12 years ago[PATCH] uml: make execvp safe for our usage
Paolo 'Blaisorblade' Giarrusso [Sat, 25 Nov 2006 19:09:39 +0000]
[PATCH] uml: make execvp safe for our usage

Reimplement execvp for our purposes - after we call fork() it is fundamentally
unsafe to use the kernel allocator - current is not valid there.  So we simply
pass to our modified execvp() a preallocated buffer.  This fixes a real bug
and works very well in testing (I've seen indirectly warning messages from the
forked thread - they went on the pipe connected to its stdout and where read
as a number by UML, when calling read_output().  I verified the obtained
number corresponded to "BUG:").

The added use of __cant_sleep() is not a new bug since __cant_sleep() is
already used in the same function - passing an atomicity parameter would be
better but it would require huge change, stating that this function must not
be called in atomic context and can sleep is a better idea (will make sure of
this gradually).

Also the checks for 'ati_remote->inbuf != NULL' and 'ati_remote->outbuf !=

[PATCH] Enforce "unsigned long flags;" when spinlocking

Make it break or warn if you pass to spin_lock_irqsave() and friends
something different from "unsigned long flags;".  Suprisingly large amount
of these was caught by recent commit
c53421b18f205c5f97c604ae55c6a921f034b0f6 and others.

Idea is largely from FRV typechecking. Suggestions from Andrew Morton.
All stupid typos in first version fixed.

Passes allmodconfig on i386, x86_64, alpha, arm as well as my usual config.

Note #1: checking with sparse is still needed, because a driver can save
 and pass around flags or something. So far patch is very intrusive.
Note #2: techically, we should break only if
sizeof(flags) < sizeof(unsigned long),
 however, the more pain for getting suspicious code into kernel,
 the better.

I got a lockdep warning when running "rtctest" so I though it'd be good
to see what was up.

 - The warning was for rtc->irq_task_lock, gotten from rtc_update_irq()
   by irq handlerss ... but in a handful of other cases, grabbed without
   blocking IRQs.

 - Some callers to rtc_update_irq() were not ensuring IRQs were blocked,
   yet the routine expects that; make sure all callers block IRQs.

It would appear that RTC API tests haven't been part of anyone's kernel
regression test suite recently, at least not with lockdep running.

Fix bug in certain error paths of lookup routines.  The request object was
reused for sending FORGET, which is illegal.  This bug could cause an Oops
in 2.6.18.  In earlier versions it might silently corrupt memory, but this
is very unlikely.

These error paths are never triggered by libfuse, so this wasn't noticed

interface.

from working.

First, we pass "file1 dir2" to the gen_initramfs_list.sh script, which it

[PATCH] x86_64: fix bad page state in process 'swapper'

find_min_pfn_for_node() and find_min_pfn_with_active_regions() both
depend on a sorted early_node_map[].  However, sort_node_map() is being
called after fin_min_pfn_with_active_regions() in
free_area_init_nodes().

In most cases, this is ok, but on at least one x86_64, the SRAT table
caused the E820 ranges to be registered out of order.  This gave the
wrong values for the min PFN range resulting in some pages not being
initialised.

This patch sorts the early_node_map in find_min_pfn_for_node().  It has
been boot tested on x86, x86_64, ppc64 and ia64.

12 years ago[AGP] Allocate AGP pages with GFP_DMA32 by default
Linus Torvalds [Wed, 22 Nov 2006 22:55:29 +0000]
[AGP] Allocate AGP pages with GFP_DMA32 by default

Not all graphic page remappers support physical addresses over the 4GB
mark for remapping, so while some do (the AMD64 GART always did, and I
just fixed the i965 to do so properly), we're safest off just forcing
GFP_DMA32 allocations to make sure graphics pages get allocated in the
low 32-bit address space by default.

AGP sub-drivers that really care, and can do better, could just choose
to implement their own allocator (or we could add another "64-bit safe"
default allocator for their use), but quite frankly, you're not likely
to care in practice.

So for now, this trivial change means that we won't be allocating pages
that we can't map correctly by mistake on x86-64.

[ On traditional 32-bit x86, this could never happen, because GFP_KERNEL
  would never allocate any highmem memory anyway ]

Linus Torvalds [Wed, 22 Nov 2006 17:37:54 +0000]
[AGP] Fix intel 965 AGP memory mapping function

This introduces a i965-specific "mask_memory()" function that knows
about the extended physical addresses that the i965 supports.  This
allows us to correctly map in physical memory in the >4GB range into the
GTT.

Also simplify/clean-up the i965 case for the aperture sizing by just
returning the fixed 512kB size from "fetch_size()".  We don't really
care that not all of the aperture may be visible - the only thing that
cares about the aperture size is the Intel "stolen memory" calculation,
which depends on the fixed size.

Linus Torvalds [Wed, 22 Nov 2006 17:32:06 +0000]
Don't call "note_interrupt()" with irq descriptor lock held

This reverts commit f72fa707604c015a6625e80f269506032d5430dc, and solves
the problem that it tried to fix by simply making "__do_IRQ()" call the
note_interrupt() function without the lock held, the way everybody else
does.

It should be noted that all interrupt handling code must never allow the
descriptor actors to be entered "recursively" (that's why we do all the
magic IRQ_PENDING stuff in the first place), so there actually is
exclusion at that much higher level, even in the absense of locking.

12 years agoAdd "pure_initcall" for static variable initialization
Linus Torvalds [Mon, 20 Nov 2006 19:47:18 +0000]
Add "pure_initcall" for static variable initialization

This is a quick hack to overcome the fact that SRCU currently does not
allow static initializers, and we need to sometimes initialize those
things before any other initializers (even "core" ones) can do so.

