The termios settings ioctls on a pty should affect the bound tty side not
the pty. The SOFTCAR ioctls use the wrong device file.

10 years agoftrace: disable tracing for suspend to ram
Steven Rostedt [Wed, 27 Aug 2008 13:14:40 +0000]
ftrace: disable tracing for suspend to ram

I've been painstakingly debugging the issue with suspend to ram and
ftraced. The 2.6.28 code does not have this issue, but since the mcount
recording is not going to be in 27, this must be solved for the ftrace
daemon version.

The resume from suspend to ram would reboot because it was triple
faulting. Debugging further, I found that calling the mcount function
itself was not an issue, but it would fault when it incremented
preempt_count. preempt_count is on the tasks info structure that is on the
low memory address of the task's stack.  For some reason, it could not
write to it. Resuming out of suspend to ram does quite a lot of funny
tricks to get to work, so it is not surprising at all that simply doing a
preempt_disable() would cause a fault.

Thanks to Rafael for suggesting to add a "while (1);" to find the place in
resuming that is causing the fault. I would place the loop somewhere in
the code, compile and reboot and see if it would either reboot (hit the
fault) or simply hang (hit the loop).  Doing this over and over again, I
narrowed it down that it was happening in enable_nonboot_cpus.

At this point, I found that it is easier to simply disable tracing around
the suspend code, instead of searching for the particular function that
can not handle doing a preempt_disable.

This patch disables the tracer as it suspends and reenables it on resume.

I tested this patch on my Laptop, and it can resume fine with the patch.

Linus Torvalds [Wed, 27 Aug 2008 20:35:31 +0000]
Revert "pktcdvd: push BKL down into driver"

This reverts commit 5b6155ee70e9c4d2ad7e6f514c8eee06e2711c3a, because
the block device ioctl's really aren't ready for it.

In particular, the "struct file *" and the "struct inode *" arguments do
not necessarily match, which means that the unlocked version of the
ioctl (that only gets a "struct file *") isn't actually able to handle
the cases it needs to handle.

This fixes bugzilla

This patch changes the interface of the cmd filter to use a +/-
notation like:

echo -- +0x02 +0x03 -0x08

If neither + or - is given it defaults to + (allow command).

Note: The interface was added in 2.6.17-rc1 and is unused and
undocumented so far so it's safe to change it.

10 years agoblock: move cmdfilter from gendisk to request_queue
FUJITA Tomonori [Sat, 16 Aug 2008 05:10:05 +0000]
block: move cmdfilter from gendisk to request_queue

cmd_filter works only for the block layer SG_IO with SCSI block
devices. It breaks scsi/sg.c, bsg, and the block layer SG_IO with SCSI
character devices (such as st). We hit a kernel crash with them.

The problem is that cmd_filter code accesses to gendisk (having struct
blk_scsi_cmd_filter) via inode->i_bdev->bd_disk. It works for only
SCSI block device files. With character device files, inode->i_bdev
leads you to struct cdev. inode->i_bdev->bd_disk->blk_scsi_cmd_filter
isn't safe.

SCSI ULDs don't expose gendisk; they keep it private. bsg needs to be
independent on any protocols. We shouldn't change ULDs to expose their
gendisk.

This patch moves struct blk_scsi_cmd_filter from gendisk to
request_queue, a common object, which eveyone can access to.

The user interface doesn't change; users can change the filters via
/sys/block/. gendisk has a pointer to request_queue so the cmd_filter
code accesses to struct blk_scsi_cmd_filter.

powerpc/ps3: Fix ioremap of spu shadow regs

Fix the ioremap of the spu shadow regs on the PS3.

The current PS3 hypervisor requires the spu shadow regs to be
mapped with the PTE page protection bits set as read-only (PP=3).
This implementation uses the low level __ioremap() to bypass the
page protection settings inforced by ioremap_flags() to get the
needed PTE bits set for the shadow regs.

This fixes a runtime failure on the PS3 introduced by the powerpc
ioremap_prot rework of commit a1f242ff460e4b50a045fa237c3c56cce9eabf83

10 years ago[x86] Clean up MAXSMP Kconfig, and limit NR_CPUS to 512
Linus Torvalds [Mon, 25 Aug 2008 21:15:38 +0000]
[x86] Clean up MAXSMP Kconfig, and limit NR_CPUS to 512

This fixes a regression that was indirectly caused by commit
1184dc2ffe2c8fb9afb766d870850f2c3165ef25 ("x86: modify Kconfig to allow
up to 4096 cpus").

Allowing 4k CPU's is not practical at this time, because we still have a
number of places that have several 'cpumask_t's on the stack, and a
4k-bit cpumask is 512 bytes of stack-space for each such variable.  This
literally caused functions like 'smp_call_function_mask' to have a 2.5kB
stack frame, and several functions to have 2kB stackframes.

