the status block index has changed when servicing the kcq2, we must

8 years agoof/promtree: allow DT device matching by fixing 'name' brokenness (v5)
Andres Salomon [Thu, 24 Feb 2011 06:38:22 +0000]
of/promtree: allow DT device matching by fixing 'name' brokenness (v5)

Commit e2f2a93b, "of/promtree: add package-to-path support to pdt"
changed dp->name from using the 'name' property to using
package-to-path.  This fixed /proc/device-tree creation by eliminating
conflicts between names (the 'name' property provides names like
'battery', whereas package-to-path provides names like
'/foo/bar/battery@0', which we stripped to 'battery@0').  However, it
also breaks of_device_id table matching.

The fix that we _really_ wanted was to keep dp->name based upon
the name property ('battery'), but based dp->full_name upon
package-to-path ('battery@0').  This patch does just that.

This changes all users (except SPARC) of promtree to use the full
result from package-to-path for full_name, rather than stripping the
directory out.  In practice, the strings end up being exactly the
same; this change saves time, code, and memory.

SPARC continues to use the existing build_path_component() code.

v2: combine two patches and revert of_pdt_node_name to original version
v3: use dp->phandle instead of passing around node
v4: warn/bail out for non-sparc archs if pkg2path is not set
v5: split of_pdt_build_full_name into sparc & non-sparc versions
v6: Pass NULL to pkg2path before buf gets assigned.
    Drop check for pkg2path hook on each and every node.
v7: Don't BUG() when unable to get the full_path; create a
    known-unique name instead.

8 years agoblock: blk-flush shouldn't call directly into q->request_fn() __blk_run_queue()
Tejun Heo [Wed, 2 Mar 2011 13:48:06 +0000]
block: blk-flush shouldn't call directly into q->request_fn() __blk_run_queue()

blk-flush decomposes a flush into sequence of multiple requests.  On
completion of a request, the next one is queued; however, block layer
must not implicitly call into q->request_fn() directly from completion
path.  This makes the queue behave unexpectedly when seen from the
drivers and violates the assumption that q->request_fn() is called
with process context + queue_lock.

This patch makes blk-flush the following two changes to make sure
q->request_fn() is not called directly from request completion path.

- blk_flush_complete_seq_end_io() now asks __blk_run_queue() to always
  use kblockd instead of calling directly into q->request_fn().

- queue_next_fseq() uses ELEVATOR_INSERT_REQUEUE instead of
  ELEVATOR_INSERT_FRONT so that elv_insert() doesn't try to unplug the
  request queue directly.

8 years agoext2: Fix link count corruption under heavy link+rename load
Josh Hunt [Thu, 24 Feb 2011 10:48:22 +0000]
ext2: Fix link count corruption under heavy link+rename load

vfs_rename_other() does not lock renamed inode with i_mutex. Thus changing
i_nlink in a non-atomic manner (which happens in ext2_rename()) can corrupt
it as reported and analyzed by Josh.

In fact, there is no good reason to mess with i_nlink of the moved file.
We did it presumably to simulate linking into the new directory and unlinking
from an old one. But the practical effect of this is disputable because fsck
can possibly treat file as being properly linked into both directories without
writing any error which is confusing. So we just stop increment-decrement
games with i_nlink which also fixes the corruption.

xfs: zero proper structure size for geometry calls

Commit 493f3358cb289ccf716c5a14fa5bb52ab75943e5 added this call to
xfs_fs_geometry() in order to avoid passing kernel stack data back
to user space:

+       memset(geo, 0, sizeof(*geo));

Unfortunately, one of the callers of that function passes the
address of a smaller data type, cast to fit the type that
xfs_fs_geometry() requires.  As a result, this can happen:

Kernel panic - not syncing: stack-protector: Kernel stack is corrupted
in: f87aca93

Ryusuke Konishi [Mon, 28 Feb 2011 04:41:11 +0000]
nilfs2: fix regression that i-flag is not set on changeless checkpoints

According to the report from Jiro SEKIBA titled "regression in
2.6.37?"  (Message-Id: <8739n8vs1f.wl%jir@sekiba.com>), on 2.6.37 and
later kernels, lscp command no longer displays "i" flag on checkpoints
that snapshot operations or garbage collection created.

This is a regression of nilfs2 checkpointing function, and it's
critical since it broke behavior of a part of nilfs2 applications.
For instance, snapshot manager of TimeBrowse gets to create
meaningless snapshots continuously; snapshot creation triggers another
checkpoint, but applications cannot distinguish whether the new
checkpoint contains meaningful changes or not without the i-flag.

This patch fixes the regression and brings that application behavior
back to normal.

[CPUFREQ] fix BUG on cpufreq policy init failure

cpufreq_register_driver sets cpufreq_driver to a structure owned (and
placed) in the caller's memory. If cpufreq policy fails in its ->init
function, sysdev_driver_register returns nonzero in
cpufreq_register_driver. Now, cpufreq_register_driver returns an error
without setting cpufreq_driver back to NULL.

Usually cpufreq policy modules are unloaded because they propagate the
error to the module init function and return that.

