2.6.7-mm6

ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.7/2.6.7-mm6/

- Added the DVD-RW/CD-RW packet writing patches. These need more work.

- The USB update seems deadlocky. I fixed one bug but it still causes my ia64 test box to lock up on boot. If it goes bad, please revert usb-locking-fix.patch and then revert bk-usb.patch. Retest and send a report to linux-kernel and [email protected].

Changes since 2.6.7-mm5:

Please either use llseek() directly or renamed the thing to vfs_llseek() everywhere. Two names for exactly the same thing are a bad idea.

does this also include patch for the net problems?

no more network slowdown for me :-)

thhere is still network slowdown here, and it really is a kernel issue. i dont understand why, but there is, and i dont understand why it cant be fixed.
also, i still need to run those sysctl lines..
i hope this gets fixed before rc1 :-|

OK, a quick test reveals that my EHCI controller still doesn't work properly but unplugging the USB 2.0 stick doesn't result in a oops anymore...

The message remains the same:

I'm getting this while building for ppc32:

Inconsistent kallsyms data, try setting CONFIG_KALLSYMS_EXTRA_PASS

This didn't happen with -mm5.

The help text for CONFIG_KALLSYMS_EXTRA_PASS says I should report a
bug, and reads like kallsyms is a utility or part of the toolchain; I think it's talking about the kernel feature though, so I guess I'll report it here. I'll keep this tree around in case any more information is needed.

While I'm asking, should I CC Paul Mackerras and/or BenH when reporting build
problems on my Powermac in the -mm tree?

"Bull in pure form is rare; there is usually some contamination by data."
-- William G. Perry Jr.

The kernel's kallsyms feature does, roughly, this:

- generate vmlinux
- generate a list of symbols from it
- turn those symbols into a C array
- generate a new vmlinux which includes that C array

All this assumes that the symbols in the fist and second vmlinux's fall at the same addresses. But for some reason, that doesn't always happen. End
result: the second vmlinux's kallsyms info is wrong. It's not clear why the linker does this.

The third kallsyms pass will generate a list of symbols from the vmlinux+C array and will again generate a vmlinux+C array. It turns out that this is stable.

Run these commands on the tree that needed CONFIG_KALLSYMS_EXTRA_PASS=y (assumes Bourne shell)

for i in 1 2 3; do nm .tmp_kallsyms$i.o > .tmp_mapk$i; nm .tmp_vmlinux$i > .tmp_mapv$i; done tar cjvf /var/tmp/kallsyms.tar.bz2 .tmp_kallsyms* .tmp_vmlinux* .tmp_map*

Send the tarball to me, not the list.

This is a real linker problem on ppc32. The linker automatically adds _SDA_BASE_ and _SDA2_BASE_ symbols, these symbols are not defined in vmlinux.lds.S. The SDA symbols move around as kallsyms data is added between phases 1 and 2. That movement, together with the stem compression (which depends on the immediately previous symbol) means that the compressed symbol table changes size between phases 1 and 2, which it is not supposed to do.

This problem has been there all along. It showed up now because I added a test to verify that the kallsyms data is consistent after phase 2, instead of blindly assuming that it is stable. jhf, can you verify that this patch removes the need for an extra kallsyms pass?

Yes, this builds okay with KALLSYMS_EXTRA_PASS off.

What type are those symbols? I'm surprised they're not 'A' which is already ignored...

Uneventful on alpha, needed a make rpm compilefix Andi's got queued for the next merge on x86-64 and otherwise uneventful there.

OTOH, various things made sparc64 a living Hell that took about 9 hours of solid compile/boot/crash drudgery to carry out bisection search on to find the offending patches.

First, I had to back out bk-input because it has a sysfsification patch that deadlocks sunzilog.c at boot.

Second, I had to back out those scheduler cleanups because it appears that one of those scheduler cleanups deadlocks the system during secondary wakeup.

