sigframes
at once. sparc (and, until recently, alpha) normally calls do_signal()
only once; sparc64 _may_ call it twice, but that's it. sparc32 may
call it up to three times if we had userland window spill on entry.
That has unpleasant results - for starters, delivery of SIGSEGV upon
failure to set sigframe up is delayed unpredictably; we will take it
only when we trap again. Moreover, sigsuspend() has inconsistent
behaviour in case when we have several pending signals unmasked by
new mask. E.g. if we do the following on anything but sparc
block signals 1 and 2
set handlers for both
get signals 1 and 2 sent to you
sigsuspend(&emptyset)
we'll get both handlers run. On sparc we'll get only one of them, except
that if we get an IRQ while running in its handler, we'll get both run...
What happens is that sparc (and alpha until it got fixed) sets up one sigframe
and happily buggers off to userland; the first handler runs until we hit
a trap. If that trap happens to be the call of sigreturn() in the end of
handler, the first thing it'll do will be restoring the original sigmask.
Anything else will leave sigmask alone, see that we have another pending
signal and handle it...
Anyway, the sparc64 part of fix follows; I'm still digging through the
sparc32 side of things. Dave, could you take a look at that and ACK or NAK
it?

I think this whole argument is a total red herring.
It's a bug in next_signal() if we allow this to happen. We need to
enqueue those synchronous signals first, and NO AMOUNT OF SIGNAL
QUEUEING will ever change that.
The fact is, even if you queue up all the signals at once, you need to
queue up the synchronous ones first. Otherwise their instruction
pointer information etc will simply be bogus. It's that simple. Your
argument about queuing up one, two, or more signals is bogus, for the
simple reason that it doesn't matter: whether you queue or not is
irrelevant, since the "innermost" one in the queue always has to be
the SIGSEGV.
Whether we queue other signals on top of that (and they get executed
first, since it's a stack) doesn't matter. That's a timing issue, and
the program acts as if those asynchronous signals happened before the
trap. But that's fine. All that matters is that the actual synchronous
signal has the register contents of the time of the synchronous trap,
ie it gets enqueued first.
It's why we have that "if (x & SYNCHRONOUS_MASK)" in next_signal().
It's not pretty, it's not perfect, but it's required.

I think this whole argument is a total red herring.
It's a bug in next_signal() if we allow this to happen. We need to
enqueue those synchronous signals first, and NO AMOUNT OF SIGNAL
QUEUEING will ever change that.
The fact is, even if you queue up all the signals at once, you need to
queue up the synchronous ones first. Otherwise their instruction
pointer information etc will simply be bogus. It's that simple. Your
argument about queuing up one, two, or more signals is bogus, for the
simple reason that it doesn't matter: whether you queue or not is
irrelevant, since the "innermost" one in the queue always has to be
the SIGSEGV.
Whether we queue other signals on top of that (and they get executed
first, since it's a stack) doesn't matter. That's a timing issue, and
the program acts as if those asynchronous signals happened before the
trap. But that's fine. All that matters is that the actual synchronous
signal has the register contents of the time of the synchronous trap,
ie it gets enqueued first.
It's why we have that "if (x & SYNCHRONOUS_MASK)" in next_signal().
It's not pretty, it's not perfect, but it's required.

Um, no. You've *already* called get_signal_to_deliver(). There had been
no SIGSEGV in sight. You happily went on to set a sigframe for e.g.
SIGHUP, but ran out of stack. At that point you get force_sigsegv()
from handle_signal(). _NOW_ you have a pending SIGSEGV; whether you'll
be able to handle it (e.g. if your SIGSEGV handler is set to run on
altstack) or not, you won't get to it until you call get_signal_to_deliver()
again. Which requires do_signal() to run.
Sure, it will be the first one to be picked, but we need to try and pick
_something_ to get it.

PS: on something like x86 that'll happen before we return to userland,
since the glue on syscall exit does that:
int_signal:
testl $_TIF_DO_NOTIFY_MASK,%edx
jz 1f
movq %rsp,%rdi # &ptregs -> arg1
xorl %esi,%esi # oldset -> arg2
call do_notify_resume
1: movl $_TIF_WORK_MASK,%edi
int_restore_rest:
RESTORE_REST
DISABLE_INTERRUPTS(CLBR_NONE)
TRACE_IRQS_OFF
jmp int_with_check
and int_with_check leads back to int_signal if _TIF_SIGPENDING is still set.
That kind of looping happens on everything except sparc and that's exactly
the difference I'm talking about. On sparc the sucker manages to escape
to userland with SIGSEGV still pending. Try it and you'll see - simple
signal(SIGHUP, something) + munmap a little bit under your %sp +
raise(SIGHUP), then look at the resulting coredump... On sparc you'll
get that SIGSEGV later; in fact, putting write(1, "ouch\n", 5); after
that raise() has a good chance of saying ouch before it dumps core.

Ahh. Ok. Different case from the one I thought you were worried about.
And yeah, I guess that one does require us to mess with the low-level
asm code (although I do wonder if we could not make the whole
do_notify_resume + reschedule code be generic C code - it's a lot of
duplicated subtle asm as it is).

Worse than just that... Note that on sparc you need to deal with
fault_in_user_windows(), which can also trigger signals. So much
for merging it cross-architecture, even if we ignore the differences
between the ways we pass data required for restart to do_signal().
Note that e.g. on alpha we pass _two_ values - one for overwritten
v0 (syscall number), another for overwritten a3 (error flag), etc.
Worse, quite a few targets do not save all registers on syscall entry.
Callee-saved stuff doesn't have to be in pt_regs. Except that you
want *all* of them saved on stack when it's time to fill sigframes.
And once you've entered a C function you can't guarantee that compiler
hasn't already modified them; sure, they'll be restored on return, but
that doesn't help you to get to their values. So you get switch_stack
built on stack around calling do_notify_resume() on those. And you
really want to avoid doing that if you've got no signals - remember,
we hit that on exit from irqs as well, so it's one hell of a hot path.
For processors with big flat register file it can get very ugly.
There is a lot of ugly almost-duplication in there, no arguments about that.
Asm glue is actually not the worst part...