Currently we don't allow this at all for modules, and the only user that
needs is right now is cpufreq. As reported by Thomas Gleixner:

   "Commit b4dfdbb3c707474a2254c5b4d7e62be31a4b7da9 ("[PATCH] cpufreq:

Linus Torvalds [Sat, 18 Nov 2006 03:31:09 +0000]
Revert "ACPI: created a dedicated workqueue for notify() execution"

This reverts commit 37605a6900f6b4d886d995751fcfeef88c4e462c.

Again.

This same bug has now been introduced twice: it was done earlier by
commit b8d35192c55fb055792ff0641408eaaec7c88988, only to be reverted
last time in commit 72945b2b90a5554975b8f72673ab7139d232a121.

We must NOT try to queue up notify handlers to another thread than the
normal ACPI execution thread, because the notifications on some systems
seem to just keep on accumulating until we run out of memory and/or
threads.

Keeping events within the one deferred execution thread automatically
throttles the events properly.

At least the Compaq N620c will lock up completely on the first thermal
event without this patch reverted.

12 years agox86: be more careful when walking back the frame pointer chain
Linus Torvalds [Fri, 17 Nov 2006 19:14:56 +0000]
x86: be more careful when walking back the frame pointer chain

When showing the stack backtrace, make sure that we never accept not
only an unchanging frame pointer, but also a frame pointer that moves
back down the stack frame.  It must always grow up (toward older stack
frames).

I doubt this has triggered, but a subtly corrupt stack with extremely
unlucky contents could cause us to loop forever on a bogus endless frame
pointer chain.

This review was triggered by much worse problems happening in some of
the other stack unwinding code.

Ingo Molnar [Fri, 17 Nov 2006 13:26:18 +0000]
[PATCH] i386/x86_64: ACPI cpu_idle_wait() fix

The scheduler on Andreas Friedrich's hyperthreading system stopped
working properly: the scheduler would never move tasks to another CPU!
The lask known working kernel was 2.6.8.

After a couple of attempts to corner the bug, the following smoking gun
was found:

  BIOS reported wrong ACPI idfor the processor
  CPU#1: set_cpus_allowed(), swapper:1, 3 -> 2
   [<c0103bbe>] show_trace_log_lvl+0x34/0x4a
   [<c0103ceb>] show_trace+0x2c/0x2e
   [<c01045f8>] dump_stack+0x2b/0x2d
   [<c0116a77>] set_cpus_allowed+0x52/0xec
   [<c0101d86>] cpu_idle_wait+0x2e/0x100
   [<c0259c57>] acpi_processor_power_exit+0x45/0x58
   [<c0259752>] acpi_processor_remove+0x46/0xea

   [<c04ab2d7>] acpi_processor_init+0x57/0x77
   [<c01004d7>] init+0x146/0x2fd
   [<c0103a87>] kernel_thread_helper+0x7/0x10

a quick look at cpu_idle_wait() shows how broken that code is
on i386: it changes the init task's affinity map but never
restores it ...

and because all userspace tasks get forked by init, they all
inherited that single-CPU affinity mask. x86_64 cloned this
bug too.

this crash happened because it did not sanitize the dwarf2 data it
got, and got an unaligned stack pointer - which happily walked past
the process stack (and eventually reached the end of kernel memory
and pagefaulted there) due to this naive iteration condition:

        HANDLE_STACK (((long) stack & (THREAD_SIZE-1)) != 0);

note that i386 is alot more conservative when it comes to trusting
stack pointers:

  static inline int valid_stack_ptr(struct thread_info *tinfo, void *p)
  {
         return  p > (void *)tinfo &&
                 p < (void *)tinfo + THREAD_SIZE - 3;
  }

but the x86_64 code did not take this bit of i386 code.

The fix is to align the stack pointer.

lkkbd: Remove my old snail-mail address

I moved to a different town and my old snail-mail address is invalid
now.  Also, there's no need at all to have any address like that in
the sources, so remove it completely.

Linus Torvalds [Fri, 17 Nov 2006 06:18:28 +0000]
Fix generic fb_ddc i2c edid probe msg

Benh points out that the msgs[0].flags entry never got initialized, and
since it's an automatic stack allocation, it could have any random
value, which is bad.

Rewrite the initializer to explicitly initialize all fields of the small
i2c_msg structure array we generate.  Just to keep it all obvious, let's
handle msgs[1].buf in the same initializer while we're at it, instead of
initializing that one separately later.

[PATCH] Fix radeon DDC regression

When radeonfb was changed to use the new "generic" ddc, a bit of
code initializing the GPIO lines was lost, causing it to not work
if the firmware didn't configure them properly, which seems to
happen on some cards.

Olaf Hering [Thu, 9 Nov 2006 03:58:07 +0000]
USB: correct keymapping on Powerbook built-in USB ISO keyboards

similar to the version in adbhid_input_register(): The '<>' key and the
'^°' key on a german keyboard is swapped.  Provide correct keys to
userland, external USB keyboards will not work correctly when the
'badmap'/'goodmap' workarounds from xkeyboard-config are used.

It is expected that distributions drop the badmap/goodmap part from
keycodes/macintosh in the xkeyboard-config package.

This is probably 2.6.18.x material, if major distros settle on 2.6.18.

USB: OHCI: fix root-hub resume bug

When a suspended OHCI controller sees a port's status change, it sets
both the Root-Hub-Status-Change and the Resume-Detect bits in the
Interrupt Status register.  Processing both these bits, the driver
tries to resume the root hub twice!

This patch (as807) fixes the bug by ignoring RD if RHSC is set.  It
also prints a slightly more informative log message when a
remote-wakeup event occurs.

to bcd's other than 0x0110. But while it breaks those of a larger bcd,
