12 years agoocfs2: reverse inline-data truncate args
Mark Fasheh [Tue, 20 Nov 2007 19:56:39 +0000]
ocfs2: reverse inline-data truncate args

ocfs2_truncate() and ocfs2_remove_inode_range() had reversed their "set
i_size" arguments to ocfs2_truncate_inline(). Fix things so that truncate
sets i_size, and punching a hole ignores it.

This exposed a problem where punching a hole in an inline-data file wasn't
updating the page cache, so fix that too.

12 years agoocfs2: Remove bug statement in ocfs2_dentry_iput()
Mark Fasheh [Thu, 8 Nov 2007 00:35:14 +0000]
ocfs2: Remove bug statement in ocfs2_dentry_iput()

The existing bug statement didn't take into account unhashed dentries which
might not have a cluster lock on them. This could happen if a node exporting
the file system via NFS is rebooted, re-exported to nfs clients and then
unmounted. It's fine in this case to not have a dentry cluster lock.

Just remove the bug statement and replace it with an error print, which
does the proper checks. Though we want to know if something has happened
which might have prevented a cluster lock from being created, it's
definitely not necessary to panic the machine for this.

ide: skip ide_wait_not_busy() on noprobe-disks

There is a problem in some hardware where the kernel will stall for
35 seconds waiting for disks that don't exist. This patch will skip
waiting for the BSY-bit on IDE drives to go away if you set "hdx=noprobe"
as a kernel option and the disk is not marked as 'present' (like when
you set the geometry by hand).

If no noprobe-option is set the code will work (more or less) as the
original but if set the code will skip the ide_wait_not_busy() for
that drive. Even if there would be a drive there and it is still busy
afterwards it should not matter since it isn't probed for later.

The code also honors the MAX_DRIVES variable instead of assuming that
there will be two harddrives on the bus.

KVM: x86 emulator: fix JMP_REL

Change JMP_REL to call to register_address_increment(): the operands size
should not effect the calculation of the eip, instead the ad_bytes should
affect it.

scatterlist: add more safeguards

Add more safeguards to protect against misinterpreting a chain entry
as a normal scatterlist and vice-versa.

* Make sure the entry isn't a chain when assigning and reading a
  normal sg.

* Clear offset and length when chaining.

12 years agoblktrace: Make sure BLKTRACETEARDOWN does the full cleanup.
Aneesh Kumar K.V [Wed, 21 Nov 2007 11:25:41 +0000]
blktrace: Make sure BLKTRACETEARDOWN does the full cleanup.

if blktrace program segfault it will not be able
to call BLKTRACETEARDOWN. Now if we run the blktrace
again that would result in a failure to create the
block/<device> debugfs directory.This will result
in blk_remove_root() to be called which will set
blk_tree_root to NULL. But the  debugfs block dir
still exist because it contain subdirectory.

Now if we try to fix it using BLKTRACETEARDOWN
it won't work because blk_tree_root is NULL.

Fix the same.

Tested as below

plip: fix parport_register_device name parameter

Plip passes a string "name" that is allocated on stack to
parport_register_device.  parport_register_device holds the pointer to
"name" and when the registering function exits, it points nowhere.

On some machine, this bug causes bad names to appear in /proc, such as
/proc/sys/dev/parport/parport0/devices/T^/�X^/�, on others, the plip
proc node is completely missing.

local_softirq_panding 08" that happens on some machines with NOHZ and

[XFRM]: Fix leak of expired xfrm_states

The xfrm_timer calls __xfrm_state_delete, which drops the final reference
manually without triggering destruction of the state. Change it to use
xfrm_state_put to add the state to the gc list when we're dropping the
last reference. The timer function may still continue to use the state
safely since the final destruction does a del_timer_sync().