Actually, I wonder why don't we do the following:
1) check wsaved first, do fault_in_user_windows() if needed (and probably do
Something Cruel(tm) if we fail copy_to_user() in there)
2) in a loop check if we need to reschedule / if we need to handle signals
3) don't bother with wsaved checks in setup_frame() variants at all -
wsaved can't grow back at that point; we also can use flush_user_windows()
instead of full synchronize_user_stack() in there.
It's definitely a separate patch, but it looks like it might be worth
doing... Comments?

Ok, let me think about this.
I think there are two things:
1) I think I originally intended to allow the signal dispatch to
succeed even if we had windows we couldn't fault in.
The idea is that the wsaved windows would be put into the signal
frame.
This never was implemented, however...
2) It would be nice to, in this case, still be able to let the debugger
have a look.
And part of "having a look" would mean letting it see the registers
from the windows we couldn't save onto the stack.
Otherwise GDB is just going to try and access the stack pages we
were unable to.
Making #2 work could be done with an implementation of #1, since GDB
would need to be able to fetch the values easily from somewhere and
the signal frame storage we create for #1 would be as good as any.
I can't see much utility for a user signal handler for #1, however,
other than getting an accurate stack backtrace to emit a crash log
message or similar.
Alternatively, #2 could be implemented using a special ptrace getregs
call created specifically to fetch the windowed registers. And
the regset implementation of that could be used for dumping them
into core files as well, and this specifically I've been meaning to
do at some point.
Again, let me think about this some more.

would need to be able to fetch the values easily from somewhere and
the signal frame storage we create for #1 would be as good as any.
I can't see much utility for a user signal handler for #1, however,
other than getting an accurate stack backtrace to emit a crash log
message or similar.
Alternatively, #2 could be implemented using a special ptrace getregs
call created specifically to fetch the windowed registers. And
the regset implementation of that could be used for dumping them
into core files as well, and this specifically I've been meaning to
do at some point.
Again, let me think about this some more.

OK... sparc32 question: just what the !@#!@# happens if sun4c_rett_stackchk
find (%fp & 7) != 0? We go to ret_trap_user_stack_is_bolixed, which
tries to page in the underlying page. OK, suppose it's already there and
readable; we return without doing anything - and go to signal_p. Which finds
itself with nothing to do, and %fp is *still* buggered. Spin ad infinitum?
srmmu_rett_stackchk will do the same, BTW...

That's a bug.
Likely all of the window_*_fault() routines should force a SIGILL when
the stack is mis-aligned.

Dave, are you OK with the following patch? That should cover both sparc32
and sparc64...
Subject: [PATCH] sparc: keep calling do_signal() as long as pending signals remain
Analog of what commit 494486a1d2697f2153199b6501ab5b4d6e15a2bb had done
to alpha (another architecture with similar bug).
One note: in rtrap_32.S part clr %l6 has been a rudiment of left after
commit 28e6103665301ce60634e8a77f0b657c6cc099de (sparc: Fix debugger syscall
restart interactions) has killed %l6 use in there.

Looks great, I'll apply this and give it some of my own testing.
I'll also take care of that unaligned stack pointer issue on sparc32.

BTW, there's an interesting idea in s390 implementation (and I have to say
that I'm bloody impressed by them - it's the only architecture besides x86
where I haven't found serious holes in signal handling yet; there are QOI
issues, but that's it so far). What they do with syscall restarts is unusual
and they might have a good point there.
1) They deal with restart immediately on the entry to do_signal(); if
restarts are not suppressed and if the error is one of the restart-worthy
ones, they do what should be done for no-handler case.
2) They store the pre-restart address, post-restart address and error. Then
they call get_signal_to_deliver(). Of course, it may return us a positive
signal number. In that case they may need to discard the restart they'd
done. And they do it, but only if the address has remained equal to
post-restart one.
3) They ignore ERESTART_RESTARTBLOCK if the address has changed. Actually,
I suspect that they might need to clear the ->restart_block.fn in that case,
but I haven't done analysis of that yet.
They do have a reason for doing it that way and it's worth considering on
other platforms. Think what happens if we are getting traced. We'll be
stopped and tracer will be notified. Normally it'll tell us to continue
execution, possibly with a different signal *AND* with a different userland
address to return to. Suppose we've got a different return address set
for us (e.g. with PTRACE_POKEUSR). Should we ever shift it back by what
hopefully is a size of syscall insn?

These "tracer changing the program counter" issues are why on sparc we
have this software state bit in the %tstate/%psr we report via regsets
(and thus via ptrace) to debuggers which tells if we are inside of a
syscall or not.
GDB uses this to know whether the kernel signal handling is going to
modify the program counter or not when the inferior continues.
If GDB ever writes the program counter of the inferior, it clears
this "in-syscall" bit, and this short-circuits the restart syscall
logic in the signal dispatch code.
This is what the GDB code looks like:
static void
sparc_linux_write_pc (struct regcache *regcache, CORE_ADDR pc)
{
struct gdbarch_tdep *tdep = gdbarch_tdep (get_regcache_arch (regcache));
ULONGEST psr;
regcache_cooked_write_unsigned (regcache, tdep->pc_regnum, pc);
regcache_cooked_write_unsigned (regcache, tdep->npc_regnum, pc + 4);
/* Clear the "in syscall" bit to prevent the kernel from
messing with the PCs we just installed, if we happen to be
within an interrupted system call that the kernel wants to
restart.
Note that after we return from the dummy call, the PSR et al.
registers will be automatically restored, and the kernel
continues to restart the system call at this point. */
regcache_cooked_read_unsigned (regcache, SPARC32_PSR_REGNUM, &psr);
psr &= ~PSR_SYSCALL;
regcache_cooked_write_unsigned (regcache, SPARC32_PSR_REGNUM, psr);
}

have this software state bit in the %tstate/%psr we report via regsets
(and thus via ptrace) to debuggers which tells if we are inside of a
syscall or not.
GDB uses this to know whether the kernel signal handling is going to
modify the program counter or not when the inferior continues.
If GDB ever writes the program counter of the inferior, it clears
this "in-syscall" bit, and this short-circuits the restart syscall
logic in the signal dispatch code.
This is what the GDB code looks like:
static void
sparc_linux_write_pc (struct regcache *regcache, CORE_ADDR pc)
{
struct gdbarch_tdep *tdep = gdbarch_tdep (get_regcache_arch (regcache));
ULONGEST psr;
regcache_cooked_write_unsigned (regcache, tdep->pc_regnum, pc);
regcache_cooked_write_unsigned (regcache, tdep->npc_regnum, pc + 4);
/* Clear the "in syscall" bit to prevent the kernel from
messing with the PCs we just installed, if we happen to be
within an interrupted system call that the kernel wants to
restart.
Note that after we return from the dummy call, the PSR et al.
registers will be automatically restored, and the kernel
continues to restart the system call at this point. */
regcache_cooked_read_unsigned (regcache, SPARC32_PSR_REGNUM, &psr);
psr &= ~PSR_SYSCALL;
regcache_cooked_write_unsigned (regcache, SPARC32_PSR_REGNUM, psr);
}

