Subject: [Build Faliure] 2.6.25-rc5-mm1 build fails

Hi Andrew,

The 2.6.25-rc5-mm1 kernel build fails with allyesconfig

LD .tmp_vmlinux1
fs/built-in.o: In function `reiser4_debugtrap':
/root/kernels/linux-2.6.25-rc5/fs/reiser4/debug.c:295: undefined reference to `breakpoint'
make: *** [.tmp_vmlinux1] Error 1

This build failure has been introduced by reiser4.patch, i think the
breakpoint() have been used instead of kgdb_breakpoint().

Yes, it has been doing this for a while. But apparently it doesn't happen
for Bart with just his patch queue. <slightlypeeved>If your subssytem
fails in my tree, that doesn't automatically make it my
problem</slightlypeeved>

I'll take a look, see what went wrong.

Caused by ide-mm-ide-add-ide-4drives-host-driver-take-3.patch. Applying
that patch alone to current mainline causes the above error after i386
`make allmodconfig'.

Just exporting the symbol doesn't fix it, so something funny is going on.

probe_4drives should not be initialised to zero.

probe_4drives should not be declared extern in drivers/ide/ide.c - please
declare it in a header which is included by the definition site and by all
users.

No need to peeve - it is not like I forget about the problem or ignored it
after I got your _first_ mail.

I just couldn't reproduce it here so instead I has been working on making
_all_ probe_* variables static (it should make the problem vanish alongside
some other nice improvements).

Thanks,
Bart

I was aware of the warnings and this was only temporary (it is already fixed
by to-be-posted-today patch which removes deprecated "idex=" kernel parameters
and makes _all_ probe_* variables static).

Thanks,
Bart

whee.

Things are going much much more smoothly now than they were in 2.6.24-rcX
and 2.6.23-rcX. Tree integration problems are negligible and build errors
are far fewer and runtime problems seem to be less too. Fingers crossed.

I guess this is due to a combinaton of

a) linux-next

b) intensive whining and

c) extra care which maintainers are taking (due to a) and b))

I suspect that fewer people are testing linux-next and -mm nowadays. We
should encourage them to do so, although given the general
trainwreckishness of current mainline, this isn't really where our effort
should be expended.

Would anyone have objection to have PARAVIRT depend on PCI, since the
vsmp paravirt bits depend on PCI cfg space to determine if the system is
vsmp? If not, this patch would suffice.

Glauber?

Thanks,

Make PARAVIRT depend on PCI.

vSMP PARAVIRT ops probe the pci config space to determine if the
system is indeed a ScaleMP vSMP box. Hence, depend on PCI to enable
PARAVIRT.

NAK. Xen doesn't depend on PCI at all. Why not make VSMP depend on
PCI? Then you could put something like:

#ifdef CONFIG_X86_VSMP
extern void vsmp_init(void);
extern int is_vsmp_box(void);
#else
static inline void vsmp_init(void)
{
}

static inline int is_vsmp_box(void)
{
return 0;
}
#endif

in an appropriate header.

Hm, looks like arch/x86/kernel/Makefile should be

obj-$(CONFIG_X86_VSMP) += vsmp_64.o

rather than making it depend directly on CONFIG_PARAVIRT.

hm, that's not a good idea - there's nothing in lguest, Xen and even KVM
that is inherently tied to PCI.

Beats me. Maybe we're still enabling interrupts too early. But the new
semaphore code got fixed (didn't it?)

On the 7th, according to my records. Easy to check -- look in
kernel/semaphore.c and see whether down() is using spin_lock_irqsave
(good) or spin_lock_irq (bad).

I am having trouble booting rc5-mm1 on my x86_64. (ppc64 boots & works
fine). Seems to be a networking issues (hangs on boot). Here are the
messages on the console (not really useful to me).

On a good kernel (rc5), the next set of messages would be ..

IP route cache hash table entries: 262144 (order: 9, 2097152 bytes)
TCP established hash table entries: 524288 (order: 11, 8388608 bytes)

Dquot-cache hash table entries: 512 (order 0, 4096 bytes)
msgmni has been set to 13864 for ipc namespace ffffffff806903a0
..

Sorry for not being really useful here. But would like to
know if its a known issue ? Or should I start bisecting ?