So a later access to any member of cpufreq_driver causes bugs like:

8 years agodrm/i915: fix memory corruption with GM965 and >4GB RAM
Jan Niehusmann [Tue, 1 Mar 2011 22:24:16 +0000]
drm/i915: fix memory corruption with GM965 and >4GB RAM

On a Thinkpad x61s, I noticed some memory corruption when
plugging/unplugging the external VGA connection. The symptoms are that
4 bytes at the beginning of a page get overwritten by zeroes.
The address of the corruption varies when rebooting the machine, but
stays constant while it's running (so it's possible to repeatedly write
some data and then corrupt it again by plugging the cable).

Further investigation revealed that the corrupted address is
(dev_priv->status_page_dmah->busaddr & 0xffffffff), ie. the beginning of
the hardware status page of the i965 graphics card, cut to 32 bits.

So it seems that for some memory access, the hardware uses only 32 bit

Linus Torvalds [Tue, 1 Mar 2011 21:23:27 +0000]
Revert "TPM: Long default timeout fix"

This reverts commit c4ff4b829ef9e6353c0b133b7adb564a68054979.

Ted Ts'o reports:

 "TPM is working for me so I can log into employer's network in 2.6.37.
  It broke when I tried 2.6.38-rc6, with the following relevant lines
  from my dmesg:

  [   11.081627] tpm_tis 00:0b: 1.2 TPM (device-id 0x0, rev-id 78)

  [   78.040949] tpm_tis 00:0b: Operation Timed out

  This caused me to get suspicious, especially since the _other_ TPM
  commit in 2.6.38 had already been reverted, so I tried reverting
  commit c4ff4b829e: "TPM: Long default timeout fix".  With this commit

Vivek Goyal [Tue, 1 Mar 2011 18:40:54 +0000]
blk-throttle: Do not use kblockd workqueue for throtl work

o Dominik Klein reported a system hang issue while doing some blkio
  throttling testing.


o Some tracing revealed that CFQ was not dispatching any more jobs as
  queue unplug was not happening. And queue unplug was not happening
  because unplug work was not being called as there was one throttling
  work on same cpu which as not finished yet. And throttling work had not
  finished as it was tyring to dispatch a bio to CFQ but all the request
  descriptors were consume to it was put to sleep.

o So basically it is a cyclic dependecny between CFQ unplug work and
  throtl dispatch work. Tejun suggested that use separate workqueue for
  such cases.

o This patch uses a separate workqueue for throttle related work and
  does not rely on kblockd workqueue anymore.

davinci: tnetv107x: fix register indexing for GPIOs numbers > 31

This patch fix a bug in the register indexing for GPIOs numbers >  31
to get the relevant hardware registers of tnetv107x to control the GPIOs.

In the structure tnetv107x_gpio_regs:

struct tnetv107x_gpio_regs {
            u32     idver;
            u32     data_in[3];
            u32     data_out[3];
            u32     direction[3];
            u32     enable[3];

The GPIO hardware register addresses of tnetv107x are stored.
The chip implements 3 registers of each entity to serve 96 GPIOs,
each register provides a subset of 32 GPIOs.
The driver provides these macros: gpio_reg_set_bit, gpio_reg_get_bit
and gpio_reg_clear_bit.

The bug implied the use of macros to access the relevant hardware
register e.g. the driver code used the macro like this:
'gpio_reg_clear_bit(&reg->data_out, gpio)'

But it has to be used like this:
'gpio_reg_clear_bit(reg->data_out, gpio)'.

The different results are shown here:
- &reg->data_out + 1 (it will add the full array size of data_out i.e. 12 bytes)
- reg->data_out + 1 (it will increment only the size of data_out i.e. only 4 bytes)

It loops, but does not advance it's iterator.
NLA_UNSPEC == 0 does not contain a .len in any policy.

Trivially fixed by adding p++.

f_phonet: avoid pskb_pull(), fix OOPS with CONFIG_HIGHMEM

This is similar to what we already do in cdc-phonet.c in the same
situation. pskb_pull() refuses to work with HIGHMEM, even if it is
known that the socket buffer is entirely in "low" memory.

dnet: fix wrong use of platform_set_drvdata()

platform_set_drvdata() was used with argument of incorrect type and
could cause memory corruption. Moreover, because of not setting drvdata
in the correct place not all resources were freed upon module unload.

8 years agonetlink: handle errors from netlink_dump()

netlink: handle errors from netlink_dump()

netlink_dump() may failed, but nobody handle its error.
It generates output data, when a previous portion has been returned to
user space. This mechanism works when all data isn't go in skb. If we
enter in netlink_recvmsg() and skb is absent in the recv queue, the
netlink_dump() will not been executed. So if netlink_dump() is failed
one time, the new data never appear and the reader will sleep forever.

netlink_dump() is called from two places:

1. from netlink_sendmsg->...->netlink_dump_start().
   In this place we can report error directly and it will be returned
   by sendmsg().

2. from netlink_recvmsg
   There we can't report error directly, because we have a portion of
   valid output data and call netlink_dump() for prepare the next portion.
   If netlink_dump() is failed, the socket will be mark as error and the
   next recvmsg will be failed.