This fixes two bugs.
First a fix from Daniel Hellstrom that eliminates a hard-coded HZ
constant in the LEON code.
Second, fix a regression in sparc64 firmware calls.
Some kinds of firmware calls are not safe to pass buffer addresses
over 4GB, they really aren't 64-bit safe universally especially on
older sparc64 systems.
So I fixed this in two steps:
1) Remove firmware interfaces unused by the kernel right now, which is
safer than trying to recode them to use bounce buffers or similar.
2) Add a bounce buffer for PROM console writes to ensure that the
buffer restrictions are met.
Tested successfully by the original bug reporter.
Please pull, thanks a lot!

Three sparc32 bug fixes here:
1) Correct unaligned pointer determination in sparc32 checksumming asm
code, from Tkhai Kirill.
2) Sparc5 bootup busted because of incorrect CPU ID probing, fix from
Sam Ravnborg.
3) Bad __init markings cause references to freed up memory after bootup,
also from Sam Ravnborg.

Three sparc32 bug fixes here:
1) Correct unaligned pointer determination in sparc32 checksumming asm
code, from Tkhai Kirill.
2) Sparc5 bootup busted because of incorrect CPU ID probing, fix from
Sam Ravnborg.
3) Bad __init markings cause references to freed up memory after bootup,
also from Sam Ravnborg.
Please pull, thanks a lot!

Sparc32 enters the modern age thanks to Sam Ravnborg and
Daniel Hellstrom.
Sparc32 now supports genirq, and it now properly generates
IPIs.
Plus some LEON updates from Daniel Hellstrom as well.

Just a few more Niagara T3 refinements as well as several
bug fixes, including:
1) On sun4v we need to access the TSB using physical addresses otherwise
we can read/write different data than what the hypervisor and/or
the hardware TSB walker does.
2) sparc32 __atomic_add_unless return value needs correction, from
Josip Rodin.
3) Sun4v cpu mondo queue sizes could be way too large, and we'd fail
to allocate them because the page allocation order would exceed
MAX_ORDER. Set a sane cap to fix the problem.
4) Sam Ravnborg's patch to use kbuild-generic.
5) Use the hypervisor interface to set the 'reboot-cmd' variable so
that rebooting into the correct image works even if the service
processor is dead or in degraded mode.
Please pull, thanks a lot!

2) Sparc should use the C based recordmcount, thanks to Steven Rostedt
for the tip.

Several bug fixes:
1) Make syscall restart properly save and restore the first argument
register across possible ptrace modifications.
2) Implement sparc's io_remap_pfn_range() in terms of remap_pfn_range().
A ton of divergance has occured over time and it makes no sense to
have a completely seperate loop for what amounts to being a very
minor optimization on sparc64.
3) Because modules can use things like pgprot_noncached() and friends,
we have to process the sun4v code patching sections upon module
load on sparc64. This fixes crashes with infiniband on Niagara
machines.
4) Missing header include, from Ben Hutchings.
Please pull, thanks a lot!

Several bug fixes:
1) Make syscall restart properly save and restore the first argument
register across possible ptrace modifications.
2) Implement sparc's io_remap_pfn_range() in terms of remap_pfn_range().
A ton of divergance has occured over time and it makes no sense to
have a completely seperate loop for what amounts to being a very
minor optimization on sparc64.
3) Because modules can use things like pgprot_noncached() and friends,
we have to process the sun4v code patching sections upon module
load on sparc64. This fixes crashes with infiniband on Niagara
machines.
4) Missing header include, from Ben Hutchings.
Please pull, thanks a lot!

1) Bootup on 32-bit fails because gcc started to emit tail calls more
aggressively, so we need to accept 13-bit signed immediation
relocations into 'restore' instructions.
2) Kill unused variable in bbc_i2c and module_platform_driver()

3) Use kmemdup(), from Thomas Meyer.

I did not fix sparc32 build - will look at it later today.
I assume it is equally trivial to fix.

Oh christ. You're teaching *more* people about sparc64?
Where will it end?
That said, Looking at the patch, it looks a bit dubious. Why does the
cmp %l1, 0
instruction remain, even if the conditional branch was deleted? I'm
not seeing any subsequent uses of %icc, but hey, I'm no sparc expert
(nor do I want to be).

It's unnecessary but harmless, I'll sweep it up in the sparc-next tree
when I get a chace.

You do not get it...
How many people are pondering around tweaking every bit of x86
specific code? A lot! Let them have fun competing :-)
In sparc land things are much more quiet.
And there are some nice tasks to be done that is good for the kernel,
as users of old cruft is sometimes hindering forward progress.
And when one is away for a few months things has not dramatically
changed since last you looked.

I wish it was so! In reality there's really just a handful of
people looking at actual x86 assembly code. I don't know whether
I've ever seen a conflict between substantial x86 assembly
patches, in the last 4 years since I co-maintain the x86
architecture ...
So there's no competition worth speaking of in x86 assembly
land, let alone any harmful competition due to overcrowding.
You guys are all welcome, and each of you will make a real
difference.
Imagine what would happen to Linux adoption rate if DaveM
started hacking on assembly code that had more than a few
dozen active users?? ;-)
> In sparc land things are much more quiet.
I guess when you are close to absolute zero degrees then even
liquid oxygen indeed looks incredibly hot ;-)

Hmm...
lines of c files lines of S files
x86 183609 27130
sparc 66823 25852
There is more than just assembly when dealign with an architecture.
And honestly I do not "speak" neither sparc nor x86 assembly.