Thanks,
Badari

went away when netconsole was disabled. I think netconsole is still
busted.

OK, so it looks like it died during networking initialisation.

Could you please add initcall_debug to the boot command line so we can see

pressing the 'Alt' key let the system continue until the network hang.

-> same hang, no reaction to SysRq.

What looks suspicious: The call to pcie_aspm_init is just before the
temporary hang. When I used make oldconfig to upgrade the .config from
2.6.25-rc3-mm1 to -rc5-mm1 I activated the new option CONFIG_PCIEASPM.

I will try with CONFIG_PCIEASPM_DEBUG added and completely without this option.

Won't lockdep/irqtrace warn if that happens ? You don't yet have the
lockdep patches for ppc64 (I'm still trying to find out why they break
iSeries) but it should warn of such a spurrious IRQ enable on other
archs too... At least, from a quick look at the code, it -seems- that it
does have such a test.

Cheers,
Ben.

Yes it does work, thanks.

But it does hang on boot. I'm unable to get any information with
Sysrq-keys. I'll start a bisection to narrow this problem.

I attached my .config FWIW.

The spin_lock_irq in __down_common is correct. We're going to schedule(),
so we spin_unlock_irq() to save us passing the flags into the helper
function. If we had interrupts disabled on entry, there's an Aieee
for that.

Works fine here with those very same settings, except for a BUG message
and a warning I'll report separately and which don't seem to have any
serious consequences. This is a 32 bit build on a rather ordinary
Pentium D/Intel motherboard/openSUSE 10.3 workstation.

I thought we already fixed this, actually. Maybe we just talked about it

Hi All,

Sorry for all the noise made :-(, something wrong in the test setup from my end,
the kernel was 2.6.25-rc3-mm1 not 2.6.25-rc5-mm1. This bug is not seen in the
2.6.25-rc5-mm1 kernel.

Yes, I was hitting the text_poke() oops with 2.6.25-rc3-mm1 but not with
2.6.25-rc5-mm1.

This _might_ have been due to a snafu in git-x86: it had a [patch 2/2] from
Mathieu but was missing the needed [patch 1/2]. But I don't know if this
was the cause and I don't know whether 2.6.25-rc3-mm1's git-x86 had the
same problem.

Hi Andrew,

Finally narrowed down the problem to git-sched.patch in rc5-mm1.
I am going to try which individual patch in that git caused my
amd64 boot hang.

Peter, Ingo - here are the boot messages on the console. Any ideas ?
config file attached.

Thanks,

Further narrowed it down to following patch in git-sched.patch.
When I back out this patch from rc5-mm1, my amd64 box boots fine.

commit 60befbc1c0b6d141c9c26e61ddd303aedd1e7396
Author: Guillaume Chazarain <[email protected]>
Date: Mon Mar 10 08:16:41 2008 +0100

sched: make sure jiffies is up to date before calling
__update_rq_clock()

Now that __update_rq_clock() uses jiffies to detect clock overflows,
make sure jiffies are up to date before touch_softlockup_watchdog().

Removed a touch_softlockup_watchdog() call becoming redundant with
the
added tick_nohz_update_jiffies().

I didn't know this patch could prevent booting, but anyway it should
have been removed a long time ago:

I don't know whats happening either, but my debug shows that
tick_nohz_update_jiffies() always returns due to following
check without calling touch_softlockup_watchdog().

if (!ts->tick_stopped)
return;

BTW, I have CONFIG_DETECT_SOFTLOCKUP=y in my config.

Thanks,
Badari

This implys that a cpufreq module is getting registered twice in the

Full dmesg please, with CPU_FREQ_DEBUG=y, and boot with cpufreq.debug=7
Greg, could that warning be enhanced to print the object->name ?

