[PATCH 1/2] kernel/{sched,smp}.c: fix static decl prior to struct declaration

[Jeff Garzik]

According to C99 6.9.2p3, any declaration "static struct foo my_foo;"
must follow the definition of struct foo.

Apparently, gcc's lack of warning is a bug.

[RFC PATCH 2/2] kernel/sched.c: VLA in middle of struct

[Jeff Garzik]

The semantics for variable-length arrays __in the middle of structs__
are quite muddy, and a case in sched.c presents an interesting case,
as the preceding code comment indicates:

	/*
	 * The cpus mask in sched_group and sched_domain hangs off
	 the end.  * FIXME: use cpumask_var_t or dynamic percpu alloc
	 to avoid * wasting space for nr_cpu_ids < CONFIG_NR_CPUS.  */
	struct static_sched_group {
		struct sched_group sg; DECLARE_BITMAP(cpus,
		CONFIG_NR_CPUS);
	};

	struct static_sched_domain {
		struct sched_domain sd; DECLARE_BITMAP(span,
		CONFIG_NR_CPUS);
	};

Both sched_group and sched_domain have the following trailing struct
member:

	unsigned long cpumask[];

So this change is intended largely to spawn a discussion, because
I'm not sure this VLA-in-middle-of-struct behavior is guaranteed to
always behave as expected?

Maybe a C expert can say whether cpumask[0] is better than cpumask[],
or have other comments?

Obviously not to be applied...

This block has a visible imbalance of preprocessor directives - 
there's a #else you moved, without moving the outermost #ifdef. My 
guess is that this will go down in a fireball with 
CONFIG_GROUP_SCHED disabled?

It seems you are correct, I missed it in my 'allmodconfig' and 'jeffs hw 
config' builds.

Are you fixing this up, or should I regen the patch?

This bit of the code is a bit temporary, with a half-done cpumask 
conversion ...

I'm not convinced at all that this code wants to be converted to 
cpuvar_t. These are all either statically percpu or dynamically 
allocated structures, so we wont allocate NR_CPUS of them. So i'd 
lean towards embedding a full struct cpumask and that's it.

That cpumask[] should probably be cpumask[0], to document the 
aliasing to ->span and ->cpus properly.

Rusty, what do you think?

Please resend it. That area of the code is a bit of an #ifdef maze, 
hard to move around. (And i'd rather let you mess it up than mess it 
up myself - then i can blame it on you and bounce it back to you for 
fixing ;-)

Also, a style cleanup there might help a bit: adding a bit more 
geometric structure to the #ifdefs there might make the hierarchy 
stand out a bit more:

# ifdef CONFIG_RT_GROUP_SCHED
static DEFINE_PER_CPU(struct sched_rt_entity, init_sched_rt_entity);
static DEFINE_PER_CPU(struct rt_rq, init_rt_rq) ____cacheline_aligned_in_smp;
# endif /* CONFIG_RT_GROUP_SCHED */
#else /* !CONFIG_USER_SCHED */
# define root_task_group init_task_group
#endif /* CONFIG_USER_SCHED */

in such a lineup it's more apparent at a glance when a piece of code 
gets snatched in an incomplete way.

Thanks,

	Ingo

Yeah, it's kinda nasty.  Generally, sched_group is dynamically allocated,
so we just allocate sizeof(struct sched_group) + size of nr_cpu_ids bits.

These ones are static, and it was easier to put this hack in than make them 
dynamic.  There's nothing wrong with it, until we really want NR_CPUS ==
bignum, or we want to get rid of NR_CPUS altogether for 
CONFIG_CPUMASKS_OFFSTACK (which would be very clean, but not clearly 
worthwhile).

But more importantly, my comment is obviously unclear, since your patch shows 
you didn't understand the purpose of the field: The cpus bitmap *is* the sg-

[0] is a gcc extension, but it should be equivalent.

Nothing wrong with it, except

- C99 only defines variable-length automatic arrays
- VLA in the middle of a struct are difficult to optimize
- gcc's VLA handling WILL change, as gcc docs state
- other compilers -- and sparse -- puke all over VLAs, making
  static analysis impossible for all code with this weirdism

I guess you missed the

I dont think Jeff misunderstood this code (hey, he found it! :), his 
patch is a demonstration of why this code is a problem: a seemingly 
innocious invariant modification (his patch) kills the kernel dead.

It's a visual helper: it matches up with how we do these 'zero size 
array means dynamic structure continuation' tricks generally.

I first mis-parsed the code for a second when seeing cpumask[]. 
cpumask[0] stands out like a sore thumb. And we dont read comments 
anyway ;-)

Jeff, i suspect you found this because you are working on something 
rather interesting? :) If yes, would it help your project if we did 
the cpumask[0] cleanup and pushed it upstream immediately?

kernel/{sched, smp}.c: fix static decl prior to struct declaration

According to C99 6.9.2p3, any declaration "static struct foo my_foo;"
must follow the definition of struct foo.