1) Kill off support for sun4c and Cypress sun4m chips.
And as a result we were able to also kill off that ugly
btfixup thing that required multi-stage links of the final
vmlinux image in the Kbuild system. This should make the
kbuild maintainers really happy.
Thanks a lot to Sam Ravnborg for his tireless efforts to
get this going.
2) Convert sparc64 to nobootmem. I suspect now with sparc32
being a lot cleaner, it should be able to fall in line and
modernize in this area too.
3) Make sparc32 use generic clockevents, from Tkhai Kirill.
There is going to be a merge conflict between the commit in the
net-next tree that adds the Sparc BPF JIT, and the one in here which
adds arch/sparc/Kbuild. It should be quite easy to resolve.
Please pull, thanks a lot!

Ok, so that had a very obvious resolution, and a "cleaner, but scarier" version.
I picked the cleaner but scarier one - the one that should make the
BFP JIT be built when you do "make arch/sparc" by putting the net
thing into the new arch/sparc/Kbuild file.
I did minimal testing with "make ARCH=sparc" without actually
*building* anything, and in the process also fixed the fact that you
should not select HAVE_BPF_JIT unless networking is enabled (crappy
interface - maybe that "if NET" part really should be in the
HAVE_BPF_JIT rules, not in all the architectures?)
But I do not have (nor do I really want) a sparc cross-compile
environment, so maybe my "cleaner" resolution is just garbage. Can you
please check the end result?
So if I broke something, please call me names and tell me to not try
to think too much, and worry my little brain with things I don't
understand.
The thing is pushed out, so you can see what I did.

HAVE_BPF_JIT is only used to make the BPF_JIT prompt visible.
And BPF_JIT depends on NET.
So the "if NET" part in the select is redundant but not strictly wrong.

It's not redundant.
Try doing a "make ARCH=sparc allnoconfig" without it. It will warn.
I didn't bother looking at *why* it warns, but all other architectures
have the "if NET" part.

Ok, I looked now, and it's because the definition of HAVE_BPF_JIT is
inside the "if NET" thing.
So if NET isn't enabled, then HAVE_BPF_JIT doesn't really *exist* as
an option. Doing a "select" on it is thus not a good idea.
I bet you could just move the two lines
config HAVE_BPF_JIT
bool
up to the top of net/Kconfig (so that HAVE_BPF_JIT is available
unconditionally), and then remove all the "if NET" from the four
architectures that support it.

Subject: [PATCH] net: drop NET dependency from HAVE_BPF_JIT
There is no point having the NET dependency on the select target,
as it forces all users to depend on NET to tell they support BPF_JIT.
Move the config option to the bottom of the file - this
could be a nice place also for future "selectable" config symbols.
Fix up all users to drop the dependency on NET now that
it is not required to supress warnings for non-NET builds.

Do you want me to take this directly, or will it go through the net

I see. This is because HAVE_BPF_JIT depends on NET, so kconfig
warns if you select HAVE_BPF_JIT without NET enabled.
The correct fix is obviously to move HAVE_BPF_JIT so it
does not depend on NET.
Sprinkling "if NET" all over is the wrong fix.

1) Remove the idiotic situation wherein Leon was a special
case in all of the TLB/cache handling code.
The worst side effect of this bogosity is that you couldn't build a
kernel with Leon support enabled (to get better build coverage),
and test boot it on a non-LEON cpu.
Leon is, in all core respects, programatically identical to the
32-bit SRMMU. Except that they put the TLB registers in a
different alternate address space location.
Through code patching (for fast paths) and run time checks, this
issue is now a thing of the past.
From Sam Ravnborg.
2) There was a mis-merge of arch/sparc/Kconfig for one of the
clockevents changes that went in, causing 32-bit sparc to
start failing to build.
I merged in your tree to get those clockevents changes (and
added a note to the merge commit) then added Stephen Rothwell's
fix for the merge error.
3) Software quad floating point emulation was not working properly
on more recent Niagara chips, because the way the situation is
reported by the cpu has changed.
Nobody noticed because gcc emits calls to software emulation
routines in glibc.
Please pull, thanks a lot!

This just removes some sparc headers that were never, ever, used.
Please pull, thanks a lot!

Nothing much this merge window for sparc.
1) Fix FPU state management in sparc32, from Tkhai Kirill.
2) More sparc32 mm layer code cleanups, largely more side effects
of the sun4c support removal in the 3.5 From Sam Ravnborg.
3) Remove unused code in sparc64, from Bjorn Helgaas and Kirill Tkhai.
4) Some declaration and comment tidies in PROM support code, from
Geert Uytterhoeven.
Please pull, thanks a lot!

1) Debugging builds on 32-bit sparc need to handle the R_SPARC_DISP32
relocation, not just 64-bit sparc. From Andreas Larsson.
2) Wei Yongjun noticed that module_alloc() on sparc can return an
error pointer, but that's not allowed. module_alloc() should
return only a valid pointer, or NULL.

Largely this is simply adding support for the Niagara 4 cpu.
Major areas are perf events (chip now supports 4 counters and
can monitor any event on each counter), crypto (opcodes
are availble for sha1, sha256, sha512, md5, crc32c, AES, DES,
CAMELLIA, and Kasumi although the last is unsupported since
we lack a generic crypto layer Kasumi implementation), and.
an optimized memcpy.
Finally some cleanups by Peter Senna Tschudin.
Please pull, thanks a lot.

we lack a generic crypto layer Kasumi implementation), and.
an optimized memcpy.
Finally some cleanups by Peter Senna Tschudin.

Some quick fixes after today's merge-window pull.
1) Add missing dependency on Sparc DES driver, oops.
From Dave Jones.
2) Tell GCC that prom_printf() is printf-like and fix the few
resultiing warnings. From Akinobu Mita.
3) Niagara-2 memcpy doesn't provide it's return value correctly
in some circumstances.

There is an attempt to fix a bad interaction between syscall tracing
and force_successful_syscall() from Al Viro, but it needs to be redone
as it introduced regressions and thus had to be reverted for now.
Al is working on an updated version.
But what we do have here are some significant bzero/memset
improvements for Niagara-4. An 8K page can be cleared in around 600
cycles, because we essentially have a store that behaves like
powerpc's dcbz that we can actually make real use of.
Please pull, thanks a lot.

See below. Just in case: Linus, please DO NOT APPLY unless it goes through
sparc tree - this is modulo approval by davem.
sparc64: fix ptrace interaction with force_successful_syscall_return()
we want syscall_trace_leave() called on exit from any syscall;
skipping its call in case we'd done force_successful_syscall_return()
is broken...

