10 years agoMIPS: Fix machine check exception in kmap_coherent()
Kevin Cernekee [Mon, 7 Sep 2009 18:11:31 +0000]
MIPS: Fix machine check exception in kmap_coherent()

On an SMP system with cache aliases, the following sequence of events may
happen:

1) copy_user_highpage() runs on CPU0, invoking kmap_coherent() to create a
   temporary mapping in the fixmap region
2) copy_page() starts on CPU0
3) CPU1 sends CPU0 an IPI asking CPU0 to run local_r4k_flush_cache_page()
4) CPU0 takes the interrupt, interrupting copy_page()
5) local_r4k_flush_cache_page() on CPU0 calls kmap_coherent() again
6) The second invocation of kmap_coherent() on CPU0 tries to use the
   same fixmap virtual address that was being used by copy_user_highpage()
7) CPU0 throws a machine check exception for the TLB address conflict

Fixed by creating an extra set of fixmap entries for use in interrupt
handlers.  This prevents fixmap VA conflicts between copy_user_highpage()
running in user context, and local_r4k_flush_cache_page() invoked from an
SMP IPI.

10 years agoDriver core: allow certain drivers prohibit bind/unbind via sysfs
Dmitry Torokhov [Tue, 13 Oct 2009 03:17:41 +0000]
Driver core: allow certain drivers prohibit bind/unbind via sysfs

Platform drivers registered via platform_driver_probe() can be bound
to devices only once, upon registration, because discard their probe()
routines to save memory. Unbinding the driver through sysfs 'unbind'
leaves the device stranded and confuses users so let's not create
bind and unbind attributes for such drivers.

10 years agoDriver core: fix driver_register() return value
Stas Sergeev [Sat, 17 Oct 2009 20:31:38 +0000]
Driver core: fix driver_register() return value

In this patch:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=16dc42e018c2868211b4928f20a957c0c216126c
the check was added for another driver to already claim the same device
on the same bus. But the returned error code was wrong: to modprobe, the
-EEXIST means that _this_ driver is already installed. It therefore
doesn't produce the needed error message when _another_ driver is trying
to register for the same device.  Returning -EBUSY fixes the problem.

USB: fsl_udc_core: Fix kernel oops on module removal

fsl_udc_release() calls dma_free_coherent() with an inappropriate
device passed to it, and since the device has no dma_ops, the following
oops pops up:

a correct device.

USB: serial: sierra driver autopm fixes

This patch presents fixes for the autosuspend feature implementation in
sierra usb serial driver in  functions sierra_open(), sierra_close() and
stop_read_write_urbs().

The patch "sierra_close() must resume the device before it notifies it
of a closure" submitted by Oliver Neukum on Wed, October 14 has been
merged as fix in sierra_close() function.

The bug fix  in sierra_open() function restores the autopm interface
state on error condition.

The bug fix in in stop_read_write_urbs() function assures that both
receive and interrupt urbs are recycled.

Staging: Panel: prevent driver from calling misc_deregister twice on same ressource

This patch prevents the driver from calling misc_deregister twice on the same
ressouce when unloading the driver.
Unloading the driver without this patch results in a Kernel BUG like this:
Panel driver version 0.9.5 registered on parport0 (io=0x378).
BUG: unable to handle kernel paging request at 0000000000100108

Oops: 0002 [#1] PREEMPT SMP
last sysfs file: /sys/devices/platform/w83627hf.656/in8_input

This patch fixes this issue, although maybe not in the best way possible :)

10 years agoxfs: fix xfs_quota remove error
Ryota Yamauchi [Fri, 30 Oct 2009 08:27:44 +0000]
xfs: fix xfs_quota remove error

The xfs_quota returns ENOSYS when remove command is executed.
Reproducable with following steps.

    # mount -t xfs -o uquota /dev/sda7 /mnt/mp1
    # xfs_quota -x -c off -c remove
    XFS_QUOTARM: Function not implemented.

The remove command is allowed during quotaoff, but xfs_fs_set_xstate()
checks whether quota is running, and it leads to ENOSYS.

To solve this problem, add a check for X_QUOTARM.