Apparently, gcc's lack of warning is a bug.

v2:
  - fix ifdef imbalance, by moving entire USER_SCHED code block
  - indent cpp directives, to indicate nesting

Fixed and resent.

What a rat's nest of ifdefs!  root_task_group is outside 
CONFIG_USER_SCHED, and so I kept that property in patch v3.

However, its definition in kernel/sched.h is conditional on 
CONFIG_USER_SCHED, even though root_task_group_empty() may exist outside 
of CONFIG_USER_SCHED, and root_task_group is referenced vi
CONFIG_FAIR_GROUP_SCHED || CONFIG_RT_GROUP_SCHED.

Starting to wish I had never patched this code in the first place (that 
barb is directed at the code, not you...)

Yeah, it was intended to spark debate...  definitely not to be applied 
(hence "NOT-signed-off-by", among other hints).

I think cpumask[0] would be more clear and consistent with the rest of 
the kernel.

But unfortunately for the twin projects of (a) static analysis and 
checking with 'sparse', and (b) compiling under another compiler, 
VLA-in-middle-of-struct is a killer in either case.

How would you fix it? People dont like the idea of unconditional 
group scheduler, so we cannot remove the variability really.

kernel/{sched, smp}.c: fix static decl prior to struct declaration

According to C99 6.9.2p3, any declaration "static struct foo my_foo;"
must follow the definition of struct foo.

Apparently, gcc's lack of warning is a bug.

v3:
  - fix compile breakage WRT root_task_group.
v2:
  - fix ifdef imbalance, by moving entire USER_SCHED code block
  - indent cpp directives, to indicate nesting

[ Impact: cleanup, fix for Sparse ]

i somehow have the feeling that this commit is not going to be the 
favorite one you'll tell your grandchildren about :-/

-tip testing found:

kernel/sched.c:659: error: redefinition of ‘root_task_group_empty’
kernel/sched.c:371: error: previous definition of ‘root_task_group_empty’ was here
kernel/sched.c:661: error: ‘init_task_group’ undeclared (first use in this function)
kernel/sched.c:661: error: (Each undeclared identifier is reported only once
kernel/sched.c:661: error: for each function it appears in.)

Find the config below.

Thanks,

	Ingo

Putting the VLA at the end of the struct would be a huge help, yes.

For example, struct sched_group and struct sched_domain are OK as-is 
(though "[0]" would be preferred).

It is the definition of struct static_sched_group and struct 
static_sched_domain that creates the problem, because with the bitmap 
following cpumask[] and span[], the VLA is no longer at the end of the 
struct.

VLA-in-the-middle raises the complexity required of the compiler quite a 
bit.  As a result, VLA-in-middle is not implemented in sparse or clang 
(LLVM's C front-end and static analyzer).

feel free to send patches for this - i dont have those build modes 
to test that it's sufficient. I'd suggest to go the simplest path: 
remove all the vla aliasing tricks: just make struct sched_domain 
use a plain struct cpumask and eliminate static_sched_domain 
altogether.

The memory overhead is marginal as most of our sched domains are 
static allocated (and full size) anyway.

Jeff, you seem confused.  In my copy of the standard, you'd know this is called 
a "flexible array member"; it's not a variable length array.  The only GCC 
specific issue I can find here is that you're not normally allowed to embed 
structs with them in another struct (according to the gcc docs; I can't 
actually find this clearly stated in the standard).

Terribly sorry, I was too polite.  Your patch was so broken it didn't make any 
sense.  At all.

Anyway, since [] is C99, I thought it preferable to [0] which is a gcc 
extension.  However, if C99 is really so braindead as to disallow this fairly 
standard trick, so I'm happy to go with the gcc extension.[1]

Thanks,
Rusty.
[1] Well, not happy.  But y'know...

6.7.2.1p2.  It's a separate issue from revolting gcc extension that *do*
allow VLA-in-the-middle-of-struct.  And I mean real VLA, not flex array
member :-/

No.  There's a standard way to do that in C99; you can put a struct with
that thing into a union.  So correct way to force enought storage for
such an object is

union {
	struct has_flex_array_member foo;
	char [how_much_space_do_I_want];
} bar;

Unions with overlapping members are fine.  Structures are not.

Ah, thanks for the clue.

How's this:

sched: avoid flexible array member inside struct (gcc extension)

struct sched_group and struct sched_domain end in 'unsigned long
cpumask[]' which Jeff Garzik notes is not legal to place inside
another struct.  It upsets sparse and clang (LLVM's C front end).

Al Viro pointed out that a union is the Right Way to do this.

struct sched_group and struct sched_domain end in 'unsigned long
cpumask[]' which Jeff Garzik notes is not legal C to place inside
another struct.  It upsets sparse and clang (LLVM's C front end).

Al Viro pointed out that a union is the Right Way to do this.