Several build/bug fixes for sparc, including:
1) Configuring a mix of static vs. modular sparc64 crypto modules
didn't work, remove an ill-conceived attempt to only have to build
the device match table for these drivers once to fix the problem.
Reported by Meelis Roos.
2) Make the montgomery multiple/square and mpmul instructions actually
usable in 32-bit tasks. Essentially this involves providing 32-bit
userspace with a way to use a 64-bit stack when it needs to.
3) Our sparc64 atomic backoffs don't yield cpu strands properly on
Niagara chips. Use pause instruction when available to achieve
this, otherwise use a benign instruction we know blocks the
strand for some time.
4) Wire up kcmp
5) Fix the build of various drivers by removing the unnecessary
blocking of OF_GPIO when SPARC.
6) Fix unintended regression wherein of_address_to_resource stopped
being provided. Fix from Andreas Larsson.
7) Fix NULL dereference in leon_handle_ext_irq(), also from Andreas
Larsson.
Please pull, thanks a lot.

Two small fixes for Sparc, nobody uses sparc, so these are
low risk :-)
1) Piggyback is too picky about the symbol types that _start
and _end have in the final kernel image, and it thus breaks
with newer binutils. Future proof by getting rid of the
symbol type checks.
2) exit_group() should kill register windows on sparc64 the same
way we do for plain exit(). Thanks to Al Viro for spotting
this.
Please pull, thanks a lot!

Please pull to get these sparc AES/DES/CAMELLIA crypto bug fixes
as well as an addition of a pte_accessible() define for sparc64
and a hugetlb fix from Dave Kleikamp.
Thanks.

A couple small fixes for sparc including some THP brown-paper-bag
material:
1) During the merging of all the THP support for various architectures,
sparc missed adding a HAVE_ARCH_TRANSPARENT_HUGEPAGE to it's Kconfig,
oops.
2) Sparc needs to be mindful of hugepages in get_user_pages_fast().
3) Fix memory leak in SBUS probe, from Cong Ding.
4) The sunvdc virtual disk client driver has a test of the bitmask of
vdisk server supported operations which was off by one bit.
Please pull, thanks a lot!

Couple small bug fixes:
1) strlcpy in ldom_reboot() is still not quite right, use sprintf
instead from Kees Cook.
2) Generic hugetlb interface pte checks should use the widest return
type, otherwise high bits can get chopped off.

Couple small bug fixes:
1) strlcpy in ldom_reboot() is still not quite right, use sprintf
instead from Kees Cook.
2) Generic hugetlb interface pte checks should use the widest return
type, otherwise high bits can get chopped off.
3) Fix build with PCI MSI enabled on 32-bit sparc.
Please pull, thanks a lot!

There is a minor conflict with patches Andrew submitted to you today,
one of his patches is fixing the error handling in the sparc64 page
table SLAB handling, whereas the 47-bit physical address support patch
series in this pull request deletes all of the sparc64 page table SLAB
code entirely.
So just take the removal in your merge conflict resolution.
1) Implement support for up to 47-bit physical addresses on sparc64.
2) Support HAVE_CONTEXT_TRACKING on sparc64, from Kirill Tkhai.
3) Fix Simba bridge window calculations, from Kjetil Oftedal.
Please pull, thanks a lot!

2) Use dev_is_pci() where applicable, from Yijing Wang.
3) Enable irqs after we enable preemption in cpu startup path,
from Kirill Tkhai.
4) Revert a __copy_{to,from}_user_inatomic change that broke
iov_iter_copy_from_user_atomic() and thus several tests in
xfstests and LTP. From Dave Kleikamp.

Hi Dave,
It seems like forever you go you sent me patches to trinity to make it
work on sparc. I'm curious if you've tried running it again more
recently ? Given the work I've done it to do more creative things with
VM related syscalls, I wouldn't be surprised if it also found some sparc
specific bugs in thp.
It should now also scale up to run a lot more child processes than the older
version, with the -c option, which could be interesting on some of the
bigger sparc machines.
(It's entirely possible I've broken the compile on non-x86 in
current git, but it shouldn't be much work to fix up).
git://github.com/kernelslacker/trinity is where it lives now.

A small bunch of bug fixes, in particular:
1) On older cpus we need a different chunk of virtual address
space to map the huge page TSB.
2) Missing memory barrier in Niagara2 memcpy.
3) trinity showed some places where fault validation was unnecessarily
loud on sparc64
4) Some sysfs printf's need a type adjustment, from Toralf Förster

1) Add sparc RAM output to /proc/iomem, from Bob Picco.
2) Allow seeks on /dev/mdesc, from Khalid Aziz.
3) Cleanup sparc64 I/O accessors, from Sam Ravnborg.
4) If update_mmu_cache{,_pmd}() is called with an not-valid mapping,
do not insert it into the TLB miss hash tables otherwise we'll
livelock. Based upon work by Christopher Alexander Tobias Schulze.
5) Fix BREAK detection in sunsab driver when no actual characters
are pending, from Christopher Alexander Tobias Schulze.
6) Because we have modules --> openfirmware --> vmalloc ordering of
virtual memory, the lazy VMAP TLB flusher can cons up an invocation
of flush_tlb_kernel_range() that covers the openfirmware address
range. Unfortunately this will flush out the firmware's locked
TLB mapping which causes all kinds of trouble. Just split up
the flush request if this happens, but in the long term the lazy
VMAP flusher should probably be made a little bit smarter.
Based upon work by Christopher Alexander Tobias Schulze.

1) Move to 4-level page tables on sparc64 and support up to 53-bits of
physical addressing. Kernel static image BSS size reduced by
several megabytes.
2) M6/M7 cpu support, from Allan Pais.
3) Move to sparse IRQs, handle hypervisor TLB call errors more
gracefully, and add T5 perf_event support. From Bob Picco.
4) Recognize cdroms and compute geometry from capacity in virtual
disk driver, also from Allan Pais.
5) Fix memset() return value on sparc32, from Andreas Larsson.
6) Respect gfp flags in dma_alloc_coherent on sparc32, from Daniel
Hellstrom.
7) Fix handling of compound pages in virtual disk driver, from Dwight
Engen.
8) Fix lockdep warnings in LDC layer by moving IRQ requesting to
ldc_alloc() from ldc_bind().
9) Increase boot string length to 1024 bytes, from Dave Kleikamp.
Please pull, thanks a lot!

