- Added the kexec code. Again. This was in -mm a year or so ago but didn't
make it.
- This kernel has an x86 patch which alters the copy_*_user() functions so
they will return -EFAULT on a fault rather than the number of bytes which
remain to be copied. This is a bit of an experiment, because this seems to
be the preferred API for those functions. It's a see-what-breaks thing.
And things will break. If weird behaviour is observed, please revert
usercopy-return-EFAULT.patch and send a report.

It only boots with acpi=off, hangs after outputting "starting sound
driver: intel8x0", but looks like an ACPI bug. Tried pci=routeirq and
pci=noacpi also.
Athlon 3000+/512M, Asus A7N8X-E, nForce2 chipset.

Sid.

PCI: Using ACPI for IRQ routing
** PCI interrupts are no longer routed automatically. If this
** causes a device to stop working, it is probably because the
** driver failed to call pci_enable_device(). As a temporary
** workaround, the "pci=routeirq" argument restores the old
** behavior. If this argument makes the device work again,
** please email the output of "lspci" to bjorn.helgaas@hp.com
** so I can fix the driver.

Hopefully it will this round :)
There is a null pointer dereference bug in ide_print_status,
the following patch allows me to boot.
The function still looks fishy as there is another access
to rq outside of ide_lock, a few lines earlier.

HWGROUP(drive) is always valid for any live device. If this goes non
valid you have another bug and you need to fix the HWGROUP(drive) bug.

So long as I don't have to claim it :)
What I know is an IDE bug introduced between 2.6.8.1 and 2.6.8.1-mm4.
So far all I have done is spent a couple of minutes tracking
down my the kernel was oops on bootup.
The new code introduced between those two kernels seems
to be the enhancement to ide_dump_status introduced in
ide-disk-barrier.patch The amd74x driver has remained
the same. So if ide_dump_status is correct it appears
it has uncovered and old bug.
Here is the oops that I get without this patch. The drive
in question is a compact flash device. So it implements
only a minimal number of ide commands. Which explains the
presence of errors.
There is a truly trivial amount of driver specific code
on this path. So if the problem is not the code I patched
it appears to be a generic IDE bug.
Also attached are my complete boot logs in the patched and
unpatched case.

Things appear to broke. Sometimes kernel starts to spit page allocation
failures into log for few minutes, despite memory beeing available:
total used free shared buffers
cached
Mem: 255244 251436 3808 0 16812
44068
-/+ buffers/cache: 190556 64688
Swap: 262136 148924 113212
Previously I've used -mm2 which worked fine. The failures seem network
related, I have e1000 and few rules in iptables.

I am unable to reboot now, so I won't check it. :(
My config attached just in case. Here what's now in my dmesg:

The kernel relies on copy_from_user returning the number of bytes copied
so no suprise there. In fact if it returns -EFAULT and you've not
reworked all the drivers (including out of kernel serial drivers in
particular) you get a security hole because you can move the buffer
pointers backwards.
Other code uses it to decide what object was passed for compatibility
too.

Sorry thats what I meant to say but got it backwards. There are a lot of
users of the value actually - all the serial drivers for example use it
to get the right results. Networking too gets fun because you can send a
packet and want to report that you did something before the fault
occurred. True POSIX doesn't seem to require this behaviour (I guess it
wants to define passing bogus addresses as undefined because of MMUless
systems and library emulation of calls).

Who cares? Faults are not fast paths. Also if I understand sparc64
correctly it doesn't have to go back and copy one at a time because a
fault can only occur on a page boundary. That means for the normal case
you already know where the fault occurred and for the unusual case its
one probe per page, all non fast-path.

Noooo. copy_*_user() returns zero on success and "number of bytes
remaining to be copied" on fault. The number of places in the kernel which
actually care about the precision of the "number remaining to be copied"
thing is very small. Most places just test for non-zeroness.
The problem is that the current semantics are hard to implement on several
architectures. To get it right, sparc64 has to go back and copy one byte
at a time just to work out the address at which the fault really occurred.

task_vsize() doesn't need mm->mmap_sem for the CONFIG_MMU case; the
semaphore doesn't prevent mm->total_vm from going stale or getting
inconsistent with other numbers regardless. Also, KSTK_EIP() and
KSTK_ESP() don't want or need protection from mm->mmap_sem either. So
this pushes mm->mmap_sem to task_vsize() in the CONFIG_MMU=n task_vsize().
Also, hoist the prototype of task_vsize() into proc_fs.h
The net result of this is a small speedup of procps for CONFIG_MMU.

Networking doesn't check the return value any more Alan.
What it does do is not return the error if we moved
some bytes already from the socket (from a previous
iovec entry, for example).
Even the pipe code, which is what instigated this silly
return value to begin with, doesn't even check it any
more.
Even the serial driver cases you mention, which I have
looked at, can be converted neatly.
This is really the right change. Or, care to audit and
fix every platform's user copy implementation? :-) People
who are experts and work every day on their platform get
this stuff wrong, myself included. This means we are too
dumb to debug this code, according to The Practice of
Programming :-) When people get this wrong it's exploitable,
as you mentioned, so double the reason to make it as simple
as possible.

I'd prefer it if you (and everyone else) could give a meaningful
English-language Subject: to patches, please.
A well-chosen patch Subject: becomes a sort of globally-unique key by which
the patch is tracked - I munge it into a patch filename and it propagates
all the way into bitkeeper. It can be used for searching email folders,
googling, inter-developer discussion, etc, etc.
Thanks.