I'm wondering if the processor driver has registered something
that acpi_cpufreq is also trying to do. Cc'ing linux-acpi

Subject: [2.6.25-rc5-mm1] regression: cannot run Postfix sendmail command as non-root

I'm noticing a strange effect with this:

On my openSUSE 10.3 development machine with SUSEs default MTA
Postfix installed, I occasionally send a pre-formatted mail by
feeding it directly into "/usr/sbin/sendmail -t". If I try that
while running a 2.6.25-rc5-mm1 kernel, I get:

ts@xenon:~/kernel> /usr/sbin/sendmail -t < patch-usb-reduce-syslog-clutter-v3
postdrop: warning: can't open /proc/net/if_inet6 (Permission denied) - skipping IPv6 configuration
postdrop: fatal: parameter inet_interfaces: no local interface found for ::1
sendmail: warning: command "/usr/sbin/postdrop -r" exited with status 1
sendmail: fatal: ts(1000): unable to execute /usr/sbin/postdrop -r: Success
ts@xenon:~/kernel>

and unsurprisingly, the mail is not sent. If I do the same as root,
everything works as usual, there is no console output from the
sendmail command, and the mail goes out as it should. All other
networking applications appear to be running normally.

On a 2.6.25-rc5 (non-mm) kernel I do not need to run the sendmail
command as root. It works just as well if I run it as myself.

IPv6 is not in use on that machine. The Ethernet interface has
just the link local IPv6 address. Possibly relevant information:

As you see, I can cat /proc/net/if_inet6 as regular (non-root) user
just fine, even though Postfix complains it cannot access it.
The content of /proc/net/if_inet6 is identical if I cat it on
kernel 2.6.25-rc5 mainline.

If you need more information or want me to test something, let me

Sure, that would be simple to do. Will change it now, and should show

Hi Tim,

Could you send me your full dmesg along with your kernel .config? i
think this is an ordering issue in bootup, but I'd like to be sure.
Bonus points if I can also have your initrd. :)

I'm really confused by this one. It looks to me like the initcalls got
all out of whack in their ordering. There's no way in hell that the
populate_rootfs() call should be happening right next to cpu
initialization:

If you can send me your vmlinux (not vmlinuz), I'll see how the
initcalls are laid out in it. What distro and compiler are you on?

CONFIG_PCIEASPM does not change anything.
Also testing the range of ipc patches you suggested to Badari did not fix it.

I did a bisect, these patches are currently remaining, but I dod not
have the time for more bisect steps until tomorrow:

git-scsi-misc
git-sh
execute-tasklets-in-the-same-order-they-were-queued
git-sched
sched: work around hrtick related lockup
sched: make sure jiffies is up to date before calling __update_rq_clock()
sched: fix rq->clock overflows detection with CONFIG_NO_HZ
sched: make cpu_clock() globally synchronous
sched: remove isolcpus
ftrace: make the task state char-string visible to all
sched: add latency tracer callbacks to the scheduler
latencytop: optimize LT_BACKTRACEDEPTH loops a bit
sched: cleanup old and rarely used 'debug' features.
[SCSI] zfcp: convert zfcp to use target reset and device reset handler
[SCSI] qla4xxx: Add target reset functionality
[SCSI] scsi_error: add target reset handler
[SCSI] ps3rom: Simplify fill_from_dev_buffer()
[SCSI] scsi_debug: use shost_priv macro
[SCSI] scsi_debug: remove unnecessary checking
[SCSI] scsi_debug: remove scsi_debug.h
[SCSI] scsi_debug: stop including drivers/scsi/scsi.h
[SCSI] Remove random noop unchecked_isa_dma users
[SCSI] aacraid: READ_CAPACITY_16 shouldn't trust allocation length in cdb
[SCSI] st: show options currently set in sysfs
[SCSI] st: add option to use SILI in variable block reads
[SCSI] gdth: remove command accessors
[SCSI] aic94xx: Use sas_request_addr() to provide SAS WWN if the
adapter lacks one
[SCSI] libsas: Provide a transport-level facility to request SAS addrs
[SCSI] ips: sg chaining support to the path to non I/O commands
[SCSI] gdth: convert to PCI hotplug API
[SCSI] gdth: PCI probe cleanups, prep for PCI hotplug API conversion
rtc: rtc-sh: Add support for periodic IRQs.

Yes. I found the following patch to be the culprit.

sched: make sure jiffies is up to date before calling __update_rq_clock
()

Torsten, looking at your output, it looks like it hung at the same
place. Backing out this patch should help. Try it out. I am sure
you also have CONFIG_DETECT_SOFTLOCKUP=y in your config ?

sched: make sure jiffies is up to date before calling
__update_rq_clock()

Now that __update_rq_clock() uses jiffies to detect clock overflows,
make sure jiffies are up to date before touch_softlockup_watchdog().