Here we have two bug fixes:
1) The current thread's fault_code is not setup properly upon entry to
do_sparc64_fault() in some paths, leading to spurious SIGBUS.
2) Don't use a zero length array at the end of thread_info on sparc64,
otherwise end_of_stack() isn't right.
Please pull, thanks!

Please pull to get these two bug fixes:
1) Fix boots with gcc-4.9 compiled sparc64 kernels.
2) Add missing __get_user_pages_fast() on sparc64 to fix hangs
on futexes used in transparent hugepage areas.
It's really idiotic to have a weak symbolled fallback that just
returns zero, and causes this kind of bug. There should be no
backup implementation and the link should fail if the architecture
fails to provide __get_user_pages_fast() and supports transparent
hugepages.

Agreed. I think the weak fallback is for the "no hugepages support"
case, but that does sound very annoying and fragile.

Yup. I'm thinking the get_user_pages_fast() and
__get_user_pages_fast() in mm/util.c should be made non-weak and moved
to mm/nommu.c.
With that change, MMU architctures will need to either define
CONFIG_HAVE_GENERIC_RCU_GUP or implement their own versions.
Perhaps sparc should be defining CONFIG_HAVE_GENERIC_RCU_GUP.
We really should switch x86 to the generic version - from a quick read
it looks like it will work without needing any changes.
Steve, thoughts?

Yup. I'm thinking the get_user_pages_fast() and
__get_user_pages_fast() in mm/util.c should be made non-weak and moved
to mm/nommu.c.
With that change, MMU architctures will need to either define
CONFIG_HAVE_GENERIC_RCU_GUP or implement their own versions.
Perhaps sparc should be defining CONFIG_HAVE_GENERIC_RCU_GUP.
We really should switch x86 to the generic version - from a quick read
it looks like it will work without needing any changes.
Steve, thoughts?

We need to add the necessary hooks to the generic code so that x86
doesn't so specualtive gets and instead do direct increments,
otherwise it's a performance regression, and then sparc can make use
of that as well.

Agreed, I think x86 may require a helper to read 64-bit ptes (as it
can't do that atomically). Also I think there's some subtlety in the
way access_ok works that should be checked.
The overall structure of the code looks the same to me, and I think it
would be beneficial to extend then use the generic version for x86.
Cheers,

Two changes:
1) It makes no sense to execute a VTOC partition table request
in the Sun virtual block device driver and fail to load if it
doesn't succeed because a) we don't use the result at all and
b) it won't succeed if there is an EFI partition on the disk,
for example.
We read the partition table via the normal means in the block
layer anyways, so this is really completely useless, so just
remove it.
From Dwight Engen.
2) Hook up new bpf system call.

Here we have:
1) Fix NULL oops in Schizo PCI controller error handler.
2) Fix race between xchg and other operations on 32-bit sparc, from
Andreas Larsson.
3) swab*() helpers need a dummy memory input operand to show data flow
on 64-bit sparc.
4) Fix RCU warnings due to missing irq_{enter,exit}() around
generic_smp_call_function*() calls.

That doesn't seem to be marked for stable? Or do you do the same thing
as for networking, and just collect stable patches manually?

Side note: the memmove commit message is a bit misleading. The old
code handled zero-length calls fine, even if it wasn't explicit: it
always called memmove() for that case.
The condition "dst <= src || src + len <= dst" ends up being always
true when len is zero (because it obviously ends up being "dst <= src
|| src <= dst").
So there was just one bug - the 64-byte overlap with the cacheline
establish for the destination. Even that cacheline establish would
have been ok if all the loads for the 64-byte block had been done
up-front.
Oh well. I'm actually somewhat surprised this didn't hit anything
else. Doesn't networking also end up doing overlapping memmove() on
the skb data occasionally?

The only case I can think of is when {en,de}capsulating VLANs in
software.
But those are really small header sized copies, and would never
trigger the unrolled loop which requires len >= 128.
A quick grep shows something similar for wireless WEP/WPA, but not
only are these small copies too but I don't have any wireless on
any of my sparc boxes :-)
It really is just SLAB/SLUB with large NR_CPU configurations.

The PowerPC folks have a really nice scalable IOMMU pool allocator
that we wanted to make use of for sparc. So here we have a series
that abstracts out their code into a common layer that anyone can
make use of.
Sparc is converted, and the PowerPC folks have reviewed and ACK'd
this series and plan to convert PowerPC over as well.
Please pull, thanks a lot!

Unfortunately, I brown paper bagged the generic iommu pool
allocator by applying the wrong revision of the patch series.
This reverts the bad one, and puts the right one in.

1) ldc_alloc_exp_dring() can be called from softints, so use GFP_ATOMIC.
From Sowmini Varadhan.
2) Some minor warning/build fixups for the new iommu-common code on

1) ldc_alloc_exp_dring() can be called from softints, so use GFP_ATOMIC.
From Sowmini Varadhan.
2) Some minor warning/build fixups for the new iommu-common code on
certain archs and with certain debug options enabled. Also from
Sowmini Varadhan.
Please pull, thanks!

1) Setup the core/threads/sockets bitmaps correctly so that 'lscpus' and friends
operate properly. Frtom Chris Hyser.
2) The bit that normally means "Cached Virtually" on sun4v systems,
actually changes meaning in M7 and later chips. Fix from Khalid
Aziz.
3) One some PCI-E systems we need to probe different OF properties
to fill in the PCI slot information properly, from Eric Snowberg.
4) Kill an extraneous memset after kzalloc(), from Christophe Jaillet.
Please pull, thanks a lot!

Just a couple of fixes/cleanups:
1) Correct NUMA latency calculations on sparc64, from Nitin Gupta.
2) ASI_ST_BLKINIT_MRU_S value was wrong, from Rob Gardner.
3) Fix non-faulting load handling of non-quad values, also from Rob
Gardner.
4) Cleanup VISsave assembler, from Sam Ravnborg.
5) Fix iommu-common code so it doesn't emit rediculous warnings
on some architectures, particularly ARM.

Heh. So looking at that patch, I can't but help to react that this:
#define IOMMU_ERROR_CODE (~(unsigned long) 0)
is still pretty ridiculous. Maybe just (-1ul), or for those people
who don't understand C unsigned long arithmetic and think that a
negative unsigned long looks odd, (~0ul)?
Not that this *matters*, but it's a bit odd to have to cast constants
to perfectly regular C types.

