Input: samsung-keypad - implement runtime power management support

When runtime power management is enabled put the Samsung keypad driver
into suspend mode with wakeups disabled whenever the device is open but
a key is not actually been pressed. As well as saving a trivial amount of
power this will support the use of SoC wide idle modes which put the entire
device into a retention mode and use explicit wakeup sources to exit.

Since not all of the interrupt controllers used with the driver support
set_irq_wake() (though they all do the right thing) and there's a nasty
WARN() when we disable wake after failing to enable it keep track of the
current wake status from runtime PM and only disable wake if we managed
to enable it; I'm not entirely sure why this doesn't affect the existing
uses of the API in the driver.

System suspend is unaffected as the driver core will runtime resume any
suspended devices prior to system suspend.

Lars-Peter Clausen [Tue, 29 Nov 2011 09:27:58 +0000]
Input: remove redundant spi driver bus initialization

In ancient times it was necessary to manually initialize the bus field of an
spi_driver to spi_bus_type. These days this is done in spi_driver_register(),
so we can drop the manual assignment.

The patch was generated using the following coccinelle semantic patch:
// <smpl>
@@
identifier _driver;
@@
struct spi_driver _driver = {
.driver = {
- .bus = &spi_bus_type,
},
};
// </smpl>

Michael S. Tsirkin [Thu, 17 Nov 2011 15:41:15 +0000]
virtio-pci: make reset operation safer

virtio pci device reset actually just does an I/O
write, which in PCI is really posted, that is it
can complete on CPU before the device has received it.

Further, interrupts might have been pending on
another CPU, so device callback might get invoked after reset.

This conflicts with how drivers use reset, which is typically:
reset
unregister
a callback running after reset completed can race with
unregister, potentially leading to use after free bugs.

Fix by flushing out the write, and flushing pending interrupts.

This assumes that device is never reset from
its vq/config callbacks, or in parallel with being
added/removed, document this assumption.

7 years agoeCryptfs: Extend array bounds for all filename chars
Tyler Hicks [Wed, 23 Nov 2011 17:31:24 +0000]
eCryptfs: Extend array bounds for all filename chars

From mhalcrow's original commit message:

    Characters with ASCII values greater than the size of
    filename_rev_map[] are valid filename characters.
    ecryptfs_decode_from_filename() will access kernel memory beyond
    that array, and ecryptfs_parse_tag_70_packet() will then decrypt
    those characters. The attacker, using the FNEK of the crafted file,
    can then re-encrypt the characters to reveal the kernel memory past
    the end of the filename_rev_map[] array. I expect low security
    impact since this array is statically allocated in the text area,
    and the amount of memory past the array that is accessible is
    limited by the largest possible ASCII filename character.

This patch solves the issue reported by mhalcrow but with an
implementation suggested by Linus to simply extend the length of
filename_rev_map[] to 256. Characters greater than 0x7A are mapped to
0x00, which is how invalid characters less than 0x7A were previously
being handled.

Dirty pages weren't being written back when an mmap'ed eCryptfs file was
closed before the mapping was unmapped. Since f_ops->flush() is not
called by the munmap() path, the lower file was simply being released.
This patch flushes the eCryptfs file in the vm_ops->close() path.

regulator: TPS65910: Fix VDD1/2 voltage selector count

Count of selector voltage is required for regulator_set_voltage
to work via set_voltage_sel. VDD1/2 currently have it as zero,
so regulator_set_voltage won't work for VDD1/2.
Update count (n_voltages) for VDD1/2.

Output Voltage = (step value * 12.5 mV + 562.5 mV) * gain

With above expr, number of voltages that can be selected is
step value count * gain count

constant for gain count will be called VDD1_2_NUM_VOLT_COARSE

existing constant for step value count is VDD1_2_NUM_VOLTS,
use VDD1_2_NUM_VOLT_FINE instead to make clear that step value
is not the only component in deciding selectable voltage count

Linus Torvalds [Tue, 22 Nov 2011 23:09:20 +0000]
Revert "of/irq: of_irq_find_parent: check for parent equal to child"

This reverts commit dc9372808412edbc653a675a526c2ee6c0c14a91.

As requested by Ben Herrenschmidt:
  "This breaks some powerpc platforms at least.  The practice of having
   a node provide an explicit "interrupt-parent" property pointing to
   itself is an old trick that we've used in the past to allow a
   device-node to have interrupts routed to different controllers.

   In that case, the node also contains an interrupt-map, so the node is
   its own parent, the interrupt resolution hits the map, which then can
   route each individual interrupt to a different parent."

Grant says:
  "Ah, nuts, yes that is broken then.  Yes, please revert the commit and
   Rob & I will come up with a better solution.

   Rob, I think it can be done by explicitly checking for np ==
   desc->interrupt_parent in of_irq_init() instead of relying on
   of_irq_find_parent() returning NULL."

Btrfs: remove free-space-cache.c WARN during log replay

The log replay code only partially loads block groups, since
the block group caching code is able to detect and deal with
extents the logging code has pinned down.

While the logging code is pinning down block groups, there is
a bogus WARN_ON we're hitting if the code wasn't able to find
an extent in the cache.  This commit removes the warning because
it can happen any time there isn't a valid free space cache
for that block group.

7 years agoVFS: Log the fact that we've given ELOOP rather than creating a loop
David Howells [Tue, 16 Aug 2011 14:31:30 +0000]
VFS: Log the fact that we've given ELOOP rather than creating a loop

To prevent an NFS server from being used to create a directory loop in an NFS
superblock on the client, the following patch was committed:

commit 1836750115f20b774e55c032a3893e8c5bdf41ed
Author: Al Viro <viro@zeniv.linux.org.uk>
Date:   Tue Jul 12 21:42:24 2011 -0400
Subject: fix loop checks in d_materialise_unique()

This causes ELOOP to be reported to anyone trying to access the dentry that
would otherwise cause the kernel to complete the loop.

However, no indication is given to the caller as to why an operation that ought
to work doesn't.  The fault is with the kernel, which doesn't want to try and
solve the problem as it gets horrendously messy if there's another mountpoint
somewhere in the trees being spliced that can't be moved[*].

[*] The real problem is that we don't handle the excision of a subtree that
gets moved _out_ of what we can see.  This can happen on the server where a
directory is merely moved between two other dirs on the same filesystem, but
where destination dir is not accessible by the client.

So, given the choice to return ELOOP rather than trying to reconfigure the
dentry tree, we should give the caller some indication of why they aren't being
allowed to make what should be a legitimate request and log a message.

Btrfs: sectorsize align offsets in fiemap

We've been hitting BUG()'s in btrfs_cont_expand and btrfs_fallocate and anywhere
else that calls btrfs_get_extent while running xfstests 13 in a loop.  This is
because fiemap is calling btrfs_get_extent with non-sectorsize aligned offsets,
which will end up adding mappings that are not sectorsize aligned, which will
cause problems in some cases for subsequent calls to btrfs_get_extent for
similar areas that are sectorsize aligned.  With this patch I ran xfstests 13 in
a loop for a couple of hours and didn't hit the problem that I could previously
hit in at most 20 minutes.  Thanks,

Btrfs: clear pages dirty for io and set them extent mapped

When doing the io_ctl helpers to clean up the free space cache stuff I stopped
using our normal prepare_pages stuff, which means I of course forgot to do
things like set the pages extent mapped, which will cause us all sorts of
wonderful propblems.  Thanks,