Removed a touch_softlockup_watchdog() call becoming redundant with
the
added tick_nohz_update_jiffies().

You can find it at

Ok, you asked for it. Find the lot at:

I guess you know what to expect, sizewise. :-)

(Don't worry about the cpufreq.debug note, that's for a different issue.)

openSUSE 10.3 and the toolchain it brought along, including GCC 4.2.1.

The interesting bits..

[ 46.075145] cpufreq-core: trying to register driver centrino

here we've done sysdev_driver_register(&cpu_sysdev_class,&cpufreq_sysdev_driver);
(see cpufreq_register_driver in drivers/cpufreq/cpufreq.c)
This is the only place we register sysdev entries.

[ 46.075163] speedstep-centrino: found unsupported CPU with Enhanced SpeedStep: send /proc/cpuinfo to [email protected]

this ENODEVs

[ 46.075176] cpufreq-core: initialization failed

Same for the 2nd CPU.

[ 46.075180] cpufreq-core: no CPU initialized for driver centrino

here we hit this part of cpufreq_register_driver

/* if all ->init() calls failed, unregister */
if (ret) {
dprintk("no CPU initialized for driver %s\n",
driver_data->name);
sysdev_driver_unregister(&cpu_sysdev_class,
&cpufreq_sysdev_driver);

So we release all the refs.

[ 46.075190] cpufreq-core: unregistering CPU 1

These are the sysdev callbacks.

Boom. I'm really puzzled. At this point, we shouldn't have any leaked refs
on the objects. Needs more thinking.

Please set CONFIG_ACPI_DEBUG and boot the system with the option of
"acpi.debug_layer=0x01010000 acpi.debug_level=0x1f".

It will be great if the acpidump output is attached.

Laurent, thanks a lot!

What was the state of consolechars? Where exactly did it hang? do_exit+??

Yes, currently I suspect we have another bug.

And. While doing this patch I forgot we should fix the bugs with init first!
(will try to make the patch soon).

Laurent, any chance you can try 2.6.25-rc5-mm1 + the patch below?
Unlikely it can help, but would be great to be sure.

CONFIG_ACPI_DEBUG is already set, but I cannot reboot the machine
right now. I'll probably get a chance for that in about 12 hours.

Tim, thanks for the excellent debugging info. It's making this much
easier. I actually booted your vmlinux in a kvm image and I got the
same error. However, it is in a *completely* bogus place. Certainly
before initcalls get run and before the lock you saw the BUG_ON() for
got initialized.

I'm going to go try and find a gcc-4.2 and compile on that.

Andrew, I don't think this is an actual bug in the r/o bind mount code,
but a random, way early call to populate_rootfs(), somehow. I'll keep
looking into it, though.

Notice in the dmesg that this all happens even before the first initcall
is made? It isn't the SMP alternates freeing, at least. I booted this
on SMP, too, with the same results.

For those of you new to this thread, here's the initial report:

http://marc.info/?t=120536629300001&r=1&w=2

I'm pretty sure the root cause of this bug is this commit:

ACPI: basic initramfs DSDT override support
71fc47a9adf8ee89e5c96a47222915c5485ac437

Which did this hunk:

@@ -648,6 +654,7 @@ asmlinkage void __init start_kernel(void)

check_bugs();

+ populate_rootfs(); /* For DSDT override from initramfs
*/
acpi_early_init(); /* before LAPIC and SMP init */

/* Do the rest non-__init'ed, we're now alive */
rest_init();
...

Well, the fs initcalls aren't actually done until during rest_init(),
including initializing my mnt_writer[] spinlocks. I guess I could
statically initialize them, but that's not the root of the problem, it's
just the canary in the coal mine.

I think the populate_rootfs() call is completely bogus and certainly
can't be done before the initcalls. But, I don't immediately have any
better suggestions for you. Can you delay the ACPI init until after the
fs initcalls are made?

Time to just revert that one? It caused some other issues too, iirc.

Hi,

I have made a patch to fix problems with regards to early userspace
calls (http://lkml.org/lkml/2008/2/23/306) but I don't think it will
solve this bug. So far I had not heard of problems with filesystem
initialization.