Looking around with "git grep", there's a few more of these.
- btrfs seems to like "(unsigned long)-1"
There's a few other users of that too, including more sparc uses.
- scsi/qla seems to like "(unsigned long)<hexnumber>"
- fmdrv_common.h seems to like "((unsigned long)1<<x)" for bitmaps
along with a smattering of random noise all over of "(unsigned long)
n" where 'n' is some integer.
Apparently people aren't as aware of the normal "ul" postfix syntax as
I would have expected. That said, it's a hundred-odd cases in all of
the kernel, so it's still fairly rare.

Maybe this is something the kernel-janitors team should look at? (CC'd)

Maybe this is something the kernel-janitors team should look at? (CC'd)

Do you have some concrete examples of the code that is undesirable?

Joe Perches produced a patch for checkpatch to check for this [1]
Linus was complaining [2] about people producing constants with casts
to basic C types in them. For instance:
#define IOMMU_ERROR_CODE (~(unsigned long) 0)
This could be replaced with
#define IOMMU_ERROR_CODE (~0ul)
or potentially
#define IOMMU_ERROR_CODE (-1ul)
It's not overly common, but it looks wrong.

So add a test that looks for constants that are cast to
standard C90 int or longer types and suggest using C90
"6.4.4.1 Integer constants" integer-suffixes instead.
Miscellanea:
o Add a --fix option too

Yeah I struggled with this, believe it or not.
The expression causing the problem was (~(dma_addr_t) 0) (AKA
DMA_ERROR_CODE) being used as the return value.
So I just replicated that expression. A neuron did fire saying "hey

Yeah I struggled with this, believe it or not.
The expression causing the problem was (~(dma_addr_t) 0) (AKA
DMA_ERROR_CODE) being used as the return value.
So I just replicated that expression. A neuron did fire saying "hey
pinhead, why not just use ~0UL" but I did not listen to the little
voice in my head this time.

Please pull to get the following sparc bug fixes:
1) Finally make perf stack backtraces stable on sparc, several
problems (mostly due to the context in which the user copies
from the stack are done) contributed to this.
From Rob Gardner.
2) Export ADI capability if the cpu supports it.
3) Hook up userfaultfd system call.
4) When faults happen during user copies we really have to
clean up and restore the FPU state fully. Also from
Rob Gardner.
Please pull, thanks a lot!

1) Fix section mismatches in some builds, from Paul Gortmaker.
2) Need to count huge zero page mappings when doing TSB sizing,
from Mike Kravetz.
3) Fix handing of cpu_possible_mask when nr_cpus module option
is specified, from Atish Patra.
4) Don't allocate irq stacks until nr_irqs has been processed,
also from Atish Patra.

Several sparc64 bug fixes here:
1) Make the user copy routines on sparc64 return a properly accurate
residual length when an exception occurs.
2) We can get enormous kernel TLB range flush requests from vmalloc
unmaps, so handle these more gracefully by doing full flushes
instead of going page-by-page.
3) Cope properly with negative branch offsets in sparc jump-label
support, from James Clarke.
4) Some old-style decl GCC warning fixups from Tobias Klauser.

1) With modern networking cards we can run out of 32-bit DMA space, so
support 64-bit DMA addressing when possible on sparc64. From Dave
Tushar.
2) Some signal frame validation checks are inverted on sparc32, fix from
Andreas Larsson.
3) Lockdep tables can get too large in some circumstances on sparc64,
add a way to adjust the size a bit. From Babu Moger.
4) Fix NUMA node probing on some sun4v systems, from Thomas Tai.

Please pull to get these Sparc bug fixes:
1) Block interrupts properly across the entire MMU context change
(both the hw MMU context change and the TSB table change) so
that we don't get a perf event interrupt in the middle. From
Rob Gardner.
2) Be sure to register hugepages early enough, from Nitin Gupta.
3) UltraSPARC-III user copy exception handling would return garbage
for the copied length in some circumstances.

Just a couple small fixes, two of which have to do with gcc-7:
1) Don't clobber kernel fixed registers in __multi4 libgcc helper.
2) Fix a new uninitialized variable warning on sparc32 with gcc-7,
from Thomas Petazzoni.
3) Adjust pmd_t initializer on sparc32 to make gcc happy.
4) If ATU isn't avoid, don't bark in the logs. From Tushar Dave.
Please pull, thanks a lot.

1) Add support for ADI (Application Data Integrity) found in more recent
sparc64 cpus. Essentially this is keyed based access to virtual memory,
and if the key encoded in the virual address is wrong you get a trap.
The mm changes were reviewed by Andrew Morton and others.
Work by Khalid Aziz.
2) Validate DAX completion index range properly, from Rob Gardner.
3) Add proper Kconfig deps for DAX driver. From Guenter Roeck.
Please pull, thanks a lot.

1) Add support for ADI (Application Data Integrity) found in more recent
sparc64 cpus. Essentially this is keyed based access to virtual memory,
and if the key encoded in the virual address is wrong you get a trap.
The mm changes were reviewed by Andrew Morton and others.
Work by Khalid Aziz.
2) Validate DAX completion index range properly, from Rob Gardner.
3) Add proper Kconfig deps for DAX driver. From Guenter Roeck.
Please pull, thanks a lot.

There is a merge conflict here, just take the "HEAD" hunks and it
will all work out. It's because I applied a signal code fix that
was already merged and then other cleanups/changes happend on top.
Other than that, this adds the privileged ADI driver from Tom
Hromatka.

I've been moving so haven't had access to my Sparc boxes during this
time. That's been resolved, and now I can get the patches flowing
again.
1) Minor fallthru comment tweaks from Gustavo A. R. Silva.
2) VLA removal from Kees Cook.
3) Make sparc vdso Makefile match x86, from Masahiro Yamada.
4) Fix clock divider programming in mach64 driver, from Mikulas
Patocka.
Please pull, thanks a lot!

I've been moving so haven't had access to my Sparc boxes during this
time. That's been resolved, and now I can get the patches flowing
again.
1) Minor fallthru comment tweaks from Gustavo A. R. Silva.
2) VLA removal from Kees Cook.
3) Make sparc vdso Makefile match x86, from Masahiro Yamada.
4) Fix clock divider programming in mach64 driver, from Mikulas
Patocka.
Please pull, thanks a lot!