12 years agox86: correctly set UTS_MACHINE for "make ARCH=x86"
Andreas Herrmann [Mon, 19 Nov 2007 22:58:57 +0000]
x86: correctly set UTS_MACHINE for "make ARCH=x86"

For a kernel built with "make ARCH=x86" the following system
information is displayed when running the new kernel

    $ uname -m
    x86

On some i386 systems (e.g. K7) we even have the following information

    $ uname -m
    x66

This is weird. The usual information for "uname -m" should be "x86_64"
on 64-bit and "i386" or "i686" on 32-bit.

This patch fixes the issue by setting UTS_MACHINE to "i386" for 32-bit
kernel builds and to "x86_64" for 64-bit kernel builds. I.e., "x86"
won't be used for UTS_MACHINE anymore.

time: add ADJ_OFFSET_SS_READ

Michael Kerrisk reported that a long standing bug in the adjtimex()
system call causes glibc's adjtime(3) function to deliver the wrong
results if 'delta' is NULL.

add the ADJ_OFFSET_SS_READ API detail, which will be used by glibc
to fix this API compatibility bug.

Also see: http://bugzilla.kernel.org/show_bug.cgi?id=6761

[ mingo@elte.hu: added patch description and made it backwards compatible ]

NOTE: the new flag is defined 0xa001 so that it returns -EINVAL on
older kernels - this way glibc can use it safely. Suggested by Ulrich
Drepper.

x86: export the symbol empty_zero_page on the 32-bit x86 architecture

The latest KVM driver wants to use the empty_zero_page symbol, and it's
not exported in 32-bit x86 (although it is exported by x86_64, s390, and
uml architectures).

12 years agopci: use pci=bfsort for HP DL385 G2, DL585 G2
Michal Schmidt [Mon, 26 Nov 2007 19:42:19 +0000]
pci: use pci=bfsort for HP DL385 G2, DL585 G2

HP ProLiant systems DL385 G2 and DL585 G2 need pci=bfsort to enumerate PCI
devices in the expected order.

Matt sayeth:

  biosdevname is a userspace app I wrote to help solve this so we don't need
  to patch the kernel for future systems.  It's not integrated into any
  distributions properly yet, but is included in openSUSE 10.3 and Fedora 8
  for people who want to download and install it there.  It acts as a udev
  helper.

  For the time being, patching the kernel is necessary.  I really hope
  biosdevname eliminates that need in future distributions.

12 years agox86: correctly set UTS_MACHINE for "make ARCH=x86"
Andreas Herrmann [Mon, 26 Nov 2007 19:42:19 +0000]
x86: correctly set UTS_MACHINE for "make ARCH=x86"

x86: correctly set UTS_MACHINE for "make ARCH=x86"

For a kernel built with "make ARCH=x86" the following system
information is displayed when running the new kernel

    $ uname -m
    x86

On some i386 systems (e.g. K7) we even have the following information

    $ uname -m
    x66

This is weird. The usual information for "uname -m" should be "x86_64"
on 64-bit and "i386" or "i686" on 32-bit.

This patch fixes the issue by setting UTS_MACHINE to "i386" for 32-bit
kernel builds and to "x86_64" for 64-bit kernel builds. I.e., "x86"
won't be used for UTS_MACHINE anymore.

12 years agox86: printk kernel version in WARN_ON and other dump_stack users
Arjan van de Ven [Mon, 26 Nov 2007 19:42:19 +0000]
x86: printk kernel version in WARN_ON and other dump_stack users

today, all oopses contain a version number of the kernel, which is nice
because the people who actually do bother to read the oops get this
vital bit of information always without having to ask the reporter in
another round trip.

However, WARN_ON() and many other dump_stack() users right now lack this
information; the patch below adds this. This information is essential
for getting people to use their time effectively when looking at these
things; in addition, it's essential for tools that try to collect
statistics about defects.

Please consider, since its so simple and important for long term kernel
quality processes.

The code is identical between 32/64 bit; a lot of this code should be
unified over time, the patch keeps the identical-ness intact.