I'm not sure it would be possible to delay acpi_early_init() until after
the fs initcalls. Maybe Len knows. How about trying the opposite: what
is the barely minimum to initialize so that the rootfs can be populated
and read? Would it be possible to have a kind of
early_mnt_writer_initialize() that would do that?

See you,
Eric

I *can* probably do it earlier, maybe even statically, but I think
you're missing the point a bit here. We've just been super lucky so far
that populate_rootfs() doesn't depend on any other initcalls (or at
least BUG_ON() because of them). There may be some more buglets hiding
around.

It'd be a shame to have to have "super_early_fs_initcall()" logic for
every part of the VFS or any other initcall for that matter that you
might need. How do we tell all future VFS hackers that they have to do
this so that the next guy doesn't break it? I certainly missed it. :)

We could separate out the initcalls and just have the fs ones run before
the rest do. But, I'm not sure what interactions *THAT* might have.
There are arch-specific initcalls, and I have no idea if the fs init
code depends on *those*. That's a lot of code to check.

It is nailed when you the patch says:

+ /*

I think requiring FS access this early in the boot processes is just
broken. It seems like the author of the patch knew a better way and
tried to get away with a hack. I think it backfired. :)

Actually, each time I look at init/main.c I feel like we are super lucky
that Linux boots ;-)

Well, my point was that actually populate_rootfs() does _very_ little
with regard to FS manipulation, acpi_find_dsdt_initrd() even less. The
task of checking that everything needed is available beforehand is
certainly not the same magnitude as the one of the Danaides as you
seemed to implied ;-)

The fact is, this patch has been tested a lot, because it's been used by
several distributions for a long time. I expect that the only potential
problems are corner cases that are possible to work around.

Yes, we agree on this. That would be crazy :-)

I'm actually the author of this comment... The static/init firmware
infrastructure that I mentioned was more just about a way to hide the fs
access in a special part of the kernel, not avoiding it. We used to have
a different way but it was even uglier: append the DSDT after the
initramfs, and then access it _directly_. This implies teaching
populate_rootfs() to not panic when seeing DSDTs and loosing the benefit
of the compression.

That said, I'm really not against any complete different approach. All
that is needed is being able to read a file early at boot (the DSDT)
without having to recompile the kernel each time the file is modified.
For instance someone had once mentioned modifying the in-kernel DSDT by
unlinking and relinking the bzimage. If one can show me how to do that
I'd be happy to implement it...

The problem is defining how much "very little" is, and making sure that
all the other kernel developers agree with you on it.

Anyway, I'm sick of too much bitching and too little coding. Andrew,
here's a patch for -mm that will at least shut up the spinlock warnings.
Al, you'll also need something similar to this for when you get Linus to
pull your git tree that has the r/o bind mount patches.
It's a hack, but I don't know any better way to do it until the ACPI
mess gets cleaned up.

Arjan, is there a way to statically set lockdep classes for a spinlock
that I'm missing?

I'll leave it to everyone else to describe the evils of calling into
*any* fs code before the fs initcalls have been made.

-- Dave

I'm not happy with this patch, but I don't see an easier way
to do it. We can't statically initialize the lockdep classes
as far as I can see.

Great. Thanks a lot Laurent!

So what happens is:

We have the very old bug (bugs, actually) with the global init && signals
which I tried to fix many times but can't find a simple solution. The fatal
signal sent to init doesn't really kill it (we have the check in
get_signal_to_deliver) but it sets SIGNAL_GROUP_EXIT. This is wrong, now
init can't exec, this has other bad implications, and this is just insane.

With the signals-send_signal-factor-out-signal_group_exit-checks.patch the
task with SIGNAL_GROUP_EXIT doesn't recieve the signals. While this change
itself is (I hope) correct, the "killed" /sbin/init now can't see SIGCHLD
and the system hangs on boot.

Not a kernel problem, but this looks a bit strange to me.

init has SIG_DFL for SIGUSR1, and someone does kill(1, SIGUSR1).
Note that init was explicitly targeted, the signal was not sent
to prgp or -1.

Most likely Ubuntu knows what it does, and I can't find any email
at ubuntu.com to cc...

