2.6.12-rc5-mm1

ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.12-rc5/2.6.12-rc5-mm1/

- Added Oracle's clustering filesystem driver, via git-ocfs.

OCFS2, a shared disk cluster file system. See Documentation/filesystems/ocfs2.txt Additionally a users guide is available at:
http://oss.oracle.com/projects/ocfs2-tools/dist/documentation/users_guide.txt

- New Xtensa architecture: Tensilica Xtensa CPU series.

- Added the Red Hat distributed lock manager for people to look at.

- Various new git trees. The remaining holdouts are:

bk-acpi.patch
bk-drm.patch
bk-drm-via.patch
bk-input.patch
bk-nfs.patch
bk-watchdog.patch

- The CPU scheduler is probably busted on the less-common architectures. For now, those architectures will need to emulate sched-remove-set_tsk_need_resched-from-init_idle-v2-ia64-fix.patch

- Added the s390 team's execute-in-place driver. Not sure that I like all the code duplication in this though.

- Again, if there are patches in here which you think should be merged in 2.6.12, please point them out to me.

- CPU scheduler udpates, kexec/kdump updates, i2o updates, v4l updates, etc.

Hi Andrew,

It looks like dlm assumes that CONFIG_DLM_DEBUG is set. The attached patch fixes this.

Hi Andrew,

This patch updates all the device attribute callbacks that weren't updated with the new parameter, I guess because they weren't in Greg's tree (including drivers/pcmcia/ds.c). Without the patch these callbacks are probably broken (and generate a warning along the lines of "assignment from incompatible pointer type").

Please see http://lkml.org/lkml/2005/5/19/40 for the scripts I used to update the attributes automatically.

Thanks,
Yani

I'd say the following patches of mine might are candidates :

atm-nicstar-remove-a-bunch-of-pointless-casts-of-null.patch cosmetic-fixes-for-example-programs-in-documentation-cdrom-sbpcd.patch dont-do-pointless-null-checks-and-casts-before-kfree.patch get-rid-of-redundant-null-checks-before-kfree-in-arch-i386.patch kfree-cleanups-for-drivers-firmware.patch kfree-cleanups-in-ixjc.patch remove-pointless-null-check-before-kfree-in-sony535c.patch remove-redundant-null-check-before-before-kfree-in.patch remove-redundant-null-checks-before-kfree-in-sound-and.patch streamline-preempt_count-type-across-archs.patch preempt_count-is-int-remove-cast-and-dont-assign-to.patch

They are all quite simple and have not been the cause of any trouble in -mm, so we might as well get them merged.

I get the following when trying to build rc5-mm1:

make[1]: *** [arch/i386/kernel/setup.o] Error 1
make[1]: *** Waiting for unfinished jobs....

Looks like when #ifdef CONFIG_ACPI was added to include/linux/acpi.h it broke things b/c acpi_sci_flags is needed for CONFIG_ACPI_BOOT, which depends on X86_HT || ACPI. Thus, you can have ACPI=n, and X86_HT=y & ACPI_BOOT=y and it won't build. This patch at least gets it to build for me...

Me too. As beep-media-player ends playing a mp3 track, oops ! Decoded below, for if it gives additional info:

Warning: You did not tell me where to find symbol information. I will assume that the log matches the kernel and modules that are running right now and I'll use the default options above for symbol resolution. If the current kernel and/or modules do not match the log, you can get more accurate output by telling me the kernel version and where to find map, modules, ksyms etc. ksymoops -h explains the options.

OK, thanks. I guess we can set this problem aside for now, as this bug isn't present in 2.6.12-rc5 (correct?).

I assume the problem is due to one of the ASLA patches in rc5-mm1, but it's possible that it lies elsewhere. It would be great if someone could fire up quilt and do a binary search...

