This breaks out the ptrace handling from get_signal_to_deliver into a
new subroutine. The actual code there doesn't change, and it gets
inlined into nearly identical compiled code. This makes the function
substantially shorter and thus easier to read, and it nicely isolates
the ptrace magic.

When I ran a test program to fork mass processes and at the same time
'cat /cgroup/tasks', I got the following oops:
------------[ cut here ]------------

Fixing recursive fault but reboot is needed!
After digging into the code and debugging, I finlly found out a race
situation:
do_exit()
->cgroup_exit()
->if (!list_empty(&tsk->cg_list))
list_del(&tsk->cg_list);
cgroup_iter_start()
->cgroup_enable_task_cg_list()
->list_add(&tsk->cg_list, ..);
In this case the list won't be deleted though the process has exited.
We got two bug reports in the past, which seem to be the same bug as
this one:
http://lkml.org/lkml/2008/3/5/332
http://lkml.org/lkml/2007/10/17/224
Actually sometimes I got oops on list_del, sometimes oops on list_add.
And I can change my test program a bit to trigger other oops.
The patch has been tested both on x86_32 and x86_64.

Much like we added a network node cache, this patch adds a network port
cache. The design is taken almost completely from the network node cache
which in turn was taken from the network interface cache. The basic idea is
to cache entries in a hash table based on protocol/port information. The
hash function only takes the port number into account since the number of
different protocols in use at any one time is expected to be relatively
small.

Introduce the concept of a permissive type. A new ebitmap is introduced to
the policy database which indicates if a given type has the permissive bit
set or not. This bit is tested for the scontext of any denial. The bit is
meaningless on types which only appear as the target of a decision and never
the source. A domain running with a permissive type will be allowed to
perform any action similarly to when the system is globally set permissive.

This changes checks related to ptrace to get rid of the ptrace_sid tracking.
It's good to disentangle the security model from the ptrace implementation
internals. It's sufficient to check against the SID of the ptracer at the

This patch turns the case where we have a call into avc_has_perm with no
requested permissions into a BUG_ON. All callers to this should be in
the kernel and thus should be a function we need to fix if we ever hit
this. The /selinux/access permission checking it done directly in the
security server and not through the avc, so those requests which we
cannot control from userspace should not be able to trigger this BUG_ON.

Adds a new open permission inside SELinux when 'opening' a file. The idea
is that opening a file and reading/writing to that file are not the same
thing. Its different if a program had its stdout redirected to /tmp/output
than if the program tried to directly open /tmp/output. This should allow
policy writers to more liberally give read/write permissions across the
policy while still blocking many design and programing flaws SELinux is so
good at catching today.

The RCU/spinlock locking approach for the nlbl_state in the sk_security_struct
was almost certainly overkill. This patch removes both the RCU and spinlock
locking, relying on the existing socket locks to handle the case of multiple
writers. This change also makes several code reductions possible.
Less locking, less code - it's a Good Thing.

associated comment about gcc behavior really aren't needed; all of these
functions are marked STATIC which includes noinline, and the stack usage
won't be a problem.
This effectively just removes the forward declarations and moves
xfs_ioctl() back to the end of the file.

Fix up xfs_bmap_compute_maxlevels() to account for the case when we go
from using attr2 to using attr1. In that case attr1 will no longer
necessarily be at m_attr_offset>>3, but could be at a different value for
di_forkoff. Therefore, we return the worst case scenario using MINDBTPTRS
and MINABTPTRS, as this function is used for determining the maximum log
space.

In the case where we mount a filesystem which was previously using the
attr2 format as attr1, returning the default mp->m_attroffset instead of
the per-inode di_forkoff for inline attribute fit calculations, may result
in corruption, if for example, the data fork is already taking more space
than the default fork offset and we try to add an extended attribute. Fix
tested by xfstests/186.

xfssyncd triggers the logging of superblock counters every 30s if the
filesystem is made with lazy-count=1. This will prevent disks from idling
and spinning down as there will be a log write every 30s. With the way
counter recovery works for lazy-count=1, this code is unnecessary and
provides no real benefit, so just remove it.

Fix a logic error in xfs_alloc_ag_vextent_near(). This is a regression
introduced by the error handling changes.

Unmounting the log can fail. unlikely, but it can. Catch all the error
conditions an make sure it's propagated upwards.

xfs_log_force() is declared to return an error, but we almost never check
it. We don't need to check it in most cases; if there's a log I/O error
then we'll be shutting down the filesystem anyway and that means we'll
catch the error somewhere else.
However, on certain calls we should be returning an error - sync
transactions, fsync, sync writes, etc. so this isn't a pure black and
white distinction. Hence make xfs_log_force() a void function that issues
a warning to the syslog on error, and call _xfs_log_force() in all the
places where we actually care about the error status returned.

xfs_buf_associate_memory() can fail, but the return is never checked.
Propagate the error through XFS_BUF_SET_PTR() so that failures are
detected.

xfs_inactive() fails to report errors when committing the inactive
transaction. Hence we can get silent failures either finishing off the
truncation or committing the transaction. Even if we get errors, we need
to continue, so simply warn loudly to the system if we get errors here.

Catch errors from xfs_imap() in log recovery when we might be trying to
map an invalid inode number due to a corrupted log.