Ok, that took a bit longer than I hoped, but the result is now
finally available at:

http://gollum.phnxsoft.com/~ts/linux/dmesg-acpidebug.out

Note that I doctored this a bit: the dmesg buffer had already
overflowed by the time I ran the dmesg command, so I manually
prepended the missing part from the file /var/log/boot.msg into
which SUSE saves the early kernel messages. The border between
the two is marked off by the string "~~~~~~~~splice~~~~~~~~",
and I left a line of overlap to make it very clear.

The output of acpidump is unchanged wrt what I already posted.
(Unsurprisingly, but nevertheless I checked. Call me paranoid. ;-)

Sorry to say, it doesn't. That is, it does shut up the warning I

I've reverted the whole thing. Or rather, since there were various small
fixup commits over time, and a simple revert doesn't really work, I ended
up just removing the option and the code that was conditional on it - that
way, if we really want to fight this out some time (after 2.6.25 is out)
or some vendor wants to use a known-broken option anyway, there's a simple
and fairly clean commit to revert the revert.

It's commit 9a9e0d685553af76cb6ae2af93cca4913e7fcd47, see

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=9a9e0d685553af76cb6ae2af93cca4913e7fcd47

for details if you aren't a git person.

But quite frankly I don't think that we even want to re-introduce this in
that form. If we really want to have a dynamic custom DSDT, I think we
should do the whole DSDT replacement *much* later by ACPI (like just
before driver loading or something like that).

If the BIOS-provided DSDT is _so_ broken that we cannot even get core
stuff like the CPU's going, I think it has more serious issues than any
custom DSDT will ever fix, but letting ACPI actually switch DSDT's at
run-time (instead of just replacing it when looking for it very very early
in the boot sequence) in order to work around some device issues sounds
reasonably sane.

So how about aiming to make that DSDT-replacement something you can do
from any kernel module, _after_ the original DSDT has already been parsed?
And then the whole "load it from initrd" turns into a regular thing that
we can do pretty early, but that we don't have to do quite _this_ early!

Subject: [PATCH 1/1] DSDT in initramfs: directly access the initramfs

The current method for reading the DSDT in the initramfs uses the filesystem. Not only this is bad because such functions should normally not used in the kernel, but in addition it brings the requirement that the filesystem infrastructure is already initialised before initialising ACPI. This is quite unlikely to ever happen. (cf http://marc.info/?t=120536629300001&r=1&w=2)

This patch changes the method of access to initramfs. It uses directly unpack_to_rootfs(). This is build over the "check_only" mode: the initramfs is just read... but if we find a file matching the one we are looking for we copy it to memory.

So that avoids the VFS layer issues, but it's still strictly much worse
than just having a run-time loading.

What's the problem with just loading a new DSDT later? Potentially as in
*much* later: including when user-space is all up-and-running?

For things like DVD install images, you'd quite possibly want to have a
few known-workaround DSDT images with the installer, and just say "ok, we
want to fix up this ACPI crap in order to get working suspend/resume" kind
of thing.

So what's the reason for pushing for this insanely-early workaround in the
first place, instead of letting user-space do something like

cat my-dsdt-image > /proc/sys/acpi/DSDT

or whatever at runtime?

Yeah, or probably more something like this nowadays ;-)
cat my-dsdt-image > /sys/firmware/acpi/tables/DSDT

As I said in my previous email, I'm already convinced that late-override
of ACPI table approach would be very interesting to investigate.
However, this cannot be taken lightly. A _lot_ of places in the kernel
depend on the ACPI and nothing has ever been done in the direction of
dynamic modification of the APCI tables. The implementation is likely to
be much bigger than the current 100 lines of patch.

That said, it should be possible to draw some assumptions without
restraining much the functionality. Such as:
* every object present in the original table is still present is the
new table
* they keep the same name

Len, do you think it would be feasible? How do you think the
implementation could be done?

Hi Tim,

Again, thanks for the excellent bug reporting.

This is actually a different problem (and not my code again, thank
goodness). I think a few of these got fixed in current -mm. According
to Peter Z, these mean:

So, this looks like an on-stack ACPI structure that got initialized
wrongly. At least we already have those dudes on the cc. :)

But, this might also get fixed by reverting the patch as Linus just did.
It might just be best to wait for another -mm release and see how it
settles out.