To summarise, we have three people (one Opteron, one x86, one unknown-x86_64) reporting this:

2.6.12-rc5-mm1 includes Andrea's seccomp-disable-tsc patch, which I believe is broken on SMP. In process.c we find:

/*
+ * This function selects if the context switch from prev to next
+ * has to tweak the TSC disable bit in the cr4.
+ */
+static void disable_tsc(struct thread_info *prev,
+ struct thread_info *next)
+{
+ if (unlikely(has_secure_computing(prev) ||
+ has_secure_computing(next))) {
+ /* slow path here */
+ if (has_secure_computing(prev) &&
+ !has_secure_computing(next)) {
+ clear_in_cr4(X86_CR4_TSD);
+ } else if (!has_secure_computing(prev) &&
+ has_secure_computing(next))
+ set_in_cr4(X86_CR4_TSD);
+ }
+}

which it calls from __switch_to().

The problem is that {set,clear}_in_cr4() both update a single global mmu_cr4_features variable, which is asynchronously written to all CPUs by {,__}flush_tlb_all(). Hence, the CR4.TSD setting is at best probabilistic.

I spotted this because perfctr used to flip CR4.PCE in __switch_to() ages ago, but I had to abandon that when kernel 2.3.40 changed to the current scheme with a global mmu_cr4_features. (Another reason was that CR4 writes were and still are very slow.)

/Mikael

You're right. This won't destabilize the kernel (and it couldn't trigger in my testing) but it may lead to the tsc to be erroneously disabled on a non-seccomp task, after a change_page_attr (i.e. insmod) or similar events using flush_tlb_all (like rmmod). I didn't notice this race condition sorry (I now recall why we overwrite the cr4 flag in the global tlb flush: just to flush the global pagetables, since vmalloc uses global pagetables too).

Speed is not an issue, cr4 would never be tweaked unless you use seccomp, the cr4 flip is in an extreme slow path.

I think there are two ways to solve this race:

1) why don't we read the cr4 from the cpu? would movl %%cr4, %%eax generate a general protection fault? Can the cr4 be read in ring 0? Why to read it from memory if we've that information in the cpu already?
2) If there's a good reason to read if from memory, then what about making the mmu_cr4_features per-cpu? That way would solve the problem too.

Both solutions relay on the fact that the pagetable flush cannot happen from irqs, so as long as set/clear_in_cr4 is never called from irq (like in switch_to with this patch), no locking would be required. If the pagetable flush can be called from irqs (or alternatively if the set/clear_in_cr4 can be called from irqs) then we'd need to use test_and_set/clear_bit instead of normal C code despite the structure being per-cpu, or despite reading the data from the cpu instead of reading it from memory. In theory we could add a BUG_ON(in_interrupt()) to both, since both set/clear_in_cr4 and the flush_tlb_all aren't fast paths (probably it worth it just in case).

Comments welcome, thanks!

Yes the kernel can read cr4. I believe the best solution is to modify __flush_tlb_global() to read cr4's current value and mix it in when toggling CR4.PGE and uploading mmu_cr4_features.
(But please make it conditional on CONFIG_SECCOMP.)

The code called from __switch_to() would have to set or clear cr4 locally only. That's easy using write_cr4() and read_cr4().

/Mikael

Why should it be conditional? Isn't it faster to read it from the cpu itself instead of reading it from slow ram? That info is cold in the cache when the global tlb flush is invoked, while it's always in hot in the cpu. Perhaps the cpu is dogslow at reading cr4 or what?

Note that the whole mmu_cr4 thing seems pretty flawed if used at runtime, that's only necessary to initialize new cpus (head.S). So basically at runtime nobody should read or write to mmu_cr4_features global variable.

Agreed.

Here an update that passed successfully basic testing verifying task gets killed with sig11 if rdtsc is used in seccomp mode on x86-64 (i686 still untested but fully symmetric).

