arch_prctl.  A process calling arch_prctl to set %fs would lose it on the

[PATCH] bluetooth: fix socket locking in hci_sock_dev_event()

[Bluetooth] Fix socket locking in hci_sock_dev_event()

hci_sock_dev_event() uses bh_lock_sock() to lock the socket lock.
This is not deadlock-safe against locking of the same socket lock in
l2cap_connect_cfm() from softirq context. In addition to that,
hci_sock_dev_event() doesn't seem to be called from softirq context,
so it is safe to use lock_sock()/release_sock() instead.

The lockdep warning can be triggered on my T42p simply by switching
the Bluetooth off by the keyboard button.

[PATCH] x86_64: fix 2.6.18 regression - PTRACE_OLDSETOPTIONS should be accepted

Also PTRACE_OLDSETOPTIONS should be accepted, as done by kernel/ptrace.c
and forced by binary compatibility.  UML/32bit breaks because of this -
since it is wise enough to use PTRACE_OLDSETOPTIONS to be binary compatible
with 2.4 host kernels.

Until 2.6.17 (commit f0f2d6536e3515b5b1b7ae97dc8f176860c8c2ce) we had:

       default:
                return sys_ptrace(request, pid, addr, data);

Instead here we have:
        case PTRACE_GET_THREAD_AREA:
case ...:
                return sys_ptrace(request, pid, addr, data);

        default:
                return -EINVAL;

This change was a style change - when a case is added, it must be
explicitly tested this way.  In this case, not enough testing was done.

[BRIDGE]: adding new device to bridge should enable if up

One change introduced by the workqueue removal patch is that adding an
interface that is up to a bridge which is also up does not ever call
br_stp_enable_port(), leaving the port in DISABLED state until we do
ifconfig down and up or link events occur.

The following patch to the br_add_if function fixes it.
This is a regression introduced in 2.6.21.

[IPSEC]: xfrm_policy delete security check misplaced

The security hooks to check permissions to remove an xfrm_policy were
actually done after the policy was removed.  Since the unlinking and
deletion are done in xfrm_policy_by* functions this moves the hooks
inside those 2 functions.  There we have all the information needed to
do the security check and it can be done before the deletion.  Since
auditing requires the result of that security check err has to be passed
back and forth from the xfrm_policy_by* functions.

This patch also fixes a bug where a deletion that failed the security
check could cause improper accounting on the xfrm_policy
(xfrm_get_policy didn't have a put on the exit path for the hold taken
by xfrm_policy_by*)

It also fixes the return code when no policy is found in
xfrm_add_pol_expire.  In old code (at least back in the 2.6.18 days) err
wasn't used before the return when no policy is found and so the
initialization would cause err to be ENOENT.  But since err has since
been used above when we don't get a policy back from the xfrm_policy_by*
function we would always return 0 instead of the intended ENOENT.  Also
fixed some white space damage in the same area.

[GFS2] fix hangup when multiple processes are trying to write to the same file

This fixes a problem I encountered while running bonnie++.  When you have one
thread that opens a file and starts to write to it, and then another thread that
tries to open and write to the same file, the second thread will loop forever
trying to grab the inode lock for that inode.  Basically we come in through
generic_buffered_file_write, which calls gfs2_prepare_write, which then attempts
to grab the glock.  Because we don't own the lock, gfs2_prepare_write gets
GLR_TRYFAILED, which returns AOP_TRUNCATED_PAGE to generic_buffered_file_write.
At this point generic_buffered_file_write loops around again and immediately
retries the prepare_write.  This means that the second process never gets off of
the processor in order to allow the process that holds the lock to finish its
work and let go of the lock.  This patch makes gfs2_glock_nq schedule() if it
gets back a GLR_TRYFAILED, which resolves this problem.

This reverts commit 39d61db0edb34d60b83c5e0d62d0e906578cc707.

The commit was buggy in multiple ways:
 - the conversion to ilog2() was incorrect to begin with
 - it tested the wrong #defines, so on all architectures but FRV you'd
   never see the bug except for constant arguments.
 - the new "get_order()" macro used its arguments multiple times, and
   didn't even parenthesize them properly
 - despite the comments, it was not true that you could use it for
   constant initializers, since not all architectures even use the
   generic page.h header file.

All of the problems are individually fixable, but it all boils down to:
better just revert it, and re-do it from scratch.

sysfs_write_file downs buffer->sem while calling flush_write_buffer, and

17 years ago[IA64] kexec: Use EFI_LOADER_DATA for ELF core header
Magnus Damm [Tue, 6 Mar 2007 10:34:26 +0000 (02:34 -0800)]
[IA64] kexec: Use EFI_LOADER_DATA for ELF core header

The address where the ELF core header is stored is passed to the secondary
kernel as a kernel command line option.  The memory area for this header is
also marked as a separate EFI memory descriptor on ia64.

The separate EFI memory descriptor is at the moment of the type
EFI_UNUSABLE_MEMORY.  With such a type the secondary kernel skips over the
entire memory granule (config option, 16M or 64M) when detecting memory.
If we are lucky we will just lose some memory, but if we happen to have
data in the same granule (such as an initramfs image), then this data will
never get mapped and the kernel bombs out when trying to access it.

So this is an attempt to fix this by changing the EFI memory descriptor
type into EFI_LOADER_DATA.  This type is the same type used for the kernel
data and for initramfs.  In the secondary kernel we then handle the ELF
core header data the same way as we handle the initramfs image.

This patch contains the kernel changes to make this happen.  Pretty
straightforward, we reserve the area in reserve_memory().  The address for
the area comes from the kernel command line and the size comes from the
specialized EFI parsing function vmcore_find_descriptor_size().

The kexec-tools-testing code for this can be found here:

[IA64] permon use-after-free fix

Perfmon associates vmalloc()ed memory with a file descriptor, and installs
a vma mapping that memory.  Unfortunately, the vm_file field is not filled
in, so processes with mappings to that memory do not prevent the file from
being closed and the memory freed.  This results in use-after-free bugs and
multiple freeing of pages, etc.

I saw this bug on an Altix on SLES9.  Haven't reproduced upstream but it
looks like the same issue is there.
