radio are installed on the same system, and the one without radio is
registered first, then radio_open checks for the radio device number

15 years agortc: fix kernel panic on second use of SIGIO nofitication
Marcin Slusarz [Fri, 3 Oct 2008 22:23:36 +0000 (15:23 -0700)]
rtc: fix kernel panic on second use of SIGIO nofitication

When userspace uses SIGIO notification and forgets to disable it before
closing file descriptor, rtc->async_queue contains stale pointer to struct
file.  When user space enables again SIGIO notification in different
process, kernel dereferences this (poisoned) pointer and crashes.

So disable SIGIO notification on close.

Kernel panic:

selinux: Fix an uninitialized variable BUG/panic in selinux_secattr_to_sid()

At some point during the 2.6.27 development cycle two new fields were added
to the SELinux context structure, a string pointer and a length field.  The
code in selinux_secattr_to_sid() was not modified and as a result these two
fields were left uninitialized which could result in erratic behavior,
including kernel panics, when NetLabel is used.  This patch fixes the
problem by fully initializing the context in selinux_secattr_to_sid() before
use and reducing the level of direct context manipulation done to help
prevent future problems.

Please apply this to the 2.6.27-rcX release stream.

("[S390] nohz/sclp: disable timer on synchronous waits.").
If udelay() gets called from a disabled context it sets the clock comparator
to a value where it expects the next interrupt. When the interrupt happens
the clock comparator gets not reset and therefore the interrupt condition
doesn't get cleared. The result is an endless timer interrupt loop.

In addition this patch fixes also the following:

rcutorture reveals that our __udelay implementation is still buggy,
since it might schedule tasklets, but prevents their execution:

NOHZ: local_softirq_pending 42
NOHZ: local_softirq_pending 02
NOHZ: local_softirq_pending 142
NOHZ: local_softirq_pending 02

To fix this we make sure that only the clock comparator interrupt
is enabled when the enabled wait psw is loaded.
Also no code gets called anymore which might schedule tasklets.

15 years agoCheck mapped ranges on sysfs resource files
Linus Torvalds [Fri, 3 Oct 2008 01:52:51 +0000 (18:52 -0700)]
Check mapped ranges on sysfs resource files

This is loosely based on a patch by Jesse Barnes to check the user-space
PCI mappings though the sysfs interfaces.  Quoting Jesse's original
explanation:

  It's fairly common for applications to map PCI resources through sysfs.
  However, with the current implementation, it's possible for an application
  to map far more than the range corresponding to the resourceN file it
  opened.  This patch plugs that hole by checking the range at mmap time,
  similar to what is done on platforms like sparc64 in their lower level
  PCI remapping routines.

  It was initially put together to help debug the e1000e NVRAM corruption
  problem, since we initially thought an X driver might be walking past the
  end of one of its mappings and clobbering the NVRAM.  It now looks like
  that's not the case, but doing the check is still important for obvious
  reasons.

and this version of the patch differs in that it uses a helper function
to clarify the code, and does all the checks in pages (instead of bytes)
in order to avoid overflows when doing "<< PAGE_SHIFT" etc.

When we initialise a compound page we initialise the page flags and head
page pointer for all base pages spanned by that page.  When we initialise
a gigantic page (a page of order greater than or equal to MAX_ORDER) we
have to initialise more than MAX_ORDER_NR_PAGES pages.  Currently we
assume that all elements of the mem_map in this page are contigious in
memory.  However this is only guarenteed out to MAX_ORDER_NR_PAGES pages,
and with SPARSEMEM enabled they will not be contigious.  This leads us to
walk off the end of the first section and scribble on everything which
follows, BAD.

When we reach a MAX_ORDER_NR_PAGES boundary we much locate the next
section of the mem_map.  As gigantic pages can only be maximally aligned
we know this will occur at exact multiple of MAX_ORDER_NR_PAGES pages from
the start of the page.

This is a bug fix for the gigantic page support in hugetlbfs.

board to hang at boot.  The MPC8544DS is unique in that it doesn't use
the PCI slots on the ULI (unlike the MPC8572DS or MPC8610HPCD).  So
the dummy read at the end of the address space causes us to hang.

We can detect the situation by comparing the bridge's BARs versus
the root complex.

David Howells [Wed, 1 Oct 2008 12:47:06 +0000 (13:47 +0100)]
MN10300: Fix IRQ handling

Fix the IRQ handling on the MN10300 arch.

This patch makes a number of significant changes:

 (1) It separates the irq_chip definition for edge-triggered interrupts from
     the one for level-triggered interrupts.

     This is necessary because the MN10300 PIC latches the IRQ channel's
     interrupt request bit (GxICR_REQUEST), even after the device has ceased to
     assert its interrupt line and the interrupt channel has been disabled in
     the PIC.  So for level-triggered interrupts we need to clear this bit when
     we re-enable - which is achieved by setting GxICR_DETECT but not
     GxICR_REQUEST when writing to the register.

     Not doing this results in spurious interrupts occurring because calling
     mask_ack() at the start of handle_level_irq() is insufficient - it fails
     to clear the REQUEST latch because the device that caused the interrupt is
     still asserting its interrupt line at this point.

 (2) IRQ disablement [irq_chip::disable_irq()] shouldn't clear the interrupt
     request flag for edge-triggered interrupts lest it lose an interrupt.

 (3) IRQ unmasking [irq_chip::unmask_irq()] also shouldn't clear the interrupt
     request flag for edge-triggered interrupts lest it lose an interrupt.

 (4) The end() operation is now left to the default (no-operation) as
     __do_IRQ() is compiled out.  This may affect misrouted_irq(), but
     according to Thomas Gleixner it's the correct thing to do.

 (5) handle_level_irq() is used for edge-triggered interrupts rather than
     handle_edge_irq() as the MN10300 PIC latches interrupt events even on
     masked IRQ channels, thus rendering IRQ_PENDING unnecessary.  It is
     sufficient to call mask_ack() at the start and unmask() at the end.

 (6) For level-triggered interrupts, ack() is now NULL as it's not used, and
     there is no effective ACK function on the PIC.  mask_ack() is now the
     same as mask() as the latch continues to latch, even when the channel is
     masked.

Further, the patch discards the disable() op implementation as its now the same
as the mask() op implementation, which is used instead.

It also discards the enable() op implementations as they're now the same as
the unmask() op implementations, which are used instead.