From: Andrea Arcangeli <[email protected]>

I believe at least for seccomp it's worth to turn off the tsc, not just for HT but for the L2 cache too. So it's up to you, either you turn it off completely (which isn't very nice IMHO) or I recommend to apply this below patch.

This has been tested successfully on x86-64 against current cogito repository (i686 compiles so I didn't bother testing ;). People selling the cpu through cpushare may appreciate this bit for a peace of mind.

There's no way to get any timing info anymore with this applied (gettimeofday is forbidden of course). The seccomp environment is completely deterministic so it can't be allowed to get timing info, it has to be deterministic so in the future I can enable a computing mode that does a parallel computing for each task with server side transparent checkpointing and verification that the output is the same from all the 2/3 seller computers for each task, without the buyer even noticing (for now the verification is left to the buyer client side and there's no checkpointing, since that would require more kernel changes to track the dirty bits but it'll be easy to extend once the basic mode is finished).

Eliminating a cold-cache read of the cr4 global variable will save one cacheline during the tlb flush while making the code per-cpu-safe at the same time. Thanks to Mikael Pettersson for noticing the tlb flush wasn't per-cpu-safe.

The global tlb flush can run from irq (IPI calling do_flush_tlb_all) but it'll be transparent to the switch_to code since the IPI won't make any change to the cr4 contents from the point of view of the interrupted code and since it's now all per-cpu stuff, it will not race. So no need to disable irqs in switch_to slow path.

I noticed this has another copy of all the backwards compatibility syscalls in its arch/*/kernel/syscall.c file. This doesn't make sense for a new architecture added to the tree.

Chris, are there any existing binaries that rely on your implementations of old_mmap, sys_fork, sys_vfork, sys_olduname or sys_ipc and need to work with future kernels? Otherwise, you should probably drop these. For sys_ipc, you would need to add the subcalls directly to the table, like parisc does.

	Arnd <><

We should do that either way. If people have existing binaries relying on broken thing before submitting ports for review it's their fault.

Hmm, xtensa is now in -rc1, with the obsolete syscalls still in there, so I guess this about the last chance to correct the ABI. Applying the patch obviously breaks all sorts of user space binaries and probably also requires the appropriate changes to be made to libc.

On the other hand, if a decision is made to keep the broken interface, it should at least be a conscious one instead of an oversight.

I have to admit, the -rc1 caught me a bit by surprise; I have a few patches pending that I want to send out today.

The question is, if we had to break glibc compatibility, shouldn't we use the opportunity to clean-up the syscall list? It was copied from MIPS and, thus, has inherited a lot of legacy from there. As a new architecture, maybe we should even go as far as removing all ni-syscalls and start fresh?

I will try out your patch and see if there are any obvious problems.

Thanks,
~Chris

Yes, that should be done for a new architecture. Unfortunately very few people actually care. Btw, what libcs do you have ported to xtensa?

If you can cope with having the syscalls renumbered then yes, that would be good.

I tried to make the patch in a way that at least the majority of binaries built against the reduced set of syscalls would still work with old kernels, though typically not the other way round.

If you don't mind reordering the syscalls, you could even take this a few steps further:

- remove all 32 bit file syscalls that have a 64 bit replacement (e.g. pread, lseek)
- remove all legacy signal handling in favor of rt_sig*
- remove struct stat and rename struct stat64 to stat
- remove wait4 in favor of waitid
- use utimes instead of utime
- use normal calling conventions for sys_pipe
- split sys_xtensa into separate sys_atomic_{set,exg_add,add,cmp_swp}
- if you are still motivated, make this setup the default for an empty arch/*/kernel/syscalls.c and no __ARCH_WANT_FOO definitions to make it easier to explain to the next architecture port maintainer.

Not commenting on your specific patch here, just the bit about what the point is of using explicitly signed chars. C doesn't define if chars are signed or unsigned by default, that's up to the implementation. So if it matters to you that chars should be either signed or unsigned you have to explicitly specify them as signed or unsigned.
I haven't read the code you change, not the patch, so I don't know if it's an issue, but there are certainly arguments for explicitly specifying signed char or unsigned char in C code.

