Our write() system call has always been atomic in the sense that you get
the expected thread-safe contiguous write, but we haven't actually
guaranteed that concurrent writes are serialized wrt f_pos accesses, so
threads (or processes) that share a file descriptor and use "write()"
concurrently would quite likely overwrite each others data.
This violates POSIX.1-2008/SUSv4 Section XSI 2.9.7 that says:
"2.9.7 Thread Interactions with Regular File Operations
All of the following functions shall be atomic with respect to each
other in the effects specified in POSIX.1-2008 when they operate on
regular files or symbolic links: [...]"
and one of the effects is the file position update.
This unprotected file position behavior is not new behavior, and nobody
has ever cared. Until now. Yongzhi Pan reported unexpected behavior to
Michael Kerrisk that was due to this.
This resolves the issue with a f_pos-specific lock that is taken by
read/write/lseek on file descriptors that may be shared across threads
or processes.

We're now blacklisting "Crucial_CT???M500SSD1" and
"Crucial_CT???M500SSD3". Also, "Micron_M500*" is blacklisted which is
about the same devices as the crucial branded ones. Let's merge the
two Crucial M500 entries and widen the match to
"Crucial_CT???M500SSD*" so that we don't have to fiddle with new
entries for similar devices.

When trying to map a bunch of instruction addresses to their respective
threads, I kept getting a lot of bogus entries [I forget the exact
reason as I patched my code months ago].
Looking through ip__resolve_ams, I noticed the check for
if (al.sym)
and realized, most times I have an al.map definition but sometimes an
al.sym is undefined. In the cases where al.sym is undefined, the loop
keeps going even though a valid al.map exists.
Modify this check to use the more reliable al.map. This fixed my bogus
entries.

Now that every DAI has a component we can track the DAIs on a per component
basis. This simplifies the DAI lookup when we are only interested in DAIs of a

snd_soc_register_dais() looks up the CODEC that is registering the DAIs by

avoiding the lookup.

snd_soc_register_dais() has basically the same code as snd_soc_register_dai(),
but running in a loop. The only difference is that snd_soc_register_dai() calls
fmt_single_name() to generate the DAIs name and snd_soc_register_dais() calls
fmt_multiple_name(). This patch pushes the check in __snd_soc_register_component()
which decides whether to call snd_soc_register_dai() or snd_soc_register_dais()
to snd_soc_register_dais() to decide which naming scheme to use. This allows us
to remove snd_soc_register_dai().
The patch also updates snd_soc_register_dais() to unregister every DAI it finds
for the component rather than trying to unregister one DAI for each DAI that was
registered. Both have the same result since there won't be more DAIs than what
have been registered, but the former is easier to implement.

Use table based setup to register the DAPM widgets and routes. This on one hand
makes the code a bit shorter and cleaner and on the other hand the board level
DAPM elements get registered in the card's DAPM context rather than in the
CODEC's DAPM context.
While we are at it also remove the snd_soc_dapm_enable_pin() in the init
callback. Pins are enabled by default.

In the first place, the loop 'for' in the macro 'for_each_isci_host'
(drivers/scsi/isci/host.h:314) is incorrect, because it accesses
the 3rd element of 2 element array. After the 2nd iteration it executes
the instruction:
ihost = to_pci_info(pdev)->hosts[2]
(while the size of the 'hosts' array equals 2) and reads an
out of range element.
In the second place, this loop is incorrectly optimized by GCC v4.8
(see http://marc.info/?l=linux-kernel&m=138998871911336&w=2).
As a result, on platforms with two SCU controllers,
the loop is executed more times than it can be (for i=0,1 and 2).
It causes kernel panic during entering the S3 state
and the following oops after 'rmmod isci':

Remove an erroneous BUG_ON() in the case of a hard reset timeout. The
reset timeout handler puts the port into the "awaiting link-up" state.
The timeout causes the device to be disconnected and we need to be in
the awaiting link-up state to re-connect the port. The BUG_ON() made
the incorrect assumption that resets never timeout and we always
complete the reset in the "resetting" state.
Testing this patch also uncovered that libata continues to attempt to
reset the port long after the driver has torn down the context. Once
the driver has committed to abandoning the link it must indicate to
libata that recovery ends by returning -ENODEV from
->lldd_I_T_nexus_reset().

security_xfrm_policy_alloc can be called in atomic context so the
allocation should be done with GFP_ATOMIC. Add an argument to let the
callers choose the appropriate way. In order to do so a gfp argument
needs to be added to the method xfrm_policy_alloc_security in struct
security_operations and to the internal function
selinux_xfrm_alloc_user. After that switch to GFP_ATOMIC in the atomic
callers and leave GFP_KERNEL as before for the rest.
The path that needed the gfp argument addition is:
security_xfrm_policy_alloc -> security_ops.xfrm_policy_alloc_security ->
all users of xfrm_policy_alloc_security (e.g. selinux_xfrm_policy_alloc) ->
selinux_xfrm_alloc_user (here the allocation used to be GFP_KERNEL only)
Now adding a gfp argument to selinux_xfrm_alloc_user requires us to also
add it to security_context_to_sid which is used inside and prior to this
patch did only GFP_KERNEL allocation. So add gfp argument to
security_context_to_sid and adjust all of its callers as well.

This fixes CVE-2014-0102.
The following command sequence produces an oops:
keyctl new_session
i=`keyctl newring _ses @s`
keyctl link @s $i
The problem is that search_nested_keyrings() sees two keyrings that have
matching type and description, so keyring_compare_object() returns true.
s_n_k() then passes the key to the iterator function -
keyring_detect_cycle_iterator() - which *should* check to see whether this is
the keyring of interest, not just one with the same name.
Because assoc_array_find() will return one and only one match, I assumed that
the iterator function would only see an exact match or never be called - but
the iterator isn't only called from assoc_array_find()...
The oops looks something like this:
kernel BUG at /data/fs/linux-2.6-fscache/security/keys/keyring.c:1003!
invalid opcode: 0000 [#1] SMP
...
RIP: keyring_detect_cycle_iterator+0xe/0x1f

key_link+0x4e/0x85
keyctl_keyring_link+0x60/0x81
SyS_keyctl+0x65/0xe4
tracesys+0xdd/0xe2
The fix is to make keyring_detect_cycle_iterator() check that the key it
has is the key it was actually looking for rather than calling BUG_ON().
A testcase has been included in the keyutils testsuite for this:
http://git.kernel.org/cgit/linux/kernel/git/dhowells/keyutils.git/commit/?id=891f3365d07f1996778ade0e3428f01878a1790b

commit 25bfb1dd4ba3b2d9a49ce9d9b0cd7be1840e15ed

prematurely and cause MMIO read cycles to be unresponsive. On some
systems, it may generate NMI in the bnx2's pci shutdown handler.

Currently the FLL configuration is calculated before it is known which
FLL path the configuration will be applied to. Newer versions of the IP
have differences in the configuration required for each FLL path, which
makes it complicated to calculate the FLL configuration in advance.
This patch simply checks the validity of a requested input and output
frequency before we know which FLL path they will be applied to and
saves the actual calculation of the configuration until we know where
the settings will be applied.

Since we know in arizona_apply_fll if we are setting the sync or ref
path there is no need to set the outdiv seperately anymore. This patch
moves this from arizona_enable_fll to arizona_apply_fll.