Thanks,

I was not able to reproduce it, but I think I didn't configured postfix
as I should had. What version do you use ?
If I may ask you, can you put your postfix configuration file and a
strace -f of your failing command ? on your website, that will help me a
lot to investigate.

Actually looks like the semaphore thing again, its a spinlock inside of
down_tylock().

Looks like another of the semaphore thingies.. Does this go away once
you apply the semaphore lockdep fixup from here:

I also tried to reproduce your problem with Postfix (on a Debian

obtain the error message.

While googling for the error string, I found this link which report
the same kind of
error when Postfix is used with grsecurity (in 2006):

The userspace failure described there is indeed the same as mine:
Postfix' sendmail command tries to open "/proc/net/if_inet6"
which fails with EACCES.

But I have never installed grsecurity on this machine, and the
problem appeared for me only with kernel 2.6.25-rc5-mm1, not when
running kernel 2.6.25-rc5 on the same machine, so I guess the
cause must be something different.

What's also strange is that I can "cat /proc/net/if_inet6" from
the command line as the same non-root user with no problem at all.
strace of "cat /proc/net/if_inet6" has:

open("/proc/net/if_inet6", O_RDONLY|O_LARGEFILE) = 3

strace of "/usr/sbin/sendmail", however:

open("/proc/net/if_inet6", O_RDONLY) = -1 EACCES (Permission denied)

Both run as

ts@xenon:~> id
uid=1000(ts) gid=100(users) groups=0(root),14(uucp),16(dialout),33(video),100(users),112(bacula)

I agree with Linus' decision to revert/disable this feature.
I think it is appropriate to muck with this in -mm, but not in -rc6
Kudos to Christoph, who recommended we revert it back at -rc2.

I don't think re-loading the DSDT at run-time would be practical.

First, booting with the OEM DSDT may nullify the benefit
of overriding the OEM DSDT -- the damage may have already been done.

Secondly, unwinding everything that depends on the DSDT is on the
order of kexec or suspend/resume. We're talking about all the stuff
that PNP does at boot time, plus device discovery and driver binding.

The feature on the table here is an initrd DSDT override.
We already have the ability to statically compile a DSDT
override into the kernel image. That capability is sufficient
for kernel developers.

The initrd version of the DSDT override is really for one scenario.
Somebody who has a BIOS that even Windows can't deal with -- so
no amount of "Windows bug compatbility" will help Linux with it.
They must be capable eough to generate or acquire a modified DSDT.
They must be unwilling/unable to re-build their kenrel from scratch
each time they update it. Eg. following debian unstable updates etc.

I think that customer deserves support, particularly because they get
bragging rights that Linux works better on a box build for Windows
than Windows does:-)
However, I don't think there are enough customers like this to
justify a huge effort that would add risk to Linux.

For a Linux distro to ship DSDT override images, they'd have to
have some licensing & support arrangement with the OEM
who actually owns that BIOS code.

While this wouldn't defy any laws of physics, it doesn't
look compatible with current industry business practices.

OEMs are more likely to simply ship a BIOS update ISO.

DSDT's are generally 4KB to 64KB, so I don't think compression
for a DSDT override is important.

I recommend that you make a new proposal for 2.6.26
that applies on top of Linus' top-of-tree and that we
include lkml in hashing it out rather than just linux-acpi.

Subject: Re: [2.6.25-rc5-mm1] regression: cannot run Postfix sendmail command as non-root

Tilman,

I've finally managed to reproduce your problem with Postfix on one of
my victims.

Earlier, in the afternoon, I wrote a piece of code that triggered a
similar behaviour,
but I wasn't sure it was exactly the problem you found. So, I've
rebuilt Postfix, added
some traces and, voila, same issue as yours.
(The version of Postfix originally installed on my machine seems to
have IPv6 disabled)

I bisected the problem to the commit "[NET]: Make /proc/net a symlink
on /proc/self/net (v3)"

Here is what happens:

- Recently /proc/net has been moved to /proc/self/net, and
/proc/self/net is a symlink
on this directory.
- Before that everybody could access /proc/net and read /proc/net/if_inet6:
dr-xr-xr-x 6 root root 0 2008-03-05 15:23 /proc/net

- Now, /proc/self/net has a more restrictive access mode and ony the
owner of the
process can enter the directory:
dr-xr--r-- 5 toto toto 0 Mar 19 17:30 net

This is not a problem in most of the cases, but it becomes annoying
when a process
decides to change its UID or GID. It may loose access to its own
/proc/self/net entries.