Great to hear you're back!
Can I bring this bug [1] back to your attention which allowed a regular
userland application to crash the kernel? Would be interesting to see
whether you're able to reproduce the issue.
The offending binary is attached to the bug report. It's a test program
from the testsuite of the Free Pascal Compiler which was recently ported
to sparc64.
Thanks,
Adrian

1) Revert the %pOF change, it causes regressions.
2) Wire up io_pgetevents().
3) Fix perf events on single-PCR sparc64 cpus.
4) Do proper perf event throttling like arm and x86.

The main bit here is fixing how fallback system calls are handled in
the sparc vDSO.
Unfortunately, I fat fingered the commit and some perf debugging hacks
slipped into the vDSO fix, which I revert in the very next commit.

I'm looking at this now.
I cannot reproduce the system crash, but I definitely get the illegal
instruction both with and without using strace. And those system log
message don't show, it must be from some specific config option?
Actually I don't see that "Kernel memory exposure" string anywhere in
the standard upstream kernel.
Running under gdb the process is gone when the SIGILL arrives which
means that a signal wasn't sent but rather the process was forefully
exited by the kernel with SIGILL.
Only two things do that:
1) Failing register window faults (arch/sparc/kernel/process_64.c)
2) Invalid signal frames during signal delivery (arch/sparc/kernel/signal32,
arch/sparc/kernel/signal_64.c)
This is a 64-bit ELF binary so my guess is setup_rt_frame().
I put some debugging in and I guessed wrong:
[ 40.366945] [tweaklib2:428]: fault_in_user_windows() copy failed
Something definitely corrupted the stack and/or frame pointer in this
code.

What this amounts to is actually a very simple program:
davem@salty:/opt/davem/src/GIT/CRASH/kernel-crash-test$ readelf -h tweaklib2
...
Entry point address: 0x1003d0
Entry point 0x1003d0, what's that:
davem@salty:/opt/davem/src/GIT/CRASH/kernel-crash-test$ objdump -d tweaklib2 | grep -A 1 1003d0
00000000001003d0 <SI_PRC_$$__FPC_DYNAMIC_PROC_START>:
1003d0: 81 c3 e0 08 retl
1003d4: 01 00 00 00 nop
An entry point which simply returns. So this program does nothing,
main never gets called, we just return to the dynamic linker code that
jumps to the program's entry point which isn't expected.
So the test case is simply:
davem@salty:/opt/davem/src/GIT/CRASH/kernel-crash-test$ cat test.s
.text
.align 4
.globl _start
_start: retl
nop
davem@salty:/opt/davem/src/GIT/CRASH/kernel-crash-test$ gcc -nostdlib -o test test.s
davem@salty:/opt/davem/src/GIT/CRASH/kernel-crash-test$ ./test
Segmentation fault
davem@salty:/opt/davem/src/GIT/CRASH/kernel-crash-test$
and nothing more.
So what happens when you return from _start like this? It ends up
looping, adjusting the stack pointer up by 48 bytes every iteration.
Eventually we push the stack pointer past the end of the stack mmap
area and crash.
The loop is:
davem@salty:/opt/davem/src/GIT/CRASH/kernel-crash-test$ gdb ./test
...
(gdb) b *0x0000010000000290
Breakpoint 1 at 0x10000000290

And that's how we loop forever.
It should not crash the machine and here with an upstream kernel it does not for me.

Interestingly, we couldn't reproduce the issue on the SPARC-T5 anymore either. It

Please reproduce with a vanilla upstream kernel. I think some of the local
debian kernel patches might be causing this.
Also, wrt. freepascal, as I described in my email, the link of that
binary is causing the NOP _start function to be set as the entry
point.
That can't be right, whatever ends up as the entry point should end up
calling 'main' so that the program actually runs.

It fixes a hard kernel crash under certain loads which we have seen in Debian quite frequently.
Thanks,

Note that it's obviously always easiest for me to just ignore
something like sparc entirely, but on the other hand, particularly for
low-volume trees it's also ok to just say "I don't have anything
pending, here's the link to lore.kernel.org, can you apply that one
patch directly".
(And yes, I prefer lore.kernel.org over marc, although for single
patches it doesn't make much of a difference. For patch series, I find
'b4' so convenient that I definitely want the patch to show up on
lore.kernel.org).
I'll await your pull request or 'I have nothing else, take it from
xyz', this thread is otherwise archived for me as "done".

Sadly, lore does not archive sparclinux@vger.kernel.org, so there
isn't much choice in this case.

sparc: sparc64_defconfig: remove duplicate CONFIGs
After my patch there is CONFIG_ATA defined twice.
Remove the duplicate one.
Same problem for CONFIG_HAPPYMEAL, except I added as builtin for boot
test with NFS.

sparc64: Fix opcode filtering in handling of no fault loads
is_no_fault_exception() has two bugs which were discovered via random
opcode testing with stress-ng. Both are caused by improper filtering
of opcodes.
The first bug can be triggered by a floating point store with a no-fault
ASI, for instance "sta %f0, [%g0] #ASI_PNF", opcode C1A01040.
The code first tests op3[5] (0x1000000), which denotes a floating
point instruction, and then tests op3[2] (0x200000), which denotes a
store instruction. But these bits are not mutually exclusive, and the
above mentioned opcode has both bits set. The intent is to filter out
stores, so the test for stores must be done first in order to have
any effect.
The second bug can be triggered by a floating point load with one of
the invalid ASI values 0x8e or 0x8f, which pass this check in
is_no_fault_exception():
if ((asi & 0xf2) = ASI_PNF)
An example instruction is "ldqa [%l7 + %o7] #ASI 0x8f, %f38",
opcode CF95D1EF. Asi values greater than 0x8b (ASI_SNFL) are fatal
in handle_ldf_stq(), and is_no_fault_exception() must not allow these
invalid asi values to make it that far.
In both of these cases, handle_ldf_stq() reacts by calling
sun4v_data_access_exception() or spitfire_data_access_exception(),
which call is_no_fault_exception() and results in an infinite
recursion.

I did a second pull just moments ago, I'll push it out (along with the

I'm in the process of creating the remainder of vger archives on lore, so it
would have happened anyway, but I'll bump sparclinux up in the queue.