10 years agoxfs: free temporary cursor in xfs_dialloc
Eric Sandeen [Fri, 30 Oct 2009 08:27:07 +0000]
xfs: free temporary cursor in xfs_dialloc

Commit bd169565993b39b9b4b102cdac8b13e0a259ce2f seems
to have a slight regression where this code path:

    if (!--searchdistance) {
        /*
         * Not in range - save last search
         * location and allocate a new inode
         */
        ...
        goto newino;
    }

doesn't free the temporary cursor (tcur) that got dup'd in
this function.

This leaks an item in the xfs_btree_cur zone, and it's caught
on module unload:

===========================================================
BUG xfs_btree_cur: Objects remaining on kmem_cache_close()
-----------------------------------------------------------

It seems like maybe a single free at the end of the function might
be cleaner, but for now put a del_cursor right in this code block
similar to the handling in the rest of the function.

10 years agomm: don't call pte_unmap() against an improper pte
Daisuke Nishimura [Mon, 26 Oct 2009 23:50:23 +0000]
mm: don't call pte_unmap() against an improper pte

There are some places where we do like:

pte = pte_map();
do {
(do break in some conditions)
} while (pte++, ...);
pte_unmap(pte - 1);

But if the loop breaks at the first loop, pte_unmap() unmaps invalid pte.

This patch is a fix for this problem.

10 years agocpuidle: always return with interrupts enabled
Kevin Hilman [Mon, 26 Oct 2009 23:50:18 +0000]
cpuidle: always return with interrupts enabled

In the case where cpuidle_idle_call() returns before changing state due to
a need_resched(), it was returning with IRQs disabled.

The idle path assumes that the platform specific idle code returns with
interrupts enabled (although this too is undocumented AFAICT) and on ARM
we have a WARN_ON(!(irqs_disabled()) when returning from the idle loop, so
the user-visible effects were only a warning since interrupts were
eventually re-enabled later.

On x86, this same problem exists, but there is no WARN_ON() to detect it.
As on ARM, the interrupts are eventually re-enabled, so I'm not sure of
any actual bugs triggered by this.  It's primarily a
correctness/consistency fix.

This patch ensures IRQs are (re)enabled before returning.

checkpatch: fix false EXPORT_SYMBOL warning

Ingo reported that the following lines triggered a false warning,

static struct lock_class_key rcu_lock_key;
struct lockdep_map rcu_lock_map =
        STATIC_LOCKDEP_MAP_INIT("rcu_read_lock", &rcu_lock_key);

from kernel/rcutree.c , and the false warning looked like this,

WARNING: EXPORT_SYMBOL(foo); should immediately follow its
function/variable
+EXPORT_SYMBOL_GPL(rcu_lock_map);

We actually should be checking the statement before the EXPORT_* for a
mention of the exported object, and complain where it is not there.

In the following code,

union thread_union init_thread_union
__attribute__((__section__(".data.init_task"))) =
{ INIT_THREAD_INFO(init_task) };

There is a non-conforming declaration. It should really be like the
following,

union thread_union init_thread_union
__attribute__((__section__(".data.init_task"))) = {
INIT_THREAD_INFO(init_task)
};

However, checkpatch doesn't catch this right now because it doesn't
correctly evaluate the "__attribute__".

It is not at all clear that we care what preceeds an assignment style
attribute when we find the open brace.  Relax the test so we do not need
to check the __attribute__.

10 years agocheckpatch: fix false errors due to macro concatenation
Andy Whitcroft [Mon, 26 Oct 2009 23:50:14 +0000]
checkpatch: fix false errors due to macro concatenation

The macro concatenation (##) sequence can cause false errors when checking
macro's.  Checkpatch doesn't currently know about the operator.

For example this line,

+  entry = (struct ftrace_raw_##call *)raw_data;                   \

is correct but it produces the following error,

ERROR: need consistent spacing around '*' (ctx:WxB)
+       entry = (struct ftrace_raw_##call *)raw_data;\
                                          ^

The line above doesn't have any spacing problems, and if you remove the
macro concatenation sequence checkpatch doesn't give any errors.

Extend identifier handling to include ## concatenation within the
definition of an identifier.