Third, some naive check for undefined symbols failed to understand the relocation types indicating that a given operand refers to some hard register, which manifest as undefined symbols in ELF executables. A patch to refine its criteria, which I used to build with, follows. rmk and hpa have some other ideas on this undefined symbol issue I've not quite had the opportunity to get a clear statement of yet.

If it could be arranged so that the authors of the bk-input and scheduler patches fix their code prior to merging, I'd be much obliged.

Thanks.

Ok, I think I know what the problem is - it should be an oops rather than a deadlock though - serial drivers are initialized before serio core when serio bus structure is not registered with driver core yet. Could you please try the patch below - I do not have hardware to test it:

It may also help to know that I did bisection search on 2.6.7-mm* that had various contents of bk-input split out; in those, the offending patch was revealed to be input-serio-sysfs-intergration.patch which I think corresponds to:
# ChangeSet

#   2004/06/29 01:28:53-05:00 [email protected] 
#   Input: serio sysfs integration
#   Signed-off-by: Dmitry Torokhov <[email protected]>

or one of the csets nearby in the consolidated bk-input.patch

The only suspicious thing that I see is that sunzilog tries to register its serio ports with spinlock held and interrupts off. I wonder if that is what causing a deadlock. Could you please try applying this patch on top of the changes to the drivers/Makefile that I sent earlier.

Dmitry

This suspicion is correct. It boots normally with the patch you posted to do that registration outside the interrupts-off critical section applied. Bootlog below.

Thanks.

Great! I am still somewhat confused why it started locking up with sysfs patch - even before sunzilog was calling serio_register_port with interrupts off and serio core was downing it's serio_sem as the very first thing. Since at the time sunzilog registers its ports no serio drivers have been registered yet, effectively the only change introduced by sysfs patch is the call to device_register which takes bus' subsystem rwsem and there really should not be any congestion.

Maybe rwsems can not be touched with interrupts off? Sparc only? Everywhere? (I know that you should not normally call functions that may sleep with interrupts off).

Dmitry

CONFIG_PREEMPT enables this to be warned on appropriately. It should basically never happen unless it's a down_trylock() etc.

-- wli

Shall I add this to my BK then?

I was planning on pushing some updates to you later tonight, but if you want you can just apply that patch. The change to Makefile is also needed.

Dmitry

I can wait for the pull. ;)

Vojtech Pavlik

I converted that to a non-fatal warning due to the same problem on sparc64.

Here's the current patch against -linus. I think I'll drop it. Could you please work with rmk to come up with a final version?

Andrew, Russell posted to us in private email an objdump based check that didn't trigger for the register declaration case.

He seems not to have cc:'d me. Apparently *UND* isn't always the fourth field so he did objdump --syms vmlinux | grep '^[^R][^E][^G].*\*UND\*' instead of the awk expression I brewed up.

-- wli

Well, it seems it doesn't work for the .tmp_vmlinux1 object:

$ arm-linux-objdump --syms .tmp_vmlinux1 | egrep '^([^R]|R[^E]|RE[^G]).*\*UND\*'
00000000  w      *UND*  00000000 kallsyms_addresses

Seems we can't win either way. ;(

#sched-no-balance-clone.patch #sched-remove-balance-clone.patch #sched-fork-hotplug-cleanuppatch.patch

I have it isolated down to the sched-clean-init-idle.patch and sched-clean-fork.patch. sched-clean-init-idle.patch fails to build without the second of those two applied, so I didn't do any work to narrow it down further.

