x86: don't use 'access_ok()' as a range check in get_user_pages_fast()
It's really not right to use 'access_ok()', since that is meant for the
normal "get_user()" and "copy_from/to_user()" accesses, which are done
through the TLB, rather than through the page tables.
Why? access_ok() does both too few, and too many checks. Too many,
because it is meant for regular kernel accesses that will not honor the
'user' bit in the page tables, and because it honors the USER_DS vs
KERNEL_DS distinction that we shouldn't care about in GUP. And too few,
because it doesn't do the 'canonical' check on the address on x86-64,
since the TLB will do that for us.
So instead of using a function that isn't meant for this, and does
something else and much more complicated, just do the real rules: we
don't want the range to overflow, and on x86-64, we want it to be a
canonical low address (on 32-bit, all addresses are canonical).

ide-cd: prevent null pointer deref via cdrom_newpc_intr
With 2.6.30, the error handling code in cdrom_newpc_intr was changed
to deal with partial request failures by normally completing the 'good'
parts of a request and only 'error' the last (and presumably,
incompletely transferred) bio associated with a particular
request. In order to do this, ide_complete_rq is called over
ide_cd_error_cmd() to partially complete the rq. The block layer
does partial completion only for requests with bio's and if the
rq doesn't have one (eg 'GPCMD_READ_DISC_INFO') the request is
completed as a whole and the drive->hwif->rq pointer set to NULL
afterwards. When calling ide_complete_rq again to report
the error, this null pointer is derefenced, resulting in a kernel
crash.

the remove function itself should be marked with __devexit. Even more so
considering the probe function is marked with __devinit.

ptrace: wait_task_zombie: do not account traced sub-threads
The bug is ancient.
If we trace the sub-thread of our natural child and this sub-thread exits,
we update parent->signal->cxxx fields. But we should not do this until
the whole thread-group exits, otherwise we account this thread (and all
other live threads) twice.
Add the task_detached() check. No need to check thread_group_empty(),
wait_consider_task()->delay_group_leader() already did this.

Host software could issue interrupts to ME firmware, using H_IG bit. While
Setting H_IG bit, host software should preserve all the other bits in H_CSR

the register, then set some bits, and write the whole 32bits back to the
register. And that the special behavior of H_IS (write-one-to-zero) causes problem.
This patch fixes the issue in the following ways:
- Modify heci_set_csr_register() function so that it doesn't change H_IS bit.
- Add interface heci_csr_clear_his() to clear H_IS bit. This function is called
after H_IS checking (dev->host_hw_state & H_IS == H_IS).
- In original heci_csr_disable_interrupts() function, it not only clears H_IE
bit, sometimes it also clears H_IS bit. This patch separates the two parts.
- Avoid calling write_heci_register() function to set H_CSR register directly,

Otherwise in the next time connection, hardware resource may be busy.

When spinlock is nested, and the outside one is spin_lock_bh, the inner
spinlock should also be spin_lock_bh, otherwise it will bring softirq-safe

staging: p9auth: prevent some oopses and memory leaks
Before all testcases, do:
mknod /dev/caphash c 253 0
mknod /dev/capuse c 253 1
This patch does the following:
1. caphash write of > CAP_NODE_SIZE bytes overruns node_ptr->data
(test: cat /etc/mime.types > /dev/caphash)
2. make sure we don't dereference a NULL cap_devices[0].head
(test: cat serge@root@abab > /dev/capuse)
3. don't let strlen dereference a NULL target_user etc
(test: echo ab > /dev/capuse)
4. Don't leak a bunch of memory in cap_write(). Note that
technically node_ptr is not needed for the capuse write case.
As a result I have a much more extensive patch splitting up
cap_write(), but I thought a smaller patch that is easier to test
and verify would be a better start. To test:
cnt=0
while [ 1 ]; do
echo /etc/mime.types > /dev/capuse
if [ $((cnt%25)) -eq 0 ]; then
head -2 /proc/meminfo
fi
cnt=$((cnt+1))
sleep 0.3
done
Without this patch, it MemFree steadily drops. With the patch,
it does not.
I have *not* tested this driver (with or without these patches)
with factotum or anything - only using the tests described above.
