[PATCH] dvb: flexcop: fix USB transfer handling

- driver receives many null TS packets (pid=0x1fff).  They occupy the
  limited USB bandwidth and this leads to loss of video packets.  Enabling the
  null packet filter fixes this.

- packets that flexcop sends to USB have a 2 byte header that has to be

- sometimes a TS packet is split between different urbs.  These parts have

This patch should fix the avc_alloc_node() oom condition that Andrew
reported when no policy is loaded in SELinux.

Prior to this patch, when no policy was loaded, the SELinux "security
server" (policy engine) was only returning allowed decisions for the
requested permissions for each access check.  This caused the cache to

(typically, the no policy loaded state is only for bootstrapping to the
point where we can load an initial policy).

This patch changes the SELinux security server to return the complete
allowed access vector at once, and then to reset the cache after the
initial policy load to flush the initial cache state created during
bootstrapping.

[PATCH] block_read_full_page() get_block() error handling fix

If block_read_full_page() detects an error when running get_block() it will
run SetPageError(), then it will zero out the block in pagecache and will mark
the buffer_head uptodate.

So at the end of readahead we end up with a non-uptodate pagecache page which
is marked PageError.  But it has uptodate buffers.

The pagefault code will run ClearPageError, will launch readpage a second time
and block_read_full_page() will notice the uptodate buffers and will mark the
page uptodate as well.  We end up with an uptodate, !PageError page full of
zeros and the error is lost.

(It seems a little odd that filemap_nopage() runs ClearPageError().  I guess
all of this adds up to meaning that for each attempted access to the page, the
pagefault handler will retry the I/O.  Which is good and bad.  If the app is
ignoring SIGBUS for some reason we could get a lot of back-to-back I/O
errors.)

Fix it by not marking the pagecache buffer_head as uptodate if the attempt to
map that buffer to a disk block failed.

On my IA64 machine, after kernel 2.6.12-rc3 boots, an edge-triggered
interrupt (IRQ 46) keeps triggered over and over again.  There is no IRQ 46

Kernel 2.6.10 and its prior versions have no the problem.  Basically,
kernel 2.6.10 will mask the spurious edge interrupt if the interrupt is
triggered for the second time and its status includes
IRQ_DISABLE|IRQ_PENDING.

Originally, IA64 kernel has its own specific _irq_desc definitions in file
arch/ia64/kernel/irq.c.  The definition initiates _irq_desc[irq].status to
IRQ_DISABLE.  Since kernel 2.6.11, it was moved to architecture independent
codes, i.e.  kernel/irq/handle.c, but kernel/irq/handle.c initiates

  arch/x86_64/kernel/mpparse.c stopped after maxcpus entries, other entries
  were not processed, this causes kernel not to boot on these systems.

TBD: x86_acpiid_to_apicid and bios_cpu_apicid[] seem to be exactly the

[PATCH] x86_64: Add pmtimer support

There are unfortunately more and more multi processor Opteron systems which
don't have HPET timer support in the southbridge.  This covers in particular
Nvidia and VIA chipsets.  They also don't guarantee that the TSCs are
synchronized between CPUs; and especially with MP powernow the systems are
nearly unusable because the time gets very inconsistent between CPUs.

The timer code for x86-64 was originally written under the assumption that we
could fall back to the HPET timer on such systems.  But this doesn't work
there.

Another alternative is to use the ACPI PM timer as primary time source.  This
patch does that.  The kernel only uses PM timer when there is no other choice
because it has some disadvantages.

Ported over from i386.  It should be faster than the i386 version because I
dropped the "read three times" workaround, but is still considerable slower
than HPET and also does not work together with vsyscalls which have to be
disabled.

Andi Kleen [Tue, 17 May 2005 04:53:25 +0000 (21:53 -0700)]
[PATCH] x86_64: Update TSC sync algorithm

The new TSC sync algorithm recently submitted did not work too well.

The result was that some MP machines where the TSC came up of the BIOS very
unsynchronized and that did not have HPET support were nearly unusable because
the time would jump forwards and backwards between CPUs.

After a lot of research ;-) and some more prototypes I ended up with just
using the one from IA64 which looks best.  It has some internal self tuning
that should adapt to changing interconnect latencies.  It holds up in my tests
so far.

I believe it was originally written by David Mosberger, I just ported it over
to x86-64.  See the inline comment for a description.

This cleans up the code because it uses smp_call_function for syncing instead
of having custom hooks in SMP bootup.

Please note that the cycle numbers it outputs are too optimistic because they
do not take into account the latency of WRMSR and RDTSC, which can be hundreds
of cycles.  It seems to be able to sync a dual Opteron to 200-300 cycles,
which is probably good enough.

There is a timing window during AP bootup where interrupts can see
inconsistent time before the TSC is synced.  It is hard to avoid unfortunately
because we can only do the TSC sync after some setup, and we need to enable
interrupts before that.  I just ignored it for now.

Stephen Tweedie [Sat, 14 May 2005 03:31:19 +0000 (23:31 -0400)]
[PATCH] Fix root hole in raw device

[Patch] Fix raw device ioctl pass-through

Raw character devices are supposed to pass ioctls through to the block
devices they are bound to.  Unfortunately, they are using the wrong
function for this: ioctl_by_bdev(), instead of blkdev_ioctl().

ioctl_by_bdev() performs a set_fs(KERNEL_DS) before calling the ioctl,
redirecting the user-space buffer access to the kernel address space.
This is, needless to say, a bad thing.

This was noticed first on s390, where raw IO was non-functioning.  The
s390 driver config does not actually allow raw IO to be enabled, which
was the first part of the problem.  Secondly, the s390 kernel address
space is distinct from user, causing legal raw ioctls to fail.  I've
reproduced this on a kernel built with 4G:4G split on x86, which fails
in the same way (-EFAULT if the address does not exist kernel-side;
returns success without actually populating the user buffer if it does.)

The patch below fixes both the config and address-space problems.  It's
based closely on a patch by Jan Glauber <jang@de.ibm.com>, which has
been tested on s390 at IBM.  I've tested it on x86 4G:4G (split address
space) and x86_64 (common address space).

Kernel-address-space access has been assigned CAN-2005-1264.

[PATCH] uml: Use CONFIG variable for address space size

tt/mem.c still uses hardcoded TOP for i386 instead of CONFIG_TOP_ADDR provided
by subarch's Kconfig_XXXX, which would be right.

[PATCH] uml: Turn literal numbers into symbolic constants

So, there I was, looking at my own code, wondering what the magic setjmp
return values did.  This patch turns the constants that are used to make
requests of the initial thread into meaningful symbols.

Bodo Stroesser [Sat, 7 May 2005 04:30:46 +0000 (21:30 -0700)]
[PATCH] uml: S390 preparation, peekusr/pokeusr defined by subarch

s390 needs to change some parts of arch/um/kernel/ptrace.c.  Thus, the code
regarding PEEKUSER and POKEUSER are shifted to arch/um/sys-<subarch>/ptrace.c.

Also s390 debug registers need to be updated, when singlestepping is switched
on / off.  Thus, setting/resetting of singlestepping is centralized in the new
function set_singlestep(), which also inserts the macro
SUBARCH_SET_SINGLESTEP(mode), if defined.

Finally, s390 has the "ieee_instruction_pointer" in its
registers, which also is allowed to be read via

  ptrace( PTRACE_PEEKUSER, getpid(), PT_IEEE_IP, 0);

To implement this feature, sys_ptrace inserts the macro
SUBARCH_PTRACE_SPECIAL, if defined.