-- wli

One thing to note is that we don't currently call the wake_up_forked_process() thing in our SMP idle bootup dispatcher in arch/sparc64/kernel/smp.c

Perhaps that is somehow related to the problems. In that case the culprit would be the first patch, sched-clean-init-idle.patch

See arch/sparc64/kernel/smp.c:smp_boot_one_cpu() for details. When we start a cpu, by calling prom_startcpu(), the cpu jumps from the firmware into arch/sparc64/kernel/trampoline.S

There, the cpu is initialized (just like it is for the boot cpu in arch/sparc64/kernel/head.S), the current_thread_info() (%g6) and 'current' (%g4) registers are initialized and the cpu jumps into smp_callin(). smp_callin() returns when it is safe to do so, which is when it's cpu bit is set in smp_commenced_mask. When that occurs, it's cpu bit is set in cpu_online_map and then it jumps right into cpu_idle().

Hope this helps.

Yes, I missed sparc64 due to the lack of wake_up_forked_process. Dang.

Well, what used to happen is that wake_up_forked_process would put the idle task on the runqueue like a regular process, then init_idle would take it off again.

However after the patch, init_idle simply does all the work itself, and doesn't have to deal with removal from the runqueue. Now sparc64 uses "kernel_thread" to clone its idle tasks, which *does* put the process onto the runqueue. init_idle then also makes it the idle task. This is probably why it blows up.

I guess another small function to remove the task from the runqueue before calling init_idle for those arches that want it would be the way to go.

Sorry, this is my fault. Got to run now, but I'll send a patch to try in a few hours if someone hasn't already.

the patch below should solve this. Is it safe on sparc to do a fork_by_hand() like this?

If the regs are garbage, copy_thread() will explode as it tries to interpret the stack pointer in that regs value.

The parent's regs (stored in current_thread_info() at trap time, and also needed by copy_thread() processing) will also be garbage since we're avoiding the fork syscall trap.

In short, this won't work :)

This is why I use kernel_thread(). Why is that so bad?

We could make CLONE_IDLETASK clones not do the wakeup?

Ingo? I guess an alternative is to have the arch explicitly make a call to dequeue it.

This is all just context switching and bootstrap ordering, but I really have other vastly more urgent things to do at the moment than cleanups. Please present a self-contained fixed-up init_idle() cleanup for me to testboot. Even the one in -mm is not so, as it depends on later patches to even compile.

-- wli

If you could help that would be great. You needn't do anything other than test. The patch sort of enables run cloned thread last which allows us to remove balance on clone, which is important. For me.

The patch I just sent (which is on top of -mm6) should hopefully work... if you feel like testing a solution that may still get vetoed by Ingo.

Also, what compile errors are you getting? i386 seems to compile kernel/ fine with only the first sched- patch applied.

looks fine to me. It somewhat reduces the utility of copy_process() [which we primarily introduced to enable wakeup-less SMP bootstrapping], but i cannot see any good solution besides moving copy_thread() out of copy_process(), which is unsafe. (ptrace could potentially access the new task before copy_thread() is done, etc.) So i'd go for the simple solution of CLONE_IDLETASK not doing a wakeup.

Ingo

"atop -mm6" is not what I'd call a self-contained patch. I'm relatively irritated about the approach to (or perhaps even avoidance of) testing in isolation going on here. I have other things I very urgently need to do, and I doubt whatever I get for doing your homework for you will pay for screwing up public presentations. I have had enough trouble in general isolating causes of failures, so please prep this properly.

-- wli

I'll take that as a no.

I don't really follow you.

And you still haven't told me what compile errors you are getting. I don't have an evironment to build or test a sparc64 kernel.

--target=sparc64-linux-elf should get you out of the glibc hassles.

-- wli

On my test system with Via chipset, no ACPI everything (mouse and storage device) works fine.

On my main system with Via chipset and ACPI, my USB mouse does not work at all.

Reverting usb-locking-fix.patch and bk-usb.patch makes it work again.

Jesse Stockall <[email protected]>

Now that John has accepted the LANANA device number request, can you please merge this into the BK tree? It fixes the panics we were seeing with the 8250 driver and also includes early printk support, which is really nice for debugging early boot problems (and, as luck would have it, the ia64 tree has one at the moment).

Thanks,
Jesse