With an 8kB stack total, smashing the stack was simply much too likely.
At least bugzilla entry

http://bugzilla.kernel.org/show_bug.cgi?id=11342

was due to this.

The earlier commit to not inline load_module() into sys_init_module()
fixed the particular symptoms of this that Alan Brunelle saw in that
bugzilla entry, but the huge stack waste by cpumask_t's was the more
direct cause.

Some day we'll have allocation helpers that allocate large CPU masks
dynamically, but in the meantime we simply cannot allow cpumasks this
large.

 kernel unaligned access to 0xe000000644220466, ip=0xa000000100516fa1

This was tracked to ide code using the __cmd[] field in "struct request"
via the __outsw() function.  __cmd[] is a char array, so is not guaranteed
to be properly aligned when accessed as words.

Linus Torvalds [Mon, 25 Aug 2008 18:10:26 +0000]
[module] Don't let gcc inline load_module()

'load_module()' is a complex function that contains all the ELF section
logic, and inlining it is utterly insane.  But gcc will do it, simply
because there is only one call-site.  As a result, all the stack space
that is allocated for all the work to load the module will still be
active when we actually call the module init sequence, and the deep call
chain makes stack overflows happen.

And stack overflows are really hard to debug, because they not only
corrupt random pages below the stack, but also corrupt the thread_info
structure that is allocated under the stack.

In this case, Alan Brunelle reported some crazy oopses at bootup, after
loading the processor module that ends up doing complex ACPI stuff and
has quite a deep callchain.  This should fix it, and is the sane thing
to do regardless.

[IA64] Fix ia64 build failure when CONFIG_SFC=m

CONFIG_SFC=m uses topology_core_siblings() which, for ia64, expects

Maintainers note: This really looks like the wrong thing to do ... it
would be much better for the kernel to export an API to provide
drivers like this with data they need (which in the case of this
driver seems to be an estimate of the effective parallelism available
on the platform).  But x86 has exported this forever ... so go with

10 years agosched_clock: fix cpu_clock()
Peter Zijlstra [Mon, 25 Aug 2008 15:15:34 +0000]
sched_clock: fix cpu_clock()

This patch fixes 3 issues:

a) it removes the dependency on jiffies, because jiffies are incremented
   by a single CPU, and the tick is not synchronized between CPUs. Therefore
   relying on it to calculate a window to clip whacky TSC values doesn't work
   as it can drift around.

   So instead use [GTOD, GTOD+TICK_NSEC) as the window.

b) __update_sched_clock() did (roughly speaking):

   delta = sched_clock() - scd->tick_raw;
   clock += delta;

   Which gives exponential growth, instead of linear.

c) allows the sched_clock_cpu() value to warp the u64 without breaking.

the results are more reliable sched_clock() deltas:

KVM: Use .fixup instead of .text.fixup on __kvm_handle_fault_on_reboot

vmlinux.lds expects the fixup code to be on a section named .fixup. The
.text.fixup section is not mentioned on vmlinux.lds, and is included on

placing orphan sections.

However, placing .text.fixup outside .text breaks the definition of
_etext, making it exclude the .text.fixup contents. That makes .text.fixup
be ignored by the kernel initialization code that needs to know about

Both v and vb->num_pages are u32 and unsigned int respectively.  If v is less
than vb->num_pages (and it is, when deflating the balloon), the result is a
very large 32-bit number.  Since we're returning a s64, instead of getting the
same negative number we desire, we get a very large positive number.

This handles the case where v < vb->num_pages and ensures we get a small,
negative, s64 as the result.

* codec is allocated in the platform device probe function, but is not

11 years agox86: fix HPET regression in 2.6.26 versus 2.6.25, check hpet against BAR, v3

x86: fix HPET regression in 2.6.26 versus 2.6.25, check hpet against BAR, v3

David Witbrodt tracked down (and bisected) a hpet bootup hang on his
system to the following problem: a BIOS bug made the hpet device
visible as a generic PCI device. If e820 reserved entries happen to
be registered first in the resource tree [which v2.6.26 started doing],
then the PCI code will reallocate that device's BAR to some other
address - breaking timer IRQs and hanging the system.

( Normally hpet devices are hidden by the BIOS from the OS's PCI
  discovery via chipset magic. Sometimes the hpet is not a PCI device
  at all. )

Solve this fundamental fragility by making non-PCI platform drivers
insert resources into the resource tree even if it overlaps the e820
reserved entry, to keep the resource manager from updating the BAR.

Also do these checks for the ioapic and mmconfig addresses, and emit
a warning if this happens.