- What happens in the Postfix case is the 'sendmail' process executes the
'/usr/sbin/postdrop' binary to enqueue the message, but unfortunately
'/usr/bin/postdrop' has the setgid bit set:
-rwxr-sr-x 1 root postdrop 479475 Mar 19 17:14 /usr/sbin/postdrop

The process egid changes and this seems to be problematic to access
/proc/self/net/if_inet6. :)

I've attached a tiny test program that can be used to reproduce the problem
without Postfix.
- Either execute it as root and give it an unprivileged uid in argument
./test-proc_net_if_inet6 1001

- Or change its ownership and access mode to: -rwxr-sr-x root postdrop
and execute it as a lambda user.
chown root:postdrop test-proc_net_if_inet6; chmod 2755 test-proc_net_if_inet6
./test-proc_net_if_inet6

I've found the cause but not the fix. :)
(Adding Pavel in cc:)

Benjamin

Thanks for that - most useful.

Although this is advertised as a 2.6.25-rc5-mm1 problem, I assume the
regression is also in mainline? 2.6.25-rc6?

Yes, it is in mainline. I reproduced it on 2.6.25-rc5.

It is in 2.6.25-rc6, correct.

If Pavel or someone else doesn't produce a good fix soon
I'll revert the guilty change as this bug is worse than
the problem that changeset fixes.

My results:

up to 2.6.25-rc5 -- good
2.6.25-rc5-mm1 -- bad
2.6.25-rc6 -- bad

Thomas,
The justification above is what convinced me
that we should try to integrate this feature.
Further, although we failed in 2.6.25,
I think we should continue to try to get this capability integrated.

If you think it will be useful for additional purposes, that's great.
As you know, I'm somewhat skeptical, as I've seen huge mistakes such
as a database of modified BIOS images created and used when the users
have absolutely no idea what they're doing. But we don't have to
agree on this to move forward.

thanks,

But even here we now have the only existing database for some research.

I think we fully agree.
I don't mind to add a message in big letters: "Only override the DSDT
for debugging, please report any findings" or whatever, we can add this
ten times in a row, still it is an important feature which is worth
pushing (and getting populate_root_fs being able to be executed earlier
is a feature others also like to see AFAIK).

You have interpretted code runing (AML), and you want to replace it
with different code?

Akin to changing from one kernel to different during runtime?

Yes, I guess it might work for very simple changes, but if you need to change
data structures between origina and modified DSDT, you are in for a
big trouble, right?

Heh. That gave me an idea.

Can we use kexec for this? Let's say you get as far in boot as the
initrd and realize that you're running on one of these screwed up
systems. Can you stick the new DSDT somewhere known (and safe) in
memory, and kexec yourself back to the beginning of the kernel boot?

When you boot up the second time, you have the new, shiny DSDT there
which is, of course, used instead of the bogus BIOS one.

It costs you some bootup time, but we're talking about working around
really busted hardware here.

Hmmm. I guess we should turn off acpi mode, kexec, turn on acpi mode
with new dsdt.

Turning off acpi is not exactly easy, but specs describe how to do
it...

So yes, this is hard but doable.

Why do you think it's necessary to turn off acpi mode? What will not
work if we keep it on all the time?

BTW, let me summarize my understanding of the kexec approach:
* the userspace write the new DSDT (cat my-dsdt-image >
/sys/firmware/acpi/tables/DSDT)
* the kernel don't use this DSDT directly but keeps it somewhere warm
and fuzzy in the RAM
* userspace does a kexec
* the new kernel boots and at some (early) point, dsdt_override() is
called. It detects that the special place in the RAM for a new DSDT is
used. It provides this pointer to ACPI as the new place to read the DSDT.

Dave, am I correctly understanding the scenario you had in mind?

I have pratically no knowledge of kexec. Is there a documented way to
pass big chunk of data from one kernel to another one? How can I do that?