Jesper Juhl

Well, to my surprize, linux-ppc uses UNSIGNED chars by default. It has amazed me but it's a fact. Let's compile this little program on tux-ppc :

$ cat ints.c
#include <stdio.h>

main()

{
        int i1, i2;
        char c1, c2;

        c1 = i1 = 0;

        c1--; c2 = c1;
        i1--; i2 = i1;

        c2 &= ~(c2 >> 1);
        i2 &= ~(i2 >> 1);

        if (c1 < 0) printf("c1<0: %d\n", c1); else printf("c1>=0: %d\n",c1);
        if (c2 < 0) printf("c2<0: %d\n", c2); else printf("c2>=0: %d\n",c2);
        if (i1 < 0) printf("i1<0: %d\n", i1); else printf("i1>=0: %d\n",i1);
        if (i2 < 0) printf("i2<0: %d\n", i2); else printf("i2>=0: %d\n",i2);
}

c2>=0: 128
i1<0: -1

=> As you can see, 0 - 1 returns 255 as a char, and -1 & ~(-1 >> 1) = 128 ! ints are OK BTW. I'm gonna change some of my code to fix this because relying on signed chars to to detect unassigned values (-1) is wrong !

Oh and BTW, here's the result on x86 :

$ gcc-3.3 -o ints ints.c
$ ./ints
c1<0: -1
c2>=0: 0
i1<0: -1
i2>=0: 0

Cheers,
Willy

The signedness of 'char' is never certain between compilers. There are x86 C compilers that implemented 'char' as unsigned, others as signed, and others that offered a compile switch to do either way if the default didn't work with the code being compiled.

When it matters, just be explicit :)

It is not a problem about chars signedness (i suppose it depends on processor ops with bytes, if it uses them as signed or unsiged, do sign extensions and so on...).

The problem is that a function expecting a 'char' is given a 'signed char' or 'unsigned char'. Just type the arguments the way they are expected. On PPC, 'char' argument will be unsigned and 'char' parameter also. What does strcpy() internally doesn't matter. Fine.

The gcc 2.95 is deprecated, so I think this is not a real problem.

Matthias-Christian Ott

Who said gcc 2.95 was deprecated? The documentation in the kernel even lists gcc 2.95 as the recommended compiler.

gcc 2.95 is definitely still supported, and (at least on i386) code that doesn't compile with gcc 2.95 is not suitable for Linus' tree.

Hi,

The attached patch solves the problem by adding a '0' to the array declaration. I don't know if this is ethically correct, but I saw it in some v4l-code, so I assume it is.

Thanks for reporting,
Patrick.

Hi,

Only with gcc-2.95 and it worked...

I guess I should have tried it with gcc-3.x before sending, sorry.

Nope. There's a bug in gcc-2.95.x macro expansion, and here it bites us in atm_printk():

printk(level "ATM dev %d: " format , (instance)->atm_dev->number, ## arg)

the workaround is to add a space before that final comma:

Yes, this fixes the problem.

2. ASUS ACPI is not working anymore (this since some -mm ago), modprobe asus_acpi fails to load saying a generic "No such device"

Note that both 1. and 2. work on plain 2.6.12-rc5, and 1. was fine in 2.6.12-rc4-mm*

Attached lspci-v and .config

Bye.

This patch makes i2o_parm_issue static resulting in the following compile error in the static case (the modular case doesn't give a compile error, but EXPORT_SYMBOL'ing a static functions is equally wrong):

<-- snip -->

...

drivers/built-in.o(.text+0x691d55): In function `i2o_cfg_parms':
: undefined reference to `i2o_parm_issue'
make: *** [.tmp_vmlinux1] Error 1

<-- snip -->

This patch turns i2o_parm_issue back into a global function.
